Step-by-step explanation:
Immanuel Kant believed that morality comes from the authority of reason alone. He argued that moral laws can be discovered a priori, using our reason to determine what is right and wrong. Kant formulated the concept of categorical imperatives, which are universal principles that can be applied to everyone without exception. These categorical imperatives serve as the foundation for ethical behavior and guide individuals to identify moral codes that can lead to an improved society.
