Witnessing with Courage: Radical Hope in Etty Hillesum’s Diaries

This paper examines the notions of moral fortitude and transformative hope in the diaries and letters of Etty Hillesum, a young Jewish writer who lived through the Holocaust. Drawing on Jonathan Lear’s concept of “radical hope,” understood as a commitment to goodness beyond present comprehension, the study situates Hillesum’s writings within an ethical framework shaped by crisis and cultural devastation. Rather than interpreting her optimism as naïve or escapist, the paper argues that Hillesum’s response to suffering embodies a conscious, ethically grounded resilience that aligns with an expanded Aristotelian understanding of courage. By distinguishing between mere optimism and ethically rooted hope, the study shows that Hillesum’s outlook exemplifies what Lear terms “radical hope”, a forward-looking openness to meaning when conventional frameworks collapse. The paper positions Hillesum as a moral witness whose writings offer profound insights into human dignity, ethical responsibility, and the possibility of sustaining meaning under extreme conditions. Her diaries emerge not only as historical testimony but also as philosophical texts that redefine courage and hope in the context of modern catastrophe.
