    Artefacts are often regarded as being mere things that possess only instrumental value. In contrast, living entities (or some subset of them) are often regarded as possessing some form of intrinsic (or non-instrumental) value. Moreover, in some cases they are thought to possess such value precisely because they are natural (i.e., non-artefactual). However, living artefacts are certainly possible, and they may soon be actual. It is therefore necessary to consider whether such entities should be r…Read more

    Enhancing justice?
    with Tamara Garcia
    NanoEthics 2 (3): 277-287. 2008.
    This article focuses on the follow question: Are human enhancement technologies likely to be justice impairing or justice promoting? We argue that human enhancement technologies may not be inherently just or unjust, but when situated within obtaining social contexts they are likely to exacerbate rather than alleviate social injustices.

    The external goods approach to environmental virtue ethics
    Environmental Ethics 25 (3): 279-293. 2003.
    If virtue ethics are to provide a legitimate alternative for reasoning about environmental issues, they must meet the same conditions of adequacy as any other environmental ethic. One such condition that most environmental ethicists insist upon is that an adequate environmental ethic provides a theoretical platform for consistent and justified critique of environmentally unsustainable practices and policies. The external goods approach seeks to establish that any genuinely virtuous agent will be…Read more

    Ethical Theory and the Problem of Inconsequentialism: Why Environmental Ethicists Should be Virtue-Oriented Ethicists (review)
    Journal of Agricultural and Environmental Ethics 23 (1-2): 167-183. 2009.
    Many environmental problems are longitudinal collective action problems. They arise from the cumulative unintended effects of a vast amount of seemingly insignificant decisions and actions by individuals who are unknown to each other and distant from each other. Such problems are likely to be effectively addressed only by an enormous number of individuals each making a nearly insignificant contribution to resolving them. However, when a person’s making such a contribution appears to require sacr…Read more

    Martin Calkins proposes the “combined use of casuistry and virtue ethics as a way for both sides to move ahead on [the] pressing issue [of agricultural biotechnology].” However, his defense of this methodology relies on a set of mistaken, albeit familiar, claims regarding the normative resources of virtue ethics: (1) virtue ethics is egoistic; (2) virtue ethics cannot defend any particular account of the virtues as the objectively correct ones and is therefore inextricably relativistic; (3) virt…Read more

    The Value of Artefactual Organisms
    Environmental Values 21 (1). 2012.
    Synthetic biology makes use of genetic and other materials derived from modern biological life forms to design and construct novel synthetic organisms. Artificial organisms are not constructed from parts of existing biological organisms, but from non-biological materials. Artificial and synthetic organisms are artefactual organisms. Here we are concerned with the non-instrumental value of such organisms. More specifically, we are concerned with the extent to which artefactual organisms have natu…Read more
