Douthat is right in his response to Yglesias; he might have added, too, that “few philosophers” is one of those academic tricks whereby all the members of the guild who would upset an elite consensus are excluded from the set by virtue of either their perceived religiosity (thus they don’t count) or their perceived marginal views (ditto)—hence, a perfectly circular “consensus” achieved solely through the explicit operation of ruling out dissenters on principle, the principle being that they dissent from the consensus, which consensus is arrived at only (again) through not allowing those who disagree to count.
