In no passage of the holy canonical books there can be found either divine precept or permission to take away our own life, whether for the sake of entering on the enjoyment of immortality, or of shunning, or ridding ourselves of anything whatever. Nay, the law, rightly interpreted, even prohibits suicide, where it says, 'Thou shalt not kill.' This is proved especially by the omission of the words "thy neighbor," which are inserted when false witness is forbidden.
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 AugustineDisturbers are to be rebuked, the low spirited to be encouraged, the infirm to be supported, objectors confuted, the treacherous guarded against, the unskilled taught, the lazy aroused, the contentious restrained, the haughty repressed, the poor relieved, the oppressed liberated, the good approved, the evil borne with, and all are to be loved!
