Probably many that aren't based on set theory.

Set theory by its very nature does not possess a concept of order. If I'm right, it doesn't possess a concept of uniqueness either, does it? (In that uniqueness is a requirement and duplicates are impossible, therefore uniqueness is a "meaningless" concept as there is nothing to contrast it with...)
