He taught at the University of Louvain from 1646 but was dismissed in 1658, probably because of his sympathy with Jansenism . He took refuge at Leiden, where he became a Calvinist. He lived in poverty until 1662, when he obtained a position at the University of Leiden. He was a major exponent of the doctrine known as occasionalism . His major works include On Virtue (1665), Know Thyself (1675), and True Metaphysics (1691).
