C.N. Douglas, comp. Forty Thousand Quotations: Prose and Poetical. 1917.
Nothing conveys a more inaccurate idea of a whole truth than a part of a truth so prominently brought forth as to throw the other parts into shadow. This is the art of caricature; and by the happy use of that art you might caricature the Apollo Belvidere.
A farce is that in poetry which grotesque (caricature) is in painting. The persons and actions of a farce are all unnatural, and the manners false, that is, inconsistent with the characters of mankind; and grotesque painting is the just resemblance of this.
The great moral satirist, Hogarth, was once drawing in a room where many of his friends were assembled, and among them my mother. She was then a very young woman. As she stood by Hogarth, she expressed a wish to learn to draw caricature. Alas, young lady, said Hogarth, it is not a faculty to be envied! Take my advice, and never draw caricature; by the long practice of it, I have lost the enjoyment of beauty. I never see a face but distorted; I never have the satisfaction to behold the human face divine. We may suppose that such language from Hogarth would come with great effect: his manner was very earnest, and the confession is well deserving of remembrance.
