   I was trying to make sense of this paper by a
   Phyllis Chiasson which uses some of Peirce's
   ideas with some ideas by Dewey:

    The Peirciean notion under
    discussion is interesting:

    Hypothesis (or goal) acquisition takes
    place via a process called "abduction"
    (as opposed to deduction or induction)

    Induction is the formation of general
    principles from observation... one
    might just call those principles
    "hypotheses" that need to be tested.

    So where's the difference between
    induction and abduction?

           Possibly they're placing emphasis on the fact
           that you can really go in many directions here,
           and choosing a particular hypothesis has a
           goal-directed quality about it.  What makes one
           hypothesis interesting compared to another?

                 But similarly, amidst the chaos of sensory
                 experience and instrumental data (if
                 there's really a distinction), why seize
                 on one set of generalizations, rather
                 than another?

                        In practice, I think we would
                        probably say something like "this
                        is where intuition comes in", but
                        that's another way of saying we
                        don't quite know what we're doing.



In reading this paper, I think I was being tripped
up by an odd usage of "ends" and "means" which
come from Dewey's "ends-means continuum", which is
not something I'm familiar with.

Working it out on my own:

I don't immediately see why you would propose
a "continuum", though clearly a sharp distinction
between "ends" and "means" doesn't really hold up.

My first impulse would be to say that really actions
just have effects in general, and it's a matter of
perspective to categorize some of those effects as
the ultimate "ends", or the intermediate "means".

Actions have effects, some of those we classify as
desired, some we classify as "side-effects".

   In general, any kind of
   utilitarian calculus is going
   to have to add up positive
   results and subtract off the
   price paid for undesireable.              Perhaps radically
                                             undesireable,
                                             repugnant means.
        Part of your end may
        be to achieve it via
        clean means.

      
  It's interesting to consider that     
  the stated goal of an action might     
  be only an excuse, perhaps an         
  unconscious excuse.  It's often       Jonathan Stockwell, in a lecture I
  noted that holding a tool             heard in the early 80s, commented on
  encourages the use of the tool--      the *lure* of playing spy... reading
                                        other men's mail, far from being
      This is another way in            something gentleman are reluctant to do
      which means blur into             is actually irresistable to nearly
      ends: One of your                 everyone given half an excuse.
      goals may be to use
      all available means.

        "I have access to
         a woodshop.  What
         can I do with that?"           Still the notion of a
                                        "continuum" seems peculiar.

                                        To me, that suggests
                                        and axis like this:

                                           ends        means
                                          <--------o------>

                                        Can you vary a parameter
                                        to gradually shift from
                                        an end to a means?

                                               I think it might be an abuse
                                               of the word, a presumption
                                               the either you have separate
                                               categories or a "continuum".

  The author of this paper seems to be
  asserting that both deduction and
  induction are ends-directed, and
  that abduction is means-directed.

    Myself, I tend to regard deduction as "top-down"
    and induction as "bottom-up", the author
    seems to take induction as another kind of "top-down",
    but regards abduction as an actual "bottom-up" process.

            According to the author,
            Peirce regarded induction
            as a kind of sorting out              No creation of new
            of experience into                    categories in a flash
            pre-existing categories.              of insight is allowed?



                                                         (Jan 12, 2014)
                        The Stanford Encyclopedia
                        of Philosopy makes this
                        all clearer:

                            ABDUCTED_LOGIC

                        Deduction is certain reasoning from given abstracts.

                        Induction is fuzzier, reasoning using only one given
                        abstraction, and an uncertain leap to an individual
                        case.

                        Abduction is fuzzier still, a guess at the existence
                        of an abstraction from a few individual cases.


                              So, if you want to use a top-down
                              axis, induction ends up in the middle.
