a concept of existence that is purely physical, and thereby elevating science to being the only possible valid methodology of determining reality and truth.
What we are saying is that empiricism - experience, such as observing or tasting - is the only reliable method available for determining what is true about the world. The word "science" connotes test tubes and professional journals. Most of what I know about how the world works comes from experiencing it, drawing inductions from that experience, and testing them to see if they accurately predict outcomes.
That is empiricism. You call it science so that you can demean empiricists, implying that they go to physics books for all information, when almost none that they use comes from such sources. This is why I have begun referring to empiricism as formal and informal science, the former being the white coat in a lab type of empiricism, and the latter referring to the activities of daily life that reveal truth about life in exactly that same way, just not wearing a white coat or being at a telescope.
So, you've begun with a straw man. Empiricism, not science, is the only known method for determining what is true about the world, and you have no rebuttal to that, just contradiction without a sound argument. You have claims that there are other methods to determining truth, but never have anything to show from these methods that deserves to be called more than unsupported opinion, much less truth.
And then there is the claim that empiricists place too much reliance on evidence, which is the theists way of saying that strict empiricists are missing out on something, but never describe what that is.
So no, you have made no argument that there is any other method of determining truth than empiricism, nor that using other methods produces a benefit or that avoiding them comes with a cost. So, this claim is really nothing more than theists objecting to their principle method for deciding about gods, unjustified belief, being rejected by empiricists as a means path to knowledge, and condemning them for it without any argument or evidence to support your position that strict empiricism is a defective epistemology.
Stop throwing "falsifiable" around like it's a 500 lb. manhole cover. Very few things in our experience of reality are "falsifiable". And even those that you think are, are only relatively so. Meaning that they are only true or false relative to the context/criteria being imposed.
It seems that you don't understand the term. Falsifiable doesn't refer to the truth or falsity of a statement, nor to demonstrating the truth or falsity of a statement. Some falsifiable statement are correct, some incorrect (the ones that have been falsified), and some as yet undetermined. These are also called scientific statements. Unfalsifiable statements are never true or false, just undecidable (not even wrong) and thus all permanently undetermined and undeterminable, and are not scientific.
And you're incorrect about very few ideas in our world being falsifiable. Suppose I told you that I was having guests over for dinner tonight. If that is untrue, can it be shown to be in principle? Is there a method for disproving that if it is incorrect? Of course. And if it is, the claim falsified. And no Bunsen burners or microscopes needed. Just the bare senses.
science is not the right tool for art, or values, it is also not the right tool to investigate questions of God.
I don't need a special tool to investigate art or values beyond my own faculties and experience. I know what I find artistically appealing empirically. I see a few drawings or hear a few songs, and know directly whether they are experienced as art or something less, and whether I enjoy it or not. It is on this basis that I expect to like classic rock songs, but not rap, and choose my radio station accordingly.
I've experienced them before, and noted my aesthetic responses then - when I felt pleasure listening and when I did not. Empiricism. I don't know what calculations are going on out of view in my neural circuits - how my brain decides what is pretty or funny or whatever - but that is the tool I am using, and it is reliable. I present potential art to the senses and note whether the experience is more euphoric or dysphoric, and make future decision based on that empiric knowledge.
Now try to fit a deity into that. What tool do you have to determine if there is a god, and if so, what that god like? None. Theists are just guessing. I'm sure that you don't like reading that, but can you rebut it with more than the wave of a hand or the repetition of points already rebutted but then not defended, just repeated? I don't think so.
So why is it then, so many atheists on these sites, and RF is hardly any exception to the rule, do you constantly hear "Where's your evidence", when someone is saying they believe in God. Aren't they trying to use science for something it is unqualified for, like judge art?
There you go equating seeking evidence with science. It's empiricism. And yes, that is the only method I would use to judge anything, including god claims. If you present no compelling evidence, I note that and reject your claim. When you tell me that you have other means of determining truth, but can't demonstrate those methods or that truth, I reject the claim EMPIRICALLY, which is what is being called scientism in this thread, and criticized as being small-mined without a speck of evidence or argument to support the idea that life should be approached any other way.
