According to Kant each person has an empirical character, which is ultimately grounded in one’s free choice. The popular Causal Laws interpretation of empirical character holds that it consists of the causal laws governing our psychology. I argue that this reading has difficulties explaining moral change, the ‘gradual reformation’ of our empirical character: Causal laws cannot change and hence cannot be gradually reformed. I propose an alternative Causal Powers interpretation of empirical character, where our empirical character consists of our mind’s causal powers. The resulting picture of empirical character allows for moral change and Kantian weakness of will.

This paper gives an account of the argument of Schopenhauer's essay On the Freedom of the Human Will, drawing also on his other works. Schopenhauer argues that all human actions are causally necessitated, as are all other events in empirical nature, hence there is no freedom in the sense of liberum arbitrium indifferentiae. However, our sense of responsibility or agency (being the ‘doers of our deeds’) is nonetheless unshakeable. To account for this Schopenhauer invokes the Kantian distinction between empirical and intelligible characters. The paper highlights divergences between Schopenhauer and Kant over the intelligible character, which for Schopenhauer can be neither rational nor causal. It raises the questions whether the intelligible character may be redundant to Schopenhauer's position, and whether it can coherently belong to an individual agent, suggesting that for Schopenhauer a more consistent position would have been to deny freedom of will to the individual.
