The sentiment of justice is so natural, and so universally acquired by all mankind, that it seems to be independent of all law, all party, all religion.
VoltaireThere are barbarians who seize this dog, who so prodigiously surpasses man in friendship, and nail him down to a table, and dissect him alive to show you the mezaraic veins... Answer me, Machinist, has Nature really arranged all the springs of feeling in this animal to the end that he might not feel? Has he nerves that he may be incapable of suffering?
Voltaire
