How can I describe something that doesn't exist? Again, I base my belief that no explanation exists on the following line of reasoning: We have our observations and we want to explain them. To do this, we need some context to place our observations in. So we postulate the existence of an external universe that “causes” our observations. But then we want to explain what caused this external universe…and the only option is to postulate the existence of a much larger multiverse. But then what explains the multiverse? So this leads to the need for an infinite series of ever larger contexts against which to explain the previous context that we used to explain the previous context that we used to explain the fact of our initial observations. So nothing can be explained in terms of only itself. To explain it, you have to place it in the context of something larger. Otherwise, no explanation is possible, and you just have to say, “this is the way it is because that’s the way it is.” Basically it seems to me that there’s only two way the process can end. Two possible answers to the question of “Why do I observe the things that I observe?”: 1) Because things just are the way they are, and there’s no further explanation possible. 2) Because EVERYTHING happens, and so your observations were inevitable in this larger context of “everything”. Do you see some other option? Some flaw in the reasoning? > I refer to my example of vitalism.

When Newton was asked > to explain how gravity did this he replied, "Hypothesi non fingo." Ya, I don't find your vitalism argument convincing at all. We've discussed it before. As for Newton, I quote from one of his letters: "To your second query, I answer, that the motions of which the planets now have could not spring from any natural cause alone, but were impressed by an intelligent Agent." In the Scholium Generale Newton stressed that God was the Lord, Ruler, and Pantocrator of the universe. God ruled the universe note as one rules one's own body, but as a Sovereign Prince.

I'm genuinely curious. To me it looks like your just making some statements about relativity, which while true, have no bearing on my points at all. It seems like you're just throwing in some things that sound good...but don't actually add anything relevant to the discussion. On the other hand, it seems possible that you may tell me something new here. I am interested. >> >> Well...I don't see why we should.

In a deterministic universe, I have no choice in the whether I feel fear or not...it follows from the initial state of the universe plus the causal laws of physics as applied over 13.7 billion years. In a random universe, whether I feel fear or not is an outcome of random processes and thus also not under my control. >> >> And as I've mentioned before, assuming that conscious experience is >> fundamental doesn't preclude making predictions either.

Science is about observation. Conscious experience IS observation. There is no cheating. I'm saying that the same scientific theories could have been developed by using my proposed framework, just as Newton did his work in a very religious theistic framework. > Can you > tell me how, on a consciousness is fundamental model, you would explain the > connection, in terms of conscousness, your ideas cause your fingers to type > things that show up on my monitor? Consciousness is all that exists, and the appearance of causality is just an aspect of that consciousness (I'll follow Kant on this point). So there's nothing to connect. Just narratives to develop that are consistent with what is observed. >> >> But, whether consciousness is fundamental, or matter is fundamental, >> or numbers are fundamental...the only reality that we'll ever *know* >> is the reality of our conscious experience.

I care whether my experiences are pleasant (good) or unpleasant (bad), BUT not whether they're real or dreams. Why should I? As to whether I can tell the difference: When I dream during sleep I almost never know it to be a dream. During some Salvia trips I've been convinced that the Salvia dream is what's real, while my life before it started was all an illusion or a trick of some kind. SO, if my experiences while awake are just yet another kind of dream, I wouldn't know that either, would I? >> And, however things *really* are, there is no reason for it...they >> just are that way. >> > > But you continue to act (and think - except when philosophizing) exactly as > if there were a physical reality.

This is as true assuming physicalism as it is with subjective idealism.
