Peer Disagreement

It is often irrational to believe philosophical claims because they are subject to systematic disagreement, under-determination, and pessimistic induction. Along with some other authors in this volume, I argue that many philosophers should (and do) have a different attitude to their own philosophical commitments. On my account, this attitude is a form of epistemic acceptance called endorsement. However, several objections have been raised to this view and others like it. One worry is that endorsement is spineless: that people who merely (...) endorse their theories fail to have a stable, global commitment to their views. A second worry is that endorsement, and the assertions it licenses, are objectionably insincere. Here, I defend the theory of endorsement from these objections. I suggest that endorsement can be more resilient than belief, while better supporting both intellectual courage and humility. Then, I argue that endorsement can be perfectly sincere, since it is not deceptive. (shrink)

The problem of religious disagreement between epistemic peers is a potential threat to the epistemic justification of one’s theistic belief. In this paper, I develop a response to this problem which draws on the central epistemological thesis of skeptical theism concerning our inability to make proper judgements about God’s reasons for permitting evil. I suggest that this thesis may extend over to our judgements about God’s reasons for self-revealing, and that when it does so, it can enable theists to remain (...) steadfast amid disagreement with epistemic peers who hold a contrary theistic belief (i.e., atheistic belief). For if we’re unable to make proper judgements about God’s reasons for self-revealing, then for all we know, God has some reason for not revealing Himself to our apparent epistemic peer. Thus, their epistemic credentials needn’t provide reason to reduce one’s confidence to such a degree as to no longer uphold one’s theistic belief. (shrink)

I present a counterexample to Kirk-Giannini’s Dilemmatic Theory of gaslighting.

In his book Meinungsverschiedenheiten (engl.: Disagreement) Marc Andree Weber defends a probability based conception of epistemic peerhood. Starting from this conception he proves the equal weight thesis, which prescribes that one should allocate the same weight to the beliefs of epistemic peers as to one's own beliefs. – In the present article I provide a much shorter proof. For that purpose I first formalize Weber's definition and thesis and I close the argumentative gap between the two of them by making (...) relatively few additions. Toward the end, I will document the differences between Weber's proof and my proof and indicate the relevance of a second proof. No judgmental assessment will be sought. (shrink)

(OPEN ACCESS) This paper establishes moral duties for intermediaries of political advertising in election campaigns. First, I argue for a collective duty to maintain the democratic quality of elections which entails a duty to contain some forms of political polarization. Second, I show that the focus of campaign ethics on candidates, parties and voters—ignoring the mediators of campaigns—yields mistaken conclusions about how the burdens of the latter collective duty should be distributed. Third, I show why it is fair to require (...) intermediaries to contribute to fulfilling this duty: they have an ultimate filtering position in the campaign communication process and typically benefit from political advertising and polarization. Finally, I argue that a transparency-based ethics of campaign advertising cannot properly accommodate a concern with objectionable polarization. By contrast, I outline the polarization-containing implications of my account, including a prohibition on online targeted advertising, and intermediaries’ duties to block hateful political advertising.

Unknown peers create a problem for those epistemologists who argue that we should be conciliatory in cases of peer disagreement. The standard interpretation of ‘being conciliatory’ has it that we should revise our opinions concerning a specific subject matter whenever we encounter someone who is as competent and well informed as we are concerning this subject matter (and thus is our peer) and holds a different opinion. As a consequence, peers whom we have never encountered and who are hence unknown (...) to us are not taken into account. This, however, appears odd; not only because it is an accidental matter which peers we happen to encounter and which not, but also because it would allow people to deliberately isolate themselves from any kind of intellectual exchange on the topic under consideration. The paper argues that we should take the problem of unknown peers seriously, and that disregarding the problem is an instance of the more general mistake of assuming that evidential quality and justified believability can be dealt with separately. Moreover, a solution to the problem of unknown peers is suggested. (shrink)

The evidence that we get from peer disagreement is especially problematic from a Bayesian point of view since the belief revision caused by a piece of such evidence cannot be modelled along the lines of Bayesian conditionalisation. This paper explains how exactly this problem arises, what features of peer disagreements are responsible for it, and what lessons should be drawn for both the analysis of peer disagreements and Bayesian conditionalisation as a model of evidence acquisition. In particular, it is pointed (...) out that the same characteristic of evidence from disagreement that explains the problems with Bayesian conditionalisation also suggests an interpretation of suspension of belief in terms of imprecise probabilities.

Many of our ideological, political, moral, religious, aesthetic, scientific beliefs, as well as those concerning everyday life, are controversial; other people do not share them. As a rule, that does not bother us much: we tend to retain our contestable beliefs even if we ascribe no less skill and well-informedness to those who represent other points of view than to ourselves. But is that really reasonable? Shouldn't we often admit that we might be as wrong as others? And if we (...) do, shouldn't this consequently lead us to give up many of our beliefs in favor of agnostic attitudes? Marc Andree Weber argues that in the face of disagreement with equally competent and well-informed interlocutors we should almost always refrain from insisting on our controversial beliefs – with the few exceptions being all the more remarkable.

A commonly neglected feature of the so-called Equal Weight View, according to which we should give our peers’ opinions the same weight we give our own, is its prima facie incompatibility with the common picture of philosophy as an armchair activity: an intellectual effort to seek a priori knowledge. This view seems to imply that our beliefs are more likely to be true if we leave our armchair in order to find out whether there actually are peers who, by disagreeing (...) with us, force us to revise our beliefs. This article argues that the Equal Weight View should be spelled out in such a way that not only actual peer disagreement requires us to revise our beliefs, but also merely possible peer disagreement. This result is not a reductio ad absurdum of the view. Quite the opposite: it shows that the view is, contrary to appearance, compatible with our common way of doing philosophy. (shrink)

Standardly, epistemic peers regarding a given matter are said to be people of equal competence who share all relevant evidence. Alternatively, one can define epistemic peers regarding a given matter as people who are equally likely to be right about that matter. I argue that a definition in terms of likelihood captures the essence of epistemic peerhood better than the standard definition or any variant of it. What is more, a likelihood definition implies the truth of the central thesis in (...) the debate on peer disagreement, the so-called Equal Weight View, according to which we should give the opinions of our peers the same weight we give our own. Adopting a likelihood definition, however, does not end the debate on peer disagreement, because the alleged theoretical alternatives to the Equal Weight View, reinterpreted in the light of a likelihood definition, can in fact be shown to be compatible with this view—though the reinterpreted versions may appear less plausible than the original ones.

In this paper I present a criticism of Sarah Moss‘ recent proposal to use scoring rules as a means of reaching epistemic compromise in disagreements between epistemic peers that have encountered conflict. The problem I have with Moss‘ proposal is twofold. Firstly, it appears to involve a double counting of epistemic value. Secondly, it isn‘t clear whether the notion of epistemic value that Moss appeals to actually involves the type of value that would be acceptable and unproblematic to regard as (...) epistemic.

The paper is a defense of the thesis that there are situations in which morally virtuous persons who are epistemic peers may disagree about what to do without either person being rationally required to change his or her judgment (a version of the Steadfast position in the epistemology of disagreement debate). The argument is based in part on similarities between decisions of virtuous agents and other practical decisions such as a baseball manager’s decision to change pitchers during a game. In (...) both cases, the role and responsibilities of the person making the decision and the complexities of the decision favor the Steadfast position. At the end of the paper, the argument for this position is compared with discussions of traditional arguments against moral objectivity that are based onmoral disagreements, and it is suggested that they involve rather different considerations.
