That's the big problem that comes with philosophical materialism. Exactly that kind of cognitive blindness. It's why philosophers rejected it as soon as it was proposed. Unfortunately, it's foolishness lingers.
So you're choosing not to explain what you're talking about.
Your choice.
This post is directed at Penguin, but I felt I needed to add PureX's quote for context.
Penguin, you could go on and on about the merits of empiricism and I would agree with you on every point. I bet there isn't one thing about empiricism that we disagree upon. So you could list one-by-one the things that make empiricism reliable and how it always supplies certainty, and I'd keep agreeing and agreeing.
You are correct. Empiricism is great. It's dependable. If empiricism determines that something is true, then it's probably true. Let's start the conversation by saying that science gives us the most reliable information we have. Period. There's no disputing that.
And let's also say that many disciplines and ways of drawing conclusions that are pseudo-scientific can be rejected on that basis.
All, I'm saying is: once we've gathered all our evidence... once we've drawn the proper logical conclusions that follow from that evidence... once we've ruled out the things that are obviously false and said most of the information that science gives us is very much more reliable than any contrary information is... once we've done ALL of that. We can pause. And we can soak up as much of that correct and reliable empirical information that we can. And that's what we should do.
But once we've done that. We still might be left with questions. Questions about ethics. Questions about aesthetics. Questions about what purpose our life should serve. These don't need to involve any sort of religious BS (and in my case, they don't). But (in my case) science hasn't answered these questions to my satisfaction. A proponent of scientism would say: "Hey vulcan, don't bother trying to use your brain and/or logic to answer any of those questions. The only answers that count are empirically verifiable ones. No need to take any other approach."
But there's plenty of reasons to think that (carefully) thinking about a subject --such as literature-- can produce insights and knowledge. I could study Leo Tolstoy and come away with a bit of truth. Not a kind of reliable truth that I can tell others to believe. But also not some "personal truth" that only can be believed from a certain perspective. Literature and philosophy can hold aloft many universal truths that are simply not in the purview of science.
Does that make those disciplines better than science at getting to the truth? No. You and I probably agree that science is the best truth-producing discipline we got. But knowledge doesn't end where scientific discoveries end. We can get to the truth other ways. Science isn't the ONLY way. It's simply the most dependable and accurate way... to get to the truth.
Someone who argues in favor of scientism says more than "it's the best and most reliable way to the truth." They go one step farther. They say it's the only way. And THAT (and only that) is why I reject scientism.
