“Imagine you have a large glass jar. Next to it, you have a few large rocks, a small pile of marble-sized pebbles, and a pile of sand. If you put in the sand or pebbles first, what happens? You can’t fit the big rocks in. But if you add the big rocks, then the medium-sized pebbles, and only then the sand, it all fits.” In other words, the minutiae fit around the big things, but the big things don’t fit around the minutiae.
