Despite being the work of one of the 20th-century’s most famous philosophers, Jean-Paul Sartre’s Critique of Dialectical Reason has never been fully integrated into our collective philosophical consciousness. None of the book’s key concepts, from seriality to the group, have come to play an important role in other philosophers’, sociologists’, or political theorists’ work. Amongst Sartre scholars, while work on the Critique has increased steadily in recent years, in particular in France and Belgium, no critical consensus exists about the book’s (...) overall meaning or value. On the occasion of the Critique’s 60th birthday, in this article I provide a summary of its main aims and concepts with a view to establishing a new basis for reading and discussing the book. I will argue that the Critique is a coherent and unique work of social theory that speaks to a world suffering an overwhelming wave of what Sartre calls ‘counter-finality’ in the form of climate change.
