There is ample reason to disagree with originalism as a legal philosophy. Should a 21st century society really interpret its Constitution by the standards of 1787 — an era before the introduction of semi-automatic weaponry, steam power, penicillin, automobiles, trains, electric lights and indoor plumbing? In some ways, though, that’s a pointless debate at the moment. With originalists holding six of the Supreme Court’s nine seats, we’re all living in an originalist world.
The functional problem with originalism is that it requires a very, very firm grasp of history — a grasp that none of the nine justices, and certainly few of their 20-something law clerks, freshly minted from J.D. programs, possess.
It’s difficult to become an expert in American political, legal or social history. It’s quite easy, though, to cherry-pick historical examples that prop up an end in search of a rationale — which is precisely what the Supreme Court majority did this week, twice.
