A friend is a person who goes around saying nice things about you behind your back.

All history is but the lengthened shadow of a great man.

The spirit only can teach. Not any profane man, not any sensual, not any liar, not any slave can teach, but only he can give, whohas; he only can create, who is. The man on whom the soul descends, through whom the soul speaks, alone can teach. Courage, piety, love, wisdom, can teach; and every man can open his door to these angels, and they shall bring him the gift of tongues. But the man who aims to speak as books enable, as synods use, as the fashion guides, and as interest commands, babbles. Let him hush.

Society always consists, in greatest part, of young and foolish persons. The old, who have seen through the hypocrisy of the courts and statesmen, die, and leave no wisdom to their sons. They believe their own newspaper, as their fathers did at their age.

We walk alone in the world. Friends, such as we desire, are dreams and fables.

But in our experience, man is cheap and friendship wants its deep sense. We affect to dwell with our friends in their absence, but we do not; when deed, word, or letter comes not, they let us go.

The the illuminated mind the whole world sparkles with light.
