An extraordinary book which is very much accessible to the educated and curious layperson. Roger Foster has distilled the genius of Theodore Adorno into a highly lucid and readable account. And what treasures lie within! Far from a pedantic excursus on inscrutable miscellany to promote an academic's career, we find the project to fill in the concept to fulfill its potential. To fix the hole in which rational discourse falls into and which positivism and instrumental science applauds, Adorno shows us how to embody the concept, to bring in the emotions, rhetoric and sensuousness to make it a living breathing thing, and Foster guides us along the way. Nothing less is at stake than meaning and the possibility of restoring dialogue, so we can finally go about solving our species' dire problems.
