It is difficult to see that any of the causes of trade war, armament war, or open war are at all likely to be less in the future than they have been in the past; and if the causes are the same we must expect like effects. Nor do we see that any result of these different kinds of war is injurious to that character of man which is requisite for his advance in better lines. Each of these forms of competition tends to give an advantage to the best qualified race, and to promote the most beneficial strains of character. On the general principle that slow evolution is preferable to violent changes we must look for advance by intensified trade war rather than by armaments, and by the strain of armament rather than by open war. A direction in which great improvements of organisation may be attained would be in better adaptation of checks. So far as possible, checks should be abolished by establishing interests in the same direction between different parties. The profit-sharing movement is an excellent beginning of what needs to be fully and exactly carried out. The checks of inspection, which have been so greatly multiplied lately, are peculiarly liable to abuses; and a system of fewer and far superior inspectors, much less inspection, and much heavier penalties to correspond, would in the long run prove the safer line. The great check by popular election is very wasteful, a general election costing the country over a million pounds in various ways. Precisely as fair a check would be gained by summoning one in a hundred of the electors by lot at the day of election; and the nursing of a constituency would be much diminished. Lastly, let us look at the final type to which man will probably be led by natural survival. This enquiry is limited throughout to those qualities which are the product of external causes; and no attempt is made to estimate the more spiritual side of man or his higher mental development. For that we have not the same physical basis of research, and it would be a fruitless mixture to include such considerations—however important—in an enquiry which by its scope might be similarly applicable to lower organisms. We are therefore dealing here only with the physical basis of civilisation. For the sake of safety from aggression and prevention of small quarrels, federations of great size must prevail; while those federations which allow for the greatest diversity between the states will prove more adaptable and vigorous. Similarly, states which allow of the greatest diversity of life to the individual will succeed best, by the promotion of the most vigorous strains. More systematic law will be needed between states. This may perhaps be on the line of all contracts being on the seller's law, and all marriage on the husband's law, regardless of change of residence; and all contracts being suable on their own law in any state.
