An international team of leading philosophers explore the crucial notions that articulate Heidegger’s concept of authenticity, including death, anxiety, conscience, guilt, resolution and temporality. In doing so, they clarify the bearing of Division Two’s reflections on our understanding of intentionality, normativity, responsibility, autonomy and selfhood. These discussions raise important questions about how we may need to rethink the morals of Division One of , the broader project to which that book was devoted, the shaping influence of figures such as Aristotle and Kierkegaard, as well as Heidegger’s relationship with his contemporaries and successors. Essential reading for students and scholars of Heidegger’s thought, and anyone interested in key debates in phenomenology, ethics, metaphilosophy and philosophy of mind.
