The first causes of motion are not to be found in matter; matter receives and transmits motion, but does not produce it. The more I observe the action and reaction of the forces of nature playing on one another, the more I see that we must always go back from one effect to another, till we arrive at a first cause in some will; for to assume an infinite succession of causes is to assume that there is no first cause. In a word, no motion which is not caused by another motion can take place, except by a spontaneous, voluntary action; inanimate bodies have no action but motion, and there is no real action without will. This is my first principle. I believe, therefore, that there is a will which sets the universe in motion and gives life to nature. This is my first dogma, or the first article of my creed.
