Nicolas Malebranche is now recognised as a major figure in the history of philosophy, occupying a crucial place in the Rationalist tradition of Descartes, Spinoza and Leibniz. The Search after Truth is his first, longest and most important work; this volume also presents the Elucidations which accompanied its third edition, the result of comments that Malebranche solicited on the original work and an important repository of his theories of ideas and causation. Together, the two texts constitute the complete expression of his mature thought, and are written in his subtle, argumentative and thoroughly readable style. They are presented in the distinguished translations by Thomas M. Lennon and Paul J. Olscamp, together with a historical introduction, a chronology of Malebranche's life, and useful notes on further reading.

Malebranche's Dialogues on Metaphysics and on Religion is in many ways the best introduction to his thought, and provides the most systematic exposition of his philosophy as a whole. In it, he presents clear and comprehensive statements of his two best-known contributions to metaphysics and epistemology, namely, the doctrines of occasionalism and vision in God; he also states his views on such central issues as self-knowledge, the existence of the external world and the problem of theodicy. His skilful handling of the dialogue form enables the reader to see how he responds to objections made to his earlier work The Search after Truth. This edition presents a translation of the text which is clear, readable and more accurate than any of its predecessors, together with an introduction that analyses Malebranche's central teachings and explains the importance of the Dialogues in the context of seventeenth-century philosophy.
