"The efficacy of religion lies precisely in what is not rational, philosophic or eternal; its efficacy lies in the unforeseen, the miraculous, the extraordinary. Thus religion attracts more devotion according as it demands more faith,—that is to say, as it becomes more incredible to the profane mind. The philosopher aspires to explain away all mysteries, to dissolve them into light. Mystery on the other hand is demanded and pursued by the religious instinct; mystery constitutes the essence of worship, the power of proselytism. When the "cross" became the "foolishness" of the cross, it took possession of the masses."

“he who discovers a new world in the depths of the invisible would not do wisely to plant on it a flag known to himself alone, and, like Achilles, "devour his heart in secret;" whether the greatest problems which have ever been guessed on earth had not better have remained buried in the brain which had found the key to them, and whether the deepest thinkers — those whose hand has been boldest in drawing aside the veil, and their eye keenest in fathoming the mysteries beyond it — had not better, like the prophetess of Ilion, have kept for heaven, and heaven only, secrets and mysteries which human tongue cannot truly express, nor human intelligence conceive.”

“Truth is the secret of eloquence and of virtue, the basis of moral authority; it is the highest summit of art and of life.”

“Doing easily what others find difficult is talent; doing what is impossible for talent is genius.”

“In the conduct of life, habits count for more than maxims, because habit is a living maxim, becomes flesh and instinct. To reform one's maxims is nothing: it is but to change the title of the book. To learn new habits is everything, for it is to reach the substance of life. Life is but a tissue of habits.”
