Everything or anyone who is rational has will, be it a human being or a field mouse. Freedom is the property that possesses this causality. Therefore, a free will can be defined as a will that can act causally without being caused by external sources. Any action not based on some form of law would be considered unfounded and unjustified and we could therefore not say that our actions are the result of our own will. Kant adds to this point by saying that the laws on which we base our actions must be self-imposed. They cannot be imposed by external sources because otherwise our actions would be based only on natural necessity; we would simply react to external causes. To see how Kant's statement translates into saying that an autonomous will is bound by moral law, we must first understand what morality is and how it is achieved. Kant believes that morality is an a priori concept, that is, independent of any experience of the world. Morality comes from the idea of ​​“good will,” which Kant argues is the only truly “good” thing in the world. Rational beings can realize their will through imperatives or rules that rational beings follow to make their will necessary, whatever they want. Perhaps. There are two types of imperatives: the hypothetical imperative and the categorical imperative. Hypothetical imperatives are based on subjective principles of personal desire and desire, which is why hypothetical imperatives have no moral value. The categorical imperative, on the other hand, is unconditional and therefore completely a priori. It refers to actions that do not depend on anything but are necessary in and of themselves. We can achieve good will and therefore morality only by isolating our motivations and desires and acting for the sake of duty. To help… middle of the paper… freedom is the basis of the will of a rational being. Since we know that the universal principle of morality arises from the will of a rational being thanks to the Autonomy Formula, we can therefore conclude that freedom is the basis of the universal principle of morality. In a sense, rational beings are defined by our concept of freedom. As humans, we look at the world through the perspective of humans; what we know about the world comes from observations and experiences. Therefore, we cannot know what the world is really like. This may seem daunting, and Kant admits that freedom is simply a concept we apply to ourselves as rational beings, and therefore is something we can never be sure of. However, his argument allows us to understand that the fact that we govern ourselves according to this Idea of ​​Freedom demonstrates that rational beings, at least in our perspective, are truly free.
