Having two minds, we have discovered, does not make us twice as clever. It merely ensures that when something goes terribly wrong, we have someone nearby to argue with about whose fault it is. In this case, the debate was complicated by the fact that we were dangling upside down from a rope in a courtyard that had been, until moments before, enjoying a perfectly respectable level of order. Several uniformed individuals had gathered beneath us and were gesturing in that particular way people do when confronted with something they strongly suspect is both illegal and deeply idiotic. We attempted to explain that the current arrangement was temporary, theoretical, and possibly even educational, though the blood rushing to our head made the lecture less persuasive than we would have liked. We would like to clarify that the rope situation was not our fault. Well, not entirely our fault. In our defense, the sign had said “Do Not Touch the Cognitive Anchor,” which any reasonable person would interpret as a challenge.
