violation of the Categorical Imperatives according to Kant. Korsgaard goes against Kant’s assertion that it is wrong to give the murderer at the door the wrong answer arguing that it does not violate the Categorical Imperatives to lie in these circumstances. She further discusses that it is a duty to lie to the murderer at the door and expands on her reasoning. Korsgaard comes up with a two level theory on which the first form of the Categorical Imperative would apply under all circumstances and the second only when one is defending oneself or another against evil.In order to defend Kant’s first Categorical Imperative, Korsgaard argues that it is in fact permissible from a Kantian point of view to universalize the maxim, or principle that governs action, when lying to the murderer at the door. She argues that the first form of the Categorical Imperative is not violated in the case where the murderer makes a secret of their murderous intensions. She explains that if the murderer at the door does not know that the recipient knows they are murderers, that the murderer will think that the recipient will believe that they are just a “friendly neighbor trying to find out where their friend is” for example. In other words, she believes you can universalize a maxim in which you respond to evil with an effort to frustrate evil through deception, where the evil person is unaware that you are aware of his plan. The evil person, or murderer, does not realize that you are in the position in which you would use this maxim; therefore you would be able to use this without frustrating your purpose to successfully get away with your lie.
