A growing number of political philosophers favor a view called liberal perfectionism. According to this view, liberal political morality is characterized by a commitment to helping individuals lead autonomous lives and making other valuable choices. In this book Jonathan Quong rejects this widely held view and offers an alternative account of liberal political morality. Quong argues that the liberal state should not be engaged in determining what constitutes a valuable or worthwhile life nor trying to make sure that individuals live up to this ideal. Instead, it should remain neutral on the issue of the good life, and restrict itself to establishing the fair terms within which individuals can pursue their own beliefs about what gives value to their lives. Liberalism without Perfection thus defends a position known as political liberalism.
In the first part of the book, Quong subjects the liberal perfectionist position to critical scrutiny, advancing three major objections that raise serious doubts about the liberal perfectionist position with regard to autonomy, paternalism, and political legitimacy. In the second part of the book, Quong presents and defends a distinctive version of political liberalism. In particular, he clarifies and develops political liberalism's central thesis: that political principles, in order to be legitimate, must be publicly justifiable to reasonable people. Drawing on the work of John Rawls, Liberalism without Perfection offers its own interpretation of this idea, and rebuts some of the main objections that have been pressed against it. In doing so, it provides novel arguments regarding the nature of an overlapping consensus, the structure of political justification, the idea of public reason, and the status of unreasonable persons.

When is it morally permissible to engage in self-defense or the defense of others? Jonathan Quong defends a variety of novel ideas in this book about the morality of defensive force, providing an original philosophical account of the central moral principles that should regulate its use. We cannot understand the morality of defensive force, he reasons, until we ask and answer deeper questions about how the use of defensive force fits with a more general account of justice and moral rights. In developing this stance, Quong presents new views on liability, proportionality, and necessity. He argues that self-defense can sometimes be justified on the basis of an agent-relative prerogative to give greater weight to one's own life and interests, contrary to the dominant view in the literature. Additionally Quong develops a novel conception of individual rights against harm. Unlike some, who believe that our rights against harm are fact-relative, he argues that our rights against being harmed by others must, in certain respects, be sensitive to the evidence that others can reasonably be expected to possess. The book concludes with Quong's extended defense of the means principle, a principle that prohibits harmfully using other persons' bodies or other rightful property unless those persons are duty bound to permit this use or have otherwise waived their claims against such use.
