I believe every graduate student of economics should read this book. It is not that I support everything in this book, and one Amazon review has it right that Professor Rubinstein is trying “to challenge the entire discipline of economics, to draft sweeping indictments against it.” However it grapples with the big questions, and shows a scholar’s inner debate with himself, and teaches that you are not alone in doubting and questioning what you do.
