No tribe unites with another of its own free will.

Civilization never stands still; if in one country it is falling back, in another it is changing, evolving, becoming more complicated, bringing fresh experience to body and mind, breeding new desires, and exploiting Nature's cupboard for their satisfaction.

Evolution is unproved and unprovable. We believe it only because the only alternative is special creation, and that is unthinkable.

The main force used in the evolving world of humanity has hitherto been applied in the form of war.

This world of ours has been constructed like a superbly written novel: we pursue the tale with avidity, hoping to discover the plot.

No tempting form of error is without some latent charm derived from truth.

Under no stretch of imagination can war be regarded as an ethical process; yet war, force, terror, and propaganda were the evolutionary means employed to weld the German people into a tribal whole.
