"A man who has faith must be prepared not only to be a martyr, but to be a fool. It is absurd to say that a man is ready to toil and die for his convictions when he is not even ready to wear a wreath round his head for them. I myself, to take a corpus vile, am very certain that I would not read the works of Comte through for any consideration whatever. But I can easily imagine myself with the greatest enthusiasm lighting a bonfire on Darwin Day."
