Nonnaturalist realism is the view that normative properties are unique kind of stance-independent properties. It has been argued that such views fail to explain why two actions that are exactly alike otherwise must also have the same normative properties. Mark Schroeder and Knut Olav Skarsaune have recently suggested that nonnaturalist realists can respond to this supervenience challenge by taking the primary bearers of normative properties to be action kinds. This paper develops their response in two ways. First, it provides additional (...) motivation for the previous claim about the bearers of normative properties by drawing from the work of H. A. Prichard. Second, and more importantly, it formulates a plausible metaphysical framework based on the contemporary trope theory to explain why action kinds would have their second-order properties, including their normative properties, necessarily.

Stance-independent nonnaturalist moral realism is subject to two related epistemological objections. First, there is the metaethical descendant of the Benacerraf problem. Second, there are evolutionary debunking arguments. Standard attempts to solve these epistemological problems have not appealed to any particular moral epistemology. The focus on these epistemologically neutral responses leaves many interesting theoretical stones unturned. Exploring the ability of particular theories in moral epistemology to handle these difficult epistemological objections can help illuminate strengths or weaknesses within these (...) theories themselves, as well as opening up potentially unexplored avenues for responding to deeply entrenched concerns about our epistemic access to the moral properties. In this paper, I assess the prospects of an empiricist and perceptualist model of moral knowledge for responding to epistemological arguments against non-skeptical moral realism. I argue that such a view has powerful responses to these objections that are not open to other moral epistemologists. The upshot is that if some version of the view is correct, then the realist has less to fear from Benacerraf and evolutionary debunking–style epistemological objections. Insofar as one is already a committed realist, then, this provides some indirect support for moral perceptualism. (shrink)

The Projectability Challenge states that a metaethical view must explain how ordinary agents can, on the basis of moral experience and reflection, accurately and justifiably apply moral concepts to novel situations. In this paper, we argue for two primary claims. First, paradigm nonnaturalism can satisfactorily answer the projectability challenge. Second, it is unclear whether there is a version of moral naturalism that can satisfactorily answer the challenge. The conclusion we draw is that there is an important (...) respect in which nonnaturalism holds an advantage over its most prominent naturalist rivals. The conclusion is interesting if only because it is widely assumed that naturalism has an easier time handling thorny problems in moral epistemology. We argue that there is at least one such problem of which this assumption is not true. (shrink)

It has seemed, to many, that there is an important connection between the ways in which some theoretical posits explain our observations, and our reasons for being ontologically committed to those posits. One way to spell out this connection is in terms of what has become known as the explanatory criterion of ontological commitment. This is, roughly, the view that we ought to posit only those entities that are indispensable to our best explanations. Our primary aim is to argue that (...) the moral nonnaturalist places herself in an invidious position if she simply accepts that the nonnatural moral facts that she posits are not explanatory. Instead, we offer the nonnaturalist an alternative strategy for dealing with moral explanations. The strategy is to retain the explanatory criterion of ontological commitment and maintain that moral properties are, in fact, explanatory. The explanations they provide are not causal explanations; instead, moral properties make a non-causal difference to the physical facts. (shrink)

The Reliability Challenge to moral non-naturalism has received substantial attention recently in the literature on moral epistemology. While the popularity of this particular challenge is a recent development, the challenge has a long history, as the form of this challenge can be traced back to a skeptical challenge in the philosophy of mathematics raised by Paul Benacerraf. The current Reliability Challenge is widely regarded as the most sophisticated way to develop this skeptical line of thinking, making the Reliability (...) Challenge the strongest epistemic challenge to normative nonnaturalism. In this paper, I argue that the innovations that have occurred since Benacerraf’s statement of the challenge are misconceived and confused in a number of ways. The Reliability Challenge is not the most potent epistemic challenge to moral non-naturalism. The most potent challenge comes from the fact that there is a causal condition on knowledge – or, more precisely, a becaual condition – that non-natural moral facts cannot satisfy. (shrink)

I evaluate the metaphysical plausibility of the non-naturalist view of moral properties. I will mainly concentrate my evaluation on the views of Shafer-Landau (henceforth just S-L) whose defence of moral non-naturalism is the most lucid and vigorous so far. I shall try to show its metaphysical problems and defend Jackson’s Occamist naturalism about moral properties which I consider to be more consistent with the supervenience platitude.

Sharon Street’s 2006 article “A Darwinian Dilemma for Realist Theories of Value” challenges the epistemological pretensions of the moral realist, of the nonnaturalist in particular. Given that “Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes” – why should one suppose such attitudes and concomitant beliefs would track an independent moral reality? Especially since, on a nonnaturalist view, moral truth is causally inert. I abstract a logical skeleton of Street’s argument and, (...) with its aid, focus on problematic assumptions regarding the (a)causality of moral truth. It emerges that there are acquired causal powers that compensate for the intrinsic impotence of moral truth, as well as two distinct levels at which truth-tracking might occur. I argue that while evolution’s selective forces do not track moral truth, that does not imply individual organisms could not have evolved that capability. -/- . (shrink)

In his highly engaging book, Speech and Morality, Terence Cuneo advances a transcendental argument for moral realism from the fact that we speak. After summarizing the major moves in the book, I argue that its master argument is not as friendly to non-naturalist versions of moral realism as Cuneo advertises and relies on a diet of insufficient types of speech acts. I also argue that expressivists have compelling replies to each of Cuneo's objections individually, but taken together, Cuneo's (...) objections provide the resources for issuing a new and interesting challenge to expressivists.

In this module I set out the Moral Non-Naturalism of Pūrva Mīmāṃsā as a version of Deontology that defines duty in terms of its beneficent properties. It elucidates the scheme of right living according to ordinance or command. Whereas natural accounts of moral terms suffer from circularity (by merely re-naming of a natural property with a moral term, which then serves to justify its moral appraisal), proponents of Mīmāṃsā defend their position by offering the Vedas as (...) constituting independent evidence about what yields goodness. In some ways, the argument provided by the defenders of Mīmāṃsā prefigure Moore's complaint of the Naturalistic Fallacy, but the Mīmāṃsā approach doesn't claim that defining natural properties by ethical terms is a fallacy: it is simply circular.

In his recent book Error Theory: History, Critique, Defence, Jonas Olson attempts to revive the argument from queerness originally made famous by J.L. Mackie. In this paper, we do three things. First, we eliminate four untenable formulations of the argument. Second, we argue that the most plausible formulation is one that depends crucially upon considerations of parsimony. Finally, we evaluate this formulation of the argument. We conclude that it is unproblematic for proponents of moral non-naturalism—the target of the argument (...) from queerness. (shrink)

Non-naturalist realists are committed to the belief, famously voiced by Parfit, that if there are no non-natural facts then nothing matters. But it is morally objectionable to conditionalise all our moral commitments on the question of whether there are non-natural facts. Non-natural facts are causally inefficacious, and so make no difference to the world of our experience. And to be a realist about such facts is to hold that they are mind-independent. It is compatible with our experiences that there (...) are no non-natural facts, or that they are very different from what we think. As Nagel says, realism makes scepticism intelligible. So the non-naturalist must hold that you might be wrong that your partner matters, even if you are correct about every natural, causal fact about your history and relationship. But to hold that conditional attitude to your partner would be a moral betrayal. So believing non-naturalist realism involves doing something immoral. (shrink)

Analytic reductivism in metaethics has long been out of philosophical vogue. In Confusion of Tongues: A Theory of Normativity (2014), Stephen Finlay tries to resuscitate it by developing an analytic metaethical reductive naturalistic semantics for ‘good.’ He argues that an end-relational semantics is the simplest account that can explain all of the data concerning the term, and hence the most plausible theory of it. I argue that there are several assumptions that a reductive naturalist would need to make about contextual (...) parameter completion to derive reductive naturalism from an end-relational semantics—assumptions that nonnaturalists might forcefully resist. I also argue for the claim that an end-relational semantics could provide surprising resources for nonnaturalists to address semantic worries about their views—the upshot of which paints the way for a new and sophisticated nonnaturalism about the semantics of moral discourse. Nonnaturalists have long suspected that they need not worry about semantics and this paper lends support to that suspicion. (shrink)

On one way of talking about a traditional metaethical topic, realists accept that some items appear on the list of what exists in the moral or more broadly normative domain of inquiry. They then divide over whether those items are like what science and experience suggest that all other items on the list of what exists across all domains are like – naturalistic and secular. Reductive naturalists answer this further question affirmatively. Why don’t nonnaturalists? I explore the answer that (...) it’s because normative entities are “just too different” in the sense that they are countably different things. However, I argue that this answer rests on the subtle presupposition that the normative domain doesn’t also contain uncountable entities of the sort that analytic metaphysicians call “stuff”. Taking intuitions of difference seriously points the way to a novel form of metaethical reductive naturalism. The key is to identify the stuff that matters. (shrink)

This paper investigates whether different philosophers’ claims about “normativity” are about the same subject or (as recently argued by Derek Parfit) theorists who appear to disagree are really using the term with different meanings, in order to cast disambiguating light on the debates over at least the nature, existence, extension, and analyzability of normativity. While I suggest the term may be multiply ambiguous, I also find reasons for optimism about a common subject-matter for metanormative theory. This is supported partly by (...) sketching a special kind of hybrid view of normative judgment, perspectivism, that occupies a position between cognitivism and noncognitivism, naturalism and nonnaturalism, objectivism and subjectivism, making it more plausible that radically different metanormative theories could be about the same thing. I explore three main fissures: between (i) the “normativity” of language/thought versus that of facts and properties, (ii) abstract versus substantive senses, and (iii) formal versus robust senses.

The Duhem-Quine thesis famously holds that a single hypothesis cannot be confirmed or disconfirmed in isolation, but instead only in conjunction with other background hypotheses. This article argues that this has important and underappreciated implications for metaethics. Section 1 argues that if one begins metaethics firmly wedded to a naturalistic worldview—due (e.g.) to methodological/epistemic considerations—then normativity will appear to be reducible to a set of social-psycho-semantic behaviors that I call the ‘normative stance.’ Contra Hume and Bedke (2012), I argue that (...) the normative stance provides semantically-grounded entailments from natural truths to normative truths, reducing the latter to the former. Specifically, the normative stance explains the truth-conditions, truth-values, and truth-makers of normative propositions in terms of socially grounded cognitive-behavioral rules and other natural facts, thus explaining how there can be bona fide normative facts and properties in a wholly naturalistic world. I then show that the normative stance explains the apparent stance-independence and non-naturalness of normative reasons, intrinsic value, and categoricity of moral reasons as ‘user-illusions’ generated by people having strong psycho-social propensities—rooted in evolution and social cooperation—to take these normative stances. Section 2 then argues that while the normative stance may appear to naturalists to successfully explain normativity, it will not appeal to those who come to metaethics with different background commitments. I conclude that naturalists should take the normative stance to be a promising metaethical theory of normativity, and that whether it is a true theory of normativity is something that can only be ascertained by determining which background hypotheses—naturalistic or otherwise—we should have when doing metaethics. (shrink)

Metaethical non-analytical naturalism consists in the metaphysical thesis that normative properties are identical with or reducible to natural properties and the epistemological thesis that we cannot come to a complete understanding of the nature of normative properties via conceptual analysis alone. In On What Matters, Derek Parfit (2011) argues that non-analytical naturalism is either false or incoherent. In § 1, I show that his argument for this claim is unsuccessful, by showing that it rests on a tacit assumption about the (...) nature of normative thought that non-analytical naturalists need not accept. In § 2, I show that escaping Parfit’s argument in this way is no ad hoc maneuver; as I demonstrate, the idea that non-analytical naturalists can exploit to escape Parfit’s argument is a familiar one.

I present here a case against the evidentialist approach that claims that in so far as our interests are epistemic what should guide our belief formation and revision is always a strict adherence to the available evidence. I go on to make the stronger claim that some beliefs based on admittedly “insufficient” evidence may exhibit epistemic virtue. I propose that we consider a form of courage to be an intellectual or epistemic virtue. It is through this notion of courage that (...) we can see a weakness in the evidentialist position. Adopting a doxastically courageous approach allows us to acknowledge the role that evidence has in epistemic justification and its connection with promoting epistemic value, but it avoids the narrowness of an evidentialist position. The epistemically courageous agent is not one who disregards the evidence entirely, but she also realizes that taking risks will not necessarily keep her from her epistemic goals. Believing something in the face of insufficient evidence is not always an epistemic vice to be avoided, and the agent that recognizes this is better off for it. (shrink)

When a circular coin is rotated in depth, is there any sense in which it comes to resemble an ellipse? While this question is at the center of a rich and divided philosophical tradition (with some scholars answering affirmatively and some negatively), Morales et al. (2020, 2021) took an empirical approach, reporting 10 experiments whose results favor such perspectival similarity. Recently, Burge and Burge (2022) offered a vigorous critique of this work, objecting to its approach and conclusions on both philosophical (...) and empirical grounds. Here, we answer these objections on both fronts. We show that Burge and Burge’s critique rests on misunderstandings of Morales et al.’s claims; of the relation between the data and conclusions; and of the philosophical context in which the work appears. Specifically, Burge and Burge attribute to us a much stronger (and stranger) view than we hold, involving the introduction of “a new entity” located “in some intermediate position(s) between the distal shape and the retinal image.” We do not hold this view. Indeed, once properly understood, most of Burge and Burge’s objections favor Morales et al.’s claims rather than oppose them. Finally, we discuss several questions that remain unanswered, and reflect on a productive path forward on these issues of foundational scientific and philosophical interest. (shrink)

En el presente estudio participaron 270 estudiantes en dos muestras; la primera con alumnos de bachillerato, la segunda con alumnos universitarios, ambos del estado de Puebla, México. La investigación fue básicamente cuantitativa, sin embargo, el instrumento utilizado permitió obtener valiosa información cualitativa. El objetivo fue contrastar los resultados históricos de test con dilemas morales clásicos. Los participantes se enfrentaron al Dilema del tranvía, al Dilema de la pasarela y al Dilema de Sofía. Los resultados demostraron que es válida la categorización (...) en cuatro posturas morales básicas: utilitarismo, emotivismo, deontología y ética de la virtud. Y si bien se obtuvieron, en una primera instancia, resultados cuantitativos catalogados como mayormente utilitarios, lo cierto es que las creencias morales exhibidas en el estudio superan el dualismo utilitarismo-emotivismo de estudios previos consultados. In the present study, 270 students participated in two samples, the first with high school students, the second with university students, both from the state of Puebla. The research was quantitative, however, the instrument used allowed obtaining valuable qualitative information. The objective was to contrast the historical test results with classic moral dilemmas. Participants faced the Trolley Dilemma, Footbridge Dilemma and Sophia’s Dilemma. The results showed that the categorization in four basic moral positions is valid: utilitarianism, emotivism, deontology and virtue ethics. And although quantitative results cataloged as mostly utilitarian were obtained in the first instance, the truth is that the moral beliefs exhibited in the study surpass the utilitarianism-emotivism dualism of previous studies consulted.

Arguably the most foundational principle in perception research is that our experience of the world goes beyond the retinal image; we perceive the distal environment itself, not the proximal stimulation it causes. Shape may be the paradigm case of such “unconscious inference”: When a coin is rotated in depth, we infer the circular object it truly is, discarding the perspectival ellipse projected on our eyes. But is this really the fate of such perspectival shapes? Or does a tilted coin retain (...) an elliptical appearance even when we know it’s circular? This question has generated heated debate from Locke and Hume to the present; but whereas extant arguments rely primarily on introspection, this problem is also open to empirical test. If tilted coins bear a representational similarity to elliptical objects, then a circular coin should, when rotated, impair search for a distal ellipse. Here, nine experiments demonstrate that this is so, suggesting that perspectival shapes persist in the mind far longer than traditionally assumed. Subjects saw search arrays of three-dimensional “coins,” and simply had to locate a distally elliptical coin. Surprisingly, rotated circular coins slowed search for elliptical targets, even when subjects clearly knew the rotated coins were circular. This pattern arose with static and dynamic cues, couldn’t be explained by strategic responding or unfamiliarity, generalized across shape classes, and occurred even with sustained viewing. Finally, these effects extended beyond artificial displays to real-world objects viewed in naturalistic, full-cue conditions. We conclude that objects have a remarkably persistent dual character: their objective shape “out there,” and their perspectival shape “from here.”. (shrink)

Our pains can be more or less intense, our mental imagery can be more or less vivid, our perceptual experiences can be more or less striking. These degrees of intensity of conscious experiences are all manifestations of a phenomenal property I call mental strength. In this article, I argue that mental strength is a domain-general phenomenal magnitude; in other words, it is a phenomenal quantity shared by all conscious experiences that explains their degree of felt intensity. Mental strength has been (...) largely overlooked in favor of mental states’ type, representational contents, domain-specific phenomenology, or processes such as attention. Considering mental strength in our reflections about the mind illuminates debates about the relation of representational contents and phenomenal character, and it also helps address questions about the structure and functions of consciousness. Mental strength provides a unifying construct to model what is shared in the phenomenology of different types of conscious experiences. (shrink)

Introspection is a fundamental part of our mental lives. Nevertheless, its reliability and its underlying cognitive architecture have been widely disputed. Here, I propose a principled way to model introspection. By using time-tested principles from signal detection theory (SDT) and extrapolating them from perception to introspection, I offer a new framework for an introspective signal detection theory (iSDT). In SDT, the reliability of perceptual judgments is a function of the strength of an internal perceptual response (signal- to-noise ratio) which is, (...) to a large extent, driven by the intensity of the stimulus. In parallel to perception, iSDT models the reliability of introspective judgments as a function of the strength of an internal introspective response (signal-to-noise ratio) which is, to a large extent, driven by the intensity of conscious experiences. Thus, by modelling introspection after perception, iSDT can calibrate introspection’s reliability across a whole range of contexts. iSDT offers a novel, illuminating way of thinking about introspection and the cognitive processes that support it.

In this chapter, we discuss a selection of current views of the neural correlates of consciousness (NCC). We focus on the different predictions they make, in particular with respect to the role of prefrontal cortex (PFC) during visual experiences, which is an area of critical interest and some source of contention. Our discussion of these views focuses on the level of functional anatomy, rather than at the neuronal circuitry level. We take this approach because we currently understand more about experimental (...) evidence at this coarse level and because these results are appropriate for arbitrating between current theoretical frameworks. We discuss the Two-Visual-Systems Hypothesis (Milner & Goodale 1995; 2006), Local Recurrency (Lamme 2010; Lamme 2006), Higher Order (Lau 2008; Lau & Rosenthal 2011) and Global Workspace theories (Baars 1997; Baars 2005; Dehaene & Naccache 2001; Dehaene 2014). Despite the apparent stark differences between conscious and unconscious perceptual processing, available evidence suggests that their neural substrates must be largely shared. This indicates that the difference in neural activity between conscious and unconscious perceptual processing is likely to be subtle and highly specialized. We argue that current experimental evidence about the involvement of specific activity in prefrontal cortex supports the higher order neural theory of consciousness. In consequence, imaging techniques that focus only on marked differences between conscious and unconscious level of activity are likely to be insensitive to the relevant neural activity patterns that underlie conscious experiences. Finally, it follows from the evidence we discuss that the functional advantages of conscious over unconscious perceptual processing may be more limited than commonly thought. (shrink)

Metacognition is the capacity to evaluate the success of one's own cognitive processes in various domains; for example, memory and perception. It remains controversial whether metacognition relies on a domain-general resource that is applied to different tasks or if self-evaluative processes are domain specific. Here, we investigated this issue directly by examining the neural substrates engaged when metacognitive judgments were made by human participants of both sexes during perceptual and memory tasks matched for stimulus and performance characteristics. By comparing patterns (...) of fMRI activity while subjects evaluated their performance, we revealed both domain-specific and domain-general metacognitive representations. Multivoxel activity patterns in anterior prefrontal cortex predicted levels of confidence in a domain-specific fashion, whereas domain-general signals predicting confidence and accuracy were found in a widespread network in the frontal and posterior midline. The demonstration of domain-specific metacognitive representations suggests the presence of a content-rich mechanism available to introspection and cognitive control. (shrink)

In this paper I argue that many scholars involved in the contemporary free will debates have underappreciated the philosophical appeal of agent causation because the resources of contemporary emergentism have not been adequately introduced into the discussion. Whereas I agree that agent causation’s main problem has to do with its intelligibility, particularly with respect to the issue of how substances can be causally relevant, I argue that the notion of substance causation can be clearly articulated from an emergentist framework. According (...) to my proposal, a free agent is _a causally powerful substance that emerges in an anomic way from her constitutive mental events_, downwardly constraining, selecting and, in this way, having control on them. As we shall see, this particular concept of agent causation not only makes sense of the deep insight behind agent libertarianism, but it also provides us with the resources to solve some of the main objections that have been raised against it. It is true that here I cannot develop a complete defense of the evidential credentials of emergentism. Still, even if the considerations that follow do not serve to convince detractors of agent causal libertarian accounts of free will, they do suggest that libertarian agent causation is more promising than is typically acknowledged.

Consciousness and confidence seem intimately related. Accordingly, some researchers use confidence ratings as a measure of, or proxy for, consciousness. Rosenthal discusses the potential connections between the two, and rejects confidence as a valid measure of consciousness. He argues that there are better alternatives to get at conscious experiences such as direct subjective reports of awareness (i.e. subjects’ reports of perceiving something or of the degree of visibility of a stimulus). In this chapter, we offer a different perspective. Confidence ratings (...) in general, and metacognitive measures in particular, may offer important advantages over subjective ratings. The arguments we offer here are supported by empirical, practical and socio-strategic considerations. However, we do not suggest consciousness and confidence are interchangeable. We recognize the limitations of confidence ratings in some experimental designs and for some research questions. Nevertheless, we also address a potential conceptual link between consciousness and confidence that stems from Rosenthal’s very own work on mental quality space theory. (shrink)

Definiciones de epistemología hay muchas, al igual que clases y estilos. Sin embargo, más allá de esta diversidad, es necesario contar con una definición básica que guíe nuestra comprensión del tema. Dos serán las preguntas que nos ayuden a ello en este artículo: a) ¿qué es la epistemología? y b) ¿para qué le sirve al científico?

Studying the neural correlates of conscious awareness depends on a reliable comparison between activations associated with awareness and unawareness. One particularly difficult confound to remove is task performance capacity, i.e. the difference in performance between the conditions of interest. While ideally task performance capacity should be matched across different conditions, this is difficult to achieve experimentally. However, differences in performance could theoretically be corrected for mathematically. One such proposal is found in a recent paper by Lamy, Salti and Bar-Haim [Lamy (...) D, Salti M, Bar-Haim Y. Neural correlates of subjective awareness and unconscious processing: an ERP study. J Cognitive Neurosci 2009,21:1435-46], who put forward a corrective method for an electroencephalography experiment. We argue that their analysis is essentially grounded in a version of High Threshold Theory, which has been shown to be inferior in general to Signal Detection Theory. We show through a series of computer simulations that their correction method only partially removes the influence of perfor- mance capacity, which can yield misleading results. We present a mathematical correction method based on Signal Detection Theory that is theoretically capable of removing performance capacity confounds. We discuss the limitations of mathemati- cally correcting for performance capacity confounds in imaging studies and its impact for theories about consciousness. (shrink)

To find the neural substrates of consciousness, researchers compare subjects’ neural activity when they are aware of stimuli against neural activity when they are not aware. Ideally, to guarantee that the neural substrates of consciousness—and nothing but the neural substrates of consciousness—are isolated, the only difference between these two contrast conditions should be conscious awareness. Nevertheless, in practice, it is quite challenging to eliminate confounds and irrelevant differences between conscious and unconscious conditions. In particular, there is an often-neglected confound that (...) is crucial to eliminate from neuroimaging studies: task performance. Unless subjects’ task performance is matched (and hence perceptual signal processing is matched), researchers risk finding the neural correlates of perception, rather than conscious perception. Here, we discuss the theoretical motivations for the performance matching framework and review empirical demonstrations of, and theoretical inferences derived from, obtaining differences in consciousness while controlling for task performance. We summarize signal detection theoretic modeling frameworks that explain how it is that we can derive performance-matched differences in consciousness without the effect being trivially driven by differences in criterion setting, and also provide principles for designing experimental paradigms that yield performance-matched differences in awareness. Finally, we address potential technical and theoretical issues that stem from matching performance across conditions of awareness, and we introduce the notion of “triangulation” for designing comprehensive experimental sets that can better reveal the neural substrates of consciousness.

This paper defends doubts about the existence of genuine moral perception, understood as the claim that at least some moral properties figure in the contents of perceptual experience. Standard examples of moral perception are better explained as transitions in thought whose degree of psychological immediacy varies with how readily non-moral perceptual inputs, jointly with the subject's background moral beliefs, training, and habituation, trigger the kinds of phenomenological responses that moral agents are normally disposed to (...) have when they represent things as being morally a certain way.

When visual attention is directed away from a stimulus, neural processing is weak and strength and precision of sensory data decreases. From a computational perspective, in such situations observers should give more weight to prior expectations in order to behave optimally during a discrimination task. Here we test a signal detection theoretic model that counter-intuitively predicts subjects will do just the opposite in a discrimination task with two stimuli, one attended and one unattended: when subjects are probed to discriminate the (...) unattended stimulus, they rely less on prior information about the probed stimulus’ identity. The model is in part inspired by recent findings that attention reduces trial-by-trial variability of the neuronal population response and that they use a common criterion for attended and unattended trials. In five different visual discrimination experiments, when attention was directed away from the target stimulus, subjects did not adjust their response bias in reaction to a change in stimulus presentation frequency despite being fully informed and despite the presence of performance feedback and monetary and social incentives. This indicates that subjects did not rely more on the priors under conditions of inattention as would be predicted by a Bayes-optimal observer model. These results inform and constrain future models of Bayesian inference in the human brain. (shrink)

Counterpossibles, counterfactuals conditional with impossible antecedents, are notoriously contested; while the standard view makes them trivially true, some authors argue that they can be non-trivially true. In this paper, I examine the use of counterfactuals in the context of games, and argue that there is a case to be made for their non-triviality in a restricted sense. In particular, I examine the case of retro problems in chess, where it can happen that one is tasked with evaluating counterfactuals about illegal (...) positions. If we understand illegality as a type of restricted impossibility, those counterfactuals are non-trivial counterpossibles. I suggest that their non-triviality stems from their role in practices of rule coordination and revision, and suggest that this model could be generalized to counterpossibles in different domains. I then compare the approach to the accounts of Vetter 2016 and Locke 2019. (shrink)

Para favorecer la interacción disciplinar y recuperar la dimensión práctica del conocimiento matemático en la escuela secundaria, Yves Chevallard plantea la necesidad de introducir en los programas de estudio la matemática mixta. La matemática mixta, cuyo apogeo tuvo lugar en Europa entre los siglos XVI y XVIII, se propone el abordaje de problemas surgidos por fuera de la propia matemática valiéndose de nociones mecánicas -como la de centro de gravedad y fuerza centrífuga- y del empleo de variados instrumentos para realizar (...) las construcciones requeridas. En este trabajo consideramos a la matemática mixta en la cultura matemática de la segunda mitad del siglo XVII y, en dicho contexto, presentamos dos casos de la práctica matemática de G. W. Leibniz en los que la investigación matemática involucra el diseño de máquinas. La consideración de tales casos permite situar a la matemática mixta, siguiendo la terminología de Ian Hacking, en un terreno medio entre representar e intervenir. El terreno medio entre representar e intervenir es un valle fértil donde la matemática aporta a, y se nutre de, una multiplicidad de otros dominios. También es una vía de acceso para historizar el conocimiento matemático, destacando las condiciones materiales para su desarrollo y el importante rol de los problemas.

We offer a relatively simple and straightforward argument that each of us ought to be vegan. We don’t defend this position by appealing to ‘animal rights’ or the view that animals and humans are ‘moral equals’. Rather, we argue that animal agriculture causes serious harms to other animals (such as pain, suffering and death) and these harms are morally unjustified or caused for no good reason. This is true for both ‘factory farming’ and smaller, so-called ‘humane’ farms. We argue (...) that attempts to justify these harms don’t succeed, and conclude that raising and killing animals for food is wrong. -/- In the second part of our essay we explain how this argument relates to the choices of individuals to buy and consume animal products. Since most people don’t raise and kill animals themselves, the argument above doesn’t directly address individuals’ daily choices. To address this concern, we offer a plausible, general moral principle that describes when consumers should not purchase or consume a product: most simply, we should not support those who act wrongly by seriously harming others, provided we can safely and easily do so. Since, for most people, it is safe and relatively easy to not support those who do wrong by raising and killing animals so they can be eaten, we should not buy or consume animal food products. -/- After making our case that we ought to be vegan, we respond to some of the more challenging objections to our argument. We argue that these objections don’t succeed and so, given our previous argument, nearly everyone is morally obligated to eat a vegan diet. (shrink)

A recent fMRI study by Webb et al. (Cortical networks involved in visual awareness independent of visual attention, Proc Natl Acad Sci U S A 2016;113:13923–28) proposes a new method for finding the neural correlates of awareness by matching atten- tion across awareness conditions. The experimental design, however, seems at odds with known features of attention. We highlight logical and methodological points that are critical when trying to disentangle attention and awareness.

While examining the important role of imagination in making moral judgments, John Dewey and Moral Imagination focuses new attention on the relationship between American pragmatism and ethics. Steven Fesmire takes up threads of Dewey's thought that have been largely unexplored and elaborates pragmatism's distinctive contribution to understandings of moral experience, inquiry, and judgment. Building on two Deweyan notions—that moral character, belief, and reasoning are part of a social and historical context and that moral deliberation is (...) an imaginative, dramatic rehearsal of possibilities—Fesmire shows that moral imagination can be conceived as a process of aesthetic perception and artistic creativity. Fesmire's original readings of Dewey shed new light on the imaginative process, human emotional make-up and expression, and the nature of moral judgment. This original book presents a robust and distinctly pragmatic approach to ethics, politics, moral education, and moral conduct. [The downloadable sample is Chapter Seven, "The Moral Artist."].

In this paper, we explore how a conversational theory of moral responsibility can provide illuminating resources for building a theory about the nature and norms of moral forgiveness.

We accomplish three things in this paper. First, we provide evidence that the motivational internalism/externalism debate in moral psychology could be a false dichotomy born of ambiguity. Second, we provide further evidence for a crucial distinction between two different categories of belief in folk psychology: thick belief and thin belief. Third, we demonstrate how careful attention to deep features of folk psychology can help diagnose and defuse seemingly intractable philosophical disagreement in metaethics.

Should the existence of moral disagreement reduce one’s confidence in one’s moral judgments? Many have claimed that it should not. They claim that we should be morally self-sufficient: that one’s moral judgment and moral confidence ought to be determined entirely one’s own reasoning. Others’ moral beliefs ought not impact one’s own in any way. I claim that moral self-sufficiency is wrong. Moral self-sufficiency ignores the degree to which moral judgment is a fallible (...) cognitive process like all the rest. In this paper, I take up two possible routes to moral self-sufficiency.First, I consider Robert Paul Wolff’s argument that an autonomous being is required to act from his own reasoning. Does Wolff’s argument yield moral self-sufficiency? Wolff’s argument does forbid unthinking obedience. But it does not forbid guidance: the use of moral testimony to glean evidence about nonmoral states of affairs. An agent can use the existence of agreement or disagreement as evidence concerning the reliability of their own cognitive abilities, which is entirely nonmoral information. Corroboration and discorroboration yields nonmoral evidence, and no reasonable theory of autonomy can forbid the use of nonmoral evidence. In fact, by using others to check on my own cognitive functionality, an agent is reasoning better and is thereby more autonomous.Second, I consider Philip Nickel’s requirement that moral judgment proceed from personal understanding. I argue that the requirement of understanding does forbid unthinking obedience, but not discorroboration. When an agent reasons morally, and then reduces confidence in their judgments through discorroboration, they are in full contact with the moral reasons, and with the epistemic reasons. Discorroboration yields more understanding, not less. (shrink)

I argue that a parental prerogative to sometimes prioritize the interests of one’s children over the interests of others is insufficient to make the parental refusal of routine childhood vaccines morally permissible. This is because the moral permissibility of vaccine refusal follows from such a parental prerogative only if the only (weighty) moral reason in favor of vaccination is that vaccination is a means for promoting the interests of others. However, there are two additional weighty moral reasons (...) in favor of routine vaccination: fairness and concern for the vulnerable. These moral reasons in favor of vaccination are not defeated by a parental prerogative to prioritize the interests of one’s children over the interests of others. (shrink)

Stephenson (2022) has argued that Kant’s thesis that all transcendental truths are transcendentally a priori knowable leads to omniscience of all transcendental truths. His arguments depend on luminosity principles and closure principles for transcendental knowability. We will argue that one pair of a luminosity and a closure principle should not be used, because the closure principle is too strong, while the other pair of a luminosity and a closure principle should not be used, because the luminosity principle is too strong. (...) Stephenson’s argument also depends on a factivity principle for transcendental knowability, which we will argue to be false. (shrink)

In this paper, I reject that animal reasoning, negation in particular, necessarily involves the representation of absences, as suggested by Bermúdez (2003, 2006, 2007), since this would still work as a logical negation (unavailable for non-linguistic creatures). False belief, pretense, and communication experiments show that non-human animals (at least some primates) have difficulties representing absent entities or properties. I offer an alternative account resorting to the sub-symbolic similarity judgments proposed by Vigo & Allen (2009) and expectations: animal proto-negation takes place (...) through the incompatibility between an expected and the actual representation. Finally, I propose that the expectation paradigm be extrapolated to other experi-ments in cognitive psychology (both with pre-linguistic children and animals) in order to design fair experiments that test other minds considering their true abilities.

Whether the prefrontal cortex is part of the neural substrates of consciousness is currently debated. Against prefrontal theories of consciousness, many have argued that neural activity in the prefrontal cortex does not correlate with consciousness but with subjective reports. We defend prefrontal theories of consciousness against this argument. We surmise that the requirement for reports is not a satisfying explanation of the difference in neural activity between conscious and unconscious trials, and that prefrontal theories of consciousness come out of this (...) debate unscathed.

A number of philosophers working in applied ethics and bioethics are now earnestly debating the ethics of what they term “moral bioenhancement.” I argue that the society-wide program of biological manipulations required to achieve the purported goals of moral bioenhancement would necessarily implicate the state in a controversial moral perfectionism. Moreover, the prospect of being able to reliably identify some people as, by biological constitution, significantly and consistently more moral than others would seem to pose a (...) profound challenge to egalitarian social and political ideals. Even if moral bioenhancement should ultimately prove to be impossible, there is a chance that a bogus science of bioenhancement would lead to arbitrary inequalities in access to political power or facilitate the unjust rule of authoritarians; in the meantime, the debate about the ethics of moral bioenhancement risks reinvigorating dangerous ideas about the extent of natural inequality in the possession of the moral faculties.

This work proposes that pain meets the requirements of being characterized as a secondary quality, as it covers, like a color, a determined extension. The argument seeks to establish a literal pain-color analogy through an inquiry into the intensity and location of the pain. From the classic intensity/location relationship reported by patients with acute appendicitis, three degrees of pain are distinguished: mild, moderate, and severe. The objective is only achieved by examining the Body’s extensional determinations (primary quality) insofar as each (...) of these degrees of pain covers three particular measures. Once these three measures have been explored according to the perforation process (tissue damage), the work ends by identifying pain as a transcendent moment. (shrink)

The essay argues that while there is no general agreement on whether moral realism is true, there is general agreement on at least some of the moral obligations that we have if moral realism is true. Given that moral realism might be true, and given that we know some of the things we ought to do if it is true, we have a reason to do those things. Furthermore, this reason is itself an objective moral (...) reason. Thus, if moral realism might be true, then it is true. (shrink)

Perception is our primary means of accessing the external world. What is the nature of this core mental process? Although this question is at the center of scientific research on perception, it has also long been explored by philosophers, who ask fundamental questions about our capacity to perceive: Do our different senses represent the world in commensurable ways? How much of our environment can we be aware of at one time? Which aspects of perception are ‘objective’, and which ‘subjective’? What (...) properties count as perceptual in the first place? Although these parallel research programs typically proceed independently in contemporary scholarship, previous eras recognized more active collaboration and interaction across philosophical and scientific approaches to perception. Here, we review an emerging research focus that has begun to reunite these approaches, by putting several long-standing philosophical questions to empirical test. Unlike more general sources of philosophical inspiration, the work described here draws a direct line from a prominent philosophical conjecture or thought experiment about perception to a key test of that question in the laboratory—such that the relevant experimental work would not (and even could not) have proceeded as it did without the preceding philosophical discussion. Finally, we explore themes arising from these successful interactions, and point to further philosophical questions that might be amenable to empirical approaches. (shrink)

The book intends to interpret how different religions articulate their territories and manage the relationship with other religions, understanding systems and multiple everyday spaces, in a dynamic that is not only a component of contemporary reality, but is central to living it. The underlying thesis is that religion is the great geopolitical issue of our time, but an interpretation is only possible in terms of religious plurality and how ideas, symbolism, subjectivities and practices are incorporated in the daily life of (...) those who share the religious times and spaces, producing territorial identities and imaginary concrete cartographies as world projects. The volume has articles that focus on the religious space being gestated, expanded, contracted, celebrated or represented as a foundation for common life, as well as inter-religious conflicts arising in a world of diverse and differential coexistence. It is not a debate about classical geopolitics, but how geopolitical relations cross cultural-religious experience. (shrink)
