Ideal Observer Theories

In The Sources of Normativity, Korsgaard argues for what can be called “The Universality of Humanity Claim” (UHC), according to which valuing humanity in one’s own person entails valuing it in that of others. However, Korsgaard’s reliance on the claim that reasons are essentially public in her attempt to demonstrate the truth of UHC has been repeatedly criticized. I offer a sentimentalist defense, based on Adam Smith’s moral philosophy, of a qualified, albeit adequate, version of UHC. In particular, valuing my (...) humanity, understood as (my awareness of) my perspective and the reasons determined from within it, entails valuing your humanity, understood as (your awareness of) your perspective and the reasons determined from within it. Given Korsgaard’s emphasis on the publicity of reasons in her argument for UHC, I also discuss the role of reasons in my account. I argue that the relative weights of (at least some of) an agent’s reasons are determined from within a shared evaluative point of view, namely, the standpoint of what Smith calls “the impartial spectator.” These reasons have normative authority over and constrain the agent’s private reasons, that is, those that are determined from within her own particular evaluative point of view.

Some epistemologists think that the Bayesian ideals matter because we can approximate them. That is, our attitudes can be more or less close to the ones of our ideal Bayesian counterpart. In this paper, I raise a worry for this justification of epistemic ideals. The worry is this: In order to correctly compare agents to their ideal counterparts, we need to imagine idealized agents who have the same relevant information, knowledge, or evidence. However, there are cases in which one’s ideal (...) counterpart cannot have one’s information, knowledge, or evidence. In these situations, agents cannot compare themselves to their ideal counterpart. (shrink)

Response-dependence theories have historically been very popular in aesthetics, and aesthetic response-dependence has motivated response-dependence in ethics. This chapter closely examines the prospects for such theories. It breaks this category down into dispositional and fittingness strands of response-dependence, corresponding to descriptive and normative ideal observer theories. It argues that the latter have advantages over the former but are not themselves without issue. Special attention is paid to the relationship between hedonism and response-dependence. The chapter also introduces two aesthetic properties that (...) lead to wrong kinds of reasons problems for aesthetic response-dependence: insightfulness and the capacity to change one’s perspective. These properties do not have obvious parallels in the ethical domain, and so present an obstacle for response-dependence even in aesthetics. The chapter ends by examining replies on behalf of the response-dependence theorist, ultimately suggesting that a restricted form of response-dependence is the most promising way forward for fans of such theories.

Sentimentalism comes in many varieties: explanatory sentimentalism, judgment sentimentalism, metaphysical sentimentalism, and epistemic sentimentalism. This encyclopedia entry gives an overview of the positions and main arguments pro and con.

I build on Adam Smith’s account of the impartial spectator in The Theory of Moral Sentiments in order to offer a modest ideal observer theory of moral judgment that is adequate in the following sense: the account specifies the hypothetical conditions that guarantee the authoritativeness of an agent’s (or agents’) responses in constituting the standard in question, and, if an actual agent or an actual community of agents are not under those conditions, their responses are not authoritative in setting this (...) standard. However, in the account that I provide, the hypothetical conditions can themselves be constructed from the psychology and interactions of actual human beings. In other words, facts about the morally appropriate and inappropriate are determined from hypothetical conditions that––while agents in a given society might have yet to attain them––can be constructed from those agents’ shared experiences. Thus, the account offers both an attainable standard of moral judgment and a standard that can transcend the biases of the society which gave rise to it. I also defend the account against three challenges: (a) ideal observer theories do not offer the right kind of motivation to act on the verdicts of the ideal observer; (b) ideal observer theories cannot explain why the idealization in question is well-motivated and not objectionably ad hoc; (c) the standard used in ideal observer theories cannot be defended upon further reflection, because we would need a non-arbitrary, second-order standard to govern our reflection on the first-order standard of moral judgment.

What is the relevance of ideals for determining virtuous argumentative practices? According to Bailin and Battersby (2016), the telos of argumentation is to improve our cognitive systems, and adversariality plays no role in ideally virtuous argumentation. Stevens and Cohen (2019) grant that ideal argumentation is collaborative, but stress that imperfect agents like us should not aim at approximating the ideal of argumentation. Accordingly, it can be virtuous, for imperfect arguers like us, to act as adversaries. Many questions are left unanswered (...) by both camps. First, how do we conceptualize an ideal and its approximation? Second, how can we determine what is the ideal of argumentation? Third, can we extend Stevens and Cohen’s anti-approximation argument beyond virtue theory? In order to respond to these questions, this paper develops a second-best perspective on ideal argumentation. The Theory of the Second Best is a formal contribution to the field of utility (or welfare) optimization. Its main conclusion is that, in non-ideal circumstances, approximating ideals might be suboptimal. (shrink)

This essay shows that a moral sense or moral sentiments alone cannot identify appropriate morals. To this end, the essay analyzes three defenses of Francis Hutcheson's, David Hume's, and Adam Smith's moral sense theories against the relativism charge that a moral sense or moral sentiments vary across people, societies, cultures, or times. The first defense is the claim that there is a universal moral sense or universal moral sentiments. However, even if they exist, a moral sense or moral sentiments alone (...) cannot identify appropriate morals. The second defense is to adopt a general viewpoint theory, which identifies moral principles by taking a general viewpoint. But it needs to employ reason, and even if not, it does not guarantee that we identify appropriate morals. The third defense is to adopt an ideal observer theory, which draws moral principles from sentimental reactions of an ideal observer. Yet it still does not show that a moral sense or moral sentiments alone can identify appropriate morals. (shrink)

In recent discussions of whether our lives are or can be meaningful, appeals are often made to such things as “a view from nowhere,” or “the viewpoint of the universe.” In this paper I attempt to make sense of what it might mean for a being to possess such a perspective, and argue that common appeals to such perspectives are inadequately developed; crucially, they do not adequately account for the character of the beings taken to possess these viewpoints. In the (...) second half of the paper I turn to an alternative proposal, one that focuses on the attitudes of virtuous ideal observers in determining the normative statuses of our lives and activities, and argue that it provides a plausible account of meaningfulness.

To lead an environmentally virtuous life requires information—about morality, environmental issues, the impacts of our actions and commitments, our options for alternatives, and so on. On the other hand, we are finite beings with limited time and resources. We cannot feasibly investigate all of our options, and all environmental issues (let alone moral issues, more broadly). In this paper I attempt to provide initial steps towards addressing the epistemic demands of environmental virtue. In the first half of the paper I (...) provide rules of thumb with respect to (1) how to prioritize our investigations into various issues, and (2) what kinds of information we should seek with respect to these issues, and the levels of epistemic justification we ought to attain. In the second half of the paper, I turn to a modified virtue ethics, appealing to the attitudes of virtuous ideal observers to provide characterizations of morally justified and morally non-culpable actions. I then apply these latter concepts in assessing agents, their actions and projects (with respect to environmental virtue), in light of their investigative efforts, and given their particular circumstances.

I argue that recent virtue theories (including those of Hursthouse, Slote, and Swanton) face important initial difficulties in accommodating the supererogatory. In particular, I consider several potential characterizations of the supererogatory modeled upon these familiar virtue theories (and their accounts of rightness) and argue that they fail to provide an adequate account of supererogation. In the second half of the paper I sketch an alternative virtue-based characterization of supererogation, one that is grounded in the attitudes of virtuous ideal observers, and (...) that avoids the concerns raised in the first part of the paper.

: In this paper I attempt to defuse a set of epistemic worries commonly raised against ideal observer theories. The worries arise because of the omniscience often attributed to ideal observers – how can we, as finite humans, ever have access to the moral judgements or reactions of omniscient beings? I argue that many of the same concerns arise with respect to other moral theories (and that these concerns do not in fact reveal genuine flaws in any of these theories), (...) and further, that we can and often do have knowledge of the reactions of ideal observers (according to standard, prominent theories in the domain of epistemology).

Moral response-dependent metaethical theories characterize moral properties in terms of the reactions of certain classes of individuals. Nick Zangwill has argued that such theories are flawed: they are unable to accommodate the motive of duty. That is, they are unable to provide a suitable reason for anyone to perform morally right actions simply because they are morally right. I argue that Zangwill ignores significant differences between various approvals, and various individuals, and that moral response-dependent theories can accommodate the motive of (...) duty.

Virtue theorists in ethics often embrace the following characterizationof right action: An action is right iff a virtuous agent would performthat action in like circumstances. Zagzebski offers a parallel virtue-basedaccount of epistemically justified belief. Such proposals are severely flawedbecause virtuous agents in adverse circumstances, or through lack ofknowledge can perform poorly. I propose an alternative virtue-based accountaccording to which an action is right (a belief is justified) for an agentin a given situation iff an unimpaired, fully-informed virtuous observerwould deem the (...) action to be right (the belief to be justified).
