Kant's Critique of Utilitarianism and a Maxim put through the categorical Imperative.

Kant's critique of Utilitarianism is that it treats people as a means not as an ends in themselves. Since he is a deontologist he presumes that there is a universal moral imperative, certain ways in which we must act, no matter what our individual desires or needs or utility might be. The Categorical Imperative is an idea of reason. This knowledge is not derived from experience but rather, it is a priori. It also binds …

…Imperative "reveals to us our freedom and dignity", by this he means that Dignity brings about your morality which is what makes you part of the Kingdom of ends. It frees us from our senses by making us realize our own nature. The Categorical Imperative reveals what is moral and immoral and therefore we are able distinguish the two and this allows us to be autonomous and if you are autonomous then you are free.
