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. |
