C.g. Jung said this quote

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.
