Fresco, I am glad you are not ignoring me.
I'm not even trying to “define” anything here, I’m just participating in a discussion.
Theist don’t know there is a GOD…some of them insist they know, but that does not mean they know…it just means they say they know or they insist they know.
Some atheists say they know there are no gods…but that does not mean they know there are not gods.
The reality is that there are gods or there are no gods (actually, it may be something different then even those two choices that simply cannot be understood by us)…and that reality, it seems to me, is not dependent upon how any individual feels about reality…unless, of course, the reality is that “reality” is what someone feels about it.
Wittgenstein could stake his political career on being Napoleon reincarnate, but that would not make him Napoleon reincarnate…so the fact that he has staked his career on what you mentioned does not actually come into play.
Mostly, I have been talking about what is “at least possible”…and it is at least possible that no philosopher who has ever considered this issue has ever come close to resolving it.
