The discredit into which the socialist ideal has fallen as a consequen
ce of recent political events calls into question, not just the viabil
ity of a particular political and economic system but, the very idea t
hat the social order can be improved by applying principles derived fr
om the scientific study of human social behavior. Before the collapse
of socialism, the idea of a science of human behavior, construed in bi
ological terms as a branch of the science of the behavior of free-movi
ng living organisms in general, had been undermined by Chomsky's (1959
) repudiation of the behaviorist project to construct a science of lan
guage (verbal behavior) based on principles derived from the study of
animal learning. I contend that only by reinstating the link between l
inguistics and the study of animal learning can confidence be restored
in the possibility of a genuine science of human behavior with applic
ation to the problem of constructing a better social order.
