'This is by far the best book on the young Marx that I have read since the pioneering studies of the 1960s and 1970s. In scholarly terms, it is incomparably better. I can only hope that the book will have the success it deserves not least because it has upgraded the level of scholarship and intellectual nuance that future discussions of Marx will require, in particular the need to get to grips in detail with the political context through which Marx's early writings emerged.'
