This book is a very timely reminder that philosophers must avoid practicing philosophy as a normative discipline. Everyone can and should argue for what he or she considers to be right and true and important. But this should not be confused with philosophizing. The main responsibility of philosophy lies in questions of sense and intelligibility, as Ramal argues with Wittgenstein, Cavell, and Phillips. It must be oriented to the ordinary, to the life-world in which we know from our common practice what we mean by our concepts. Whenever philosophers confuse their own rational constructions with the reality they seek to reconstruct, they commit the fallacy of logical inversion. Whitehead, Rorty, Rosen, and many others have fallen into this trap, as Ramal demonstrates in detail. His clear, wide-ranging, and well-argued book sharpens the eye for the blind alleys into which philosophy gets if it does not avoid this fallacy.
