Abstract
As philosophers we should have as one of our aims to produce as much philosophical knowledge as possible. A lot of potential philosophical knowledge is lost because of the flaws of the peer review system, and so a lot of philosophical knowledge would be gained were the system improved. Accordingly, as authors we should write papers about how to fix peer review, and as editors we should accept such papers if they are good. This paper presents some familiar problems with peer review, elaborates on and motivates the argument just given, and replies to some objections to it, making the case that fixing peer review is both a philosophical problem and one that admits of a solution.
