"WE often read nowadays of the valor or audacity with which some rebel attacks a hoary tyranny or an antiquated superstition. There is not really any courage at all in attacking hoary or antiquated things, any more than in offering to fight one's grandmother. 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.
