This paper addresses some of the characteristic concerns of Jaspers' and Heidegger's philosophical projects. The relation between the two thinkers is presented as a history of misunderstanding, yet also as a history of their respective interest in the existentiell aspect of philosophy.
In analyzing Heidegger's and Jaspers' works, I present the ideas of "abstraction" and "theology" as the two extreme limits of the conceptual field within which their thinking evolves. After doing so, I make the suggestion that the ethos of their philosophy draws heavily from the heritage of Kierkegaard's project of the subjective thinker.
