Ch.
17. Substance is the cause or form which puts matter into a determinate state; it is that in a thing which is distinct from its material elements.
Η.
1. The discussion of sensible substances continued. Their matter is itself substance.
2. The main types of form or actuality. Definitions of matter, of form, and of the concrete individual distinguished.
3. Form distinguished from the material elements; Antisthenes' attack on definition; definition analogous to number.
4. Remote and proximate matter; the substratum of attributes not matter but the concrete individual.
5. The relation of matter to its contrary states.
6. What gives unity to a definition? The fact that the genus is simply the potency of the differentia, the differentia the actuality of the genus.
Θ.
1. Being as potency and actuality. Potency in the strict sense, as potency of motion, active or passive.
2. Non-rational potencies are single, rational potencies twofold.
3. Potency defended against the attack of the Megaric school.
4. Potency as possibility.
5. How potency is acquired, and the conditions of its actualization.
6. Actuality distinguished from potency; a special type of potency described; actuality distinguished from movement.
7. When one thing may be called the potency or matter of another; how things are described by names derived from their matter or their accidents.
8. Actuality prior to potency in definition, time, and substantiality; nothing eternal or necessary is a mere potency.
9. Good actuality better than potency, and bad actuality worse; therefore no separate evil principle in the universe. Geometrical truths found by actualization of potencies.
10. Being as truth, with regard to both simple and composite objects.
Ι.
1. Four kinds of unit; the essence of a unit is to be a measure of quantity or of quality; various types of measure.
2. Unity not a substance but a universal predicate; its denotation the same as that of being.
3. Unity and plurality; identity; likeness; otherness; difference.
4. Contrariety is complete difference; how related to privation and contradiction.
5. The opposition of the equal to the great and the small.
6. The opposition of the one to the many.
