[T]he least of the muscular Christians has hold of the old chivalrous and Christian belief, that a man's body is given him to be trained and brought into subjection, and then used for the protection of the weak, the advancement of all righteous causes, and the subduing of the earth which God has given to the children of men. He does not hold that mere strength or activity are in themselves worthy of any respect or worship, or that one man is a bit better than another because he can knock him down or carry a bigger sack of potatoes than he.
