This truth may be unfashionable, unpalatable, no doubt unpopular, but, if it is the truth, the story of mankind shows that war was universal and unceasing for millions of years before armaments were invented or armies organized. Indeed, the lucid intervals of peace and order only occurred in human history after armaments in the hands of strong governments have come into being, and civilization in every age has been nursed only in cradles guarded by superior weapons and superior discipline.

Of all the small nations of this earth, perhaps only the ancient Greeks surpass the Scots in their contribution to mankind.

The substitution of the internal combustion engine for the horse marked a very gloomy milestone in the progress of mankind.

No two cities have counted more with mankind than Athens and Jerusalem. Their messages in religion, philosophy, and art have been the main guiding lights of modern faith and culture.

Mankind has never been in this position before. Without having improved appreciably in virtue or enjoying wiser guidance, it has got into its hands for the first time the tools by which it can unfailingly accomplish its own extermination.

Anyone who feels that the problems of mankind can be solved through violence is sleeping through a revolution.
