“Feebleness of will brings about weakness of head, and the abyss, in spite of its horror, comes to fascinate us, as though it were a place of refuge. Terrible danger!

“Society lives by faith, and develops by science.”

“A belief is not true because it is useful”

“Dare to be what you are, and learn to resign with a good grace all that you are not and to believe in your own individuality.”

“Truth is not only violated by falsehood;it may be outraged by silence.”
