Philosophy of Mind

Studying the meta-problem of consciousness has many advantages in getting to understand the hard problem. However, the science on the meta-problem is arguably very pre-mature. A lot of philosophical work on clarifying the problem needs to be done before we can come up with promising theories to solve it. Especially what exactly the central explanandum of the meta-problem is, is yet unclear. I argue that every meta-problem theory needs to account for (I) the uniqueness of the meta-problem, (II) needs to (...) be in line with empirical data, and (III) must be susceptible for topic-neutral explanations. By using a problem-intuitions oriented approach, investigation on (I) reveals that the only explanation for the uniqueness (and the very existence) of the meta-problem is acquaintance, since our immediate epistemic access to our conscious experiences is just what makes our problem intuitions about consciousness what they are, i.e. uniquely puzzling. However, if acquaintance is the main explanandum of the meta-problem, we must expect acquaintance to be the source of all problem intuitions. This then, must be manifested in a very high degree of universality of knowledge intuitions (to which acquaintance intuitions belong). Luckily, this is exactly what we seem find when consulting current empirical data and what can strongly be expected to be revealed by future studies from X-Phi. The problem of topic-neutrality poses no objection to acquaintance being the main explanandum, since it just formulates the underlying problem of the meta-problem: Explain acquaintance in topic-neutral terms or explain why this can’t be done.

This article evaluates the political implications of Thomas Hobbes’s extensive treatment of religion by taking up the motif of the Eucharist (and accompanying doctrine of transubstantiation) in Leviathan. Hobbes holds out transubstantiation as an exemplar of absurdity and an historical outgrowth of Christianity’s inauspicious meeting with pagan practices. At the same time, Leviathan contains allusions to eucharistic imagery in its narration of the generation of the “Mortal God,” the commonwealth, as the incorporation of a civil body. These conflicting sentiments are (...) illustrative of a wider tension running through Hobbes’s thought. Although Hobbes’s repudiation of superstition is well-known, it stands in stark contrast to Leviathan’s treatment of Christianity as an exemplar of “true” religion. The varied allusions to eucharistic doctrine illustrate how proper use might be made of a persistent “natural religiosity.” Both in its consonance with reason and its political logic, Christianity remains a politically constructive expression of “power invisible.”.

By religious experiences I mean those human experiences characterised by a kind of intuitional seeming to the effect that a transcendent or all‐encompassing being—God—exists. After explaining two significant similarities between religious and perceptual experiences, I will argue that the doctrine of phenomenal dogmatism about perceptual experiences can be applied to religious experiences as well. In the following two sections, the challenge arising from the objection from cognitive penetration is extended to the case of religious experiences. I show that the importance (...) of this challenge may be dependent on a debate over the proper content of experience—namely the debate over low‐level vs. high‐level content. In the subsequent section, I argue that even if the religious experience is deemed an experience with low‐level content, then the charge of cognitive penetration may not be avoided. Drawing upon the doctrine of divine simplicity, in the penultimate section, I argue that the experience of God has a specific characteristic which, in companion with its thin content, enables it to escape the charge of cognitive penetration. Alternatively put, the experience of God possesses an important epistemological advantage owing to its distinctive object, which makes it significantly reliable. In the final section, three possible objections are briefly addressed. (shrink)

Theories of intense national emotions have focused on affection for the home nation and antagonism for national others but overlooked antagonism for fellow nationals. The article introduces a comprehensive theory of intense national emotions. It first discusses the sources of the potential energy stored in national identities, pointing to a combination of two factors: the nation is at once potent due to its capacity to shield against existential threats and precarious due to its dependence on the reproduction of contested narratives. (...) The article then explains that events that—through a construction process elaborated in the text—seem to threaten or promise to alter perceived core elements of the nation (i.e., “nation-disrupting events”) evoke intense emotions. Next, the article explains why some periods of "hot" nationalism increase national division rather than unity. The conclusion proposes a promising direction for future research on intense national emotions as a mechanism of eventfulness. (shrink)

Filozofia pamięci jest gorącym tematem w kognitywistyce i filozofii umysłu. Niniejsza praca analizuje spór między symulacjami a przyczynową teorią pamięci poprzez badanie poczucia swojskości i jego związku ze śladami pamięciowymi, a dokładniej w jaki sposób zwiększają one płynność rekonstrukcji przeszłych epizodów. Zrozumienie relacji między śladami swojskości i pamięci, a ponadto relacji między pełnoprawną fenomenologią pamięci a poczuciem subiektywnej pewności epizodu, jaki miał miejsce w przeszłości, prowadzi do odmiennej interpretacji rywalizacji między tym, co przyczynowe, a tym, co symulacyjne.

Psychological and philosophical studies have extended J. J. Gibson’s notion of affordances. Affordances are possibilities for bodily action presented to us by the objects of our perception. Recent work has argued that we should extend the actions afforded by perception to mental action. I argue that we can extend the notion of affordance itself. What I call ‘Introspective Affordances’ are possibilities for mental action presented to us by introspectively accessible states. While there are some prima facie worries concerning the non-perceptual (...) nature of introspection, I will argue that our internal mental lives share enough commonalities with experiences in our environment to warrant this extension. I will demonstrate the value of introspective affordances by showing how they allow us to explain an underexplored aspect of thought insertion. (shrink)

Some theories of consciousness emphasize its relationship to language, its emergent quality, and its causal role. Prominent among these theories is the one that Dennett has been developing for nearly four decades. According to Dennett’s most recent version, consciousness is a kind of cerebral clout. But consideration of examples of pain—arguably the best candidate on offer for a paradigm of consciousness—reveals that clout is neither necessary nor sufficient for consciousness. Moreover, pain doesn’t necessarily have the aftermath that is predicted by (...) Dennett’s Clout Theory (CT); pain cannot always be accommodated by Dennett’s methodology; and, pain does not always conform to Dennett’s proposed ontology. Dennett might wish to substitute episodic memory as a preferred paradigm for consciousness, but episodic memory is shown to be non-essential. And, were it to be treated as a paradigm of consciousness, it would create new explanatory problems for CT. Rather than abandoning CT, because it does seem to help explain some pain phenomena and because it does comport well with certain views of language, I propose that some of its more intriguing proposals be retained and treated as hypotheses to guide further empirical inquiry. Finally, I recommend some specific empirical cases wherein relevant research might be pursued. (shrink)

This paper explores the hypothesis that proper names serve as anchors identifying the individuals in the possible or real world. This hypothesis is tested on Old Icelandic narratives. A prominent feature of Old Icelandic sagas is that the narrative matter is not quite new. A Saga is reliable iff it refers to the events relevant for its audience and accepted as true by the whole community. I argue that proper names must be regarded as references to the background knowledge of (...) the medieval audience. I follow two contemporary Sagas based on the fresh events and show that proper names in a Saga mind were arranged in form of a database, each type of a personal designation having its charachteristic text-building profile. The form of the name and its frequency in the Saga are linked with the rank of the character. The high number of people mentioned in the Sagas is explained by the fact that the Sagas aimed at describing the real world, where the names of the individuals and the events they were involved cross-identified each other. Every character had its rigid identifiers. The total amount of propria is always higher than the number of active figures. I classify the Saga characters into five ranks and discuss their information-structural profiles. (shrink)

Toward a theory of n-tuples of individuals and concepts as surrogates for Russellian singular propositions and singular concepts. Alonzo Church proposed a powerful and elegant theory of sequences of functions and their arguments as singular-concept surrogates. Church’s account accords with his Alternative (0), the strictest of his three competing criteria for strict synonymy. The currently popular objection to strict criteria like (0) on the basis of the Russell-Myhill paradox is here rebutted. As Church recognized, Russell-Myhill is not a problem specifically (...) for Alternative (0). Rather it is a disproof of unrestricted concept comprehension. Unrestricted comprehension is also inconsistent with the facts about sets of properties. It is demonstrated furthermore that the principal rival conception of propositions--propositions conceived as classes of possible worlds--is subject to a fatal philosophical collapse: It follows on that conception, given that each of us is fallible, that everyone believes everything. Although it is far superior to its principal rival conception, Church’s proposed theory is vulnerable under (0) to a version of Russell’s notorious Gray’s /Elegy/ objection. Some amendments to Church’s proposal are proffered that address Russell’s objection, including an amendment first proposed in the present author’s /Frege’s Puzzle/ (1986). Church’s response (personal correspondence) is considered. (shrink)

The subject of this paper is the relationship between religion and sport. The aim of my considerations is to criticise the position presented by the American philosopher Eric Bain-Selbo, according to which sporting experiences may quite rightly be described as religious experiences. In the first part of the article, I reconstruct Wayne Proudfoot’s concept of religious experience that underlies Bain-Selbo’s analysis. I then discuss the research conducted by Bain-Selbo and the conclusions he draws from it. In the next part of (...) the article, referring to Charles Taylor’s hermeneutical approach, I show that Proudfoot’s and Bain-Selbo’s methodology leads to a theoretically unjustified reductionism. I argue that an in-depth articulation of individual self-interpretation allows for an insight into the dynamics of sporting and religious experiences, and thus to see the differences that separate them. In the last part of the article, I invoke the considerations of William James, John Hick and Robert Roberts and try to show that, given the moral consequences of our experiences and their phenomenological description (intentionality), the experiences evoked by sport and religion can by no means be identified with each other.

Patient suffering of major depressive disorder (MDD) often complain that subjective time seems to “drag” with respect to physical time. This may point toward a generalized dysfunction of temporal processing in MDD. In the present study, we investigated temporal preparation in MDD. “Temporal preparation” refers to an increased readiness to act before an expected event; consequently, reaction time should be reduced. MDD patients and age-matched controls were required to make a saccadic eye movement between a central and an eccentric visual (...) target after a variable duration preparatory period. We found that MDD patients produced a larger number of premature saccades, saccades initiated prior to the appearance of the expected stimulus. These saccades were not temporally controlled; instead, they seemed to reflect reduced inhibitory control causing oculomotor impulsivity. In contrast, the latency of visually guided saccades was strongly influenced by temporal preparation in controls; significantly less so, in MDD patients. This observed reduced temporal preparation in MDD was associated with a faster decay of short-term temporal memory. Moreover, in patients producing a lot of premature responses, temporal preparation to early imperative stimuli was increased. In conclusion, reduced temporal preparation and short-term temporal memory in the oculomotor domain supports the hypothesis that temporal processing was altered in MDD patients. Moreover, oculomotor impulsivity interacted with temporal preparation. These observed deficits could reflect other underlying aspects of abnormal time experience in MDD. (shrink)

Neural activity varies continually from moment to moment. Such temporal variability (TV) has been highlighted as a functionally specific brain property playing a fundamental role in cognition. We sought to investigate the mechanisms involved in TV changes between two basic behavioral states, namely having the eyes open (EO) or eyes closed (EC) in vivo in humans. To these ends we acquired BOLD fMRI, ASL, and [18F]-fluoro-deoxyglucose PET in a group of healthy participants (n = 15), along with BOLD fMRI and (...) [18F]-flumazenil PET in a separate group (n = 19). Focusing on an EO- vs EC-sensitive region in the occipital cortex (identified in an independent sample), we show that TV is constrained in the EO condition compared to EC. This reduction is correlated with an increase in energy consumption and with regional GABAA receptor density. This suggests that the modulation of TV by behavioral state involves an increase in overall neural activity that is related to an increased effect from GABAergic inhibition in addition to any excitatory changes. These findings contribute to our understanding of the mechanisms underlying activity variability in the human brain and its control. (shrink)

In this paper, I share my story about some of my experiences with doubt. Along the way, I also share some philosophical reflections. I know this does not tell you very much, but like I said, I am telling a story, and I do not want to spoil the ending.

This paper explores the relationship between technological and human intelligence through ‘The New Natural’, a term which at once accepts the nature of technological intelligence as real instead of forever ‘artificial’. It supports an evolutionary, reciprocal relationship between humans and technology that culminates in technological singularity and rejects the primacy of human perception known to popular human access theories, before seriously considering the ‘decentered’ implications of posthuman access. In conversation with western-centric sci-fi film of the late twentieth century, then, this (...) philosophical study explores how the concept of a technology-only intelligence entity can: (1) help us dispose of the core problems often associated with human-only access, (2) neutral-ize our fears of human annihilation at the hands of technological intelligence, and (3) establish strong grounds for why we may have to push back against early conceptions of nature’s opposition to technology, if only so we may resist falling into the great, and most human-centered traps known to the Anthropocene.

Emotions play vital roles in our psychology and our lives. They also often form the basis of our evaluative beliefs. On some views, emotions, like perceptions, justify the beliefs to which they give rise. It has, however, been claimed that, unlike perceptions, emotions are merely proxies for the genuine reasons that are constituted by their cognitive bases. In this paper, I argue that this objection arises from the failure to notice the difference between the notions of ‘reasons there are’ and (...) ‘possessed reasons’. After developing an account of what it is to possess a reason, it will be argued that emotions do constitute genuine reasons for the evaluative beliefs that result from them. To support this claim, a distinction is made between thinner and thicker descriptions of the same event, where a thinner description may be in terms of the emotional response, whereas a thicker description may be in terms of possessing a normative reason to hold a belief or to act.

In the contemporary literature on panpsychism, one often finds the claim that a Russellian-monist version of panpsychism, i.e., _Russellian panpsychism_, is a superior view compared to alternative non-physicalist theories. The argument for this claim is that while Russellian panpsychism can integrate consciousness in the causal order and explain mental causation, alternative theories fail to do so. If this is correct, panpsychism deserves its place as a main contender in solving the mind-body problem. In this paper, I argue that Russellian panpsychism’s (...) superiority in explaining mental causation over competing accounts is illusory. On one reading, the proposed explanation is not an explanation of the phenomenon that is at stake in the mental causation debate. On an alternative reading, it is an explanation of the right phenomenon, but analogous explanations are available to competing accounts with less counterintuitive commitments. While there may be other considerations supporting panpsychism, explaining mental causation is not one. (shrink)

Many philosophers today accept that phenomenal truths cannot be explained in terms of ordinary physical truths. Two possible routes to accounting for consciousness have received much attention: the emergentist route is to accept that ordinary experience is inexplicable in physical terms but that microscopic entities as described in physics nonetheless bring about conscious experience. The second route is to argue that microscopic entities have features not described in physics which can fully explain conscious experience. The view associated with panprotopsychism is (...) that microscopic entities have no phenomenal properties. The view associated with panpsychism is that microscopic entities do have phenomenal properties. In this paper it is argued that if consciousness is extended in space only the latter view is possible. According to this argument for micropsychism, if phenomenal truths are not merely structural, all truths about a whole are truths about its parts plus structural relational truths. If there are phenomenal truths about the whole, this must be because there are phenomenal truths about its parts. It wouldn’t follow that panpsychism is true, since it does not follow that consciousness exists outside the wholes we know to be conscious, but it does follow that emergentism and protopanpsychism are false.

Some philosophers claim that perception immediately and prima facie justifies belief in virtue of its phenomenal character (Huemer, Skepticism and the veil of perception. Rowman & Littlefield, Lanham, 2001; Pryor, There is immediate justification. In: Steup M, Sosa E (eds) Contemporary debates in epistemology. Blackwell, London (2014), pp. 181–202, 2005). To explain this special justificatory power, some appeal to perception’s presentational character: the idea that perceptual experience presents its objects as existing here-and-now (Chudnoff, Intuition. Oxford University Press, Oxford, 2013; Berghofer, (...) Husserl Stud 34(2):145–170, 2018). As some philosophers have noted, if perception justifies in virtue of its presentational character alone, the kind of content perception has should not matter for perceptual justification; more precisely, it should not matter whether perceptual content is propositional or not (e.g., Smithies, The epistemic role of consciousness. Oxford University Press, Oxford, 2019; Kriegel, Australas J Philos, 2021). However, most philosophers tend to resist this conclusion, holding that perception must be propositional in order to justify, on the ground that all our model of justification are propositional (e.g., Gauker, Philos Perspect 26(1):19–50, 2012). This paper challenges this claim. The paper consists of a negative and a positive part. In the negative part, I discuss and reject the master argument for the propositionality of perception; the conclusion is that propositional content is neither sufficient nor necessary to explain perception’s justificatory power. In the positive part, I take this conclusion seriously and outline an objectual model of perceptual justification. I define objectual attitudes as mental states whose content is not a full proposition, but a sub-propositional representational item, such as the representation of objects, properties, and kinds (Grzankowski and Montague, Non-propositional intentionality. Oxford University Press, Oxford, 2018), and show that it is plausible that some perceptions and some beliefs are attitudes of this kind. I then argue that objectual perceptual experiences have the right kind of phenomenal character and the right kind of structure to serve for immediate prima facie justification. I conclude by defending my objectual model from three objections. (shrink)

“1950’li yıllarda dönemin büyük felsefecileri arasında dinsel inancı savunan bir kişi bile yoktu. 1990’lı yıllarda Yale’den UCLA’ya, Oxford’dan Heidelberg’e kadar birçok yerde insanın manevi yanını savunan ve geliştiren yüzlerce kitap yazılacak, sel olup akacaktı.

It is astonishing that we humans are able to have, act on and express moral beliefs. This dissertation aims to provide a better philosophical understanding of why and how this is possible especially when we assume metaethical expressivism. Metaethical expressivism is the combination of expressivism and noncognitivism. Expressivism is the view that the meaning of a sentence is explained by the mental state it is conventionally used to express. Noncognitivism is the view that the mental state expressed by a moral (...) sentence is a noncognitive, desire-like state. The central question of this dissertation is this: "How can metaethical expressivists explain that we are able to express moral beliefs?" The shortest answer this dissertation will give is the following: "by becoming `dispositional expressivists´." Dispositional expressivists hold that moral beliefs are dispositions to be in certain mental states that resemble desires. More precisely, a central thesis of this study is that to hold a moral belief is to be disposed to be in a desire-like, noncognitive state where this state has some specific structure. This dissertation arrives at and justifies this thesis by making a number of steps. It starts with preparing the ground by developing a general theory of what it is for a sentence to express a mental state. Roughly, this theory states that for a sentence to express a mental state is for that sentence to be conventionally used to perform a speech act which counts as sincere only if the user or speaker is in that mental state. This theory of expressing satisfies all the constraints that must be satisfied for it to be compatible with the purposes of metaethical expressivism. The next step is to provide a solution to the most notorious semantic problem confronting metaethical expressivism, the problem of explaining how sentences containing moral words can have compositional meaning and stand in logical relations also known as the Frege-Geach or embedding problem. Building on the research of Mark Schroeder, a new expressivist semantics, called `Attitude Semantics´, will be developed for a first-order language. The motivating idea underlying attitude semantics is that expressivists can avoid the problematic feature of so-called `biforcation´ if they treat the structures of the mental states expressed by moral sentences as well as that expressed by non-moral sentences as being isomorphic. In order to give those structures a philosophically interesting interpretation, it will be suggested that we treat sentences as expressing dispositional states. As a toy example we will treat the sentence `murder is wrong´ as expressing the disposition to be for blaming for murder. After dealing with the Frege-Geach problem, I turn to the metaethical expressivists' project of quasi-realism. Two major goals of this project are to explain how moral sentence can be truth-apt and how the states expressed by them can be regarded as moral beliefs. In order to establish those goals I critically examine a number of theories of truth-aptness by providing counterexamples to them. I then present my own theory which says that a sentence is truth-apt iff and because there is a conventional way to use it to express a belief. What is new about this theory is that it treats expressing a belief as being explanatorily more basic than being truth-apt. Belief, according to this theory, explains truth-aptness, not vice versa. This has the important consequence that it shows that what I call the `orthodox strategy´ of quasi-realists is mistaken and needs to be inverted: expressivists must `earn the right´ to moral belief before they can establish that moral sentences are truth-apt, and not the other way round. The second part of this dissertation is then concerned with the question of what it is to hold a moral belief and how they can figure in rational reasoning. In short: it is concerned with earning the right to moral belief. After discussing the major problems confronting a noncognitivist theory of belief, most importantly what I call the `tightrope problem´, I argue for a dispositional form of noncognitivism about moral belief that combines elements from Eric Schwitzgebel's dispositionalism about belief and Sebastian Köhler's `conceptual role expressivism´. This dispositional noncognitivism perfectly matches and justifies the dispositionalist interpretation of the expressivist semantics developed before. In order to fully earn the right to moral belief, however, metaethical expressivists must also deal with several epistemological objections concerning the rationality of moral belief. The first objection I deal with comes from Derek Baker and is directed against Mark Schroeder's specific development of expressivism. I deal with this objection because my own theory bears close resemblance to Schroeder's theory and so it might be worried that it confronts the same issues. Fortunately, we will see that Baker's objection rest on a number of mistaken assumptions and so neither applies to Schroeder's expressivism nor to the version which I defend in this study. The other epistemological objection to metaethical expressivism I deal with is Cian Dorr's famous wishful-thinking objection. In contrast to previous replies to this objection I attack it by directly questioning the central assumption on which it rests, namely that reasoners can never be justified in basing a factual belief on a desire-like state. I argue that this is false, and that under certain conditions reasoning from desire-like mental states to factual beliefs is justified. My argument shows that even if holding a moral belief is being in a desire-like noncognitive state, basing factual belief on a moral belief can give one an epistemic reason for the factual belief. Hence, even if moral thoughts are wishes, moral thinking is not wishful thinking. I take my arguments to earn the dispositional expressivist the right to moral belief. By the previously defended theory of truth-aptness in terms of belief, this allows the dispositional expressivists to conclude that moral sentences are also truth-apt. This finishes the quasi-realist project of this dissertation. In the last part of this dissertation I switch gears and present two unnoted problems for metaethical expressivists having to do with explaining moral motivation. Both arguments are surprisingly simple. The first one is this: if motivation requires a belief as well as a desire (Humeanism), and moral judgments motivate by themselves (internalism), then moral judgments cannot be desires only. If this argument is sound, it shows that the famous `motivation argument´ not only entails the falsity of cognitivism, but also the falsity of noncognitivism. The second argument is the following: moral judgments when combined with suitable external desires motivate to act (externalism), but if motivation requires belief as well as desire (Humeanism), then moral judgments cannot be desires only. I discuss several ways in which noncognitivists might want to deal with those problems, but leave it as an open question whether those solutions will ultimately be viable. Overall, this dissertation makes serious contributions to the research program of metaethical expressivism. It makes proposals for how to solve a number of notorious problems, such as the Frege-Geach problem in semantics and the wishful-thinking problem in epistemology. Besides this, however, it also raises two new problems for metaethical expressivism in the philosophy of action. For those reasons this dissertation will be of interest for anyone who wants to defend or criticize expressivism in metaethics, and more generally, anyone who wants to better understand our astonishing ability to express moral beliefs.

This paper explores how Charles Peirce’s habit-based epistemology leads him to theorise perception. I show how Peirce’s triadic semiotic analysis of perceptual judgment renders his theory of perception neither a representationalism nor a relationism /direct realism, but an interesting hybrid of the two. His view is also extremely interesting, I argue, in the way that by analysing symbols as habits it refuses the common assumption that perception is an affair best understood synchronically, as a ‘language-entry event’. Relatedly, I extend previous (...) work (Legg 2008) which argues that Peirce’s epistemology counts as a ‘hyperinferentialism’ in Robert Brandom’s terms, but this does not mean that Peirce’s theory of perception cannot accommodate unmediated contact with reality - what Peirce called ‘the outward clash’.

Objective Manic and depressive phases of bipolar disorder (BD) show opposite psychomotor symptoms. Neuronally, these may depend on altered relationships between sensorimotor network (SMN) and subcortical structures. The study aimed to investigate the functional relationships of SMN with substantia nigra (SN) and raphe nuclei (RN) via subcortical-cortical loops, and their alteration in bipolar mania and depression, as characterized by psychomotor excitation and inhibition. -/- Method In this resting-state functional magnetic resonance imaging (fMRI) study on healthy (n = 67) and BD (...) patients (n = 100), (1) functional connectivity (FC) between thalamus and SMN was calculated and correlated with FC from SN or RN to basal ganglia (BG)/thalamus in healthy; (2) using an a-priori-driven approach, thalamus-SMN FC, SN-BG/thalamus FC, and RN-BG/thalamus FC were compared between healthy and BD, focusing on manic (n = 34) and inhibited depressed (n = 21) patients. -/- Results (1) In healthy, the thalamus-SMN FC showed a quadratic correlation with SN-BG/thalamus FC and a linear negative correlation with RN-BG/thalamus FC. Accordingly, the SN-related FC appears to enable the thalamus-SMN coupling, while the RN-related FC affects it favoring anti-correlation. (2) In BD, mania showed an increase in thalamus-SMN FC toward positive values (ie, thalamus-SMN abnormal coupling) paralleled by reduction of RN-BG/thalamus FC. By contrast, inhibited depression showed a decrease in thalamus-SMN FC toward around-zero values (ie, thalamus-SMN disconnection) paralleled by reduction of SN-BG/thalamus FC (and RN-BG/thalamus FC). The results were replicated in independent HC and BD datasets. -/- Conclusions These findings suggest an abnormal relationship of SMN with neurotransmitters-related areas via subcortical-cortical loops in mania and inhibited depression, finally resulting in psychomotor alterations.

The use of evolutionary explanations to explain phenomena at the individual level has been described by various authors as an explanatory error, the so-called Phylogeny Fallacy. In this paper, this fallacy will be analyzed in the context of teleosemantics, a central project of the philosophy of mind whose main aim is to naturalize intentional systems by appealing to their biological teleofunctions. I will argue that those teleosemantics projects that invoke evolutionary functions generally commit the fallacy. First, I will point to (...) various arguments in the literature that point to this fallacy. However, a more general argument will also be made. To illustrate this puzzling scenario, I will present two desiderata that any teleosemantic project must fulfill. I will argue that naturalizing intentionality based on natural selection creates an explanatory gap between types and tokens. This gap prohibits an adequate explanation of the desiderata. To close the gap, teleosemantics invokes replicator biology, a view of inheritance that has already been identified to commit the fallacy. This leads teleosemantics into a complex situation: to close the gap, it must commit the fallacy. (shrink)

In this chapter, we examine the naturalist approach in the philosophy of memory through the lens of the simulation theory of memory. On the theory, episodic memory is a kind of constructive simulation performed by a functionally specialized neurocognitive system. Taking naturalism to be a kind of methodological stance characterized by a cluster of epistemic guidelines, we illustrate the roles these guidelines have played in the development of the theory. We show how scientific evidence has guided both the selection of (...) the research question and the initial elaboration of the theory. We demonstrate how such evidence has led the simulationist to reject a familiar, commonsense picture of memory. We also trace the recent radicalization of the theory, highlighting the simulationist's continual reflection on their concepts and assumptions. In the spirit of such reflection, we end by outlining some outstanding challenges for the theory. (shrink)

In several places of his work, Kant distinguishes between two senses of self-consciousness: a pure one and an empirical one. The aim of this work is to analyze these two senses of consciousness and show that, for Kant, self-consciousness does not occur unrestrictedly: a relation with something other than consciousness is needed for it to become conscious of itself. I carry out these objectives throughout six sections. In the first one I lay out the Kantian principle of pure apperception. In (...) the second one, I present the limits of pure apperception through Kant’s critique of rational psychology. Then, in the third section, I set the basis to understand the relationship that Kant establishes between the I think and the I exist. In the fourth one I show that pure apperception, despite being pure, is not possible without the opportunity of perception. Next, in the fifth one, I introduce the notion of empirical apperception, establish its relationship with pure apperception, and elucidate its meaning. Finally, in the last section, I explain the way in which empirical self-consciousness is determined, in relation to the knowledge of objects of the external sense. (shrink)

The concept of a reason is now central to many areas of contemporary philosophy. Key theses in ethics, epistemology, political philosophy, philosophy of action, and the philosophy of the emotions, among others, have come to be framed in terms of reasons. And yet, despite their centrality, theorists seem to take inconsistent things for granted about how reasons work, what kinds of things can be reasons, what reasons favor, and more. Somehow reasons have come to be both indispensable and impenetrable. -/- (...) The Fundamentals of Reasons offers a comprehensive introduction to the philosophy of reasons. Focusing on the twin roles of reasons in explanation and deliberation, the book not only emphasizes what has made reasons central across philosophy but it also explores why philosophers have such incompatible pictures about what reasons are and how they work. Working from the inside out, Howard and Schroeder identify contentious assumptions about not only the internal structure of reasons but also their relationship to other important concepts, and then show how these contentious assumptions shape the many downstream applications of reasons in ethics, epistemology, political philosophy, and beyond. -/- This mildly opinionated exploration of key questions about the significance and nature of reasons helps the reader to navigate this important part of the philosophical landscape and to get clearer about why reasons seem important and what their import, ultimately, is.

We can best understand the nature of consciousness through metaphor, by putting ourselves imaginatively in the place of the brain. Neural processes evoke sensation and meaning in the way that words evoke mental images. Conscious experience is (like) a virtual reality produced by the brain, guided by interaction with the external world. Explanation occurs in the field of view of the subject, so to speak. To explain the existence of that field inevitably involves circularity.

It is a commonplace that imagination is heterogeneous: we need to draw a series of cross-cutting distinctions even to begin any serious general discussion of the range of activities we take to be typical instances. The nature of the heterogeneity being exhibited is usually left unclear, however, and thus so are its consequences both for our understanding of imagination and for assessing certain challenges such as reductionism. Here it is argued that we can accept heterogeneity while recognizing important forms of (...) unity among the various kinds of imaginative activity. Four distinct but compatible strategies are considered, three of which have historical precedents in Aristotle’s and Hegel’s work. These proposals yield an interesting and plausible answer to the problem raised by heterogeneity, and have consequences for how we should respond to it. They share a plausible framework for thinking about the relationships among the various activities contemporary thinkers take to involve imagination. However, there are some ways in which deploying them is not straightforward, given some differences between modern approaches and older ones, and they conflict with a common thought about the epistemic status of imagination.

This study aims to provide a coherent new interpretation of the notorious anti-hedonism of Speusippus, Plato’s nephew and the second scholarch of the Academy, by reconsidering all the relevant sources concerning his attitude toward pleasure—sources that seem to be in tension or even incompatible with each other. By reassessing Speusippus’ anti-hedonism and Aristotle’s response, it also sheds new light on the Academic debate over pleasure in which he and Aristotle participated: This debate is not merely concerned with the truth and (...) credibility of the arguments for or against hedonism; there are also notable differences among the participants in their understanding of the practical significance of evaluating hedonic experiences. This new interpretation allows us to better understand Aristotle’s selective representation of the intra-school debate and some neglected features of his responses to different interlocutors.

Some philosophers argue that we should be suspicious about shame. For example, Nussbaum endorses the view that shame is a largely irrational or unreasonable emotion rooted in infantile narcissism. This claim has also been used to support the view that we should largely abandon shaming as a social activity. If we are worried about the emotion of shame, so the thought goes, we should also worry about acts which encourage shame. I argue that this line of reasoning does not license (...) the leap from the critique of shame to the critique of shaming. This is because shaming does not always aim to inflict shame on its targets. Many acts of shaming (which I label ‘performative shaming’) should simply be understood as aiming to serve their characteristic function of shoring up social norms and standards. (shrink)

This is a reply to Luke Roelof's comments (2017) on my paper "A Dilemma for Russellian Monists about Consciousness" (2015). On both Russellian monism and dualism, experiences are distinct from neural-functional states and they are correlated with some neural-functional states and not others. The only difference between them concerns the status of the extra-logical principles linking experiences with their neural-functional correlates (e. g. increasing S1 firing rates results in increasing pain): Russellian monists hold that they are a priori and necessary, (...) while dualists say that they are a posteriori and contingent. How are we to decide between them? Roelofs suggests that Russellian monism is simpler than dualism. I argue against this. Both face the "T-shirt problem": both require a swarm of extra-logical principles linking brain states with experiences. The Russellian monist might engage in some unbridled speculation: they are somehow derivable from small set of more basic extra-logical principles ("principles of combination"), even if we cannot supply the details. But the dualist can do the same. The only difference is that the dualist will speculate that those more basic principles are contingent rather than necessary a priori. Given our limited evidence, there is no reason (and in particular no simplicity-based reason) to prefer the Russellian monist's speculations to the dualist's parallel speculations. (shrink)

In this paper I return to Hubert Dreyfus’ old but influential critique of artificial intelligence, redirecting it towards contemporary predictive processing models of the mind (PP). I focus on Dreyfus’ arguments about the “frame problem” for artificial cognitive systems, and his contrasting account of embodied human skills and expertise. The frame problem presents as a prima facie problem for practical work in AI and robotics, but also for computational views of the mind in general, including for PP. Indeed, some of (...) the issues it presents seem more acute for PP, insofar as it seeks to unify all cognition and intelligence, and aims to do so without admitting any cognitive processes or mechanisms outside of the scope of the theory. I contend, however, that there is an unresolved problem for PP concerning whether it can both explain all cognition and intelligent behavior as minimizing prediction error with just the core formal elements of the PP toolbox, and also adequately comprehend (or explain away) some of the apparent cognitive differences between biological and prediction-based artificial intelligence, notably in regard to establishing relevance and flexible context-switching, precisely the features of interest to Dreyfus’ work on embodied indexicality, habits/skills, and abductive inference. I address several influential philosophical versions of PP, including the work of Jakob Hohwy and Andy Clark, as well as more enactive-oriented interpretations of active inference coming from a broadly Fristonian perspective.

When the third global plague pandemic reached Sydney in 1900, theories regarding the ecology and biology of disease transmission were transforming. Changing understandings led to conflicts over the appropriate response. Medical and government authorities employed symbols like dirt to address gaps in knowledge. They used these symbols strategically to compel emotional responses and to advocate for specific political and social interventions, authorising institutional actions to shape social identity and the city in preparation for Australia's 1901 Federation. Through theoretical and historical (...) analysis, this Element argues that disgust and aversion were effectively mobilised to legitimise these actions. As an intervention in contemporary debates about the impact of knowledge on emotion and affect, it presents a case for the plasticity of emotions like disgust, and for how both emotion and affect can change with new medical information.

A deeply personal reckoning with family, mental illness, and suicide, Dana Trusso captures the meaning of Nietzsche's armor fati--to love one's fate--through her surreal imagery and longing to heal intergenerational wounds. Lines are drawn from Lars von Trier's Melancholia, Sonic Youth's Experimental Jet Set, Trash and No Star, and lines she read from her aunt's journals as a child. -/- The photo is a sculpture of an earth goddess by Jean-Philippe Richard located in the botanical gardens of Èze, France. Nearby (...) is Le Chemin de Nietzsche, a steep hike from the seaside to mountainous ruins that is said to have inspired Thus Spoke Zarathustra. (shrink)

Note: Paper to appear in special issue of the journal Psychology of Consciousness: Theory, Research, and Practice, on the evolution of consciousness //// Klein, Nguyen, & Zhang (in press) argued that the evolutionary transition from respondent to agent during the Cambrian Explosion would be a promising vantage point from which to gain insight into the evolution of organic sentience. They focused on how increased competition for resources -- in consequence of the proliferation of new, neurally sophisticated life-forms -- made awareness (...) of the external world (in the service of agentic acts) an adaptive priority. The explanatory scope of Klein et al (in press) was limited to consideration of the conscious apprehension of externally sourced content – i.e., content delivered from the sensory registration of objects occupying phenomenal space. But consciousness – at least for humans -- takes its objects from internal as well as external sources. In the present article we extend their analysis to the question of how internally sourced content (i.e., mental states) became the object of conscious apprehension. (shrink)

I attribute to Aristotle a theory of sensible qualities that straddles the modern debate between reductive physicalist and primitivist theories of color. On the interpretation I defend, Aristotle identifies sensible qualities with the physical properties of sensibly qualified bodies in virtue of which they move and affect perceivers and sense media. Nevertheless, I argue, Aristotle thinks that the essential nature of these qualities is revealed in ordinary sense experience. From a modern perspective, the resulting picture of sensible qualities as simultaneously (...) causes and manifest features of sense experience appears naive. But as I hope to show, it is in fact the product of an explanatorily sophisticated scientific theory, one which Aristotle finds necessary to meet the complex demands that, for him, make sensible qualities an ontological problem.

Extensive and critical review of Perception and Reality in Kant, Husserl and McDowell, written by van Mazijk, Corijn focussing on his discussion of McDowell.

Doxastic involuntarism—the thesis that we lack direct voluntary control (in response to non-evidential reasons) over our belief states—is often touted as philosophical orthodoxy. I here offer a novel defense of doxastic voluntarism, centered around three key moves. First, I point out that belief has two central functional roles, but that discussions of voluntarism have largely ignored questions of control over belief's guidance function. Second, I propose that we can learn much about doxastic control by looking to cognitive scientific research on (...) control over other relevantly similar mental states. I draw on a mechanistic account of control of the guidance function for “emotion-type states,” and argue that these same cognitive control mechanisms can used to block doxastic guidance. This gives us an account of “back-end” doxastic control which can be deployed for reasons which are not the right kinds of reasons to support “front-end” belief formation—i.e., non-evidential reasons. Third, I argue that comprehensive, self-directed exercises of this kind of control can amount to an underappreciated kind of voluntarism. This form of voluntarism is available to any account of belief that takes guidance-instantiation to be at least partly constitutive of believing. Finally, I discuss objections to, and upshots of, the view. (shrink)
