Santiago Zabala asks us to think of philosophy as a warning, a call to heed ominous “signs from the future.” He argues that warnings - as distinct from predictions - invite us to see the possibility of a radical break from the present. It places thinkers such as Nietzsche, Heidegger, de Beauvoir, and Arendt into conversation with present-day politics, art, and culture, drawing our attention to unheeded warnings.
