Title: Pragmatism


1
Pragmatism
  • developed in the U.S.
  • after the Civil War (ca. 1865)
  • no longer content merely to reflect European
    philosophy
  • a new approach for a new and vigorous young
    nation
  • 3 key thinkers
  • William James
  • Charles Sanders Peirce
  • John Dewey

2
William James (1842-1910)
  • trained first as a medical
  • doctor, then a psychologist
  • finally became a philosopher
  • and the chief advocate of
  • Pragmatism
  • James shared the American distrust of purely
    theoretical or intellectual activity, and asked

What is the point of theorizing? What difference
does it make? Why is it important to bother with
the mind games of theorists?
3
What is Pragmatism?
  • It is
  • a method for evaluating intellectual problems,
    and
  • a theory about the kinds of knowledge we are
    capable of acquiring.
  • The Starting Point
  • Before determining if any given philosophical
  • claim is true, James thought it first
    necessary
  • to determine the cash-value of the claim.

4
Cash-Value
  • The cash-value of our ideas is to be found
    in the use to which they can be put.
  • With regard to any theory, we can ask what
    difference it would make if I believed it, and
    what consequences it would have for my behaviour
  • If it would not make the slightest difference
    whether I believed a theory to be true, and it
    had no effect on my actions at all, then the
    theorys cash-value would be zero the theory
    is useless

5
  • Theories ought to be judged, then, in terms of
    their success at helping us solve problems --
    they are the instruments we use.
  • Suppose you get lost in the woods, and use your
    knowledge of the suns position, the direction
    youve been going, previous info. about the
    terrain, etc., to develop a theory about how to
    find yourself again.
  • the cash-value of your theory will be judged
    according to your success in avoiding becoming a
    midnite snack for Smokey the Bear

6
  • By contrast, many classical philosophical
    theories have little or no cash-value.
  • What difference does it make if you believe (or
    disbelieve) that the universe is really only one
    vast mind?
  • It would change none of the daily problems you
    face, and give you no clues about how to resolve
    them.
  • At best, such a metaphysical belief might make
    you a little bit happier (or sadder, if you
    disbelieved) beyond that, it has almost no
    cash-value.

7
  • Reflections like these led James to a simple
    conclusion
  • A theory is true if it works.
  • Traditional (rationalist) philosophers like
    Plato held that the truth of ideas is not
    dependent on human experience -- an idea is true
    or false whether anyone knows it or not.
  • James argued that the only meaningful way to
    gauge the truth of an idea is to see whether it
    works.
  • claims about absolute, objective truth are
    meaningless, since they can never be proven by
    experience

8
Pragmatic Truth
  • For a pragmatist, then, truth isnt something
  • a idea has -- it is something that happens
  • to an idea.
  • Before you discover whether an idea, theory, or
    belief works, it is neither true nor false.
  • As you test out the theory or idea, it becomes
    true or false, or more true or less true.
  • In other words, truth is not something static
    and unchangeable -- it grows and develops with
    time.

9
  • This view of truth fits quite well with modern
    science, which progresses by means of
    experimental trial error through a succession
    of increasingly accurate theories.
  • Newton, for example, worked out the laws of
    motion, and for centuries his theories were
    considered true because they worked.
  • When Einstein showed that the classical laws of
    physics didnt quite work in certain situations
    (esp. as one approaches the speed of light), our
    understanding of the truth about motion changed.

10
Pragmatism and Ethics
  • For the pragmatist there is no fixed world
  • to be revealed by experience there is only a
  • continuous quest to find workable solutions to
  • lifes problems.
  • The way to discover what is morally right or
    wrong is the same as when seeking truth a good
    action is one that works to solve a given
    problem.
  • e.g. Is the right way to solve ones money
    problems to rob a bank?

11
  • Presumably, one pragmatist would consider all
    the possible unsatisfactory consequences for
    oneself and others (i.e. imprisonment) and
    conclude that bank robbery is the wrong
    solution.
  • On the other hand, another might just as readily
    conclude the solution is right -- IF they get
    away with the crime.
  • Clearly, then, pragmatism offers no absolute
  • moral principles -- the good is what
  • works, and judging this involves a purely
  • subjective evaluation.

12
Criticisms
  • At what point can you tell whether an idea
  • has worked?
  • Some pragmatists respond that you must look to
    the long-term consequences, but
  • those consequences may go on forever
  • the idea might work only sometimes
  • We need some criteria, a moral framework but
    this is just what pragmatism tells us we cant
    have (because its meaningless) .
  • There is a danger of falling into a morality
    based on personal preference (Well, it works for
    me!).
