When it comes in your way to introduce a speech, the first requirement is that it should suit the character both of the speaker and of the occasion; the second is (once more) lucidity; but in these cases you have the counsel’s right of showing your eloquence.

Not so with praise or censure; these should be sparing, cautious, avoiding hypercriticism and producing proofs, always brief, and never intrusive; historical characters are not prisoners on trial. Without these precautions you will share the ill name of Theopompus, who delights in flinging accusations broadcast, makes a business of the thing in fact, and of himself rather a public prosecutor than a historian.

It may occasionally happen that some extraordinary story has to be introduced; it should be simply narrated, without guarantee of its truth, thrown down for any one to make what he can of it; the writer takes no risks and shows no preference.
