7. If there are any now who think that the mind itself and the soul is a body, I wish they would tell me by way of answer how it receives reasons and assertions on subjects of such importance—of such difficulty and such subtlety? Whence does it derive the power of memory? and whence comes the contemplation of invisible things? How does the body possess the faculty of understanding incorporeal existences? How does a bodily nature investigate the processes of the various arts, and contemplate the reasons of things? How, also, is it able to perceive and understand divine truths, which are manifestly incorporeal? Unless, indeed, some should happen to be of opinion, that as the very bodily shape and form of the ears or eyes contributes something to hearing and to sight, and as the individual members, formed by God, have some adaptation, even from the very quality of their form, to the end for which they were naturally appointed; so also he may think that the shape of the soul or mind is to be understood as if created purposely and designedly for perceiving and understanding individual things, and for being set in motion by vital movements. I do not perceive, however, who shall be able to describe or state what is the colour of the mind, in respect of its being mind, and acting as an intelligent existence. Moreover, in confirmation and explanation of what we have already advanced regarding the mind or soul—to the effect that it is better than the whole bodily nature—the following remarks may be added. There underlies every bodily sense a certain peculiar sensible substance, on which the bodily sense exerts itself. For example, colours, form, size, underlie vision; voices and sound, the sense of hearing; odours, good or bad, that of smell; savours, that of taste; heat or cold, hardness or softness, roughness or smoothness, that of touch. Now, of those senses enumerated above, it is manifest to all that the sense of mind is much the best. How, then, should it not appear absurd, that under those senses which are inferior, substances should have been placed on which to exert their powers, but that under this power, which is far better than any other, i.e. the sense of mind, nothing at all of the nature of a substance should be placed, but that a power of an intellectual nature should be an accident, or consequent upon bodies? Those who assert this, doubtless do so to the disparagement of that better substance which is within them; nay, by so doing, they even do wrong to God Himself, when they imagine He may be understood by means of a bodily nature, so that according to their view He is a body, and that which may be understood or perceived by means of a body; and they are unwilling to have it understood that the mind bears a certain relationship to God, of whom the mind itself is an intellectual image, and that by means of this it may come to some knowledge of the nature of divinity, especially if it be purified and separated from bodily matter.
