An Introduction to Non-Classical Logic


Graham Priest - 2001
    Part 1, on propositional logic, is the old Introduction, but contains much new material. Part 2 is entirely new, and covers quantification and identity for all the logics in Part 1. The material is unified by the underlying theme of world semantics. All of the topics are explained clearly using devices such as tableau proofs, and their relation to current philosophical issues and debates are discussed. Students with a basic understanding of classical logic will find this book an invaluable introduction to an area that has become of central importance in both logic and philosophy. It will also interest people working in mathematics and computer science who wish to know about the area.

Lectures on the Foundations of Mathematics, Cambridge 1939


Ludwig Wittgenstein - 1989
    A lecture class taught by Wittgenstein, however, hardly resembled a lecture. He sat on a chair in the middle of the room, with some of the class sitting in chairs, some on the floor. He never used notes. He paused frequently, sometimes for several minutes, while he puzzled out a problem. He often asked his listeners questions and reacted to their replies. Many meetings were largely conversation. These lectures were attended by, among others, D. A. T. Gasking, J. N. Findlay, Stephen Toulmin, Alan Turing, G. H. von Wright, R. G. Bosanquet, Norman Malcolm, Rush Rhees, and Yorick Smythies. Notes taken by these last four are the basis for the thirty-one lectures in this book. The lectures covered such topics as the nature of mathematics, the distinctions between mathematical and everyday languages, the truth of mathematical propositions, consistency and contradiction in formal systems, the logicism of Frege and Russell, Platonism, identity, negation, and necessary truth. The mathematical examples used are nearly always elementary.

التفكير المستقيم والتفكير الأعوج


Robert H. Thouless - 1930
    An introduction to logical thinking and the tricks of argument, with 37 demonstrations of illogical and crooked thinking, and how they may be overcome by the use of straight thought.

Introduction to Mathematical Philosophy


Bertrand Russell - 1918
    In it, Russell offers a nontechnical, undogmatic account of his philosophical criticism as it relates to arithmetic and logic. Rather than an exhaustive treatment, however, the influential philosopher and mathematician focuses on certain issues of mathematical logic that, to his mind, invalidated much traditional and contemporary philosophy.In dealing with such topics as number, order, relations, limits and continuity, propositional functions, descriptions, and classes, Russell writes in a clear, accessible manner, requiring neither a knowledge of mathematics nor an aptitude for mathematical symbolism. The result is a thought-provoking excursion into the fascinating realm where mathematics and philosophy meet — a philosophical classic that will be welcomed by any thinking person interested in this crucial area of modern thought.

The Foundations of Arithmetic: A Logico-Mathematical Enquiry into the Concept of Number


Gottlob Frege - 1884
    The book represents the first philosophically sound discussion of the concept of number in Western civilization. It profoundly influenced developments in the philosophy of mathematics and in general ontology.

An Investigation of the Laws of Thought


George Boole - 1854
    A timeless introduction to the field and a landmark in symbolic logic, showing that classical logic can be treated algebraically.

Logical Investigations, Volume 1


Edmund Husserl - 1900
    It had a decisive impact on twentieth century philosophy and is one of few works to have influenced both continental and analytic philosophy.This is the first time both volumes have been available in paperback. They include a new introduction by Dermot Moran, placing the Investigations in historical context and bringing out their contemporary philosophical importance.These editions include a new preface by Sir Michael Dummett.

Philosophical Devices: Proofs, Probabilities, Possibilities, and Sets


David Papineau - 2012
    Notions like denumerability, modal scope distinction, Bayesian conditionalization, and logical completeness are usually only elucidated deep within difficultspecialist texts. By offering simple explanations that by-pass much irrelevant and boring detail, Philosophical Devices is able to cover a wealth of material that is normally only available to specialists.The book contains four sections, each of three chapters. The first section is about sets and numbers, starting with the membership relation and ending with the generalized continuum hypothesis. The second is about analyticity, a prioricity, and necessity. The third is about probability, outliningthe difference between objective and subjective probability and exploring aspects of conditionalization and correlation. The fourth deals with metalogic, focusing on the contrast between syntax and semantics, and finishing with a sketch of Godel's theorem.Philosophical Devices will be useful for university students who have got past the foothills of philosophy and are starting to read more widely, but it does not assume any prior expertise. All the issues discussed are intrinsically interesting, and often downright fascinating. It can be read withpleasure and profit by anybody who is curious about the technical infrastructure of contemporary philosophy.

Property Of, The Drowning Season, Fortune's Daughter, and At Risk: Four Novels in One Collection


Alice Hoffman - 2016
    One of today’s most beloved authors of lyrical fiction with a touch of magic, Alice Hoffman boasts a body of work that has been praised by readers and critics from the very beginning. This collection includes her first novel, plus three more of her outstanding tales.  Property Of: Hoffman’s debut about teenage girls in mascara and leather and their attraction to local toughs is “a remarkably envisioned novel, almost mythic in its cadences” (The New York Times).  The Drowning Season intertwines the stories of two women named Esther: a granddaughter, who yearns to escape the Long Island shore and the coldness of the family matriarch; and her grandmother, who fled her abusive parents in Russia decades before. This novel “casts the spell of all great fairy tales. It takes daily life and transforms it into myth as we watch” (Chicago Sun-Times).  Fortune’s Daughter: A New York Times Notable Book, this luminous novel of a restless young traveler and a fortune-teller with a secret is a tribute to the profound mysteries of motherhood and childbirth from a writer who, in the words of Amy Tan, “takes seemingly ordinary lives and lets us see and feel extraordinary things.”  At Risk is a New York Times bestseller that “will leave few dry eyes” (Library Journal). In 1980s America, a family copes with their daughter’s terrifying AIDS diagnosis.
