A tremendous economy of description is one of the defining and most surprising features of modern science; it is not a priori obvious that a small collection of fundamental laws should be capable of describing the limitless complexity of objects that populate our universe, and yet this is what we have discovered over the last few centuries. Perhaps a universe regular enough to permit the existence of natural objects as complex as the human brain must be governed by a simple set of laws, but since we do not yet understand the origin of the laws, we do not know.
