The Spock rule allows only objectively observable attributes of a koan to be relevant. Spock can't passively observe an obscured pyramid, so they don't exist. If a pyramid falls in the forest, and it gets covered up by a black one, does it exist? :) -----Original Message----- From: icehouse-bounces@xxxxxxxxxxxxxxxxxxxx [mailto:icehouse-bounces@xxxxxxxxxxxxxxxxxxxx] On Behalf Of Elliott C.

Schroedinger's Pyramid! Really, if I understand such things correctly, an obscured piece possibly exists, but in an indeterminate state expressed as a probability of existence. Only through observation can we collapse the quantum state, and until then it both exists and does not exist. Such philosophical conundra are one reason most people don't play Zendo with opaque pyramids. -- Elliott C.
