  It may be wondered whether cognitive behavior therapy is consistent with behaviorist doctrine.  Much depends on how beliefs and desires are understood.  If beliefs and desires are understood as states that somehow spill out into the environment and are individuated in terms of their non-mentalistic, behavior-like role in organism/environment interactions, this would be consistent with traditional behaviorist doctrine. It would reflect the principle of logical or analytical behaviorism that if mental terms are to be used in the description and explanation of behavior, they must be defined or paraphrased in non-mental behavioral terms.  Prospects for belief/desire individuation in non-mental, environmentally externalist terms may look doubtful, especially in cases of conscious attitudes(see Horgan, Tienson and Graham 2006). But the topic of the forms and limits of behavior therapy and the range of its plausible application is open for continued further exploration.
