The defender of large armaments always justifies his position on the ground that such armaments ensure peace. Si vis pacem, etc. As between war and peace he has made his choice, and he has chosen, as the definite object of his endeavors, peace. Having directed his efforts to secure peace, he must accept whatever disadvantages there may lie in that state. He is prepared to admit that, of the two states, peace is preferable, and it is peace towards which our efforts should be directed. Having decided on that aim, what utility is there in showing that it is an undesirable one?

We must, as a matter of fact, be honest for our opponent. We must assume that in an alternative, where his action would determine the issue of war or peace, he will allow that action to be influenced by the general consideration that war might make for the moral advantage of his country. More important even than this consideration is that of the general national temper, to which his philosophy, however little in keeping with his professed policy and desire, necessarily gives rise. For these reasons it is worth while to consider in detail the biological case which he presents.

The illusion underlying that case arises from the indiscriminate application of scientific formulæ.

Struggle is the law of survival with man, as elsewhere, but it is the struggle of man with the universe, not man with man. Dog does not eat dog—even tigers do not live on one another. Both dogs and tigers live upon their prey.

It is true that as against this it is argued that dogs struggle with one another for the same prey—if the supply of food runs short the weakest dog, or the weakest tiger, starves. But an analogy between this state and one in which co-operation is a direct means of increasing the supply of food, obviously breaks down. If dogs and tigers were groups, organized on the basis of the division of labor, even the weak dogs and tigers could, conceivably, perform functions which would increase the food supply of the group as a whole, and, conceivably, their existence would render the security of that supply greater than would their elimination. If to-day a territory like England supports in comfort, a population of 45,000,000, where in other times rival groups, numbering at most two or three millions, found themselves struggling with one another for a bare subsistence, the greater quantity of food and the greater security of the supply is not due to any process of elimination of Wessex men by Northumbrian men, but is due precisely to the fact that this rivalry has been replaced by common action against their prey, the forces of nature. The obvious facts of the development of communities show that there is a progressive replacement of rivalry by co-operation, and that the vitality of the social organism increases in direct ratio to the efficiency of the co-operation, and to the abandonment of the rivalry, between its parts.[52]

All crude analogies between the processes of plant and animal survival and social survival are vitiated, therefore, by disregarding the dynamic element of conscious co-operation.

That mankind as a whole represents the organism and the planet the environment, to which he is more and more adapting himself, is the only conclusion that consorts with the facts. If struggle between men is the true reading of the law of life, those facts are absolutely inexplicable, for he is drifting away from conflict, from the use of physical force, and towards co-operation. This much is unchallengeable, as the facts which follow will show.

But in that case, if struggle for extermination of rivals between men is the law of life, mankind is setting at naught the natural law, and must be on the way to extinction.

Happily the natural law in this matter has been misread. The individual in his sociological aspect is not the complete organism. He who attempts to live without association with his fellows dies. Nor is the nation the complete organism. If Britain attempted to live without co-operation with other nations, half the population would starve. The completer the co-operation the greater the vitality; the more imperfect the co-operation the less the vitality. Now, a body, the various parts of which are so interdependent that without co-ordination vitality is reduced or death ensures, must be regarded, in so far as the functions in question are concerned, not as a collection of rival organisms, but as one. This is in accord with what we know of the character of living organisms in their conflict with environment. The higher the organism, the greater the elaboration and interdependence of its part, the greater the need for co-ordination.[53]

If we take this as the reading of the biological law, the whole thing becomes plain; man's irresistible drift away from conflict and towards co-operation is but the completer adaptation of the organism (man) to its environment (the planet, wild nature), resulting in a more intense vitality.
