Exploring Human Thought

My work is a new approach to understanding how we think and, therefore, how we behave. My analysis of the human thinking process starts with the earliest single-celled creatures, which have no equipment for thinking, and traces its evolution to modern people. Although the human brain is indeed a wondrous instrument, it evolved to serve the simpler needs of our ancestors in a much less complex world. As a result, humans have developed eight important types of errors in thinking because of shortcomings in our mental equipment to handle its new workload. An understanding of how the brain really works will help you reduce these errors and therefore, achieve greater success and happiness.

The Human Thinking Process - A Hypothesis in Evolutionary Neuropsychology

This material is a successor to Think Better, Feel Better, published in 1990 by Libra Publishers. That book started with my identification of eight common errors in the human thinking process. These observations led me to try to find a mechanism that could account for them. The objective of that book was to show the reader how to avoid these errors in thinking in order to feel better. The present effort concentrates instead on identifying the mechanisms underlying the thinking process. March, 2005 Click here to read this paper. (674 KB)

The Evolution of Human Behavior

This book describes the effect of the human thinking mechanism on the formation of cooperative groups, which was the beginning of human social behavior. We continue to behave in the same way our ancestors did in a much less complex world so that some of our behavior is no longer appropriate. Understanding this process will help you achieve greater social acceptance. This book also describes the mechanism for human communication to help improve both your transmission and reception.
