The answer would be yes, of course. All of these are phenomenon. Reality
would continue to unfold, but the universe: the organization of impressions
of reality made by human minds, would cease to exist.

That's a good question. The answer is probably unknown, right now. A human
being's perception definitely can create the universe. I'm not sure what
other minds would create. If we were to communicate with an alien race, they
may not perceive themselves as living in something akin to the universe.
Their minds may be significantly different from ours.
I'm not suggesting that alien races will have the ability to violate the
laws of physics. But, their perceptions may very well be different, and
they may very well probably would not be living in the same perceived
reality as us. Or, our minds may be similar enough so that the phenomena we
observe are virtually identical.

My guess is no, but my real answer is "we just don't know." A similar
question is whether cats have reflective self awarenesses. We just don't
know. We do know that we do not need to posit them having this awareness to
explain their behavior.

My guess is that they don't have reflective self awarnesses.

Well, there are some interesting clues in work that has been done over the
past 50 years. For example, renormalization: do electrons really have
infinite charge? Or, virtual partons...do they really exist? Or, what
happens when we have two formulations of a theory with vastly different
ontological connotations for a realistic perspective; how do we decide which
is right?

You mean, please describe that which is beyond words and beyond our
experiences in 500 words or less? I have no idea and can have no idea what
that's like. Nomenon is simply a word for that which is as it is. One
should assume that words fail to describe it.

Why must a thing be defined by us to exist? He is speaking of that which
exists apart from our mind.

Because we don't have to judge it by a criterion for it to be.

But, its more than that. Back in the mid-1800s it was thought that reality
was going to be "turtles all the way down." (There is a joke associated
with this, I'll tell it if asked. :-) ) That is to say, that the worldview
was that everything could be explained mechanistically.
If we finally got to the point where we could no longer peer into the next
layer of mechanisms, then there would not be a metaphysical problem. We
just would state our basic axioms and be happy with our mechanistic
worldview. But, observations were not consistent with that worldview.

I'm not sure we'd be endlessly frustrated.

Or, just say that's as far as we can see, for now.

That which we cannot define, and exists apart from our observations.

God, if he exists, would be part of the nomenon. The nomenon is sort of a
general catch all for everything that exists without us having direct access
to it. Our own minds have existence, but they are not part of the nomenon.
I don't think Kant got into the question of the minds of other people.

Actually, the last statement is not true at all. One of the most radical
parts of the Critique of Pure Reason is the proposition that God cannot be
arrived at via pure reason. Kant tore apart, rather successfully, the old
proofs of God's existence.
