„A proposition, we have before said, is a portion of discourse in which a predicate is affirmed or denied of a subject. A predicate and a subject are all that is necessarily required to make up a proposition: but as we can not conclude from merely seeing two names put together, that they are a predicate and a subject, that is, that one of them is intended to be affirmed or denied of the other, it is necessary that there should be some mode or form of indicating that such is the intention; some sign to distinguish a predication from any other kind of discourse. This is sometimes done by a slight alteration of one of the words, called an inflection“. (Chap. IV, § 1) #Mill #proposition

Mill: Proposition
Zitat
„A proposition being a portion of discourse in which something is affirmed or denied of something, the first division of propositions is into affirmative and negative. An affirmative proposition is that in which the predicate is affirmed of the subject; as, Cæsar is dead. A negative proposition is that in which the predicate is denied of the subject; as, Cæsar is not dead. The copula, in this last species of proposition, consists of the words is not, which are the sign of negation; is being the sign of affirmation.“ (Chap. IV, § 2) #Mill #proposition
Bacon: The Syllogism
Zitat
„The syllogism consists of propositions; propositions of words; words are the signs of notions. If, therefore, the notions (which form the basis of the whole) be confused and carelessly abstracted from things, there is no solidity in the superstructure. Our only hope, then, is in genuine induction.“ (p. 17) #FrancisBacon #syllogism #proposition #word #sign #notion #superstructure
La conversion
Zitat
„La conversion consistant à permuter le sujet et l’attribut d’une proposition, la seule question est de savoir à quelles conditions cette permutation peut se faire salva veritate, c’est-à-dire de telle manière que, la proposition initiale étant supposée vraie, sa converse le soit également.“ (p. 284)
La proposition
Zitat
„La proposition se révèle alors être la formulation linguistique du jugement : sa structure grammaticale reflète les conditions de production du jugement.“ (p. 123)
