This thesis sets out an argument in defence of moral objectivism. It takes Mackie as the critic of objectivism and it ends by proposing that the best defence of objectivism may be found in what I shall call Kantian intuitionism, which brings together elements of the intuitionism of Ross and a Kantian epistemology. The argument is fundamentally transcendental in form and it proceeds by first setting out what we intuitively believe, rejecting the sceptical attacks on those beliefs, and by (...) then proposing a theory that can legitimize what we already do believe. Chapter One sets out our intuitive understanding of morality: that morality is cognitive, moral beliefs can be true or false; that morality is real, we do not construct it; that morality is rational, we can learn about it by rational investigation; and that morality places us under an absolute constraint. The chapter ends by clarifying the nature of that absolute demand and by arguing that the critical idea within morality is the idea of duty. In Chapter Two Mackie’s sceptical attack on objectivism is examined. Four key arguments are identified: that moral beliefs are relative to bfferent agents; that morality is based upon on non-rational causes; that the idea of moral properties or entities is too queer to be sustainable; and that moral objectivism involves queer epistemological commitments. Essentially all of these arguments are shown to be ambiguous; however it is proposed that Mackie has an underlying epistemological and metaphysical theory, scientific empiricism, which is hostile to objectivism and a theory that many find attractive for reasons that are independent of morality. Chapter Three explores the nature of moral rationality and whether scientific empiricism can use the idea of reflective equilibrium to offer a reasonable account of moral rationality. It concludes that, while reflective equilibrium is a useful account of moral rationality, it cannot be effectively reconciled with scientific empiricism. In order to function effectively as a rational process, reflective equilibrium must be rationally constrained by our moral judgements and our moral principles. Chapter Four begins the process of exploring some alternative epistemologies and argues that the only account that remains true to objectivism and the needs of reflective equilibrium is the account of intuitionism proposed by Ross. However this account can be developed further by drawing upon number of Kantian ideas and using them to supplement Ross’s intuitionism. So Chapter Five draws upon a number of Kant's ideas, most notably some key notions from the Critique of Judgement. These ideas are: that we possess a rational will that is subject to the Moral law and determined by practical reason; that we possess a faculty of judgement which enables us to become aware of moral properties and that these two faculties together with the third faculty of thought can function to constitute the moral understanding. Using these ideas the thesis explores whether they can serve to explain how intuitions can be rational and how objectivism can be justified. (shrink)

While many have argued that moral disagreement poses a challenge to moral knowledge, the precise nature of this challenge is controversial. Indeed, in the moral epistemology literature, there are many different versions of ‘the’ argument from moral disagreement to moral scepticism. This paper contributes to this vast literature on moral disagreement by arguing for two theses: 1. All (or nearly all) moral disagreement arguments share an underlying structure; and, 2. All moral (...) disagreement arguments that satisfy this underlying structure cannot establish moral scepticism because this underlying structure leads to a previously unrecognized reductio ad absurdum. In short, I argue that this reductio argument (very likely) refutes all versions of the moral disagreement to moral scepticism argument in one fell swoop. (shrink)

Elizabeth Anscombe is well-known for her insistence that there are absolutely prohibited actions, though she is somewhat obscure about why this is so. Nonetheless, I contend in this paper that Anscombe is more concerned with the epistemology of absolute prohibitions, and that her thought on connatural moral knowledge – which resembles moral intuition – is key to understanding her thought on moral prohibitions. I shall identify key features of Anscombe’s moral epistemology before turning to investigate its (...) sources, examining the roots of connaturality in Aquinas and comparing it with rationalist ethical intuitionism, which Anscombe differs from in rejecting “good” as a simple, non-natural property. I then develop a two-stage argument about absolute prohibition: The first will be loosely Thomistic, while the second will suggest how Anscombe’s absolute prohibitions can be seen as a continuation of Wittgenstein’s anti-scepticism in On Certainty. I develop an account of absolute prohibitions as a form of Wittgensteinian hinge proposition – they are not the conclusions of deductive arguments, but the foundations for intelligibility in action.

Proponents of the epistemic companions in guilt argument argue that we should reject the moral error theory because it entails that there are no epistemic reasons. In this paper, I investigate whether a plausible version of the moral error theory can be constructed that does not entail an error theory about epistemic reasons. I argue that there are no irreducibly normative second-personal reasons even if there are irreducibly normative reasons. And epistemic reasons are not second-personal reasons. In this (...) case, a plausible version of the moral error theory can be constructed that does not entail an error theory about epistemic reasons if facts and claims about morality entail facts and claims about irreducibly normative second-personal reasons. And, as I explain, there is a good case that facts and claims about morality do entail facts and claims about irreducibly normative second-personal reasons. (shrink)

Scepticism about ought simpliciter is the view that there is no such thing as what one ought simpliciter to do. Instead, practical deliberation is governed by a plurality of normative standpoints, each authoritative from their own perspective but none authoritative simpliciter. This paper aims to resist such scepticism. After setting out the challenge in general terms, I argue that scepticism can be resisted by rejecting a key assumption in the sceptic’s argument. This is the assumption that standpoint-relative (...) ought judgments bring with them a commitment to act in accordance with those judgments. Instead, I propose an alternative account of our normative concepts according to which only ought simpliciter judgments commit one to acting in accordance with those judgments. In addition to answering the sceptical challenge, the proposal offers an independently motivated account of what makes a concept normatively authoritative. (shrink)

Some moral theorists argue that being an innocent beneficiary of significant harms inflicted by others may be sufficient to ground special duties to address the hardships suffered by the victims, at least when it is impossible to extract compensation from those who perpetrated the harm. This idea has been applied to climate change in the form of the beneficiary-pays principle. Other philosophers, however, are quite sceptical about beneficiary pays. Our aim in this article is to examine their critiques. We (...) conclude that, while they have made important points, the principle remains worthy of further development and exploration. Our purpose in engaging with these critiques is constructive — we aim to formulate beneficiary pays in ways that would give it a plausible role in allocating the cost of addressing human-induced climate change, while acknowledging that some understandings of the principle would make it unsuitable for this purpose.

“Responsibility After ‘Morality’: Strawson’s Naturalism and Williams’ Genealogy” -/- Although P.F. Strawson and Bernard Williams have both made highly significant and influential contributions on the subject of moral responsibility they never directly engaged with the views of each other. On one natural reading their views are directly opposed. Strawson seeks to discredit scepticism about moral responsibility by means of naturalistic observations and arguments. Williams, by contrast, employs genealogical methods to support sceptical conclusions about moral responsibility (and (...) blame). This way of reading their views depends, however, on the assumption that the concept of responsibility that Strawson aims to defend is the same as Williams aims to discredit. The conception of responsibility that Williams aims to discredit is one that is based around the assumptions and aspirations of “the morality system”. This paper argues that while there is a plausible way of interpreting Strawson’s naturalism that uncouples it from the assumptions of “the morality system”, there remain significant differences between Strawson and Williams. More specifically, even if Strawson’s understanding of moral responsibility abandons the (narrow) assumptions of “morality”, Strawson is still committed to “conservative” and “optimistic” conclusions about moral responsibility that cannot be sustained.

Arguments attempting to debunk moral beliefs, by showing they are unjustified, have tended to be global, targeting all moral beliefs or a large set of them. Popular debunking arguments point to various factors purportedly influencing moral beliefs, from evolutionary pressures, to automatic and emotionally-driven processes, to framing effects. We show that these sweeping arguments face a debunker’s dilemma: either the relevant factor is not a main basis for belief or it does not render the relevant beliefs unjustified. (...) Empirical debunking arguments in ethics can avoid this predicament, but only if they are refocused on highly selective classes of moral belief. Experimental data can combine with familiar consistency reasoning to reveal that like cases are not being treated alike. Selective debunking arguments are unlikely to yield sweeping sceptical conclusions, but they can lead to rational moral change. (shrink)

In her influential and challenging paper “Skepticism about Practical Reason” Christine Korsgaard sets out to refute an important strand of Humean scepticism as it concerns a Kantian understanding of practical reason.1 Korsgaard distinguishes two components of scepticism about practical reason. The first, which she refers to as content scepticism, argues that reason cannot of itself provide any “substantive guidance to choice and action” (SPR, 311). In its classical formulation, as stated by Hume, it is argued that reason (...) cannot determine our ends. Our ends are determined by our desires and reason is limited to the role of identifying the relevant means to these ends. The second component, which Korsgaard calls motivational scepticism, suggests doubt about the scope of reason as a motive. The claim here, as Korsgaard interprets Hume’s view on this matter, is that “all reasoning that has motivational influence must start from a passion, that being the only possible source of motivation” (SPR, 314).2 Korsgaard’s fundamental objective in “Skepticism about Practical Reason” is to show that motivational scepticism must always be based on content scepticism. In other words, according to Korsgaard, motivational scepticism has no independent force. In this paper I argue that Korsgaard’s attempt to discredit motivational scepticism is unsuccessful.

This paper defends moral realism against Sharon Street’s “Darwinian Dilemma for Realist Theories of Value” (this journal, 2006). I argue by separation of cases: From the assumption that a certain normative claim is true, I argue that the first horn of the dilemma is tenable for realists. Then, from the assumption that the same normative claim is false, I argue that the second horn is tenable. Either way, then, the Darwinian dilemma does not add anything to realists’ epistemic worries.

Far from being indiscriminately critical of the ideas he associated with the morality system, Bernard Williams offered vindicatory explanations of its crucial building blocks, such as the moral/non-moral distinction, the idea of obligation, the voluntary/involuntary distinction, and the practice of blame. The rationale for these concessive moves, I argue, is that understanding what these ideas do for us when they are not in the service of the system is just as important to leading us out of the system (...) as the critique of that system. I then show how regarding the aspiration to shelter life from luck as the system’s organizing ambition explains why the system elaborates and combines these building blocks in the way it does. Finally, I argue that the ultimate problem with the resulting construction is its frictionless purity. It robs valuable concepts of their grip on the world we live in, and, by insisting on purity from contingency, threatens to issue in nihilism about value and scepticism about agency. (shrink)

A familiar claim, meant as a challenge to moral knowledge, is that we can credibly accept putative moral facts just in case they explain natural facts. This paper critically addresses Elizabeth Tropman’s response to a version of that claim. Her response has interest partly because it falls within, and extends, an influential philosophical tradition – that of trying to expose (some) skeptical challenges as spurious or ill-conceived. Also, Tropman’s target is not just any version of the claim just (...) mentioned. It is Gilbert Harman’s classic version, according to which putative moral facts must earn credibility by explaining the formation of moral beliefs. This version has wide influence, and variations of it can arise in many areas. Tropman’s response is thus well worth attention. (shrink)

Does evolutionary theory have the potential to undermine morality? In his book The Evolution of Morality, Richard Joyce (2006) argues for a positive answer. He contends that an evolutionary account of morality would undermine moral judgements and lend support to moral scepticism. I offer a critique of Joyce’s argument. As it turns out, his case can be read in two different ways. It could be construed as an argument to establish a general scepticism about the justification (...) of moral judgements. Or it could be read as an argument that targets only a particular meta-ethical position, namely moral realism. My claim is that it fails on both interpretations. There is no reason to believe that evolutionary considerations undermine morality. (shrink)

This and the following lessons cover the topic of Vedānta and ethics. Vedānta has two meanings. The first is the literal sense – “End of Vedas” – and refers to the Āraṇyakas and Upaniṣads—the latter part of the Vedas. The second sense of “Vedanta” is a scholastic one, and refers to a philosophical orientation that attempts to explain the cryptic Vedānta Sūtra (Brahma Sūtra) of Bādarāyaṇa, which aims at being a summary of the End of the Vedas. We shall pursue (...) the question of ethics in both senses of Vedānta. In this module we shall examine the ethical theory of Deontology found in the Upaniṣads. Having explored the implications of this model for moral philosophy, we can reflect upon the three commentarial approaches. In this lesson, we will examine Śaṅkara’s Advaita approach. Advaita Vedānta, especially in Śaṅkara's form, presents a version of moral scepticism, or more strongly, moral irrealism. In this account, there is nothing objective about ethics: it mediates our desires-oriented psychology, and should be dispensed with along with the desire-oriented psychology. Śaṅkara seems to come close to doing the impossible: saying insightful things about what he takes to be a fiction, which is the individual self, for which ethics is essential. (shrink)

Over the past few centuries the free will debate has largely turned on the question of whether or not the truth of the thesis of determinism is compatible with the relevant form of freedom that is required for moral responsibility. This way of approaching the free will problem was fundamentally challenged by P.F. Strawson in his hugely influential paper “Freedom and Resentment,” which was published in 1962. In this paper Strawson pursues a line of argument that can be found (...) in the work of several major figures in the “moral sense school,” such as David Hume and Adam Smith. The strategy Strawson employs is one that begins with a complex and subtle description of the attitudes and practices that are constitutive of moral responsibility as we observe it in human life. According to Strawson, both sides in this debate fail to identify the real foundations of moral responsibility, which rests with the fabric of our human emotional psychology. When we start from inside these natural, human commitments, Strawson maintains, we are better placed to generate a viable and pertinent theory of human freedom as it relates to the requirements of moral responsibility.

This paper explores the prospects of different forms of moral error theory. It is argued that only a suitably local error theory would make good sense of the fact that it is possible to give and receive genuinely good moral advice.

The historian Herodotus gives the anecdote of Darius, King of Persia, who summoned the Greeks and asked them if they would be willing to eat the bodies of their dead fathers. They replied they would not for any money in the world. Later, Darius asked some Indians of the tribe called Callatiae, who do eat their dead parents’ bodies, if they would ever consider burning the bodies, as was the custom among Greeks. “One can see by this what custom can do” writes Herodotus. He draws the conclusion that this story vindicates the view some acts may be right for some and wrong for others, depending on their individual conceptions of morality. The Sophists were also associated with relativistic thinking, notably Protagoras who asserts that “man is the measure of all things”. However, this view was quite uncommon and moral relativism hardly flourished, as Plato and Aristotle both defended forms of moral absolutism. Ancient Greek philosophers acknowledged moral diversity, but more often under the form of moral scepticism, which states that there is no moral knowledge (rather than moral truth is relative to a culture).

We are subject to many different norms telling us how to act, from moral norms to etiquette rules and the law. While some norms may simply be ignored, we live under the impression that others matter for what we ought to do. How can we make sense of this normative authority some norms have? Does it fit into our naturalist worldview? Many philosophers claim it does not. Normativity is conceived to be distinct from ordinary natural properties, making it mysterious. (...) The mystery fuels a radical yet prominent scepticism about the existence of normative properties: if they are too strange to actually exist, there is nothing we ought to do. Some take this to mean, moreover, that nothing is morally right or wrong. We must critically examine the ideas behind these theories, which put both morality and normativity in general on the line. -/- The aim of this thesis is to unravel the mystery of normativity. It uncovers and objects to the influential non-natural conception of it, arguing that we can capture normativity with natural properties. In particular, it explores how the authority of norms can be explained by the commitments of the people subject to them. In connection to this, it challenges the conceptual claim behind the view that all moral judgements are mistaken. Finally, it reveals that treating morality as a mere fiction has revolutionary practical implications. This emphasises the importance of the overall conclusion: we need not conceive of either moral or normative properties as too mysterious to exist. (shrink)

A number of recent writers have expressed scepticism about the viability of a specifically moral concept of obligation, and some of the considerations offered have been interesting and persuasive. This is a scepticism that has its roots in Nietzsche, even if he is mentioned only rather rarely in the debate. More proximately, the scepticism in question receives seminal expression in Elizabeth Anscombe's 1958 essay, ‘Modern Moral Philosophy’, a piece that is often paid lip-service to, but—like (...) Nietzsche's work—has only rarely been taken seriously by those wishing to defend the conception of obligation under attack. This is regrettable. Anscombe's essay is powerful and direct, and it makes a forthright case for the claim that, in the absence of a divine law conception of ethics, any specifically moral concept of obligation must be redundant, and that the best that can be hoped for in a secular age is some sort of neo-Aristotelianism. Anscombe is right about this, we think. And, among those who disagree, one of the very few to have taken her on at all explicitly is Christine Korsgaard, whose Kantianism of course commits her to the view that the concept of moral obligation is central, with or without God. Here, we try to show that Korsgaard loses the argument. (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)

This chapter outlines a new disentangling strategy for moral epistemology. It builds on the fundamental distinction between value-neutrality and value-independence as two separate aspects of methodological austerity introduced by Matthew Kramer. This type of conceptual analysis is then applied to two major challenges in moral epistemology: globalised scepticism and debate fragmentation. Both challenges arise from collapsing the fact/value dichotomy. They can be addressed by comprehensive disentangling that runs along both dimensions – value neutrality vs. value non-neutrality and (...) value independence vs. value dependence. The success of this strategy rests on two factors. The first is broadening the scope of disentangling to include theoretical-explanatory values on a par with distinctly ethical values. The second is differentiating between wider and narrower conceptualisations of what value neutrality requires with respect to contested matters. The objective is to pre-empt unjust theorising, a distinctive form of epistemic injustice that derives from the exclusive methodological focus on ethical evaluations at the expense of epistemic ones. When these methodological conditions are fulfilled, opponents should gain the confidence to treat each other as fellow inquirers engaged in the same project, that of reducing the scope of unhelpful disagreements.

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)

John Rawls shows a deep influence of David Hume’s thought, mainly at his Theory of Justice, though also at the rest of his works. This influence is well-known in the field of political philosophy, much less in the field of moral philosophy. Rawls reads Hume’s thought with a sceptic and naturalistic key, attributing him what he calls a “nature fideism”. Besides this, attributes to Hume an ethical and political position linked with the classical utilitarianism. Nevertheless, his skeptical epistemology will (...) move away, paradoxically, to Hume from the utilitarian positions. Hume’s ethics and politics will finish, according to Rawls, showing a purely descriptive character and a lack of normative purposes. Hume does not have in the strict sense a theory of practical reason. This article examines and puts in question this interpretation of Hume proposed by John Rawls. The philosophy of Hume is not aporetically skeptical, articulates the moral roles of reason and the passions; and finally, is not only connected with utilitarianism; his defense of the role of utility frees to his theory of some of the main contradictions of classical utilitarianism. Besides this, the theory of the “judicious spectator” can be considered a form of a theory of practical rationality. (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.

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)

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.

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)

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.
