In Judaism Straight Up, Moshe Koppel explores the central differences between traditional societies - including traditional Judaism - and contemporary cosmopolitan ones. He explains everything you always wanted to know about the subtleties of Jewish morality, tradition, and belief, and how these have unfolded to beat cosmopolitanism at its own advancing cooperation, fairness, and freedom. Written with incisiveness and droll wit - and a scientific sensibility that draws on economics, game theory, and other disciplines - Judaism Straight Up reveals the secret of Jewish traditionalism's endurance. "Koppel's eggheaded pugilism is a think Platonic dialogue meets advanced Gemara class meets The Moscow Puzzles - all rendered accessible. The author's prose is crisp and confident, and laced with subtle and not-so-subtle humor.. His insights into the underlying mega-trends transforming contemporary human (not just Jewish) society are not only fascinating; they have the added advantage of being dead-on... Judaism Straight Up is the blueprint for where we should be headed." —Ze'ev Maghen, Jerusalem Post "[A]n accessible yet rigorous defense of a Judaism that is humane and authentic." —Rabbi David Wolpe
