"The issues of human violence and human pleasure are pivotal to any theory—scientific or religious—of moral behavior. Violence and pleasure are reciprocally related, that is, the presence of one inhibits the other, and certain critical early sensory experiences during the formative periods of development provide the neurobiological substrate and properties for either violence-seeking or pleasure-seeking behaviors."

“The effects of "maternal-social" deprivation, institutionalization, hospitalization, and of parental abuse, neglect, and indifference, upon infant and child development have been well described by many investigators.”

“Body pleasure is very different from promiscuity, which reflects a basic inability to experience pleasure. If a sexual relationship is not pleasurable, the individual looks for another partner. ...Affectionately shared physical pleasure... tends to stabalize a relationship and eliminate the search.”

“Modern technologies of warfare have made it possible for an individual or nation to bring total destruction to large segments of our population. And the greatest threat comes from those nations which have the most depriving environments for their children and which are the most repressive of sexual affection and female sexuality. We will have the most to fear when these nations acquire the weapons of modern warfare. Tragically, this has already begun.”

“Cultural anthropologists have gathered exactly the data required to examine this hypothesis for human societies—and their findings are conveniently arranged in R. B. Textor's A Cross Cultural Summary.”

“Certain sensory experiences during the formative periods of development will create a neuropsychological predisposition for either violence-seeking or pleasure-seeking behaviors later in life.”

“Stimulation of brain pleasure centers can eliminate feelings of rage, fear, and depression.”
