When you say “all of the self can be localised in the brain”, i’m interested in what you mean by “localised”. I get the gist of what you’re trying to say- the brain is where the magic happens, where the information is stored, where it’s processed, everything.

But I have a parallel view that I feel is equally valid, if you interpret it slightly differently. The self can be delocalised outside of the self. A significant part of who or what we consider ourselves to be includes things that lie outside of our physical selves- our culture, for instance.

You could say that it’s encoded or imprinted in our brains, and I agree- but I think of that as a kind of “bookkeeping”. Nobody would say that all of a military or a corporation can be localised in the HQ- I mean, technically that makes sense, but realistically there’s so much more you ought to consider.

Does the self exist if it is not perceived outside of itself? If a tree falls…

I think (but i’m not a neuroscientist, obviously) that the brain needs constant feedback from the external world to make sense of itself. A large part of our development of a sense of self begins when we realise that we can make noises by banging pots and pans. You could say that’s all in the brain, I’m saying that the banging of the pots and pans is directly consequential and cannot be “left out”.
