Today, scientists are using CRISPR/Cas9 and other molecular editing tools to alter human gametes and embryos, a practice known as human germline modification. In the near future, these efforts may lead to the birth of children with better health, improved memories, and extended lifespans. However, critics claim that human germline modification exceeds divine and natural boundaries, transforms reproduction into manufacture, and yields apocalyptic outcomes such as the collapse of democracy. Enhanced Beings: Human Germline Modification and the Law analyzes and critiques these objections on both biological and political grounds. Professor Kerry Lynn Macintosh discusses the hidden psychology behind the objections, and describes the laws that affect this new technology. Provocative and timely, Enhanced Beings argues that bans on human germline modification pose a threat to scientists and science, parents, children, foreigners, and society.

Since Dolly the sheep was born, controversy has swirled around the technology of cloning. We recoil at the prospect of human copies, manufactured men and women, nefarious impersonators and resurrections of the dead. Such reactions have serious legal consequences: lawmakers have banned stem cell research along with the cloning of babies. But what if our minds have been playing tricks on us? What if everything we thought we knew about human cloning is rooted in intuition rather than fact? Human Cloning: Four Fallacies and Their Legal Consequences is a rollicking ride through science, psychology, and the law. Drawing on sources ranging from science fiction films to the Congressional Record, this book unmasks the role that psychological essentialism has played in bringing about cloning bans. It explains how hidden intuitions have caused conservatives and liberals to act contrary to their own most cherished ideals and values.

Many people think human reproductive cloning should be a crime-some states have even outlawed it and Congress is working to enact a national ban. However, if reproductive cloning soon becomes a reality, it will be impossible to prevent infertile couples and others from choosing the technology, even if they have to break the law. While most books on cloning cover the advantages and disadvantages of cloning technology, Illegal Beings describes the pros and cons of laws against human reproductive cloning. Kerry Lynn Macintosh, an attorney with expertise in the area of law and technology, argues that the most common objections to cloning are false or exaggerated, inspiring laws that stigmatize human clones as subhuman and unworthy of existence. She applies the same reasoning that was used to invalidate racial segregation to show how anti-cloning laws, by reinforcing negative stereotypes, deprive human clones of their equal protection rights under the law. Her book creates a new topic within constitutional law: existential segregation, or the practice of discriminating by preventing the existence of a disfavored group or class. This comprehensive and novel work looks at how anti-cloning laws will hurt human clones in a fresh perspective on this controversial subject. Kerry Lynn Macintosh is a member of the Law and Technology faculty at Santa Clara University School of Law. She is the author of papers, articles, and book chapters on the law and technology and has contributed to the Harvard Journal of Law and Technology, Boston University Journal of Science and Technology Law, and Berkeley Technology Law Journal.
