In an admirably succinct form, this volume offers a historical view of the development of the calculus of logic, illustrating its beauty, symmetry, and simplicity from an algebraic perspective. Topics include the principles of identity and the syllogism, the principles of simplification and composition; the laws of tautology and of absorption; the distributive law and the laws of duality, double negation, and contraposition; the formulas of De Morgan and Poretsky; Schröder's theorem; sums and products of functions; solution of equations involving one and several unknown quantities; the problem of Boole; Venn diagrams; tables of consequences and causes; and formulas peculiar to the calculus of propositions. 1914 ed. --This text refers to an out of print or unavailable edition of this title.
