The artist is not a person endowed with free will who seeks his own ends, but one who allows art to realize its purposes through him. As a human being he may have moods and a will and personal aims, but as an artist he is ‘man’ in a higher sense – he is ‘collective man’, a vehicle and moulder of the unconscious psychic life of mankind.Carl Jung (from Psychology and Literature, 1930)
