Metaphysics Morals

Immanuel Kant's Fundamental Principles of the Metaphysics of Morals, first published in 1785, lays out Kant's essential philosophy and defines the concepts and arguments that would shape his later work. Central to Kant's doctrine is the categorical imperative, which he defines as a mandate that human actions should always conform to a universal, unchanging standard of rational morality.

Immanuel Kant (1724-1804) was one of the most influential philosophers of all time. His profound thoughts on aesthetics, ethics, and knowledge has had an enormous impact on all subsequent philosophy. Kant asked questions like “What is morally permissible, and what is morally obligatory?” and explored the answers in Fundamental Principles of the Metaphysics of Morals. Kant's idea of the categorical imperative is a logical proof of the golden rule and the centerpiece of this work.

Fundamental Principles of the Metaphysics of Morals (1785) remains one of the most influential works on moral philosophy. The German philosopher Immanuel Kant sets out by explaining the core concepts and principles of moral theory and demonstrating that they are normative for rational agents. He argues that the world of understanding is more fundamental than the world of sense. Therefore the moral law, which clearly applies to the world of understanding, also applies to the world of sense because the world of understanding is primary.

Groundwork of the Metaphysics of Morals (1785) is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most important in the field. Kant examines the core concepts and principles of moral theory, showing that they are normative for rational agents. He aspires to lay bare the fundamental principle of morality and prove that it applies to us. Kant offers the argument that the rightness of an action is determined by the character of the principle that a person chooses to act upon. 

Groundwork of the Metaphysics of Morals is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most influential in the field. Kant conceives his investigation as a work of foundational ethics - one that clears the ground for future research by explaining the core concepts and principles of moral theory, and showing that they are normative for rational agents.
