IS Wittgenstein correct here ?

A book was recently published that has shaken the Philosophy World,

Metaphysics and Grammar
by William Charlton


===============
Like everything metaphysical the harmony between thought and reality is to be found in the grammar of the language. Ludwig Wittgenstein

Here are two representative reviews by bright lights in the philosophy world:
“William Charlton's thesis that to understand the topics of metaphysics is to understand the grammar of our language sets him radically at odds with most contemporary metaphysics and most contemporary philosophy of language. The interest of his incisive and instructive book lies in the detail of his arguments. This is a book to be reckoned with.” – Alasdair MacIntyre, Professor of Philosophy Emeritus, University of Notre Dame, USA

“I find it fascinating and full of insights . . . this book is always provocative, insightful, and original.” – Martha Nussbaum, Department of Philosophy and Law School, University of Chicago, USA
