…’a god plus the universe requires two substances’. This, of course, depends entirely upon what is meant by ‘universe’. Above we have FattyCatty concluding that ‘universe’ = God. It is at least interesting to note the conclusions of recent research (discussed a while back on another JREF thread) that accurately point out that particles are informational in nature and their physical form is a derived state. The most parsimonious interpretation of this ‘metaphorical’ understanding of ultimate reality could arguably be addressed as follows (taken from another JREF discussion many moons ago):
All you really know about the universe and all therein is that it's objectively independent of you in some way (realism) and that it works just fine according to chemical/physical laws and processes (naturalism).
But that's all you know. You don't know what its ultimate nature is.
Furthermore, as soon as you accept that all the things we experience about the universe are filtered through our senses - which they are - you're accepting that we can never truly know the ultimate nature of neumenal reality.
So I'm left to wonder. We have:
A) A magical self-perpetuating and self-generating non-conscious powder or power behind it all.
Or
B) A magical self-perpetuationg and self-generating consciousness behind it all.
Without any way to conclusively answer the question I'm wondering why you don't just apply Occam's razor instead of multiplying unknown entities?
Consciousness can create, store and retrieve information and we all, intimately and directly, know that consciousness exists.
Is it really logical to assume that a Universe (composed ultimately, of massless wavy-gravy information) is more likely produced by an unknown thing (that is pure conjecture) than a consciousness which has a firm theoretical grounding being based upon something we do know exists (i.e. our own individual consciousnesses)?
....parsimony is in the eye of the beholder.
Answers to the above take a while, but here goes.......
As to parsimony, as I have stated several times this god is entirely non-parsimonious. There are two reasons to reject this god on reasonable grounds -- one, it requires magic to make sense and magic is, by definition, what does not make sense; and two, there is no reason to suggest such a god. It is simply possible.
From what I can see there are four types of god of which we can make some sort of sense. One is the caretaker god mentioned above, but it has clear problems. One is the deist god, but it is inconsequential. One is the pantheist god, also inconsequential. And the other is the idealist god which you bring up.
I do not accept the argument that idealism makes more sense than 'materialism' for the following reasons:
1. The argument you make is based on analogy. The only consciousness of which we are aware is our consciousness, and all the evidence we have of this type of consciousness indicates that it is based on material action (atoms banging around). Stop the functioning of the brain and thinking ceases. Of course you can propose an answer to that issue, but then you multiply problems because you would have to say that the brain is simply a receiver of the Conscious Mind; and if you've made that move you've stepped head first into substance dualism. If we're going to deal with substance dualism why not go all the way and invoke Yahweh?
2. If you analyze what we mean by consciousness it is based in thought or mental action of some sort; it unfolds (that is the kind of consciousness that we know exists). Some people try to define Awareness as simply existing in the moment to try to get around this, but it is not clear that even makes sense. So, what we are left with is an action -- mental activity of some sort -- that unfolds in time. If that is the case, then Awareness in the moment cannot be the primary substance itself. Whatever energy it 'uses' and time (let's call it space-time just for chuckles) would be more fundamental. So, now we're back at time and energy.
Since you are using an analogic argument, we are stuck with the kind of consciousness which we know as the basis for the analogy. The kind of consciousness that we know suggests something more primary than it. If you want to propose another type of consciousness, then the analogy falls apart and you're stuck in the same position -- something we can't know as the basis of it all.
If you want to believe that everything consists of thoughts in the mind of god, that's fine with me; but I don't think we should pretend that is more likely than any alternative explanation for what *is*.
I'll repeat now what I've said several times before -- we can't get to basic ontology. The language argument against it should be good enough to show why it is not possible. Something exists. That's all we can say.
