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.

Many a truth is the result of an error.

Conquer but never triumph.

We should always forgive. We should forgive the repentant for their sake, the unrepentant for our sake.

Oh happy pessimists! What a joy it is to them to be able to prove again and again that there is no joy.

If there is a believe that is capable to move mountains it is the believe in our own strength.

The believer who has never doubted will hardly convert a doubter.
