Book 7
1.62
Partition in logic is (according to Crinis) classification or distribution of a genus under heads: for instance, Of goods some are mental, others bodily.
1.62
Verbal ambiguity arises when a word properly, rightfully, and in accordance with fixed usage denotes two or more different things, so that at one and the same time we may take it in several distinct senses: e.g. in Greek, where by the same verbal expression may be meant in the one case that A house has three times fallen, in the other that a dancing-girl has fallen.
1.62
Posidonius defines Dialectic as the science dealing with truth, falsehood, and that which is neither true nor false; whereas Chrysippus takes its subject to be signs and things signified. Such then is the gist of what the Stoics say in their theory of language.
1.63
To the department dealing with things as such and things signified is assigned the doctrine of expressions, including those which are complete in themselves, as well as judgements and syllogisms and that of defective expressions comprising predicates both direct and reversed.Direct Predicate answers to our Active Verb, Predicate reversed to our Passive; cf. supra, 43.
1.63
By verbal expression they mean that of which the content corresponds to some rational presentation. Of such expressions the Stoics say that some are complete in themselves and others defective. Those are defective the enunciation of which is unfinished, as e.g. writes, for we inquire Who? Whereas in those that are complete in themselves the enunciation is finished, as Socrates writes. And so under the head of defective expressions are ranged all predicates, while under those complete in themselves fall judgements, syllogisms, questions, and inquiries.
