“Is He Still Human? Are You?” Young Adult Science Fiction In The Post Human Age ”researcher Elaine Ostry analyzes science fiction texts, written for young adults, which deal with the tenets of our new biotechnology age: cloning, genetic engineering, prolongation of life, and neurophar-macology. She discusses how texts—young adult literature concerned with bioethics—use the possibility of biotechnology as metaphors for adolescence. Specifically, these new engaging reads for young adults discuss in vivid and clarifying detail the ethics implied in the study and practice of biotechnology—such as the creation of a super class of human beings and the delicate crossing of the boundaries between human and animal, and that age-old fascination, human and machine. Ostry raises a number of startling questions and propositions in regard to the promulgation of young adult literature which examines in full glory the outlines of a new and ever stranger adult world and concludes that most of these contemporary adolescent fictional texts place “nurture above nature” and promote a safe and traditional vision of humanity.
