Abstract

Skinner has repeatedly asserted that he does not deny either the existence of private events or the possibility of studying them scientifically. But he has never explained how his position in this respect differs from that of the mentalist or provided a practical methodology for the investigation of private events within a radical behaviorist perspective. With respect to the first of these deficiencies, I argue that observation statements describing a public state of affairs in the common public environment of two or more observers which those observers confirm as a correct description provide a far more objective and secure foundation for empirical knowledge than statements describing private events in the experience of a single individual. In the course of this argument, I also invoke Wittgenstein's (1953) demonstration — his 'private language argument' — of the incoherence of traditional subjective empiricism. Regarding the second deficiency, I argue that observation statements describing private events can serve as data for an objective study, provided that (a) the verbal behavior in which they consist and its context are objectively observed and recorded, and (b) an explanation is given of how this verbal behavior is generated by the events it reports
