"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."

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

"Measured in time of transport and communication, the whole round globe is now smaller than a small European country was a hundred years ago."

"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."

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

"If the views I have expressed be right, we can think of our civilization evolving with the growth of knowledge from small wandering tribes to large settled law."
