This book is the extended outcome of an argument between the author and his Rabbi. The latter insisted that the morals in the Talmud represented the best basis of human behavior while the author argued that no document written five thousand years ago could reflect the knowledge acquired in that 5000 years, particularly the scientific advancements of the last 300 years. After several inconclusive continuations of these different viewpoints, Rabbi Galpert suggested I write him a sermon reflecting my viewpoints. "But don't make it more than thirty minutes." Since my education was that of a mechanical, and later a nuclear engineer, I reviewed many modern books on evolution, psychology, anthropology and sociobiology. Then one night I conceived the following approach: A basic assumption: The most important thing in life is life itself. And the axiom: What our ancestors did that resulted in our being here, were the right things for us to do. So all I had to do was list the things they must have done so that I am here. Skipping the extensive definitions of terms used, the absence of absolutes, the scientific method, but including the origin and the strong role of religion, I came up with the following primordial laws (PLs). Do what is necessary to stay alive. Consenting safe sexual activity is healthy, but any progeny must be nurtured until they are able to be self supporting. Cooperate with and do no harm to others. Do your own thing, but remember the above. Value intelligence above strength and speed. Speak up and give others the benefit of your thoughts. Adapt to changes in physical and societal environments. You are free to go where the grass is greener. The things you make by your own efforts are yours. Public property is for everyone's benefit and must not be damaged. All of the above PLs are treated in detail in the book. We also look to the future. The method of applying hierarchical order of these PLs is illustrated. The treatment of exceptions shows the difference between scientific and religious considerations. The reader is encouraged to his/her reaction to this book with additions, changes and suggestions.
