THE RELATION OF MATTER TO REASON ILLUSTRATED BY THAT OF OPINION AND IMAGINATION.
15. The objects that concentrate the rays of the sun, are themselves visible, by receiving from the fire of sensation what takes fire in their hearth. They appear because the images that form themselves are around and near them, and touch each other, and finally because there are two limits in these objects. But when the ("seminal) reason" is in matter, it remains exterior to matter in an entirely different manner; it has a different nature. Here it is not necessary that there be two limits; matter and reason are strangers to each other by difference of nature, and by the difference between their natures that makes any mixture of them impossible. The cause that each remains in itself is that what enters into matter does not possess it, any more than matter possesses what enters into it. That is how opinion and imagination do not mingle in our soul,[75] and each remains what it was, without entailing or leaving anything, because no mingling can occur. These powers are foreign to each other, not in that there is a mere juxtaposition, but because between them obtains a difference that is grasped by reason, instead of being seen by sight. Here imagination is a kind of phantom, though the soul herself be no phantom, and though she seem to accomplish, and though she really accomplish many deeds as she desires to accomplish them.
Thus imagination stands to the soul in about the same lation as (form) with matter. Nevertheless (imagination) does not hide the soul, whose operations often disarrange and disturb it. Never could imagination hide the soul entirely, even if imagination should penetrate the soul entirely, and should seem to veil it completely. Indeed, the soul contains operations and reasons contrary (to imagination), by which she succeeds in putting aside the phantoms that besiege her.[76] But matter, being infinitely feebler than the soul, possesses none of the beings, either of the true or false, which characteristically belong to it. Matter has nothing that could show it off, being absolutely denuded of all things. It is no more than a cause of appearance for other things; it could never say, "I am here, or there!" If, starting from other beings,[77] profound reasoning should succeed in discovering matter, it ultimately declares that matter is something completely abandoned by true beings; but as the things that are posterior to true beings themselves seem to exist, matter might, so to speak, be said to be extended in all these things, seeming both to follow them, and not to follow them.
