A disciple came to a temple to speak with a master ontologist.
“Master,” the disciple said, “teach me how to describe all existence!”

The master handed the disciple a pebble. “First, start by describing
this small stone.” The disciple went away and sat under a bridge by a
stream. For six days and nights he struggled to create a taxonomy for
the pebble. On the seventh day, he returned to the temple.

“Master,” the disciple said, “I have devised the perfect taxonomy for
this small stone.” He unrolled an entire scroll at the master’s feet,
covered on both sides with arcane markings, graphs, and code.

The master then struck the disciple on the head with a stick. The
disciple was then enlightened.
