Unfortunately, history happened. Rules for utopia can deal with individual crimes—the mugger and the killer and the vandal—but they stumble in the face of societywide injustice. They tell us the state shouldn’t sanction the brutal enslavement or humiliating legal subordination of a people; they have less to say about what to do once we have. They tell us to respect the sanctity of the property rights that would arise as free people tamed the wilderness in John Locke’s state of nature. They have less to say about the sanctity of property built on generations of slave sweat and blood.
