This is a great book but I felt something cold inside of me while reading it. I don't know if it is cultural (the modern English philosopher's fear of displaying passion) but I had the feeling to talk to a plumber who developed expertise in abstract concepts and their relationships just as if they were small plumbing problems fitting together under a generalized plumbing theory. Perhaps philosophy needs to be treated like that, just like engineering --but not for me. At least I give myself the illusion of doing something more...literary.
Colin McGINN teaches us that we need nevertheless to master the art of clarity of both thought and exposition. He write with perfect clarity: a clear, unburdened, unaffected, UnFrench UnGerman philosophical prose.
The book has a presentation of the Kripke idea of naming as necessity of such clarity that I felt actually smart reading it.
Other than that there is the feeling of drabness in part of the book of the type I got once at a conference in an industrial city West of London.
