Immanuel Kant (AD 1724-1804) Immanuel Kant was a German philosopher who sought to respond to what he considered the failure of traditional metaphysics as well as the failures of idealism and skepticism. He called his solution a Copernican revolution. Rather than think our minds conform to the world, Kant thought that the world conforms to our minds. In addition to his work in epistemology, Kant also made a significant contribution to modern moral philosophy with his identification of the categorical imperative. Our seminarians study Kant their junior year in Epistemology and Ethics courses.
