This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work of ethics, The Groundwork for the Metaphysics of Morals. Specifically it examines his discussion of the distinction between three modes of presenting what he terms the "principle of morality" - one focused upon universality of the maxim of one's will, one on treating human beings as ends not just as means, and another focused upon a possible kingdom of ends.
