Lying from Kant’s Point of View

This paper discuss moral judgment of lying from Kant’s point of view. According to Kant, Lying is a great vice and the key of all evils. He define lying as “to tell something which is not in your heart”. Most of the people think that lying is wrong due to its harms to others, but Kant says that lying is wrong even if it does have any harm to others and has been told by good intention. He knows lying wrong because of destroying human worth. He counts not telling the lie as a perfect human duty to others and to oneself. The main question of this research is this: is lying prohibited absolutely from Kant’s view or he permits some kind of lies?  The result of this research shows Kant has different views on lying in his different works. He permits some kind of lies in his former works like Lectures on Ethics and says that lying and deception is permitted in defense of oneself. But, in his later works like Groundwork of the Metaphysics of Morals and “On a Supposed Right to Lie from Altruistic Motives”, Kant makes lying absolutely prohibited.
