Weak men are easily put out of humor. Oil freezes quicker than water.

All men are selfish, but the vain man is in love with himself. He admires, like the lover his adored one, everything which to others is indifferent.

The vain being is the really solitary being.

Some men, like modern shops, hang everything in their show windows; when one goes inside, nothing is to be found.

Truly, one gets easier accustomed to a silken bed than to a sack of leaves.

What is all our knowledge worth? We do not even know what the weather will be tomorrow.

It is only when one is thoroughly true that there can be purity and freedom. Falsehood always punishes itself.
