Sir Kenelm Digby (1603–1665) was one of the main figures of the 17th century. Descartes and Hobbes were friends of his, and Digby marked the beginning of the English reception of Descartes. In his work ‹Two Treatises‹, he attempted to settle the differences between the philosophy of Aristotle, the advocates of the mechanistic world view and the continental idealism of his time. In this context, he developed a complex corpuscular theory and analyzed cognitive processes and the concept of substance ultimately in order to establish proof of the immortality of the soul.
