Empathy (Einfühlung)—as a crucial concept for understanding ourselves, others, and communities—was a central topic of interest in the first half of the twentieth century amongst philosophers and in the emerging sciences of psychology and sociology. Edith Stein's dissertation and inaugural publication, On the Problem of Empathy, introduces her unique take on empathy, embodiment, phenomenology, and intersubjectivity. Her immersion in phenomenology and her intimate familiarity with the psychology and sociology of her day make it a challenge for contemporary readers to understand. This companion provides a guide to Stein's first philosophical masterpiece. The opening essays, including a contribution from Íngrid Vendrell Ferran, indicate the most important influences on Stein's thought circa 1917, the structure and method of her argument, the place of this work in her oeuvre, its historical significance, and its relevance for contemporary philosophical discussions. Timothy Burns then provides a clear and detailed summary of each section of Empathy, elucidating the argument that weaves through this classic of philosophical thought.
