Narrative self doesn't do justice to the individual soul. It's more like a condition for appearance, will and counter-will, a life ruled by desires, mostly mimetic and their equally mimetic frustrations. Somehow those constraints give rise to something rather solid-seeming, and the idea that the relative centre is or ought to be the absolute centre, which is the Cartesian error in a nutshell. The anti-Cartesian error is something else again.
