Vivisection

Albert Leffingwell

"Vivisection" by Albert Leffingwell, M.D. is a scientific publication written in the late 19th century. The book discusses the controversial practice of vivisection—performing experiments on live animals—debating its ethical implications and utility in medical education and research. It seeks to address the moral dilemmas associated with such experiments while evaluating the actual benefits they provide to the field of medicine. In the book, Leffingwell presents a critical examination of vivisection, emphasizing the often severe pain inflicted on animals during these procedures. He articulates the argument that many vivisection practices do not yield significant results that justify the suffering caused, pointing out that while some physiological knowledge has been gained, it has not led to substantial advancements in therapeutics or the treatment of human disease. Addressing the opposition between scientific advancement and moral responsibility, Leffingwell advocates for greater oversight and restrictions on vivisection, particularly in educational settings, and calls for a re-evaluation of the practices that may desensitize medical students to suffering. Through a blend of personal observations, statistics, and appeals to ethical considerations, he argues for a more humane approach to scientific experimentation.
