Hi, AI. Good post. I'm going to continue to argue against it though.
My point earlier was that 'evidence-based' inferences still require faith in the evidence, in our perception of it, and in whatever inferences we draw from it.
Not only do scientists have great confidence in certain evidence, but so much so that we speak of the "laws of nature". This of course applies to observations which are universally repeatable. Thus I can say "I know for sure that ice begins to melt at just above zero degrees Celsius in an ambient of 1 atm of pressure" or "the acceleration at sea level due to gravity is about 9.8 m/s²".
There certainly are a huge number of cases for which this certainty does not apply. But to even use the word "faith" in a statement about scientific observation implies, in the context of scientific discussion about the particular topic at hand, that there is some doubt about the data (usu. the method of data collection), either because it has not been subjected to rigorous quality control procedures, or some anomaly exists which makes any conclusion premature, and so forth.
Of course it's hard to generalize here since the field of science is no very broad.
Remember Kittamaru's insistence that "the senses are flawed".
I am very glad to remain in possession of those senses which still work in me, so I will have to take issue with Kitt. The senses are evolved from the oldest of organisms, which needed access to energy sources to survive, and thereby evolved sense organs (or organelles) with which to locate those energy sources. It is that success in finding energy which (among a host of other things) led to the evolution of human senses. But I can name countless machines which sense things as well or better then than any organism can.
Of course, the statement is rather ambiguous. How flawed is human vision? I would say it's just about good enough to discern an attacking predator from, say, our next meal. Otherwise we would have some other kind of visual apparatus working inside of us.
Hence the argument was made that eye-witness testimony of unwelcome things can be dismissed simply because it's eye-witness testimony.
As you know, eye-witness testimony is often admissible evidence in courts of law. And as we know, a great many injustices can result from allowing witnesses to control the outcome of a court decision. But I think once we gravitate toward "unwelcome things" we are drifting into something a little more like emotion than reason. It implies that the search for truth is somehow being manipulated. In short, there is no room for eye-witness accounts in science, other than as initial reports which need to be substantiated. Galileo was the first known eye-witness to the orbit of luminous objects around Jupiter. And indeed, he was correct in inferring that Jupiter had its own moons (confirming the Copernican view of a heliocentric "universe"). But we can only say this with confidence today because it has been universally and repeatably witnessed by every person who took the time to research the question himself. In fact, Galileo wrote later that he was frustrated by the refusal of church investigators to even take the time to look through a telescope themselves (every night over a period of several weeks). And of course he was under house arrest for the rest of his life simply for publishing what he witnessed.
But the whole idea that 'evidence-based inferences' are even possible requires faith that despite the possibility of error and illusion, the senses still remain capable of providing us with true and reliable information.
I think the standard is different. When every person in the room sees a blinding flash of light and a hears a clap of thunder, there will normally be no question as to the cause. But in a war zone, hunkered down in a bunker, they will probably check the weather station to try to discern the true cause. It's this ability to combine facts and evidence into properly formulated logic that gives us that sense of reliability you speak of. But in every case, it's the universality of repeatable results which casts certain conclusions in concrete. Having seen the pictures taken by probes that visited Jupiter, you yourself would probably not doubt that Galileo was correct. I am quite certain you agree with Copernicus.
My view is that the same basic epistemic process is occurring in religion as in the rest of life. Atheists will try to argue that the objects of religious faith are far less credible than the objects of scientific faith, and that there's far less justification for having faith in them. But my opinion is that in both the religious and secular cases, what we see is commitment to propositions whose justification is imperfect.
Does that mean you reject Galileo or Copernicus or any of a thousand matters of "settled science"? Atheists. I think, will argue that the religious objects simply do not exist, or rather that objects purportedly having magical qualities are simply artifacts of folklore. And they will do so with certainty when they have the requisite knowledge, since, once we establish that there are "laws of nature", we establish that they can not be repealed by anything other than newer, better evidence.
It seems to me that logic is based at least partially upon intuition. We just kind of intuit the principles of logical inference and the logical necessity that supposedly adheres in them. And we just kind of assume that there's something intrinsic to physical reality that makes it conform, always and without any exceptions, to our logical intuitions.
Again, this is an inherited faculty. We step out of the way of a speeding train for the same reason a rabbit heads for its hole in the presence of danger. Our actual survival, and that of countless ancestral organisms, is "living proof" that the sense faculties are not as flawed as Kitt mentioned. In fact, I would assert that the senses are "just good enough" to correctly appraise the world each organism lives in. And I base that on other laws I know of, which assure that (usually) a minimum of resources will be expended in the evolution of a trait that improves the survivability of a creature withing its niche.
I agree that reality does seem to behave that way and that's probably why human psychology evolved these particular intuitions. But while that might explain, it doesn't fully justify the belief that our intuitions must hold true universally, everywhere and always.
I don't think anyone is claiming that; in fact that is why we dismiss lunatics and magic (to include religious metaphysics) from the science rooms. However, when we notice certain observations do in fact hold true universally, everywhere and always, then we say we have "settled science", in other words, we have now concluded that a natural law has been observed in action.
How can science proceed without faith in inductive reasoning?
In fact science can not proceed without doubt. We must test every allegation before making findings of fact. Inductive reasoning has some limited value among all of the tools in our box, but moreso in pursuing rigorous theoretical predictions than in the applied sciences. I think that's where we find the huge reliance on universally repeatable results.
That particular item of faith seems to be built solidly into what science is.
"Universal repeatability", yes, is built solidly into the confirmation of evidence and the determination of natural laws. But not "faith" itself, at least not until we agree that every observation is suspect and subject to some kind of aberration depending on the observer. But when or where does that apply? Almost never in the lab, at least not when dealing with a system that employs quality control. (Of course the QC process may be faulty, but that's another issue.)
