Let us now grant that symmetrical analysis by individual objects is impossible. Might we not, as a means of classification, then employ analogy? In this case the (intelligible, higher) "being" would here be represented by matter; and movement above, by form here, which would thus quicken and perfect matter. The inertia of matter would correspond to rest above, while the (intelligible) identity and difference would correspond to our earthly manifold resemblance and differences.[351] (Such an analogic method would misrepresent the state of affairs in this world). To begin with, matter does not receive form as its life or actualization, but (form) approaches and informs (matter) as something foreign (form deriving from being, while matter is only a deception; so that there is no kinship between them). Then in the (intelligible world) form is an actualization and motion, while here below movement is different, being accidental; we might far rather call form the halting or rest of matter, for form defines that which in itself is indefinite (unlimited). There (in the intelligible world) identity and difference refer to a single essence, which is both identical and different. Here below, essence differs only relatively, by participation (in the difference) for it is something identical and different, not by consequence, as above, but here below, by nature. As to stability, how could it be attributed to matter, which assumes all dimensions, which receives all its forms from without, without itself ever being able to beget anything by means of these forms? Such a division, therefore, will have to be given up. PHYSICAL CATEGORIES ARE MATTER, FORM, COMBINATION, ATTRIBUTES AND ACCIDENTS. 3. What classification shall we adopt? There is first matter, then form, and further the combination which results from their blending. Then we have a number of conceptions which refer to the three preceding classes, and are predicated of them; the first, simply, as attributes; the others, besides, as accidents. Among the latter, some are contained within the things, while others contain them; some of them are actions, and the others experiences (passions) or their consequences. THE THREE FIRST PHYSICAL CATEGORIES OF MATTER, FORM AND COMBINATION.
