Sooner or later, everything turns into its opposite.

Carl Jung, Two Essays (1928), I, ch. V 'The Personal Unconscious and the Super-personal or Collective Unconscious'

What it means

Jung borrowed this law from Heraclitus and made it a rule of the mind. Push any attitude to its extreme and it flips: the strict turn wild, the rational turn irrational. Balance is the only way to avoid the swing.

The source

"Sooner or later, everything turns into its opposite." Carl Jung said it in Two Essays (1928), I, ch. V 'The Personal Unconscious and the Super-personal or Collective Unconscious'. Translated by H. G. and C. F. Baynes, 1928.

"He called it enantiodromia (a running contrary ways), by which he meant that everything tends sooner or later to go over into its opposite."

Who said it

Carl Jung (1875–1961). Swiss psychiatrist who broke with Freud and founded analytical psychology. He mapped the persona, the shadow, the collective unconscious and the lifelong work of becoming yourself, which he called individuation. Our lines come only from his writings published before 1931, in our own translations from the German or in English translations of the time.
