Mysticism isn't the inevitable result. Our observations certainly exist, even if they are uncaused and fundamental. They certainly seem to have a certain order and consistency, even if there is no real reason for this. The scientific method can still be applied to look for and analyze recurring patterns in our observations, and it makes as much sense to do this as not.

Okay, an underlying objective reality causes the order in what we experience - but then what causes the order in this underlying objective reality? You haven't answered any questions...you've just rephrased them in a way that suggests that they've been answered. What causes the order that we experience? Objective Reality. What is Objective Reality? That which causes the order we experience.

If I take a radioactive decay source, map the decay events into an 4 bit number, then look for a sequence of 1000 numbers in which the number "0" comes up 90% of the time (instead of 6.25% of the time as would be expected for a uniform distribution), I will never, ever, ever observe this relative frequency? And there is a 0% chance that the very first 1000 numbers will exhibit this relative frequency? As I said, given enough time and enough attempts, it would seem to be inevitable. And this would hold equally true for sample sizes of 10000, or 100000, or whatever. You'd just have to wait longer (probably). So, if we waiting long enough (very very very very very long), eventually we should see a 1000 year period where the randomness of a particular radioactive decay source was disconfirmed...it would not be observed as obeying Poisson statistics, right? >> Well…ultimately, nothing can explain >> it.

An "ultimate explanation" I guess would be a final explanation, the last bit of information that can (even in principle) be provided which is relevant to the question posed. I'd say that "there is no reason for it, it just is that way" is pretty final. And, for me at least, does produce some feeling of understanding. >> In other words, what caused the cause of my orderly perceptions? And >> what caused that cause?

I don't see why anything has to be reformulated in terms of conscious events. Our conscious experiences exist. There are recurring patterns to what we observe. Cognitively, it helps to "objectify" these recurring patterns as real things. Fine. But the fact that it's (contingently) helpful to think this way doesn't mean that you're justified in ascribing actual existence to your theoretical constructs. This goes for chairs and neighbors as well as electrons and quarks. >> and that science is only about constructing plausible >> narratives that are consistent with past observations…not about an >> unexplained and inexplicable independently existing world made of >> mysterious substances referred to as “matter”. >> > > If you assume it is only description of past observations then you have > assumed it has no predictive power and it is useless. I don't see how it would make any difference. There is no better strategy than to look for patterns in the records of our past observations and act as if those patterns will continue to hold true in the future. Regardless of what really exists, or how things really are, this is the most rational approach. EVEN IF reality is totally random, and we’ve just been on a lucky streak, there is STILL no better strategy than to continue to bet as though that lucky streak will hold, right? At least, given the fact that "not betting" isn't really an option... > I suggest you do not > fly on any airliner designed by engineers with this philosophy. Again, while I have the subjective feeling of choice as to whether I get on the airliner, in fact I'm going to do whatever is entailed by the underlying nature of reality. >> So obviously what we *know* are these relations between sense >> perceptions.

I know that my experiences exist...to the extent that I know anything at all. Though from these experiences I can't conclude anything definite about my actual nature.
