[A] planet, wholly inhabited by spiders, (which is very possible) - David Hume

Weakness, fear, melancholy, together with ignorance, are, therefore, the true sources of Superstition.

There is an inconvenience which attends all abstruse reasoning. That it may silence, without convincing an antagonist, and requires the same intense study to make us sensible of its force, that was at first requisite for its invention. When we leave our closet, and engage in the common affairs of life, its conclusions seem to vanish, like the phantoms of the night on the appearance of the morning; and 'tis difficult for us to retain even that conviction, which we had attain'd with difficulty.

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.
