That is the secret of great art, and of its effect upon us.
The creative process, so far as we are able to follow it at all, consists in the unconscious activation of an archetypal image, and in elaborating and shaping this image into the finished work.
By giving it shape, the artist translates it into the language of the present, and so makes it possible for us to find our way back to the deepest springs of life.
Therein lies the social significance of art: it is constantly at work educating the spirit of the age, conjuring up the forms in which the age is most lacking.
The unsatisfied yearning of the artist reaches back to the primordial image in the unconscious which is best fitted to compensate the inadequacy and one-sidedness of the present
The artist seizes on this image, and in raising it from deepest unconsciousness he brings it into relation with conscious values, thereby transforming it until it can be accepted by the minds of his contemporaries according to their powers.
Peoples and times, like individuals, have their own characteristic tendencies and attitudes.
The very word “attitude” betrays the necessary bias that every marked tendency entails.
Direction implies exclusion, and exclusion means that very many psychic elements that could play their part in life are denied the right to exist because they are incompatible with the general attitude.
The normal man can follow the general trend without injury to himself; but the man who takes to the back streets and alleys because he cannot endure the broad highway will be the first to discover the psychic elements that are waiting to play their part in the life of the collective.
Here the artist’s relative lack of adaptation turns out to his advantage; it enables him to follow his own yearnings far from the beaten path, and to discover what it is that would meet the unconscious needs of his age.
Thus, just as the one-sidedness of the individual’s conscious attitude is corrected by reactions from the unconscious, so art represents a process of self-regulation in the life of nations and epochs. ~Carl Jung, CW 15, Para 130-131
