Philosopher Kevin Vallier of Bowling Green State University suggests that libertarians need to think more carefully about the complicated territory between church and state. A propertarian approach will not suffice, he argues, and yet neither the left nor the right offers genuinely liberal solutions to the problems of religion in public life. Vallier recommends a set of principles that are at once anti-establishmentarian — there will be no official church — and yet “constructive,” in that it welcomes religious interests and even religious arguments on questions of public policy.

Patrick J. Deneen argues that the boundaries of political discourse have moved leftward. As a result, so-called religious conservatives now stand in the place that classical liberals formerly occupied: All that they want is a simple religious liberty, with an acknowledgement of the Judeo-Christian character of the morals needed to sustain such liberty. Today’s so-called classical liberals have forgotten their own heritage, and they stand ready to align with secular progressives. Deneen charges that these progressives have as their object nothing less than the criminalization of Christian belief and expression. Those who value small government should therefore side with Christian conservatives.

Maggie Garrett takes some issue with the classification system outlined in Kevin Vallier’s lead essay; she does not recognize herself, for one, in Vallier’s portrait of secular progressives. She denies that she stands for secular establishmentarianism in particular, and she would not discount the opinions of people of faith. Yet to count as a valid reason in public policy, she believes that more is required than bare divine revelation; justifications must be given that carry the power to convince others. She would refuse the granting of religious exemptions to otherwise secular institutions, like businesses, that would deny services to same-sex couples or marriages. She defends the contraception mandate along similar lines.

Michael Shermer argues that science is producing better government, and that religion hasn’t been a help to it. In a liberal democracy, citizens can experiment with how they want to be governed. They can compare ideas and try out new ones. The American experiment, as it is often called, has been a success in many different ways. Meanwhile, expressions of religion in the public sphere are increasingly “obsolete.” This fact should be recognized; religion should retreat from public life just as it has from scientific inquiry, and for the same reasons.
