In what context has paradox been used in this sentence? ''all animals are equal, but some are more equal than others".

Superiority in disguise

Explanation:

 The sentence "All animal are equal, but some are more equal than others" is from the novel Animal Farm, by George Orwell, in which one of the animals laws ('All animals are equal.") was altered, now  having another or no meaning. The paradox (contradictory ideas) in the sentence is that by saying "equal/more equal", though it is a nonsense, it hides the advantages some have over others in a society with supposed social equality.
