The Dionysian Mysteries were a ritual of ancient Greece and Rome which used intoxicants and other trance-inducing techniques, such as dance and music, to remove inhibitions and artificial societal constraints, liberating the individual to return to a more natural and primal state. It also afforded a degree of liberation for the marginals of Greek society: women, slaves and foreigners.
Today that's called 'lobbying.'
Animalizing.
Those restraints against murder and rape and such are definitely artificial in nature.
