Sometimes I wonder if it's simply trolling. Like this exchange of comments on the second page where one poster made a long thoughtful post citing the example of mathematics, but also saying:
There are many examples I could offer, but the arguments are complex and I fear they might lead to off topic detours, so instead of discussing Leibniz, I will use a simple example that anyone can understand and agree with: mathematics... I could give you other examples but I trust I have made my point.
Cofty didn't respond to any of the part of the post discussing mathematics, instead simply making the comment:
I get the impression that the only example of things that cannot be known through empirical scientific evidence is pure mathematics.
Is that correct?
That's more than simply being obtuse, is it not? That's got to be deliberate trolling.
