Our civilization is now in the transition stage between the age of warring empires and a new age of world unity and peace.

There can be no peace in the world so long as a large proportion of the population lack the necessities of life and believe that a change of the political and economic system will make them available. World peace must be based on world plenty.

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

Science has produced such powerful weapons that in a war between great powers there would be neither victor nor vanquished. Both would be overwhelmed in destruction.

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.

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