Richard Dagger purports to solve the problem of political obligation and the problem of punishment simultaneously, by employing the principle of fair play. Notwithstanding the valuable contribution his book makes to the philosophical debate, I argue that Dagger does not defeat long-standing objections faced by fair play-based justifications of the duty to obey the law and of state punishment.

理查德·达格（Richard Dagger）的评论：公平竞争：政治义务与惩罚问题

理查德·达格（Richard Dagger）主张通过运用公平竞争原则同时解决政治义务和惩罚问题。尽管他的书对哲学辩论做出了宝贵贡献，但我认为达格并没有克服长期存在的反对意见，这些反对意见是基于公平竞争的服从法律和国家惩罚义务的正当理由所面临的。
