Jeffrey Katz explores the age-old question of how to live a fulfilling life in his book, 'Rules to Live By: Maimonides' Guide to a Wonderful Life.' Katz asserts that the answers to this question are not new, but have been available for centuries through the teachings of Maimonides. The article delves into whether readers of Katz's work can genuinely achieve a better life by following these timeless principles. It also touches on the idea that extremism may stem from a lack of embracing such enduring wisdom.
