Good acts are like good poems. One may easily get their drift, but they are not rationally understood.

A human being is a part of the whole called by us universe; a part limited in time and space. He experiences himself, his thoughts, and his feelings as something separate from the rest - a kind of optical delusion of consciousness.

If we trace out what we behold and experience through the language of logic, we are doing science; if we show it in forms whose interrelashionships are not accessible to our conscious thought but we are intuitively recognized as meaningful, we are doing art.

For the most part we humans live with the false impression of security and a feeling of being at home in a seemingly familiar and trustworthily physical and human environment. But when the expected course of everyday life is interrupted, we realize that we are like shipwrecked people trying to keep their balance on a miserable plank in the open sea, having forgotten where they came from and not knowing whether they are drifting. But once we fully accept this, life becomes easier and there is no longer any disappointment.

Warfare cannot be humanized.
