The contributors inquire into what activity is taken to mean in different theories, challenging traditional historical accounts of perception that stress the passivity of percipients in coming to know the external world. Special attention is paid to the psychological and physiological mechanisms of perception, rational and non-rational perception and the role of awareness in the perceptual process.
Perception has often been conceived as a process in which the passive aspects - such as the reception of sensory stimuli - were stressed and the active ones overlooked. However, during recent decades research in cognitive science and philosophy of mind has emphasized the activity of the subject in the process of sense perception, often associating this activity to the notions of attention and intentionality. Although it is recognized that there are ancient roots to the view that perception is fundamentally active, the history remains largely unexplored.
The book is directed to all those interested in contemporary debates in the fields of philosophy of mind and cognitive psychology who would like to become acquainted with the historical background of active perception, but for historical reliability the aim is to make no compromises.

The historical span reaches from the late ancient to the early modern philosophy, showing in detail how old and new ideas were bred and brought into the Middle Ages, and how they resulted in a genuinely modern perspective in the thought of Descartes. The essays are original contributions by a mixture of established senior scholars and ...

In this paper, I consider the historically most important theories of how visual perception is made spatial in the cognitive processing of the sensory input
to the eye. In all of them, active engagement of the mind is necessary in order to make visual perception genuinely spatial. The three main models are the following:
1. The brain receives separated three-dimensional visual images, which the mind takes to represent a consistently organized and unified three-dimensional world (Alhacen).
2. T he brain receives a unified two-dimensional visual image, which the mind innately takes to represent a three-dimensional world (Descartes).
3. The brain receives two-dimensional visual images, which the mind associates to the experience of a three-dimensional world given by the proprioceptive senses (Berkeley).

and the medieval genre of sophismata in relation to the kinds of inferences accepted in
them. The main texts discussed are the anonymous Obligationes parisienses from the
early 13th century and Richard Kilvington’s Sophismata from the early 14th century. Four
different kinds of warranted transition from an antecedent to a consequent become
apparent in the medieval discussions: (1) the strong logical validity of basic propositional
logic, (2) analytic validity based on conceptual containment, (3) merely semantic
impossibility of the antecedent being true without the consequent, and (4) intuitively
true counterfactual conditionals. As these different kinds of consequences are spelled
out by means of obligational disputations, it appears that the genre of obligations is
indeed useful for the “knowledge of consequences,” as the anonymous Obligationes
parisienses claims.
