 The French Cartesian Nicolas Malebranche was hailed by his contemporary, Pierre Bayle, as “the premier philosopher of our age.” Over the course of his philosophical career, Malebranche published major works on metaphysics, theology, and ethics, as well as studies of optics, the laws of motion and the nature of color. He is known principally for offering a highly original synthesis of the views of his intellectual heroes, St. Augustine and René Descartes. Two distinctive results of this synthesis are Malebranche’s doctrine that we see bodies through ideas in God and his occasionalist conclusion that God is the only real cause.
