Yes, that’s all interesting speculation, but i was talking about something non-philosophic, non-speculative, purely scientific.

It’s very simple — people like Sean Carroll, a physicist, chooses physicalism or materialism as a belief system, and thinks that he is doing so on the basis of current scientific methodology.

I’m just pointing to an extremely simple thing — that science, as currently accepted, provides not a single bit of evidence that anything purely physical exists.

That’s all. Because this is so difficult for people to understand, I suggest the following thought-experiment:

Try to conceive of a scientific experiment that would provide even the tiniest evidence that something purely physical (that is, some kind of stuff, whether subatomic particles, fields or whatever) that exists independently of any kind of (not necessarily human) awareness or consciousness.

I can’t conceive of how such an experiment would be carried out. But perhaps you can — can you think of how such an experiment might look?
