Final answer:
Kant argued that happiness is not good without limitation because it is based on subjective and conditional factors. True goodness lies in the will to act from duty alone, rather than pursuing happiness as an end in itself. Moral actions should be guided by rationality and the principle of universalizability.
Step-by-step explanation:
Kant argued that happiness is not good without limitation because it is based on subjective and conditional factors. According to Kant, true goodness lies in the will to act from duty alone, rather than pursuing happiness as an end in itself. Happiness can change and vary from person to person, making it an unreliable basis for moral decision-making. Instead, Kant believed that moral actions should be guided by rationality and the principle of universalizability.
