If it be said, that an Omnipotent Creator, though under no necessity of employing contrivances such as man must use, thought fit to use them in order to leave traces that would enable man to recognize his creative hand, the answer is that this equally implies a limit to his omnipotence. For if he wanted men to know that they themselves and the world are his work, he, being omnipotent, had only to will that they should be aware of it.
