Here is a trick that I stole from some of the atheists.
They are so proud when they explain that for all the versions of what reality really is as different versions of God, they believe in one less than believers in God. That is correct, but most of them also believe in a version of what reality really is. The joke is as a skeptic, I believe in one less than them, because I don't know, but they do.
So here it is for knowledge:
There are many different versions of with knowledge I know what reality really is and that is not just some God believers, that do that.
So I do one version less than all those with knowledge, because they all individually know which one is the correct one, but I don't know that, so I do one less as for knowing, which one is correct.
I mean, they, the scientific skeptics, taught me well, as to be skeptical, to the point that I figure out that none of us are special, in that I know as correct where everybody else knows incorrectly.
But I am not supposed to say that aloud, because they as a social we for what ever version of Knowledge hold authority over what reality really is and that can't be doubted. BTW that is the joke of the 2 main versions of philosophy. The universal positive answer with rationality versus the limit of even that.
So these debates of what reality really is, is great training in learning the limits of cognition, but the problem is that some people treat as really real for the world as such.
