In Dreaming With Open Eyes: The Shamanic Spirit in Twentieth Century Art and Culture, Michael Tucker has compiled a veritable encyclopedia of the literature of shamanism: literal (historic and anthropologic) and metaphorical, and draws compelling connections between the ancient and the bleeding edge. Modern artists working on the fringe of creative boundaries, Tucker argues, strip away some of the filters of contemporary experience and perceive the world in a metaphoric, archetypal way, as Aboriginal dream painters do. The result is art that reaches past the the filters of the consciousness mind to challenge the unconscious mind directly in its native grammar, the language of symbol.
