Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.

The freedom of each individual can only be the freedom of all.

Only the freedom of mind can prevent the state from becoming totalitarian and from issuing totalitarian demands.

World history is tragic.

The world is bad but not without hope. It is only hopeless when you look at it from an ideal viewpoint.

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.

Power is paradoxical.

A major power can afford a military debacle only when it looks like a political victory.

Religion and political expediency go beautifully hand in hand.
