ABSTRACT
Kant thought that a wholehearted commitment to morality is rational only if God exists and we are immortal. What does a wholehearted commitment to morality involve? The key is found in his concept of a morally good will. One’s will is good when one acts from duty, when the maxims on which one acts are morally lawful, and when one acts out of respect for the moral law. The three conditions are equivalent in the sense that if any one of them is met, so are the two others. But how are they to be understood?
