    niet teveel overneemt.

.Begin
  • Anekdote Polanyi vs. Bukharin.
  • the scientific outlook appeared to have
    produced a mechanical conception of man and
    history in which there was no place for science
    itself.

5
  • Obvious ideas which are universally credible are
    not always what they seem to be.
  • Shock omdat sommige mensen zijn werk verkeerd
    interpreteren.

. drie conclusies
  • 1. The program could grow into a nearly
    completely automatic form of psychotherapy.
  • - Helemaal niet de bedoeling dat dit zou gebeuren
    want menselijk contact juist heel belangrijk.
  • What is it about the computer that has brought
    the view of man as a machine to a new level of
    plausibility?

  • 2. Gebruikers heel snel emotioneel gehecht aan de
    computer/programma.
  • - Nooit gedacht dat relatie tussen computer en
    mens zo sterk zou kunnen zijn.

  • 3. It spread the believe that it demonstrated a
    general solution to the problem of computer
    understanding of natural language.
  • Mensen begrijpen computers vaak niet maar toch
    een blind vertrouwen. Dit komt door het idee dat
    het mogelijk is dat ze zelf denken.

11
.debat
  • Computers can, should and will do everything vs.
    Limits to what computers ought to be put to do.
  • The question is whether or not every aspect of
    human thought is reducible to a logical
    formalism, or, to put it into modern idiom,
    whether or not human thought is entirely
    computable.

12
.losse gedachtes
  • Rationality-is-logicality equation bestaan er
    nog human values? Skinner nee
  • Scientific statements can never be certain they
    can be only more or less credible.
