O that men would know themselves to be men; and that he that glorieth would glory in the Lord.
Saint AugustineA Christian man is on his guard with respect to those who philosophize according to the elements of this world, not according to God, by Whom the world itself was made; for he is warned by the precept of the apostle and faithfully hears what has been said, 'Beware that no one deceive you through philosophy and vain deceit, according to the elements of the world'
Saint AugustineThe mind commands the body, and it obeys forthwith; the mind commands itself, and is resisted. The mind commands the hand to be moved, and such readiness is there that the command is scarce to be distinguished from the obedience. Yet the mind is mind, and the hand is body. The mind commands the mind to will, and yet, though it be itself, it obeyeth not. Whence this monstrous thing? and why is it?
Saint Augustine
