Published in 1946, this volume does not purpose to be a treatise on logic. The author's contributions to the substance of logical doctrine have been made in his other works. What he has attempted in the studies that form this volume is an exploration of the periphery of logic, the relation of logic to the rest of the universe, the philosophical presuppositions which give logic its meaning and the applications which give it importance. It is his belief that formal logic (...) is the heart of philosophy, since the subject matter of logic is the formal aspect of all being. From this standpoint he explores the relation of logic to such fields of study as natural science, ethics, history and general philosophy. (shrink)

First published in 1931, this volume represents the culmination of twenty years' of the study on the principles of science. Noticing a widespread craving for philosophical light at a time of scant such offerings, Morris R. Cohen aimed to demonstrate here the fundamental and ancient connection between nature and science - between hearts and minds - in an attempt to salve the developing mutual hostility between the two in the 1920s. The volume bears particular relation to George Santayana's (...) Life of Reason and Bertrand Russell's Principles of Mathematics and explores areas including the character of the insurgence against reason and reason in the contexts of the natural and social sciences.
