"[J]ust as I am not writing for those who feel confident that canons of appropriate constitutional construction may be convincingly derived from some neutral source, so I am also not writing for those who have convinced themselves that "anything goes" as long as it helps end what they see as injustice; that constitutional law is only a legitimating mask for what those in power can get away with; or that it is only a tame language in which those that would otherwise foment violent revolution can couch their demands in forms the regime might accept without losing face."
