Kant's Groundwork for the Metaphysics of Morals, first published in 1785, is still one of the most widely read and influential works of moral philosophy.This Broadview edition combines a newly revised version of T.K.Abbott's respected translation with material crucial for placing the Groundwork in the context of Kant's broader moral thought.A varied selection of other ethical writings by Kant on subjects including our moral duties, fundamental principles of justice, the concept of happiness, and the relation of morality to religion are included, along with important criticisms of Kant's ethics by Fichte, Schiller, Hegel, and Sidgwick.
