Yes, I accept that the leg example doesn't work very well for that reason.

I am not a dualist, at least according to my understanding of the term, but
I have posted separately about that.

No, come on, you said more than that. What you actually said was:

So you didn't tell us the "how", but you *did* claim that we already have
the knowledge of the "how". This was what I called a "truly wild claim".

I think really these are the same questions as elsewhere, so I refer you to
another post which I am just about to send.
