A discussion of Pettit, Philip, A Theory of Freedom: From the Psychology to the Politics of Agency, Cambridge, Polity Press, 2001. In Philip Pettit’s “A Theory of Freedomâ€, Pettit claims that being free to do something is being held responsible for what we do; so whatever theory of freedom we develop must allow the agent to be held responsible for the free actions that they do. In this paper I am going to examine Pettit’s claim about what a satisfactory theory of freedom would require, and discuss several ambiguities within the theory. However, within this reading two major interpretations may be taken: the first of which suggests that freedom can only be freedom when there is a moral ‘ought’ involved; the second is a more generous reading in which freedom includes all realms of responsibility.
