In the third section of the Groundwork of the Metaphysics of Morals, Kant attempts to justify the validity of a categorical imperative. In his argument, he introduces the idea of "two standpoints" that rational beings can take. From one standpoint, rational beings understand themselves as free, and from the other they understand themselves as subject to the laws of nature. I discuss that the introduction of this idea marks an argumentative turning point from the theoretical to the practical context. For this purpose, I argue that taking a standpoint implies in itself the activity of an agent that has their own free will.
