Abstract: Kantian ethics is based on principles that seek their foundation in the pure mind and its conceptual structure independent of experience and the self-representations that accompany it, refusing that nature or real experience be its starting point. Therefore, it was only natural that the premise should have a pure metaphysical idea: “freedom”, without which it is impossible to talk about the will. The will that generates the concept of “duty” as a culmination of its own action and its independence from the symptoms of real-world experience. Duty, as coercion exercised by the mind over free will, is embodied in absolute moral commands, the very orders that make a person a moral legislator, celebrated as “personal” respect for the moral law issued by him as a rational being and distinguished from other beings by his moral dimension. Through this respect for the moral law, a person acquires a dignity that rises above all beings and makes them an end in themselves.

   The nature of the interconnectedness that combines these characteristics is a concomitant interconnection, and freedom and will, and the duty and compassionate responsibility, respect and dignity can be considered attributes without which the moral Kantian person is not achieved, whereby a person is not a person unless he carries features that rise above his physical existence in nature and above beings Other belonging to it.

    The philosopher Nietzsche topped the list of critics of Kant and had his opinions in which he believed that Kant’s assertion that what is morally acceptable is what is acceptable to all is false or wrong; because, for Nietzsche, absolute morals can only exist if humans are of on natureThisisnottrue.
