Heidegger wrote that human beings are the only beings for whom being is a problem. Kierkegaard wrote that an individual does more than merely exist, that an individual is “infinitely interested in existing,” and the philosopher Karl Jaspers had gone so far as to call his philosophy Existenzphilosophie.

In general, however, we can say that existentialism focuses on human beings embedded in the world as humans—that is, with such things as moods and bodies and fundamental concerns about their own existence—and that existentialists approach problems familiar from the history of philosophy, such as epistemology, cognition, and ethics, from this
