Jung's fascination with the third and the fourth

The book explores Jung's obsession with the third and the fourth, examining the complex relationship between Plato and Jung. It delves into Jung's reading of Plato's Tameis and his interpretation of the doctrine of the Trinity. The book also explores the role of the Tameis in cosmology, the third and the fourth in alchemy, and the concept of synchronicity. Through these investigations, the author raises the question, 'Why must the third become the fourth?' and explores the theme of totality and the self in Jungian psychology.
