Art is the most complex, vitalizing and civilizing of human actions. Thus it is of biological necessity. Art sensitizes man to the best that is immanent in him through an intensified expression involving many layers of experience. Out of them art forms a unified manifestation, like dreams which are composed of the most diverse source material subconsciously crystallized. It tries to produce a balance of the social, intellectual and emotional existence; a synthesis of attitudes and opinions, fears and hopes. Art has two faces, the biological and the social, the one toward the individual and the other toward the group. By expressing fundamental validities and common problems, art can produce a feeling of coherence. This is its social function which leads to a cultural synthesis as well as to a continuation of human civilization. Today, lacking the patterning and refinement of emotional impulses through the arts, uncontrolled, inarticulate and brutally destructive ways of release have become commonplace. Unused energies, subconscious frustrations, create the psychopathic borderline cases of neurosis. Art as expression of the individual can be a remedy of sublimation of aggressive impulses. Art educates the receptive faculties and it revitalises the creative abilities. In this way art is rehabilitation therapy through which confidence in one’s creative abilities can be restored.
