What is the "logic" in Buddhist logic?(3)

分享到:

     relationship  between  the  thesis  (pak.sa) and the
     justification  (hetu) is  always  expressed  in  the
     Sanskrit  ablative  case and that this  relationship
     cannot be represented  or translated  as the English
     "therefore"  (or  ergo).  Its  best  translation  is
     "because."   Thus,  for   the  incompatibilist,  the
     primary objection  to identifying  the Nyaaya scheme
     as a deductive  inference  is the  familiar  one  of
     ordinary   language  philosophers   who  resist  the
     translation  of expressions as `q because p' into `p
     ) q' on the  grounds  that  the causal or explanatory
     meaning   of   "because"   is   lost   in   the
     truth-functional conditional.

      This   objection   has  force,  but   one   must
     distinguish   between   the   assertion   that
     truth-functional connectives preserve or capture the
     meaning   of  `q  because  p'  and  the  claim  that
     truth-functional   connectives   can   represent   a
     deductive relationship  between propositions  within
     the  Nyaaya  scheme.  It  is the  latter  which  the
     received  view upholds: it is the former  which  the
     incompatibilist vehemently opposes. The issue is not
     joined, because  surely one can maintain  that there
     is a deductive  inference  in the  inversion  Nyaaya
     scheme  without  maintaining  that  it captures  the
     meaning  of or even  approaches  synonymy  with  the
     original.  In sum, the issue  between  the  received
     view and the incompatibilist  pivots on the former's
     willingness to invert the Nyaaya form and read it as
     a valid deduction  and the latter's insistence  that
     the form cannot be so reversed  without  losing  the
     special relationship  of the hetu.  Given the merits
     of both views and given the fact that both positions
     are  not explicit  contradictories  of one  another,
     there is a way to understand the Nyaaya scheme which
     allows both sides to have their cake and eat it too.
     I believe  that  the three-membered  Nyaaya  is best
     understood   as   a   retroductivc   inference.   A
     retroduction, as  it has  been  described  by C.  S.
     Peirce and

              P.185

     Norwood  Hansonl  is a pattern  of  reasoning  which
     leads  from  some  phenomenon  or perception  to  an
