The Idea of Principle in Leibnitz and the Evolution of Deductive Theory

This book, an exploration of the work of Leibnitz, is Ortega’s most systematic contribution to philosophy. Ortega begins with a detailed definition of a principle and with an examination of the specific principles formulated by Leibnitz. He goes on to examine Leibnitz. He goes on to examine Leibnitz’s complex and mercurial attitudes towards principles and discusses the effects of these attitudes on his philosophy and on contributions to mathematics and logic.
