Brief summaries of selected sections of Graham Priest’s Introduction to Non-Classical Logic: From If to Is, chosen for their relevance to a study of the logic of Gilles Deleuze

Michael Wolff's new preface to my translation of his Essay on the Principles of Logic: A Defense of Logical Monism.

Analytic philosophy and modern logic are intimately connected, both historically and systematically. Thinkers such as Frege, Russell, and Wittgenstein were major contributors to the early development of both; and the fruitful use of modern logic in addressing philosophical problems was, and still is, definitive for large parts of the analytic tradition. More specifically, Frege's analysis of the concept of number, Russell's theory of descriptions, and Wittgenstein's notion of tautology have long been seen as paradigmatic pieces of philosophy in this tradition. This close connection remained beyond what is now often called "early analytic philosophy", i.e., the tradition's first phase. In the present chapter I will consider three thinkers who played equally important and formative roles in analytic philosophy's second phase, the period from the 1920s to the 1950s: Rudolf Carnap, Kurt Gödel, and Alfred Tarski.

This paper is more a series of notes than a scholarly treatise. It focuses on certain achievements of Aristotle, Boole and Tarski. The notes presented here using concepts introduced or formalized by Tarski contribute toward two main goals: comparing Aristotle’s system with one Boole constructed intending to broaden and to justify Aristotle’s, and giving a modern perspective to both logics. Choice of these three logicians has other advantages. In history of logic, Aristotle is the best representative of the earliest period, Boole the best of the transitional period, and Tarski the best of the most recent period. In philosophy of logic, all three were amazingly successful in having their ideas incorporated into mainstream logical theory. This last fact makes them hard to describe to a modern logician who must be continually reminded that many of the concepts, principles, and methods that are taken to be “natural” or “intuitive” today were all at one time discoveries. Keywords: Counterargument, countermodel, formal epistemology, formal ontology, many‑sorted, metalogic, one‑sorted, proof, range‑indicator, reinterpretation.

La lógica experimenta actualmente un crecimiento vertiginoso. Acompañada de un impulso inter y transdisciplinario, se despliega como un saber que transforma la naturaleza de las nociones de epistemolog&iacure;a y semántica. Es hora de que los filósofos se confronten a los problemas y a las nuevas preguntas esbozadas por estos avances. En verdad es manifiesto que hay ya algunos emprendimientos importantes en ese sentido. Emprendimientos que contribuyen en la exploración de nuevas direcciones del rol de la lógica como organon. El objetivo principal de nuestra colección es precisamente promover la publicación y traducción de obras en lengua castellana sobre lógica, filosofía de la lógica, filosofía de la ciencia, epistemología y semántica de la lenguas naturales. Esperamos que un tal foro de publicación fomentará la consolidación de vínculos ya existentes entre las disciplinas mencionadas y la construcción de nuevos lazos inter-y transdisciplinarios. Logic is nowadays growing at a breathtaking pace with a trans-and interdisciplinary élan which is transforming the very nature of the notion of epistemology and semantics. The time is ripe for philosophers to take up the challenges resulting from this impulse and indeed there are clear signals that many philosophers have already responded by taking upon themselves the task of reinstating logic in a new version of its old role of organon.The aim of this series is to promote the publication in Spanish of worksin logic, philosophy of logic, philosophy of science, epistemology and semantic for natural languag. This publication forum should foster the consolidation of existing links between those disciplines and the building of new inter and transdisplinary ones. The Volume La lógica como herramienta de la razón has been published by the UK publisher College Publications. Their Spanish language series Cuadernos de Logica, Epistemologia y Lenguaje, distinguishes itself by promoting and supporting researche in the field of Logic, where logic takes anew the role of an Organon, prescribed in Antiquity by Aristotle. Nowadays; this role of logic is deployed in its inter-and transdisciplianry character. Two other salient characteristics of this collection that I would like to point out, is as, already mentioned, that it publishes original work in Spanish and the second is copyright policy of all CP titles that allows authors to retain full rights for their own work. Prof. Atocha Aliseda (Universidad Autonoma de Mexico) We congratulate, moreover (the Spanish-speaking scientific community) should congratulate ourselves for the launching of a collection that promotes the publication in Spanish of work in this field, " Prof Arancha San Ginés (Universidad de Granada) Extracted from the Radio interview with Atocha Aliseda (Universidad Autonoma de Mexico), on the occassion of the publication in 2014 of her book La lógica como herramienta de la razón.
