However, does not an excess of solidarity, as the Nietzscheans fear, threaten to degenerate man into a sentimental, passive, herd animal? Not at all. The powerful force of competition which, in bourgeois society, has the character of market competition, will not disappear in a socialist society, but, to use the language of psychoanalysis, will be sublimated, that is, will assume a higher and more fertile form. There will be the struggle for one’s opinion, for one’s project, for one’s taste. In the measure in which political struggles will be eliminated – and in a society where there will be no classes, there will be no such struggles – the liberated passions will be channelled into technique, into construction which also includes art. Art then will become more general, will mature, will become tempered, and will become the most perfect method of the progressive building of life in every field. It will not be merely “pretty” without relation to anything else.
All forms of life, such as the cultivation of land, the planning of human habitations, the building of theatres, the methods of socially educating children, the solution of scientific problems, the creation of new styles, will vitally engross all and everybody. People will divide into “parties” over the question of a new gigantic canal, or the distribution of oases in the Sahara (such a question will exist too), over the regulation of the weather and the climate, over a new theatre, over chemical hypotheses, over two competing tendencies in music, and over a best system of sports. Such parties will not be poisoned by the greed of class or caste. All will be equally interested in the success of the whole. The struggle will have a purely ideological character. It will have no running after profits, it will have nothing mean, no betrayals, no bribery, none of the things that form the soul of “competition” in a society divided into classes. But this will in no way hinder the struggle from being absorbing, dramatic and passionate.
And as all problems in a socialist society – the problems of life which formerly were solved spontaneously and automatically, and the problems of art which were in the custody of special priestly castes – will become the property of all people, one can say with certainty that collective interests and passions and individual competition will have the widest scope and the most unlimited opportunity. Art, therefore, will not suffer the lack of any such explosions of collective, nervous energy, and of such collective psychic impulses which make for the creation of new artistic tendencies and for changes in style. It will be the aesthetic schools around which “parties” will collect, that is, associations of temperaments, of tastes and of moods. In a struggle so disinterested and tense, which will take place in a culture whose foundations are steadily rising, the human personality, with its invaluable basic trait of continual discontent, will grow and become polished at all its points. In truth, we have no reason to fear that there will be a decline of individuality or an impoverishment of art in a socialist society ...
