Carlyle's Forth Estate

In On Heroes and Hero Worship (1841), Thomas Carlyle writes:

"[T]urning now to the Government of men. Witenagemote, old Parliament, was a great thing. The affairs of the nation were there deliberated and decided; what we were to do as a nation. But does not, though the name Parliament subsists, the parliamentary debate go on now, everywhere and at all times, in a far more comprehensive way, out of Parliament altogether? Burke said there were Three Estates in Parliament; but, in the Reporters' Gallery yonder, there sat a Fourth Estate more important far than they all. It is not a figure of speech, or a witty saying; it is a literal fact,--very momentous to us in these times. Literature is our Parliament too. Printing, which comes necessarily out of Writing, I say often, is equivalent to Democracy: invent Writing, Democracy is inevitable. Writing brings Printing; brings universal everyday extempore Printing, as we see at present. Whoever can speak, speaking now to the whole nation, becomes a power, a branch of government, with inalienable weight in law-making, in all acts of authority. It matters not what rank he has, what revenues or garnitures. The requisite thing is, that he have a tongue which others will listen to; this and nothing more is requisite. The nation is governed by all that has tongue in the nation: Democracy is virtually there. Add only, that whatsoever power exists will have itself, by and by, organized; working secretly under bandages, obscurations, obstructions, it will never rest till it get to work free, unencumbered, visible to all. Democracy virtually extant will insist on becoming palpably extant"
