This litigious humour is bad enough: but there is one character still worse — that of a person who goes into company, not to contradict, but to talk at you. This is the greatest nuisance in civilised society. Such a person does not come armed to defend himself at all points, but to unsettle, if he can, and throw a slur on all your favourite opinions. If he has a notion that anyone in the room is fond of poetry, he immediately volunteers a contemptuous tirade against the idle jingle of verse. If he suspects you have a delight in pictures, he endeavours, not by fair argument, but by a side-wind, to put you out of conceit with so frivolous an art. If you have a taste for music, he does not think much good is to be done by this tickling of the ears. If you speak in praise of a comedy, he does not see the use of wit: if you say you have been to a tragedy, he shakes his head at this mockery of human misery, and thinks it ought to be prohibited. He tries to find out beforehand whatever it is that you take a particular pride or pleasure in, that he may annoy your self-love in the tenderest point (as if he were probing a wound) and make you dissatisfied with yourself and your pursuits for several days afterwards. A person might as well make a practice of throwing out scandalous aspersions against your dearest friends or nearest relations, by way of ingratiating himself into your favour. Such ill-timed impertinence is ‘villainous, and shows a pitiful ambition in the fool that uses it.’

— William Hazlitt, “On the Conversation of Authors,” 1820
