Belonging to oneself--the whole essence of life lies in that.

Take what you can yourself, and don't let others get you into their hands; to belong to oneself, that is the whole thing in life.

Great God, grant that twice two be not four.

Circumstances define us; they force us onto one road or another, and then they punish us for it.

No matter how often you knock at nature's door, she won't answer in words you can understand--for Nature is dumb. She'll vibrate and moan like a violin, but you mustn't expect a song.

There are some moments in life, some feelings; one can only point to them and pass by.

Nature creates while destroying, and doesn't care whether it creates or destroys as long as life isn't extinguished, as long as death doesn't lose its rights.
