“Providence has relation essentially to man. It is for man's sake that Providence makes of things whatever it pleases; it is for man's sake that it supersedes the authority and reality of a law otherwise omnipotent. … [W]e nowhere read that God, for the sake of brutes, became a brute – the very idea of this is, in the eyes of religion, impious and ungodly; or that God ever performed a miracle for the sake of animals or plants.
