Abstract
Walton offers a sustained and thorough study of Malebranche’s science of ethics. Much has been written about his Search for Truth but little has been said about his Treatise on Ethics which presents another perspective to Malebranche as a philosopher and extricates him from that sphere of philosophical thinking impoverished by sterility and abstraction, a criticism often unjustly leveled at the so-called Rationalists. Walton starts out by presenting an analysis of Malebranche’s theocentric ontology, an understanding of which is essential to his moral thinking. Malebranche attempts in his Treatise to discover a common denominator in man which can serve as the foundation for a science of ethics. He finds reason to be the controlling factor which not only unites men to each other but unites man to God who Himself is Reason and Wisdom.
