Aristotle, Rhetoric
J. H. Freese, Ed.

[3] Now the proofs furnished by the speech are of three kinds. The first depends upon the moral character of the speaker, the second upon putting the hearer into a certain frame of mind, the third upon the speech itself, in so far as it proves or seems to prove.

[4] The orator persuades by moral character when his speech is delivered in such a manner as to render him worthy of confidence; for we feel confidence in a greater degree and more readily in persons of worth in regard to everything in general, but where there is no certainty and there is room for doubt, our confidence is absolute. But this confidence must be due to the speech itself, not to any preconceived idea of the speaker's character; for it is not the case, as some writers of rhetorical treatises lay down in their “Art,” that the worth of the orator in no way contributes to his powers of persuasion; on the contrary, moral character, so to say, constitutes the most effective means of proof. [5] The orator persuades by means of his hearers, when they are roused to emotion by his speech; for the judgements we deliver are not the same when we are influenced by joy or sorrow, love or hate; and it is to this alone that, as we have said, the present-day writers of treatises endeavor to devote their attention. （We will discuss these matters in detail when we come to speak of the emotions.） [6] Lastly, persuasion is produced by the speech itself, when we establish the true
or apparently true from the means of persuasion applicable to each individual subject.

[7] Now, since proofs are effected by these means, it is evident that, to be able to grasp them, a man must be capable of logical reasoning, of studying characters and the virtues, and thirdly the emotions—the nature and character of each, its origin, and the manner in which it is produced. Thus it appears that Rhetoric is as it were an offshoot of Dialectic and of the science of Ethics, which may be reasonably called Politics.¹ That is why Rhetoric assumes² the character of Politics, and those who claim to possess it, partly from ignorance, partly from boastfulness, and partly from other human weaknesses, do the same. For, as we said at the outset, Rhetoric is a sort of division or likeness of Dialectic, since neither of them is a science that deals with the nature of any definite subject, but they are merely faculties of furnishing arguments. We have now said nearly enough about the faculties of these arts and their mutual relations.

[8] But for purposes of demonstration, real or apparent, just as Dialectic possesses two modes of argument,
