The moment you step into a world of facts, you step into a world of limits. You can free things from alien or accidental laws, but not from the laws of their own nature. You may, if you like, free a tiger from his bars; but do not free him from his stripes. Do not free a camel from the burden of his hump: you may be freeing him from being a camel. G. K. Chesterton
