No, I mean knowledge as in grounds for belief. Or evidence for belief, whatever you want to call it.
Well, there’s a difference between
grounds for belief and
evidence supporting a truth claim. There are plenty of grounds for religious belief - it provides succour, it provides community, it documents a particular standard for morality. None of those things is the exclusive domain of religion, of course, but for those who happen to identify closely with them in that context, they provide
grounds for belief. They don’t constitute
evidence that the truth claims of that religion are true. And at this point, let’s remind ourselves of the title of this thread.
What I mean is that those that subscribe to scientism argue that unless your evidence comes from the scientific method, then you have no grounds for belief. For example, if I were to provide a philosophical proof for God’s existence, you would balk, since a philosophical proof isn’t the scientific method, and thus can’t be considered grounds for belief. This seems like what you were implying when you said " Well, it would be, given that philosophy doesn’t ever produce actual evidence." My proof is to show that this line of thinking begs the question, and I think it still does.
Again, you’re misrepresenting “scientism.” Or at least, using the word in its pejorative sense, and it’s that inaccuracy that is causing a problem.
“Scientism,” as in “the belief that the scientific method is the only known way of identifying objective truths about the world,” does not state that there are no other
grounds for belief. It merely acknowledges the fact that without robust evidence to explain a particular phenomenon, the conclusions drawn about it are not credible enough to be established as fact.
And you’re right, a philosophical “proof” for the existence of God is not sufficient, for the simple fact that philosophy is by nature subjective. That doesn’t mean a philosophical proof can’t be considered
grounds for belief, but it isn’t enough to demonstrate that the truth claim (the existence of God) is correct.
To take a facile example - once, thunder and lightning were taken as “grounds” to believe that the gods were angry. It was never “evidence,” but it satisfied the needs of the people who were predisposed to believe in gods.
So I can happily concede that, say, Aquinas’ five ways are “grounds” for your belief; they do not even remotely constitute evidence for God’s existence.
While you conflate “grounds” and “evidence,” this conversation will go nowhere.
