A FRAMEWORK FOR APPROACHES TO TRANSFER OF A MIND'S SUBSTRATE

I outline some recent developments in the field of neural prosthesis concerning functional replacement of brain parts. Noting that functional replacement of brain parts could conceivably lead to a form of "mind-substrate transfer" (defined herein), I briefly review other proposed approaches to mind-substrate transfer then I propose a framework in which to place these approaches, classifying them along two axes: top-down versus bottom-up, and on-line versus off-line; I outline a further hypothetical approach suggested by this framework. I argue that underlying technological questions about mind-substrate transfer, there is a fundamental question which concerns our beliefs about continuity of identity.
