  The fortune of the metaphysical and epistemological aspects of Descartes' philosophy is complex. In his own time,  he inspired a raft of followers, who sought to develop his metaphysics, epistemology, natural philosophy, and even to add a worked-out ethics. These authors included Geraud de Cordemoy, Arnold Geulincx, Antoine Le Grand, Nicolas Malebranche, Regis, and Rohault. The British philosopher Henry More at first followed Descartes but subsequently turned against him. Other major philosophers, including Benedict de Spinoza and G. W. Leibniz, were influenced by Descartes' thought  but developed their own, distinct systems.
