The main dangers in this life are the people who want to change everything... or nothing.

The remark frames political and social life as threatened by two opposing forms of extremism: the zealot who insists on sweeping transformation regardless of cost, and the reactionary who resists any change even when conditions demand it. By pairing these impulses, the line argues for prudence, incremental reform, and attention to consequences—suggesting that stability and progress both become dangerous when pursued as absolutes. Attributed to Nancy Astor, a figure associated with parliamentary politics and sharp epigrams, the quote reads like a caution against ideological purity and a defense of practical compromise in governance and personal conduct.
