Notwithstanding the absence of a historical basis for this theory of rigid separation, the wall idea might well have served as a useful albeit misguided analytical concept, had it led this Court to unified and principled results in Establishment Clause cases. The opposite, unfortunately, has been true; in the 38 years since Everson our Establishment Clause cases have been neither principled nor unified. Our recent opinions, many of them hopelessly divided pluralities,(6) have with embarrassing candor conceded that the "wall of separation" is merely a "blurred, indistinct, and variable barrier," which "is not wholly accurate" and can only be "dimly perceived." But no amount of repetition of historical errors in judicial opinions can make the errors true. The "wall of separation between church and State" is a metaphor based on bad history, a metaphor which has proved useless as a guide to judging. It should be frankly and explicitly abandoned.
Excellent! Thanks so much, Gawain. Bookmarked.
