In the usage of Kant, a good will is the unconditional, intrinsic good, independently of what it ‘effects or accomplishes’ in the world (Groundwork of the Metaphysic of Morals ). It is the determination to act in accordance with the law of autonomy or freedom, that is, in accordance with universal moral law and regardless of selfish advantage. See also categorical/hypothetical imperative.
