The radicals are really always saying the same thing. They do not change; everybody else changes. They are accused of the most incompatible crimes, of egoism and mania for power, indifference to the fate of their own cause, fanaticism, triviality, want of humor, buffoonery and irreverence. But they sound a certain note. Hence the great practical power of consistent radicals. To all appearance nobody follows them, yet everyone believes them. They hold a tuning-fork and sound A, and everybody knows it really is A, though the time-honored pitch is G flat. The community cannot get that A out of its head. Nothing can prevent an upward tendency in the popular tone so long as the real A is kept sounding.
