Many philosophers believe that there exist distinctive obstacles to relying on moral testimony. In this paper, I criticize previous attempts to identify these obstacles and offer a new theory. I argue that the problems associated with moral deference can't be explained in terms of the value of moral understanding, nor in terms of aretaic considerations related to subjective integration. Instead, our uneasiness with moral testimony is best explained by our attachment to an ideal of authenticity that places special demands on (...) our moral beliefs. (shrink)

Many moral philosophers accept the Debunking Thesis, according to which facts about natural selection provide debunking explanations for certain of our moral beliefs. I argue that philosophers who accept the Debunking Thesis beg important questions in the philosophy of biology. They assume that past selection can explain why you or I hold certain of the moral beliefs we do. A position advanced by many prominent philosophers of biology implies that this assumption is false. According to the Negative View, natural selection (...) cannot explain the traits of individuals. Hence, facts about past selection cannot provide debunking explanations for any of our moral beliefs. The aim of this paper is to explore the conflict between the Debunking Thesis and the Negative View. (shrink)

Upon discovering that certain beliefs we hold are contingent on arbitrary features of our background, we often feel uneasy. I defend the proposal that if such cases of contingency anxiety involve defeaters, this is because of the epistemic significance of disagreement. I note two hurdles to our accepting this Disagreement Hypothesis. Firstly, some cases of contingency anxiety apparently involve no disagreement. Secondly, the proposal may seem to make our awareness of the influence of arbitrary background factors irrelevant in determining whether (...) to revise our beliefs. I show that each of these problems can be successfully accommodated by the Disagreement Hypothesis. (shrink)

Many philosophers believe that natural selection explanations debunk our moral beliefs or would do so if moral realism were true, relying on the assumption that explanations of this kind show that moral facts play no role in explaining human moral beliefs. Here I argue that this assumption rests on a confusion of proximate and ultimate explanatory factors. Insofar as evolutionary debunking arguments hinge on the assumption that moral facts play no role in explaining human moral beliefs, these arguments fall short.

People may disagree about moral issues because they have fundamentally different intuitions. I argue that we ought to suspend judgement in such cases. Since we trust our own moral intuitions without positive evidence of their reliability, we must necessarily extend this trust to the moral intuitions of others: a fundamental self-other asymmetry in moral epistemology is untenable. This ensures that disagreements in moral intuition are defeating. In addition, I argue that brute conflicts in moral intuition require suspension of judgement only (...) if we are required to exhibit this kind of default trust with respect to the moral intuitions of others.

Given the inevitability of scarcity, should public institutions ration healthcare resources so as to prioritize those who contribute more to society? Intuitively, we may feel that this would be somehow inegalitarian. I argue that the egalitarian objection to prioritizing treatment on the basis of patients’ usefulness to others is best thought of as semiotic: i.e. as having to do with what this practice would mean, convey, or express about a person's standing. I explore the implications of this conclusion when taken (...) in conjunction with the observation that semiotic objections are generally flimsy, failing to identify anything wrong with a practice as such and having limited capacity to generalize beyond particular contexts.

When our choice affects some other person and the outcome is unknown, it has been argued that we should defer to their risk attitude, if known, or else default to use of a risk‐avoidant risk function. This, in turn, has been claimed to require the use of a risk‐avoidant risk function when making decisions that primarily affect future people, and to decrease the desirability of efforts to prevent human extinction, owing to the significant risks associated with continued human survival. I (...) raise objections to the claim that respect for others' risk attitudes requires risk‐avoidance when choosing for future generations. In particular, I argue that there is no known principle of interpersonal aggregation that yields acceptable results in variable population contexts and is consistent with a plausible ideal of respect for others' risk attitudes in fixed population cases.

Certain of our traits are thought more central to who we are: they comprise our individual identity. What makes these traits privileged in this way? What accounts for their identity centrality? Although considerations of identity play a key role in many different areas of moral philosophy, I argue that we currently have no satisfactory account of the basis of identity centrality. Nor should we expect one. Rather, we should adopt an error theory: we should concede that there is nothing in (...) reality corresponding to the perceived distinction between the central and peripheral traits of a person.

Some believe that the current era is uniquely important with respect to how well the rest of human history goes. Following Parfit, call this the Hinge of History Hypothesis. Recently, MacAskill has argued that our era is actually very unlikely to be especially influential in the way asserted by the Hinge of History Hypothesis. I respond to MacAskill, pointing to important unresolved ambiguities in his proposed definition of what it means for a time to be influential and criticizing the two (...) arguments used to cast doubt on the claim that the current era is a uniquely important moment in human history.

According to the Psychological Account of personal identity, personal identity across time is maintained by some form of psychological overlap or continuance. I show that the Psychological Account has trouble accommodating cases of transient retrograde amnesia. In such cases, the transitivity of psychological continuity may break down. I consider various means of responding to this problem, arguing that the best available response will undercut our ability to rely on intuitions about brain transplantation to support the Psychological Account. When the Psychological (...) Account is re-interpreted in such a way as to overcome the problems posed by cases of transient retrograde amnesia, it turns out that standard brain transplantation cases involve details which are strictly irrelevant according to the theory. On the other hand, these features seem to drive our intuitions about survival in these cases. In this way, my argument undermines one of the key motivations for adopting the Psychological Account.

This paper aims to open a dialogue between philosophers working in decision theory and operations researchers and engineers working on decision-making under deep uncertainty. Specifically, we assess the recommendation to follow a norm of robust satisficing when making decisions under deep uncertainty in the context of decision analyses that rely on the tools of Robust Decision-Making developed by Robert Lempert and colleagues at RAND. We discuss two challenges for robust satisficing: whether the norm might derive its plausibility from an implicit (...) appeal to probabilistic representations of uncertainty of the kind that deep uncertainty is supposed to preclude; and whether there is adequate justification for adopting a satisficing norm, as opposed to an optimizing norm that is sensitive to considerations of robustness. We discuss decision-theoretic and voting-theoretic motivations for robust satisficing, and use these motivations to select among candidate formulations of the robust satisficing norm. (shrink)

I argue that there are cases in which ecumenical expressivism cannot distinguish between endorsement of certain trivial and substantive normative judgments. I consider the extent to which this problem generalizes across different formulations of the ecumenical view. I suggest that we may not be able to escape the problem if we hope to retain the ability to solve the Frege-Geach problem in the way promised by ecumenical expressivism.
