This chapter proposes a narrative theory of action. From a narrative perspective, actions are viewed as meaningful expressions which are integrated into a larger whole: the story of life. Explanation of action takes the form of interpretation or hermeneutic understanding. The phenomenology of Merleau-Ponty provides an example of a narrative approach to human action. The notions of dialogue and style in Merleau-Ponty's philosophy are especially relevant. A narrative theory of action may actually play a role in contemporary human sciences. Such a role is demonstrated through a discussion of a possibile narrative approach to the psychology of addiction.
