We assume, for ourselves, that we are capable of original thought. But the most creative things we have done have always been variations of existing work.
Lord of the Rings is a re-working of the Catholic faith into secular symbolism, mixed in with Norse myths and political commentary on socialism.

Unless I'm missing some past variation, wouldn't the above consist of original thought? My motto: Who Am I, If Not My Remote.
