Given the large literature on Frege, one might believe that it would be impossible to say anything essentially new on the subject. This book contradicts this belief.... This book is a welcome addition to the literature on Frege. It fills the gap that most secondary literature on Frege has left open by not paying close enough attention to what Frege says about thinking. In this way it shows that, despite the large literature on Frege, it is still possible to say something essentially new on the subject.
