(It might be objected) that if the souls on high do not reason, they will no longer be reasonable. They remain reasonable, however, because they are well able to penetrate into the essence of something, whenever the occasion demands it. Ratiocination should be considered as follows. If it consist in a disposition that is always derived from Intelligence, in an immanent act, a reflection of this power in souls, these must also reason in the intelligible world; but then they have no further need of language. Likewise, when they inhabit heaven, neither do they need to take recourse to speech, as do the souls here below, as a result of their needs and uncertainties. They act in an orderly manner, and in conformity with nature, without premeditation or deliberation. They know each other by a simple intuition, as even here below we know our like without their talking to us, by a mere glance. On high every body is pure and transparent. Each person there, is, as it were, an eye. Nothing is hidden or simulated. Before you have spoken, your thought is already known. It is probable that speech is used by the guardians and other living inhabitants of the air, for they are living beings. D. HOW CAN THE SOUL SIMULTANEOUSLY BE DIVISIBLE AND INDIVISIBLE? A DECISION WILL DEPEND ON THE MEANING OF THE TERMS. 19. Must we consider that (in the soul), the indivisible and the divisible are identical, as if they were mingled together? Or should we consider the distinction between the indivisible and the divisible from some other point of view? Should the first be considered as the higher part of the soul, and the latter as the lower, just exactly as we say that one part of the soul is rational, and the other part is irrational? Such questions can be answered only by a close scrutiny of the nature of the divisibility and indivisibility of the soul. THE BODY NEEDS THE SOUL FOR LIFE. When Plato[130] says that the soul is indivisible, he speaks absolutely. When he insists that she is divisible, it is always relatively (to the body). He does indeed say that she becomes divisible in the bodies, but not that she has become such. Let us now examine how, by her nature, the body needs the soul to live, and what necessity there is for the soul to be present in the entire body. SENSE, GROWTH AND EMOTION TEND TOWARDS DIVISIBILITY.
