A hungry dog believes in nothing but meat.

A good person will feel guilty even before a dog.

In two or three hundred years life on earth will be unimaginably beautiful, astounding. Man needs such a life and if it hasn't yetappeared, he should begin to anticipate it, wait for it, dream about it, prepare for it. To achieve this, he has to see and know more than did his grandfather and father.

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.

I think that it would be less difficult to live eternally than to be deprived of sleep throughout life.

If an intelligent, educated, and healthy man begins to complain of his lot and go down-hill, there is nothing for him to do but to go on down until he reaches the bottom--there is no hope for him. Where could my salvation come from? How can I save myself? I cannot drink, because it makes my head ache. I never could write bad poetry. I cannot pray for strength and see anything lofty in the languor of my soul. Laziness is laziness and weakness weakness. I can find no other names for them. I am lost, I am lost; there is no doubt of that.

One must speak about serious things seriously.
