My goal in this paper is to show that two theses that are widely adopted among Kantian ethicists are irreconcilable. The paper is divided into four sections. In the first, I briefly sketch the contours of my own positive view of Kantian ethics, concentrating on the issues relevant to the two theses to be discussed: I argue that agents can perform actions from but not in conformity with duty, and I argue that agents intentionally can perform actions they take to (...) be contrary to duty. In the second, I focus on Barbara Herman’s non-accidental rightness condition from “On the Value of Acting from Duty.” In the third, I focus on Christine Korsgaard’s guise of the objectively good from “Formula of Humanity.” In the fourth, I explain why the positions developed by Herman and Korsgaard are irreconcilable and I make a suggestion about how to move forward.

Samuel Kerstein argues that an asymmetry between moral worth and maxims prevents Kant from accepting a category of acts that are impermissible, but have moral worth. Kerstein contends that an act performed from the motive of duty should be considered as a candidate for moral worth, even if the action's maxim turns out to be impermissible, since moral worth depends on the correct moral motivation of an act, rather than on the moral lightness of an act. I argue that Kant (...) cannot consistently maintain that there are morally forbidden, though good, acts since one of the conditions of acting from the moral law should be that one has a true belief about what the moral law requires. My project, then, rejects the possibility of morally impermissible, worthy acts for Kant, and qualifies the conditions for moral worth Kerstein gives with an epistemological constraint on moral worth.
