Abstract

This paper is a rejection of parsimonious behaviorism (PB). PB was proposed by Stemmer (2003) to avoid certain problems with radical behaviorism's (RB) appeal to covert behavior to account for mental phenomena. According to Stemmer, covert behavior was not clearly defined and its existence was not supported by empirical evidence. However, overt behavior is not as undefined, nor its existence as empirically unsupported as Stemmer claimed. Nor does PB avoid the problems, as it does not encourage us to seek a definition or empirical evidence that supports this existence. Moreover, Stemmer did not define the entities he accepted as existent (physiological traces), nor did he cite empirical evidence that supported their existence or his proposed interpretation of mental phenomena. Also, his claim that PB is more parsimonious than RB rests on a fallacious acceptance of the existence of physiological traces and a misinterpretation of the explanatory role of physiological events in RB. Finally, Quine's repudiation theory does not avoid the questions of the status, nature, and location of mental entities in identity theories. Such questions are not fundamentally different from those raised by material entities in general. The questions are thus faced by any materialist position, Quine's repudiation theory included
