This book is a reworking of Brains and Careers, slimmed down, and the Four Roles emphasized even more. This will be the last word on normal human action by Dr. Keirsey. This the final culmination of his study of human behavior, having used his 89 years of life experience in discerning differing preferences of individuals on their inborn natures and to act on those preferences in light of the surrounding circumstances.
