This review by Jill Vance Buroker concludes with: "This book should not have been published because it adds nothing to the literature. It is difficult to imagine a Kant specialist recommending its publication."
The review looks fair to me because it offers a whole number of arguments for the conclusion. (I have some minor quibbles, but I am no Kant expert.) While I might not have used those exact words, I believe that critical book-reviewing plays an essential role in the discipline's quality control. What do readers think? I prefer signed comments on this one.
