Immanuel Kant was a German philosopher who is widely considered to be a central figure of modern philosophy. He argued that fundamental concepts structure human experience, and that reason is the source of morality. His thought continues to have a major influence in contemporary thought, especially in the fields of metaphysics, epistemology, ethics, political philosophy, and aesthetics. “The Metaphysics of Morals” is a work of political and moral philosophy. This work is about republican interpretation of origins of political community as civil society and establishment of positive law.
