One of the things I've been exploring over the past year and a
   half, is a serious look at the awkward zones; the paradoxes, the
   uncomfortable places where things can be simultaneously possible
   and impossible. I've been following a few rules that developed
   organically over that time and come to a few - very few -
   conclusions. a) The only always 100% honest answer one can give,
   when all is said and done is, "I don't know".* Everything that
   isn't "I don't know", is really "I believe/I don't believe." b)
   To understand paradoxes, dichotomies, etc, its important to look
   at where the very idea of paradoxes or dichotomies come from.*
   It has a history, a name, an origin.* Aristotle.*
   [1]http://en.wikipedia.org/wiki/Law_of_excluded_middle In this
   way of thinking, there can be no "third way"; no zone where two
   contradictory things can be simultaneously true; it must be one,
   or the other, but not both.* It has been very helpful, and
   continues to be helpful, but ultimately, I believe it will limit
   our progress as a species. c) To understand ideas, I looked into
   where the "idea" of idea comes from; that's Plato.* Perfected
   forms that have a timeless substance that goes beyond our plane
   of existence; and reflect a greater reality than we are capable
   of perceiving completely here.* it's very much a part of how we
   have been trained to think about the nature of things. But, in
   the end, it's the concept that comes from a real guy, who
   happened to influence Western Civilization in a huge way.** It
   is a belief that he is right; that there is mind vs body; ideas
   vs reality - that they are different and do not cross over. The
   parable of the shadows on the cave wall has proved to an EXTREME
   influence on our civilization. This doesn't mean that these
   things are wrong; but rather, that, with it, we are holding onto
   a set of assumptions about the way things are that may, perhaps,
   be culturally based and not necessarily absolutes.* Just
   absolutes in our cultural conceptualization of the Universe. d)
   Objectivism; that "only what is objective can be true" is the
   product of 19th century philosophy and has been very influential
   in modern ideas of "What is true". But it was not always so, and
   need not necessarily be so. The Philosophical system that
   governs this stuff is Epistemology; a product of the 19th
   century as well.* I'm not very good at philosophers and the
   like; I like going back to ancient times to find
   civilization-origins; I find the newer (19th century) stuff to
   hurt my brain - I was never good at it, but the concepts I
   understand more or less. the book from the future; if someone
   declares "this book is from the future", and they happen to be a
   respected scientist.* He comes up with a testing methodology
   that confirms it is from the future.* Other scientists confirm
   using their methodology that it is from the future.* Everybody
   believes it is from the future and no method is ever discovered
   to counteract that this book is, indeed, from the future. Then
   is it, from the future? There is no hoax.* it is believed by
   all. Yet, what makes it so? Where does the certainty come from?
   Certainty is a biochemical process in the brain; it comes from
   our emotional centers.* There's a whole psychology behind the
   nature of certainty.* It feeds into our belief system about what
   is true and what is false. But what if uncertainty was the norm,
   and our biological processes giving us a preference for certain
   as, let's say, a survival technique, is merely an artifact of
   our being human? All of course, of course, confirms your
   original point, which i believe to be true; that we are,
   ultimately, limited in our capabilities.* Still, I wonder how
   much of it are true limitations, and how many are imposed upon
   us by the time in history we happen to find ourselves in, and
   the societies we happened to grow up in that teach us that these
   assumptions are true?
