The October, 2011 issue of Cato Unbound tackles some of the foundational questions of political theory: how do we recognize justice? If it's not utopia, is it still good enough to command our respect? Or allegiance? How do we know? Who are the members of the political community? How are they chosen? What counts as a "reason" for political action?
If all of this sounds abstract, rest assured that lead essayist Gerald Gaus is both lucid and engaging. He writes:
Liberalism’s founding insight was the recognition in the sixteenth and seventeenth centuries that controversial religious truths could not be the basis of coercive laws and public policies. The task is now to apply this insight to philosophizing about justice itself. This is an extraordinarily difficult lesson for many. Can it really be that I should not endeavor to ensure that my society conforms to my “knowledge” of justice? (Compare: can it really be that my “knowledge” of God’s will should not structure the social order?)
Gaus argues for a "range of justice"—a range of theories that, while perhaps not perfect by anyone's standards, are still close enough to demand our respect, especially given the large benefits that come from freely engaged social cooperation.
Discussing with him this month are a panel of three other prominent social theorists. Richard Arneson argues that we tolerate one another not because we're all pretty close to rational (clearly a lot of us aren't!)—but because intolerance breeds atrocity. Eric Mack argues that classical liberalism is no mere contending sect; it is the right approach to politics, because it offers the greatest leeway for individuals to choose their own ends in life. And Peter J. Boettke argues that any social system that neglects private property will fail to produce a cooperative society in any sense; without market exchange, individuals will fall into strife over scarce resources.
Obviously I won't be able to do justice to their arguments here, so please do check out Cato Unbound, where discussion will continue through the end of the month.
