David Hume, Of the Standard of Taste, 1760
Variant: The admirers and followers of the Alcoran insist on the excellent moral precepts interspersed through that wild and absurd performance. But it is to be supposed, that the Arabic words, which correspond to the English, equity, justice, temperance, meekness, charity were such as, from the constant use of that tongue, must always be taken in a good sense; and it would have argued the greatest ignorance, not of morals, but of language, to have mentioned them with any epithets, besides those of applause and approbation. But would we know, whether the pretended prophet had really attained a just sentiment of morals? Let us attend to his narration; and we shall soon find, that he bestows praise on such instances of treachery, inhumanity, cruelty, revenge, bigotry, as are utterly incompatible with civilized society. No steady rule of right seems there to be attended to; and every action is blamed or praised, so far only as it is beneficial or hurtful to the true believers.
