The mind must have for ballast the clear conception of duty, if it is not to fluctuate between levity and despair.

He who floats with the current, who does not guide himself according to higher principles, who has no ideal, no convictions-such a man is . . . a thing moved, instead of a living and moving being-an echo, not a voice. The man who has no inner-life is a slave of his surroundings as the barometer is the obedient servant of the air.

There is no curing a sick man who believes himself to be in health.

To live we must conquer incessantly, we must have the courage to be happy.

The ideal, after all, is true than the real: for the ideal is the eternal element in perishable things.

Criticism is above all a gift, an intuition, a matter of tact and flair; it cannot be taught or demonstrated--it is an art. Critical genius means an aptitude for discerning truth under appearances or in disguises which conceal it; for discovering it in spite of the errors of testimony, the frauds of tradition, the dust of time, the loss or alteration of texts. It is the sagacity of the hunter whom nothing deceives for long, and whom no ruse can throw off the trail.

What we call little things are merely the causes of great things; they are the beginning, the embryo, and it is the point of departure which, generally speaking, decides the whole future of an existence. One single black speck may be the beginning of gangrene, of a storm, of a revolution.
