Wisdom.... comes not from age, but from education and learning.

Wherever there is degeneration and apathy, there also is sexual perversion, cold depravity, miscarriage, premature old age, grumbling youth, there is a decline in the arts, indifference to science, and injustice in all its forms.

One can prove or refute anything at all with words. Soon people will perfect language technology to such an extent that they'll be proving with mathematical precision that twice two is seven.

If you want to work on your art, work on your life.

I am writing a play which I probably will not finish until the end of November. I am writing it with considerable pleasure, though I sin frightfully against the conventions of the stage. It is a comedy with three female parts, six male, four acts, a landscape (view of the lake), lots of talk on literature, little action and tons of love.

Here I am with you & yet not for a single moment do I forget that there's an unfinished novel waiting for me.

Cross out as many adjectives and adverbs as you can. ... It is comprehensible when I write: "The man sat on the grass," because it is clear and does not detain one's attention. On the other hand, it is difficult to figure out and hard on the brain if I write: "The tall, narrow-chested man of medium height and with a red beard sat down on the green grass that had already been trampled down by the pedestrians, sat down silently, looking around timidly and fearfully." The brain can't grasp all that at once, and art must be grasped at once, instantaneously.
