and their acts an illusion. Thomas Aquinas was instrumental in developing a new doctrine that included the belief in the real power of witches. This was a departure from the teachings of his master Albertus Magnus whose doctrine was based in the Episcopi. The famous 15th-century witch-hunter's manual, the Malleus Maleficarum, also written by a member of the Dominican Order, begins by quoting Thomas Aquinas ("Commentary on Pronouncements" Sent.4.34.I.Co.) refuting the Episcopi and goes on to cite Thomas Aquinas over a hundred times. Promoters of the witch hunts that followed often quoted Thomas more than any other source. Thoughts on afterlife and resurrection A grasp of Thomas's psychology is essential for understanding his beliefs around the afterlife and resurrection. Thomas, following church doctrine, accepts that the soul continues to exist after the death of the body. Because he accepts that the soul is the form of the body, then he also must believe that the human being, like all material things, is form-matter composite. Substantial form (the human soul) configures prime matter (the physical body) and is the form by which a material composite belongs to that species it does; in the case of human beings, that species is rational animal. So, a human being is a matter-form composite that is organized to be a rational animal. Matter cannot exist without being configured by form, but form can exist without matter—which allows for the separation of soul from body. Thomas says that the soul shares in the material and spiritual worlds, and so has some features of matter and other, immaterial, features (such as access to universals). The human soul is different from other material and spiritual things; it is created by God, but also comes into existence only in the material body. Human beings are material, but the human person can survive the death of the body through continued existence of the soul, which persists. The human soul straddles the spiritual and material worlds, and is both a configured subsistent form as well as a configurer of matter into that of a living, bodily human. Because it is spiritual, the human soul does not depend on matter and may exist separately. Because the human being is a soul-matter composite, the body has a part in what it is to be human. Perfected human nature consists in the human dual nature, embodied and intellecting. Resurrection appears to require dualism, which
