After thus stating the principles of morality, in the "Secunda Secundae," St. Thomas comes to a minute exposition of his ethics according to the scheme of the virtues. The conceptions of faith and love are of much significance in the complete system of St. Thomas. Man strives toward the highest good with the will or through love; but since the end must first be "apprehended in the intellect," knowledge of the end to be loved must precede love; "because the will can not strive after God in perfect love unless the intellect have true faith toward him."
