| Paragraph 1 |
It is an evident corollary of these conclusions that if the same
attribute A inheres in two terms C and D predicable either
not at all,
or not of all instances, of one another, it does not always belong
to them in virtue of a common middle term. |
| Paragraph 2 |
It is also clear that when A inheres in B, this can be
demonstrated if there is a middle term. |
| Paragraph 3 |
When we are to prove a conclusion, we must take a primary
essential predicate - suppose it C-of the subject B, and then suppose
A similarly predicable of C. |
| Paragraph 4 |
(2) If we have to show that E is not D by means of the premisses,
all D is C; |
| Paragraph 5 |
(3) In the third figure the middle will never fall beyond
the limits
of the subject and the attribute denied of it. |
