[Philosophy] is also one of the most competitive disciplines. When I was a science editor I sometimes saw readers’ reports on colleagues’ philosophy manuscripts. There were often pages and pages of challenges to the authors’ arguments, concluding with a recommendation to publish anyway. This could be confusing to faculty editorial boards that approved or rejected books. It had to be explained to them that philosophers honor each other by disagreeing with each other. The number of objections could be a sign of the importance of the arguments. From such experiences I learned the difference between the merely wrong, and the valuable wrong.
