Fences

"Don't ever take a fence down until you know the reason why it was put up." - G. K. Chesterton

"Chesterton went on to explain why this principle holds true, writing that fences don’t grow out of the ground, nor do people build them in their sleep or during a fit of madness. He explained that fences are built by people who carefully planned them out and “had some reason for thinking [the fence] would be a good thing for somebody.” Until we establish that reason, we have no business taking an ax to it. The reason might not be a good or relevant one; we just need to be aware of what the reason is. Otherwise, we may end up with unintended consequences: second-and third-order effects we don’t want, spreading like ripples on a pond and causing damage for years." - ronaldvr of Reddit
