A great many of the impulses which now lead nations to go to war are in themselves essential to any vigorous or progressive life. Without imagination and love of adventure a society soon becomes stagnant and begins to decay. Conflict, provided it is not destructive and brutal, is necessary in order to stimulate men’s activities, and to secure the victory of what is living over what is dead or merely traditional. The wish for the triumph of one’s cause, the sense of solidarity with large bodies of men, are not things which a wise man will wish to destroy. It is only the outcome in death and destruction and hatred that is evil. The problem is, to keep these impulses, without making war the outlet for them.
All Utopias that have hitherto been constructed are intolerably dull….[Utopians] do not realize that much the greater part of a man’s happiness depends upon activity, and only a very small remnant consists in passive enjoyment. Even the pleasures which do consist in enjoyment are only satisfactory, to most men, when they come in the intervals of activity. Social reformers, like inventors of Utopias, are apt to forget this very obvious fact of human nature. They aim rather at securing more leisure, and more opportunity for enjoying it, than at making work itself more satisfactory, more consonant with impulse, and a better outlet for creativeness and the desire to employ one’s faculties.
That is from Principles of Social Reconstruction, 1916. The pointer is from Alex, our Alex.
