With his innovative research on Kant and German Idealism, Eckart Förster has been a major driving force in research on idealism for many years. In particular, his works on Kant's 'Opus postumum' and spatial schematism, on intellectual intuition and intuitive understanding, on Fichte, Hölderlin, and Goethe, on the genesis of Hegel's Phenomenology of Spirit as well as on the importance of Goethe for post-Kantian philosophy have received widespread attention. This volume contains many of his most important essays from the last three decades.
