Establishing the metaphysics of morals

In his book "Foundation of the Metaphysics of Morals," the German philosopher Immanuel Kant reviews his radical ideas about ethics, presenting a new vision of the moral system that focuses on the principle of freedom. Kant believes that morality cannot be absolute without the existence of freedom of will, as submission to the law that a person establishes for himself is considered a basic condition for performing any moral act. The book highlights the importance of treating humanity as an end in itself, rather than a means to achieve other goals. The book deals with profound reflections on the nature of duty and reason, emphasizing that morality is not merely external rules but an expression of one''s conscience. In simple terms, this work of Kant represents a turning point in moral philosophy, laying the foundations for understanding human behavior from a rational and principled perspective.
