Immanuel Kant (1724 –1804) was a German philosopher and one of the most important thinkers from the Enlightenment era. Having made comprehensive and systematic contributions in epistemology, metaphysics, ethics, and aesthetics, Kant is considered to be one of the most influential figures in modern Western philosophy. Among his most important works are 1781’s Critique of Pure Reason, 1788’s Critique of Practical Reason, 1797's Metaphysics of Morals, and 1790’s Critique of Judgment.
