Good information can be expressed with it. It can even be
  accurate and precise. I've seen and produced good examples of
  it, even long before I knew it was called "post modern". I'm
  writing "terse" and short here because I'm pressed for time. But
  given the time to just write, I can weave together a tale and
  use all the synonyms in my mental databank and turn 2+2=4 into a
  marvelous tale of systems upon systems, histories swirling,
  morphing and changing through time, cognitive structures alluded
  to and diving into quantum mechanics and poetry and music....
  ... yet I can also do the same with 2+2=5. That's what's scary
  about post modernism. If you're not paying attention to what
  they're saying, it can slide right by. == At the same time, it's
  easy to hide bullshit in every discipline. Just go through some
  of the open source theoretical physics papers sometimes. There's
  BS there too. Math tricks used to create improbably conclusions.
  I've seen it with logic. Nice logical structure but with bad
  beginnings lead to bad endings with perfect middles. Thought
  experiments are the worst offenders in this regard because we
  barely question their validity. We forget easily that: they're
  fiction. == The interesting thing is: Each of them DOES have
  their own logic. It's _possible_ in some way to justify any
  paper as correct. You can turn a logical inconsistency into an
  allegory or a metaphor, etc. That's what makes it easy to
  justify anything in _some way_ and also tricky to discern
  truth-values sometimes. ==
