One must speak about serious things seriously.

There are plenty of good people, but only a very, very few are precise and disciplined.

We old bachelors smell like dogs, do we? So be it. But I must take issue with your claim that doctors who treat female illnesses are womanizers and cynics at heart. Gynecologists deal with savage prose the likes of which you have never dreamed of.

The unhappy are egoistic, spiteful, unjust, cruel, and less capable of understanding each other than fools. Unhappiness does not bring people together but draws them apart, and even where one would fancy people should be united by the similarity of their sorrow, far more injustice and cruelty is generated than in comparatively placid surroundings.

Do you see that tree? It is dead but it still sways in the wind with the others. I think it would be like that with me. That if I died I would still be part of life in one way or another.

A tree is beautiful, but what's more, it has a right to life; like water, the sun and the stars, it is essential. Life on earth is inconceivable without trees. Forests create climate, climate influences peoples' character, and so on and so forth. There can be neither civilization nor happiness if forests crash down under the axe, if the climate is harsh and severe, if people are also harsh and severe. ... What a terrible future!

Our pride and self-importance are European, while our development and actions are Asiatic.
