Answer:
a. Kant's moral theory is fundamentally different from Mill's utilitarianism:
Kant's ethics are deontological, focusing on duty and the moral worth of actions. He believes that actions are right or wrong based on whether they conform to rational and universal moral rules, regardless of the consequences.
In contrast, Mill's utilitarianism is consequentialist, where actions are judged by the overall happiness they produce. The consequences determine the morality of an action.
b. Kant's means-end principle means we should treat people as ends in themselves, not just as a means to an end. In the case of a lying promise, Kant would say it's wrong because it treats someone as a tool to achieve your goal rather than respecting their intrinsic worth and autonomy.
c. Kant believes the only thing that is unconditionally good is a "good will." This means having a will or intention to do what's morally right out of a sense of duty, regardless of the consequences. Other things, like talents or happiness, are only good if they're used in line with a good will.
