THE DIFFERENCE BETWEEN REVOLUTION and defiance is the difference between an overthrow of the existing order and one person’s shaken fist. When the former isn’t possible, you still have to hold on to the latter, if only so as to remember you’re human. Defiance is the insistence on individual power confronting overwhelming force that it cannot undo. You know you cannot strike the colossus. But you can defy it with words or signs. In the assertion that you can fight a superior power, the declaration that you will, this absurd overstatement gains dignity by exposing you, however uselessly, to risk. Unable to stop it in its tracks, you dare the crushing power to begin its devastation with you.
