It is in the matter of stimulating the energy and resolution of the Government that the psychologist might perhaps differ to some extent from the popular guides of opinion. In getting work out of a living organism it is necessary to determine what is the most efficient stimulus. One can make a man’s muscles contract by stimulating them with an electric battery, but one can never get so energetic a contraction with however strong a current as can be got by the natural stimulus sent out from the man’s brain. Rising to a more complex level, we find that a man does not do work by order so well or so thoroughly as he does work that he desires to do voluntarily. The best way to get our work done is to get the worker to want to do it. The most urgent and potent of all stimuli, then, are those that come from within the man’s soul. It is plain, therefore, that the best way to extract the maximum amount of work from members of a Government—and it is to yield this, at whatever cost to themselves, that they are there—is not by the use of threats and objurgations, by talk of impeachment or dismissal, or by hints of a day of reckoning after the war, but by keeping their souls full of a burning passion of service. Such a supply of mental energy can issue only from a {151} truly homogeneous herd, and it is therefore to the production of such a homogeneity of feeling that we come once more as the one unmistakable responsibility of the civilian. We have seen reason to believe that there was a comparatively favourable opportunity of establishing such a national unity in the early phases of the war, and that the attainment of the same result at this late period is likely to be less easy and more costly of disturbance to the social structure. The simplest basis of unity is equality, and this has been an important factor in the unity which in the past has produced the classically successful manifestations of moral and military power, as for example in the cases of Puritan England and Revolutionary France. Such equality as obtained in these cases was doubtless chiefly moral rather than material, and it can scarcely be questioned that equality of consideration and of fundamental moral estimation is a far more efficient factor than would be equality of material possessions. The fact that it is difficult to persuade a man with thirty shillings a week that he has as much to lose by the loss of national independence as a man with thirty thousand a year, is merely evidence that the imagination of the former is somewhat restricted by his type of education, and that we habitually attach an absurd moral significance to material advantages. It seems certain that it would still be possible to attain a very fair approximation to a real moral equality without any necessary disturbance of the extreme degree of material inequality which our elaborate class segregation has imposed upon us.
