Abstract
This paper presents a puzzle involving embedded attitude reports. We
resolve the puzzle by arguing that attitude verbs take restricted readings:
in some environments the denotation of attitude verbs can be restricted
by a given proposition. For example, when these verbs are embedded in
the consequent of a conditional, they can be restricted by the proposition
expressed by the conditional’s antecedent. We formulate and motivate
two conditions on the availability of verb restrictions: (i) a constraint
that ties the content of restrictions to the “dynamic effects” of sentential
connectives and (ii) a constraint that limits the availability of restriction
effects to present tense verbs with first-person subjects. However, we also
present some cases that make trouble for these conditions, and outline
some possible ways of modifying the view to account for the recalcitrant
data. We conclude with a brief discussion of some of the connections
between our semantics for attitude verbs and issues concerning epistemic
modals and theories of knowledge.

A puzzle
Let us start with a case:
✯ Penultimate draft. Forthcoming in Journal of Semantics.
1
Bill’s Holiday: Chris, Andrew, and I are discussing the details of
Bill’s holiday this summer. We all know that Bill usually says goodbye before embarking on a trip. Chris says ‘I think that Bill is going
to Costa Rica next week’; then Andrew says ‘Actually, I heard that
Bill left for Cuba today’. I think for a moment, then utter (1):
(1)
If Bill is on a plane to Cuba, then I am surprised that he left without
saying goodbye.
(1) is acceptable in the context of Bill’s Holiday. But suppose that unbeknownst
to any of us (2) is true:
(2)
Bill is on a plane to Cuba.
Taking (1) at face value, (3) follows by modus ponens:
(3)
I am surprised that Bill left without saying goodbye.
However, it is difficult to see how (3) could be true in our scenario. For one thing,
I appear to lack any of the standard phenomenology associated with surprise.
For another, it is plausible that a report ‘S is surprised that P’ is true only if
‘S knows that P’ is.1 But given the circumstances it is not at all clear how I
could know whether Bill has left without saying goodbye. So we have a case in
which modus ponens seems to lead from true premises to a false conclusion.2
Other logical rules, e.g. modus tollens, also appear to be threatened: it is not
permissible to infer that (2) is false from (1) along with the unacceptability of
(3).
Importantly, even if—despite all appearances—(3) is true in our scenario,
conditionals similar to (1) raise a further puzzle. Suppose that Jane joins our
discussion in Bill’s Holiday. We all know she is friends with Bill, but we also
know that Bill is more likely to tell one of us about a vacation to Cuba than
he is to tell Jane (suppose he is better friends with us than with her). After
hearing about our discussion, Jane says ‘Oh, I know where Bill is right now. I
1 We will often use normal quotes where, strictly speaking, corner quotes should be used.
No confusion should arise.
2 Some might be inclined to think that (1) really expresses a subjunctive, e.g. ‘If Bill were
on a plane to Cuba, then I would be surprised that he left without saying goodbye’. However,
the inference from ‘If Bill were on a plane to Cuba, then I would be surprised that he left
without saying goodbye’ and ‘Bill is on a plane to Cuba’ to ‘I am surprised that Bill left
without saying goodbye’ is generally considered to be valid (Bennett, 2003). So the original
problem remains.

talked to him on the phone this morning about his plans’. In this context, (4)
is acceptable:
(4)
If Bill is on a plane to Cuba, then I am surprised that Jane knows this
but I don’t.
So too is (5):
(5)
If Bill is on a plane to Cuba, then I am surprised that he departed
without my knowing.
However, if surprise reports are knowledge entailing in the sense mentioned
above, then the consequent of each of (4) and (5) entails something which seems
to be of the form ‘I know that: P and I don’t know that P’, which itself entails
the straightforwardly contradictory ‘I know that P and I don’t know that P’
(taking for granted that knowledge is factive and distributes over conjunction).
It is generally assumed that indicative conditionals with consequents that are
known to be false are unassertable—especially when the antecedents of those
conditionals are not known to be false—so (4) and (5) are predicted to be
unacceptable, contrary to fact.
The conditionals above featured the verb ‘surprise’, but as far as we can
tell the same puzzles arise with virtually all attitude verbs. For instance, it is
quite straightforward to construct similar cases with emotives such as ‘hope’
and ‘regret’:
Tennis: I have been teaching Chris tennis for the last six months
and I know that he loves playing. One day my friend Jane reports
that she saw someone in the distance injure themselves badly on a
tennis court. Hearing this information—though with no particular
reason to think it was Chris that Jane saw—I utter (6)/(7):
(6)
If Chris injured himself horribly on the tennis court, then I regret that
I ever taught him how to play.
(7)
If Chris injured himself horribly on the tennis court, then I hope that
he won’t blame me for his injuries.
Both (6) and (7) are acceptable in the context of Tennis, but suppose that
unbeknownst to Jane or me (8) is true:
3
(8)
Chris injured himself horribly on the tennis court.
(9) and (10) then seem to follow by modus ponens:
(9)
(10)
I regret that I ever taught Chris how to play.
I hope that Chris won’t blame me for his injuries.
However, once again it is hard to see how either report could be true, since I
seem to have no evidence that anything untoward has happened to Chris. Also,
if it is shared knowledge that Chris always plays tennis in a secluded area with
Andrew, who tends to panic in emergencies, we can say things like (11):
(11)
If Chris injured himself on the tennis court, then I regret that Andrew
is the one who knows it.
As before, the consequent of (11) appears to be contradictory on standard semantics for attitude verbs, yet the conditional remains perfectly acceptable.
A similar phenomenon arises with doxastic verbs like ‘think’ and ‘suspect’.
Consider (12) in the context of Bill’s Holiday, and (13) in the context Tennis:
(12)
If Bill is on a plane to Cuba, then I suspect that he is traveling first-class.
(13)
If Chris injured himself on the tennis court, then I think that Andrew
is panicking right now.
Each conditional has a true reading in their respective contexts. However, if
Bill really is on a plane to Cuba then it doesn’t seem to follow that I suspect
he is traveling first class. Similarly, if Chris really did injure himself, it doesn’t
seem to follow that I believe Andrew is panicking.
The puzzle also arises in constructions other than conditionals. Consider the
following scenario, as well as the disjunctions that follow it:
Party: I have been looking forward to Ted’s party for a while, and
expect a lot of people to be there. However, upon arriving I only see
a handful of people milling around the drinks table. Then I say:
(14)
Either a lot of people are on the deck outside, or I’m surprised that there
are so few people here.
(15)
Either a lot of people are on the deck outside, or I regret that I didn’t
bring more friends.
4
(16)
Either a lot of people are on the deck outside, or I think I should have
stayed at home.
(14)-(16) are acceptable in context, and raise similar issues to the conditionals
above. If there aren’t a lot of people on the deck outside then, e.g. ‘I’m surprised
that there are so few people here’ follows from (14) by disjunctive syllogism. But
intuitively it is a live possibility for me that there are a lot of people outside, in
which case I do not know that there are few people at the party. So we have a
case in which disjunctive syllogism seems to lead from true premises to a false
conclusion.
Where Φ is an attitude verb, we will call sentences of the form ‘If P, then S Φs
that Q’ attitude conditionals. Each of the conditionals we have considered so far
is an attitude conditional. We will call the subclass of attitude conditionals that
appear to entail sentences of the form ‘If P, then S Φs that (P and S doesn’t
know that P)’ Fitch conditionals.3 (4), (5), and (11) are all Fitch conditionals.
We will also call sentences of the form ‘Either P, or S Φs that Q’ attitude
disjunctions. Finally, we will call the class comprised of attitude conditionals
and attitude disjunctions attitude constructions.
The puzzles raised above show that an explanation of what is happening
with attitude constructions is in order. This paper’s aim is consider some of
the difficulties involved in offering a systematic explanation, but also to try
to develop the approach we find most promising. The view we defend is that
the epistemic and doxastic bases that feature in the denotations of attitude
verbs are sometimes intersected with, or restricted by, a given proposition. For
instance, on the natural reading of (1), ‘surprise’ as it appears in the consequent
is restricted by the proposition expressed by the antecedent of the conditional,
namely that Bill is on a plane to Cuba. We show how this resolves the puzzles
introduced above. However, this response also raises further issues that are
less easily addressed, the most important of which is how these restrictions
get determined in each case. We show that there are challenges to providing a
satisfying answer to this question. Indeed, our inquiry will ultimately raise more
questions than it answers. Nevertheless, we hope to open up an interesting area
for future research.4
3 The name is suggested by the ‘paradox of knowability’ that was discovered in response to
the work of Frederic Fitch (Brogaard & Salerno, 2013). The paradox features claims of the
form ‘It is possible that S knows that (P and S does not know that P)’.
4 As far as we are aware, Drucker (2017) and Jerzak (forthcoming) are the only other
theorists who have explicitly discussed attitude conditionals and some of the problems that
5
The paper is structured as follows. In §2 we argue against the view that
scopal ambiguities explain the behavior of attitude constructions. In §3 we put
forward our preferred approach to the puzzles of §1: the view that attitude verbs
sometimes exhibit restricted readings. We explain how appealing to restriction
vindicates our intuitions about attitude constructions as well as the validity
of, e.g., modus ponens. §§4-5 formulate and motivate two conditions on the
availability of restrictions. The first condition connects the availability of nontrivial restriction to the dynamic properties of the logical connectives. The
second puts constraints on the subject term of the report, as well as the tense
of the attitude verb. Then in §6 we consider some data that seem to pose a
problem for the conditions presented in the previous sections. §7 draws some
morals for future semantic theorizing, while §8 concludes.
2
Wide-scoping
We begin with a relatively conservative response to the puzzles raised by attitude
constructions. This response tries to explain the data in terms of scope. The
idea, roughly, is that a sentence whose surface form is ‘If P, then S Φs that Q’
or ‘Either P, or S Φs that Q’ is ambiguous between two readings, whose logical
forms we can represent as follows:
(17)
a. If P, then (S Φs that Q).
they raise. Drucker appeals to attitude conditionals such as (6) and (7) in the course of
arguing for a certain type of radical externalism about non-doxastic attitudes. He accepts
modus ponens and takes these conditionals at face value, concluding that the facts about
our attitudes of, e.g., regret can be deeply external to us. Drucker does not discuss attitude
disjunctions, Fitch conditionals, or attitude conditionals featuring verbs other than emotives.
Indeed, it is important for Drucker’s arguments that there not be comparable conditionals
with doxastics, and thus data such as (12) and (13) pose a problem for the view he defends
(p.8). Moreover, Drucker’s general approach cannot handle Fitch conditionals, and it doesn’t
carry over to the data presented in §6 concerning, e.g. ‘know’.
As for Jerzak, he is primarily concerned with attitude conditionals that feature ‘want’ (see
§6 for a discussion of some of Jerzak’s data). He provides a semantics for ‘want’ that is “information sensitive”: want reports depend for their interpretation on a shiftable information
state parameter. Jerzak does not consider attitude disjunctions, Fitch conditionals, or attitude constructions involving factive verbs. He does explicitly discuss attitude conditionals
featuring ‘believe’, but argues that the attitude verb should be interpreted “wide-scope” with
respect to the conditional Jerzak (forthcoming, 10). See §2 for further discussion of this response and some problems with it. We do not have the space to consider Jerzak’s semantics
in detail here. But it is worth noting that we are sympathetic to some of the central aspects of
Jerzak’s approach, namely that that ‘want’ is sometimes subject to restriction effects. However, it is not clear to us how the account could be carried over to other verbs, e.g. factives
and doxastics. So, in short: although Drucker and Jerzak discuss attitude constructions and
make a number of insightful observations about their properties, our examination is more
detailed, and our perspective on their significance is different.
6
b. S Φs that (if P, then Q).
(18)
a. Either P, or (S Φs that Q).
b. S Φs that (either P, or Q).
(17a)-(18a) represent the “narrow-scope” reading of the conditional/disjunction,
on which the attitude verb Φ takes scope only over Q. (17b)-(18b) represent the
“wide-scope” reading, on which the verb takes scope over the entire conditional
‘If P, then Q’ or disjunction ‘Either P, or Q’.
One might think that resolving this ambiguity will help with our puzzles. For
instance, it might be maintained that (12) (‘If Bill is on a plane to Cuba, then I
suspect that he is traveling first-class’) should be read wide-scope, and that its
logical form can be more perspicuously expressed by (19):
(19)
I suspect that: if Bill is on a plane to Cuba, then he is traveling firstclass.
‘I suspect that Bill is traveling first-class’ does not follow from the conjunction
of (12) and (2) (‘Bill is on a plane to Cuba’), so this move does block the
problematic inference.
However, there are a number of problems with this response. For one, some
attitude constructions are simply not amenable to it. Consider (20):
(20)
If Bill is on a plane to Cuba, then the person who I think he’s traveling
with is Mary.
Relative clauses are usually taken to be “scope islands” for movement, which
means that it is unclear how ‘think’ could take wider scope than the conditional
(May, 1985). But (20) raises all the same worries as the other examples under
consideration.
For another, even when a wide-scope interpretation is available, it often fails
to provide the right reading of the relevant attitude construction. Consider (21):
(21)
If Bill is on a plane to Cuba, then he is traveling first class and I suspect
that he is drinking champagne.
(21) is assertable only if I am sure that Bill is traveling first class, given that he
is on a plane to Cuba; but ‘I suspect that: if Bill is on a plane to Cuba, then he
is traveling first-class and drinking champagne’ is assertable even when I have
7
only a suspicion that Bill is traveling first class, given that he is on a plane to
Cuba. So, these two sentences don’t seem to have the same meaning.5
A related problem is brought out by attitude constructions like (1) (‘If Bill is
on a plane to Cuba, then I am surprised that he left without saying goodbye’):
if this is read wide-scope, then its logical form can be represented by (22):
(22)
I am surprised that: if Bill is on a plane to Cuba, then he left without
saying goodbye.
The trouble is that (22) is not only false, but obviously so. It is not in the
least bit surprising that if Bill is on a plane to Cuba, then he left without
saying goodbye. At no point since Bill missed his chance to say goodbye has
my evidence favored the proposition that if Bill is on a plane to Cuba, then he
did say goodbye before leaving. This proposition is thus not something I could
find surprising.
Finally, as Drucker (2017, 13) notes, attitude conditionals in which the argument to the verb is a propositional anaphor raise a particularly sharp challenge
to the wide-scope response:
(23)
If Bill is on a plane to Cuba, then that surprises me.
Granted the plausible assumption that the semantic contribution of ‘that’ in
(23) is the proposition expressed by the antecedent, the wide-scope reading of
(23) is equivalent to (24):
(24)
I am surprised that: if Bill is on a plane to Cuba, then Bill is on a plane
to Cuba.
This is clearly not the intended reading of (23). Although many things may
surprise me, the tautology that if Bill is on a plane to Cuba, then he is on a
plane to Cuba is not one of them.
The same points apply mutatis mutandis to the wide-scope interpretations of
the Fitch conditionals and attitude disjunctions from §1. We conclude that a
different style of explanation is called for.6
5 Thanks to an anonymous reviewer for suggesting examples like (20) and (21). The reviewer
also notes that examples analogous to (21) are used by Yalcin (2012) in arguments concerning
the scope of embedded probability operators.
6 Drucker (2017, 13-14) considers a different response on which attitude conditionals like
‘If P, then S Φs that Q’ are systematically reinterpreted along the lines of: ‘If S finds out
that P, then S will Φ that Q’. We find Drucker’s objections to this reply compelling. Among

Restriction
We suspect that the puzzling behavior of the attitude constructions in §1 is due
to the semantics of their attitude verbs, rather than, e.g. the syntactic properties of attitude constructions. Indeed, the existence of Fitch conditionals is
itself strong prima facie reason to suspect that the puzzle arises there. Fitch
conditionals do not have the semantic phenomenology of conditionals with contradictory consequents. But if the verbs that appear in their consequents were
to be interpreted uniformly, it would be difficult to explain why this is so. Thus,
we favor the strategy of positing a multiplicity of readings for attitude verbs.
In particular, we argue that attitude verbs can take their “normal” readings
as well as a range of (soon to be specified) “special” readings, readings whose
existence explains the puzzling behavior of attitude constructions.
By positing a multiplicity of readings we get a straightforward defense of the
validity of, e.g., modus ponens. The idea is just that the “counterexamples”
to the inference rules that we considered in §1 equivocate. For instance, (1)
(‘If Bill is on a plane to Cuba, then I am surprised that he has left without
saying goodbye’) is true on its most natural interpretation because ‘surprise’
as it appears in the consequent takes a special reading. In contrast, (3) (‘I am
surprised that Bill has left without saying goodbye’) is false on its most natural
interpretation because ‘surprise’ as it appears here, i.e. when the report is
unembedded, tends to take a normal reading. But holding readings fixed—that
is, keeping things uniformly special or uniformly normal—the inference is valid:
if (1) and (2) are both true, (3) must be true as well. It’s just that we tend not
to hold readings fixed when arguments like these are considered. Similarly for
arguments involving (14) (‘Either a lot of people are on the deck outside, or I’m
surprised that there are so few people here’) using disjunctive syllogism.
As for Fitch conditionals such as (5) (‘If Bill is on a plane to Cuba, then I
am surprised that he has departed without my knowing’), the idea is that their
natural interpretations are ones on which the wide-scope verbs, e.g. ‘surprise’,
other things, he points out that “deathbed sentences” like (25) are inhospitable to the reinterpretation strategy:
(25)
If this is the last thought I have before dying, then I’m glad it’s such a philosophical
one.
We concur, and add that attitude conditionals like the following prove similarly difficult:
(26)
If Bill’s on a plane to Cuba but has made sure that I never find out about it, then I
am surprised that he is so secretive.
9
take special readings while the narrow-scope verbs, e.g. ‘know’, take normal
readings. On these interpretations, a Fitch conditional’s consequent is noncontradictory, vindicating the intuition that Fitch conditionals are coherent.
We will develop these ideas more explicitly over the course of this section. But
before we do we want to be explicit about our aims at this point in the paper.
Our response to the puzzles of §1 outlined directly above brings with it two
important questions: (a) what, semantically, is the difference between normal
and special readings, i.e. what do the entries for attitude verbs need to look like
in order for them to take both kinds of readings?; and (b) when are the special
readings available, and what determines their content? In this section, we only
try to answer question (a). §§4-6 are devoted to trying to answer question (b),
which is more challenging.
3.1
Restricted belief
Due to its simplicity we begin with an account of the special readings of the
verb ‘believe’. We turn to more complicated verbs like ‘regret’ once the basic
machinery is in place.
Let us suppose that for any given belief state, there is a unique, maximal set
of possible worlds consistent with it. More concretely, let us say that for any
subject S and world w , Doxw,S is the maximal set of worlds compatible with
what S believes in w —i.e. S ’s belief set in w (Hintikka, 1962). The orthodox
semantics for ‘believe’ can be presented as follows (‘p’ denotes the proposition
expressed by P):
(27)
Standard semantics for ‘believe’
‘S believes that P’ is true at w iff: Doxw,S ⊆ p.
Now we introduce a mechanism that, when applied to a set of possibilities,
will allow us to produce a (possibly strict) subset of those possibilities. We
will call this mechanism restriction. A restriction † is a set of worlds, i.e. a
proposition. A restriction can be used to winnow down a set of possibilities via
set intersection. We allow restrictions to have a semantic effect by enriching our
points of evaluation with a propositional parameter:
(28)
Restricted semantics for ‘believe’
‘S believes that P’ is true at w under restriction † iff: (Doxw,S ∩ †) ⊆ p.
10
To illustrate, suppose that John’s belief state at w1 can be represented by three
worlds: Doxw1 ,John = {w1 , w2 , w3 }, and that the proposition A = {w1 , w4 }.
Suppose also that Bill is in Costa Rica in w1 , and the United States in w2 and
w3 . Given (28), ‘John believes that Bill is in Costa Rica’ is true at w1 under A iff
(Doxw1 ,John ∩ A) ⊆ {w | Bill is in Costa Rica at w}. Since (Doxw1 ,John ∩ A) =
{w1 } and {w1 } ⊆ {w | Bill is in Costa Rica at w}, it follows that (Doxw1 ,John ∩
A) ⊆ {w | Bill is in Costa Rica at w} . So, the report is true at w1 under the
restriction A.7
Note that the standard semantics for ‘believe’ may be straightforwardly recovered from the restriction semantics. This is because whenever † is the trivial
restriction ⊤—the set of all worlds—it follows that for any subject S , and world
w : Doxw,S ∩ ⊤ = Doxw,S . Thus, from the perspective of the restricted account,
the reading of ‘believe’ posited by the standard account is just that in which
the restriction is the tautology.
Before explaining how the restriction semantics can account for ➜1’s doxastic
attitude constructions, it will be helpful to introduce a shorthand for referring
to the various readings induced by restriction. We will enrich our metalanguage
as follows. Where † is a restriction, we will call Doxw,S ∩ † the set that is
determined by S ’s beliefs † (at w ). Accordingly, if (Doxw,S ∩ †) ⊆ p, then we
will say that S believes † that P (at w ). Given the observation above, when
the trivial restriction is in play we will speak interchangeably of believing and
believing ⊤ .
To reiterate, our goal here is to give an explicit account of how special and
normal readings work, not how special and normal readings get determined. So
at this point we will just help ourselves to the relevant restrictions and show how
our restricted semantics generates the desired readings. With that in mind, let
I be the proposition that Chris injured himself on the tennis court. The natural
readings of (13) (If Chris injured himself on the tennis court, then I think that
Andrew is panicking right now’) and ‘I think that Andrew is panicking right
now’ (i.e. the consequent of (13) as it occurs unembedded) can be represented
as follows:
(29)
I think⊤ that Andrew is panicking right now.
7 For simplicity, we will assume that restrictions are not derived from more complex objects, e.g. as the intersection of a “modal base” (Kratzer, 1986), or the output of a question
denotation given a relevant world. However, see fn.33 for further discussion of the latter
option.
11
(30)
If Chris injured himself on the tennis court, then I thinkI that Andrew
is panicking right now.
Since think⊤ is just normal belief, and since I definitely do not believe in
anything like the normal sense that Andrew is panicking, ‘I think that Andrew
is panicking right now’ is false in Tennis when the constraint is ⊤.8 Thus, the
unembedded report is false on its natural reading, just as we want.
As for (13), given that Chris did actually injure himself at w@ (the actual
world), its semantic value hangs on whether ‘I think that Andrew is panicking
right now’ is true at w@ under the restriction I. This is indeed the case, since
every world in Doxw@ ,Me in which Chris injured himself is one where Andrew
panics. That is, the set of possibilities corresponding to the intersection of all
that I think⊤ with the proposition that Chris injured himself on the tennis court
is a subset of the set of possibilities in which Andrew is panicking right now.
Hence, (13) is true on its most natural reading.
To sum up, we maintain that it is the non-uniformity of restriction in the
natural interpretations of embedded and unembedded attitude reports that explains our seemingly inconsistent intuitions about attitude constructions featuring doxastics. The remainder of the section will offer a similar analysis of
‘know’ and ‘regret’. This will help to illustrate how the restriction account can
be applied more generally.
3.2
Factive verbs and (restricted) knowledge
‘Regret’ is a so-called “factive” attitude verb (Giannakidou, 2006). We will
assume the following about factive verbs:
k-entailing: Where Φ is a factive attitude verb: if ‘S Φs that P’
is true, then ‘S knows that P’ is true.9
k-entailing was already alluded to in the presentation of the puzzles in §1.
For instance, we argued that part of the reason to think (3) (‘I am surprised
8 We assume harmlessly that ‘believe’ and ‘think’ are semantically equivalent (cf.
Hawthorne et al. (2016)).
9 See (Williamson, 2000, ch. 1) for arguments in support of this principle. Egré (2008)
maintains that factives are only “belief entailing” so that, e.g. ‘S regrets that P’ only entails ‘S
believes that P’. Those who follow him in this are welcome to weaken k-entailing accordingly,
for this will make no difference to our central arguments. Also, those who think that factivity
is best captured as a presupposition rather than an entailment are welcome to substitute
“undefined” for “false” in the relevant arguments. Again, this will make no difference to the
central claims of the paper.
12
that Bill left without saying goodbye’) is false is that, intuitively, I don’t know
that Bill has left without saying goodbye, so I can’t be surprised that he left
without saying goodbye either.
We endorse k-entailing and intend to defend a restriction-based semantics
for factives like ‘regret’. But this raises an issue: we know that the subjects of
our various attitude constructions lack anything resembling normal knowledge of
the propositions expressed by the complement clauses of the embedded reports.
It follows that we need a semantics for ‘know’ that makes it amenable to the
phenomenon of restriction too. Let us stipulate that for any subject S and
world w , Epiw,S is the maximal set of worlds compatible with what S knows in
w —i.e. S ’s knowledge set in w . Here are the standard and restricted entries for
‘know’:
(31)
Standard semantics for ‘know’
‘S knows that P’ is true at w iff: Epiw,S ⊆ p.
(32)
Restricted semantics for ‘know’
‘S knows that P’ is true at w under restriction † iff: (Epiw,S ∩ †) ⊆ p.10
With these entries for ‘know’ in place, we can speak meaningfully of what a
subject knows† , and thus make use of restricted knowledge in giving a semantics
for verbs like ‘regret’. We should be clear, however, that the motivation for our
restricted semantics for ‘know’ goes beyond the fact that it is required by the
conjunction of k-entailing and our semantics for emotive factive verbs like
‘regret’. As we will see in §6, there are a variety of attitude constructions
involving ‘know’ that tell in favor of a semantics along the lines of (32). But as
we will also see in §6, this data is far more unruly than the data involving the
other attitude verbs that we have considered so far. We thus postpone the task
of offering direct motivation for (32) until later in the paper.
10 It is worth noting that Schaffer & Szabo (2013) give an entry for ‘know’ on which it is
essentially modeled as an adverb of quantification (like ‘usually’ or ‘might’). In particular,
they allow the modal base that ‘know’ quantifies over to be restricted by the antecedent of
a conditional. However, when discussing attitude conditionals featuring ‘know’, Schaffer &
Szabo, (pp.528-30) maintain that ‘know’ takes wide-scope over the conditional. So, although
their semantics allows for restriction effects, they do not make use of it in solving the problems
posed by attitude constructions.
13
3.3
Restricted regret
For simplicity, we will take our baseline semantics for ‘regret’ to be Heim’s (1992)
comparative desirability account.11 The rough idea behind Heim’s theory is that
regretting something is a matter of knowing it, but also wishing it weren’t so.
A bit more formally:
(33)
Heim-style standard semantics for ‘regret’
‘S regrets that P’ is true at w iff: (i) S knows p at w and (ii) for most
worlds w′ compatible with what S knows at w : S prefers (at w ) the
worlds most similar to w′ in which ¬p, to w′ .12
Thus, ‘John regrets that Bill failed the exam’ is true at w iff (i) John knows
that Bill failed the exam, and (ii) for most worlds w′ compatible with John’s
knowledge: John prefers each world most similar to w′ in which Bill did not fail
the exam, to w′ .13
To handle the attitude constructions of §1 that feature ‘regret’, we enrich
Heim’s entry with restriction:
(34)
Restricted semantics for ‘regret’
‘S regrets that P’ is true at w under † iff: (i) S knows† p at w and (ii)
for most worlds w′ compatible with what S knows† at w : S prefers (at
w ) the worlds most similar to w′ in which ¬p, to w′ .
11 We could just as easily have used an “ideal worlds” analysis (von Fintel, 1999), but a
Heim-style account is more economical for our purposes. Strictly speaking, Heim does not
explicitly provide an entry for ‘regret’, but it is easy to see what she intends given her treatment
of ‘glad’.
12 Two remarks about this entry are in order. First, by assuming Strong Centering, i.e.
that if w is a p-world, then the closest p-world to w is w itself (Lewis, 1973), we are able to
simplify condition (ii) from what Heim has, which officially is ‘....S prefers (at w ) the worlds
most similar to w′ in which ¬p, to the worlds most similar to w′ in which p’ (although Heim
does suggest that such a simplification is plausible). Second, the analog of (ii) in Heim’s entries
for desire-based verbs quantifies universally over S ’s knowledge set, whereas our entry checks
only to see whether a majority of the worlds in S ’s knowledge set meet the relevant condition.
A Heim-style condition makes the problematic prediction that if it’s an epistemic possibility
that your lottery ticket will turn out to be a winner, then absent bizarre preferences against
winning lots of money, you can’t regret buying it. That said, neither (ii) nor the standard
Heimian truth-conditions can capture so-called ‘insurance’ cases: ‘I regret that I didn’t buy
house insurance’ can be true even when it is quite likely on my evidence that nothing happens
to my house (Levinson, 2003). Levinson proposes a probabilistic semantics in response to these
cases. As far as we can tell, this semantics is compatible with the mechanism of restriction
that we posit, but we stick with something more straightforward.
13 The reason only the worlds closest to w ′ in which Bill did not fail the exam are considered
is that the report can be true even if John prefers some distant worlds in which Bill fails the
exam to w′ (e.g., worlds where all and only those who pass the exam are enslaved by cruel
aliens).
14
The natural readings of, e.g. (6) (‘If Chris injured himself horribly on the
tennis court, then I regret that I ever taught him how to play’) and (9) (‘I
regret that I ever taught him how to play’) can be represented as follows (recall
that I is the set of worlds in which Chris injured himself on the tennis court):
(35)
If Chris injured himself horribly on the tennis court, then I regretI that
I ever taught him how to play.
(36)
I regret⊤ that I ever taught Chris how to play.
It is straightforward to show that on the restrictions assigned above, (6) is true
but (9) is false. What is perhaps less obvious to see is how restriction helps us
make sense of the Fitch conditional (11) (‘If Chris injured himself on the tennis
court, then I regret that Andrew is the one who knows it’). Its most natural
reading can be represented as follows:
(37)
If Chris injured himself on the tennis court, then I regretI that Andrew
is the one who knows⊤ it.
That is, in order to handle (11) we assume that ‘regret’ and ‘know’ in the
consequent are evaluated under distinct restrictions: I and ⊤, respectively.
Given that Chris injured himself at w@ , this means that (11) is true at w@ iff
(i) at w@ I knowI that Andrew is the one who knows⊤ that Chris is injured
(i.e. for all w ∈ Epiw@ ,Me such that Chris injured himself in w, for all x except
Andrew: Epiw,x 6⊆ I), and (ii) for each w′ compatible with what I knowI at w@ :
I prefer the worlds most similar to w′ in which someone distinct from Andrew is
the only person who knows⊤ that Chris injured himself, to w′ . Condition (i) is
satisfied given my knowledge⊤ that Andrew and Chris play tennis in a secluded
area, i.e. my knowledge⊤ that if Chris was injured, only Andrew would know⊤
about it. Condition (ii) is also satisfied given my knowledge⊤ that Andrew tends
to panic in emergencies. So, (11) is true at w@ , as required.
Taking stock
We trust that the general form of the restriction strategy is now clear enough
to see how it could be applied to other kinds of attitude constructions. Thus,
one need not think that the puzzling behavior of attitude constructions is due
to the invalidity of inference rules like modus ponens or disjunctive syllogism.
Nor does one have to think that attitude constructions exhibit surprising syntactic properties. So long as one accepts that attitude verbs are subject to the
15
mechanism of restriction, one will have the resources to account for the natural readings of the data in ➜1 in a manner that is logically and syntactically
orthodox.
However, the picture is not complete, for we have not yet said when nontrivial restrictions take effect, or what determines their content when they do.
The second half of the paper is devoted to answering these questions. For
reasons that will emerge over the course of the discussion, we believe that the
issues involved here are of considerable complexity. But we also believe that
one of the main contributions of the first half of this paper is that we are now
in a position to understand these challenges more clearly.
In the following two sections, we formulate and motivate two conditions on
non-trivial restriction. Both conditions draw on the formal properties of attitude constructions to constrain the availability and content of the restriction.
The first condition connects the availability of non-trivial restriction to the
dynamic properties of conditionals, disjunctions, and conjunctions (§4). The
second puts constraints on the subject term of the report, as well as the tense of
the attitude verb (§5). We argue that taken together, these restrictions provide
a fairly satisfying picture of the data considered so far. (But to foreshadow
what will come in §6, it is unclear how robust these generalizations are once the
scope of the inquiry expands to attitude verbs such as ‘know’, ‘remember’, and
‘want’.)

Dynamic restriction
Recall that I is the set of worlds in which Chris injured himself on the tennis
court, and let D be the set of worlds in which there are not a lot of people on
the deck outside. We know that the (a) sentences take the (b) readings (in their
respective contexts).
(38)
a. If Chris injured himself horribly on the tennis court, then I regret
that I ever taught him how to play.
b. If Chris injured himself horribly on the tennis court, then I regretI
that I ever taught him how to play.
(39)
a. I regret that I ever taught Chris how to play.
b. I regret⊤ that I ever taught Chris how to play.
16
(40)
If Chris injured himself on the tennis court, then I regret that Andrew is the one who knows it.
If Chris injured himself on the tennis court, then I regretI that
Andrew is the one who knows⊤ it.
(41)a. a. Either a lot of people are on the deck outside, or I regret that I
didn’t bring more friends.
b. Either a lot of people are on the deck outside, or I regretD that I
didn’t bring more friends.
What we want to know is why. That is, we want to be able to predict that
when a regret report is embedded in a conditional or a disjunction, the relevant
epistemic base can be non-trivially restricted; but when it is unembedded, it
seems that it cannot be. Moreover, we want the embedded report to take
the right restriction, e.g. the proposition expressed by the antecedent of the
conditional in (38a), and the negation of the first disjunct in (41a). We also
want the restriction to be optional in order to handle the pattern of restrictions
that we find in Fitch conditionals like (40). We will argue that a natural way
of trying to achieve these results is by systematically tying restrictions to the
“dynamic” properties of sentential connectives. We spell this out below.
It is commonplace to find theorists maintaining that sentential connectives
have “dynamic effects”. The general thought can be illustrated through the
phenomenon of presupposition projection. Consider the following sentences:
(42)
a. John stopped smoking last week.
b. John started smoking last year and he stopped smoking last week.
c. If John started smoking last year, then he’s stopped smoking this
year.
d. Either John never smoked, or he stopped smoking this year.
(42a) carries the presupposition that John used to smoke. However, none of
(42b)-(42d) carry this presupposition. The standard explanation is that in each
case, the presupposition is (dynamically) “filtered” by earlier material in the
sentence. That is, the embedded, presupposition-carrying clause (‘John stopped
smoking’) is evaluated against a background that is provided by previous parts
of the relevant sentence. Since the presupposition that John used to smoke
is satisfied in this enriched background, the sentence as a whole presupposes
17
nothing. In (42b) this background is provided by the first conjunct, i.e. the
proposition that John started smoking last year; in (42c) it is provided by the
antecedent of the conditional (again the proposition that John started smoking
last year); and in (42d) it is provided by the negation of the first disjunct, i.e.
the proposition that it is not the case that John never smoked, i.e. that John
used to smoke.14
Though we wish to remain neutral on how exactly these dynamic effects
should be captured, and what exactly explains their presence, we believe that
something in the vicinity can be used to place substantive constraints on the
availability of non-trivial restriction. First, we assign clauses dynamic propositions as follows:
(43)
a. dynamic propositions
b. If π is a main clause, then π is assigned ⊤.
c. (i) If a conjunction ψ ∧ χ is assigned R, then ψ is assigned R and χ
is assigned R ∩ ❏ψ ❑
(ii) If a conditional ψ → χ is assigned R, then ψ is assigned R and
χ is assigned R ∩ ❏ψ ❑
(iii) If a disjunction ψ ∨ χ is assigned R, then ψ is assigned R and
χ is assigned R ∩ (⊤ − ❏ψ ❑)
Then we tie the possibility of non-trivial restriction to dynamic propositions:
(44)
dynamic restriction
Given a main clause π, and constituent ‘S Φs that P’ of π: Φ is nontrivially restricted by † only if † = the dynamic proposition assigned to
‘S Φs that P’.
In short, what dynamic restriction says is that if an attitude verb ever
takes a non-trivial restriction † (i.e. † 6= ⊤), then † must be equivalent to the
background for interpretation that is systematically provided by previous parts
of the sentence (as determined by the rule for the relevant connective).
14 There is an enormous literature on these sorts of dynamic effects and how they should
be modeled. The idea that the interpretation of presupposition-carrying constituents in a
sentence systematically depend on earlier material essentially goes back to Kartunnen (1974)
and Stalnaker (1974). This thought has been developed in both a semantic direction, e.g.
(Heim, 1982), (Beaver, 2001), and a pragmatic one, e.g. (Schlenker, 2009). Klinedinst &
Rothschild (2012) discuss such dynamic effects as they relate to a variety of constructions,
e.g. modals and adverbs of quantification.
18
Note that dynamic restriction only allows embedded reports to take nontrivially restricted readings, since only embedded clauses are assigned non-trivial
dynamic propositions (by (43b)). This explains why, e.g., (39a) (‘I regret that
I ever taught Chris to play tennis’) is unacceptable, for its ‘regret’ can only be
trivially restricted.
But things are different for embedded reports. For instance, by (ii) of (43c),
‘regret’ can be be restricted by I in (38a) (‘If Chris injured himself on the tennis
court, then I regret that I ever taught him how to play’). (38a) is true when
‘regret’ takes this restriction. A similar result is obtained in the case of (41a): if
‘regret’ is non-trivially restricted then, by (iii) of (43c), the restriction must be
D. (41a) is true when the verb takes this restriction. So, when ‘regret’ takes a
non-trivial constraint in (41a), the sentence is true. Thus, dynamic restriction goes some way in explaining why (38a) and (41a) take their respective
readings.
What about Fitch conditionals like (40) (‘If Chris injured himself on the tennis
court, then I regret that Andrew is the one who knows it’)? Here we appeal
to the fact that dynamic restriction provides only a necessary condition
on non-trivial restrictions, not a sufficient one. Even when attitude verbs are
embedded, they need not take restricted readings—non-trivial restrictions are
optional. This accounts for the pattern of restrictions that we find in Fitch
conditionals, e.g. (40): ‘surprise’ is non-trivially restricted but ‘know’ is not.15
Finally, it is worth observing that dynamic restriction makes a striking
prediction, namely that attitude constructions should exhibit order effects. For
example, it predicts that ‘S Φs that P’ must be the second disjunct in a disjunction if Φ is to take a non-trivial restricted reading. As far as we can tell
this prediction is indeed borne out by the data:
(46)
a. Either a lot of people are on the deck outside, or I’m surprised by
15 We do not want to oversell the optionality of restriction, however. As far as we can tell,
attitude constructions like (45) only have false readings:
(45)
?? If Bill is on a plane to Cuba, then although I don’t know that he left without saying
goodbye, I am surprised that he left without saying goodbye.
But all that is needed for (45) to have a true reading is for ‘know’ to take the trivial restriction
while ‘surprise’ takes a non-trivial restriction. So perhaps the following should be added as
an independent structural constraint on the workings of restriction: whenever two or more
attitude verbs take the same scope in a sentence, they must all take the same restriction (be
it trivial or non-trivial). Otherwise the restrictions may vary. Attitude conditionals like (45)
feature verbs that take the same scope; whereas Fitch conditionals feature verbs that vary in
scope. Hence the difference in the availability of the non-uniform readings.
19
how few people there are here.
b. Either I’m surprised by how few people there are here, or a lot of
people are on the deck outside.
(47)
a.
Either a lot of people are on the deck outside, or I regret that I
didn’t bring more friends.
b. ?? Either I regret that I didn’t bring more friends, or a lot of people
are on the deck outside.
This provides yet further support for a condition on restriction along the lines
of dynamic restriction.16,17
16 One concern with dynamic restriction is that the restrictions it makes available appear
to be too strong in some cases. Consider (48):
(48)
If Chris injured himself on the tennis court, then I regret that I ever taught him how
to play and I’m worried that he’ll never speak to me again.
Intuitively, the proposition that Chris injured himself (I ) is a more plausible restriction for
‘worried’ than the proposition that Chris injured himself and I regretI that I taught him how
to play. That is, it seems that we want to have available a weaker restriction than the one
that dynamic restriction generates. We won’t provide a full solution to this problem here,
but believe that it can be remedied by assigning clauses sequences of propositions, rather
than just propositions. If this is done in the right way, the proposition that Chris injured
himself will be a member of the sequence assigned to the ‘worry’ report in (48). One can then
allow attitude verbs to be optionally restricted by an element in the sequence which they are
assigned.
17 One might wonder why we have not tied the possibility of restriction to local contexts
(Kartunnen, 1974; Stalnaker, 1974; Heim, 1982; Schlenker, 2009). The idea would be the
following: if an attitude verb ever takes a non-trivial restriction †, then † must be equivalent
to the local context of the relevant report. This proposal is similar in spirit to dynamic
restriction, but has the effect of strengthening the content of the restriction from the relevant
dynamically supplied proposition to the intersection of that proposition and the global context
in which the utterance occurs.
One problem with this proposal stems from the fact that interlocutors may mutually presuppose something false. In this case, the context set will contain false information and can
lead to unwanted restricted readings. For instance, suppose that we all come to falsely believe
that Bill is on a plane to Cuba, and then start discussing how odd it is that he left so abruptly.
I say (49):
(49)
I am surprised that Bill left without saying goodbye.
(49) only has a false reading (since the complement is false). However, the local context for
the report C (i.e. the global context) contains false information that is not included in the
epistemic states of the interlocutors, namely that Bill is on a plane to Cuba. This means that
if ‘surprise’ in (49) is restricted by C, this will have a non-trivial effect. Specifically, it should
be possible for ‘surprise’ in (49) to take a reading on which it is restricted by the proposition
that Bill is on a plane to Cuba. But in that case, (49) should have a true reading, much in
the same way that (1) (‘If Bill is on a plane to Cuba, then I am surprised that he left without
saying goodbye’) has a true reading when ‘surprise’ in the consequent is restricted by the
proposition expressed by the antecedent. In short, identifying restrictions with local contexts
is problematic because the context set can potentially carry unwanted information. Thanks
to an anonymous reviewer for bringing out this worry with the proposal.

5
First-Present Restriction
So far we have discussed a condition that ties the possibility of non-trivial verb
restriction to the environment in which the relevant report is embedded. Now
we consider a condition that ties restrictions to the form of the attitude report
itself.
5.1
Motivating the condition
Attentive readers may have noticed that the attitude reports under consideration have invariably been stated in the present tense using a first-person pronoun. This is no coincidence. The phenomenon of verb restriction is in general
much easier to get when the attitude reports have these properties. Consider
speeches like the following:18
(50)
?? I’m sleepy and Bill believes I’m sleepy.
(51)
?? It’s raining and I was surprised it was going to rain today.19
If the only constraint on restriction was dynamic restriction, then (50) would
have a true reading so long as it is merely compatible with what Bill believes (in
the normal sense) that I am sleepy. But this is clearly not right. If we know that
for all Bill believes (in the normal sense) I am wide awake, then (50) seems only
to have false readings. Likewise for (51): given only dynamic restriction,
the mere compatibility of my past knowledge state with the proposition that
it would be raining today would be enough to make possible true, restricted
readings of (51). But it seems only to have false readings.
These asymmetries in person and tense and can be seen in conditional and
disjunctive attitude constructions as well.20 Note that the past and future tense
versions of (1) are unacceptable:
18 We also consider sentences of the form ‘P and S Φs that Q’ to be attitude constructions,
namely attitude conjunctions.
19 To be clear, (50)-(51) can have true readings. Our claim is only that these sentences
cannot be read like the other attitude constructions discussed so far.
20 Thus, one should not take (50)-(51) to show that the phenomenon of verb restriction
only arises in attitude conditionals and disjunctions. Notice as well that although (3) (‘I am
surprised that Bill left without saying goodbye’) is intuitively false in the context of Bill’s
Holiday, the following disjunction of conjunctions is intuitively true:
(52)
Either Bill is on a plane to Cuba and I’m surprised that he’s left without saying
goodbye, or he’s at home as expected and I’m happy that I’ll get to see him this
evening.
But (52) would be false if ‘surprise’ and ‘happy’ could only take their normal readings.
21
(53)
a. ?? If Bill is on a plane to Cuba, then I was surprised that he left
without saying goodbye.
b. ?? If Bill is on a plane to Cuba, then I will be surprised that he left
without saying goodbye.
(53a)-(53b) seem false, or at the very least unassertable. And to the extent that
we can get ourselves in a context where either seems true, such a context seems
inevitably to be one in which ‘surprise’ takes its normal reading. For instance, if
Bill is on a plane to Cuba and, e.g., (53b) is true, then it does seem to follow that
I will be surprised (in the normal sense) that he left without saying goodbye.
The same is true (mutatis mutandis) of (54)-(55) in the context of Party:
(54)
?? Either a lot of people are on the deck outside, or I was surprised that
there would be so few people here.
(55)
?? Either a lot of people are on the deck outside, or I will regret not
inviting more people.
In each case the disjunction either seems clearly false, or to be an expression of
uncertainty about which normal attitudes I have had or will have.
With regard to the issue of person, suppose we add the following detail to
Bill’s Holiday: we know that Amy, who is currently somewhere very far away,
is just like us with respect to her expectations about and knowledge of Bill’s
travel plans. In this context the following strike us as unassertable:
(56)
a. ?? If Bill is on a plane to Cuba, then Amy is surprised that he left
without saying goodbye.
b. ?? Either Bill is on a plane to Cuba, or Amy is pleased that he is
still at home.
Again, the inference in each case is that Amy has some special information
about Bill’s whereabouts. But since it’s part of the setup of the case that she
is as ignorant about his whereabouts as we are, (56a)-(56b) seem only to have
false readings.
We take the above observations to provide a strong prima facie case for the
following constraint on non-trivial restriction:
(57)
first-present (fp) restriction
If Φ is non-trivially restricted by † in ‘S Φs that P’, then S is a firstperson pronoun and Φ is in the present tense.
22
It seems to us difficult to deny that restricted readings of embedded attitude
verbs are easier to come by when they meet the requirements of fp restriction. However, unlike dynamic restriction—which for the kinds of verbs
considered so far in the paper seems to face few counterexamples—there are a variety of attitude constructions that make trouble for fp restriction. As such,
we are unsure whether fp restriction should be taken to be a full-blooded
constraint on the presence of non-trivial restriction, or merely a reliable generalization. The remainder of this section discusses two of these problematic cases,
as well as some possible defensive moves available to those who would like to
treat fp restriction as a genuine constraint on restriction.
5.2
Some problems for the condition
The first putative counterexample concerns “echoing” uses of attitude constructions.21 These arise when some subject, S, utters a present tense attitude construction in the first-person—say ‘If P, then I Φ that Q’—and then someone
who overhears S ’s speech echoes it in the third-person. So, for example: Amy
asserts (1) (‘If Bill is on a plane to Cuba, then I am surprised that he left without saying goodbye’); we overhear it; then one of us asserts (56a) (‘If Bill is on a
plane to Cuba, then Amy is surprised that he left without saying goodbye’). In
these circumstances (56a) seems mostly fine, even when it is also salient to us
that Amy’s evidence concerning Bill’s whereabouts is as impoverished as ours
is. This seems to provide evidence that third-personal attitude constructions
like (56a) sometimes take restricted readings, and thus that fp restriction
constraint is false.
The second putative counterexample, due to an anonymous reviewer, concerns
cases such as the following:
(58)
If Weyland Corporation’s earnings miss expectations, the stock price
will fall and our financial advisor is of the opinion that we should buy.
(59)
If the bell rings, then the person who Bob suspects is at the door is
Steve.
We share the reviewer’s judgment that these sentences can have true readings
even when (i) it is not assumed that the subject of the embedded report knows
21 Thanks to Harvey Lederman and an anonymous reviewer for bringing such cases to our
attention.
23
whether the antecedents of the conditionals are true, and (ii) it seems like such
knowledge should be required for the embedded belief report to be true. Moreover, the anti-wide-scoping arguments of §2 apply just as well to (58)-(59), so
it is not plausible in either case that the doxastic is taking scope over the entire
conditional. There is thus reason to think (58)-(59) exhibit the phenomenon of
restriction, and thus that fp restriction is not true in full generality.
We are not entirely sure what to make of echoing uses of attitude constructions, or conditionals such as (58)-(59). They may well be genuine counterexamples to fp restriction. But there are also things that can be said in defense
of the condition. Regarding echoing uses, it is worth observing that though one
can hear a conditional such as (56a) sounding okay in these circumstances, just
about any echoed speech can be made to sound okay, no matter its content. For
example: suppose Amy is not part of our conversation, but we have an audio
recording of her confidently uttering ‘I know Oswald didn’t shoot Kennedy’. If
delivered in the right way, an utterance of ‘Amy knows Oswald didn’t shoot
Kennedy’ would seem just fine. But it is clear that the function of the report
is “quasi-quotational”, rather than straightforwardly assertoric. Perhaps something similar is driving the acceptability judgments involving echoing uses of
third-personal attitude constructions.
As for the third-personal doxastic attitude conditionals such as (58) and (59),
they seem to bear a similarity to the phenomenon of so-called “ultra-liberal” de
re attitude reporting (Pryor 2004; Recanati 2012; Blumberg & Holguı́n 2018).
This is when a subject who holds the purely general belief that all Fs are G can,
in some contexts, be appropriately ascribed the particular belief that o is G, for
some o that is in fact F. Importantly, this can happen even when it is known to
the ascriber that, intuitively speaking, the subject of the report does not know
that o is F, or even that o exists. For a concrete example of the phenomenon,
consider (60) in the following scenario:
Coach: Ann is a six-year-old girl whom Pete, an expert in tennis
pedagogy, has never met and whose existence he is unaware of. Pete
believes that every six-year-old can learn to play tennis in ten lessons.
Jane, Ann’s aunt, is aware of Pete’s feelings on the matter. Jane
wants to encourage Ann’s father, Jim, to sign Ann up for tennis
lessons, so in conversation with Jim she asserts the following:
24
(60)
Pete believes Ann can learn to play tennis in ten lessons.22
Ultra-liberal reports have not received much attention in the literature, and to
the extent that they have, most all of it has been focused on their unembedded
uses. But ultra-liberal attitude reports also have embedded uses. For instance:
suppose we don’t know whether Ann is a six-year-old, but we do know that Pete
believes all six-year-olds can learn to play tennis in ten lessons. We could then
assert:
(61)
If Ann is six years old, then Pete believes that she can learn to play
tennis in ten lessons.
What is the significance of ultra-liberal attitude reporting as regards thirdpersonal doxastic attitude constructions like (58) and (59), and fp restriction? Here are two hypotheses about the relationship between ultra-liberalism
and restriction: (i) the former is just an instance of the latter; or (ii) the phenomena are fundamentally distinct. If (i) holds, then given the acceptability of
third-personal ultra-liberal reports like (60) and (61), fp restriction is inadequate as a general constraint on the availability of non-trivial restriction—at
least for doxastic attitude constructions. In fact, the acceptability of unembedded ultra-liberal attitude reports like (60) would then be a problem for dynamic
restriction as well. On the other hand, if (ii) holds, constructions such as (58)
and (59) pose a problem for fp restriction only if they involve restriction,
and are not instances of (embedded) ultra-liberalism.
Though we lack the space to give the issue the full attention it deserves, we
believe there are some prima facie considerations in favor of (ii), the thesis that
ultra-liberalism and restriction are actually distinct phenomena. One consideration is that an ultra-liberal report like (60) can be acceptable even when it
is known to us, for reasons better or worse, that Pete is sure that Ann is a
five-year-old (but still holds the belief that all six-year-olds can learn to play
tennis in ten lessons). If in circumstances such as these we were to try to restrict
Pete’s belief set by the proposition that Ann is a six-year-old, the result would
be the empty set. It would then hold trivially that for any proposition, every
world in Pete’s restricted belief set would be one in which that proposition is
true. As such, we would expect any belief ascription with Pete as subject to be
acceptable since it will be trivially true, e.g. ‘Pete believes no six-year-old can
learn to play tennis in ten lessons’. Clearly this is not what we find.
22 This
example is essentially from (Recanati, 2012, p.152).
25
Another consideration against identifying ultra-liberalism with restriction is
that it is significantly harder to find acceptable ultra-liberal reports involving
factive attitude verbs. Even if we know that Pete knows that no two-year-old
can learn to play tennis in ten lessons, unless we have reason to believe that Pete
also knows our friend’s two-year-old Little Jimmy’s age, it is hard to hear a true
reading of the relevant ultra-liberal knowledge report. By contrast, restriction
does not seem to discriminate between factive and non-factive attitude verbs.
So, supposing we take these arguments to show that ultra-liberalism and restriction are indeed distinct phenomena, the argument against fp restriction
from (58) and (59) is sound only if they are instances of the latter rather than
the former. But there is a straightforward story on which this is not the case.
Let us focus on (58) (‘If Weyland Corporation’s earning miss expectations, the
stock price will fall and our financial advisor is of the opinion that we should
buy’). It is natural to suppose that our financial advisor holds a general belief
to the effect that one should buy stock in any company that bears the rough
financial profile of Weyland Corporation and misses expectations. But since we
don’t know whether Weyland Corporation will miss expectations, we can’t yet
say that our advisor thinks we should buy. Still, we can say that if it misses expectations, then our advisor thinks we should buy. Hence (58).23 Importantly,
however, if we were to discover that Weyland Corporation in fact missed expectations, we would be able to felicitously assert ‘Our financial advisor thinks
we should buy’ outright—even if we knew that our financial advisor had no
idea whether Weyland Corporation had in fact missed expectations. (58) thus
appears to have many of the hallmarks of an embedded ultra-liberal attitude
report.
Taking stock
Setting aside these points against echoing uses of attitude constructions and
conditionals such as (58) and (59), we do not want to oversell our position
here. We are attracted to fp restriction for a wide variety of attitude verbs,
and think there are moves that could to be made to explain away some of
the recalcitrant uses considered in this section. But we are reticent to claim
23 The
same points apply mutatis mutandis to (59). In this case we know Bob holds the
general belief that any door bell ringings (in the relevant location/timeframe) will be caused
by Steve.
26
anything stronger than that.24
In fact, we are now about to argue that there are other attitude constructions
that present decisive looking counterexamples to fp restriction, and thus
that it can’t be a general constraint on the availability of restriction. However,
we are also about to argue that these attitude constructions present equally
decisive looking counterexamples to dynamic restriction. So although it
might appear that this section’s tentative defense of fp restriction is in vain,
there is an interesting backup position that isn’t threatened by the next section’s
examples. It is the position that fp restriction and dynamic restriction
stand and fall together. That is to say, for certain attitude verbs, e.g. emotive
factives, non-trivial restriction requires the satisfaction of both fp restriction
and dynamic restriction, while for other attitude verbs neither is required.
It is ultimately out of interest in this thesis that we take seriously the question
of whether fp restriction is robust for the attitude verbs under consideration
so far.

Some (especially) puzzling cases
This section examines the embedding properties of evidential factives such as
‘know’ and ‘remember’, and the desire verb ‘want’. We argue that despite
the discussion in the previous sections, neither dynamic restriction nor fp
restriction seems to hold for these expressions. The question of what to make
of the apparent divergence in the availability of restricted readings between these
24 There is another potential class of counterexamples to fp restriction, albeit one that
requires only a (relatively) superficial revision of the condition. The basic idea is that the
proper form of the restriction isn’t to first-person subject terms, but to interlocutor -denoting
subject terms. Cases like the following are the motivation. Suppose Andrew and Jane are our
interlocutors in Bill’s Holiday, then (62)-(63) are felicitous:
(62)
[Gesturing towards Andrew] If Bill is on a plane to Cuba, then I bet you are also
surprised he left without saying goodbye.
(63)
If Bill is on a plane to Cuba, then I bet Jane also thinks that Bill didn’t tell any of us
he would be leaving.
However, barring echoing uses (63) is still unacceptable if Jane is far away and not part of our
conversation. If this is correct, then perhaps the relevant constraint should be formulated as
follows:
(64)
interlocutor-present restriction
If Φ is non-trivially restricted by † in ‘S Φs that P’, then S denotes an interlocutor
and Φ is in the present tense.
fp restriction would then just be a special instance of the broader condition on restriction.
27
verbs and the other verbs previously considered is then addressed in ➜7.
We will take evidential factives to be verbs like ‘know’, ‘remember’, ‘see’,
‘can hear’, and ‘can tell’.25 We believe they display the same sort of puzzling
behavior exhibited by the attitude constructions of ➜1. For instance, consider
the following case from Holguı́n (2018):
Memory Experiment: Joan and Megan are participating in a trial
of a drug whose primary effect is to swamp its subject with an extraordinary number of fake “memories” of the events of the past 24
hours. One of the subjects will get the drug, while the other will get
a placebo. Who gets which is determined by a coin-flip whose result
is known only to the experimenters.
During the experiment Joan and Megan are both (separately) asked
‘Do you remember what you ate for dinner yesterday?’ Joan appears
to remember that she ate fish; Megan appears to remember that she
ate spaghetti. As a matter of fact it was Joan who got the placebo
and Megan who got the drug. Only Joan’s memory is genuine.
Putting ourselves in Joan’s shoes, the following familiar looking attitude constructions are perfectly natural:
(65)
If I got the placebo, then I remember what I ate for dinner last night.
(66)
Either I got the drug, or I remember what I ate for dinner last night.
So to do the following less familiar ones:
(67)
I might remember what I ate for dinner last night; it depends on whether
I got the placebo or the drug.
(68)
One of us remembers what she ate for dinner last night.
And, strikingly, knowing that Joan got the placebo, the experimenters may
felicitously assert things like:
(69)
Joan remembers what she ate for dinner last night.
25 Like emotive factives, evidential factives are knowledge entailing (or presupposing). But
unlike emotive factives, the extra component is something evidential rather than emotive.
Where emotive factives convey the subject’s feelings about the known proposition, evidential
factives convey its etiology. We take ‘know’ to be an evidential factive whose evidential
component is trivial.
28
These uses of ‘remember’ seem to be puzzling in just the same way the uses of
‘surprise’, ‘regret’, ‘thinks’, etc., of ➜1 are. Intuitively Joan doesn’t know what
she had for dinner last night—at least not in anything like the normal sense of
‘know’—so it’s unclear how she could remember it in anything like the normal
sense either.26
The same phenomenon arises with ‘know’ itself (this case is also from Holguı́n
(2018)):
History Exam: Peggy and Pete are students in History 101. In
preparation for the multiple-choice final exam, both have purchased
and subsequently memorized answer sheets from their corrupt teaching assistant Roger. However, moments before the exam Roger
shares an unfortunate discovery: due to his ineptitude, one of Peggy
or Pete was given answers to an entirely different exam, and he
doesn’t know who it was. But he does know that the two answer
sheets happen to disagree on the answer to every single question.
Question 5 of the exam is: ‘In what year did the Berlin Wall fall?’
The possible answers are a: 1984, b: 1989, c:1991, and d: 1993.
Peggy’s answer sheet says b. Pete’s says c. Peggy is thus the one
with good answers.
Putting ourselves in Peggy’s shoes, the following familiar looking attitude constructions are perfectly natural:
(71)
If my answer sheet is good, then I know what the answer to question 5
is.
(72)
Either my answer sheet is bad, or I know what the answer to question
5 is.
So too are the less familiar ones:
(73)
I might know what the answer to question 5 is; it depends on whether I
got the good answers.
26 Evidence
that ‘remember’ is knowledge entailing is provided by the badness of conjunctions such as (70):
(70)
?? Although I don’t know what I had for dinner last night, I do remember what I had
for dinner last night.
29
(74)
One of us knows what the answer to question 5 is. (I hope it’s me.)
And supposing Roger the TA eventually discovers that it was Peggy who got
the good answers, it is fine for him to assert things like:
(75)
Peggy knows what the answer to question 5 is.
We hope the parallels between Memory Experiment and History Exam are
clear. By way of selling the claim that these uses of ‘know’ are non-standard
(and thus deserve special semantic treatment), note that, intuitively speaking,
Peggy’s credence that the answer to question 5 is b can be no higher than .5.
After all, Peggy is well aware that there’s only a .5 chance that she got the good
answers, and she’s certain that if she didn’t get the good answers then the answer
to question 5 isn’t b. To press the point further, notice that we can imagine
variants of the case on which Peggy’s credence that the answer to question 5 is
b is arbitrarily small. Just imagine, for instance, that there are 1,000 possible
answers to a given multiple choice question and that there are 1,000 different
students taking the test, each having purchased a different answer sheet from
Roger, and that one and only one of the students has the good answers, and that
Peggy knows all of this. Still, supposing Peggy is in fact the one with the good
answers (and that Roger eventually finds this out), all of (71)–(75) continue to
sound fine. So absent a highly non-standard interpretation of the technical term
‘credence’, (71)–(75) present counterexamples to the widely held view that ‘S
knows that P’ entails ‘S has a high credence in P’.27 We thus conclude that
whatever the semantic contribution of ‘know’ on the natural readings of any of
these sentences, it is not plausibly knowledge⊤ .28
27 See, e.g., Rothschild & Spectre (2016) for some applications of this principle. Note that
the principle can also be derived from the claim that ‘S knows that P’ entails ‘S believes
that P’, and the claim that ‘S believes that P’ entails ‘S has high credence that P’. These
principles are further orthodoxy, though see Hawthorne et al. (2016) for some reasons to doubt
the connection between belief and high credence.
28 In each of (65)–(69) and (71)–(75), ‘remember’ and ‘know’ take inquisitive complements
rather than declarative complements. This is because—for reasons that we lack the space
to explore here—analogous constructions with declarative complements tend to sound a bit
worse. Still, we will assume that in the context of Memory Experiment, ‘Joan remembers
what she ate for dinner last night’ entails ‘Joan remembers that she ate fish for dinner last
night’, and that in the context History Exam, ‘Peggy knows what the answer to question 5
is’ entails ‘Peggy knows that the answer to question 5 is b’. If these entailments didn’t hold,
then it would be difficult to explain the abominableness of the following conjunctions:
(76)
?? Joan remembers what she ate for dinner last night, but she doesn’t remember that
she ate fish for dinner last night.
(77)
?? Peggy knows what the answer to question 5 is, but she doesn’t know that the answer
to question 5 is b.
30
Finally, consider the following case involving ‘want’ adapted from Jerzak
(forthcoming):
Wine Time: You’ve been invited to a party and tasked with bringing
the wine. You know that the other guests have reasonably strong
preferences, but unfortunately you know basically nothing about
wine. At the grocery store you have a choice between a Pinot Noir
(from California) and a Malbec (from Argentina), which you take to
be equally likely to be the optimal choice for the other guests. As
such you think to yourself:
(78)
If they prefer wine from California, then I want the Pinot Noir.
(79)
Either they prefer wine from Argentina, or I want the Pinot Noir.
(80)
a. I might want the Pinot Noir; it depends on whether they prefer wines
from California or Argentina.
b. There’s a chance I want the Pinot Noir; it depends on whether they
prefer wines from California or Argentina.
And if an onlooker (somehow) knows of my situation and of the other guests’
actual preferences (suppose it’s for the Pinot Noir), she may think to herself:
(81)
That person wants to buy the Pinot Noir.
Although ‘want’ reports are not knowledge entailing, (78)-(81) are still intuitively puzzling. For instance, I have non-trivial credence that the other guests
have a preference for the Malbec, so it is difficult to see how (81) could be true.
Once again, the attitude verb appears to take a special reading here.
The hypothesis that ‘remember’, ‘know’ and ‘want’ take restricted readings in
their respective cases captures the data nicely. Take History Exam. Although
Peggy does not know⊤ that the answer to question 5 is b, there is a restriction,
G—the set of possible worlds in which Peggy has the good answers—such that
she knowsG that the answer to question 5 is b. This is because she knows⊤ that
either she has bad answers or the answer to question 5 is b. Thus (Epiw@ ,Peggy ∩
G) ⊆ {w | The answer to question 5 is b at w}. This means we can represent
the natural readings of, e.g. (71) and (75) as follows:
For further arguments in favor of these entailments, see Holguı́n (2018).
31
(82)
If my answer sheet is good, then I knowG what the answer to question
5 is.
(83)
Peggy knowsG what the answer to question 5 is.
The same can be said (mutatis mutandis) for the uses of ‘remember’ in Memory
Experiment and ‘want’ in Wine Time.29 We conclude that these cases provide
further support for the bare-boned restriction semantics of ➜3.
However, it should be clear that some of the cases above present striking
counterexamples to both fp restriction and dynamic restriction. We
will focus on History Exam to bring out the relevant points. With regard to
fp restriction, (75) is a straightforward counterexample to the first part,
since it is uttered by Roger (the TA) about a third-party (namely Peggy).
Counterexamples to the present part may be generated with ease too:
(84)
If I received the good answers, then I knew what the answer to question
5 was.
(85)
If I receive the good answers, then I will know what the answer to
question 5 is.
We can imagine Peggy uttering (84) after taking the exam, or (85) prior to
having received her answer sheet. In each case the sentence sounds perfectly
natural.30
As for dynamic restriction, all of (73)–(75) pose a problem for this principle, since none involve a conditional, disjunction, or conjunction. Instead, (73)
embeds its knowledge report in a modal, (74) embeds it under a quantifier, and
(75) is just the unembedded report itself. Indeed, (73)–(75) make clear the difficulty for any condition on restriction in the spirit of dynamic restriction:
the restriction effects witnessed by (73)–(75), if genuine, cannot be derived from
any of the formal features of the environments in which the embedded reports
occur. Instead, extra-linguistic features of the context must be called upon to
supply the relevant restrictions.
Finally, although the main aim of this section has been to show that there are
cases that pose a problem for dynamic restriction and fp restriction in
29 Supposing that we give ‘want’ a comparative desirability semantics similar to that given
to ‘regret’ in §3.3.
30 Note that the true readings of (84)–(85) are not those on which ‘know’ is forced to take
its normal interpretation. Peggy can utter (84) knowing⊤ full well that her past credence that
the answer to question 5 is b was no greater than .5.
32
the sense that these conditions are too strict, it is worth observing that there is
also a sense in which these conditions are not strict enough. And that is because
it is difficult to get acceptable restricted readings of ‘remember’ and ‘know’ in
“tautologous” attitude constructions of the form ‘If P, then I Φ whether P’ and
‘Either P, or I Φ whether not-P’. Consider, e.g.:
(86)
a. ?? If Bill is on a plane to Cuba, then I know whether he is.
b. ?? If Chris injured himself on the tennis court, then I remember
whether he did.
c. ?? Either a lot of people are on the deck outside, or I know whether
there aren’t.
The badness of these constructions is not predicted by either local restriction or fp restriction. It also marks an interesting contrast between evidential factives and emotive factives: as was pointed out in §2 with (23) (‘If Bill
is on a plane to Cuba, then that surprises me’), such conditionals are perfectly
felicitous.
However, we should not overstate the extent to which evidential factives
are unique here. Though emotive factive tautologous attitude constructions
sound fine, doxastic tautologous attitude constructions tend to sound somewhat
marginal (even if better than their evidential factive analogs):
(87)
a.
? If it’s raining, then I think it’s raining.
b.
? If Chris injured himself on the tennis court, then I’m sure he did.
These data suggest that the acceptability of tautologous attitude constructions
runs on a spectrum: on the one end there are evidential factives, which sound
mostly terrible; in the middle there are doxastics, which sound okay but not
great (though see Chalmers & Hájek (2007) for arguments that take the acceptability of these constructions for granted); and on the other end there are
emotive factives, which sound quite natural. What would explain this distribution is a question for further research.31
31 Note too that any explanation of these data will have to reckon with the fact that judgments here are extremely sensitive, in the following sense: evidential and doxastic tautologous
attitude constructions improve dramatically when of the form ‘If P, then I Φ that not-not-P’,
‘If P, then I Φ that P or (¬P and Q)’, etc.
33

7.1
Looking ahead
A semantic cleft?
What are we to do with these observations about evidential factives and ‘want’ ?
We see two ways of going forward, broadly construed. The first way is to take
the data just surveyed to be suggestive of a semantic cleft between different
categories of attitude verbs. This view grants that all attitude verbs take nontrivially restricted readings, but denies that the underlying mechanisms responsible for such readings is the same in each case. In favor of this view one could
cite the fact that restricting attention to, e.g. emotive factives, dynamic restriction and fp restriction both look quite robust (albeit the former more
so than the latter); by contrast, restricting attention to, e.g. evidential factives,
dynamic restriction and fp restriction both seem straightforwardly problematic.
We see this as an intriguing place for further research. But we note that it is
not without obvious theoretical drawbacks. Most plainly, it would be surprising
if the true account of verb restriction requires two independent mechanisms that
just happen to generate similar patterns of readings across categories of attitude
verbs. Also notice that no matter what account is given of, e.g. emotive factives,
the data surveyed in §6 suggests that the constraints on, e.g. ‘know’ will have to
be considerably complex. So, one will not be able to avoid positing theoretically
unwieldy restriction mechanisms just by countenancing a semantic cleft.32
32 Also note that the cleft will probably not be in keeping with existing taxonomies of
attitude verbs. For example: ‘hope’ seems to obey dynamic and fp restriction, despite the
fact that ‘want’ doesn’t. To see this, suppose you’ve already bought the bottle (either the
Pinot Noir or the Malbec) but you don’t know which one you bought. In this setting the
following thoughts seem natural:
(88)
a. If the guests prefer wine from California, then I hope I bought the Pinot Noir.
b. Either the guests prefer wine from Argentina, or I hope I bought the Pinot Noir.
So, ‘hope’ exhibits restriction effects (we already saw evidence of this in §1). But in keeping
with dynamic and fp restriction, it can only do so in the right linguistic environments:
(89)
a. ?? There’s a chance that I hope I got the Pinot Noir; it depends on whether they
prefer wine from California or Argentina.
b. ?? [Uttered by an onlooker:] That person hopes they bought the Pinot Noir.
c. ?? [Uttered by an onlooker:] If the guests prefer wine from California, then that
person hopes they bought the Pinot Noir.
Given the similarities between ‘hope’ and ‘want’, these observations come as something of a
surprise.
34
Alternatively, one might prefer to “generalize to the worst case” and posit a
single mechanism that accounts for the availability of restricted readings of all
attitude verbs. On an approach of this sort, one would enrich the semantics for
attitude verbs with a parameter for restriction—just in the way of ➜3’s entries
for ‘think’, ‘know’, and ‘regret’—but more or less leave it up to context to supply
its value. The task of accounting for the general (even if not entirely universal)
patterns of dynamic restriction and fp restriction would then have to
be treated separately.33
Overall, what seems clear to us is that a view comprised of dynamic restriction and fp restriction has a systematicity and elegance to it that
suggests it is worthy of further investigation; but also that there is enough recalcitrant data that other, less constrained alternatives should be on the table
too. As such, our goal has simply been to lay out some of the options in the
hopes of stimulating further research.
7.2
Other issues
We end this section by discussing two sets of issues naturally raised in light of
the central claims of the paper.
First, many theorists have maintained that epistemic modals exhibit restricted
readings.34 This naturally raises the question of the relationship between the
33 For reasons whose proper treatment is beyond the scope of the present discussion, we
believe that if dynamic restriction is abandoned, then the object that constrains the denotation of attitude verbs should be derived from a partition of logical space, i.e. from the
semantic value of a question. The restriction effect would then be achieved by intersecting, e.g.
Epiw,S (in the case of ‘know’) with the proposition that is the true answer to that question at
the relevant point of evaluation. (This will normally be the actual world, but on certain embedded uses—i.e. modals and conditionals—the point can shift to various non-actual worlds.)
The move to higher type is needed to account for the true readings of ascriptions like:
(90)
There is a 50% chance that I know what the answer to question 5 is.
If ‘know’ denotes knowledgeG , then (90) is false. After all, Peggy knows ⊤ that she knowsG
what the answer to question 5 is. However, if ‘know’ denotes knowledgeG? where G? is a
question along the lines of ‘Do I have the good answers?’, then we get the reading we want.
If Peggy’s answer sheet is good, then the restriction is the proposition that her answers are
good, and on that restriction she knows the answer to question 5. But if Peggy’s answer sheet
is bad, then the restriction is the proposition that her answers are not good, and on that
restriction she doesn’t know the answer to question 5. There’s only a 50% chance her answers
are good. Hence, there’s only a 50% chance the restriction is the proposition that her answers
are good. Thus, there’s only a 50% chance she knowsG? what the answer to question 5 is.
34 Some version of this idea is just about universally accepted in the literature on epistemic
modals. See, e.g., (Yalcin, 2007), (Gillies, 2010), (Kratzer, 2012), (Dorr & Hawthorne, 2013),
and (Moss, 2015) for a sampling of views that diverge on a number of matters on the semantics
of epistemic modality, but not on the fact that modals are sometimes subject to restriction-like
35
mechanism that generates restricted readings of verbs and the mechanism that
generates restricted readings of modals. A reasonable starting hypothesis is that
it is the same underlying mechanism, at least at some level of abstraction. But
supposing this hypothesis is correct, a number of questions present themselves.
For starters, what are we to make of Yalcin’s (2007) famous minimal pair?:
(91)
a. ?? If it is raining and it might not be raining, then...
b.
If it is raining and I don’t know that it is raining, then...
In particular, should we expect there to be infelicitous (restricted) readings of
sentences like (91b)?35 Additionally, if we are attracted to the view that doesn’t
posit a semantic cleft between the verbs that obey dynamic and fp restriction and those that don’t, then it looks like the workings of restriction cannot
in general be explained in terms of the formal properties of the constructions
in which restrictable expressions occur. Is that some reason to prefer theories of epistemic modals that explain their restriction effects in terms that are
fundamentally extra-linguistic?36
Second, there are important issues about the kinds of mental states attitude
verbs denote on their restricted readings. For instance: supposing the view
sketched in ➜3 is correct and we traffic in relations such as knowledge† in ordinary discourse, then we have reason to believe that ‘know’ sometimes denotes
relations that are in gross violation of, e.g., credence constraints on knowledge.
What, then, are the epistemological consequences of the availability of these relations in our talk of knowledge? Do cases like Memory Experiment and History
Exam present putative counterexamples to much of the orthodoxy about knowledge, or are certain resolutions of † privileged for the purposes of epistemological
theorizing?37 These questions deserve further investigation.
effects.
35 There is some evidence that we should. Consider:
(92)
? If Bill is in Cuba right now but I don’t know whether he is sleeping at home, then...
(93)
? If Federer will win Wimbledon but I don’t know whether he will win any slams,
then...
To our ears these conditionals sound quite bad. Putting things rather roughly, they have
the phenomenology as of being asked to suppose something and then to forget that one is
supposing it. The hypothesis that in each case ‘know’ takes a restricted reading would, if true,
be a nice explanation of these facts.
36 The similarities between the attitude construction data of ➜6 and some of the embedded
epistemic modal data of Dorr & Hawthorne (2013) and Moss (2015) could be taken as evidence
in favor of a positive answer to this question.
37 See Holguı́n (2018) for extended discussion of the epistemological issues raised by a semantics for ‘know’ along the lines presented in ➜3.

Conclusion
Our paper opened with a puzzle: certain ordinary uses of attitude verbs present
prima facie counterexamples to standard logical inference rules (e.g., modus ponens and disjunctive syllogism). We resolved the puzzle by positing restricted
readings of these verbs. We then turned to the task of finding mechanisms that
would explain when the restriction arises and what its content is when it does.
Our first attempt connected restriction to the dynamic effects of the connectives
(codified in dynamic restriction). The resulting story had simple, clean predictions: attitude verbs, when restricted, are always restricted by dynamically
supplied propositions. When an attitude verb appears in the consequent of a
conditional, the underlying set of possibilities is (optionally) restricted by the
content of the conditional’s antecedent; when an attitude verb appears in the
second disjunct of a disjunction, the underlying set of possibilities is (optionally)
restricted by the content of the negation of the first disjunct; etc.; otherwise the
verb always takes its normal reading. We then observed that the presence of
restriction also seemed to depend on the verb’s subject being in the first person
and its tense being present, and so added fp restriction as a further constraint (with reservations). But then evidential factives and ‘want’ entered the
picture, and both dynamic and fp restriction were found to be wanting—at
least on the assumption that the underlying phenomenon is a unified one.
Although we believe the entries for verbs like ‘think’, ‘know’, and ‘regret’
stated in ➜3 are ultimately correct, we are without a general account of the
underlying mechanisms that tells us when a restriction will appear and what its
content will be when it does. We believe the task of finding such an account
will prove to be highly non-trivial. But we also believe it should be a matter of
broad theoretical interest. For not only is the question of the proper semantics
for attitude verbs interesting in its own right, but given the nature of the data
we are dealing with, there are reasons to believe that its investigation may shed
new light on debates about epistemic modals and the nature of knowledge.
