Dear Prof. Matsuno and Folks,
The quote from Aristotle is great. It is important to see the
difference between a priori potentiality and constructive actuality. The
two different types of infinities well illustrate this! The potentiality
gives the existential possibility and the actual the local
concreteness... They complement each other...
I think that we need to figure out if the notion of space-time fall
within the perview of both!
Later,
Stephen
