History doesn't repeat itself...

A contemplation upon a disturbing waking dream, recalling the passing of two twins who were friends.

Quoth George Santayana,

Those who do not remember the past are condemned to repeat it.

But George also said,

History is a pack of lies about events that never happened told by people who weren't there.

Both comprise a subtle truth, for history never truly repeats itself, it just exhibits emergence of self-similar event patterns across time and space.

History is fractal.
