title: Teleology and teleonomy in behavior analysis.
abstract: Teleological descriptions and explanations refer to purpose as consequent to a phenomenon. They become nonteleological if purpose is represented as antecedent to the phenomenon. Such nonteleological statements are called teleonomic, especially when they refer to antecedent genetic "programs." In behavior analysis, purpose is attributed to the organism's history of consequences. Such a history may leave a trace-physiological (mechanism) or mental (cognitivism)-or the issue of traces may be irrelevant (contextualism). The history or trace is antecedent to current responding, and thus is not a teleological concept in the classical sense. It could be called a teleonomic concept, but this designation is undesirable if it implies exclusively genetic programming, because the history or trace is genetically programmed in evolutionary selection but not in ontogenetic selection. Therefore, the concepts of teleology and teleonomy are not useful for behavior analysis, and invoking them can be misleading. The concept of purpose can be useful if it is not reified.
