is, as Chrysippus states, in his Dialectics, and Diogenes, too, in his Dialectic Art; that which is held together by the copulative conjunction “if.” And this conjunction professes that the second member of the sentence follows the first, as for instance, “If it is day, it is light.” That which is adjunctive is, as Crinis states in his Dialectic Art, an axiom which is made to depend on the conjunction “since” (ἐπεὶ), beginning with an axiom and ending in an axiom, as for instance, “Since it is day, it is light.” And this conjunction professes both that the second portion of the proposition follows the first, and the first is true. That is a connected proposition which is connected by some copulative conjunctions, as for instance, “It both is day, and it is light.” That is a disjunctive proposition which is disconnected by the disjunctive conjunction, “or” (ἤτοι), as for instance, “It is either day or night.” And this proposition professes that one or other of these propositions is false. That is a causal proposition which is connected by the word, “because;” as for instance, “Because it is day, it is light.” For the first is, as it were, the cause of the second. That is an augmentative proposition, which explains the greater, which is construed with an augmentative particle, and which is placed between the two members of the proposition, as for instance, “It is rather day than night.” The diminutive proposition is, in every respect, the exact contrary of the preceding one; as for instance, “It is less night than day.” Again, at times, axioms or propositions are opposed to one another in respect of their truth and falsehood, when one is an express denial of the other; as for instance, “It is day,” and, “It is not day.”
Again, a conjunctive proposition is correct, when it is such that the opposite of the conclusion is contradictory of the premiss; as for instance, the proposition, “If it is day,
