Might they also be interested that in Egypt, long-ago, in the shadow of the
Pyramids, folks not only understood this to be true, but were not content
with this knowledge. A way of thinking was developed that allowed them to
become satisfied that the truth of this observation "makes sense" - that we
should in fact *expect* it to be true.
What seems surprising - given a logical progression of thought - can be
found to be not surprising, really.
What is the lesson to be learned from that?
To me, it *is* the lesson.
