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.

What then in the last resort are the truths of mankind? They are the irrefutable errors of mankind.

When our universe is in harmony with man, the eternal, we know it as truth, we feel it as beauty.

Words are but symbols for the relations of things to one another and to us; nowhere do they touch upon absolute truth.

On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.

Convictions are more dangerous foes of truth than lies.
