Enantiodromia

Enantiodromia (Greek: ἐνάντιος, enantios, opposite and δρόμος, dromos, running course) is a principle introduced by psychiatrist Carl Jung that the superabundance of any force inevitably produces its opposite. It is similar to the principle of equilibrium in the natural world, in that any extreme is opposed by the system in order to restore balance. When things get to their extreme, they turn into their opposite. However, in Jungian terms, a thing psychically transmogrifies into its shadow opposite, in the repression of psychic forces that are thereby cathected into something powerful and threatening. This can be anticipated as well in the principles of traditional Chinese religion – as in Taoism and yin-yang.
