Re: What evidence would you accept for human evolution?

If the Sun itself did not move, it might have been the best hypothesis. As things stand, it was only the first step in better cosmology. But there was more to learn than Copernicus knew. His was a step, but not the last.Will Bouwman wrote: ↑Thu Mar 20, 2025 8:37 amDo you not think that, in its time, Copernicus's heliocentric model was the best?Immanuel Can wrote: ↑Wed Mar 19, 2025 3:04 pmIt would only be a better one than the geocentric theory, not the best hypothesis.

By which measure the heliocentric model of Copernicus is a good hypothesis, because it accounts for the data better than the geocentric model it replaced.
If it were "certain," it would not have to be "indicative." The truth is, as Idealists have long pointed out, we cannot be absolutely certain that reality itself, and all of its data, actually exists. We can be probabilistically convinced of it, and reasonably so...but not absolutely certain. It is possible, after all, that we are "a brain in a vat."The "indicative evidence" is what we know with absolute certainty.Immanuel Can wrote: ↑Wed Mar 19, 2025 3:04 pmWe cannot. That is why all human creatures live by faith, whether they know it or not. We cannot avoid the expedient of putting trust in things for which we have only indicative evidence, not absolute certainty.Will Bouwman wrote: ↑Wed Mar 19, 2025 12:01 amHow then could we ever know that there isn't some phenomenon that we are not currently aware of that our best hypothesis cannot account for?
You're still too confident, I would say. Neither the secular scientist nor the theologian has "absolute certainty" of any kind...not even about the existence of physical reality itself. It is always possible, in extremis, that the world itself is an illusion. And while you and I would, in faith, reject that as highly improbable, it is only by dint of that final commitment of faith that we can do so. It is not certainty.Similarly, what anyone who has indicative evidence of God knows with absolute certainty is that they have indicative evidence; what they cannot be absolutely certain of, at least as long as they live, is why.
But we must not confuse epistemology (i.e. what we happen to know at a given moment) with ontological reality (i.e. what is really the case, when perhaps we don't yet know it). I have not even remotely suggested that we have the right hypothesis NOW, or have to. All I'm suggesting is the ontological side: there will always be a best possible hypothesis, whether or not anybody possesses it yet. There will be some postulate that accurately reflects what reality is, in a given case.Of course something is true, but it doesn't follow that any hypothesis we come up with will reflect that.Immanuel Can wrote: ↑Wed Mar 19, 2025 3:04 pmStill, always, something will end up being true. So some hypothesis will be the right one.
But just as 100% of the people in the world once believe it was flat, that did not mean there was not a better hypothesis -- namely, that it is round -- and an even better one -- that it's only roughly so, not exactly so. And the third turns out to be the truth -- assuming, of course, that it all doesn't turn out to be an illusion. Human hypotheses are not the definer or creator or shaper of reality. They're only human attempts to come to grips with the reality that already pre-exists our attempts.
