Approaches to the study of human behavior epitomized by objectivism and subjectivism are judged inadequate due to the a priori categories which they presume, and an alternative is demonstrated with two case studies. The first explores the structure of subjectivity underlying Downs's (1957) theory of voting, and the second reveals the same operant forms implicit in Zetterbaum's (1982) philosophy of the political self. Discussion follows on the ramifications for a science of subjectivity.
