Immanuel Kant is not only the most influential philosopher of the late 18th century, but he is also the classical philosopher of modernity. Herbert Schnädelbach introduces Kant's complete works: in his discussions on Enlightenment and science, on metaphysics and critical reason, on practical reason and judgment, and he traces the lasting impact of the great thinker to this day. A concise, easily understandable introduction aimed particularly at undergraduate students.
