Human Behavior must follow the same natural laws ruling Life on Earth similar to the Force of Gravitation in the Universe. Therefore, all Natural or Physical Laws determine the behavior of matter on living individual organisms to react consciously or unconsciously, creating thought and reasoning transformed on intelligence in humans that determine the legitimate equilibrium of human moral laws and making possible the human behavior to eliminate or control the aggressiveness surging among humans once confronted with overpopulation, poverty, education or physical inequalities since the beginning of the evolution of the cooperative community through our present Societies... The author has selected his latest 8 books containing answers to why Civilizations all over the globe have disappeared in the dust of history, mostly due to human aggressiveness. Behavior is not only determined by feelings but also by knowledge, understanding and reason. So, let's teach every generation, thru Post-Secondary education, emphasizing also in Science and Technology, and positive results will be seeing after a few generations, that slowly but firmly will create a normal social behavior, saving the human species from extinction thru warfare with weapons of mass destruction, but instead allowing humans to reach its ultimate goal, outlined in the title of this book "FOR A PEACEFUL MANKIND".
