It is by virtue of contrasts such as this just shown that Fielding would claim to be named among the geniuses.
"By genius I would understand that power, or rather those powers of the mind which are capable of penetrating into all things within our reach and knowledge, and of distinguishing their essential differences. These are no other than invention and judgment...."
Added to this there must be "conversation."
"So necessary is this to the understanding the characters of men that none are more ignorant of them than those learned pedants whose lives have been entirely consumed in colleges and among books; for however exquisitely human nature may have been described by writers, the true practical system can be learnt only in the world."
He also requires of his ideal author "refinement, elegance and liberality of spirit." He must have a good heart and be capable of feeling. "The author who will make me weep," says Horace, "must first weep himself. No man can paint a distress well which he doth not feel while he is painting it.... I am convinced I never make my reader laugh heartily but where I have laughed before him."
Who would deny the interest or importance of digressions like these when they shed such a flood of light on to the author's attitude to his own work?
The sergeant who resented the imputation against his character conveyed by the words non sequitur ("You are another," cries the sergeant, "an you come to that. No more a sequitur than yourself. You are a pack of rascals, and I'll prove it, for I will fight the best man of you all for twenty pounds"); the lightning-like flash of inspiration which made Mrs Waters repeat the cry, "Rape! Rape!" when she is discovered in bed with Tom; the logic of the landlady of the inn ("So easy and good-humoured were they that they found no fault with my Worcestershire perry, which I sold them for champagne; and it, to be sure, is as well tasted, and as wholesome, as the best champagne in the kingdom, otherwise I would scorn to give it 'em; and they drank me two bottles. No, no, I will never believe any harm of such sober, good sort of people")—all these touches and thousands more are proofs of how much genius depends upon "conversation," or a practical knowledge of the world, the power of distinguishing essential differences.
Fielding seems to have distinguished these essential differences not only in people but in the life of his time on every side. Realising full well that posterity would read him, he also realised what were the things that posterity would like to hear about it. So we get that inimitable description of the puppet show where "The Provoked Husband" displaced "Punch and Judy," by the throwing out of which "such idle trumpery puppet-shows were," in the words of their master, "at last brought to be a rational entertainment."
"I would by no means degrade the ingenuity of your profession," answered Jones, "but I should have been glad to have seen my old acquaintance Master Punch for all that; and so far from improving, I think, by leaving him out and his merry wife Joan, you have spoiled your puppet show"—a sentiment that many of us to-day will heartily endorse.
