It's very good, although my quibbles are more semantic than
   anything, for while I find statistical models useful for certain
   things, a statistical or probability basis for everything isn't
   something that resonates with me.

   It's a useful abstraction for certain purposes, but even the
   level of 'benefit' all has a level of Adam Smith economic
   "Rational Man" quality to it, embedded within the later
   developments of evolutionary theory and strengthening of the
   force of statistical modelling as-ultimate-basis in the early
   part of the 20th century.

   It's not a bad model; not at all. But what it reduces to
   ultimately, I don't think is reflective of reality.

   But its not bad though.
