The  Epistemic  Paradigm                   91

        The  paradigm  considered  in  this  book  is  based  on  considerations  that  most
        philosophers  of science will find  acceptable.  Along with the dominant  tradition
        (e.g.,  Goldman,  1986),  we  regard it  as an evaluative  or  normative  paradigm,
        not  a purely  descriptive  one.  This is an epistemic  geostatistics  paradigm  which
        distinguishes  between  three  main  stages of  knowledge acquisition,  interpreta-
        tion,  and  processing as  follows:
            1. The prior  stage.  Spatiotemporal  analysis and mapping does not work in
        an  intellectual  vacuum.  Instead it  always starts with a basic set of  assumptions
        and  the  general knowledge  base  (7.
            2.  The  meta-prior  stage.  The  specificatory  knowledge  base  S  is consid-
        ered,  including  hard and soft  data.
            3.  The  integration  or  posterior  stage.  Information  from  (1.)  and  (2.)
        is  processed by  means of  logical  rules to  produce the  required  spatiotemporal
        map.
            Each  one of  the  above  stages will  be discussed in  considerable  detail  in
        the  following chapters.  The  epistemic  paradigm  includes elements from  both
        the  empiricist  and the  rationalist  traditions  (just  as scientific  reasoning com-
        bines empiricist  and  rationalist  approaches in  an inseparable method).  Within
        the  context  of  this  paradigm,  knowledge  comes  from  a synthesis of  concepts
        and  experience.  The  distinction  between  the  prior  and  meta-prior  stages is
        not  meant  so  much  in  a temporal  sense.  Rather the  real  meaning is that  the
        boundary line  between the  prior  and meta-prior  stages of the  mapping paradigm
        coincides with the  boundary  line  between general and specificatory  knowledge.
        However, while  the  distinction  between general and specificatory  knowledge is
        a  matter  of  logic, the  distinction  between the  prior  and meta-prior  stages is an
        epistemic  issue.  At  the  prior  stage, we process knowledge that  has been char-
        acterized  as general  on  the  basis  of  some logical  arguments  (Chapter  3,  "The
        General  Knowledge  Base,"  p.  73)  and  at  the  meta-prior  stage we  incorporate
        knowledge which—again on the  basis of  logical arguments—is considered spec-
        ificatory  (Chapter  3,  "The  Specificatory Knowledge  Base,"  p. 82).  The  use of
        the  terms  prior  and  meta-prior  is natural,  in this  connection.  Prior  knowledge
        comes epistemically—though  not  necessarily genetically—before observational
        experience.  Meta-prior  knowledge  is  born  pragmatically  from  experience and
        may change with use.




        COMMENT 4.2 : I n th e view   o f many   researchers,   Socrates   wa s th e firs t



        to clearly  point  out  the  distinction between  the prior and  meta-prior stages

         ('i.e., th e distinction between what  one knows  before   experience   with  the spe-



        cific situation  and  what  one  learns from the   case-specific   data).   Indeed,   sev-

        eral references   t o this distinction can be foundi n Plato's famous Dialogues








        (von Foerster,   1962;   Vlastos,  1971).   I n  hi s discussion  with Menon,  e.g.,
        Socrates makes the point that  education  is   in  many   cases  not  a   transfer  of

        knowledge from   teacher   to   student,   but   an   awakening   of   the   awareness   of


        knowledge already   possessed   by   the  student.  Without  this prior knowledge,



        Socrates argues,   experience   cannot  be gathered (at   the   meta-prior  stage).
