Pure Logic or the Logic of Quality apart from Quantity: with remarks on Boole's System and on the Relation of Logic and Mathematics.

Beschreibung

First edition of the great logician's first book on formal logic, a key refinement of Boolean calculus. Although Jevons is perhaps best known as an economist, his work on logic formed a key part of the wider 19th-century movement to link the discipline with mathematics. Pure Logic reduces the operations of Boolean calculus to a mechanical procedure. In this, Jevons anticipated many of the modern applications of logic in computer programming. He himself designed a "logical abacus" and a "logical piano" to perform the revised calculus, both of which bore strong affinities to his famed truth tables. Inoue & White 58; Risse II, p. 77.
