 Even with a system of moral duties in place, Kant admits that judgment is often required to determine how these duties apply to particular circumstances. Moral laws, Kant says, “must be meticulously observed” but “they cannot, after all, have regard to every little circumstance, and the latter may yield exceptions, which do not always find their exact resolution in the laws” (V 27:574; see also CPR A133/B172; MM 6:411).
