Such a State runs the danger not only of losing a valuable part of its population by emigration, but of also gradually falling from its supremacy in the civilized and political world through diminishing production and lessened profits.
In this respect we stand to-day at the threshold of a development.

We cannot reject the possibility that a State, under the necessity of providing remunerative work for its population, may be driven into war.
If more valuable advantages than even now is the case had been at stake in Morocco, and had our export trade been seriously menaced, Germany would hardly have conceded to France the most favourable position in the Morocco market without a struggle.

England, doubtless, would not shrink from a war to the knife, just as she fought for the ownership of the South African goldfields and diamond-mines, if any attack threatened her Indian market, the control of which is the foundation of her world sovereignty.

The knowledge, therefore, that war depends on biological laws leads to the conclusion that every attempt to exclude it from international relations must be demonstrably untenable.

But it is not only a biological law, but a moral obligation, and, as such, an indispensable factor in civilization.
The attitude which is adopted towards this idea is closely connected with the view of life generally.
If we regard the life of the individual or of the nation as something purely material, as an incident which terminates in death and outward decay, we must logically consider that the highest goal which man can attain is the enjoyment of the most happy life and the greatest possible diminution of all bodily suffering.
