    Disability, enhancement and the harm -benefit continuum
    In John R. Spencer & Antje Du Bois-Pedain (eds.), Freedom and Responsibility in Reproductive Choice, Hart Publishers. 2006.
    Suppose that you are soon to be a parent and you learn that there are some simple measures that you can take to make sure that your child will be healthy. In particular, suppose that by following the doctor’s advice, you can prevent your child from having a disability, you can make your child immune from a number of dangerous diseases and you can even enhance its future intelligence. All that is required for this to happen is that you (or your partner) comply with lifestyle and dietary requireme…Read more

    Moral enhancement and freedom
    Bioethics 25 (2): 102-111. 2010.
    This paper identifies human enhancement as one of the most significant areas of bioethical interest in the last twenty years. It discusses in more detail one area, namely moral enhancement, which is generating significant contemporary interest. The author argues that so far from being susceptible to new forms of high tech manipulation, either genetic, chemical, surgical or neurological, the only reliable methods of moral enhancement, either now or for the foreseeable future, are either those tha…Read more

    Multiplex parenting: IVG and the generations to come
    with César Palacios-González and Giuseppe Testa
    Journal of Medical Ethics 40 (11): 752-758. 2014.
    Recent breakthroughs in stem cell differentiation and reprogramming suggest that functional human gametes could soon be created in vitro. While the ethical debate on the uses of in vitro generated gametes (IVG) was originally constrained by the fact that they could be derived only from embryonic stem cell lines, the advent of somatic cell reprogramming, with the possibility to easily derive human induced pluripotent stem cells from any individual, affords now a major leap in the feasibility of I…Read more

    The concept of the person and the value of life
    Kennedy Institute of Ethics Journal 9 (4): 293-308. 1999.
    : The concept of the person has come to be intimately connected with questions about the value of life. It is applied to those sorts of beings who have some special value or moral importance and where we need to prioritize the needs or claims of different sorts of individuals. "Person" is a concept designating individuals like us in some important respects, but possibly including individuals who are very unlike us in other respects. What are these respects and why are they important? This paper …Read more

    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…Read more

    Germline Manipulation and Our Future Worlds
    American Journal of Bioethics 15 (12): 30-34. 2015.
    Two genetic technologies capable of making heritable changes to the human genome have revived interest in, and in some quarters a very familiar panic concerning, so-called germline interventions. These technologies are: most recently the use of CRISPR/Cas9 to edit genes in non-viable IVF zygotes and Mitochondrial Replacement Therapy the use of which was approved in principle in a landmark vote earlier this year by the United Kingdom Parliament. The possibility of using either of these techniques…Read more

    Stem cell research, personhood and sentience
    Reproductive Biomedicine Online 10 68-75. 2005.
    In this paper the permissibility of stem cell research on early human embryos is defended. It is argued that, in order to have moral status, an individual must have an interest in its own wellbeing. Sentience is a prerequisite for having an interest in avoiding pain, and personhood is a prerequisite for having an interest in the continuation of one's own existence. Early human embryos are not sentient and therefore they are not recipients of direct moral consideration. Early human embryos do not…Read more

    We argue in this essay that (1) the embryo is an irredeemably ambiguous entity and its ambiguity casts serious doubt on the arguments claiming its full protection or, at least, its protection against its use as a means fo research, (2) those who claim the embryo should be protected as "one of us" are committed to a position even they do not uphold in their practices, (3) views that defend the protection of the embryo in virtue of its potentiality to become a person fail, and (4) the embryo does…Read more

    Ageism and equality
    with Sadie Regmi
    Journal of Medical Ethics 38 (5): 263-266. 2012.
    This paper rebuts suggestions made by Littlejohns et al that NICE is not ageist by analysing the concept of ageism. It recognises the constraints that finite resources impose on decision making bodies such as NICE and then makes a number of positive suggestions as to how NICE might more effectively and more justly intervene in the allocation of scarce resources for health

    Stem Cells, Sex, and Procreation
    Cambridge Quarterly of Healthcare Ethics 12 (4): 353-371. 2003.
    Sex is not the answer to everything, though young men think it is, but it may be the answer to the intractable debate over the ethics of human embryonic stem cell research. In this paper, I advance one ethical principle that, as yet, has not received the attention its platitudinous character would seem to merit. If found acceptable, this principle would permit the beneficial use of any embryonic or fetal tissue that would, by default, be lost or destroyed. More important, I make two appeals to c…Read more

    Opponents of destructive embryo research, such as embryo rightists, as well as proponents accept that natural reproduction is permissible. There is an alternative to natural reproduction—to remain childless. John Harris began this series of articles by asking, what does a commitment to the permissibility of natural reproduction entail? Harris has argued that a commitment to the permissibility of natural reproduction entails a commitment to the permissibility of destructive embryo research. Julia…Read more

    Helping doctors become better doctors: Mary Lobjoit—an unsung heroine of medical ethics in the UK
    with Margaret R. Brazier and Raanan Gillon
    Journal of Medical Ethics 38 (6): 383-385. 2012.
    Medical Ethics has many unsung heros and heroines. Here we celebrate one of these and on telling part of her story hope to place modern medical ethics and bioethics in the UK more centrally within its historical and human contex

    Should we presume moral turpitude in our children? – Small children and consent to medical research
    with Søren Holm
    Theoretical Medicine and Bioethics 24 (2): 121-129. 2003.
    When children are too young to make their ownautonomous decisions, decisions have to be madefor them. In certain contexts we allow parentsand others to make these decisions, and do notinterfere unless the decision clearly violatesthe best interest of the child. In othercontexts we put a priori limits on whatkind of decisions parents can make, and/or whatkinds of considerations they have to take intoaccount. Consent to medical research currentlyfalls into the second group mentioned here. Wewant t…Read more

    Ignorance, information and autonomy
    with Kirsty Keywood
    Theoretical Medicine and Bioethics 22 (5): 415-436. 2001.
    People have a powerful interest in geneticprivacy and its associated claim to ignorance,and some equally powerful desires to beshielded from disturbing information are oftenvoiced. We argue, however, that there is nosuch thing as a right to remain in ignorance,where a right is understood as an entitlementthat trumps competing claims. This doesnot of course mean that information must alwaysbe forced upon unwilling recipients, only thatthere is no prima facie entitlement to beprotected from true o…Read more

    The Immoral Machine
    Cambridge Quarterly of Healthcare Ethics 29 (1): 71-79. 2020.
    :In a recent paper in Nature1 entitled The Moral Machine Experiment, Edmond Awad, et al. make a number of breathtakingly reckless assumptions, both about the decisionmaking capacities of current so-called “autonomous vehicles” and about the nature of morality and the law. Accepting their bizarre premise that the holy grail is to find out how to obtain cognizance of public morality and then program driverless vehicles accordingly, the following are the four steps to the Moral Machinists argument:…Read more

    John Harris has previously proposed that there is a moral duty to participate in scientific research. This concept has recently been challenged by Iain Brassington, who asserts that the principles cited by Harris in support of the duty to research fail to establish its existence. In this paper we address these criticisms and provide new arguments for the existence of a moral obligation to research participation. This obligation, we argue, arises from two separate but related principles. The prin…Read more

    Extending human lifespan and the precautionary paradox
    with Søren Holm
    Journal of Medicine and Philosophy 27 (3). 2002.
    This paper argues that a precautionary approach to scientific progress of the sort advocated by Walter Glannon with respect to life-extending therapies involves both incoherence and irresolvable paradox. This paper demonstrates the incoherence of the precautionary approach in many circumstances and argues that with respect to life-extending therapies we have at present no persuasive reasons for a moratorium on such research.

    Taking the “Human” Out of Human Rights
    Cambridge Quarterly of Healthcare Ethics 20 (1): 9-20. 2011.
    Human rights are universally acknowledged to be important, although they are, of course, by no means universally respected. This universality has helped to combat racism and sexism and other arbitrary and vicious forms of discrimination. Unfortunately, as we shall see, the universality of human rights is both too universal and not universal enough. It is time to take the “human” out of human rights. Indeed, it is very probable that in the future there will be no more humans as we know them now, …Read more

    On Cloning
    Routledge. 2004.
    Cloning - few words have as much potential to grip our imagination or grab the headlines. No longer the stuff of science fiction or Star Wars - it is happening now. Yet human cloning is currently banned throughout the world, and therapeutic cloning banned in many countries. In this highly controversial book, John Harris does a lot more than ask why we are so afraid of cloning. He presents a deft and informed defence of human cloning, carefully exposing the rhetorical and highly dubious arguments…Read more

    Moral enhancement and pro-social behaviour
    with Sarah Chan
    Journal of Medical Ethics 37 (3): 130-131. 2011.
    Moral enhancement is a topic that has sparked much current interest in the world of bioethics. The possibility of making people ‘better,’ not just in the conventional enhancement sense of improving health and other desirable qualities and capacities, but by making them somehow more moral, more decent, altogether better people, has attracted attention from both advocates 1 2 and sceptics 3 alike. The concept of moral enhancement, however, is fraught with difficult questions, theoretical and pract…Read more

    Taking liberties with free fall
    Journal of Medical Ethics 40 (6): 371-374. 2014.
    In his ‘Moral Enhancement, Freedom, and What We Value in Moral Behaviour’,1 David DeGrazia sets out to defend moral bioenhancement from a number of critics, me prominently among them. Here he sets out his stall: "Many scholars doubt what I assert: that there is nothing inherently wrong with MB. Some doubt this on the basis of a conviction that there is something inherently wrong with biomedical enhancement technologies in general. Chief among their objections are the charges that biomedical enha…Read more
