Our civilization has evolved through the continuous adjustment of society to the stimulus of new knowledge.

We are now physically, politically, and economically one world and nations so interdependent that the absolute national sovereignty of nations is no longer possible.

In recent times, European nations, with the use of gunpowder and other technical improvements in warfare, controlled practically the whole world. One, the British Empire, brought under one government a quarter of the earth and its inhabitants.

In the last fifty years science has advanced more than in the 2,000 previous years and given mankind greater powers over the forces of nature than the ancients ascribed to their gods.

The history of our civilization has been one of intermittent war.

The real evil of the Russian communist state is not communism. It is the secret police and the concentration camp.

When the fabric of society is so rigid that it cannot change quickly enough, adjustments are achieved by social unrest and revolutions.
