Quizplus · Accepted Answer

According to Kant, the fundamental principle of morality is the categorical imperative, which states that one should act only on maxims that are universalizable. This means that a moral action should be one that could be made into a universal law without contradiction. For example, lying cannot be made into a universal law because if everyone lied all the time, trust and communication would break down. Therefore, morality requires us to act in a way that is consistent with universal principles, regardless of our personal desires or interests.
