Should we make people healthier, smarter, and longer-lived if genetic and medical advances enable us to do so? Matti Häyry asks this question in the context of genetic testing and selection, cloning and stem cell research, gene therapies and enhancements. The ethical questions explored include parental responsibility, the use of people as means, the role of hope and fear in risk assessment, and the dignity and meaning of life. Taking as a starting point the arguments presented by Jonathan Glover, John (...) Harris, Ronald M. Green, Jürgen Habermas, Michael J. Sandel, and Leon R. Kass, who defend a particular normative view as the only rational or moral answer, Matti Häyry argues that many coherent rationalities and moralities exist in the field, and that to claim otherwise is mistaken"--Provided by publisher.

Discusses the ethical implications of modern technology and examines the responsibility of humanity for the fate of the world.

Challenging, with several powerful arguments, some of our deepest beliefs about rationality, morality, and personal identity, Parfit claims that we have a false view about our own nature. It is often rational to act against our own best interersts, he argues, and most of us have moral views that are self-defeating. We often act wrongly, although we know there will be no one with serious grounds for complaint, and when we consider future generations it is very hard to avoid conclusions (...) that most of us will find very disturbing.

In Enhancing Evolution, leading bioethicist John Harris dismantles objections to genetic engineering, stem-cell research, designer babies, and cloning and makes an ethical case for biotechnology that is both forthright and rigorous. Human enhancement, Harris argues, is a good thing--good morally, good for individuals, good as social policy, and good for a genetic heritage that needs serious improvement. Enhancing Evolution defends biotechnological interventions that could allow us to live longer, healthier, and even happier lives by, for example, providing us with immunity (...) from cancer and HIV/AIDS. Further, Harris champions the possibility of influencing the very course of evolution to give us increased mental and physical powers--from reasoning, concentration, and memory to strength, stamina, and reaction speed. Indeed, he says, it's not only morally defensible to enhance ourselves; in some cases, it's morally obligatory. In a new preface, Harris offers a glimpse at the new science and technology to come, equipping readers with the knowledge to assess the ethics and policy dimensions of future forms of human enhancement.

Since human reproduction is arguably both irrational and immoral, those who seek help before conceiving could be advised it is all right not to have children.

Progress in genetic and reproductive technology now offers us the possibility of choosing what kinds of children we do and don't have. Should we welcome this power, or should we fear its implications? There is no ethical question more urgent than this: we may be at a turning-point in the history of humanity. The renowned moral philosopher and best-selling author Jonathan Glover shows us how we might try to answer this question, and other provoking and disturbing questions to which it (...) leads. Surely parents owe it to their children to give them the best life they can? Increasingly we are able to reduce the number of babies born with disabilities and disorders. But there is a powerful new challenge to conventional thinking about the desirability of doing so: this comes from the voices of those who have these conditions. They call into question the very definition of disability. How do we justify trying to avoid bringing people like them into being? In 2002 a deaf couple used sperm donated by a friend with hereditary deafness to have a deaf baby: they took the view that deafness is not a disability, but a difference. Starting with the issues raised by this case, Jonathan Glover examines the emotive idea of 'eugenics', and the ethics of attempting to enhance people, for non-medical reasons, by means of genetic choices. Should parents be free, not only to have children free from disabilities, but to choose, for instance, the colour of their eyes or hair? This is no longer a distant prospect, but an existing power which we cannot wish away. What impact will such interventions have, both on the individuals concerned and on society as a whole? Should we try to make general improvements to the genetic make-up of human beings? Is there a central core of human nature with which we must not interfere? This beautifully clear book is written for anyone who cares about the rights and wrongs of parents' choices for their children, anyone who is concerned about our human future. Glover handles these uncomfortable questions in a controversial but always humane and sympathetic manner. (shrink)

From the first initiatives in preimplantation genetic diagnosis and gene therapy through the advent of stem cell research to the development of mammalian cloning, the past two decades have witnessed remarkable advances in “reprogenetic” medicine: the union of assisted reproductive technologies with genetic control. This period has also been marked by intense debates within the bioethical literature and in national policy forums about the appropriate uses of these emerging human capabilities. We can now, in a limited way, select for genetic (...) traits, and the power to modify the genome or introduce new gene sequences is not far off. How should these new powers be used? (shrink)

Recent developments in genomic science hold out the tantalizing prospect of soon being able to treat and prevent a wide variety of medical conditions through gene therapy. In time, it may be possible to use similar techniques not simply to combat disease but also to enhance, or improve on, normal human functioning.

There must be few philosophical projects more serious than Jürgen Habermas’s lifelong effort to realize the lofty universalist ambitions of the Enlightenment in his communicative theory of rational discourse and deliberative democracy.

Matti Häyry’s new book Rationality and the Genetic Challenge discusses the ethics of human genetic modification and the bioethical rationalities that inform the different ethical conclusions authors have advanced. It is aimed at correcting the belief that “only one rationality exists or one morality exists; that those that disagree [with them] are unreasonable or evil.” Häyry argues that there are multiple rationalities, and that even though ethical issues may have solutions within individual rationalities, disagreements that have their root in separate (...) rational approaches cannot be universally solved by intellectual arguments. In debates about the ethics of using new biotechnologies to genetically modify human beings, the normal state is one of fundamental disagreement over almost all of the anticipated uses to which the technology could be put. Häyry’s point is that such a state of affairs is not necessarily due to a lack of reason because there are many, equally valid, ways of being reasonable. (shrink)

Rationality and the Genetic Challenge by Matti Häyry is a well-written and thoughtful book about important issues in the contemporary ethical discussion of genetics. The book is well structured around seven practical themes that the author takes to exemplify “the genetic challenge.” He also refers to them as “seven ways of making people better,” which the subtitle of the book already puts into question form: Making People Better? In the first chapter of the book, Häyry introduces these seven themes and (...) he discusses each of them in Chapters 3–9. In the remaining two chapters, 2 and 10, he describes the main normative positions analyzed in the book and clarifies his own methodology and position. He chooses six authors, or three pairs of authors, whom he takes to “represent the three normative doctrines of Western Moral philosophy” in order to demonstrate six “divergent rationalities” or “methods of genethics.” In this way, Häyry both summarizes the main prescriptive positions in contemporary bioethical debate and contrasts them with his own “nonconfrontational notion of rationality,” which aims to show that there is a variety of divergent, not mutually exclusive normative views, the justification of which “depends ultimately on the choice of worldviews, attitudes, and ideas about the foundation of moral worth”.

The overarching question addressed in this article is whether there is something that might reasonably be called a Habermasian approach or perspective that bioethical enquiry might utilize.
