Does the book rely on a significant basis of science and evidence to reach its conclusions? Yes. The book relies on over a hundred scientific papers, experts, legal documents, verifiable media reports, and case studies that demonstrate the overwhelming biological and social propensity for natural aggression and violence to become worse if humans do not actively undertake rational strategies to reduce its effect on a society.

Does the book challenge some historical and modern ideological arguments using a strong basis of facts? Yes. The book inspects the historical and modern ideological arguments that several people and groups have made that do not conform to the historical record. It delves into the human mind's frequent desire to perceive what it desires to be true despite what might be true and that our rational faculties can be frequently manipulated by our emotions and lower brain.

Is there new and important evidence and data in the book that is useful to every reader? Yes. It provides context and wider scope of humanity's past to explain why violence has been our eternal companion and the necessary part it has played in our development. The book presents data, experts, and commentary supporting all that is required to be violent is feeling wronged despite not being targeted with aggression. The book confronts the call of some to reduce useful competition while permitting more self-destructive behaviors that create emotionally detached people.

How is this book different from other books available that discuss complex and controversial subjects? The book's contentions are not based upon political or ideological lines and it sets aside any religious, national, or special interest group credos. The facts and arguments presented rely upon not just the better nature of humanity but also upon its flaws and repeated actions over the course of hundreds of thousands of years prior any modern revisions. Further, the book inspects the natural world similarities that humanity shares with its fellow creatures and pairs this with substantial evidence of where our path has led and might progress if current trends persist.    

Is this book for everyone? No. It is not intended for children, the easily offended, or anyone that does not support a wide range of verifiable science, rational thought, and substantial evidence that often violates ideological beliefs. The book discusses matters of grave importance that are not conducive to safe conversations or ideas without extensive consideration of the violent behaviors and trends of most past and modern humans.
