ABSTRACT
In this chapter we consider current developments and future directions in reasoning research suggested by the approach we have been developing in this book. We first discuss recent empirical developments, including new areas of human reasoning that are susceptible to a probabilistic analysis. We also trace the relation between our research programme and recent empirical work on probabilisitic reasoning. Second, we look at wider theoretical issues relating to a probabilistic account. Specifically we consider the extent to which the probabilistic approach deals with the problems of completeness* and tractability that framed the discussion of logicist cognitive science in Part I. We also consider the relations between our approach and some influential recent proposals concerning human rationality.
