I also want to reject both the naive proposition that we are prisoners of our pasts and the pernicious suggestion that history is whatever we make of it. History is the fruit of power, but power itself is never so transparent that its analysis becomes superfluous. The ultimate mark of power may be its invisibility; the ultimate challenge, the exposition of its roots.
