The business of finding a nation's soul is a long and slow one at the best and a great many prophets must be slain in the course of it. Perhaps when we have slain enough prophets future generations will begin to build their tombs. Ralph Vaughan Williams
Conflict, not progress, is the word that defines man's path from darkness into light. No holiness is won by any other means than this, that wickedness should be slain day by day, and hour by hour. Alexander Maclaren
For human laws and laws divine ordain, Who slays another, shall himself be slain. Ludovico Ariosto
For he who reckons it a pleasure that a man, though justly condemned, should be slain in his sight, pollutes his conscience as much as if he should become a spectator and a sharer of a homicide which is secretly committed. Lactantius
