Thanks. I might have been moved too much.

Yes, mine seemed to be so too...

I saw it. It suggests the problem might be in the difference between
generations. Important remarks. I might have been pulled to the older-side by my
relatives' death. It is natural that the older genaration is replaced by the
younger, and the means for it is provided by "death."

In the sense of section 5.3.5 of "Quantum Theory and Pictures of Reality" edited
by Schommers, Schommers' thinking seems to agree. But the formulation in the
former section of the book looks different.

In Briggs and Rost paper they seem to think so, but there might be a question on
this point.

Do you mean t in equation (18)?

Could you explain more about the relation between the mind/body dichotonomy and
the sentences you quoted from Briggs and Rost?

I have to ask you more explanation of your idea you mention here.

There is topological difference but it is possible to identify them at least
formally by replacing t by it as is sometimes done in QFT.
