Whoever prefers the material comforts of life over intellectual wealth is like the owner of a palace who moves into the servants’ quarters and leaves the sumptuous rooms empty.

Only the thinking man lives his life, the thoughtless man's life passes him by.

Our greatest indulgence towards a man springs from our despair of him.

Beware of the virtue which a man boasts is his.

How happy are the pessimists! What joy is theirs when they have proved there is no joy.

What delights us in visible beauty is the invisible.

Not reading a beautiful book again because you've already read it, that is, as if you were not visiting a dear friend again because you know him already.
