Abstract
Summary This paper provides an interpretation of the movement of Arendt's thought in her Denktagebuch, from 1950 to 1973. This movement results in an incipient political philosophy based on new concepts of freedom, equality, and solidarity. As a contribution to debates on the normative foundations of Arendt's political thought, the paper seeks to show that her incipient political philosophy is based on an ethical understanding of the human condition as constituted by its openness to the divine, the worldly, and the (human) Other. Despite its fragmentary nature and its politically problematic indebtedness to theological traditions, Arendt's private thought nevertheless allows us to rethink her place in the history of European ideas. Beyond that, it also provides a powerful alternative to the view that ethical and political thought must remain ?political not metaphysical?
