As the news constantly reminds us, recent advances in the biomedical sciences have brought within reach things that were unthinkable only a few years ago: designer babies, genetically enhanced athletes, human clones, stem cell treatment, medical technology, transhumanism. All these issues raise huge questions. Our power to intervene in the natural course of human life is immense: but what should we be doing and what should we avoid? And what about the inequalities of technological power across the globe? Biologist and ethics expert Dr John Bryant begins by placing modern biomedical science in its recent social history context, before moving on to discuss ethics and whether our normal ethical frameworks can cope with the questions thrown up by these huge issues. Throughout the book, Bryant encourages the reader to engage with the questions he addresses.
