 Recapping, on one authorship view of action, an action is a prediction being enacted in part on the basis of a designated motivation, and practical reasons are the explanatory support for such predictions. And a second such view is held to support a theory on which only universalizable maxims count as practical reasons. We are also seeing that authorship views of action may have strikingly different philosophical motivations: in one case, to account for the bindingness or normativity of reasons; in the other case, to assimilate practical to theoretical reasoning, as well as a need to make room for a certain sort of first-person authority about one’s will.
