The end of plasticity

Abstract

Paul Churchland has become famous for holding three controversial and interrelated doctrines which he put forward in early papers and in his first book. Scientific Realism and the Plasticity of Mind (1979): eliminative materialism, the doctrine of the plasticity of perception, and a general network theory of language. In his latest book, The Engine of Reason, the Seat of the Soul (1995), Churchland aims to make some results of connectionist neuroscience available to the general public and explores the philosophical and social consequences that neuroscience is likely to have. I argue that these results of neuroscience refute the three doctrines that Churchland advocated in his earlier works. Yet youthful dreams do not die easily and Churchland is reluctant to relinquish his early views.
