Book 7
1.67
An imperative is something which conveys a command: e.g. Go thou to the waters of Inachus.Nauck, T.G.F.2, Adesp. 177; cf. Galen, xiii. p. 363 K. An adjurative utterance is something ... A vocative utterance is something the use of which implies that you are addressing some one; for instance: Most glorious son of Atreus, Agamemnon, lord of men.Iliad ix. 96. A quasi-proposition is that which, having the enunciation of a judgement, yet in consequence of the intensified tone or emotion of one of its parts falls outside the class of judgements proper, e.g. Yea, fair indeed the Parthenon! How like to Priam’s sons the cowherd is!Nauck, T.G.F.2, Adesp. 286.
1.68
There is also, differing from a proposition or judgement, what may be called a timid suggestion, the expression of which leaves one at a loss, e.g. Can it be that pain and life are in some sort akin? Interrogations, inquiries and the like are neither true nor false, whereas judgements (or propositions) are always either true or false.
1.68
The followers of Chrysippus, Archedemus, Athenodorus, Antipater and Crinis divide propositions into simple and not simple. Simple are those that consist of one or more propositions which are not ambiguous, as It is day. Not simple are those that consist of one or more ambiguous propositions.
1.69
They may, that is, consist either of a single ambiguous proposition, e.g. If it is day, it is day, or of more than one proposition, e.g. If it is day, it is light.
