This book offers a rational explanation of the anomalies of human behavior. It was inspired by a study of the works of Sade, which cover all aspects of human experience - the inner experience of the individual as well as the experience of the individual relative to other individuals, to groups and to the universe as a whole.
Part I summarizes, with specific references and quotations, all that Sade actually said about these aspects of human experience including his futile attempts, in the light of the religious philosophical, and scientific concepts of his time, to explain the anomalies he observed and described - the misfortunes of virtue and the prosperity of vice; murder; suicide; the connection of crime, cruelty, perversity, and sacrilege with sex; prostitution; adultery; incest; homosexuality; pederasty; despotism; war; anarchy; revolution, etc.
In Part II, Lorna Berman, starting with an assumption about he beginnings of the universe implicit in the work of Sade, and using only logic and simple arithmetic, expounds a theory about he operation of the universe - the formation of entities, the beginnings of life, propagation, the possibility of everlasting life, and the formation of groups - with a view to explaining the human anomalies portrayed by Sade.
In Part III, L. Berman explains the anomalies of human behavior in the light of her own theory (outlined in Part II), which reflects rather 20th century philosophical, religious and scientific sensitivities. The phenomena described in Part I are used as examples, since Sade's work constitutes one of the broadest descriptions of human nature ever written.
