Embodied intersubjectivity: Forms of psyche-soma structuring in the encounter between self and other-than-self.

Abstract

This paper explores the mechanisms that lead to a destructive tendency in the formation and functioning of the psychic apparatus, to the characteristic states of subjects who are drawn to non-life. The dynamics of the primary mother-child relationship involve a structural interaction between mind and body, subject and object. The dialectic between the life drive and the death drive is conceptualized as the structuring of homeostatic dynamic equilibria, in which both drives belong to the living, provided they are kept in a non-isolated system. This conception has analogies with other disciplines that have changed their paradigms, such as neurobiology, which, for living beings in open systems, hypothesises a continuous interconnected Becoming of undivided separation and of discontinuity. In unitary psyche-soma functioning, a dynamic homoeostatic balance marks the state of health of the relating subject; or if, instead, the system is isolated, a pathological dysregulation depending on the emotional-affective vicissitudes it undergoes. Two clinical cases illustrate these dynamics. For this tendency on the level of the somatopsychic unit, the name alloiosis has been put forward, in analogy with cellular apoptosis.
