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
On Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much - the wheel, New York, wars and so on, whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man - for precisely the same reasons. -HHGTTG
