In this discussion I shall argue that some fairly widely held views about human habits are mistaken. These misconceptions are important because of the pervasiveness of the habitual in human behavior and because it is the concept of habit that has served as the prototype of various conceptions of conditioned response which are used in psychological explanation. One major task of this analysis is to show that accounts in which actions are explained by reference to rules are not incompatible with (...) accounts in which the same behavior is seen as the product of habit.
