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.

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.

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

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.

Nearly every country in the world is now becoming industrialized as rapidly as it can.

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.

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