judgments, of syllogisms, of imperfect enunciations, of attributes and deficiencies, and of both direct and indirect categorems or predicaments.
XLVII. And they say that enunciation is the manifestation of the ideal perception; and these enunciations the Stoics pronounce some to be perfect in themselves, and some to be defective; now those are defective, which furnish an incomplete sense, as for instance, “He writes.” For then we ask further, “Who writes?” But those are perfect in themselves, which give a sense entirely complete, as for instance, “Socrates writes.” Accordingly, in the defective enunciations, categorems are applied; but in those which are perfect in themselves, axioms, and syllogisms, and questions, and interrogations, are brought into play. Now a categorem is something which is predicated of something else, being either a thing which is added to one or more objects, according to the definition of Apollodorus, or else a defective enunciation added to the nominative case, for the purpose of forming a proposition.
Now of categorems, some are accidents …2 as for instance, “The sailing through a rock.” … And of categorems, some are direct, some indirect, and some neither one nor the other. Now those are correct, which are construed with one of the oblique cases, in such a manner as to produce a categorem, as for instance, “He hears, he sees, he converses.” And those are indirect, which are construed with the passive voice, as for instance, “I am heard, I am seen.” And those which are neither one nor the other, are those which are construed in a neutral kind of manner, as for instance, “To think, to walk.” And those are reciprocal, which are among the indirect ones, without being indirect themselves. Those are effects, ἐνεργήματα, which are such words as, “He is shaved;” for then, the man who is shaved, implies himself.
The oblique cases, are the genitive, the dative, and the accusative.
XLVIII. An axiom, is that thing which is true, or false, or perfect in itself, being asserted,
