ABSTRACT
Following the traditional distinction in axiomatics between theories and systems themselves, there are two basic kinds of behaviorally relevant theories of knowledge. This chapter taxonomizes and characterizes descriptions of behavior. It specifies the nature of the stimuli (inputs) and responses (outputs) to which the theory relates. The chapter defines precisely what is meant by rules and their extensions. It identifies some of the kinds of higher order rules allowed in the theory. The chapter specifies the form of the theory itself including the laws governing the interaction among rules, and illustrates the theory. It suggests a general axiomatization and proposes some conjectures. The theory so defined provides a schema to which specific realizations of the theory must conform. Any particular realization of the theory involves a finite set of rules which, given the laws governing their interaction, accounts for the behavior of interest.
