Twenty-five hundred years ago, Pythagoras taught that the simple counting numbers are the basic building blocks of reality. A century and a half later, Plato argued that the world we live in is but a poor copy of the world of
ideas. Neither realized that their
numbers and
ideas might also be the most basic components of the human psych:
archetypes. This book traces the modern evolution of this idea from the Renaissance to the 20th century, leading up to the archetypal hypothesis of psychologist C. G. Jung, and the mirroring of mathematical ideas of Kurt Gödel.
