'... a masterpiece ... long overdue' Professor Judy Sebba, University of Sussex and member of 2008 RAE panel for Education "This is an exceptional book - and one that should be essential reading for anyone seriously thinking about educational practice - for two reasons. First, it is one of the few books on thinking about education which is written with the wit and humour which makes compulsive reading. Second, the approach to theory (or thinking systematically, philosophically and evidentially) is through the author's own attempt to understand what appears to many as a mystery. In this personal journey, the author provides a comprehensive and critical review of different theoretical positions." Professor Richard Pring, University of Oxford
