Groundwork of the Metaphysic of Morals

If moral principles apply to everyone, in every situation, at all times, they must be based on concepts of reason rather than on culture or individual personality. "The Metaphysics of Morals" uncovers the principles that guide moral duties and determine the moral compass for good will. By explaining why actions are moral only if they are intentionally moral (not for ulterior motive) and why intention is more important than the outcome of an act (with respect to morality), Kant makes the case for a definable basis for human morality.
