This paper distinguishes between synchronic responsibility (SR) and diachronic responsibility (DR). SR concerns an agent’s responsibility for an act at the time of the action, while DR concerns an agent’s responsibility for an act at some later time. While most theorists implicitly assume that DR is a straightforward matter of personal identity, I argue instead that it is grounded in psychological connectedness. I discuss the implications this distinction has for the concepts of apology, forgiveness, and punishment as well (...) as the way in which this distinction can be used to defend quality of will accounts of responsibility against objections involving psychological manipulation. I argue that the intuition that a manipulated agent is not responsible can be explained by appeal to the conditions of DR and, as such, does not unproblematically shed light on the conditions of SR.

This paper explicates two notions of emergencewhich are based on two ways of distinguishinglevels of properties for dynamical systems.Once the levels are defined, the strategies ofcharacterizing the relation of higher level to lower levelproperties as diachronic and synchronic emergenceare the same. In each case, the higher level properties aresaid to be emergent if they are novel or irreducible with respect to the lower level properties. Novelty andirreducibility are given precise meanings in terms of the effectsthat the change of a (...) bifurcation or perturbation parameterin the system has. (The same strategy can be applied to otherways of separating levels of properties, like themicro/macro distinction.)The notions of emergence developed here are notions of emergencein a weak sense: the higher level emergent properties wecapture are always structural properties (or are realized insuch properties), that is, they are defined in terms of the lowerlevel properties and their relations. Diachronic and synchronicemergent properties are distinctions within thecategory of structural properties. (shrink)

We briefly review the long-standing ideas about the use of synchronicity in the brain, which rely on Donald Hebb's views on cell assemblies and synaptic plasticity. More recently the distinction among several timescales in the description of neural activity has become a focus of theoretical discussion. Phillips & Singer's target article is criticized mainly because it does not distinguish these timescales properly and hence does not really address the questions so intensely debated today.

Objectives: Machine learning (ML) has the potential to facilitate “continual learning” in medicine, in which an ML system continues to evolve in response to exposure to new data over time, even after being deployed in a clinical setting. In this article, we provide a tutorial on the range of ethical issues raised by the use of such “adaptive” ML systems in medicine that have, thus far, been neglected in the literature. -/- Target audience: The target audiences for this tutorial are (...) the developers of ML AI systems, healthcare regulators, the broader medical informatics community, and practicing clinicians. -/- Scope: Discussions of adaptive ML systems to date have overlooked the distinction between 2 sorts of variance that such systems may exhibit—diachronic evolution (change over time) and synchronic variation (difference between cotemporaneous instantiations of the algorithm at different sites)—and underestimated the significance of the latter. We highlight the challenges that diachronic evolution and synchronic variation present for the quality of patient care, informed consent, and equity, and discuss the complex ethical trade-offs involved in the design of such systems.

Taking ontological realism about social groups as the thesis that groups are composite material objects constituted by their members, this paper considers a challenge to the very possibility that groups be regarded as material entities. Ordinarily we believe that two groups can have synchronic co-extensive memberships—for example, the choir and the rugby team—while preserving their distinctive identity conditions. We also doubt that two objects of the same kind can be in the same place at the same time, which would (...) appear to be the case when groups have identical memberships. I explain that the principle denying the synchronic co-location of objects of the same kind need not apply universally to material objects and that it is a mistake to take resistance to penetrability as a necessary feature of materiality. Therefore, initial appearances notwithstanding, groups can be in the same place at the same time. Key Words: identity • materiality • location • social group. (shrink)

This book is the first collective volume specifically devoted to the multifaceted phenomenon of intensification, which has been traditionally regarded as related to the expression of degree, scaling a quality downwards or upwards. In spite of the large amount of studies on intensifiers, there is still a need for the characterization of intensification as a distinct functional category in the domain of modification. The eighteen papers of the volume contribute to this aim with a new approach (mainly corpus-based). They focus (...) on intensification from different perspectives (both synchronic and diachronic) and theoretical frameworks, concern ancient languages (Hittite, Greek, Latin) and modern languages (mainly Italian, German, English, Kiswahili), and involve different levels of analysis. They also identify and examine different types of intensifiers, applied to different forms and structures, such as adverbs, adjectives, evaluative affixes, discourse markers, reduplication, exclamative clauses, coordination, prosodic elements, and shed light on issues which have not been extensively studied so far.

How do our brains represent distinct objects in consciousness? In order to consciously distinguish between objects, our brains somehow selectively bind together activity patterns of spatially intermingled neurons that simultaneously represent similar and dissimilar features of distinct objects. Gamma-band synchronous oscillations of neuroelectrical activity have been hypothesized to be a mechanism used by our brains to generate and bind conscious sensations to represent distinct objects. Most experiments relating GSO to specific features of consciousness have been published only in the last (...) several years. This brief review focuses on a wide variety experiments in which animals, including humans, discriminate between sensory stimuli and make these discriminations evident in their behavior. Performance of these tasks, in humans, is invariably accompanied by conscious awareness of both stimuli and behavior. Results of these experiments indicate that specific patterns of GSO correlate closely with specific aspects of conscious sensorimotor processing. That is, GSO appear to be closely correlated with neural generation of our most paradigmatic cognitive state: consciousness. (shrink)

The distinctions between A-series and B-series, between synchronic and diachronic identity and between perdurance and endurance are basic in the philosophy of time; yet they are flawed. McTaggart’s claim that the B-series is static and that a series has to be changing to be really temporal arises from a misunderstanding of temporal relations and of the task of ontological analysis. The dynamic appearance of the A-series results from the incompleteness of the analysis. “Synchronic identity” is synonymous with “strict (...) identity”, which has nothing to do with simultaneity. “Diachronic Identity” is another designation for persistence of an ordinary thing through time and change. Now, strict self-identity holds independently of whether a thing has a short or a long duration. Hence, diachronic identity is synchronic identity. Lewis’ distinguishes two kinds of ontological analyses of persistence, the perdurance and the endurance analysis. This dichotomy is in several respects not exhaustive. Above all, his definition of “persist” is inadequate being based on the notion of multiple temporal localisation which is apt with interrupted but misplaced with persistent, i.e., temporally continuous objects.

My paper has two aims: to underscore the importance of differently time-indexed ‘ought implies can’ principles; and to apply this to the culpable inability problem. Sometimes we make ourselves unable to do what we ought, but in those cases, we may still fail to do what we ought. This is taken to be a serious problem for synchronic ‘ought implies can’ principles, with a simultaneous ‘ought’ and ‘can’. Some take it to support diachronic ‘ought implies can’, with a potentially (...) temporally distinct ‘ought’ and ‘can’. I will argue that this problem is not avoided by diachronic ‘ought implies can’. (shrink)

We present in this paper a novel ontological theory of events whose central tenet is the Aristotelian distinction between the object that changes and the actual subject of change, which is what we call an individual quality. While in the Kimian tradition events are individuated by a triple ⟨ o, P, t ⟩, where o is an object, P a property, and t an interval of time, for us the simplest events are qualitative changes, individuated by a triple ⟨ (...) o, q, t ⟩, where q is an individual quality inhering in o or in one of its parts. Detaching the individuation of events from the property they exemplify results in a fine-grained theory that keeps metaphysics and semantics clearly separate, and lies between the multiplicative and the unitarian approaches. We discuss then the way language refers to events, observing that, in most cases, event descriptions refer to complex, cognitively relevant clusters of co-occurring qualitative changes, which exhibit a synchronic structure depending on the way they are described. Contra Bennett, who famously argued that the semantics of event names ultimately depends on “local context and unprincipled intuitions”, we show how the lexicon provides systematic principles for individuating such clusters and classifying them into kinds. Finally, we address some open challenges in the semantics of locative and manner modifiers. (shrink)

Recent philosophical discourse on emergence has developed with particular concern for the distinction between weak and strong emergence and with the primary focus on detailed analysis of the concept of supervenience. However, in the last decade and as a new departure, attention has been devoted to the distinction between synchronic and diachronic emergence. In this philosophical context, there is an ongoing general belief that these two concepts are so different that it is impossible to establish for them (...) a general unifying framework. It is the purpose of this paper to support an alternative view, i.e. that these concepts are different but not mutually exclusive, and that attending to appearance and persistence can, in this context, lead to an acceptable unifying framework for these two, differing concepts of emergence.

Tragedy and philosophy are two distinct forms of interpretation of the world, both developed at the same time in Greece: both are two aspects of a certain mindset of that historical period. The philosophy is systematically and historically successive to tragedy. The tragedy, however, is not only preceding the philosophy, but also accompanying its origin and even forming the contentual cause of philosophy. To illuminate this cause, it is necessary to understand the tragedy and the philosophy as a common (...) class='Hi'>distinction from that which precedes them and that they both seek to overcome: the myth. The reciprocal relationship of tragedy and philosophy can be described in the context of their common critique of the myth. At the same time, the phenomenon of tragedy is to be understood as a condition of philosophy, insofar the tragic is an expression of a mindset that allows philosophical thought. (shrink)

The distinction between ‘relational' and ‘distributive’ equality has come to play an important role in discussions of equality and justice. But the nature of the distinction is not as clear as we might hope. In this regard, Juliana Bidadanure makes an interesting and important proposal: the two views involve differing kinds of temporal concern. The distributive approach, she suggests, is concerned with equality over people’s complete lives (diachronic equality), whereas the relational approach is concerned with egalitarian social relations (...) at each moment in time (synchronic equality). I argue that this suggestion, while insightful, is not entirely satisfactory. Both relational and distributive equality, I demonstrate, have diachronic and synchronic aspects. Nonetheless, they do so in distinctive ways. So, while the diachronic/synchronic distinction does not provide a clean cut between relational and distributive equality, examining the temporal aspects of each approach helps to illuminate their distinctiveness.

(Note: the posted version of this paper is undergoing non-trivial revision; an updated version will be posted in June 2024.) Is there a need for a distinctively diachronic conception of metaphysical emergence? Here I argue to the contrary. In the main, my strategy consists in considering a representative sample of accounts of purportedly diachronic metaphysical emergence, and arguing that in each case, the purportedly diachronic emergence at issue either can (and should) be subsumed under a broadly synchronic account of (...) metaphysical emergence, or else is better seen as simply a case of causation. In addition, I consider and argue against the suggestion that 'in-principle unpredictability' accounts of diachronic emergence support there being distinctively diachronic metaphysical emergence.

I advocate Time-Slice Rationality, the thesis that the relationship between two time-slices of the same person is not importantly different, for purposes of rational evaluation, from the relationship between time-slices of distinct persons. The locus of rationality, so to speak, is the time-slice rather than the temporally extended agent. This claim is motivated by consideration of puzzle cases for personal identity over time and by a very moderate form of internalism about rationality. Time-Slice Rationality conflicts with two proposed principles of (...) rationality, Conditionalization and Reflection. Conditionalization is a diachronic norm saying how your current degrees of belief should fit with your old ones, while Reflection is a norm enjoining you to defer to the degrees of belief that you expect to have in the future. But they are independently problematic and should be replaced by improved, time-slice-centric principles. Conditionalization should be replaced by a synchronic norm saying what degrees of belief you ought to have given your current evidence and Reflection should be replaced by a norm which instructs you to defer to the degrees of belief of agents you take to be experts. These replacement principles do all the work that the old principles were supposed to do while avoiding their problems. In this way, Time-Slice Rationality puts the theory of rationality on firmer foundations and yields better norms than alternative, non-time-slice-centric approaches. (shrink)

After setting out in part 1 Scotus's libertarian account of the will, I shall discuss two of the most important implications Scotus understood his account to have. First, according to Scotus, the Thomist understanding of the will as intellective appetite is inadequate to provide a libertarian account of freedom. Scotus therefore rejects that understanding and offers an alternative moral psychology. In part 2 of the paper I therefore draw attention to the passages in which Scotus offers his reasons for rejecting (...) Aquinas's account in order to show that they arise directly out of the libertarian account of the will I stated in part 1. I then ask whether Scotus is in fact justified in supposing that Aquinas's conception of will is incompatible with freedom as Scotus understood it. In parts 3 and 4 of the paper I shall argue that he is, since Aquinas's conception of possibility at best allows him to make room for diachronic alternatives, whereas Scotus insists on synchronic alternatives. -/- The second implication of Scotus's libertarian understanding of freedom is his distinctive conception of choice and of rationality in action. In part 5 of the paper I explain this conception and show why Scotus associates it with a libertarian understanding of freedom. (shrink)

Mechanistic approaches are very common in the causal interpretation of biological and neuroscientific experimental work in today’s philosophy of science. In the mechanistic literature a strict distinction is often made between causal relations and constitutive relations, where the latter cannot be causal. One of the typical reasons for this strict distinction is that constitutive relations are supposedly synchronic whereas most if not all causal relations are diachronic. This strict distinction gives rise to a number of problems, (...) however. Our end goal in this paper is to argue that it should be given up, at least in the context of the biological and the psychological sciences. To that effect, we argue that constitutive relations in this context are diachronic, thus undermining the aforementioned reason. We offer two cases from scientific practice in which constitutive relations are regarded as both diachronic and causally efficacious, review three existing ways of dealing with the apparent diachronic nature of interlevel relations in mechanisms and propose a new account of diachronic, causal constitutive relevance.

In this essay, I aim to address the two related problems faced by ontological emergence and propose a solution. First, I shall briefly outline the concept of emergence, the distinction between ontological and epistemological emergence, as well as the distinction between synchronic and diachronic emergence, and focus mainly on synchronic ontological emergence. Second, I shall discuss the two related problems faced by synchronic ontological emergence—configurational forces and downward causation. Third, I shall present a solution to (...) these problems—affirming ontological emergence but denying vertical causation. Last, I shall address objections to the ontological emergence without vertical causation view. (shrink)

Synchronous oscillations are ubiquitous throughout the cortex, but the frequency of oscillations differs from area to area. To elucidate the mechanistic architectures underlying various rhythmic activities, we tested whether spontaneous neural oscillations in different local cortical areas and large-scale networks can be phase-entrained by direct perturbation with distinct frequencies of repetitive transcranial magnetic stimulation. While recording the electroencephalogram, we applied single-pulse TMS and rTMS at 5, 11, and 23 Hz over the motor or visual cortex. We assessed local and global (...) modulation of phase dynamics using the phase-locking factor. sp-TMS to the motor and the visual cortex triggered a transient increase in PLF in distinct frequencies that peaked at 21 and 8 Hz, respectively. rTMS at 23 Hz over the motor cortex and 11 Hz over the visual cortex induced a prominent and progressive increase in PLF that lasted for a few cycles after the termination of rTMS. Moreover, the local increase in PLF propagated to other cortical areas. These results suggest that distinct cortical areas have area-specific oscillatory frequencies, and the manipulation of oscillations in local areas impacts other areas through the large-scale oscillatory network with the corresponding frequency specificity. We speculate that rTMS that is close to area-specific frequencies enables direct manipulation of brain dynamics and is thus useful for investigating the causal roles of synchronous neural oscillations. Moreover, this technique could be used to treat clinical symptoms associated with impaired oscillations and synchrony. (shrink)

My aim is to propose affectivity as a criterion for personal identity. My proposal is to be taken in its weak version: affectivity as _only one_ of the criteria for personal identity. I start by arguing for affectivity being a better candidate as a criterion for personal identity than thinking. Next, I focus on synchronic vs. diachronic and on ontic vs. epistemic distinctions (my proposal will concern diachronic ontic personal identity) and consider the realm of affectivity in its temporal (...) dimension. In my argument, I rely on the genuineness of affectivity and I exploit chiefly long- or everlasting feelings (or emotions) and those which involve the feeling subject more rather than less. I conclude by stating that genuine long-lasting feelings (or emotions) are constitutive of diachronic ontic personal identity. (shrink)

This paper makes a distinction between ahistorical causal-functional kinds and historical kinds, which include both type- and token-historical kinds, some of which are “copied kinds.” After showing how these distinctions play out in various social sciences, a number of reasons are put forward for the historical individuation of some social kinds. As in the natural sciences, historical individuation in the social sciences can enable us to infer common causes, explain synchronic causal properties, and discover exceptions to causal regularities, (...) among other epistemic aims.

A family of recent externalist approaches in philosophy of mind argues that our psychological capacities are synchronically and diachronically “scaffolded” by external resources. I consider how these “scaffolded” approaches might inform debates in phenomenological psychopathology. I first introduce the idea of “affective scaffolding” and make some taxonomic distinctions. Next, I use schizophrenia as a case study to argue—along with others in phenomenological psychopathology—that schizophrenia is fundamentally a self-disturbance. However, I offer a subtle reconfiguration of these approaches. I argue that schizophrenia (...) is not simply a disruption of ipseity or minimal self-consciousness but rather a disruption of the scaffolded self, established and regulated via its ongoing engagement with the world and others. I conclude by considering how this scaffolded framework indicates the need to consider new forms of intervention and treatment. (shrink)

We investigated how motor agency in the voluntary control of body movement influences body awareness. In the Rubber Hand Illusion , synchronous tactile stimulation of a rubber hand and the participant’s hand leads to a feeling of the rubber hand being incorporated in the participant’s own body. One quantifiable behavioural correlate of the illusion is an induced shift in the perceived location of the participant’s hand towards the rubber hand. Previous studies showed that the induced changes in body awareness are (...) local and fragmented: the proprioceptive drift is largely restricted to the stimulated finger. In the present study, we investigated whether active and passive movements, rather than tactile stimulation, would lead to similarly fragmented body awareness. Participants watched a projected image of their hand under three conditions: active finger movement, passive finger movement, and tactile stimulation. Visual feedback was either synchronous or asynchronous with respect to stimulation of the hand. A significant overall RHI, defined as greater drifts following synchronous than asynchronous stimulation, was found in all cases. However, the distribution of the RHI across stimulated and non-stimulated fingers depended on the kind of stimulation. Localised proprioceptive drifts, specific to the stimulated finger, were found for tactile and passive stimulation. Conversely, during active movement of a single digit, the proprioceptive drifts were not localised to that digit, but were spread across the whole hand. Whereas a purely proprioceptive sense of body-ownership is local and fragmented, the motor sense of agency integrates distinct body-parts into a coherent, unified awareness of the body. (shrink)

Deep brain stimulation has been of considerable interest to bioethicists, in large part because of the effects that the intervention can occasionally have on central features of the recipient’s personality. These effects raise questions regarding the philosophical concept of authenticity. In this article, we expand on our earlier work on the concept of authenticity in the context of deep brain stimulation by developing a diachronic, value-based account of authenticity. Our account draws on both existentialist and essentialist approaches to authenticity, and (...) Laura Waddell Ekstrom’s coherentist approach to personal autonomy. In developing our account, we respond to Sven Nyholm and Elizabeth O’Neill’s synchronic approach to authenticity, and explain how the diachronic approach we defend can have practical utility, contrary to Alexandre Erler and Tony Hope’s criticism of autonomy-based approaches to authenticity. Having drawn a distinction between the authenticity of an individual’s traits and the authenticity of that person’s values, we consider how our conception of authenticity applies to the context of anorexia nervosa in comparison to other prominent accounts of authenticity. We conclude with some reflections on the prudential value of authenticity, and by highlighting how the language of authenticity can be invoked to justify covert forms of paternalism that run contrary to the value of individuality that seems to be at the heart of authenticity.

Motivated by the seeming structure of the sciences, metaphysical emergence combines broadly synchronic dependence coupled with some degree of ontological and causal autonomy. Reflecting the diverse, frequently incompatible interpretations of the notions of dependence and autonomy, however, accounts of emergence diverge into a bewildering variety. Here I argue that much of this apparent diversity is superficial. I first argue, by attention to the problem of higher-level causation, that two and only two strategies for addressing this problem accommodate the genuine (...) emergence of special science entities. These strategies in turn suggest two distinct schema for metaphysical emergence---'Weak' and 'Strong' emergence, respectively. Each schema imposes a condition on the powers of entities taken to be emergent: Strong emergence requires that higher-level features have more token powers than their dependence base features, whereas Weak emergence requires that higher-level features have a proper subset of the token powers of their dependence base features. Importantly, the notion of “power” at issue here is metaphysically neutral, primarily reflecting commitment just to the plausible thesis that what causes an entity may bring about are associated with how the entity is---that is, with its features.

Decisions are made under uncertainty when there are distinct outcomes of a given action, and one is uncertain to which the act will lead. Decisions are made under indeterminacy when there are distinct outcomes of a given action, and it is indeterminate to which the act will lead. This paper develops a theory of (synchronic and diachronic) decision-making under indeterminacy that portrays the rational response to such situations as inconstant. Rational agents have to capriciously and randomly choose how to (...) resolve the indeterminacy relevant to a given choice-situation, but such capricious choices once made constrain how they will choose in the future. The account is illustrated by the case of self-interested action in situations where it is indeterminate whether you yourself will survive to benefit or suffer the consequences. The conclusion emphasizes some distinctive anti-hedging predictions of the account. (shrink)

Empathy means understanding another person’s emotional or intentional state by vicariously sharing this state. As opposed to emotional contagion, empathy is characterized by the self–other distinction of subjective experience. Empathy develops in the second year, as soon as symbolic representation and mental imagery set in that enable children to represent the self, to recognize their mirror image, and to identify with another person. In experiments with 126 children, mirror recognition and readiness to empathize with a distressed playmate were investigated. (...)

In this article, I present two conceptual problems for Craver's mutual manipulability account of constitutive relevance in mechanisms. First, constitutive relevance threatens to imply causal relevance despite Craver (and Bechtel)'s claim that they are strictly distinct. Second, if (as is intuitively appealing) parthood is defined in terms of spatio-temporal inclusion, then the mutual manipulability account is prone to counterexamples, as I show by a case of endosymbiosis. I also present a methodological problem (a case of experimental underdetermination) and formulate two (...) partial, but fallible solutions based on the notions of parthood and synchronicity.

Self–other distinction, as documented by mirror self-recognition (MSR), allows for empathy which offers a motivational base for helping a person in need.

Due to the experimental setting, however, other releasers of children’s sadness and helping behavior have to be considered. An alternative setting is proposed. With respect to MSR, (...) the question of false negatives is discussed. The issues mentioned by Klann-Delius address fundamental theoretical questions that cannot be answered briefly. (shrink)

Mark Textor presents a critical study of the work of Franz Brentano, one of the most important thinkers of the nineteenth century. His work has influenced analytic philosophers like Russell as well as phenomenologists like Husserl and Sartre, and continues to shape debates in the philosophy of mind. Brentano made intentionality a central topic in the philosophy of mind by proposing that 'directedness' is the distinctive feature of the mental. The first part of the book investigates Brentano's intentionalism as well (...) as attempts to improve or develop it. Textor argues that there is no plausible version of this doctrine, and rejects it in favour of a mark of the mental proposed by Brentano's student Husserl: mental phenomena have no appearances. The second part of the book develops and defends Brentano's view about the structure of perceptual awareness. Awareness of a mental activity and this mental activity are not distinct mental acts, the first representing the second. They are one and the same activity that has several objects. Textor shows that Brentano held that intentionality is plural - directedness is directedness on some objects - and shows how the plural conception solves thorny problems. The third part of the book is devoted to Brentano's view of pleasure and pain. Textor draws out parallels between enjoying an activity and awareness of it and argues that enjoying an activity and the activity enjoyed are not distinct. The final part of the book extends the plural view to the conscious mental life of a thinker at a time (the unity of synchronic consciousness): it is one mental act with many objects. (shrink)

Evidentialism as Earl Conee and Richard Feldman present it is a philosophy with distinct aspects or sides: Evidentialism as a conceptual analysis of epistemic justification, and as a prescriptive ethics of belief. I argue that Conee and Feldman's ethics of belief has 'weak roots and sour fruits.' It has "weak roots" because it is premised on their account of epistemic justification qua synchronic rationality, and this is neither necessary nor sufficient for knowledge. Also, Conee and Feldman's thesis O2 (An (...) agent ought to always have just exactly that attitude towards a proposition supported by his / her evidence at that particular moment) is not support by in their “Ethics of Belief” article by V3 (Being synchronically rational at every moment is uniformly what it is to constitute epistemic success and to maximize epistemic value). That austere ethics of belief has "sour fruits" because the austere evidentialist ethic of belief is unable to support reasonable disagreement, and conflates psychographic contrareity epistemic fault or irrationality. The "hard line" and universal agnostic suspension it takes as the only rational stances of disagreement are really caricatures of different extreme responses to contrareity found among dogmatists and skeptics, respectively. I contrast this with John Rawls' understanding of "reasonable pluralism" and of the many sources of faultless disagreement over what Rawls termed comprehensive conceptions of the good. (shrink)

This article compares causal and constitutive explanation. While scientific inquiry usually addresses both causal and constitutive questions, making the distinction is crucial for a detailed understanding of scientific questions and their interrelations. These explanations have different kinds of explananda and they track different sorts of dependencies. Constitutive explanations do not address events or behaviors, but causal capacities. While there are some interesting relations between building and causal manipulation, causation and constitution are not to be confused. Constitution is a synchronous (...) and asymmetric relation between relata that cannot be conceived as independent existences. However, despite their metaphysical differences, the same key ideas about explanation largely apply to both. Causal and constitutive explanations face similar challenges (such as the problems of relevance and explanatory regress) and both are in the business of mapping networks of counterfactual dependence—i.e. mechanisms—although the relevant counterfactuals are of a different sort. In the final section the issue of developmental explanation is discussed. It is argued that developmental explanations deserve their own place in taxonomy of explanations, although ultimately developmental dependencies can be analyzed as combinations of causal and constitutive dependencies. Hence, causal and constitutive explanation are distinct, but not always completely separate forms of explanation. (shrink)

Numbers are concepts whose content, structure, and organization are influenced by the material forms used to represent and manipulate them. Indeed, as argued here, it is the inclusion of multiple forms (distributed objects, fingers, single- and two-dimensional forms like pebbles and abaci, and written notations) that is the mechanism of numerical elaboration. Further, variety in employed forms explains at least part of the synchronic and diachronic variability that exists between and within cultural number systems. Material forms also impart characteristics (...) like linearity that may persist in the form of knowledge and behaviors, ultimately yielding numerical concepts that are irreducible to and functionally independent of any particular form. Material devices used to represent and manipulate numbers also interact with language in ways that reinforce or contrast different aspects of numerical cognition. Not only does this interaction potentially explain some of the unique aspects of numerical language, it suggests that the two are complementary but ultimately distinct means of accessing numerical intuitions and insights. The potential inclusion of materiality in contemporary research in numerical cognition is advocated, both for its explanatory power, as well as its influence on psychological, behavioral, and linguistic aspects of numerical cognition.

Diachronic Dutch book arguments seem to support both conditionalization and Bas van Fraassen's Reflection principle. But the Reflection principle is vulnerable to numerous counterexamples. This essay addresses two questions: first, under what circumstances should an agent obey Reflection, and second, should the counterexamples to Reflection make us doubt the Dutch book for conditionalization? In response to the first question, this essay formulates a new "Qualified Reflection" principle, which states that an agent should obey Reflection only if he or she is (...) certain that he or she will conditionalize on veridical evidence in the future. Qualified Reflection follows from the probability calculus together with a few idealizing assumptions. The essay then formulates a "Distorted Reflection" principle that approximates Reflection even in cases where the agent is not quite certain that he or she will conditionalize on veridical evidence. In response to the second question, the essay argues that contrary to a common misconception, not all Dutch books dramatize incoherence—some dramatize a less blameworthy sort of epistemic frailty that the essay calls "self-doubt." The distinction between Dutch books that dramatize incoherence and those that dramatize self-doubt cross-cuts the distinction between synchronic and diachronic Dutch books. The essay explains why the Dutch book for conditionalization reveals true incoherence, whereas the Dutch book for Reflection reveals only self-doubt. (shrink)

How did the human brain evolve so that consciousness of art could develop? In The Psychology of Art and the Evolution of the Conscious Brain, Robert Solso describes how a consciousness that evolved for other purposes perceives and creates art.Drawing on his earlier book Cognition and the Visual Arts and ten years of new findings in cognitive research, Solso shows that consciousness developed gradually, with distinct components that evolved over time. One of these components is an adaptive consciousness that includes (...) the ability to imagine objects that are not present--an ability that allows us to create visual art.Solso describes the neurological, perceptual, and cognitive sequence that occurs when we view art, and the often inexpressible effect that a work of art has on us. He shows that there are two aspects to viewing art: nativistic perception--the synchronicity of eye and brain that transforms electromagnetic energy into neuro-chemical codes--which is "hard-wired" into the sensory-cognitive system; and directed perception, which incorporates personal history and knowledge--the entire set of our expectations and past experiences. Both forms of perception are part of the appreciation of art, and both are products of the evolution of the conscious brain over hundreds of thousands of years.Solso also investigates the related issues of neurological and artistic perception of the human face, the effects of visual illusions, and the use of perspective. The many works of art used as examples are drawn from a wide range of artistic traditions, from ancient Egypt to Africa and India and the European Renaissance. (shrink)

The goal of this article is to review some aspects of brain anatomy and neurophysiology that are important for consciousness, and which hopefully may be of benefit to philosophers investigating the conscious mind. Taking as an initial point of reference the distinction between “the hard problem” and “the weak problems” of consciousness, we shall concentrate on questions pertaining to the second of these. A putative “consciousness system” in the brain will be presented, paying special attention to diffuse projection systems. (...) The “center of gravity” will be brain connectivity, since consciousness must, critically, be dependent on coherent activity and timing. “Detectors” of synchronicity and coincidence, like NMDA receptors, also necessarily play a role here. To be conscious, we do not need an entire brain. While even large hemispherectomies need not unequivocally affect consciousness, far smaller brain-stem lesions may be devastating in this regard. Even so, the recent discovery by Matthew F. Glasser et al. of 180 separate areas in the human brain cortex is intriguing from a teleological perspective, as it is quite unthinkable that any of them could be “redundant. (shrink)

Body ownership concerns what it is like to feel a body part or a full body as mine, and has become a prominent area of study. We propose that there is a closely related type of bodily self-consciousness largely neglected by researchers—experiential ownership. It refers to the sense that I am the one who is having a conscious experience. Are body ownership and experiential ownership actually the same phenomenon or are they genuinely different? In our experiments, the participant watched a (...) rubber hand or someone else’s body from the first-person perspective and was touched either synchronously or asynchronously. The main findings: (1) The sense of body ownership was hindered in the asynchronous conditions of both the body-part and the full-body experiments. However, a strong sense of experiential ownership was observed in those conditions. (2) We found the opposite when the participants’ responses were measured after tactile stimulations had ceased for 5 s. In the synchronous conditions of another set of body-part and full-body experiments, only experiential ownership was blocked but not body ownership. These results demonstrate for the first time the double dissociation between body ownership and experiential ownership. Experiential ownership is indeed a distinct type of bodily self-consciousness.

How did the human brain evolve so that consciousness of art could develop? In The Psychology of Art and the Evolution of the Conscious Brain, Robert Solso describes how a consciousness that evolved for other purposes perceives and creates art.Drawing on his earlier book Cognition and the Visual Arts and ten years of new findings in cognitive research, Solso shows that consciousness developed gradually, with distinct components that evolved over time. One of these components is an adaptive consciousness that includes (...) the ability to imagine objects that are not present--an ability that allows us to create visual art.Solso describes the neurological, perceptual, and cognitive sequence that occurs when we view art, and the often inexpressible effect that a work of art has on us. He shows that there are two aspects to viewing art: nativistic perception--the synchronicity of eye and brain that transforms electromagnetic energy into neuro-chemical codes--which is "hard-wired" into the sensory-cognitive system; and directed perception, which incorporates personal history and knowledge--the entire set of our expectations and past experiences. Both forms of perception are part of the appreciation of art, and both are products of the evolution of the conscious brain over hundreds of thousands of years.Solso also investigates the related issues of neurological and artistic perception of the human face, the effects of visual illusions, and the use of perspective. The many works of art used as examples are drawn from a wide range of artistic traditions, from ancient Egypt to Africa and India and the European Renaissance. (shrink)

Pablo Gilabert and Holly Lawford-Smith have, both in collaboration and individually, provided a compelling account of feasibility, which states that feasibility is both ‘binary’ and ‘scalar’, and both ‘synchronic’ and ‘diachronic’. This two-dimensional analysis, however, has been the subject of four major criticisms: it has been argued that it rests upon a false distinction between ‘hard’ and ‘soft’ constraints, that it ignores the importance of intentional action, and that diachronic feasibility is incoherent and insensitive to the existence of (...) epistemic limitations. In this paper, I will argue that such objections do not undermine the persuasiveness of Gilabert and Lawford-Smith’s analysis. Nevertheless, I will contend that the latter is susceptible to two other challenges. First, it mistakenly appeals to morality, and, second, it lacks an analysis of ability. I will maintain, however, that such criticisms can be addressed and that a revised version of the account should be adopted. (shrink)

A general conceptual framework for large-scale neocortical dynamics based on data from many laboratories is applied to a variety of experimental designs, spatial scales, and brain states. Partly distinct, but interacting local processes (e.g., neural networks) arise from functional segregation. Global processes arise from functional integration and can facilitate (top down) synchronous activity in remote cell groups that function simultaneously at several different spatial scales. Simultaneous local processes may help drive (bottom up) macroscopic global dynamics observed with electroencephalography (EEG) or (...) magnetoencephalography (MEG). A local/global dynamic theory that is consistent with EEG data and the proposed conceptual framework is outlined. This theory is neutral about properties of neural networks embedded in macroscopic fields, but its global component makes several qualitative and semiquantitative predictions about EEG measures of traveling and standing wave phenomena. A more general “metatheory” suggests what large-scale quantitative theories of neocortical dynamics may be like when more accurate treatment of local and nonlinear effects is achieved. The theory describes the dynamics of excitatory and inhibitory synaptic action fields. EEG and MEG provide large-scale estimates of modulation of these synaptic fields around background levels. Brain states are determined by neuromodulatory control parameters. Purely local states are dominated by local feedback gains and rise and decay times of postsynaptic potentials. Dominant local frequencies vary with brain region. Other states are purely global, with moderate to high coherence over large distances. Multiple global mode frequencies arise from a combination of delays in corticocortical axons and neocortical boundary conditions. Global frequencies are identical in all cortical regions, but most states involve dynamic interactions between local networks and the global system. EEG frequencies may involve a “matching” of local resonant frequencies with one or more of the many, closely spaced global frequencies. Key Words: binding problem; cell assemblies; coherence; EEG; limit cycles; neocortical dynamics; pacemakers; phase locking; spatial scale; standing waves; synchronization.

Mary Shepherd (1777–1847) was a fierce and brilliant critic of Berkeley and Hume, who moreover offered strikingly original positive views about the nature of reality and our access to it which deserve much more attention (and credit, since she anticipates many prominent views) than they have received thus far. By way of illustration, I focus on Shepherd's 1824 Essay Upon the Relation of Cause and Effect, Controverting the Doctrine of Mr. Hume, Concerning the Nature of that Relation (ERCE). After a (...) brief setup, I canvas certain of her trenchant objections to Hume’s argumentation; I then present the positive core of her response to Hume, which consists in providing novel accounts of how reason alone or reason coupled with experience can justify, first, that every effect must have a cause, and second, that it is necessary that like causes produce like effects. Among other contributions here, Shepherd provides a distinctively metaphysical argument for the claim that nothing can begin to exist 'of itself' (going beyond an appeal to the Principle of Sufficient Reason, in particular), and leverages difference-making considerations to make the case that a single 'experimentum crucis' can justify causal belief (anticipating Mill's 'method of difference'). I close by highlighting salient features of Shepherd's metaphysics of causation, whereby causation is singularist and local (anticipating Ducasse and Anscombe) and involves synchronic interactions (anticipating Mill's and certain contemporary accounts), and according to which objects are essentially characterized by their causes and effects (anticipating contemporary causal or dispositional essentialist positions).

Some habits are vital to who we are in that they shape both our self-perception and how we are seen by others. This is so, I argue, because there is a constitutive link between what I shall call ‘identity-shaping habits’ and narrative agency. Identity-shaping habits are paradigmatically acquired and performed by persons. The ontology of personhood involves both synchronic and diachronic dimensions which are structurally analogous to the synchronic acquisition and the diachronic performance of habits, and makes persons (...) distinctly suitable to being shaped by habits. Since habits differ vastly in their scope, I develop a conceptualization that carves out defining features of identity-shaping habits. Such habits, I venture, fundamentally alter a person’s embodiment such that the alterations to their psychological and physiological make-up vitally inform their persistence—if not metaphysically, then at least practically by crucially shaping one’s narrative agency.

In this paper, I discuss whether there are genuinely *diachronic* constraints of practical rationality, that is, pressures on combinations of practical attitudes over time, which are not reducible to mere synchronic rational pressures. Michael Bratman has recently argued that there is at least one such diachronic rational constraint that governs the stability of intentions over time. *Pace* Bratman, I argue that there are no genuinely diachronic constraints on intentions that meet the stringent desiderata set by him. But I show (...) that there are at least two synchronic rational constraints with distinctive and important, although only indirect, diachronic dimensions. Neither of them, however, supports the practical conservatism in the face of normative underdetermination that, according to Bratman, is part and parcel of the diachronic rationality of intention stability.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 38.4 (2000) 479-502 [Access article in PDF] Possible Worlds in the Tahâfut al-Falâsifa Al-Ghazâlî on Creation and Contingency Taneli Kukkonen University of Helsinki 1. This article is the second half in an inquiry into the debate between al-Ghazâlî (1058-1111) and Averroes (1126-1198) on the metaphysical basis of modalities. The first article focused on Averroes' exposition of the Arabic Aristotelian position on the eternity (...) of the world and the modalities, as found in the Tahâfut al-tahâfut, the "Incoherence of the Incoherence [of the Philosophers]" from ca. 1180.1 In this paper I propose to sketch the outlines to a very different conception suggested by al-Ghazâlî in the Tahâfut al-falâsifa (1095) and quoted verbatim and commented upon by Averroes in the Tahâfut al-tahâfut.2 In contrast to the naturalistic model of modalities propounded by [End Page 479] Averroes, al-Ghazâlî develops an interpretation of possibility in which conceivability and co-assertability are central. In several key respects al-Ghazâlî's approach mirrors that of John Duns Scotus in the fourteenth century: it makes possible, for instance, a distinction between conceptual and natural possibilities in a manner reminiscent of later Latin medieval theory, and, reflecting this, a distinction between the (non-temporal) moments of conception and causation in the divine mind. The parallels between al-Ghazâlî's and Augustine's basic conceptions, meanwhile, highlight the theological motives lying at the heart of the new thinking.As in the previous article, the dialectical form of Averroes' later Tahâfut al-tahâfut is used for critical insight. Averroes' criticism of al-Ghazâlî's modal theoretical innovations gives rise to an important question about the lengths to which al-Ghazâlî's proposals could be taken. The issue is to an extent unresolveable; one would do well to note why. Whereas Averroes' formulations in the Tahâfut al-tahâfut are made readily understandable against the backdrop of his Aristotelian commentaries and wider systematic teaching, it is less easy to determine how far al-Ghazâlî is willing to develop his own ideas. The materials given in the Tahâfut al-falâsifa leave the impression of being inconclusive and open-ended—perhaps deliberately so—and the ambiguities are mirrored in al-Ghazâlî's other texts.3Taken as they stand, al-Ghazâlî's formulations retain a substantial Avicennian residue, for better or for worse. This makes for a curious mixture of old and new in his overall scheme, a feature which Averroes can exploit by criticizing al-Ghazâlî from a strict Aristotelian viewpoint (just as he criticized Avicenna), while all the time maintaining that his adversary's proposals do not add up to a coherent and full-bodied alternative to that venerable tradition. But Averroes' criticisms do not touch on the way al-Ghazâlî's suggestions, vague as they may be, do represent a genuine breakthrough. Al-Ghazâlî's interpretation of the modal terms bypasses the connection traditionally made between true possibility and temporal instantiation. This allows for a freer handling of counterfactual possibilities, an important feature in any refiguring of the limits of possibility. 2. Al-Ghazâlî's innovations have their root in the idea of God freely choosing (arbitrating) between alternatives equal to him. This simple kernel of an idea, seated in the kalâm conception of possibility, allows for a recognition of the genuineness of synchronic alternatives: a seemingly small shift, but all-important [End Page 480] to the ensuing debate. Al-Ghazâlî has defended the notion of God's genuine choice earlier,4 but in refuting "the third proof of the philosophers for the world's eternity," he begins to make systematic use of the notion of possibility. A brief recapitulation of the philosophers' argument will serve to recall the reasoning from which al-Ghazâlî takes his cue. The philosophers, in al-Ghazâlî's words, had... (shrink)

Chapter 1 serves as an introduction to the vast topic of laws of nature. Thus, it first outlines the alleged characteristics of the laws of nature, namely truth, objectivity, contingency, necessity, universality, grounding counterfactuals and their role in science. Among these aspects, the peculiar modal status of laws of nature will be identified as the ‘holy grail’ of the debate. The second part of this chapter is concerned with the three main families of theories of laws of nature – neo-humean, (...) ADT and dispositional theories – which are introduced and evaluated in regard to the aforementioned characteristics. It will then be argued that among those theories, the dispositional ones show the greatest promise of being able to account for the natural necessity of the laws of nature. -/- Before a dispositional account of laws of nature can be given, dispositions themselves need to be understood. Consequently, Chapter 2 introduces various analyses of dispositions. As dispositions are pre-theoretically close to conditionals, a lot of analyses try to reduce dispositions to conditionals. This chapter critically assesses some chosen accounts: the simple conditional analysis, Carnap’s reduction sentences, the simple counterfactual conditional analysis, Lewis’ reformed conditional analysis, Malzkorn’s sophisticated con- ditional analysis, Choi and Gundersen’s context-dependent analysis, Manley and Wasserman’s gradable dispostion ascriptions, and Fara’s habituals. The prevention problem, which poses a threat to any account of dispositions, is depicted. It is argued that, ultimately, none of the conditionalising attempts is able to convince since they all exclude the problem cases which leads to explanation gaps and outlaw areas. -/- Chapter 3 contains the synchronic part of my preferred solution to the prevention problem. The notion of ‘component causes’ is introduced, and the ontological status of components discussed. Millikan’s oil drop experiment is depicted en detail. In a first step, making a distinction between dispositions and the resulting behaviour is advocated. Via the symmetry argument, mani- festations and masks are shown to be ontologically on a par. In a second step, a triadic account consisting of dispositions, wirkungen and resultant behaviour, is established. Finally, the ontological interpretation of the trias is given. It is in the nature of the dispositions to bring about the wirkungen. These interact via combinations rules like the functions f and fa or vector addition, which are built-in into to dispositions. -/- The diachronic part of my favourite interpretation, the triadic process picture of dispositions (TPD), is presented in chapter 4. The dynamics of dispo- sition manifestation are discussed and it is argued that fiddling with the trigger works only up to a certain point. Diachronic masking cases turn out to be no- torious. An excursus to action theory shows that the ontology needs to include processes, as understanding disposition manifestations as processes solves the diachronic prevention problem. The (TPD) can account for all counterexamples by taking the stimulus as the beginning of the manifestation process. -/- Chapter 5 applies the (TPD) to the debate about laws of nature. In order to judge its adequacy, the characteristics of laws of nature given in chapter 1 are consulted. As a first step, the criteria truth, objectivity, universality, grounding counterfactuals and their role in science are covered. It is sketched how the (TPD) can account for these. The second part of the chapter deals with the modal status of the laws of nature. The dispositional essentialist’s view that laws of nature are metaphysical necessary is depicted and then criticised. It is argued that metaphysical necessity is not the appropriate modal status of the laws of nature. Finally, the (TPD) account of the necessity of the laws of nature is presented: laws of nature are naturally necessary and metaphysically contingent. (shrink)

Rescorla explores the relation between Reflection, Conditionalization, and Dutch book arguments in the presence of a weakened concept of sure loss and weakened conditions of self‐transparency for doxastic agents. The literature about Reflection and about Dutch Book arguments, though overlapping, are distinct, and its history illuminates the import of Rescorla's investigation. With examples from a previous debate in the 70s and results about Reflection and Conditionalization in the 80s, I propose a way of seeing the epistemic enterprise in the light (...) of practical requirements to be met by demands for synchronic coherence and probability updating policies. This includes a defense of principles rejected by Rescorla, while allowing for the value of his results in the borderland between theories of cognition and formal epistemology. (shrink)

This paper examines the application of the mutual manipulability criterion as a way to demarcate constituents of cognitive systems from resources having a mere causal influence on cognitive systems. In particular, it is argued that on at least one interpretation of the mutual manipulability criterion, the criterion is inadequate because the criterion is conceptualized as identifying synchronic dependence between higher and lower ‘levels’ in mechanisms. It is argued that there is a second articulation of the mutual manipulability criterion available, (...) and that it should be preferred for at least two reasons. The first is that the criterion of mutual manipulability is an instance of continuous reciprocal causation. The second is that it has implications for how to understand this distinction between causation and constitution. It is shown that when considering dynamic systems, continuous reciprocal causation - ubiquitous in dynamical systems - is a form of constitutive causality, which entails that causal factors may, in the right circumstances, by genuine constitutive factors of cognition. This notion of constitutive causality lends support to conceiving of the mutual manipulability criterion as a genuine demarcation principle in the debate over the boundaries of mind. (shrink)
