The French philosopher and theologian Nicholas Malebranche was one of the most important thinkers of the early modern period. A bold and unorthodox thinker, he tried to synthesize the new philosophy of Descartes with the religious Platonism of St. Augustine. This is the first collection of essays to address Malebranche's thought comprehensively and systematically. There are chapters devoted to Malebranche's metaphysics, his doctrine of the soul, his epistemology, the celebrated debate with Arnauld, his philosophical method, his occasionalism and theory of causality, his philosophical theology, his account of freedom, his moral philosophy, and his intellectual legacy.
