Our second mother, habit, is also a good mother. — Berthold Auerbach

"The vain being is the really solitary being."

"Books make men alone for themselves."

"Being alone when one’s belief is firm, is not to be alone."

"Why does it signify to us what they think of us after death, when our being has become only an empty sound?"

"It lies in our own power to attune the mind to cheerfulness."

"What people will say — in these words there lies the tyranny of the world, the whole destruction of our natural disposition, the oblique vision of our minds. These four words bear sway everywhere."
