Kurth wants us to understand and appreciate our anxiety more than we typically do. His concise and crisply written monograph makes a good case that we should. It deepens our understanding of what anxiety is, and of how it animates different facets of our mental and moral lives. The case he builds that, roughly, anxiety is one of the brain’s ways of affectively signaling and responding to uncertainty is clearly argued and meticulously organized. Kurth hits the targets he sets for (...) himself, and advances his agenda in a way that I found largely convincing. The result is a book that is a must-read for anyone working on anxiety and other moral emotions, and that will reward anyone who is curious about the nature and value of this increasingly, and perhaps alarmingly, prominent component of our minds.
