Well, if you are "not so sure" that you are being impossible, then it follows that you are not certain you are not being impossible, and hence that you
don't know you are not being impossible. So, why should I take any of what you have to say seriously. Since no belief is absolutely certain, for reasons I have pointed out previously, it follows from your criterion of knowledge that you don't know a damn thing. So, I guess I should stop wasting my time responding to your posts, right? I mean, if you don't know anything at all, then what's the point?
The three arguments I have given in my previous post are pretty decisive. You cannot be absolutely certain that you are not dreaming, or that you are not in the Matrix, or that you have two hands, or that your phone number hasn't just inexplicably changed. So, I guess that means if somebody asks you if you know your phone number, you'd have to say "no, I don't".
I am not absolutely certain that my ethical beliefs are true. Then again, I am not absolutely certain that my belief that 2+2=4 is true. I could be irremediably conceptually confused, or cognitively insane, and thus it could be the case that although it appears to me that 2+2=4 is necessarily true (it strikes me as clear and distinct, in the Cartesian sense), I actually radically misunderstand the concept '2' or the concept '+'. Of course, I take the odds of this sort of radical error to be vanishingly small, and my belief that 2+2=4 to be justified. I feel the same way about my ethical beliefs. Although I am not certain about them, I am as confident in most of them as I am in simple a priori truths of logic and mathematics. Since this is as good a level of justification as any of us can hope for, I am perfectly content with it.
I am not sure why you think that my ethical beliefs are verified by statistics. That is just a mistake on your part.
If you would like to discuss some other theory of knowledge, then please present one. So far, you've only given me one necessary condition for knowledge, and I've explained to you why it leads to global skepticism of a self-refuting sort. Your theory of knowledge (to the extent it is a theory, rather than merely a claim on your part) is flat-out stupid for the reasons presented above.
Atheism and/or theism has absolutely nothing to do with any of this, and neither does faith. Nothing I have said so far presupposes anything about atheism or theism. Nothing I have said so far relies upon faith or invokes faith in any way. Your claims about atheism and faith in here are completely irrelevant to epistemology generally and to this discussion in particular.
