This expanded edition of James Ellington's preeminent translations of Grounding for the Metaphysics of Morals and Metaphysical Principles of Virtue includes his new translation of Kant's essay On a Supposed Right to Lie Because of Philanthropic Concerns, in which Kant replies to one of the standard objections to his moral theory, as presented in the main text of Grounding , that it requires us to tell the truth even in the face of harmful consequences.
