What do we know "for sure"? If we do not even know "anything for sure" can we be certain of even that? Might we stumble upon the truth and not even know it? For can we be certain that "nothing is certain"? Doesn't that scream CONTRADICTION!? So if we cannot be certain that "nothing is certain" does that PROVE there is "something that is certain"?
Is being certain that there is something that is certain results in TWO distinct certainties ; one is "being certain in and of itself" and the other one is what it is that we are "being certain of".. or is there only one certainty and that is of being certain of being certain ad infinitum?
What do we mean when we say "reality" or what is "real"? By real do we mean what is timeless and perfect and permanent or do we really mean what it the highest order "truth" of the way the omnium multiverse and all of existential and totality of "existence" "works" and its nature of "being" and all that? Even if we solve a Theory of Everything that would only explain everything that is of this "physical universe", what about "qualia"? Consciousness? And what would explain the existence of the fire in the equations, for why should THEY exists?
