Stephen: Thanks. I did something wrong again. Forgive me. The lower half of
the body has just disappeared. The whole body is attached below. May it
survive as a healthy one, this time! Koichiro.

Dilation (e.g., association of quantum histories with quantum states) and
reduction (e.g., back to 3(4)-d space) are operations or processes. The
problem set to myself is what could be the reference against which these are
said to be operations or processes. I am not familiar with empirical or
causal implications of the Kaehler action.

My reference to what the present progressive and the present perfect look
like is from Aristotle.
"For every movement is incomplete - making thin, learning, walking,
building, these are movements, and incomplete at that. For it is not true
that at the same time a thing is walking and has walked, or is building and
has built, or is coming to be and has come to be, or being moved and has
been moved, but what is being moved is different from what has been moved,
and what is moving from what has moved. But it is the same thing that at the
same time has seen and is seeing, is thinking and has thought. The latter
sort of process, then, I call actuality, and the former a movement."
(Metaphysics Book IX, Chap. 6, 1048b)
