What it argues
Justice: What's the Right Thing to Do? grew out of Michael Sandel's famous introductory ethics course at Harvard, which became one of the most watched lecture series in university history. The book is a guided tour of the three major frameworks in moral and political philosophy — utilitarianism, libertarianism, and virtue ethics — tested against real moral dilemmas from affirmative action and same-sex marriage to financial bailouts and wartime service.
Sandel begins with utilitarianism, the view that the right action maximizes overall welfare. He shows how powerful the framework is — and where it breaks down. Torturing one person to save five hundred raises the utilitarian calculus but outrages the intuition that some individuals have rights that can't be bargained away. He then covers Kant's deontological ethics, which grounds rights in the idea that persons must never be treated merely as means, and examines Rawls's theory of justice behind the veil of ignorance as a modern Kantian alternative.
What it gets right
- 1.
Three main frameworks structure moral philosophy: utilitarianism (maximize welfare), deontology (respect rights regardless of outcomes), and virtue ethics (ask what the good life and a good society require).
- 2.
Utilitarianism's chief weakness is that it allows sacrificing individuals for aggregate gain. Its chief strength is that it takes everyone's welfare seriously.
- 3.
Kant argues morality is grounded in reason and respect for persons as ends in themselves, never merely means. This rules out using people instrumentally even for good outcomes.
