Returning to NBN is the philosopher Santiago Zabala, here to introduce his new book Signs from the Future: A Philosophy of Warnings (Columbia University Press, 2025). Warnings, for Zabala, are not synonymous with predictions. They are instead as much about the present as the future. They point towards already present crisis and contradictions. They also attempt to reorient us towards alternative paths. Embedded deeply in the critical hermeneutics of writers such as Heidegger, Arendt and Beauvoir but exploring contemporary issues such as gender, climate change and machine warfare, Zabala’s book is an accessible and applicable text that simultaneously tries to destabilize us in our present complacency while grounding us in an urgent need to seek alternatives. Santiago Zabala is ICREA Research Professor of Philosophy at the Pompeu Fabra University in Barcelona. He is the author of numerous books, including one previously discussed on this show, Being at Large: Freedom in the Age of Alternative Facts.
