Final answer:
Kant asserts that the moral law is comprised of categorical imperatives, universal ethical principles derived through reason that dictate certain perfect and imperfect duties.
Step-by-step explanation:
Immanuel Kant posits that the moral law consists entirely of categorical imperatives, which are principles that must be followed regardless of personal desires or ends. He believes these moral laws can be discovered through reason alone, and they serve as universal codes of ethical conduct. Kant identified categorical imperatives as being fundamental to morality because they are not dependent on any particular situation or outcome. These imperatives can be divided into perfect duties and imperfect duties. Perfect duties, such as not lying or committing murder, are those that one must always follow, while imperfect duties are those that one should follow as much as possible but may not be applicable in every situation.
