The paper reviews the course of the controversy surrounding Jung's theory of archetypes beginning in the mid 1990s and continuing to the present. Much of this controversy was concerned with the debate between the essentialism of the evolutionary position of Anthony Stevens as found in his 1983 book Archetypes: A Natural History of the Self, and the emergence model of the archetypes proposed in various publications by Hogenson, Knox and Merchant, among others. The paper then moves on to a consideration of more recent developments in theory, particularly as derived from an examination of the philosopher Gilles Deleuze, who introduces Bergson's somnambulistic unconscious into the discussion of Jung's theories. It is suggested that this largely unexamined influence on Jung may provide answers to some of the unanswered questions surrounding his theorizing. The paper concludes by suggesting that the notion of the somnambulistic unconscious may resemble Atmanspacher's argument for a dual-aspect monism interpretation of Jung.
