I agree.

Sure.

Absolutely so.

I guess you agree that we can hope or bet on some relations between
them;
Note also that there is "reality", "perception of reality", "belief on
reality", "knowledge",
sharable and un-sharable, etc. All this is already discussed in details
in Plato, among others.

To much definition can make things clumsy, but some definition can help
people to realize that they were not arguing on the same things.
Definition should always avoid the 1004 fallacy, i.e. not being more
precise than the level of precision of the reasoning.

Excellent. Although I would say that those who actually go about their
business in world are the philosophers. But so-called "philosophy"
suffers, like religion and even unions, from human institutionalization
which just kill the spirit.

OK. (note in passing the use of material implication!)

Could depend on what.

Nor should we confuse reality with the interpretation of theories that
we build from those perceptions and experiments. But we must take
seriously those theories if only to be able to be refuted and to
progress toward closer approximation of that reality. This needs works.
