Aristotle - The Organon - index for TOPICA Book 7 Part 1

Inflections, accidents, categories, degrees...

Paragraph 1 Whether two things are 'the same' or 'different', in the most literal of the meanings ascribed to 'sameness' (and we said that 'the same' applies in the most literal sense to what is numerically one), may be examined in the light of their inflexions and coordinates and opposites.
Paragraph 2 Again, look and see if, supposing the one to be the same as something, the other also is the same as it:
Paragraph 3 Moreover, examine them in the light of their accidents or of the things of which they are accidents:
Paragraph 4 See further whether, instead of both being found in one class of predicates, the one signifies a quality and the other a quantity or relation.
Paragraph 5 Moreover, from the point of view of 'degrees', see if the one admits an increase of degree but not the other, or if though both admit it, they do not admit it at the same time;
Paragraph 6 Moreover, examine them by means of an addition, and see whether the addition of each to the same thing fails to make the same whole;
Paragraph 7 Inquire also not only if some impossible consequence results directly from the statement made, that A and B are the same, but also whether it is possible for a supposition to bring it about;
Paragraph 8 Speaking generally, one ought to be on the look-out for any discrepancy anywhere in any sort of predicate of each term, and in the things of which they are predicated.
Paragraph 9 Moreover, as 'sameness' is a term used in many senses, see whether things that are the same in one way are the same also in a different way.
Paragraph 10 Moreover, see whether the one can exist without the other;
