ABSTRACT
It is not clear which of Søren Kierkegaard’s writings Franz Rosenzweig (18861929) read, and explicit references to Kierkegaard are rare. Nonetheless, they clearly show that Rosenzweig highly appreciated him. Furthermore, a comparison of their writings shows that they are kindred spirits. Both of them can with justice be called existentialist thinkers. In order to demonstrate this, I will proceed in four steps. In a first step, I will present the few places where Rosenzweig explicitly mentions Kierkegaard. In a second step, I will describe how the relation between Kierkegaard and Rosenzweig has been portrayed in the twentieth-century secondary literature. In a third step, I will summarize the results of the most recent investigations. Finally, I will point to some desiderata of the research on Kierkegaard and Rosenzweig.
