Max Weber, who was a well-known sociologist both of his own time and of today, has been one of the most influential names – besides, Immanuel Kant, Søren Kierkegaard, and Friedrich Nietzsche - for Karl Jaspers, who is one of the original names that come into minds when the 20th-century existential philosophy is mentioned. In fact, it can easily be asserted that Weber had a huge personal role in Jaspers’ carrier as a philosopher. Karl Jaspers is known for his uniquely discussed concepts such as freedom (Freiheit), communication (Kommunikation), Existenz, limit situations (Grenzsituationen), the encompassing (das Umgreifende), guilt (Schuld), and responsibility (Verantwortung). And it is obvious that Jaspers was affected by Weber considering his two specific concepts: guilt and responsibility. This is the case because Jaspers himself explains how and in what ways he was influenced by Weber. In this article, we will discuss Weber from the perspective of Jaspers. This discussion will be held in two aspects: i) personal features of Weber given by Jaspers, and ii) Weber’s effects on Jaspers from the viewpoint of Jaspers and what they share considering politics and ethics at the theoretical level.
