And now I must say that if I contemplate what Ethics really would have to be if there were such a science, this result seems to me quite obvious. It seems to me obvious that nothing we could ever think or say should be /the /thing. That we cannot write a scientific book, the subject matter of which could be intrinsically sublime and above all other subject matters. I can only describe my feeling by the metaphor, that, if a man could write a book on Ethics which really was a book on Ethics, this book would, with an explosion, destroy all the other books in the world.
