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

As I have tried to show, science, in producing the airplane and the wireless, has created a new international political environment to which governments must adjust their foreign policies.

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.

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

It is said that those whom the gods wish to destroy they first make mad. It may well be that a war neurosis stirred up by propaganda of fear and hatred is the prelude to destruction.

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 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.
