Marleen Rozemond explicates Descartes's aim to provide a metaphysics that would accommodate mechanistic science and supplant scholasticism. Her approach includes a discussion of central differences from and similarities with the scholastics and how these discriminations affected Descartes's defense of the incorporeity of the mind and the mechanistic conception of body. Confronting the question of how, in his view, mind and body are united, she examines his defense of this union on the basis of sensation. In the course of her argument, she focuses on a few of the scholastics to whom Descartes referred in his own writings: Thomas Aquinas, Francisco Suarez, Eustachius of St. Paul, and the Jesuits of Coimbra.
