In this article, I confront Parfit’s Mixed Maxims Objection. I argue that recent attempts to respond to this objection fail, and I argue that their failure is compounded by the failure of recent attempts to show how the Formula of Universal Law can be used to demarcate the category of obligatory maxims. I then set out my own response to the objection, drawing on remarks from Kant’s Metaphysics of Morals for inspiration and developing a novel account of how the Formula of Universal Law can be employed to determine the deontic status of action tokens, action types and maxims.

强制性行动，强制性格言

在这篇文章中，我面对 Parfit 的混合准则异议。我认为最近对这一反对意见作出回应的尝试失败了，并且我认为，最近尝试表明如何使用普遍法公式来划分强制性准则的类别的尝试失败使他们的失败更加复杂。然后我根据康德的评论阐述了我自己对反对意见的回应道德形而上学以启发并开发一个关于如何使用宇宙法则公式来确定动作标记、动作类型和格言的道义状态的新颖解释。
