Some of that dreary double entendre may be attributed to freer times and manners than ours, but not all. The foul Satyr's eyes leer out of the leaves constantly: the last words the famous author wrote were bad and wicked—the last lines the poor stricken wretch penned were for pity and pardon. I think of these past writers and of one who lives amongst us now, and am grateful for the innocent laughter and the sweet and unsullied page which the author of "David Copperfield" gives to my children.
snuffs a candle with his fingers for the first time, or better still, perhaps, like that trembling daring with which a child touches a hot tea-urn, because it has been forbidden; so that the mind has its own white and black angel; the same or similar amusement as may be supposed to take place between an old debauchee and a prude,—the feeling resentment, on the one hand, from a prudential anxiety to preserve appearances and have a character; and, on the other, an inward sympathy with the enemy. We have only to suppose society innocent, and then nine-tenths of this sort of wit would be like a stone that falls in snow, making no sound, because exciting no resistance; the remainder rests on its being an offence against the good manners of human nature itself.
"This source, unworthy as it is, may doubtless be combined with wit, drollery, fancy, and even humour; and we have only to regret the misalliance; but that the latter are quite distinct from the former, may be made evident by abstracting in our imagination the morality of the characters of Mr. Shandy, my Uncle Toby, and Trim, which are all antagonists to this spurious sort of wit, from the rest of 'Tristram Shandy,' and by supposing, instead of them, the presence of two or three callous debauchees. The result will be pure disgust. Sterne cannot be too severely censured for thus using the best dispositions of our nature as the panders and condiments for the basest."—Coleridge, Literary Remains, vol. i. p. 141, 142.
