The Failure of Philosophical Behaviorism Philosophical behaviorism failed because mental discourse cannot be successfully reduced to behavioral dispositions.
Mental beliefs form a wholistic network.
Any one belief that I have presupposes a rich background of other beliefs. For example say we claim that my dislike of rain is nothing more than a behavioral disposition. If it is raining out, then I will use my umbrella. It appears that these declarations of conditionals here could be continued infinitely. This infinacy does is not conducive to an effective reduction of mental events to behavioral dispositions.
