In the late 1830s and early 1840s Hans. L. Martensen (1808-1884) helped to introduce the thought of G.W.F. Hegel to the intellectual world of Copenhagen. Between Hegel and Kierkegaard offers the first English translations of three important early writings of Martensen in the philsophy of religion. These treatises evidence an original and critical interpretation of Hegel's thought from a speculative theological point of view. The heart of Martensen'sphilosophy of religion is the idea of freedom or personality grounded in its relation to the divine. These writings exercised an important and formative influence on the young Kierkegaard, Martensen's student, even though Kierkegaard later became a formidable opponent and critic of Martensen.
