Alright. Personal or 1p experiences are probably outside the realm of
phenomena that can be investigated under Popperian science. I think
this is something that many of us can agree with, independently of
accepting/rejecting comp, for example. I think this is also what
characterises hard-core positivists: they either find 1p reality
irrelevant or even reject its existence.


Which makes sense, since from that kind of fundamentalist 3p perspective, we can only take consciousness for granted. From there, we can either admit or deny that we are taking it for granted, and if we admit it, then we would want to minimize the significance of that.

I don't know! But I think the mystery is not so much how symbols
appear or why they appear. Computers can do that.

Computers don't use symbols.

?


They use physics,

???

You have been less Aristotelian in some other posts.




and the common physics of discrete objects has an arithmetic universality which can be exploited. Computers don't care about symbols though, or output formats.


Nor do brains, in that sense. Only person care on those things, but brain and computer (body) are not person, but person's local vehicle.



The big mystery is
how they become qualia.

That would be a mystery, but it is one that cannot have an answer. In my understanding quanta only makes sense as a derived sampling or 'accounting' of qualia. Objects are aesthetically impoverished feelings.

OK, but then what can we do with "computer use physics". That becomes circular, it seems to me.




Which leads me to a point where I can
definitely agree with you (if I understand you correctly): private
experiences have at least the same reality status as public
experiences. My main problem with your ideas is that I feel you throw
too much of the baby away with the (public) bath water.

I don't think there are any experiences which are public and not private. There are experiences, and there are private experiences in which other private experiences are re-presented as public form- functions.

OK,

Bruno
