On Interpreting Keynes [PDF ebook] 
A Study in Reconciliation

There is discontent with how the textbooks have come to reinterpret Keynes but there is little communication between the most prominent schools of criticism. This book argues that this lack of dialogue is mistaken and damaging. A synthesis is possible as many of the arguments between them can be traced to simple misunderstadings and differences of emphasis.
