| Paragraph 1 |
In what figure it is possible to draw a conclusion from premisses
which are opposed, and in what figure this is not possible, will be
made clear in this way. |
| Paragraph 2 |
In the first figure no syllogism whether affirmative or
negative can
be made out of opposed premisses: |
| Paragraph 3 |
In the middle figure a syllogism can be made both
oLcontradictories and of contraries. |
| Paragraph 4 |
In the third figure an affirmative syllogism can never be made out
of opposite premisses, for the reason given in reference to the
first figure; |
| Paragraph 5 |
We must recognize that it is possible to take opposites in the way
we said, viz. 'all science is good' and 'no science is good' or
'some science is not good'. |
| Paragraph 6 |
It is clear too that from false premisses it is possible to draw a
true conclusion, as has been said before, but it is not possible if
the premisses are opposed. |
