But the ornaments of sentiments are more important; and because Demosthenes employs them very frequently, some people think that that is the principal thing which makes his eloquence so admirable.  And indeed there is hardly any topic treated by him without a careful arrangement of his sentences; nor indeed is speaking anything else except illuminating all, or at least nearly all, one’s sentences with a kind of brilliancy:  and as you are thoroughly aware of all this, O Brutus, why need I quote names or instances.  I only let the place where they occur be noted.

XL.  If then that consummate orator whom we are looking for, should say that he often treats one and the same thing in many different manners; and dwells a long time on the same idea; and that he often extenuates some point, and often turns something into ridicule; that he occasionally appears to change his intention and vary his sentiments; that he proposes beforehand the points which he wishes to prove; that when he has completed his argument on any subject he terminates it; that he often recals himself back, and repeats what he has already said; that he winds up his arguments with fresh reasons; that he beats down the adversary with questions; again, that he himself answers questions which as it were he himself has put; that he sometimes wishes to be understood as meaning something different from what he says; that he often doubts what he had best say, or how he had best say it; that he arranges what he has to say under different heads; that he leaves out or neglects some points; while there are some which he fortifies beforehand; that he often throws the blame on his adversary for the very thing for which he himself is found fault with; that he often appears to enter into deliberation with his hearers, and sometimes even with his adversary; that he describes the conversation and actions of men; that he introduces some dumb things, as speaking; that he diverts men’s minds from the subject under discussion; that he often turns the discussion into mirth and laughter; that he sometimes preoccupies ground which he sees is attached; that he adduces comparisons; that he cites precedents; that he attributes one thing to one person and another to another; that he checks any one who interrupts him; that he says that he is keeping back something; that he adds threatening warnings of what his hearers must beware of; that he often takes a bolder licence; that he is sometimes even angry; that he sometimes utters reproaches, deprecates calamity, uses the language of supplication, and does away with unfavourable impressions; that he sometimes departs a very little from his subject, to express wishes or to utter execrations, or to make himself a friend of those men before whom he is speaking.

He ought also to aim at other virtues, if I may so call them, in speaking; at brevity, if the subject requires it.  He will often, also, by his speech, bring the matter before people’s eyes; and often extol it beyond what appears possible; his meaning will be often more comprehensive than his speech; he will often assume a cheerful language, and often give an imitation of life and nature.
