Not only the warrior in the field but his friends at home will often bridle their sensual appetites from a belief that by so doing they will the more easily overcome their enemies.[410] The fallacy of such a belief, like the belief that the chastity of the sower conduces to the growth of the seed, is plain enough to us; yet perhaps the self-restraint which these and the like beliefs, vain and false as they are, have imposed on mankind, has not been without its utility in bracing and strengthening the breed. For strength of character in the race as in the individual consists mainly in the power of sacrificing the present to the future, of disregarding the immediate temptations of ephemeral pleasure for more distant and lasting sources of satisfaction. The more the power is exercised the higher and stronger becomes the character; till the height of heroism is reached in men who renounce the pleasures of life and even life itself for the sake of keeping or winning for others, perhaps in distant ages, the blessings of freedom and truth.
