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.
