| Paragraph 1 |
If a syllogistic question is equivalent to a proposition embodying one of the two sides of a contradiction, and if each science has its peculiar propositions from which its peculiar conclusion is developed, then there is such a thing as a distinctively scientific question, and it is the interrogative form of the premisses from which the 'appropriate' conclusion of each science is developed. |
| Paragraph 2 |
Since there are 'geometrical' questions, does it follow that there are also distinctively 'ungeometrical' questions? |
| Paragraph 3 |
If a proof has an inductive minor premiss, one should not bring an 'objection' against it. |
| Paragraph 4 |
Reciprocation of premisses and conclusion is more frequent in mathematics, because mathematics takes definitions, but never an accident, for its premisses-a second characteristic distinguishing mathematical reasoning from dialectical disputations. |
| Paragraph 5 |
A science expands not by the interposition of fresh middle terms, but by the apposition of fresh extreme terms. |
