There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.
Men argue, nature acts. -Voltaire
Any coward can fight a battle when he's sure of winning, but give me the man who has pluck to fight when he's sure of losing. That's my way, sir; and there are many victories worse than a defeat. -George Eliot
