A System of Logic ratiocinative and inductive being a connected view of the principles of evidence and the methods of scientific investigation.

Ninth edition; 2 vols (22.5 x 15 cm); minor spotting, hinges cracked at endpapers; publisher's pebble-grain blue-green cloth, covers ruled in blind, printed labels to spines, a trifle rubbed at extremities, very good; xx, 563, [1]; xv, [1], 557, [1]pp. The first posthumous edition of J.S. Mill's (1806-1873) greatest work of pure philosophy. First published in 1843, A System of Logic was the result of twelve years of labour in which Mill attempted to find a coherent method of scientific inquiry that could explain the operation of 'moral and social phenomena' (Preface) in the real world. As a result, the book courted great controversy from its first publication in 1843, receiving criticism from defenders of more traditional systems of ethics rooted in metaphysics and theology.
