Group organization,” said the late Robert Luce, momentarily dropping his usually cautious phrasing, “is one of the perils of the times.”1 The scholarly Yankee legislator’s opinion has been echoed and re-echoed, sometimes in qualified and sometimes in categorical terms, by an impressive number of journalists, academicians, and politicians.
