Man needs to suffer. When he does not have real griefs he creates them.

To beautify life is to give it an object.

Every human being has within him an ideal man, just as every piece of marble contains in a rough state a statue as beautiful as the one that Praxiteles the Greek made of the god Apollo.

Just as he who gives his life to serve a great idea is admirable, he who avails himself of a great idea to serve his personal hopes of glory and power is abominable, even if he too risks his life.

It is a sin not to do what one is capable of doing.

Men are products, expressions, reflections; they live to the extent that they coincide with their epoch, or to the extent that they differ markedly from it.

A child who does not think about what happens around him and is content with living without wondering whether he lives honestly is like a man who lives from a scoundrel's work and is on the road to being a scoundrel.
