He cannot succeed, though, according to Kevin, because "the method in the Tractatus presupposes a view of language and philosophical confusion that is far too narrow." The book is too intellectualist, and tries to do its work by showing us what a sentence is.
If the (relevant part of the) book consists entirely of nonsense, though, then it surely cannot hope to show us what a sentence is. It can at most show us what a sentence is not. That is, if you start with a certain idea of what a sentence is and then follow that through until you end up in patent nonsense then you have shown that the original idea was wrong. But you can't show what we ought to believe instead in this way. Kevin isn't talking about what the Tractatus says about language, though, but about what its method presupposes. If it aims to show that all attempts at ultimate justification in logic, metaphysics, and ethics are illusory then he is probably right. But if the aim is as Conant describes, i.e. if the aim is to show the reader something, not to show something completely general, then whether it succeeds or fails will surely depend on the reader. And Wittgenstein says that:
This book will perhaps only be understood by one who has himself already at some time thought the thoughts that are expressed herein – or at least similar thoughts. –It is therefore not a textbook.—Its end would be reached if it gave pleasure to one person who read it with understanding.If the reader has the right confusions then I don't see that Kevin has given any reason to think the book cannot work as intended on him (the suitably confused reader). Can a book like this bring about change in how one lives? Well, I don't see why not. If one's problems are intellectualist then an intellectualist book might be just the thing. Of course it might not work. One might give up one kind of intellectualist wrong path only to take up another. But I don't see that failure is guaranteed.
