A complete survey of mechanical and electrical machines designed to solve problems in formal logic, and of geometrical methods to do the same tasks, must begin with the fascinating eccentricities of the Spanish mystic, Ramon Lull. The Stanhope Demonstrator, Jevons’s Logic Machine, the Marquand Machine and many contemporary devices are fully described and well illustrated. Professor Gardner concludes with a consideration of applications to information storing and processing, and efficient circuit designing.A logic machine is a device, electrical or mechanical, designed specifically for solving problems in formal logic. A logic diagram is a geometrical method for doing the same. The two fields are closely intertwined, and this book is the first attempt in any language to trace their curious, fascinating histories.
