Kant's Theory of Action

The theory of action underlying Immanuel Kant's ethical theory is the subject of this book. What 'maxims' are, and how we act on maxims, are explained here in light of both the historical context of Kant's thought, and his classroom lectures on psychology and ethics. Arguing against thecurrent of much recent scholarship, Richard McCarty makes a strong case for interpreting Kant as having embraced psychological determinism, a version of the 'belief-desire model' of human motivation, and a literal, 'two-worlds' metaphysics. On this interpretation, actions in the sensible world arealways effects of prior psychological causes. Their explaining causal laws are the maxims of agents' characters. And agents act freely if, acting also in an intelligible world, what they do there results in their having the characters they have here, in the sensible world. McCarty additionally showshow this interpretation is fruitful for solving familiar problems perennially plaguing Kant's moral psychology.
