Immanuel Kant was a German philosopher who is widely considered to be a central figure of modern philosophy. He argued that fundamental concepts structure human experience, and that reason is the source of morality. His thought continues to have a major influence in contemporary thought, especially the fields of metaphysics, epistemology, ethics, political philosophy, and aesthetics. “The Critique Of Judgement” is one of the most important works of moral philosophy ever written. 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.
