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.
Whenever we encounter the Infinite in man, however imperfectly understood, we treat it with respect. Whether in the synagogue, the mosque, the pagoda, or the wigwam, there is a hideous aspect which we execrate and a sublime aspect which we venerate. So great a subject for spiritual contemplation, such measureless dreaming - the echo of God on the human wall!
