To crush out fanaticism and revere the infinite, such is the law. Let us not confine ourselves to falling prostrate beneath the tree of creation and contemplating its vast ramifications full of stars. We have a duty to perform, to cultivate the human soul, to defend mystery against miracle, to adore the incomprehensible and to reject the absurd; to admit nothing that is inexplicable excepting what is necessary, to purify faith and obliterate superstition from the face of religion, to remove the vermin from the garden of God.
There exists, at the bottom of all abasement and misfortune, a last extreme which rebels and joins battle with the forces of law and respectability in a desperate struggle, waged partly by cunning and partly by violence, at once sick and ferocious, in which it attacks the prevailing social order with the pin-pricks of vice and the hammer-blows of crime.

Are there not here unsounded depths for the thinker? Is one to think oneself mad because one has the sentiment of universal pity in one's heart?
