+[1]KENNETH UDUT: Intersubjectivity is a word I don't see nearly
  enough and you're right; in the actual practice of science, the
  lines that seem so nice and clear to students are, as always and
  thankfully so, blurred by good ol' reality, at least from what I
  can see. And I feel this makes trying to talk to people who are
  embedded and invested in a "scientific" outlook particularly
  frustrating at times because they tend to take for granted their
  philosophical position about what it is they are actually doing.
  I've had several debates with a few people that were essentially
  futile simply because they were so entrenched in the idea that
  they are establishing "truth" about an "objective" reality that
  they can not even begin to see the error they are making; that
  is, the idea of a shared intersubjectivity is like Kryptonite to
  their Superman science: it weakens them to the point of becoming
  entirely irrational and unreasonable. And so it goes. I have,
  alas, been hanging around several Philosophy forums over the
  past six months, conquering once and for all, a lifetime
  distaste for that method of discourse... at least.. as it
  manifests itself on the Internet. Well, there's this joke about
  Wittgenstein, see. It goes like this: Wittgenstein was on his
  way to give a talk at a "professional philosophy conference." He
  comes to the place where the conference is being held and walks
  up to the registration desk to claim his spot and register his
  attendance. Now, Wittgenstein, of course, is looking his regular
  self, which is to say shabby, disheveled, bag bulging with
  books, and the concierge--not familiar with any of the attending
  philosophers--looks Wittgenstein up and down and says, "I think
  you've made a mistake: I am afraid you've stumbled on a
  conference of philosophers." And Wittgenstein says, "So am I, so
  am I." Philosophy on the internet is frequently like many things
  on the internet: a sort of pale specter of the real thing.
  Further, everyone can think they are a "philosopher" simply
  because they can also opine on some such matter or another, and
  the internet seem rife with people more than willing to not only
  offer their opinions on such and such, but to also resolutely
  hold to that opinion to the point of becoming entirely
  irrational and unreasonable. And so it goes. And
  sometimes--perhaps even often--philosophy as done in real life,
  as done "professionally," isn't much different, heh. Ayn Rand
  anyone? Lol, it is so funny you should insert this into your
  response. I've had a conversation or two with some
  ("scientifically" minded) people who, if not Rand followers,
  will at least assume the metaphysical tenets of "Objectivism"
  and act as if these somehow justify every single dogmatic thing
  they say about an "objective reality." What's worse is they
  often fail to see how "Objectivism" is self-defeating. I mean,
  sure, we can assume there is some "external" reality which we
  interact with via our sensory perceptions, but the very fact
  that we must necessarily interpret those sensory perceptions as
  a human being implies at best an intersubjective network of
  reporting on those experiences and perceptions: what is a
  "reality" separate from our human based processing of our
  sensory perceptions? Like there is a coherent answer to this
  question! Fallacy? Oh if I hear that word one more time... Lol
  again! If we explore the list of "fallacies"--both formal and
  informal--we end up, I feel, at the end of Wittgenstein's (not
  to overly favour his work or him in particular, mind) Tractatus:
  What we cannot speak about we must pass over in silence. And
  yet, we'll talk and talk and talk all the same, heh. We're all
  just people doing the best we can with whatever knowledge we
  have at hand at the time in whatever roles we may be playing at
  the time. Yes. There is a practical sort of pragmatism to our
  knowledge, but this does not mean such knowledge is "truth": our
  knowledge is at best "functional," which is also to say the
  models we frame our knowledge in have some degree of workability
  (as I like to call it), yet this does not necessarily require
  that they are accurate, complete, or even "true." It simply
  means that they work to some degree, and to what "degree" we
  simply can not know as that would imply that we have a complete
  and accurate account of reality to compare them to! I was
  excessively harsh regarding perceptions of the Subject because I
  find myself defending its ... well.. ultimate truthfulness:* not
  as "absolute " or "ideal form"* - but as a series of on-going
  negotiations in shared human attempts towards... Ah yes, I see
  where you are coming from. I tend to feel that people can simply
  be too frightened or too lazy--or whatever else--to accept the
  responsibility that is entailed by existing as a First Person
  Experiencing Being In The World. We want assurances, we want
  stories, we want ways to lull our sense of "existential dread"
  qua our utter singularity of being to sleep. We do not want to
  feel alone in the world and we often seem to do whatever we can
  to avoid being alone with ourselves. I don't know what it is we
  are "working towards," if anything. I tend towards rejecting the
  idea that there is any sort of "absolute" teleology to being;
  rather, we go back to what is pragmatic: what makes our life
  worth living, or, what is our answer to Camus' "only one really
  serious philosophical problem"?
