Hi,
<<
But that ball never goes anywhere. I'd rather build a set of
gyroscopes inside the first two balls such that when the bottom one
rolls, the top one counter-rotates in exact response. Then give the
system a little nudge and it will roll, upright, along the path.
Sure, it's unstable in principle...but it moves.

That would be interesting. But is *inherent* instability in your belief set a possible human condition? (i.e. can a human mind maintain cognitive dissonance on a permanent basis?) Let's not loose ourselves in the metaphor!
