The famous Port-Royal logic, which revolutionized the treatment of logic. Though realy a "handbook on method rather than a study of formal logic in the strict sense, it was strongly and conscously Cartesian -- roughly, a development from Desc arte's Regulae rather than Aristotle's Prior Analytica. By greatly elaborating the theory of clear and distinct ideas, Anauld sought to provide a way to science that would avoid Pyrrhonism" [Harry M. Bracken's essay on Arnauld i n the the Encyclopedai of Philosophy 1: 465].

"Boole invented the first practical system of logic in algebraic form, which enabled more advances in logic to be made in the decades of the nineteenth century than in the twenty-two centuries preceding. Boole's work led to the creation of se t theory and probability theory in mathematics, to the philosophical work of Peirce, Russell, Whitehead and Wittgenstein and to computer technology via the master's thesis of C.E. Shannon (1937), who recognized that the true/false values in Boole's two-v alued algebra were analogous to the open and closed states of electric circuits. This invention of the binary digit or 'bit' made possible the development of the digital computer" [Norman Catalog].

The famous and oft-reproduced frontis wood engraving to volume one illustrates Jevons's logical piano, the first logic machine actually built."... Jevons's fame as the inventor of a logic machine has tended to obscure the important role he pl ayed in the history of both inductive and deductive logic. He was one of the pioneers of modern symbolic logic, and his Principles of Science, first issued in 1874, deserves far more recognition than it has today as an important treatise on the philosophy and methods of science. At a time when most British logicians ignored or damned with faint praise the remarkable achievements of George Boole, Jevons was quick to see the importance of Boole's work as well as many of its defects" [Martin G ardner, Logic Machines and Diagrams (McGraw-Hill, 1958), p.92].

Keynes' only philosophical book is a classic contribution to the philosophy of probability. Keynes' principal thesis -- that there are inferences in which the premises do not entail the conclusion but which have an objective rather than subje ctive probability -- less good reason for believing it" -- along with the famous Principle of Limited Independent Variety articulated in chapter 20 have had great influence on subsequent theorizing about probablity.

By the end of the 19th century a considerable body of work existed on the algebra of logic -- primary works by Boole, De Morgan, and others; numerous secondary textbooks and manuals; the writings of mathematicians su ch as Dedekind; and the many papers (published and unpublished) on the subject by C. S. Peirce. Schröder's achievement was to assimilate and oranize all these various systems of notation. With the aid of an improved symbolism he was able to present a sys tematic treatment of the formal algebra of logic, which paved the way for the treatment of symbolic logic as an indedendent discipline and provided a transitional stage for the subject into the 20th century. | Order $400.00

One of the most influential twentieth century contributions to logic and mathematics and now a wildly desirable book to possess in the first edition. Though Gödel showed in the early 1930s "that in any axiomatic system strong enough to prove the truths of elementary arithmetic, there will always be true propositions which cannot be proved in the system, he did not establish that these unprovable propositions are interesting ones. PM does offer proofs of all of the arithmetical p ropositions that anyone is ever likely to want to use." [letter from John Slater to me correcting an earlier description]. In the 1950s Gregory Bateson used the theory of types set forth in volume one as the foundation for his double-bind theory of schiz ophrenia, while Ignacio Matte-Blanco in The Unconscious as Infinite Sets showed that primary and secondary process thinking follow, respectively, the Russellian rules for symmetrical and asymmetrical logic.
