Query: Kirkus?

My girlfriend is reading this book, I've only skimmed it briefly. I do detect a tendency on Pearce's part to be anti-scientific, and to make claims without giving evidence. In any case, who are the "Kirkus" reviewers that the other reviews lambaste? Seems odd that they are represented only by their detractors...
