What is it you have trouble understanding about '100% certainty thought exists' saying nothing whatsoever about 'Darat thoughts' or 'hammegk thoughts' existing at 100% certainty? I've agreed time and again the choice to have faith *i* think (and by corollary, *you* think) is not a 100% certainty.Have to disagree - I don't think we can be certain of anything - every one of my thoughts may be completely wrong (including that I think I experience thoughts), I just don't know.
