Written in 1949, this study is an effort to apply the methods of science to a study of the basic causes of human conflict. Using a research from over thirty years and addressed to the layman as well as the scientist it reports findings and formulations that emerged from investigations into man's inter-rational behaviour. Describing the inception and development of objective methods for evaluating and controlling human conflict. This study is based on the history of the author's and Clarence Shield's association with the The Lifwynn Foundation and work on the history of phylobiology. It discusses the investigations around: what man is overtly is not what man is basically; that the externals of man are not man and exploring human relations as psychosocial and not biological. Looking at the issue basic to human motivation and behaviour, the problem of self, the investigation comes to the conclusion that phylobiology is the application of scientific method to the field of human relations and this report presents an account of the enquiry into disorders of human behaviour.
