Great poetry draws its strength from the life of mankind, and we completely miss its meaning if we try to derive it from personal factors. Whenever the collective unconscious becomes a living experience and is brought upon the conscious outlook of an age, this event is a creative act which is of importance to everyone living at that age. A work of art is produced that contains what may truthfully be called a message to generations of men. So Faust touches something in the soul of every German. So also Dante’s fame is immortal, while The Shepherd of Hermas just failed of inclusion in the New Testament canon. Every period has its bias, its particular prejudice and its psychic ailment. An epoch is like an individual; it has its own limitations of conscious outlook, and therefore requires a compensatory adjustment. This is effected by the collective unconscious in that a poet, a seer or a leader allows himself to be guided by the unexpressed desire of his times and shows the way, by word or deed, to the attainment of that which everyone blindly craves and expects—whether this attainment results in good or evil, the healing of an epoch or its destruction.
--C.G. Jung, Modern Man in Search of a Soul
