In recent years, a growing number of thinkers have begun to challenge the long-held view that the mind is neurally realized. One strand of critique comes from work on extended cognition, a second comes from research on embodied cognition, and a third comes from enactivism. I argue that theorists who embrace the claim that the mind is fully embodied and enactive cannot consistently also embrace the extended mind thesis. This is because once one takes seriously the central tenets of enactivism, it becomes implausible to suppose that life, affectivity, and sense-making can extend. According to enactivism, the entities that enact a world of meaning are autonomous, embodied agents with a concerned point of view. Such agents are spatially situated, differentiated from the environment, and intentionally directed towards things that lie at a distance. While the extended mind thesis blurs the distinction between organism and environment, the central tenets of enactivism emphasize differentiations between the two. In addition, enactivism emphasizes that minded organisms are enduring subjects of action and experience, and thus it is implausible to suppose that they transform into a new form of life whenever they become intimately coupled to some new element in their environment. The proponent of enactivism and embodied cognition should acknowledge that life and affectivity are relational and environmentally embedded, but resist the further claim that these phenomena are extended.

While many theorists have argued that dissociative identity disorder is a case of multiple selves or persons in a single body, I maintain that DID instead should be understood as involving a single self who suffers from significant disruptions to self-consciousness. Evidence of overlapping abilities and memories, as well as the very logic of dissociation, supports the claim that DID results from internal conflict endured by a single self. Along these lines, I will maintain that alter-formation should be understood as the result of extreme emotional ambivalence. While it is true that subjects with DID exhibit volitional conflict, as Frankfurt [1988. The Importance of What We Care About. New York: Cambridge University Press; 1999. Necessity, Volition, and Love. New York: Cambridge University Press] maintains, I argue that these incompatible volitions have a deeper source: conflicting desires and affective stances concerning basic emotional needs that are not easily abandoned. A single subject turns to...
