"As to that which is called nature, it is no other than the laws by which motion and action of every kind, with respect to unintelligible matter, is regulated. And when we speak of looking through nature up to nature's God, we speak philosophically the same rational language as when we speak of looking through human laws up to the power that ordained them. God is the power of first cause, nature is the law, and matter is the subject acted upon. But infidelity by ascribing every phenomenon to properties of matter, conceives a system for which it cannot account, and yet it pretends to demonstration. It reasons from what it sees on the surface of the earth, but it does not carry itself on the solar system existing by motion. It sees upon the surface a perpetual decomposition and recomposition of matter. It sees that an oak produces an acorn, an acorn an oak, a bird an egg, an egg a bird, and so on. In things of this kind it sees something which it calls a natural cause, but none of the causes it sees is the cause of that motion which preserves the solar system."
