It's looking more and more like we are as programmed as any other lower animal but with higher level behaviors. For instance: your dog doesn't know how the tap water gets to your kitchen sink (maybe you don't either) but we humans do, though we don't know how the Universe was created, some day we might when we learn enough.

    This does stand to be interesting to robotics. If you sit down to figure out the algorithm to get a robot out of a tight spot, 'a spark of free will' might be very VERY useful. The simple randomness of such might be what keeps most of us out of trouble most of the time anyway... we just don't realize it, or worse, we blame it on a deity?

    Or maybe your essentially newtonian and deterministic view of reality is based on assumptions which conveniently can never be proven or disproven. You know, just like crazy religious people.

    I mean, does it even occur to you that if you could, somehow, recreate the *exact* same state of affairs twice to see what would happen, then it might still be possible for two different outcomes to occur? Not because of anything measurable or predictable, but because that's just how things are?

    If you think "physics" or, for that matter, "reality" is all newtonian levers and collisions then you will no doubt say that it's impossible. But if reality simply doesn't behave like that then you might be wrong, and you couldn't prove it one way or another.

    To take one, limited example: what if in a given situation a whole range of outcomes happen, but the infinite number of different outcomes lead to an infinite number of different, quasi-parallel universes? Simply because your consciousness is limited to observing one of these at a time doesn't mean that it's "the only thing which could have happened", does it? However, to you, there is only one, seemingly consistent, version of reality. I'm sure there are problems with this example but perhaps it conveys the essential point.

      You were on a roll up to this point. But here you seem to be falling for a different brand of question begging: you are tacitly assuming that there is "a reason" for things to be the way they are. So far the best explanation IMHO is another tautology... Things are the way they are, because that's the way they are.

      That's the gripe with science that rational religious people have (and yes, they do exist), science can conceivably tell you how the universe works but can't tell you WHY it works that way. To speculate on the motivation for things to be the way they are is outside of the realm of science. Some people dislike this and they look for explanations in meta(beyond) physics. So basically you have to big trends, either the universe "just happened" or it was somehow made. Science could tell you down to the very last quark how the universe works in either case, it doesn't matter to it whether something put it together like this or it was just a Big Freak Accident as long as there are strings of cause and effect leading from "A" to "B" to "C" and so forth.

      Conceivably if the universe was made, and The Maker tweaked it at random here and there —i.e. by performing miracles— that would thwart science's efforts to explain things because it relies on repeatability and pattern-finding. But experience so far tell us that our reality has stable behavior that doesn't change in unpredictable ways. That doesn't rule out the possibility of a maker behind curtains, for all we know s/he/it may be tweaking the world and still staying within its rules. But science won't be able to distinguish intent from random accident because it operates from inside the environment and whether the "rules" were placed or they just sprung from nowhere, they still bind it.

      Some people dislike this and they look for explanations in meta(beyond) physics."

      They can just as easily say that some people don't like the uncaring universe that science reveals, and that's why they run to religion.

      Which is an entirely valid opinion. My point in reply to GP's reference to "crazy religious people" is that science can't speculate on any motivation behind observed phenomena, including whether motive exists at all or not. That's the reason I brought up my hypothetical Maker, to put forth a little mental experiment; is it conceivable that It may have made the rules so that It can tamper with them? Yes, it is. Not very logical, and it doesn't pass Occam's razor, but why would our hypothetical entity —capable of creating the rules— be bound by those rules? Please note that here I'm not advocating for nor against, merely presenting scenarios.

      You are falling for the same trap as GP: anthropomorphizing the universe, in your case by ascribing to it the characteristic of "uncaring". I was trying to point out that science can explain how the universe "is", but not "why". "Why" demands intention otherwise it would be randomness, and devoid of intentionality asking "why" is meaningless. But intentionality (even of things human) is a very tricky business for science to disprove, and by my logic, not being able to explain intentions precludes you to give value judgments over the moral characteristics of the universe. Or in English: science can tell you the mechanics of some phenomenon but it is neutral to it and won't help you decide if it is "good", "bad" or "uncaring". That's the realm of Ethics, a discipline of Philosophy.

      I can be wrong, but it's my understanding that generally we observe Phenomenon A1, and either consciously or as a result of a prehistoric grunt, then we give it a name whereby Phenomenon A1 then becomes "rain". We shape the words around the world, because the world is out there a-priori. Which is another statement that has been hotly debated, but whether that world is a shadow of Platonic Ideas, an objective reality or other, we still perceive something on average, and we develop our language around that perception. It may seem otherwise because of the way language is taught to us ("Look! this is An Apple"), but you were referring to the actual existence of things ("Oh, I have observed that Phenomenon A1 takes place.
