Immanuel Can wrote:That would be magic, not science.
If things just happen without a cause, then they just happen without a cause. That would be a brute fact about what the world is like. Just because it isn't conventionally accepted as an assumption in the sciences, that doesn't have any impact on whether it's what the world is like. It's not as if the world says, "Oh, well, humans' model of the world doesn't include such and such, so I'd better not do that. I need to follow their scientific model."
We can't scientifically show that all events must have a cause. We can't even scientifically show that any event really did have a cause. (Read your Hume after all.) What we show is that y had cause x per how we think about what happened.
And then you'd have to explain why today things don't just keep happening without any cause
They might. We don't know that they do not. I had said this already. We don't really have any idea whether things happen per causes or not. What we do is talk about how we think about them, given the assumptions we make, given our perspectives, etc.
or other words, why science works now, if the start of all things is just magic.
I don't know how you're defining "magic" contra science really. You'd need to make that explicit. You're stating that as if there's a well-acepted demarcation criterion, by the way, as if there isn't still a demarcation criterion problem in phil of science.
Because "time" is a property of the material universe, and the material universe had an origin (the Big Bang).This has been confirmed by the "red shift" observations, among other things, and isn't any longer in dispute.
. . . which has
absolutely nothing to do with whether time is a
contingent or
necessary property. I was asking how we'd know that it's a contingent property.
Also, aside from that, one thing that definitely would be a hallmark of science--although it's not sufficient to be all there is to a demarcation criterion, is that science is
always revisable. So there isn't anything beyond dispute.
Untrue. See above.
True. See above.
And if so, then whether you regress by science or by faith, you're going to end up with having to attribute the origin or the universe to a "causeless Cause" of some kind -- either an impersonal one or a Personal One.
No, you can't get to a "causeless cause" if you need a cause for everything. You have to not need a cause for everything, or you're stuck with going back in time infinitely. Those are the only coherent choices.
Science has no explanations of things coming into existence "spontaneously" out of a genuine "nothing."
The world in no way depends on received views in the sciences.
By the way, I don't know if you're thinking I might be religious or something. I'm not at all. I'm an atheist.
I also reject the religion of scientism just as much as I reject religions like Christianity.
