How many roads must a man walk down Before you call him a man? Yes, 'n' how many seas must a white dove sail Before she sleeps in the sand? Yes, 'n' how many times must the cannon balls fly Before they're forever banned? The answer, my friend, is an aphorism, The answer is an aphorism.
The question is not, Can they reason? nor, Can they talk? but, Can they suffer? ~Jeremy Bentham
