Three ways of approaching controversial issues are: (i) To accept the conclusions of experts on their authority; (ii) to evaluate the relevant evidence/arguments for ourselves; and (iii) to simply withhold judgement. The received view recommends strategy (ii). But (ii) is normally epistemically inferior to (i) and (iii), since we are justified in believing that it is less reliable at producing true beliefs and avoiding false ones.

Using the bench trial of Colorado’s Amendment 2 as an example, this article focuses on the more general question of expert testimony in moral philosophy. It argues that there is indeed expertise in moral philosophy but argues against admitting such expert testimony in cases dealing with what John Rawls terms “constitutional essentials” and ‘matters of basic justice.” Developing the idea of public reason inherent in the Rawlsian concept of political liberalism, the article argues that philosophers can and should speak out (...) on public issues, if they do so with due respect for certain restrictions, but that they should not serve as expert witnesses on core constitutional questions, since doing so suggests that they claim a type of authority that would require fellow citizens to defer to their views. Such claims to authority in basic ethical matters threaten the mutual respect for divergent comprehensive doctrines that lies at the core of political liberalism. Philosophers have a duty to serve the public good, and they perform this service in fruitful ways. But they should refuse a public role that appears incompatible with equal respect for the committed ethical searching of their fellow citizens. (shrink)

We examined the effects of order of presentation on the moral judgments of professional philosophers and two comparison groups. All groups showed similar-sized order effects on their judgments about hypothetical moral scenarios targeting the doctrine of the double effect, the action-omission distinction, and the principle of moral luck. Philosophers' endorsements of related general moral principles were also substantially influenced by the order in which the hypothetical scenarios had previously been presented. Thus, philosophical expertise does not appear to enhance the stability (...) of moral judgments against this presumably unwanted source of bias, even given familiar types of cases and principles.

Philosophers have harbored doubts about the possibility of moral expertise since Plato. I argue that irrespective of whether moral experts exist, identifying who those experts are is insurmountable because of the credentials problem: Moral experts have no need to seek out others’ moral expertise, but moral non-experts lack sufficient knowledge to determine whether the advice provided by a putative moral expert in response to complex moral situations is correct and hence whether an individual is a bone fide expert. Traditional accounts (...) of moral expertise require that moral experts give reliably correct moral advice supported by adequate justification, an account which, I argue, is too lean in allowing for the possibility of a moral expert who is motivationally indifferent to her own moral judgments and advice. Yet even if the proposition that a moral expert is an individual who provides reliably correct moral advice supported by adequate justification and is necessarily motivated by that advice exhausts the necessary and sufficient conditions for moral expertise, this proposition cannot function as an applicable criterion for non-experts to use in appraising would-be experts’ claims to expertise. The credentials problem thus remains unanswered. (shrink)

This book is the first systematic treatment of 'responsibilist' or character-based virtue epistemology, an approach to epistemology that focuses on intellectual ...

Disagreement is common: even informed, intelligent, and generally reasonable people often come to different conclusions when confronted with what seems to be the same evidence. Can the competing conclusions be reasonable? If not, what can we reasonably think about the situation? This volume examines the epistemology of disagreement. Philosophical questions about disagreement arise in various areas, notably politics, ethics, aesthetics, and the philosophy of religion: but this will be the first book focusing on the general epistemic issues arising from informed (...) disagreement. Ten leading philosophers offer specially written essays which together will offer a starting-point for future work on this topic. (shrink)
