Mark Murphy argues that the property identity version of divine command theory, coupled with the doctrine that God has freedom in commanding, violates the supervenience of the moral on the nonmoral. In other words, they permit two situations exactly alike in nonmoral facts to differ in moral facts. I give three arguments to show that a divine command theorist of this sort can consistently affirm moral supervenience. Each argument contends that there are always nonmoral differences (...) between worlds with different divine commands. If there are such nonmoral differences, then there’s no conflict between divine command theory and moral supervenience. (shrink)

This paper is a survey of the supervenience challenge to non-naturalist moral realism. I formulate a version of the challenge, consider the most promising non-naturalist replies to it, and suggest that no fully effective reply has yet been given.

Explaining the supervenience of the moral on the natural is, perhaps, the central metaphysical challenge for the non-naturalist. However, Scanlon (2014) and Fogal and Risberg (2020) have developed a strategy which purports to explain supervenience rather simply. Fogal and Risberg call it the 'Divide and Conquer' strategy. The key idea is to postulate explanatory moral principles linking the natural and the moral. The moral principles are metaphysically necessary, so trivially supervene on the natural. All (...) other moral facts are determined by the necessary moral principles and the natural facts, so they supervene on the natural too. -/- I argue that there are two versions of the Divide and Conquer strategy and both fail. The first strategy doesn’t give an adequate explanation of supervenience because it doesn't properly identify what makes a difference to the holding of supervenience. The second perhaps does give an adequate explanation of supervenience, but only by introducing something similarly puzzling that needs explanation. -/- Consequently, non-naturalists need additional metaphysical machinery to develop their view -- just appealing to moral principles or metaphysical laws won't do the job.

Moral particularism, on some interpretations, is committed to a shapeless thesis: the moral is shapeless with respect to the natural. (Call this version of moral particularism ‘shapeless moral particularism’). In more detail, the shapeless thesis is that the actions a moral concept or predicate can be correctly applied to have no natural commonality (or shape) amongst them. Jackson et al. (Ethical particularism and patterns, Oxford University Press, Oxford, 2000) argue, however, that the shapeless thesis violates (...) the platitude ‘predication supervenes on nature’—predicates or concepts apply because of how things are, and therefore ought to be rejected. I defend shapeless moral particularism by arguing that Jackson et al’s contention is less compelling than it firstly appears. My defense is limited in the sense that it does not prove shapeless moral particularism to be right and it leaves open the possibility that shapeless moral particularism might attract criticisms different from the ones advanced by Jackson et al. But at the very least, I hope to say enough to undermine Jackson et al’s powerful attack against it. The plan of this paper is as follows. Section 1 glosses the view of moral particularism and why it is taken to be essentially committed to the shapeless thesis. Section 2 examines a Wittgensteinian argument for the shapeless thesis. I shall argue that the Canberrans’ counter-arguments against it on grounds of disjunctive commonality and conceptual competence do not succeed. Section 3 explicates Canberrans’ predication supervenience argument against the shapeless thesis. Section 4 offers my criticisms of the Canberrans’ predication supervenience argument. In view of the above discussions, in Sect. 5, I conclude that there is no compelling argument (from the Canberrans) to believe that the shapeless thesis fails (as I have argued in Sect. 4). In fact, there is some good reason for us to believe it (as I have argued in Sect. 2). If so, I contend that moral particularism, when construed as essentially committed to the shapeless thesis, still remains as a live option. (shrink)

When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on (...) the natural have also been influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.

I take the debate between the particularists and the principlists to be centered on the issue of whether there are true moral principles. One argument the principlists often appeal to in support of their claim that there are true moral principles is the argument from supervenience. Roughly, the argument is made up of the following three statements: (P1) If the thesis of moral supervenience holds, then there are true moral principles. (P2) The thesis of (...) moral supervenience holds. (C) There are true moral principles, and hence particularism is false. In this paper, I argue that the above argument is not sound by attacking (P1). I hold that no general supervenient/resultance base has a robust enough configuration of contextual features as to ground the existence of true moral principles. If I am right about this, I think it would be indicative of a reason to be less confident about the truth of principlism and more confident about the truth of particularism. (shrink)

Supervenience in metaethics is the notion that there can be no moral dif-ference between two acts, persons or events without some non-moral difference underlying it. If St. Francis is a good man, there could not be a man exactly like St. Francis in non-evaluative respects that is not good. The phenomenon was first systematically discussed by R. M. Hare (1952), who argued that realists about evaluative properties struggle to account for it. As is well established, Hare, and (...) following him, Simon Blackburn, mistakenly took the relevant phenomenon to be weak rather than strong supervenience, and the explanations they offered for it are accordingly outdated. In this paper, I present a non-factualist account of strong su-pervenience of the evaluative and argue that it fares better than compet-ing realist views in explaining the conceptual nature of the phenomenon, as well as in offering an account of the supervenience of the evaluative in general, rather than more narrowly the moral. While Hare and Blackburn were wrong about the specifics, they were right in that non-factualists can offer a plausible account of the supervenience of the evaluative, that in certain respects is superior to competing realist explanations.

One of our most fundamental notions of morality is that in so far as objects have moral properties, they have non-moral properties that make them have moral properties. Similarly, objects have moral properties in virtue of or because of having non-moral properties, and moral properties depend on non-moral properties. In ethics it has generally been assumed that this relation can be accounted for by the supervenience of moral properties on non-moral (...) properties. However, this assumption is put into doubt by an influential view in contemporary ethics: particularism. Thus, one of particularism’s most important implications is thought to be that supervenience is incapable of accounting for the notion that non-moral properties make objects havemoral properties. At least, this iswhat Jonathan Dancy, the leading proponent of particularism, argues in his recent book Ethics Without Principles, and elsewhere. In the present paper, I defend supervenience against this challenge. That is, I argue that particularism does not threaten the ability of supervenience to account for the notion that non-moral properties make objects have moral properties. While doing so, I hope to contribute to our understanding of what is involved in this notion. In the next section, I consider a general argument put forward by Dancy against supervenience and criticize his alternative, resultance. In Section 3, I develop a version of supervenience that I call Specific Moral Supervenience, SMS, and which I think avoids Dancy’s argument. There are basically two conceptions of particularism: what is known as ‘holism’ and the contention that there are no true moral principles. In Section 4, I argue that the view that SMS provides a basis for an account of the notion that non-moral properties make objects have moral properties is compatible with the pertinent version of holism. However, in Section 5 we see that SMS is incompatible with the view that there are no true moral principles. Particularists find support for this view in the distinction between non-moral properties that make objects have moral properties and so-called enablers. On Dancy’s conception of this distinction, it follows that SMS does not refer to non-moral properties that make objects have moral properties and that there are no true moral principles of the relevant kind. In Sections 6 and 7, I defend SMS against these two consequences. In doing so, I distinguish two uses of ‘make’ and provide a pragmatic account of the distinction between non-moral properties that make objects have moral properties and enablers. (shrink)

Non-naturalism – roughly the view that normative properties and facts are sui generis and incompatible with a purely scientific worldview – faces a difficult challenge with regard to explaining why it is that the normative features of things supervene on their natural features. More specifically: non-naturalists have trouble explaining the necessitation relations, whatever they are, that hold between the natural and the normative. My focus is on Stephanie Leary's recent response to the challenge, which offers an attempted non-naturalism-friendly explanation for (...) the supervenience of the normative on the natural by appealing to hybrid properties, the essences of which link them to both natural and sui generis normative properties in suitable ways. I argue that despite its ingenuity, Leary's solution fails. This is so, I claim, because there are no hybrid properties of the sort that her suggestion appeals to. If non-naturalists are to deal with the supervenience challenge, they will have to find another way of doing so. (shrink)

Metaethics is traditionally understood as a non-moral discipline that examines moral judgements from a standpoint outside of ethics. This orthodox understanding has recently come under pressure from anti-Archimedeans, such as Ronald Dworkin and Matthew Kramer, who proclaim that rather than assessing morality from an external perspective, metaethical theses are themselves substantive moral claims. In this paper, I scrutinise this anti-Archimedean challenge as applied to the metaethical position of expressivism. More precisely, I examine the claim that expressivists do (...) not avoid moral commitments when accounting for moral thought, but instead presuppose them; they do not look at ethics from the outside, but operate from within ethics. This paper defends the non-moral status of expressivism against anti-Archimedeanism by rejecting a new anti-Archimedean challenge which, on the basis of Hume’s Law, aims to exploit expressivist explanations of supervenience in order to show that expressivism is a substantive moral position.

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.

In his defence of an error theory for normative judgements, Bart Streumer presents a new 'reduction' argument against nonreductive normative realism. Streumer claims that unlike previous versions, his 'simple moral theory' version of the argument doesn’t rely on the supervenience of the normative on the descriptive. But this is incorrect; without supervenience the argument does not succeed.

In this paper I explore the implications of moral vagueness (viz., the vagueness of moral predicates) for non-naturalist metaethical theories like those recently championed by Shafer-Landau, Parfit, and others. I characterise non-naturalism in terms of its commitment to 7 theses: Cognitivism, Correspondence, Atomism, Objectivism, Supervenience, Non-reductivism, and Rationalism. I start by offering a number of reasons for thinking that moral predicates are vague in the same way in which ‘red’, ‘tall’, and ‘heap’ are said to be. (...) I then argue that the moral non-naturalist seeking to countenance moral vagueness faces a dilemma: are moral properties vague, or perfectly sharp? On either horn of the dilemma, serious problems arise for some of the central tenets of non-naturalism: vague properties seem to threaten Objectivism, Supervenience, and Non-reductivism; on the other hand, sharp properties raise problems for Supervenience and Rationalism. The difficulties on each horn of the dilemma are real, and while they may not be insuperable, they do, at the very least, drastically limit the things non-naturalists can consistently say about moral properties, facts, and reasons.

This paper aims to support the claim that analytic metaphysics should be more cautious regarding the constraints that truthmaking considerations impose on metaphysical theories. To this end, I reply to Briggs and Forbes (2017), whoargue that certain truthmaking commitments are incurred by a Humean metaphysics and by the Growing-Block theory. First, I argue that Humean Supervenience does not need to endorse a standard version of truthmaker maximalism. This undermines Briggs and Forbes’s conclusion that Humean Supervenience and the Growing-Block (...) theory are incompatible. Second, I argue that the Growing-Block theory does not commit us to any weaker version of truthmaker maximalism, which also undermines Briggs and Forbes’s conclusion. Finally, I point out other reasons to think that any version of truthmaker maximalism is disputable, undermining a fortiori Briggs and Forbes’s conclusion and supporting the moral that metaphysical theories—or at least Humean Supervenience, the Growing-Block theory, and presentism—are little constrained by truthmaking commitments.

It’s commonly held that particular moral facts are explained by ‘natural’ or ‘descriptive’ facts, though there’s disagreement over how such explanations work. We defend the view that general moral principles also play a role in explaining particular moral facts. More specifically, we argue that this view best makes sense of some intuitive data points, including the supervenience of the moral upon the natural. We consider two alternative accounts of the nature and structure of moral (...) principles—’the nomic view’ and ‘moral platonism’—before considering in what sense such principles obtain of necessity.

Contrary to popular opinion, non-natural realism can explain both why normative properties supervene on descriptive properties, and why this pattern is analytic. The explanation proceeds by positing a subtle polysemy in normative predicates like “good”. Such predicates express slightly different senses when they are applied to particulars (like Florence Nightingale) and to kinds (like altruism). The former sense, “goodPAR”, can be defined in terms of the latter, “goodKIN”, as follows: x is goodPAR iff there is a kind K such that (...) x is a token of K, and K is goodKIN. Now if x and y are descriptively exactly similar, then they are tokens of exactly the same kinds, so x is a token of a goodKIN kind if and only if y is. Therefore, by the definition, x is goodPAR if and only if y is. Supervenience just falls out of the definition of “goodPAR”. (shrink)

Despite much discussion over the existence of moral facts, metaethicists have largely ignored the related question of their possibility. This paper addresses the issue from the moral error theorist’s perspective, and shows how the arguments that error theorists have produced against the existence of moral facts at this world, if sound, also show that moral facts are impossible, at least at worlds non-morally identical to our own and, on some versions of the error theory, at any (...) world. So error theorists’ arguments warrant a stronger conclusion than has previously been noticed. This may appear to make them vulnerable to counterarguments that take the possibility of moral facts as a premise. However, I show that any such arguments would be question-begging. (shrink)

This paper challenges a widespread, if tacit, assumption of animal ethics, namely, that the only properties of entities that matter to their moral status are intrinsic, cross‐specific properties—typically psychological capacities. According to moral individualism (Rachels 1990; McMahan 2002; 2005), the moral status of an individual, and how to treat him or her, should only be a function of his or her individual properties. I focus on the fundamental assumption of moral individualism, which I call intrinsicalism. On (...) the challenged view, pigs, puppies and babies, insofar as they are intrinsically similar in morally relevant respects are equally deserving of having their interests satisfied (Norcross 2004). Moreover, relationships—merely agent-relative—are assumed to be irrelevant to moral status. I argue that, while some intrinsic properties are indeed fundamentally relevant, the principled exclusion of extrinsic properties (in virtue of extrinsicness) is unwarranted. From uncontroversial assumptions about supervenience, final value, and moral status, I argue for the relevance of extrinsic properties to moral status based on vulnerability and “reasonable partiality”, as illustrated by pet-keeping.

I discuss a strategy for grounding ethical naturalism propounded by Frank Jackson and more recently by Allan Gibbard: that the undisputed supervenience of the moral upon the natural (or descriptive) entails that moral properties are natural (or descriptive) properties. I show that this strategy falls foul of certain indubitable constraints governing natural kinds; and I then rebut some objections. The upshot is that no viable strategy for supporting ethical naturalism is to be found along these lines. This (...) result has additional consequences, both for Jackson's attempt to accommodate ethical discourse into the natural world, and for Gibbard's purported 'meta-ethical synthesis'. (shrink)

In this paper, I motivate skepticism about the causal efficacy of moral properties in two ways. First, I highlight a tension that arises between two claims that moral realists may want to accept. The first claim is that physically indistinguishable things do not differ in any causally efficacious respect. The second claim is that physically indistinguishable things that differ in certain historical respects have different moral properties. The tension arises to the extent to which these different (...) class='Hi'>moral properties are supposed to have different effects on people. I will introduce a class of cases in which this tension arises and suggest that the moral properties in these cases have no causal power. I will also question whether there are differences between the moral properties in these cases and moral properties in other cases that do not involve physically indistinguishable things that could make the latter moral properties causally efficacious. The second way that I motivate skepticism consists in pointing out a unique feature of cases in which moral properties are supposed both to supervene on historical properties and to be causally efficacious. These cases allow us to change moral properties with alleged effects while we hold constant the nonmoral candidates for causal contribution to those effects. This feature of these cases is unique because in most other cases the moral properties supervene on the physical properties in the nonmoral candidates, such that we cannot change the former while holding constant the latter. This way of changing moral properties provides empirical grounds for testing their causal efficacy. (shrink)

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)

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)

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)

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)

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.

In “The Constraints of Hume’s Naturalism” Barry Stroud takes on the task of looking at Hume’s negative and positive accounts of induction in conjunction. Stroud goes about doing this so that we might walk away with “a more general lesson about naturalism, at least when it is indulged in for philosophical purposes”. Given the boldness of Stroud’s quote from above there should be some explicit talk of this general lesson about naturalism outside of Hume’s, but there is none that is (...) readily apparent. If a more general and philosophically motivated lesson about naturalism is to be gleaned from Stroud’s investigation of Hume, then we should take this to be a lesson implicit in Stroud and not Hume. Hence I shall argue that Stroud tacitly endorses the skeptical conclusions of David Hume about naturalism in general when indulged for philosophical purposes. (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 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.

Many philosophical discussions hinge on the concept of knowability. For example, there is a blooming literature on the so-called paradox of knowability. How to understand this notion, however? In this paper, we examine several approaches to the notion: the naive approach to take knowability as the possibility to know, the counterfactual approach endorsed by Edgington (1985) and Schlöder (2019) , approaches based on the notion of a capacity or ability to know (Fara 2010, Humphreys 2011), and finally, approaches that make (...) use of the resources of dynamic epistemic logic (van Benthem 2004, Holliday 2017).

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)

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)

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?

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.

Comenzamos este texto con una pregunta, por algo que podríamos llamar un signo propio de la época, a saber, la proliferación de aproximaciones espaciales a los más diversos problemas y desde las más diversas disciplinas. No podemos dejar de notar que eso, cuyos signos se dejan recoger a pesar de su dispersión, en algo que llamamos época, sobreviene después de un agotamiento de la radicalización del historicismo y de un pensamiento del tiempo.

Darwin’s theory is often illustrated with depictions of different finch beaks or with lined-up skeletons displaying subtle bone-structure changes throughout evolutionary history. In The Deep Histor...

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)

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.

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.

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)

Este ensayo tiene tres pilares sobre los que se asienta. En primer lugar tendremos que especificar y aclarar los conceptos de auctoritas y potestas (Capítulo II)-que se irán desarrollando a lo largo de la misma-en relación con el vocablo poder, ya que estos conceptos tienen una similitud tanto en su etimología como en la forma que posteriormente se han utilizado en el pensamiento político, de forma tal que ha originado equívocos y cambios a la hora de conformar una comunidad legitimante (...) constituida. Para ello se acudirá a pensadores clásicos y contemporáneos que se han preocupado por la exégesis del binomio auctoritas-potestas, en relación a la legitimación del poder. Ello nos permitirá abordar el segundo pilar (Capítulos III, IV), en referencia a la génesis de la época moderna, como cambio de paradigma que dará a los vocablos referenciados una nueva forma de ejercer el poder a la hora de configurar dicha época. Ello se debe al paulatino alejamiento de los sistemas filosóficos de nuestras sociedades occidentales de la religión, la ética y de la metafísica. Por tanto nos acercaremos al surgimiento del cuestionamiento de la época moderna, a partir del nacimiento de la Ilustración como movimiento que cuestiona todo prejuicio que proviene de la religión y de su carácter de autoridad, para desembocar en el surgimiento del Pacto Social, como idea de razón kantiana que alberga el orden político y social de la época moderna. Por último, como tercer pilar, que es trasversal a todos ellos y en continua relación con los dos anteriores estudiaremos las reflexiones de dos pensadores del siglo XX, como son Boaventura de Sousa y Richard Rorty-ya que la maduración y trayectorias intelectuales de sus obras así nos lo aconsejan-, pueden representar dos visiones diferentes de afrontar los retos que se nos presentan en nuestros tiempos, en cuanto a los principios, los valores y la estructura que debería tener una sociedad del siglo XXI, en la que se pueda articular la convivencia de la forma más justa en relación con la auctoritas y la potestas. La elección de los mismos para confrontar sus aportaciones, tanto en el campo epistemológico, ontológico e ideológico, así como en el modelo de sociedad que ellos defienden, se fundamenta en que ambos representan puentes de diálogo posibles tanto entre la filosofía analítica (positivismo) y continental-Richard Rorty-como entre la filosofía europea continental (La teoría crítica de la Escuela de Frankfurt) y la filosofía latinoamericana anticolonial de autores del siglo XX -Boaventura de Sousa-. Esto último nos permitirá adentrarnos en la discusión entre modernidad y postmodernidad (Capítulos V y VI), por considerar que es una discusión actual en el panorama del pensamiento filosófico, y en la cual se ven inmersos estos dos pensadores, en particular en el uso que hacen del vocablo antiautoritarismo (Richard Rorty) y nuevo fascismo social (Boaventura de Sousa). Por último en su Capítulo VII llegaremos a las conclusiones a la que nos ha llevado a nuestra investigación. Al plantear una cuestión como la auctoritas y la postestas en relación con el poder legítimamente constituido dentro del campo de la filosofía política, estamos demostrando un compromiso con la concepción que se tiene de la filosofía, pues en este sentido se entiende como un ejercicio formativo para la construcción del ser humano y no como una disciplina meramente teórica. Por tanto realizaremos una investigación basada en el procedimiento reflexivo, sistemático y crítico de las obras filosóficas, antropológicas, sociológicas…etc., tanto de Boaventura de Sousa como de Richard Rorty. Ya que deberemos tener en cuenta que cada periodo histórico de la filosofía ha tenido una tensión entre pensadores que defendían una estamos aportando un compromiso con la concepción que se tiene de la filosofía, pues en este sentido se entiende como un ejercicio formativo para la construcción del ser humano y no como una disciplina meramente teórica.

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)

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)

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)

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.

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.

Colombian literature of the nineteenth century captures the emerging process of the new nation and shows the ethical changes needed for the formation of a new country. By using the Colombian novel and poetry produced in the nineteenth-century, this paper will show how these are unfolded in practical effects of the works, drawing on the authors’ desire to influence with their work the ethical and political progress of the country, their society and the life of citizens, and to contribute to (...) the foundation of the modern state in Colombia through a citizen ethics proposed in the texts. Additionally, this paper stresses the literary effort of reappraising the national moral and political situation, of confronting this with the past and, accordingly, of assessing the current situation. -/- La literatura colombiana del siglo XIX captura el proceso de la emergente nación e indica los cambios éticos necesarios para la conformación de un nuevo país. Recurriendo a la novela y la poesía colombiana del siglo XIX, se evidenciará cómo se despliega en estas efectos prácticos de las obras, bajo el anhelo del autor de incidir con sus letras en el progreso ético y político del país, la sociedad y la vida de los ciudadanos, con la fundación del Estado Moderno en Colombia a través de una ética ciudadana propuesta en los textos. Igualmente, se resalta el empeño literario de revaluar la situación moral y política nacional, confrontarla respecto al pasado y evaluar la actualidad conforme a ella. (shrink)

Es innegable que desde la publicación de A Theory of Justice en 1971 la filosofía política ha dado un giro en las temáticas que históricamente ha abordado. Pues como afirma Robert Nozick, es imposible realizar cualquier tipo de filosofía práctica, sin considerar el marco teórico ofrecido por la obra de Rawls, dado que lo inédito de su trabajo es ofrecer una teoría sustantiva de justicia que deja atrás la tradición lógica-analítica, así como el mero análisis histórico-sistemático. Las múltiples repercusiones han (...) dado inicio a una vasta cantidad de encuentros y desencuentros en la forma concebir la justicia social. En este debate se enmarca el último libro del profesor Pablo Aguayo Westwood: Justicia social: conceptos, teorías y problemas, donde propone una breve revisión de los principales hitos que han marcado la discusión en torno a la justicia social, así como algunos problemas prácticos que conciernen a esta.
