The film thematizes brutal and irrational authority. Writers and scholars have argued the film reflects a subconscious need in German society for a tyrant, and is an example of Germany's obedience to authority and unwillingness to rebel against deranged authority. Some critics have interpreted Caligari as representing the German war government, with Cesare symbolic of the common man conditioned, like soldiers, to kill. Other themes of the film include the destabilized contrast between insanity and sanity, the subjective perception of reality, and the duality of human nature.
