The essay presents Patočka’s intellectual relationship to Karl Jaspers on the basis of his texts from the 1960s and 1970s, with a starting point in the 1969 study What is Existence?. After introducing some general connections and differences, based in particular on the forms of heresy in both philosophers, the basic contours of the notion of existence are examined more closely. Patočka understands existence as the performance of a threefold movement that is in many respects problematic. The virtue of Jaspers’ (...) position, on the other hand, lies in its focused clarity. While both thinkers emphasize the concept of authentic performance, the key issue becomes its one-sidedness, which can be described as surrender without acceptance. (shrink)
