This discipline has become more reflective in recent years. It has also
become blatantly philosophical, which is itself cause for reflection.
The philosophy of psychology has not been exactly a burgeoning field,
and yet psychologists and philosophers of all persuasions are writing
philosophical psychology. Perhaps all this activity merely reflects the
uneasy bifurcation of psychology into biological and cognitive domains.
After all, there were similar flurries in the 1920s and 1950s when the
discipline assumed new directions. But, before, there were too many
things to do; scientific knowing seemed so compelling and so singular in
methodology. Today, the entire enterprise is much more uncertain, and
not just psychology, but all human scientific inquiry. The fun- damental
questions remain much the same, of course; what has changed is that
philosophers are explicitly addressing questions of psy- chology and
psychologists are at least implicitly engaged in philosophy. The
bounderies are no longer clear cut! Theoretical psychology is as much
the doing of philosophy as it is of experimental research. Volume 4 of
these Annals attests to this state of affairs. The psychologists' style
reflects their philosophical understanding; the philosophers differ
according to what they take to be psychological knowledge.
