Free Market Fairness (Princeton University Press, 2012)

Can libertarians care about social justice? In Free Market Fairness, John Tomasi argues that they can and should. Drawing simultaneously on moral insights from defenders of economic liberty such as F. A. Hayek and advocates of social justice such as John Rawls, Tomasi presents a new theory of liberal justice. This theory, free market fairness, is committed to both limited government and the material betterment of the poor.

Unlike traditional libertarians, Tomasi argues that property rights are best defended not in terms of self-ownership or economic efficiency but as requirements of democratic legitimacy. At the same time, he encourages egalitarians concerned about social justice to listen more sympathetically to the claims ordinary citizens make about the importance of private economic liberty in their daily lives. In place of the familiar social democratic interpretations of social justice, Tomasi offers a "market democratic" conception of social justice: free market fairness. Tomasi argues that free market fairness, with its twin commitment to economic liberty and a fair distribution of goods and opportunities, is a morally superior account of liberal justice. Free market fairness is also a distinctively American ideal. It extends the notion, prominent in America's founding period, that protection of property and promotion of real opportunity are indivisible goals. Indeed, according to Tomasi, free market fairness is social justice, American style.

Liberalism Beyond Justice: Citizens, Society and the Boundaries of Political Theory (Princeton University Press, 2001)

Liberal regimes shape the ethical outlooks of their citizens, relentlessly influencing their most personal commitments over time. On such issues as abortion, homosexuality, and women's rights, many religious Americans feel pulled between their personal beliefs and their need, as good citizens, to support individual rights. These circumstances, argues John Tomasi, raise new and pressing questions: Is liberalism as successful as it hopes in avoiding the imposition of a single ethical doctrine on all of society? If liberals cannot prevent the spillover of public values into nonpublic domains, how accommodating of diversity can a liberal regime actually be? To what degree can a liberal society be a home even to the people whose viewpoints it was formally designed to include?

To meet these questions, Tomasi argues, the boundaries of political liberal theorizing must be redrawn. Political liberalism involves more than an account of justified state coercion and the norms of democratic deliberation. Political liberalism also implies a distinctive account of nonpublic social life, one in which successful human lives must be built across the interface of personal and public values. Tomasi proposes a theory of liberal nonpublic life. To live up to their own deepest commitments to toleration and mutual respect, liberals, he insists, must now rethink their conceptions of social justice, civic education, and citizenship itself. The result is a fresh look at liberal theory and what it means for a liberal society to function well.

Current Projects

Professor Tomasi is currently at work on a book that is co-authored with Matt Zwolinski, titled A Brief  History of Libertarianism (under contract with Princeton University Press) in addition to a new chapter for the Spanish translation of his 2012 book, Free Market Fairness, in which he explores the logistics of applying his theory of market democracy, central to the book, at the policy level in Chile.
