Plato,
Laws — The Preamble
(1875)
“ For if the law will not allow a man to kill the authors of his being even in self-defence, what other penalty than death can be inflicted upon him who in a fit of passion wilfully slays his father or mother? If a brother kill a brother in self-defence during a civil broil, or a citizen a citizen, or a slave a slave, or a stranger a stranger, let them be free from blame, as he is who slays an enemy in battle. But if a slave kill a freeman, let him be as a parricide. ”
