Just to prove we're going in circles, this is where I mention the really great (even for the generally crappier later seasons) Red Dwarf episode, "Cassandra," where a future-telling computer leads to a woman saying "I can't believe I'm being seduced by a predestination theory."

Or "I am your density". Which, curiously, ties in quite well with both "predestination" and "red dwarf".
Wheels within wheels. ;o)
