Samuel L. Clemens, using the pseudonym Mark Twain, publishes A Connecticut Yankee in King Arthur’s Court, a satirical criticism of predatory social institutions.  In chapter 11, paragraph 4 he writes:

       The citizen who thinks he sees that the commonwealth’s political clothes are worn out, and yet holds his peace and does not agitate for a new suit, is disloyal, he is a traitor.  That he may be the only one who thinks he sees this decay, does not excuse him: it is his duty to agitate anyway, and it is the duty of others to vote him down if they do not see the matter as he does.
