Abstract
Jaspers' Groningen lectures of 1935. The first lecture presents a challenging interpretation of Kierkegaard and Nietzsche and their importance for the contemporary philosophical situation. Lectures 2, 3 and 4 develop the central notions of Jaspers' philosophy such as the Encompassing, communication, and the role of rational thought. The final lecture explores some of the implications of these views, in connection with the radical contributions of Kierkegaard and Nietzsche, for contemporary philosophizing.--D. R.
