Immanuel Kant's Groundwork of the Metaphysic of Morals

According to the formula of autonomy, every rational agent is universal and no experience can determine universality. A rational agent may ‘will’ to act a certain way, but because they are rational beings free from sensual temptations, their ‘will’ is what imperfectly rational people ‘ought’ to act. Therefore, a rational agent’s ‘will’ becomes a universal law in which people guided by empirical experiences should abide. A rational agent is only autonomous when one can make judgments not by external “impulsion,” but by “pure practical reason.” Just as Kant states good will is a will “good in itself,” he believes a rational agent is “an end in itself” who becomes the author of the universal law which he will obey and the rest will follow. If a person can act as if one is a law-maker of a “kingdom of ends” who can be responsible for the universal law of one’s people,
