Can we taboo ‘self’? I think I might be working with an incorrect model of what it is, exactly, that you are asserting.
I’m finding it difficult, without positing the existence of myself, to explain some of my observations. For example: all of them.
I think I was able to understand the first two, but the third one just seems to be asserting (unconvincingly: why should a hearer, if it exists, be able to hear itself?) that we are all p-zombies. I’m pretty damn sure that I, as a conscious, introspective, qualia-having, thinking entity, exist, and that is because I have an awareness of myself, and I do not accept that things that don’t exist could have properties such as ‘awareness of self’.
I obviously and definitely exist, because nonexistent entities can’t do the things that I do.
