THE BODY EXERTS A UNIFORM ACTION, WHILE THE SOUL EXERTS A VARIED ONE.
(g.) (The body exerts an uniform action, while the soul exerts a very diverse action.) The following considerations further demonstrate the impossibility of the soul being a body. A body must be hot or cold, hard or soft, liquid or solid, black or white, or qualities differing according to its nature. If it is only hot or cold, light or heavy, black or white, it communicates its only quality to what comes close to it; for fire could not cool, nor ice heat. Nevertheless, the soul produces not only different effects in different animals, but contrary effects even in the same being; she makes certain things solid, dense, black, light, and certain others liquid, sparse, white, or heavy. According to the different quality of the body, and according to its color, she should produce but a single effect; nevertheless, she exerts a very diverse action.
