How much should your confidence in your beliefs be shaken when you learn that others – perhaps 'epistemic peers' who seem as well-qualified as you are – hold beliefs contrary to yours? This article describes motivations that push different philosophers towards opposite answers to this question. It identifies a key theoretical principle that divides current writers on the epistemology of disagreement. It then examines arguments bearing on that principle, and on the wider issue. It ends by describing some outstanding questions (...) that thinking about this issue raises. (shrink)

A growing body of empirical literature challenges philosophers’ reliance on intuitions as evidence based on the fact that intuitions vary according to factors such as cultural and educational background, and socio-economic status. Our research extends this challenge, investigating Lehrer’s appeal to the Truetemp Case as evidence against reliabilism. We found that intuitions in response to this case vary according to whether, and which, other thought experiments are considered first. Our results show that compared to subjects who receive the Truetemp Case (...) first, subjects first presented with a clear case of knowledge are less willing to attribute knowledge in the Truetemp Case, and subjects first presented with a clear case of nonknowledge are more willing to attribute knowledge in the Truetemp Case. We contend that this instability undermines the supposed evidential status of these intuitions, such that philosophers who deal in intuitions can no longer rest comfortably in their armchairs.

I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that thedemand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair (...) or question-begging one.

Using empirical evidence to attack intuitions can be epistemically dangerous, because various of the complaints that one might raise against them (e.g., that they are fallible; that we possess no non-circular defense of their reliability) can be raised just as easily against perception itself. But the opponents of intuition wish to challenge intuitions without at the same time challenging the rest of our epistemic apparatus. How might this be done? Let us use the term “hopefulness” to refer to the extent (...) to which we possess a good capacity for the detection and correction of the errors of any fallible source of evidence. I argue that we should not trust putative sources of evidence that are substantially lacking in hopefulness (even if they are basically reliable), and that we are indeed already operating under such a norm in our ordinary and scientific practices. I argue further that the philosophical practice of the appeal to intuitions is, in these terms, badly hopeless... (shrink)

Radical empiricism is the view that a person's experiences (sensory and introspective), or a person's observations, constitute the person's evidence. This view leads to epistemic self-defeat. There are three arguments, concerning respectively: (1) epistemic starting points; (2) epistemic norms; (3) terms of epistemic appraisal. The source of self-defeat is traced to the fact that empiricism does not count a priori intuition as evidence (where a priori intuition is not a form of belief but rather a form of seeming, specifically intellectual (...) as opposed to sensory). Moderate rationalism, by contrast, avoids self-defeat. (shrink)

Conciliationism is the family of views that rationality requires agents to reduce confidence or suspend belief in p when acknowledged epistemic peers (i.e. agents who are (approximately) equally well-informed and intellectually capable) disagree about p. While Conciliationism is prima facie plausible, some have argued that Conciliationism is not an adequate theory of peer disagreement because it is self-undermining. Responses to this challenge can be put into two mutually exclusive and exhaustive groups: the Solution Responses which deny Conciliationism is self-undermining and (...) attempt to provide arguments which demonstrate this; and the Skeptical Responses which accept that Conciliationism is self-undermining but attempt to mitigate this result by arguing this is either impermanent and/or not very worrisome. I argue that, by Conciliationism’s own lights, both kinds of responses (almost certainly) fail to save Conciliationism from being self-undermining. Thus, Conciliationism is (almost certainly) permanently self-undermining. This result is significant because it demonstrates that Conciliationism is likely hopeless: there is likely nothing that can save Conciliationism from this challenge. I further argue that Conciliationism, like any view, should be abandoned if it is (almost certainly) hopeless. (shrink)

Recently John Turri (2015b) has argued, contra the orthodoxy amongst epistemologists, that reliability is not a necessary condition for knowledge. From this result, Turri (2015a, 2017, 2016a, 2019) defends a new account of knowledge - called abilism - that allows for unreliable knowledge. I argue that Turri's arguments fail to establish that unreliable knowledge is possible and argue that Turri's account of knowledge is false because reliability must be a necessary condition for knowledge.

This paper reports the first study in the literature that adopts a bibliometric approach to systematically explore the scholarship in the young and fast‐growing research field of experimental philosophy. Based on a corpus of 1,248 publications in experimental philosophy from the past two decades retrieved from the PhilPapers website, the study examined the publication trend, the influential experimental philosophers, the impactful works, the popular publication venues, and the major research themes in this subarea of philosophy. It found, first, an overall (...) growing trend in publications in experimental philosophy, encompassing four developmental stages. Second, it found that significant changes in topics of interest have taken place, with some gaining increasing attention, others seemingly going out of fashion, and still others remaining popular constantly. Third, the study identified lists of leading philosophers, frequently cited publications, and popular journals helpful for researchers and newcomers to get a quick start in learning about the field.

Machery’s book is an effort to show how experimental philosophy can be valuable without the perephenelia of intuitions. I argue that the effort fails.

It is valuable for inquiry to have researchers who are committed advocates of their own theories. However, in light of pervasive disagreement, such a commitment is not well explained by the idea that researchers believe their theories. Instead, this commitment, the rational attitude to take toward one’s favored theory during the course of inquiry, is what I call endorsement. Endorsement is a doxastic attitude, but one which is governed by a different type of epistemic rationality. This inclusive epistemic rationality is (...) sensitive to reasons beyond those to think the particular proposition in question is true. Instead, it includes extrinsic epistemic reasons, which concern the health of inquiry more generally. Such extrinsic reasons include the distribution of cognitive labor that a researcher will contribute to by endorsing a particular theory. Recognizing endorsement and inclusive epistemic rationality thus allows us to smooth a tension between individual rationality and collective rationality. It does so by showing how it can be epistemically rational to endorse a theory on the basis of the way this endorsement will benefit collective inquiry. I provide a decision theoretic treatment for inclusive epistemic rationality and endorsement which illustrates how this can be accomplished. (shrink)

I recommend three revisions to experimental philosophy's ‘self-image’ which I suggest will enable experimentalist critics of intuition to evade several important objections to the 'negative' strand of the experimental philosophy research project. First, experimentalists should avoid broad criticisms of ‘intuition’ as a whole, instead drawing a variety of conclusions about a variety of much narrower categories of mental state. Second, experimentalists should state said conclusions in terms of epistemic norms particular to philosophical inquiry, rather than attempting to, for example, deny (...) that intuitions produce justified belief. Third, experimentalists should acknowledge the limitations of the ‘method of cases’ model of philosophical inquiry, and expand their experimental work accordingly. (shrink)

Contemporary philosophers nearly unanimously endorse knowledge reliabilism, the view that knowledge must be reliably produced. Leading reliabilists have suggested that reliabilism draws support from patterns in ordinary judgments and intuitions about knowledge, luck, reliability, and counterfactuals. That is, they have suggested a proto-reliabilist hypothesis about “commonsense” or “folk” epistemology. This paper reports nine experimental studies (N = 1262) that test the proto-reliabilist hypothesis by testing four of its principal implications. The main findings are that (a) commonsense fully embraces the possibility (...) of unreliable knowledge, (b) knowledge judgments are surprisingly insensitive to information about reliability, (c) “anti-luck” intuitions about knowledge have nothing to do with reliability specifically, and (d) reliabilists have mischaracterized the intuitive counterfactual properties of knowledge and their relation to reliability. When combined with the weakness of existing arguments for reliabilism and the recent emergence of well supported alternative views that predict the widespread existence of unreliable knowledge, the present findings are the final exhibit in a conclusive case for abandoning reliabilism in epistemology. I introduce an alternative theory of knowledge, abilism, which out-performs reliabilism and well explains all the available evidence. (shrink)

There is a virtual consensus in contemporary epistemology that knowledge must be reliably produced. Everyone, it seems, is a reliabilist about knowledge in that sense. I present and defend two arguments that unreliable knowledge is possible. My first argument proceeds from an observation about the nature of achievements, namely, that achievements can proceed from unreliable abilities. My second argument proceeds from an observation about the epistemic efficacy of explanatory inference, namely, that inference to the best explanation seems to produce knowledge, (...) even if it isn't reliable. I also propose a successor to standard versions of reliabilism, which I call ‘ecumenical reliabilism’. Ecumenical reliabilism is consistent with unreliably produced knowledge and helps explain why unreliably produced knowledge is possible. (shrink)

ABSTRACT In Philosophy Within its Proper Bounds, Édouard Machery argues that the results of experimental philosophy should lead us to abandon much of traditional philosophical practice. In its place Machery defends naturalized conceptual analysis as a more modest and pragmatic alternative to standard analytic philosophy. This paper argues that Machery overstates the metaphilosophical significance of x-phi’s results. We can and should keep many of the insights and good methodological habits that come with x-phi. However, if one is not already convinced (...) of pragmatism or naturalism, the discoveries of x-phi are unlikely to make too much difference to one’s metaphilosophical position. (shrink)

The topic is experimental philosophy as a naturalistic movement, and its bearing on the value of intuitions in philosophy. This paper explores first how the movement might bear on philosophy more generally, and how it might amount to something novel and promising. Then it turns to one accomplishment repeatedly claimed for it already: namely, the discrediting of armchair intuitions as used in philosophy.

I am extremely grateful to Mikio Akagi, Nick Hughes, and Alison Springle for their insightful and challenging comments on Philosophy Within Its Proper Bounds (Machery 2017). In this response, I wil...

Conciliationism is a view—well, a family of views—in the epistemology of disagreement. The idea, simply put, is that, in a wide range of cases where you find yourself in disagreement with another reasoner about the truth of some proposition, you are rationally obliged to adjust your credence in the direction of hers. Conciliationism enjoys a fair bit of prima facie plausibility. Most versions of it, however, suffer from a common (and rather obvious) problem: self-incrimination. Although there is some recognition in (...) the recent literature on disagreement that there is a problem in this vicinity, it, more often than not, is completely ignored. When it is not completely ignored, both the conciliationists and their critics tend to frame the problem incorrectly. As a result, they end up focusing most of their attention on pseudo-problems rather than the genuine worry. Furthermore, even when they have hit on the genuine worry, conciliationists have tended to give surprising and implausible responses to it. Even by their own lights, conciliationists aren’t justified in believing their conciliationist theses. In this paper, I argue that it’s time to come clean. Time to look for a view on the epistemic significance of disagreement that we can actually be justified in believing. (shrink)

ABSTRACT This article argues that the data presented in Philosophy Within Its Proper Bounds are of greater interest to psychologists than to philosophers, and cautions experimental philosophers against some experimental shortcomings in the use of self-report and vignettes.

There is, in my view, a striking combination in Édouard Machery’s Philosophy Within Its Proper Bounds of philosophical modesty and philosophical presumptiveness. Its call upon philosophers to give up their ambitious pursuits of metaphysical necessities, or essences, and to content themselves instead with the elucidation or analysis of our concepts, is made from within a pre-Kantian framework that takes the world expressed in human discourse and captured in our concepts to be a world as it is in itself, altogether independent (...) of how it comes into view in our discursive practices. And this, I will propose, means that Machery’s critique of much of the work that has been carried out within mainstream analytic philosophy in the last few decades, as well as his proposal for philosophical reform, end up partaking in what has been most fundamentally problematic about that work. (shrink)

Edouard Machery argues that many traditional philosophical questions are beyond our capacity to answer. Answering them seems to require using the method of cases, a method that involves testing answers to philosophical questions against what we think about real or imagined cases. The problem, according to Machery, is that this method has proved unreliable ; what we think about these kinds of cases is both problematically heterogeneous and volatile. His bold solution: abandon the method of cases altogether and with it (...) many of the questions that we have come to associate with philosophy itself. Many of the critical responses to Machery’s book have focused on whether empirical work on judgements about philosophical cases supports his claim that the method of cases is unreliable. Our problem with these responses is that they accept that reliability is the right way to frame empirically informed concerns about the method of cases, and we think that it is not. The reason is simple: the kind of unreliability thesis that Machery needs proves to be empirically intractable, at least by anything like the current methods used by experimental philosophers, or so we shall argue here. While we have empirical grounds for thinking that unreliability arguments don’t give us reason to abandon the method of cases, we do think that there are empirical grounds for thinking that it needs to be reformed. There are other standards that we expect our methods to meet beyond mere reliability, especially standards of practical rationality, which are too often forgotten in metaphilosophical discussions that tend to focus exclusively on epistemological considerations. Methodological considerations, after all, are not just matters of epistemic normativity, but practical rationality as well. What’s more, considerations of practical rationality become particularly important when we move from the kind of extreme scepticism that Machery endorses to the kind of progressive reformation that we think should be pursued. And so we conclude by arguing that thinking about philosophical inquiry in terms of standards of practical rationality allows us both to better understand what kinds of problems recent empirical work on philosophical cognition raises for the method of cases and also how that work can point the way to reforming it.
