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.

As we have seen, the wireless and the airplane have made the world so small and nations so dependent on each other that the only alternative to war is the United States of the World.

Some wars have been due to the lust of rulers for power and glory, or to revenge to wipe out the humiliation of a former defeat.

Some think the worst horrors of war might be avoided by an international agreement not to use atomic bombs. This is a vain hope.

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.

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.
