Lecture 2.1 Categories
Organization of the Categories
A. Generate the list of beings of the world
1. ask ti esti of the objects there are in the world
2. then ask of those objects poion, poson, pros ti, etc.
result: lists of primary objects
3. now ask ti esti of all these objects
result: secondary substances, qualities, etc.
B. Classify their predication relations
1. the ‘predicated of’ relation is already done
*origin of syllogistic
2. the ‘present in’ relation is implied in A.1 and 2
C. The less subject they are, the less being they have
1. primary substance: not predicated of, not present in
2. secondary substance: predicated of, not present in
3. primary non-substance: not predicated of, present in
4. secondary non-substance: predicated of, present in
predicated of not predicated of
(name and def’n)
present in 2ry non-subst primary non-subst
(name only, pallor this pallor
if that)
not present in 2ry substance primary substance
Man Socrates
Non-composites: substance, quantity, quality, relation, place time, position, state, action, affection (no division: being is not a genus)
predicated of: not explained (but part of definition)
present in: not as part of whole, but incapable of existence apart from the subject
Transitivity
Quality Substance
color animal

pale predicated of present in --> man
|
this pale v this man
Definitions: Genus and Differentia
A. Divisions are through differentiae
1. differentiae are predicated of their subjects
but differentiae are poion
2. specific differentiae are unique
3. differentiae, like genera, are predicated of transitively!
e.g. footed of man
Propria of Substance
A. substance has no contrary
nor does quantity, at least definite quantity (e.g. 3)
B. substance does not admit of variation of degrees
C. while remaining one and the same, it is capable of admitting contrary qualities
this belongs to substance alone
