This volume presents the philosophical and heuristic framework Cantor developed and explores its lasting effect on modern mathematics. "Establishes a new plateau for historical comprehension of Cantor's monumental contribution to mathematics." --The American Mathematical Monthly.

This paper treats some of the issues raised by Putnam's discussion of, and claims for, quantum logic, specifically: that its proposal is a response to experimental difficulties; that it is a reasonable replacement for classical logic because its connectives retain their classical meanings, and because it can be derived as a logic of tests. We argue that the first claim is wrong (1), and that while conjunction and disjunction can be considered to retain their classical meanings, negation crucially does not. (...) The argument is conducted via a thorough analysis of how the meet, join and complementation operations are defined in the relevant logical structures, respectively Boolean- and ortholattices (3). Since Putnam wishes to reinstate a realist interpretation of quantum mechanics, we ask how quantum logic can be a logic of realism. We show that it certainly cannot be a logic of bivalence realism (i.e., of truth and falsity), although it is consistent with some form of ontological realism (4). Finally, we show that while a reasonable explication of the idealized notion of test yields interesting mathematical structure, it by no means yields the rich ortholattice structure which Putnam (following Finkelstein) seeks.

The volume includes twenty-five research papers presented as gifts to John L. Bell to celebrate his 60th birthday by colleagues, former students, friends and admirers. Like Bell’s own work, the contributions cross boundaries into several inter-related fields. The contributions are new work by highly respected figures, several of whom are among the key figures in their fields. Some examples: in foundations of maths and logic ; analytical philosophy, philosophy of science, philosophy of mathematics and decision theory and foundations of economics. (...) Most articles are contributions to current philosophical debates, but contributions also include some new mathematical results, important historical surveys, and a translation by Wilfrid Hodges of a key work of arabic logic.

Hungarian-born Stefan Lorant's work as a visual and literary editor allowed him to pioneer and develop the genré of picture-based journalism at a period that saw the emergence of modern mass communications. Lorant became a guiding force on an international scale, disseminating his ideas and political knowledge throughout Europe in the late-twenties and thirties by working in Hungary, Germany, and England. His innovative layouts, his "exclusive" interviews and his thirst for knowledge became a familiar part of millions of everyday lives, (...) largely through the pages of his own creations and in particular the legendary Picture Post. Eventually his sphere of influence spread to America where he introduced the concept of the pictorial biography. His vision of photography as a documentary medium inspired Life and Look magazines and paved the way for the eventual emergence of the television documentary. For this he has become recognized as "the godfather" of photojournalism. Lorant's work enlightened the world - yet his own world was shrouded with darkness. His secret past, hidden throughout his lifetime, reveals the changing attitude of sexual politics as it evolved throughout the century. His serial womanizing and scandalous love affairs provide insight into the unhappy alliance between his sexual fulfillment and intellectual frustration, his searching in others for what he could not find within himself. Michael Hallett first interviewed Stefan Lorant in late 1990 and spent the following years researching and interviewing his subject. Hallett examines Lorant's public image, his huge ego, his manipulative nature, and his devious love of subterfuge and confusion. Hallett also reveals Lorant's warmth, his generosity, his callousness, his passions and his extraordinary humanity. This biography encompasses the 20th century, while focusing on the emergence of modern mass communications throughout Europe and the United States. Additionally there is a small but key section that highlights Lorant's pl. (shrink)

Exploring the Illusion of Free Will and Moral Responsibility is an edited collection of new essays by an internationally recognized line-up of contributors. It is aimed at readers who wish to explore the philosophical and scientific arguments for free will skepticism and their implications.

The usual objections to infinite numbers, and classes, and series, and the notion that the infinite as such is self-contradictory, may... be dismissed as groundless. There remains, however, a very grave difficulty, connected with the contradiction [of the class of all classes not members of themselves]. This difficulty does not concern the infinite as such, but only certain very large infinite classes.

Charting a "middle way" between the extremes represented by Alvin Plantinga and Richard Swinburne, Garth Hallett explores the thesis that if belief in other minds is rational and true, so too is belief in God. He makes a strong case that when this parity claim is appropriately restricted to a single, sound other-minds belief, belief in God and belief in other minds do prove epistemically comparable. This result, and the distinctive path that leads to it, will interest students and (...) scholars in philosophy of religion and theology. (shrink)

This book defends a form of ethical intuitionism, according to which (i) there are objective moral truths; (ii) we know some of these truths through a kind of immediate, intellectual awareness, or "intuition"; and (iii) our knowledge of moral truths gives us reasons for action independent of our desires. The author rebuts all the major objections to this theory and shows that the alternative theories about the nature of ethics all face grave difficulties.
