Cacozelia, or perverse affectation, is a fault in every kind of style: for it includes all that is turgid, trivial, luscious, redundant, far-fetched or extravagant, while the same name is also applied to virtues
This form of affectation, however, affects style alone. For the employment of arguments which might equally well be advanced by the other side, or are foolish, inconsistent or superfluous, are all faults of matter, whereas corruption of style is revealed in the employment of improper or redundant words, in obscurity of meaning, effeminacy of rhythm, or in the childish search for similar or ambiguous expressions.
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.
