Abstract

The Rules of Thought, by Jonathan Jenkins Ichikawa and Benjamin Jarvis, is a dense and ambitious book whose principal aim is to defend the view that philosophical inquiry is a priori inquiry into essential natures. The book covers a broad range of philosophical issues spanning the philosophy of mind and language, the epistemology of metaphysical modality and the philosophy of philosophy. It will be of considerable interest to many, since there is something in it for just about everyone. That said, the authors do not do as much as one might like to make their views accessible to the uninitiated or convincing to the unconverted.
