We do not consider patriotism desirable if it contradicts civilized behavior.

Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.

Humor is the mask of wisdom.

Humans need justice in the here and now and grace in the thereafter. Justice in the here and now is possible only without freedom,and grace in the thereafter only through the freedom of God.

Whoever is content with the world, and who profits from its lack of justice, does not want to change it.

A reasonable change of the world can not be instrumented by pure reason.

Every work of art depicts an aspect of reality.
