The soul is the form of the body, but not as the shape of a statue is formatio et terminatio materiae, for form does not exist apart from material. There is no whiteness without a white object. But the soul is not a form in this simple sense, and in particular, is not the shape of the material it informs. Therefore, the shape of a being does not affect the being's soul, for then something lower would inform something higher, which is impossible.
Michael Flynn, Eifelheim
