"Owen's Moral Physiology; or, A Brief and Plain Treatise on the Population Question" by Ralph Glover, M.D. is a scientific publication written in the mid-19th century. This treatise tackles the delicate issues surrounding human reproduction, population control, and social morality, focusing on how understanding our physiological nature can influence societal norms and the well-being of families. The text argues for the necessity of controlled reproduction and the benefits that can arise from educated discussions regarding the reproductive instinct. The opening of the work sets the stage for a comprehensive exploration of moral physiology, beginning with an introduction to the fundamental reproductive instincts and their implications for personal and societal well-being. It discusses the concept of utility as it relates to family planning and population control, emphasizing the desire for knowledge over ignorance. Glover introduces the idea of a moral restraint on reproduction, suggesting that such control is essential for securing happiness and reducing societal issues like poverty and intemperance. He positions his discussion as a response to prevailing misconceptions about the reproductive instinct, advocating for clear communication and understanding to prevent the deleterious effects of unrestrained procreation on both individuals and society at large.
