 Nonetheless, he rejects many principles that are crucial for Aristotle’s account of the soul-body relationship. He argues that it is “not only contrary to reason but also dangerous to the faith” to hold that “the [soul’s] intellective and free part is the form of the body per se and considered as such” (Summa II q. 51, p. 104). Others had questioned the extent to which soul and body could be analyzed in terms of form and matter, but Olivi goes further because he explicitly denies that one part of the soul, the rational part, can be understood as the form of the body. This denial is ultimately based on his view that the intellectual part of the soul must be spiritual and incorporeal because otherwise it cannot be immortal, intellectual, and free. Yet he does not want to jeopardize the substantial unity of the soul and the body, and he works towards a theory which incorporates both of these doctrines.
