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.

Mozart has the classic purity of light and the blue ocean; Beethoven the romantic grandeur which belongs to the storms of air and sea, and while the soul of Mozart seems to dwell on the ethereal peaks of Olympus, that of Beethoven climbs shuddering the storm-beaten sides of a Sinai. Blessed be they both! Each represents a moment of the ideal life, each does us good. Our love is due to both.

The beautiful souls of the world have an art of saintly alchemy, by which bitterness is converted into kindness, the gall of human experience into gentleness, ingratitude into benefits, insults into pardon.

The spirit of sarcasm lives and thrives in the midst of universal wreck; its balls are enchanted and itself invulnerable, and it braves retaliations and reprisals because itself is a mere flash, a bodiless and magical nothing.

Without passion man is a mere latent force and possibility, like the flint which awaits the shock of the iron before it can give forth its spark.

[I]t is truth alone-scientific, established, proved, and rational truth-which is capable of satisfying nowadays the awakened minds of all classes. We may still say perhaps, 'faith governs the world,'-but the faith of the present is no longer in revelation or in the priest-it is in reason and in science.

Philosophy starts with doubt and loves only truth.
