Immanuel Kant (1724-1804) was a German philosopher known for his influential contributions to metaphysics, epistemology, and ethics. In his seminal work, “Critique of Pure Reason,” Kant explored the limits of human knowledge, distinguishing between a priori and a posteriori knowledge. He introduced the categorical imperative in ethics, emphasizing universalizable maxims as the basis for moral actions. Kant’s metaphysical stance, known as transcendental idealism, posited that reality is shaped by the mind’s cognitive faculties. In “Critique of Judgment,” he examined aesthetic judgments and teleology in nature. Additionally, Kant made contributions to political philosophy, proposing ideas for perpetual peace among nations. His ideas have left a lasting impact, shaping discussions in philosophy, ethics, and political theory, with an enduring emphasis on individual autonomy and the primacy of reason.
