Henry Fielding: The History of Tom Jones, a foundling

BOOK VIII. CONTAINING ABOUT TWO DAYS. 1. Chapter i. A wonderful long chapter... (continued)

In the last place, the actions should be such as may not only be within the compass of human agency, and which human agents may probably be supposed to do; but they should be likely for the very actors and characters themselves to have performed; for what may be only wonderful and surprizing in one man, may become improbable, or indeed impossible, when related of another.

This last requisite is what the dramatic critics call conversation of character; and it requires a very extraordinary degree of judgment, and a most exact knowledge of human nature.

It is admirably remarked by a most excellent writer, that zeal can no more hurry a man to act in direct opposition to itself, than a rapid stream can carry a boat against its own current. I will venture to say, that for a man to act in direct contradiction to the dictates of his nature, is, if not impossible, as improbable and as miraculous as anything which can well be conceived. Should the best parts of the story of M. Antoninus be ascribed to Nero, or should the worst incidents of Nero's life be imputed to Antoninus, what would be more shocking to belief than either instance? whereas both these being related of their proper agent, constitute the truly marvellous.

Our modern authors of comedy have fallen almost universally into the error here hinted at; their heroes generally are notorious rogues, and their heroines abandoned jades, during the first four acts; but in the fifth, the former become very worthy gentlemen, and the latter women of virtue and discretion: nor is the writer often so kind as to give himself the least trouble to reconcile or account for this monstrous change and incongruity. There is, indeed, no other reason to be assigned for it, than because the play is drawing to a conclusion; as if it was no less natural in a rogue to repent in the last act of a play, than in the last of his life; which we perceive to be generally the case at Tyburn, a place which might indeed close the scene of some comedies with much propriety, as the heroes in these are most commonly eminent for those very talents which not only bring men to the gallows, but enable them to make an heroic figure when they are there.
