In C. S. Lewis’s Christian Apologetics: Pro and Con, I took the con in a debate with Victor Reppert about the soundness of Lewis’s famous “argument from reason.” Reppert then extended his argument in an article for Philosophia Christi; this article is my reply. I show that Reppert’s argument fails for three reasons. (1) It “loads the die” by falsely assuming that naturalism, by definition, can't include mental causation "on the basic level." (I provide multiple examples (...) of naturalist theories of mind that do exactly that). (2) Physical processes can reliably produce true beliefs. And (3) reasoning isn’t necessarily mental.

The “problem of memory” in epistemology is concerned with whether and how we could have knowledge, or at least justification, for trusting our apparent memories. I defend an inductive solution—more precisely, an abductive solution—to the problem. A natural worry is that any such solution would be circular, for it would have to depend on memory. I argue that belief in the reliability of memory can be justified from the armchair, without relying on memory. The justification is, roughly, that (...) my having the sort of experience that my apparent memory should lead me to expect is best explained by the hypothesis that my memories are reliable. My solution is inspired by Harrod’s (1942) inductive solution. Coburn (1960) argued that Harrod’s solution contains a fatal flaw. I show that my solution is not vulnerable to Coburn’s objection, and respond to a number of other, recent and likely objections. (shrink)

The anti-realist argument from underconsideration focuses on the fact that, when scientists evaluate theories, they only ever consider a subset of the theories that can account for the available data. As a result, when scientists judge one theory to be superior to competitor theories, they are not warranted in drawing the conclusion that the superior theory is likely true with respect to what it says about unobservable entities and processes. I defend the argument from underconsideration (...) class='Hi'>from the objections of Peter Lipton. I argue that the inconsistency that Lipton claims to find in the argument vanishes once we understand what the anti-realist means when she claims that scientists are reliable. I also argue that collapsing the distinction between relative and absolute evaluations, as Lipton recommends, has its costs. Finally, I briefly examine Richard Boyd's influential defence of realism.

Heightened awareness of the origins of our moral judgments pushes many in the direction of moral skepticism, in the direction of thinking we are unjustified in holding our moral judgments on a realist understanding of the moral truths. A classic debunking argument fleshes out this worry: the best explanation of our moral judgments does not appeal to their truth, so we are unjustified in holding our moral judgments. But it is unclear how to get from the explanatory premise (...) to the debunking conclusion. This paper shows how to get from here to there by way of epistemic insensitivity. First, we reconstruct Richard Joyce’s evolutionary debunking argument from insensitivity. Second, we raise epistemological difficulties for Joyce’s argument. Third, we develop and defend a new debunking argument from insensitivity. (shrink)

There is a tendency to use data from neuroscience, cognitive science and experimental psychology to rail against philosophical ethics. Recently, Joshua Greene has argued that deontological judgments tend to be supported by emotional responses to irrelevant features, whereas consequentialist judgments are more reliable because they tend to be supported by cognitive processes. In this article, I will analyse the evidence used by Greene to suggest a different kind of argument against deontology, which I will call the argument (...) from self-defeating beliefs. The charge of this type of argument amounts to exposing a psychological nature of deontological judgements that is supposedly rejected by deontologists. I will argue that the alleged evidence is poorly understood, mixed and indeterminate, failing to endorse general conclusions about the psychological processes underlying deontological judgements.

While courts depend on expert opinions in reaching sound judgments, the role of the expert witness in legal proceedings is associated with a litany of problems. Perhaps most prevalent is the question of under what circumstances should testimony be admitted as expert opinion. We review the changing policies adopted by American courts in an attempt to ensure the reliability and usefulness of the scientific and technical information admitted as evidence. We argue that these admissibility criteria are best seen in (...) a dialectical context as a set of critical questions of the kind commonly used in models of argumentation. (shrink)

Arguments from "easy knowledge" are meant to refute a class of epistemological views, including foundationalism about perceptual knowledge. I present arguments from easy knowledge in their strongest form, and explain why other formulations in the literature are inferior. I criticize two features of Stewart Cohen's presentation, namely his focus on knowing that one's faculties are reliable, and his use of a Williamson-style closure principle. Rather, the issue around easy knowledge must be understood using a notion of epistemic priority. (...) Roger White's presentation is contaminated by the so-called lottery puzzle, which is best kept separate. Distinguishing basic from non-basic visual contents limits the force of the examples discussed by Cohen, White, and Crispin Wright. Finally, I present a new strategy for resisting even the best-formulated arguments from easy knowledge. (shrink)

In recent years, a new argument in favor of Donnellan’s (Philos Rev 77: 281–304, 1966) semantic distinction between attributive and referential descriptions has been proposed by Michael Devitt and Marga Reimer. This argument is based on two empirical premises concerning regularity of use and processing ease. This paper is an attempt to demonstrate (a) that these empirical observations are dubious and fail to license the conclusion of the argument and (b) that if the argument were sound, (...) it would severely overgenerate. The general lesson of the paper is that empirical observations about (a) how frequent an expression E is used to mean M and (b) how easy and fast M is processed cannot be taken to provide reliable evidence about the lexically encoded semantic properties of E.

Jesper Ahlin Marceta published an article in this journal in which he formulated his “argument from testability”, stating that it is impossible, at least practically, to operationalize procedural authenticity. That is, using procedural accounts of authenticity, one cannot reliably differentiate between authentic and inauthentic desires. There are roughly two ways to respond to the argument from testability: top-down and bottom-up. Several authors have endeavored the top-down approach by trying to show that some conceptions of authenticity might (...) be operationalizable after all. At present, however, the bottom-up approach has not been put to the test. That is, no attempt has been made to use a currently existing assessment tool to guide the development of an account of authenticity. In this paper, I will investigate what it means to develop an account of authenticity bottom-up based on measures of concordance. More specifically, I will investigate the following three research questions. First, how do concordance and authenticity relate at a conceptual level? As crucial similarities exist between these concepts, concordance measures seem to offer a good starting point for the bottom-up approach. Second, how do judgements of concordance differ from judgements of authenticity? Both their scope and the way they are justified will turn out to be different. This suggests novel ways to react to Marceta’s argument from testability. Third, should we develop a theory of concordance? The positive answer to this question will point towards a central limitation of the bottom-up approach. (shrink)

This article seeks, first, to show that much of the existing normative work on argument from expert opinion (AEO) is problematic for failing to be properly informed by empirical findings on expert performance. Second, it seeks to show how, with the analytic tool of Bayesian reasoning, the problem diagnosed can be remedied to circumvent some of the problems facing the scheme-based treatment of AEOs. To establish the first contention, we will illustrate how empirical studies on factors conditioning expert (...) reliability can be drawn upon to re-construct. Walton’s critical questions matching the scheme of AEOs. To establish the second contention, we will illustrate how Walton’s re-constructed set of critical questions can be formalized within a Bayesian network. Finally, we will highlight how the specific ways in which the Bayesian framework we propose is both continuous with and distinct from the models of source reliability put forward by theorists like Bovens and Hartmann (2003).

Occasionally, in the introductory philosophy courses I teach, a student will give an interesting argument for non-belief in God. Though I have never seen this argument in print, it seems familiar. Basically, the argument goes like this. Religious belief is largely determined by geography – where you are born and raised largely determines your religious beliefs. But believing something just because of where you are born and raised is not a reliable indication of whether that belief turns (...) out to be true. So, in some sense, you are not justified in your religious beliefs. I will attempt a more rigorous reconstruction of this argument and offer an objection to it. (shrink)

Locke clearly intends what I call his 'linguistic thesis,' the claim that words signify nothing but ideas, to tell against Aristotelian essentialism. I argue that current interpretations of Locke's anti-essentialist arguments have not accorded the linguistic thesis its proper role. This is largely due to the prevalent misreadings of that thesis. Locke's view is that words reliably indicate ideas in the mind of the speaker. It is only once we see this that we can understand how the thesis functions in (...) Locke's anti-Aristotelian project.

In his article “Constructive Empiricism Now” van Fraassen chooses an extremely interesting example to defend his thesis that scientific theories are only representations, so that the aim of science is to give us reliable, empirically adequate, descriptions of the observable aspects of the world. For him, there is no continuum of observable/unobservable, as he draws a line of distinction at a point that eliminates from his ontology such cases as fields of forces and sub-atomic particles. As a result, he (...) puts forward the position that electronic images in the microscope and subatomic particles are “public hallucinations” and not “real things”. What I thus propose to do is to examine van Fraassen’s anti-realism through the looking class of realism, my aim being to defend a realist view of science: To this purpose, I will focus on two main issues: (a) the question of representations in science and in particular of images we “see” through a microscope and (b) the question of the criteria for defining physical reality. In this context, I will argue that van Fraassen’s definition of the “real” is an anti-realist version of the positivist trend, which cannot fit in the picture of science that emerges today. To understand, thus, the world of physics we need to re-examine our definition of reality and make space for an ontology that goes beyond the well-defined spatio-temporal existence of what van Fraassen calls a “real thing”.

After a brief outline of Enoch’s defense of robust realism in his Taking Morality Seriously, I focus on Enoch’s taking-morality-seriously thought by making explicit the assumptions I see involved in it. Enoch’s argument from impartiality is then reconstructed to show how these assumptions are at work. Next, I explain the reasons why Enoch does not succeed in converting these assumptions into a positive argument for the thesis implied by robust realism that there is a moral objectivity. Finally, (...) I conclude that the critical analysis provided casts a shadow on the reliability of the taking-morality-seriously thought as a basis of a theoretical inquiry into the nature of morality. (shrink)

A recent study of moral intuitions, performed by Joshua Greene and a group of researchers at Princeton University, has recently received a lot of attention. Greene and his collaborators designed a set of experiments in which subjects were undergoing brain scanning as they were asked to respond to various practical dilemmas. They found that contemplation of some of these cases (cases where the subjects had to imagine that they must use some direct form of violence) elicited greater activity in certain (...) areas of the brain associated with emotions compared with the other cases. It has been argued (e.g., by Peter Singer) that these results undermine the reliability of our moral intuitions, and therefore provide an objection to methods of moral reasoning that presuppose that they carry an evidential weight (such as the idea of reflective equilibrium). I distinguish between two ways in which Greene's findings lend support for a sceptical attitude towards intuitions. I argue that, given the first version of the challenge, the method of reflective equilibrium can easily accommodate the findings. As for the second version of the challenge, I argue that it does not so much pose a threat specifically to the method of reflective equilibrium but to the idea that moral claims can be justified through rational argumentation in general.

Recent debate in metaethics over evolutionary debunking arguments against morality has shown a tendency to abstract away from relevant empirical detail. Here, I engage the debate about Darwinian debunking of morality with relevant empirical issues. I present four conditions that must be met in order for it to be reasonable to expect an evolved cognitive faculty to be reliable: the environment, information, error, and tracking conditions. I then argue that these conditions are not met in the case of our (...) evolved faculty for moral judgement. (shrink)

A tempting argument for human rationality goes like this: it is more conducive to survival to have true beliefs than false beliefs, so it is more conducive to survival to use reliable belief-forming strategies than unreliable ones. But reliable strategies are rational strategies, so there is a selective advantage to using rational strategies. Since we have evolved, we must use rational strategies. In this paper I argue that some criticisms of this argument offered by Stephen Stich fail because (...) they rely on unsubstantiated interpretations of some results from experimental psychology. I raise two objections to the argument: (i) even if it is advantageous to use rational strategies, it does not follow that we actually use them; and (ii) natural selection need not favor only or even primarily reliable belief-forming strategies.

In this paper, I argue that causal theories of memory are typically committed to two independent, non-mutually entailing theses. The first thesis pertains to the necessity of appropriate causation in memory, specifying a condition token memories need to satisfy. The second pertains to the explanation of memory reliability in causal terms and it concerns memory as a type of mental state. Post-causal theories of memory can reject only the first (weak post-causalism) or both (strong post-causalism) theses. Upon this backdrop, (...) I examine Werning’s (2020) causalist argument from probabilistic correlation. I argue that it doesn’t establish the necessity of appropriate causation and thus it can only target strong post-causalist theories. I end up by presenting some general considerations, suggesting that memories may not always be causally linked to past experiences. (shrink)

In recent years, the epistemic reliability of moral intuitions has been undermined by substantial empirical data reporting the influence of cognitive biases. This paper discusses and elaborates upon a promising strategy in response to the reliability challenge to moral intuitions. The argument considered appeals to the fact that moral intuitions come in different levels of strength and agents accept only strong intuitions, not vulnerable to bias under realistic circumstances. This essay aims to reconstruct the defense from (...) the reliability challenge in its most promising form and to evaluate the plausibility of the argument in light of the available empirical evidence. What will emerge from the discussion is that the vindication of moral intuitions fundamentally depends on two distinct premises: first, the hypothesis that agents accept moral intuitions proportionally to their level of confidence, and second, the hypothesis that intuitive confidence is epistemically reliable. Whereas there is consistent evidence for the first hypothesis, there is still no conclusive evidence for the second. (shrink)

Bodily sensations, such as pain, hunger, itches, or sexual feelings, are commonly characterized in terms of their phenomenal character. In order to account for this phenomenal character, many philosophers adopt strong representationalism. According to this view, bodily sensations are essentially and entirely determined by an intentional content related to particular conditions of the body. For example, pain would be nothing more than the representation of actual or potential tissue damage. In order to motivate and justify their view, strong representationalists often (...) appeal to the reliable causal covariance between bodily sensations and certain kinds of bodily conditions or to the corresponding biological function that these bodily sensations are supposed to fulfill. In this paper, I argue on the basis of recent empirical research that arguments from reliable causal covariance and biological function cannot motivate the introduction of corresponding intentional content. In particular, I argue that bodily sensations are caused by a heterogeneous class of physiological and psychological factors and their biological functions are too diverse to be reduced to the representation of a particular bodily condition. Responses are available to strong representationalists, but they either require substantial alterations to their core assumptions or incur a significant empirical burden. (shrink)

Are we entitled or justified in taking the word of others at face value? An affirmative answer to this question is associated with the views of Thomas Reid. Recently, C. A. J. Coady has defended a Reidian view in his impressive and influential book. Testimony: A Philosophical Study. His central and most Oliginal argument for his positions involves reflection upon the practice of giving and accepting reports, of making assertions and relying on the word of others. His argument (...) purports to show that testimony is, by its very nature, a “reliable form of evidence about the way the world is.” The argument moves from what we do to why we are justified in doing it. Although I am sympathetic with both the Reidian view and Coady’s attempt to connect why we rely on others with why we are entitled to rely on others, I find Coady’s argument ineffective. (shrink)

Although there exist today a variety of non-deductive reliable processes able to determine the truth of certain mathematical propositions, proof remains the only form of justification accepted in mathematical practice. Some philosophers and mathematicians have contested this commonly accepted epistemic superiority of proof on the ground that mathematicians are fallible: when the deductive method is carried out by a fallible agent, then it comes with its own level of reliability, and so might happen to be equally or even less (...) reliable than existing non-deductive reliable processes—I will refer to this as the reliability argument. The aim of this article is to examine whether the reliability argument forces us to reconsider the commonly accepted epistemic superiority of the deductive method over non-deductive reliable processes. I will argue that the reliability argument is fundamentally correct, but that there is another epistemic property differentiating the deductive method from non-deductive reliable processes. This property is based on the observation that although mathematicians are fallible agents, they are also self-correcting agents. This means that when a proof is produced that only contains repairable mistakes, given enough time and energy, a mathematician or a group thereof should be able to converge towards a correct proof through a finite number of verification and correction rounds, thus providing a guarantee that the considered proposition is true, something that non-deductive reliable processes will never be able to produce. From this perspective, the standard of justification adopted in mathematical practice should be read in a diachronic way: the demand is not that any proof that is ever produced be correct—which would amount to requiring that mathematicians are infallible—but rather that, over time, proofs that contain repairable mistakes be corrected, and proofs that cannot be repaired be rejected.

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.

Kant famously made a distinction between actions from duty and actions in conformity with duty claiming that only the former are morally worthy. Kant’s argument in support of this thesis is taken to rest on the claim that only the motive of duty leads non-accidentally or reliably to moral actions. However, many critics of Kant have claimed that other motives such as sympathy and benevolence can also lead to moral actions reliably, and that Kant’s thesis is false. In (...) addition, many readers of Kant find the claim that we should deny moral worth to a dutiful action performed from friendly inclination highly counterintuitive. Moreover, Kantian commentators disagree about the status of actions in conformity with duty, some claim that these can be taken as equally morally worthy as those performed from duty, while others argue that they are not even permissible. -/- It has also been claimed that Kant’s theory of moral worth should be related to the theory of the Gesinnung developed in the Religion. Thus, some authors claim that, in order for an action to possess moral worth, the agent has to be unconditionally committed to morality, that is, the agent must possess a virtuous character or good fundamental maxim (i.e. a good Gesinnung). However, according to Kant’s radical evil thesis (that is, the thesis that man is evil by nature ), the default position for man is to possess an evil Gesinnung, i.e. a Gesinnung which is only conditionally committed to morality insofar as morality does not demand a great sacrifice of our own happiness. So, an unwelcome consequence of this line of interpretation is that in Kantian ethics morally worthy actions become very rare indeed. -/- The paper is divided in two parts. The first part aims to clarify why Kant thought that only actions from duty are morally worthy, replying to some common objections against Kant’s view. I argue that Kant’s non-accidental condition should not be understood in terms of reliability because such interpretation is incompatible with Kant’s theory of motivation and rational agency. I propose an alternative interpretation which supports Kant’ s claim that only the motive of duty leads nonaccidently to dutiful actions, and thus only actions from duty possess moral worth. I end by showing that although actions in conformity with duty are worthless from the moral point of view, they are not (in many cases) impermissible. The first part concludes that the criterion for the permissibility of actions is different to the criterion for the ascription of moral worth. Thus, rightness, which pertains to actions performed on maxims that can be willed as universal laws, and moral worth, which pertains to actions performed from a sense of duty, should be understood as two different levels of moral assessment. -/- The second part of the paper examines Kant’s conception of virtue with the aim of showing that although only agents with a virtuous character (good Gesinnung) will reliably act from duty, a person with an evil character (evil Gesinnung) could on frequent occasions act from duty. I argue that we should not deny moral worth to actions performed from duty even when the agent has an evil Gesinnung. Goodness of Gesinnung is not a necessary condition of the action of an agent possessing moral worth; reliability of motivation is necessary for the ascription of virtue but not for the ascription of moral worth. It follows that virtue, which refers to the agent’s character or fundamental maxim (i.e. the agent’s Gesinnung), and moral worth are also two different levels of moral assessment. The paper concludes that three levels of moral assessment can be distinguished in Kant’s ethical system: (i) rightness, (ii) moral worth and (iii) moral virtue. Moral virtue is the highest level of moral perfection for a human being. Striving towards virtue requires constant progress and effort and ultimately a ‘revolution of the heart.’ The important point is that even when we are still striving to achieve virtue (i.e. an unconditional commitment to morality), we can ascribe moral worth to actions performed by a genuine sense of duty. It turns out that, contrary to many influential interpretations, Kantian ethics is not merely concerned with the rightness or wrongness of particular actions nor is Kantian ethics primarily an ethic of virtue. Instead, Kant’s ethical system is complex and allows for different levels of moral assessment in which both an action-centred and agent-centred perspective can be integrated. (shrink)

Debunking arguments—also known as etiological arguments, genealogical arguments, access problems, isolation objec- tions, and reliability challenges—arise in philosophical debates about a diverse range of topics, including causation, chance, color, consciousness, epistemic reasons, free will, grounding, laws of nature, logic, mathematics, modality, morality, natural kinds, ordinary objects, religion, and time. What unifies the arguments is the transition from a premise about what does or doesn't explain why we have certain mental states to a negative assessment of their epistemic status. (...) I examine the common, underlying structure of the arguments and the different strategies for motivating and resisting the premises of debunking arguments. (shrink)

Hans Reichenbach is well known for his limiting frequency view of probability, with his most thorough account given in The Theory of Probability in 1935/1949. Perhaps less known are Reichenbach's early views on probability and its epistemology. In his doctoral thesis from 1915, Reichenbach espouses a Kantian view of probability, where the convergence limit of an empirical frequency distribution is guaranteed to exist thanks to the synthetic a priori principle of lawful distribution. Reichenbach claims to have given a purely (...) objective account of probability, while integrating the concept into a more general philosophical and epistemological framework. A brief synopsis of Reichenbach's thesis and a critical analysis of the problematic steps of his argument will show that the roots of many of his most influential insights on probability and causality can be found in this early work.

Argument schemes are abstractions substantiating the inferential connection between premise(s) and conclusion in argumentative communication. Identifying such conventional patterns of reasoning is essential to the interpretation and evaluation of argumentation. Whether studying argumentation from a theory-driven or data-driven perspective, insight into the actual use of argumentation in communicative practice is essential. Large and reliably annotated corpora of argumentative discourse to quantitatively provide such insight are few and far between. This is all the more true for argument scheme (...) corpora, which tend to suffer from a combination of limited size, poor validation, and the use of ad hoc restricted typologies. In the current paper, we describe the annotation of schemes on the basis of two distinct classifications: Walton’s taxonomy of argument schemes, and Wagemans’ Periodic Table of Arguments. We describe the annotation procedure for each, and the quantitative characteristics of the resulting annotated text corpora. In doing so, we extend the annotation of the preexisting US2016 corpus of televised election debates, resulting in, to the best of our knowledge, the two largest consistently annotated corpora of schemes in argumentative dialogue publicly available. Based on evaluation in terms of inter-annotator agreement, we propose further improvements to the guidelines for annotating schemes: the argument scheme key, and the Argument Type Identification Procedure.

Despite the long history of scientific, philosophical, and political debate around heritability studies, certain fundamental conceptual issues have not been recognized or well appreciated. The starting point is that heritability does not measure the degree of influence that genes have on a trait or provide a reliable basis for choosing which traits to investigate further with molecular genetic research. The short argument on this point revolves around two issues: the disconnect between analyzing measurements of a trait and exposing the (...) measurable genetic and environmental factors underlying the trait’s development; and the possibility of heterogeneity in these underlying factors, that is, different factors may lead to the same trait value. The idea of underlying heterogeneity is elaborated through schematic diagrams and distinguished from other senses of heterogeneity. Five conceptually distinct approaches for addressing underlying heterogeneity are identified, corresponding to distinct ways of managing the reciprocal relationship between the degree of knowledge of the dynamics through which the trait develops and the actions that can be reliably be based on what is known . This framework, which extends the interventionist notion of causality, allows the scope and limitations of heritability studies to be clarified in greater detail. It can also inform critical appreciation of newer methods of analysis of genetic and environmental factors. The issues discussed in this article do not centre on empirical data or technical detail and should be accessible to non-specialists as well as challenging active researchers. (shrink)

In evaluating science, philosophers tends to focus on general laws and on their truth. I urge a shift in focus to the reliability of the panoply of outputs science produces and in tandem, from the general to the particular. Here I give five arguments to support this, including many, many scientific outputs, which must be supposed reliable if we are to warrant our general principles, aren’t truth-apt; and reliability invites the crucial question, ‘Reliable for what?’ Getting clear (...) the particular purpose is essential for effective action and just evaluation.

Reliable misrepresentation is getting things wrong in the same way all the time. In Mendelovici 2013, I argue that tracking theories of mental representation cannot allow for certain kinds of reliable misrepresentation, and that this is a problem for those views. Artiga 2013 defends teleosemantics from this argument. He agrees with Mendelovici 2013 that teleosemantics cannot account for clean cases of reliable misrepresentation, but argues that this is not a problem for the views. This paper clarifies and improves (...) the argument in Mendelovici 2013 and response to Artiga's arguments. Tracking theories, teleosemantics included, really do need to allow for clean cases of reliable misrepresentation. (shrink)

Suppose that there are objective normative facts and our beliefs about such facts are by-and-large true. How did this come to happen? This is the reliability challenge to normative realism. As has been recently noted, the challenge also applies to expressivist “quasi-realism”. I argue that expressivism is useful in the face of this challenge, in a way that has not been yet properly articulated. In dealing with epistemological issues, quasi-realists typically invoke the desire-like nature of normative judgments. However, this (...) is not enough to prevent the reliability challenge from arising, given that quasi-realists also hold that normative judgments are truth-apt beliefs. To defuse this challenge, we need to isolate a deeper sense in which normative thought is not representational. I propose that we rely on the negative functional thesis of expressivism: normative thought does not have the function of tracking normative facts, or any other kind of facts. This thesis supports an argument to the effect that it is misguided to expect an explanation of our access to normative facts akin to the explanations available in regions of thought that have a tracking function. We should be content with explanations of our reliability that take for granted certain connections between our psychology and the normative truths. (shrink)

There is an ancient, yet still lively, debate in moral epistemology about the epistemic significance of disagreement. One of the important questions in that debate is whether, and to what extent, the prevalence and persistence of disagreement between our moral intuitions causes problems for those who seek to rely on intuitions in order to make moral decisions, issue moral judgments, and craft moral theories. Meanwhile, in general epistemology, there is a relatively young, and very lively, debate about the epistemic significance (...) of disagreement. A central question in that debate concerns peer disagreement: When I am confronted with an epistemic peer with whom I disagree, how should my confidence in my beliefs change (if at all)? The disagreement debate in moral epistemology has not been brought into much contact with the disagreement debate in general epistemology (though McGrath [2007] is an important exception). A purpose of this paper is to increase the area of contact between these two debates. In Section 1, I try to clarify the question I want to ask in this paper – this is the question whether we have any reasons to believe what I shall call “anti-intuitivism.” In Section 2, I argue that anti-intuitivism cannot be supported solely by investigating the mechanisms that produce our intuitions. In Section 3, I discuss an anti-intuitivist argument from disagreement which relies on the so-called “Equal Weight View.” In Section 4, I pause to clarify the notion of epistemic parity and to explain how it ought to be understood in the epistemology of moral intuition. In Section 5, I return to the anti-intuitivist argument from disagreement and explain how an apparently-vulnerable premise of that argument may be quite resilient. In Section 6, I introduce a novel objection against the Equal Weight View in order to show how I think we can successfully resist the anti-intuitivist argument from disagreement. (shrink)

This volume represents a contribution to the philosophy of economics with a distinctive point of view -- the contributors have selected particular areas of economics and have probed these areas for the philosophical and methodological issues that they raise. The primary essays are written by philosophers concentrating on philosophical issues that arise at the level of the everyday theoretical practice of working economists. Commentary essays are provided by working economists responding to the philosophical arguments from the standpoint of their (...) own disciplines. The volume thus represents something of an `experiment' in the philosophy of science, striving as it does to explore methodological issues across two research communities. The purpose of the volume is very specific: to stimulate a discussion of the epistemology and methodology of economics that works at the level of detail of existing `best practice' in economics today. The contributors have designed their contributions to stimulate productive conversation between philosophers and economists on topics in the methodology of economics. (shrink)

Combining testimonial reports from independent and partially reliable information sources is an important epistemological problem of uncertain reasoning. Within the framework of Dempster–Shafer theory, we propose a general model of partially reliable sources, which includes several previously known results as special cases. The paper reproduces these results on the basis of a comprehensive model taxonomy. This gives a number of new insights and thereby contributes to a better understanding of this important application of reasoning with uncertain and incomplete information.

Matthew Braddock’s argument from false god beliefs (AFG) is one of the most significant debunking arguments to emerge from the growing literature on Cognitive Science of Religion (CSR). This argument aims to produce a defeater for any basic theistic belief. In this essay, I reply to AFG by defending a counter-example to AFG’s crucial premise. In particular, I argue that the cognitive mechanisms posited by CSR do not “significantly contribute” to perceptually based theistic belief formation in (...) the way that AFG claims. As a result, a large class of basic theistic beliefs remains undefeated in the face of AFG. (shrink)

Philosophers of memory have approached the relationship between memory and imagination from two very different perspectives. Advocates of the causal theory of memory, on the one hand, have motivated their preferred theory by appealing to the intuitive contrast between successfully remembering an event and merely imagining it. Advocates of the simulation theory, on the other hand, have motivated their preferred theory by appealing to empirical evidence for important similarities between remembering the past and imagining the future. Recently, causalists have (...) argued that simulationism is unable to accommodate the difference between successful remembering and forms of unsuccessful remembering or mere imagining such as confabulating. This paper argues that, while these arguments fail, simulationism, in its current form, is indeed unable to provide a fully adequate account of unsuccessful remembering. Rather than suggesting a return to causalism, the paper proposes a new form of simulationism, a virtue theory of memory modelled not on the process reliabilist epistemology that has so far served as the inspiration for the simulation theory but instead on virtue reliabilist epistemology, and shows that this new theory grounds a more adequate account of unsuccessful remembering.

An important challenge for non-naturalistic moral realism is that it seems hard to reconcile it with the (purported) fact of our reliability in forming correct moral beliefs. Some philosophers (including Cuneo and Shafer-Landau) have argued that we can appeal to conceptual truths about our moral concepts in order to respond to this challenge. Call this “the conceptual strategy”. The conceptual strategy faces a problem: it isn’t clear that the relevant moral concepts are “extension-revealing” in the way that the conceptual (...) strategy needs them to be. A further problem stems from the tradeoff between the “extension-revealing” and the “authority-revealing” aspects of normative concepts. To underscore the import of these issues, I discuss a version of the reliability challenge that concerns authoritative normative facts in ethics (rather than moral facts). The problems I identify for the conceptual strategy carry over to versions of it that are used in response to a range of epistemological arguments in ethics that (like the reliability challenge) are tied to Street’s “Darwinian Dilemma” argument. These problems also bear on the prospects of the conceptual strategy for explaining our (purported) reliability in other domains (e.g., in epistemology, law, and politics). (shrink)

I defend ethical hedonism, the view that pleasure is the sole good thing, by arguing that it offers the only answer to an argument for moral skepticism. The skeptical problem arises from widespread fundamental moral disagreement, which entails the presence of enough moral error to undermine the reliability of most processes generating moral belief. We know that pleasure is good through the reliable process of phenomenal introspection, which reveals what our experiences are like. If knowing of pleasure’s (...) goodness through phenomenal introspection is the only reliable way to form our initial moral beliefs, we should accept ethical hedonism. (shrink)

The idea that fictions may educate us is an old one, as is the view that they distort the truth and mislead us. While there is a long tradition of passionate assertion in this debate, systematic arguments are a recent development, and the idea of empirically testing is particularly novel. Our aim in this chapter is to provide clarity about what is at stake in this debate, what the options are, and how empirical work does or might bear on its (...) resolution. We distinguish between merely influencing people’s opinions and providing genuine learning, where the latter requires that the source of the change in opinion should be reliable. Other important ideas here are the extent to which authors of fiction may be considered to provide testimony, or something like it, and the possibility of recognizing an unstated purpose in the project of the fictional work. We ask whether fictions can furnish us not merely with ideas but with reasons for believing them, perhaps by constituting thought experiments. We consider whether the focus should be on understanding rather than on knowledge, and whether fictions can inform us about the qualities of another’s experiences. We briefly describe some experimental work of recent decades and suggest that the evidence for learning from fiction is currently meagre. (shrink)

The author identifies the structure of Sharon Street's skeptical challenge to non-naturalist, normative epistemic realism as an argument that NNER is liable to reliability defeat and then argues that Street's argument fails, because it itself is subject to reliability defeat. As the author reconstructs Street's argument, it is an argument that the normative epistemic judgments of the realist could only be probabilistically sensitive to normative epistemic truths by sheer chance. The author then recaps Street's (...) own naturalist translation of normative epistemic judgments into purely descriptive, contingent probability statements, and argues that, on her own terms, the reasoning that leads her to rationally believe in evolutionary theory could only be probabilistically sensitive to the relevant purely descriptive, contingent probabilities by sheer chance. The author's argument is addressed to Street, but it applies to all evolutionary naturalist accounts of epistemic rationality. The author explains how his argument differs from Plantinga's Evolutionary Argument Against Naturalism and shows how it avoids the objections to Plantinga's EAAN. The author closes with the outline of an explanation of how evolution could have made human reasoning probabilistically sensitive to metaphysically necessary normative epistemic standards, even though those standards did not exert and, indeed, could not have exerted any kind of causal influence on the evolutionary process.

The article considers John Greco's conception of testimonial knowledge that aims to overthrow three sceptical arguments against religious knowledge. Prof. Greco presupposes that a religious community already possesses a true religious belief and its reliability is justified exclusively by means of the reliability of transmission. The author puts this conception into question and presents some sceptical arguments regarding the initial origination of a religious belief and verifying the truth-ness of a religious belief in front of epistemic disagreement problem. (...) In particular, he draws an attention on three moments: 1) difference between inside and outside position as to any religious community, 2) lack of inductive verifying evidence in support of religious knowledge, and 3) difference between origination a belief in a community for the first time and transmission of beliefs already given in a community. The author takes a perspective of an outsider who doesn't belong to any religious community (on the assumption that there are secular communities different from religious ones). Firstly, he suggests another from Greco's version of the “luck argument", which concerns the luck in origination of a belief, not the accidence in spreading it. John Greco solves a problem that arises from argument of luck as far as it regards transmission of beliefs inside a community. The author argues that the genuine problem is to establish an originating source of a religious belief, and taking that into consideration, testimonial evidence cannot eliminate this kind of luck. Secondly, he observes the problem of disagreement among different religious communities. He shows that an outsider doesn't have any epistemic reason to prefer one of the conflicting religious beliefs of different communities, for he doesn't belong to any of them. Thus, the problem of “epistemic peers" still remains unsolved. (shrink)

Cognitive science of religion has inspired several debunking arguments against theistic belief. Hans Van Eyghen’s book Arguing from Cognitive Science of Religion is the first monograph devoted to answering such arguments. This article focuses on Van Eyghen’s responses to two widely discussed debunking arguments, one by Matthew Braddock and another by John Wilkins and Paul Griffiths. Both responses have potential but also face problems. Even if Van Eyghen manages to show that these authors have not fully excluded the possibility (...) of noninferential theistic belief being underpinned by reliable belief-forming processes, he fails to offer convincing reasons to think the processes are in fact reliable. A positive argument for their reliability might ultimately have to be based on evidence for God’s existence, namely, theistic arguments. The question of the rationality of religious belief (de jure) thus cannot be isolated from the question of God’s existence (de facto). (shrink)

Strong predictivism, the idea that novel predictions per se confirm theories more than accommodations, is based on a “no miracle” argument from novel predictions to the truth of theories (NMAT). Eric Barnes rejects both: he reconstructs the NMAT as seeking an explanation for the entailment relation between a theory and its novel consequences, and argues that it involves a fallacious application of Occam’s razor. However, he accepts a no miracle argument for the truth of background beliefs (NMABB): (...) scientists endorsed a successful theory because they were guided by largely true background beliefs. This in turn raises the probability that the theory is true; so Barnes embraces a form of weak predictivism, according to which predictions are only indirectly relevant to confirmation. To Barnes I reply that we should also explain how the successful theory was constructed, not just endorsed; background beliefs are not enough to explain success, scientific method must also be considered; Barnes can account for some measure of confirmation of our theories, but not for the practical certainty conferred to them by some astonishing predictions; true background beliefs and reliability by themselves cannot explain novel success, the truth of theories is also required. Hence, the NMAT is sound, and strong predictivism is right. In fact, Barnes misinterprets the NMAT, which does not involve Occam’s razor, takes as explanandum the building of a theory which turned out to predict surprising facts, and successfully concludes that the theory is true. This accounts for the practically certain confirmation of our most successful theories, in accordance with strong predictivism. (shrink)

Tribunals have come to depend increasingly on expertise for determining the facts in cases. However, current legal methods have proved problematic to work with. This paper argues that, as a special model of public understanding of science, assessing expertise should consider source credibility of expertise from internal aspects, including scientific validity and reliability, and external aspects involving the credibility of experts. Using the Carneades Argumentation System we show that the internal and the external aspects are mediated by the (...) structure of the argument from expert opinion with its matching set of critical questions.

The main aim of this paper is to revisit the curve fitting problem using the reliability of inductive inference as a primary criterion for the ‘fittest' curve. Viewed from this perspective, it is argued that a crucial concern with the current framework for addressing the curve fitting problem is, on the one hand, the undue influence of the mathematical approximation perspective, and on the other, the insufficient attention paid to the statistical modeling aspects of the problem. Using goodness-of-fit (...) as the primary criterion for ‘best', the mathematical approximation perspective undermines the reliability of inference objective by giving rise to selection rules which pay insufficient attention to ‘accounting for the regularities in the data'. A more appropriate framework is offered by the error-statistical approach, where (i) statistical adequacy provides the criterion for assessing when a curve captures the regularities in the data adequately, and (ii) the relevant error probabilities can be used to assess the reliability of inductive inference. Broadly speaking, the fittest curve (statistically adequate) is not determined by the smallness if its residuals, tempered by simplicity or other pragmatic criteria, but by the nonsystematic (e.g. white noise) nature of its residuals. The advocated error-statistical arguments are illustrated by comparing the Kepler and Ptolemaic models on empirical grounds. ‡I am grateful to Deborah Mayo and Clark Glymour for many valuable suggestions and comments on an earlier draft of the paper; estimating the Ptolemaic model was the result of Glymour's prompting and encouragement. †To contact the author, please write to: Department of Economics, Virginia Tech 3019 Pamplin Hall (0316), Blacksburg, VA 24061; e-mail: [email protected].
