“ Man, as a physical being, is governed by invariable laws like other bodies. As an intelligent being, he constantly violates the laws god has established and changes those he himself establishes; he must guide himself, and yet he is a limited being; he is subject to ignorance and error, as are all finite intelligences; he loses even the imperfect knowledge he has. ”
 Montesquieu, The Spirit of Law (1748). copy citation
