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.
