Skinner has been criticized for advancing essentialist interpretations
of meaning in which meaning is treated as the property of a word or a
grammatical form. Such a practice is consistent with a ''words and th
ings'' view that sought to advance an ideal language as well as with S
-R views that presented meaning as the property of a word form. These
views imply an essentialist theory of meaning that would be consistent
with Skinner's early S-R behaviorism. However, Skinner's more develop
ed account of meaning is based on his later selectionist behaviorism,
and this account of meaning is aligned in many respects with the views
of Darwin, Peirce, F. C. S. Schiller, Dewey, and Wittgenstein. After
adopting a selectionist theory of meaning, it was inconsistent for Ski
nner to maintain essentialist practices although Skinner did so in res
ponse to influences that had little to do with his selectionist theory
. Skinner's particular contribution to this pragmatic-selectionist tra
dition of meaning is the integration of meaning within his three-term
contingency for operant behavior. In this account, meaning lies in the
probabilistic functional relations of verbal behavior rather than in
its form.
