Virtue ethics has been challenged on empirical grounds by philosophical interpreters of situationist social psychology. Challenges are necessarily challenges to something or other, so it’s only possible to understand the situationist challenge to virtue ethics if we have an antecedent grasp on virtue ethics itself. To this end, I first identify the non-negotiable “hard core” of virtue ethics with the conjunction of nine claims, arguing that virtue ethics does make substantive empirical assumptions about human conduct. Next, I rearticulate the situationist (...) challenge in light of these nine claims. I then turn to a discussion of specifications of several responses typically made by defenders of virtue ethics against the situationist challenge, arguing that most of them either are unsound or give up one of the elements in the hard core. A few, however, survive this criticism, and so I conclude by suggesting ways in which the situationist challenge might be not so much resisted as co-opted. Situational influences can be used to help people simulate virtue, a phenomenon I call factitious virtue. (shrink)

Philosophical investigation in synthetic biology has focused on the knowledge-seeking questions pursued, the kind of engineering techniques used, and on the ethical impact of the products produced. However, little work has been done to investigate the processes by which these epistemological, metaphysical, and ethical forms of inquiry arise in the course of synthetic biology research. An attempt at this work relying on a particular area of synthetic biology will be the aim of this chapter. I focus on the reengineering of (...) metabolic pathways through the manipulation and construction of small DNA-based devices and systems synthetic biology. Rather than focusing on the engineered products or ethical principles that result, I will investigate the processes by which these arise. As such, the attention will be directed to the activities of practitioners, their manipulation of tools, and the use they make of techniques to construct new metabolic devices. Using a science-in-practice approach, I investigate problems at the intersection of science, philosophy of science, and sociology of science. I consider how practitioners within this area of synthetic biology reconfigure biological understanding and ethical categories through active modelling and manipulation of known functional parts, biological pathways for use in the design of microbial machines to solve problems in medicine, technology, and the environment. We might describe this kind of problem-solving as relying on what Helen Longino referred to as “social cognition” or the type of scientific work done within what Hasok Chang calls “systems of practice”. My aim in this chapter will be to investigate the relationship that holds between systems of practice within metabolic engineering research and social cognition. I will attempt to show how knowledge and normative valuation are generated from this particular network of practitioners. In doing so, I suggest that the social nature of scientific inquiry is ineliminable to both knowledge acquisition and ethical evaluations. (shrink)

A virtue-based theory of right action aims to explain deontic moral principles in terms of virtue and vice. For example, it may maintain the following account of moral obligation: It is morally obligatory for an agent A to ϕ in circumstances C if and only if a fully virtuous and relevantly informed person V would characteristically ϕ in C. However, this account faces the so-called supererogation problem. A supererogatory action is an action that is morally praiseworthy but not morally obligatory. (...) Suppose John risks his own life to save a stranger, which is supererogatory rather than obligatory. However, a fully virtuous... (shrink)

In this essay several challenges are raised to the project of classifying Śāntideva’s ethical reasoning given in his Bodhicaryāvatāra, or Guide to the Way of the Bodhisattva, as a species of ethical theory such as consequentialism or virtue ethics. One set of difficulties highlighted here arises because Śāntideva wrote this text to act as a manual of psychological transformation, and it is therefore often difficult to determine when his statements indicate his own ethical views. Further, even assuming we can identify (...) a set of statements that accurately portray the moral position of Śāntideva, it is argued that these statements underdetermine which foundational normative theory should be ascribed to him.
