Courage comes naturally to those who have the habit of facing labor and danger, and who therefore know the power of their arms and bodies; and courage or confidence in the mind comes to those who know by use its wonderful forces and inspirations and returns. Belief in its future is a reward kept only for those who use it. "To me," said Goethe, "the eternal existence of my soul is proved from my idea of activity. If I work incessantly till my death, nature is bound to give me another form of existence, when the present can no longer sustain my spirit." It is a proverb of the world that good-will makes intelligence, that goodness itself is an eye; and the one doctrine in which all religions agree, is that new light is added to the mind in proportion as it uses that which it has. "He that doeth the will of God abideth forever." Ignorant people confound reverence for the intuitions with egotism. There is no confusion in the things themselves. Health of mind consists in the perception of law. Its dignity consists in being under the law. Its goodness is the most generous extension of our private interests to the dignity and generosity of ideas. Nothing seems to me so excellent as a belief in the laws. It communicates nobleness, and, as it were, an asylum in temples to the loyal soul. I confess that everything connected with our personality fails. Nature never spares the individual. We are always balked of a complete success. No prosperity is promised to _that_. We have our indemnity only in the success of that to which we belong. _That_ is immortal and we only through that. The soul stipulates for no private good. That which is private I see not to be good. "If truth live, I live; if justice live, I live," said one of the old saints, "and these by any man's suffering are enlarged and enthroned." The moral sentiment measures itself by sacrifice. It risks or ruins property, health, life itself, without hesitation, for its thought, and all men justify the man by their praise for this act. And Mahomet in the same mind declared, "Not dead but living ye are to account all those who are slain in the way of God."
