The author defends his version of the parallel which can be drawn between Wittgenstein's 'private language' argument and the argument that practical reasons must necessarily be public reasons. This position is compared and contrasted with recent attempts by Christine Korsgaard and Ken O'Day to formulate a 'public reasons' argument. The position is defended against the criticism that it cannt account for the practical force of reasons. Finally it is argued that, although the claim that the reasons must be 'public' is (...) not to be confused with the claim that reasons must be 'other-regarding', the former claim does help to remove certain obstacles to the idea of other-regarding reasons.
