"THE really courageous man is he who defies tyrannies young as the morning and superstitions fresh as the first flowers. The only true free-thinker is he whose intellect is as much free from the future as from the past. He cares as little for what will be as for what has been; he cares only for what ought to be. And for my present purpose I specially insist on this abstract independence. If I am to discuss what is wrong, one of the first things that are wrong is this: the deep and silent modern assumption that past things have become impossible. There is one metaphor of which the moderns are very fond; they are always saying, "You can't put the clock back." The simple and obvious answer is "You can." A clock, being a piece of human construction, can be restored by the human finger to any figure or hour. In the same way society, being a piece of human construction, can be reconstructed upon any plan that has ever existed."
~G.K. Chesterton: What's Wrong With the World, Part One, Chap. IV.
