Further, it always involves insincerity, even though all insincerity does not imply affectation. For it consists in saying something in an unnatural or unbecoming or superfluous manner. Style may, however, be corrupted in precisely the same number of ways that it may be adorned. But I have discussed this subject at greater length in another work, The lost De causis corruptae eloquentiae. and have frequently called attention to it in this, while I shall have occasion to mention it continually in the remaining books. For in dealing with ornament, I shall occasionally speak of faults which have to be avoided, but which are hard to distinguish from virtues.

To these blemishes may be added faulty arrangement or ἀνοικονόμητον, the faulty use of figures or ἀσχημάτιστον, and the faulty collocation of words or κακοσύνθετον. But, as I have already discussed arrangement, I will confine myself to the consideration of figures and structure. There is also a fault known as Σαρδισμὸς, which consists in the indiscriminate use of several different dialects, as, for instance, would result from mixing Doric, Ionic, and even Aeolic words with Attic.
