Enantiodromia (Ancient Greek: ἐναντίος, romanized: enantios – "opposite" and δρόμος, dromos – "running course") is a principle introduced in the West by psychiatrist Carl Jung.

A central premise of the I Ching is that yang lines become yin when they have reached their extreme, and vice versa.
Jung himself wrote: "Old Heraclitus, who was indeed a very great sage, discovered the most marvellous of all psychological laws: the regulative function of opposites.
For example, it has been applied to the subject of the film The Lives of Others, to show how one devoted to a communist regime breaks through his loyalty and emerges a humanist.
