Abstract

Experimental ethicists investigate traditional ethical questions with nontraditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought
experiments such as the well-known trolley cases. Yet, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempt to fill this gap. We begin by describing the function of ethical thought experiments, and show that these thought experiments should not only be classified according to their function but also according to their scope. On this basis we highlight several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. We conclude by arguing that experimental philosophy currently only focuses on a small subcategory of ethical thought experiments and suggest a broadening of its research agenda.

Conclusion

Experimental ethicists investigate traditional ethical questions with nontraditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought experiments such as the well-known trolley cases. Yet, for some reason, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempted to fill this gap. First, we described the function of ethical thought experiments, distinguishing between an epistemic, an illustrative and a heuristic function. We also showed that ethical thought experiments should not only be classified according to their function but also according to their scope. Some ethical thought experiments (such as the veil) can be applied to a variety of moral issues. On the basis of this understanding of thought experiments we highlighted several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. Such studies can in particular inform us about the content of the intuitions that people have about ethical thought experiments, these intuitions’ sensitivity to irrelevant factors, and their diversity. Finally, we suggested that experimental ethics broadens its research agenda to include investigations into illustrative and heuristic thought experiments, wide-scope thought experiments, de-biasing strategies, atypical thought experiments, and philosophers’ intuitions about thought experiments. In any case, since experimental ethics heavily relies on thought experiments, an increased theoretical engagement with their function and implications is likely to benefit the field. It is our hope that this paper contributes to promoting such an engagement.
