David Hume on Human Conceptions of God
The Natural History of Religion (1757), Part XV.
The universal propensity to believe in invisible, intelligent power, if not an original instinct, being at least a general attendant of human nature, may be considered as a kind of mark or stamp, which the divine workman has set upon his work; and nothing surely can more dignify mankind, than to be thus selected from all other parts of the creation, and to bear the image or impression of the universal Creator. But consult this image, as it appears in the popular religions of the world. How is the deity disfigured in our representations of him! What caprice, absurdity, and immorality are attributed to him! How much is he degraded even below the character, which we should naturally, in common life, ascribe to a man of sense and virtue!
... What a noble privilege is it of human reason to attain the knowledge of the supreme Being; and, from the visible works of nature, be enabled to infer so sublime a principle as its supreme Creator? But turn the reverse of the medal. Survey most nations and most ages. Examine the religious principles, which have, in fact, prevailed in the world. You will scarcely be persuaded, that they are any thing but sick men's dreams: Or perhaps will regard them more as the playsome whimsies of monkies in human shape, than the serious, positive, dogmatical asseverations of a being, who dignifies himself with the name of rational.
