How Our Lives Become Stories: Making Selves

Publisher: Cornell University Press (1999)

[Gerald] Edelman's approach to the brain and to the emergence of consciousness in [his books] is resolutely Darwinian - 'spirits and ghosts are out' (113). His Theory of Neural Group Selection (TNGS) or 'neural Darwinism' articulates his sense of the way in which the brains neural organization is constantly modified - both phylogenetically and ontogenetically - to adapt to the ever-changing demands of experience.

Neural Darwinism has the potential to transform not only traditional conceptions of self but of memory as well, as the work or Israel Rosenfield, formerly Edelman's colleague and collaborator, suggests. Rosenfield believes, first of all, that memories are perceptions newly occurring in the present rather than images fixed and stored in the past and somehow mysteriously recalled to present consciousness. As perceptions, memories share the constructed nature of all brain events that TNGS posits: 'Recollection is a kind of perception...and every context will alter the nature of what is recalled' (Invention 89, emphasis added). Rosenfield's second point about memory, a corollary of his view of memory as embedded in present consciousness, is that all memories are self-referential: 'Every recollection refers not only to the remembered event or person or object but to the person who is remembering' (Strange 42). The bond between self and memory can be traced back to Locke, but Rosenfield puts a new spin on this linkage by factoring in the body as a necessary third term in the equation.

...when we look at life history from the perspective of neural Darwinism, it is fair to say that we are all becoming different persons all the time, we are not what we were; self and memory are emergent, in process, constantly evolving, and both are grounded in the body and the body image. Responding to the flux of self-experience, we instinctively gravitate to identity-support-structures: the notion of identity as continuous over time and the use of autobiographical discourse to record its history.
