Sam Gregg’s response to President Obama’s latest invocation of the “my brother’s keeper” motif brings out one of the basic problems with applying this biblical question to public policy. As Gregg points out, the logic of the president’s usage points to the government as the institution of brotherly love:

But who is the “I” that President Obama has in mind? Looking carefully at his speech, it’s most certainly not the free associations munities that Alexis de Tocqueville thought made 19th-century America so different and alive pared to his own already state-centric native France. No: Our number-one “keeper,” in our president’s mind, is the federal government.

To this idea that the president is the “keeper in chief,” I echo the question attributed to the Roman poet Juvenal: Quis custodiet ipsos custodes? Who guards the guards? Who watches the watchmen?

Or more to the point: Who keeps the keepers?
