Division of a genus means dissection of it into its proximate species, thus: Animals are either rational or irrational (dichotomy). Contrary division dissects the genus into species by contrary qualities: for example, by means of negation, as when all things that are are divided into good and not good. Subdivision is division applied to a previous division: for instance, after saying, Of things that are some are good, some are not good, we proceed, and of the not good some are bad, some are neither good nor bad (morally indifferent).

Partition in logic is (according to Crinis) classification or distribution of a genus under heads: for instance, Of goods some are mental, others bodily.

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.

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.
