Over the years, many scholars have focused on the hierarchical and overpowering influence of Martin Heidegger upon Hannah Arendt’s thought. This view follows the stereotype concerning philosophical influence in which an all-knowing teacher affects the thought of the student, particularly if the student is a woman. In this paper, I argue that the story of philosophical influence is more complicated. In this case, the biographical archive establishes how Karl Jaspers, Martin Heidegger, and Hannah Arendt mutually influenced one another throughout their lives and careers. This evidence contests the typical view of philosophical influence which is hierarchical and often gendered and suggests a new model for understanding philosophical influences as dynamic and reciprocal.
