Is it not more natural and intelligible to draw universal existence from the matter, whose existence is demonstrated by all the senses, and whose effects we experience, which we see act, move, communicate motion, and incessantly generate, than to attribute the formation of things to an unknown power, to a spiritual being, who cannot derive from his nature what he has not himself, and who, by his spiritual essence, can create neither matter nor motion? Nothing is more evident, than that the idea they endeavour to give us, of the action of mind upon matter, represents no object. It is an idea without model.
