Ensemble perception—the encoding of objects by their group properties—is known to be resistant to outlier noise. However, this resistance is somewhat paradoxical: how can the visual system determine which stimuli are outliers without already having derived statistical properties of the ensemble? A simple solution would be that ensemble perception is not a simple, one-step process; instead, outliers are detected through iterative computations that identify items with high deviance from the mean and reduce their weight in the representation over time. Here (...) we tested this hypothesis. In Experiment 1, we found evidence that outliers are discounted from mean orientation judgments, extending previous results from ensemble face perception. In Experiment 2, we tested the timing of outlier rejection by having participants perform speeded judgments of sets with or without outliers. We observed significant increases in reaction time (RT) when outliers were present, but a decrease compared to no-outlier sets of matched range suggesting that range alone did not drive RTs. In Experiment 3 we tested the timing by which outlier noise reduces over time. We presented sets for variable exposure durations and found that noise decreases linearly over time. Altogether these results suggest that ensemble representations are optimized through iterative computations aimed at reducing noise. The finding that ensemble perception is an iterative process provides a useful framework for understanding contextual effects on ensemble perception. (shrink)

This paper examines Steve Biko’s distinction between black and non-white as a project in the “amelioration” of social concepts and categories. Biko himself—it has been persuasively argued by Mabogo More and Lewis Gordon—writes in the tradition of existential phenomenology. More and Gordon explore Biko’s continuity with Frantz Fanon, and in this paper I draw on their interpretations, attempting to complement and elaborate on these continuities. I also, however, attempt to show how Biko moves beyond Fanon in crucial ways, (...) solving problems that Fanon confronted. By examining Fanon’s and Biko’s categories in light of recent work in social metaphysics, I explore the ways Biko attempts to transform an existing set of oppressive social categories in the world into new social categories.

Gordon Barnes accuses Robert Nozick and Eric Mack of neglecting, in two ways, the practical, empirical questions relevant to justice in the real world.1 He thinks these omissions show that the argument behind the Wilt Chamberlain example—which Nozick famously made in his seminal Anarchy, State, and Utopia—fails. As a result, he suggests that libertarians should concede that this argument fails. In this article, we show that Barnes’s key arguments hinge on misunderstandings of, or failures to notice, key aspects (...) of the entitlement theory that undergirds Nozick’s and Mack’s work. Once the theory is properly understood, Barnes’s challenges fail to undermine the Chamberlain example, in particular, and the entitlement theory, in general. (shrink)

In his insightful and challenging paper, Jonathan Schaffer argues against a distinction I make in The Ant Trap (Epstein 2015) and related articles. I argue that in addition to the widely discussed “grounding” relation, there is a different kind of metaphysical determination I name “anchoring.” Grounding and anchoring are distinct, and both need to be a part of full explanations of how facts are metaphysically determined. Schaffer argues instead that anchoring is a species of grounding. The crux of his (...) argument comes in the last sections of his paper, in his discussion of “exportation,” the relations strategy, and the definitions strategy. I am inclined to agree that Schaffer’s interesting strategies offer the best choices for the philosopher who wants to insist that anchoring is a species of grounding. But both, I will argue, are fatally flawed. I do not take the separation of anchors from grounds lightly, but find the evidence in its favor overwhelming. And once the distinction is made, I find anchoring to be a powerful practical tool in metaphysics. Philosophy and Phenomenological Research, Volume 99, Issue 3, Page 768-781, November 2019. (shrink)

We live in a world of crowds and corporations, artworks and artifacts, legislatures and languages, money and markets. These are all social objects — they are made, at least in part, by people and by communities. But what exactly are these things? How are they made, and what is the role of people in making them? In The Ant Trap, Brian Epstein rewrites our understanding of the nature of the social world and the foundations of the social sciences. (...) class='Hi'>Epstein explains and challenges the three prevailing traditions about how the social world is made. One tradition takes the social world to be built out of people, much as traffic is built out of cars. A second tradition also takes people to be the building blocks of the social world, but focuses on thoughts and attitudes we have toward one another. And a third tradition takes the social world to be a collective projection onto the physical world. Epstein shows that these share critical flaws. Most fundamentally, all three traditions overestimate the role of people in building the social world: they are overly anthropocentric. Epstein starts from scratch, bringing the resources of contemporary metaphysics to bear. In the place of traditional theories, he introduces a model based on a new distinction between the grounds and the anchors of social facts. Epstein illustrates the model with a study of the nature of law, and shows how to interpret the prevailing traditions about the social world. Then he turns to social groups, and to what it means for a group to take an action or have an intention. Contrary to the overwhelming consensus, these often depend on more than the actions and intentions of group members. (shrink)

This paper presents a systematic approach for analyzing and explaining the nature of social groups. I argue against prominent views that attempt to unify all social groups or to divide them into simple typologies. Instead I argue that social groups are enormously diverse, but show how we can investigate their natures nonetheless. I analyze social groups from a bottom-up perspective, constructing profiles of the metaphysical features of groups of specific kinds. We can characterize any given kind of social group with (...) four complementary profiles: its “construction” profile, its “extra essentials” profile, its “anchor” profile, and its “accident” profile. Together these provide a framework for understanding the nature of groups, help classify and categorize groups, and shed light on group agency. (shrink)

According to the Fine-Tuning Argument, the existence of life in our universe confirms the Multiverse Hypothesis. A standard objection to FTA is that it violates the Requirement of Total Evidence. I argue that RTE should be rejected in favor of the Predesignation Requirement, according to which, in assessing the outcome of a probabilistic process, we should only use evidence characterizable in a manner available before observing the outcome. This produces the right verdicts in some simple cases in which RTE leads (...) us astray, and, when applied to FTA, it shows that our evidence does confirm HM. (shrink)

A recurring theme dominates recent philosophical debates about the nature of conscious perception: naïve realism’s opponents claim that the view is directly contradicted by empirical science. I argue that, despite their current popularity, empirical arguments against naïve realism are fundamentally flawed. The non-empirical premises needed to get from empirical scientific findings to substantive philosophical conclusions are ones the naïve realist is known to reject. Even granting the contentious premises, the empirical findings do not undermine the theory, given its overall philosophical (...) commitments. Thus, contemporary empirical research fails to supply any new argumentative force against naïve realism. I conclude that, as philosophers of mind, we would be better served spending a bit less time trying to wield empirical science as a cudgel against our opponents, and a bit more time working through the implications of each other’s views – something we can accomplish perfectly well from the comfort of our armchairs.

With few exceptions, theorists analyze group attitudes in terms of the attitudes of members. In Epstein 2015, 2019a, 2019b, I argued that this thesis (which I call "MEMBERS ONLY")—and hence any theory that analyzes group attitudes in terms of member attitudes—is mistaken: the attitudes of many groups are ontologically determined by a broader range of factors than member attitudes. My aim in the present paper is to consider new arguments against MEMBERS ONLY. I argue that arguments based on the (...) "hypothesis of the extended mind" are not persuasive for challenging MEMBERS ONLY, but reinforce my earlier arguments, and I also propose new arguments from group content externalism are more promising.

The Gestalt psychologists adopted a set of positions on mind-body issues that seem like an odd mix. They sought to combine a version of naturalism and physiological reductionism with an insistence on the reality of the phenomenal and the attribution of meanings to objects as natural characteristics. After reviewing basic positions in contemporary philosophy of mind, we examine the Gestalt position, characterizing it m terms of phenomenal realism and programmatic reductionism. We then distinguish Gestalt philosophy of mind from instrumentalism and (...) computational functionalism, and examine Gestalt attributions of meaning and value to perceived objects. Finally, we consider a metatheoretical moral from Gestalt theory, which commends the search for commensurate description of mental phenomena and their physiological counterparts. (shrink)

The thesis of methodological individualism in social science is commonly divided into two different claims—explanatory individualism and ontological individualism. Ontological individualism is the thesis that facts about individuals exhaustively determine social facts. Initially taken to be a claim about the identity of groups with sets of individuals or their properties, ontological individualism has more recently been understood as a global supervenience claim. While explanatory individualism has remained controversial, ontological individualism thus understood is almost universally accepted. In this paper I argue (...) that ontological individualism is false. Only if the thesis is weakened to the point that it is equivalent to physicalism can it be true, but then it fails to be a thesis about the determination of social facts by facts about individual persons. Even when individualistic facts are expanded to include people’s local environments and practices, I shall argue, those still underdetermine the social facts that obtain. If true, this has implications for explanation as well as ontology. I first consider arguments against the local supervenience of social facts on facts about individuals, correcting some flaws in existing arguments and affirming that local supervenience fails for a broad set of social properties. I subsequently apply a similar approach to defeat a particularly weak form of global supervenience, and consider potential responses. Finally, I explore why it is that people have taken ontological individualism to be true. (shrink)

The problem of divine impassibility, i.e., of whether the divine nature in Christ could suffer, stands at the center of a debate regarding the nature of God and his relation to us. Whereas philosophical reasoning regarding the divine nature maintains that the divine is immutable and perfect in every respect, theological needs generated an ever-growing demand for a passionate God truly able to participate in the suffering of his creatures. Correlating with the different approaches of Thomas Aquinas and John Duns (...) Scotus, the paper develops an incarnation model that aims, on the one hand, to solve the dualistic problem between the divine and human natures, and on the other hand to make room for both impassible and passible elements in God, and so to make room within the patristic impassible model for genuine suffering in God. The discussion, though centered around Christ's im/passibility and passions, can easily be modified to approach the body-mind problem since the essence of the problems is the same. (shrink)

In recent years, theorists have debated how we introduce new social objects and kinds into the world. Searle, for instance, proposes that they are introduced by collective acceptance of a constitutive rule; Millikan and Elder that they are the products of reproduction processes; Thomasson that they result from creator intentions and subsequent intentional reproduction; and so on. In this chapter, I argue against the idea that there is a single generic method or set of requirements for doing so. Instead, there (...) is a variety of what I call “anchoring schemas,” or methods by which new social kinds are generated. Not only are social kinds a diverse lot, but the metaphysical explanation for their being the kinds they are is diverse as well. I explain the idea of anchoring and present examples of social kinds that are similar to one another but that are anchored in different ways. I also respond to Millikan’s argument that there is only one kind of “glue” that is “sticky enough” for holding together kinds. I argue that no anchoring schema will work in all environments. It is a contingent matter which schemas are successful for anchoring new social kinds, and an anchoring schema need only be “sticky enough” for practical purposes in a given environment. (shrink)

Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory for groups (...) (n = 74). Assessments were performed at pre-, post-, and 6-month follow-up phases. Results. Meditation awareness training participants demonstrated significant and sustained improvements over control group participants in FMS symptomatology, pain perception, sleep quality, psychological distress, non-attachment (to self, symptoms, and environment), and civic engagement. A mediation analysis found that (1) civic engagement partially mediated treatment effects for all outcome variables, (2) non-attachment partially mediated treatment effects for psychological distress and sleep quality, and (3) non-attachment almost fully mediated treatment effects for FMS symptomatology and pain perception. Average daily time spent in meditation was found to be a significant predictor of changes in all outcome variables. Conclusions. Meditation awareness training may be a suitable treatment for adults with FMS and appears to ameliorate FMS symptomatology and pain perception by reducing attachment to self. (shrink)

A piece of folklore enjoys some currency among philosophical Bayesians, according to which Bayesian agents that, intuitively speaking, spread their credence over the entire space of available hypotheses are certain to converge to the truth. The goals of the present discussion are to show that kernel of truth in this folklore is in some ways fairly small and to argue that Bayesian convergence-to-the-truth results are a liability for Bayesianism as an account of rationality, since they render a certain sort of (...) arrogance rationally mandatory.

It is often seen as a truism that social objects and facts are the product of human intentions. I argue that the role of intentions in social ontology is commonly overestimated. I introduce a distinction that is implicit in much discussion of social ontology, but is often overlooked: between a social entity’s “grounds” and its “anchors.” For both, I argue that intentions, either individual or collective, are less essential than many theorists have assumed. Instead, I propose a more worldly – (...) and less intellectualist – approach to social ontology. (shrink)

The paper by Monteiro, Musten and Compson (2014) is to be commended for providing a comprehensive discussion of the compatibility issues arising from the integration of mindfulness – a 2,500-year-old Buddhist practice – into research and applied psychological domains. Consistent with the observations of various others (e.g., Dunne, 2011; Kang & Whittingham, 2010), Monteiro and colleagues have not only highlighted that there are differences in how Buddhism and contemporary mindfulness interventional approaches interpret and contextualize mindfulness, but there are also differing (...) interpretations of mindfulness within Buddhism. These apparent differences within Buddhism are arguably more noticeable when making comparisons across Buddhist vehicles (i.e., Theravada, Mahayana, Vajrayana), but to a lesser extent intra-vehicular differences can also be said to exist (i.e., differences between Buddhist traditions of the same vehicle). This commentary investigates the validity of some of these different Buddhist constructions of mindfulness, and then discusses how a better understanding of their scriptural and conceptual soundness (or lack thereof) may help to reconcile some of the actual and perceived incompatibility between Buddhist practice and contemporary secular mindfulness-based approaches.

Individualists about social ontology hold that social facts are “built out of” facts about individuals. In this paper, I argue that there are two distinct kinds of individualism about social ontology, two different ways individual people might be the metaphysical “builders” of the social world. The familiar kind is ontological individualism. This is the thesis that social facts supervene on, or are exhaustively grounded by, facts about individual people. What I call anchor individualism is the alternative thesis that facts about (...) individuals put in place the conditions for a social entity to exist, or the conditions for something to have a social property. Examples include conventionalist theories of the social world, such as David Hume’s theories of promises, money, and government, and collective acceptance theories, such as John Searle’s theory of institutional facts. Anchor individualism is often conflated with ontological individualism. But in fact, the two theses are in tension with one another: if one of these kinds of individualism is true, then the other is very unlikely to be. My aim in this paper is to clarify both, and argue that they should be sharply distinguished from one another. (shrink)

Agent-​​based modeling is showing great promise in the social sciences. However, two misconceptions about the relation between social macroproperties and microproperties afflict agent-based models. These lead current models to systematically ignore factors relevant to the properties they intend to model, and to overlook a wide range of model designs. Correcting for these brings painful trade-​​offs, but has the potential to transform the utility of such models.

In this paper we show how a realistic normative democratic theory can work within the constraints set by the most pessimistic empirical results about voting behaviour and elite capture of the policy process. After setting out the empirical evidence and discussing some extant responses by political theorists, we argue that the evidence produces a two-pronged challenge for democracy: an epistemic challenge concerning the quality and focus of decision-making and an oligarchic challenge concerning power concentration. To address the challenges we then (...) put forward three main normative claims, each of which is compatible with the evidence. We start with a critique of the epistocratic position commonly thought to be supported by the evidence. We then introduce a qualified critique of referenda and other forms of plebiscite, and an outline of a tribune-based system of popular control over oligarchic influence on the policy process. Our discussion points towards a renewal of democracy in a plebeian but not plebiscitarian direction: Attention to the relative power of social classes matters more than formal dispersal of power through voting. We close with some methodological reflections about the compatibility between our normative claims and the realist program in political philosophy. (shrink)

This essay revisits some classic problems in the philosophy of space and time concerning the counting of possibilities. I argue that we should think that two Newtonian worlds can differ only as to when or where things happen and that general relativistic worlds can differ in something like the same way—the first of these theses being quaintly heterodox, the second baldly heretical, according to the mores of contemporary philosophy of physics.

My aim in this paper is to discuss a metaphysical framework within which to understand “standard linguistic entities” (SLEs), such as words, sentences, phonemes, and other entities routinely employed in linguistic theory. In doing so, I aim to defuse certain kinds of skepticism, challenge convention-based accounts of SLEs, and present a series of distinctions for better understanding what the various accounts of SLEs do and do not accomplish.

I examine issues in the philosophy of religion at the intersection of what possibilities there are and what a God, as classically conceived in the theistic philosophical tradition, would be able to do. The discussion is centered around arguing for an incompatibility between theism and two principles about possibility and ability, and exploring what theists should say about these incompatibilities. -/- I argue that theism entails that certain kinds and amounts of evil are impossible. This puts theism in conflict with (...) popular principles of modal recombination. However, theists have plausible explanations for the violations of recombination that they posit, and can suitably amend these principles without giving up their usefulness in accounting for what possibilities there are. -/- I also argue that despite the impossibility of these evils, God is able to bring these evils about. This puts theism in conflict with the principle that no one is able to do the impossible. However, theists can give a plausible account of why God is unique in being able to do the impossible, and have distinctive resources to address the arguments in favor of the idea that no one is able to do the impossible. And by denying this principle, theists are able to resolve several otherwise difficult puzzles, including reconciling conflicts between the divine attributes. (shrink)

I argue for the viability of one neglected way of developing supervenience-based objections to metaethical non-naturalism. This way goes through a principle known as ‘Hume’s Dictum’, according to which there are no necessary connections between distinct existences.

In the course of doing so, I formulate and motivate modest and precise versions of Hume’s Dictum, illustrate how arguments employing these principles might proceed, and argue that the Hume’s Dictum argument enjoys some advantages (...) relative to other supervenience-based objections to non-naturalism.

Many theorists, including Nietzsche, Adorno, and Foucault, have regarded genealogy as an important technique for social criticism. But it has been unclear how genealogy can go beyond the accomplishments of other, more mundane, critical methods. I propose a new approach to understanding the critical potential of history. I argue that theorists have been misled by the assumption that if a claim is deserving of criticism, it is because the claim is false. Turning to the criticism of concepts rather than criticism (...) of claims, I expand on the distinction between "descriptive semantics" and "foundational semantics" to show that genealogy can be uniquely qualified to explore the foundations of concepts, and hence to criticize concepts that are problematic in nonobvious ways.

In recent years, the project of providing microeconomic foundations for macroeconomics has taken on new urgency. Some philosophers and economists have challenged the project, both for the way economists actually approach microfoundations and for more general anti-reductionist reasons. Reductionists and anti-reductionists alike, however, have taken it to be trivial that the macroeconomic facts are exhaustively determined by microeconomic ones. In this paper, I challenge this supposed triviality. I argue that macroeconomic properties do not even globally supervene on microeconomic ones. This (...) is simply a consequence of the difference in the explanatory goals of the respective fields, which implicitly carve out the microeconomic property set in such a way that it underdetermines macroeconomic properties. It means, however, that microeconomics-based foundations for macroeconomics are inadequate in principle. (shrink)

Sometimes one can prevent harm only by contravening rights. If the harm one can prevent is great enough, compared to the stringency of the opposing rights, then one has a lesser-evil justification to contravene the rights. Non-consequentialist orthodoxy holds that, most of the time, lesser-evil justifications add to agents’ permissible options without taking any away. Helen Frowe rejects this view. She claims that, almost always, agents must act on their lesser-evil justifications. Our primary task is to refute Frowe’s flagship argument. (...) Secondarily, it is to sketch a positive case for nonconsequentialist orthodoxy. (shrink)

I argue that the human mind includes an innate domain-specific system for representing precise small numerical quantities. This theory contrasts with object-tracking theories and with domain-general theories that only make use of mental models. I argue that there is a good amount of evidence for innate representations of small numerical quantities and that such a domain-specific system has explanatory advantages when infants’ poor working memory is taken into account. I also show that the mental models approach requires previously unnoticed domain-specific (...) structure and consequently that there is no domain-general alternative to an innate domain-specific small number system.

Under so-called primitive ontology approaches, in fully describing the history of a quantum system, one thereby attributes interesting properties to regions of spacetime. Primitive ontology approaches, which include some varieties of Bohmian mechanics and spontaneous collapse theories, are interesting in part because they hold out the hope that it should not be too difficult to make a connection between models of quantum mechanics and descriptions of histories of ordinary macroscopic bodies. But such approaches are dualistic, positing a quantum state as (...) well as ordinary material degrees of freedom. This paper lays out and compares some options that primitive ontologists have for making sense of the quantum state. (shrink)

The overwhelming majority of those who theorize about implicit biases posit that these biases are caused by some sort of association. However, what exactly this claim amounts to is rarely specified. In this paper, I distinguish between different understandings of association, and I argue that the crucial senses of association for elucidating implicit bias are the cognitive structure and mental process senses. A hypothesis is subsequently derived: if associations really underpin implicit biases, then implicit biases should be modulated by counterconditioning (...) or extinction but should not be modulated by rational argumentation or logical interventions. This hypothesis is false; implicit biases are not predicated on any associative structures or associative processes but instead arise because of unconscious propositionally structured beliefs. I conclude by discussing how the case study of implicit bias illuminates problems with popular dual-process models of cognitive architecture. (shrink)

It is widely thought that chance should be understood in reductionist terms: claims about chance should be understood as claims that certain patterns of events are instantiated. There are many possible reductionist theories of chance, differing as to which possible pattern of events they take to be chance-making. It is also widely taken to be a norm of rationality that credence should defer to chance: special cases aside, rationality requires that one’s credence function, when conditionalized on the chance-making facts, should (...) coincide with the objective chance function. It is a shortcoming of a theory of chance if it implies that this norm of rationality is unsatisfiable. The primary goal of this paper is to show, on the basis of considerations concerning computability and inductive learning, that this shortcoming is more common than one would have hoped. (shrink)

Debates about modularity invariably involve a crucial premise about how visual illusions are experienced. This paper argues that these debates are wrongheaded, and that experience of illusions is orthogonal to the core issue of the modularity hypothesis: informational encapsulation.

I argue that classical theism is in tension with a kind of modal recombination principle known as ‘cut-and-paste’. I develop this tension at length, giving two arguments against theism based on cut-and-paste. I then both lay out and respond to various original proposals for reconciling theism with cut-and-paste. I conclude by measuring the cost of having to deny cut-and-paste. I argue that while there is an intuitive cost to this consequence of theism, theists also have plausible ways of addressing various (...) motivations for cut-and-paste. (shrink)

Models treating the simple properties of social groups have a common shortcoming. Typically, they focus on the local properties of group members and the features of the world with which group members interact.

Adequate models and social policies must treat certain (...) factors that are not local to individual members of the group, even if those factors are not causally connected to those individuals.

This paper is concerned with the relation between two notions: that of two solutions or models of a theory being related by a symmetry of the theory and that of solutions or models being physically equivalent. A number of authors have recently discussed this relation, some taking an optimistic view, on which there is a suitable concept of the symmetry of a theory relative to which these two notions coincide, others taking a pessimistic view, on which there is no such (...) concept. The present paper arrives at a cautiously pessimistic conclusion. (shrink)

Unconscious logical inference seems to rely on the syntactic structures of mental representations (Quilty-Dunn & Mandelbaum 2018). Other transitions, such as transitions using iconic representations and associative transitions, are harder to assimilate to syntax-based theories. Here we tackle these difficulties head on in the interest of a fuller taxonomy of mental transitions. Along the way we discuss how icons can be compositional without having constituent structure, and expand and defend the “symmetry condition” on Associationism (the idea that associative links and (...) transitions are perfectly symmetric). In the end, we show how a BIT (“bare inferential transition”) theory can cohabitate with these other non-inferential mental transitions. (shrink)

Following an Open conception of Divine Foreknowledge, that holds that man is endowed with genuine freedom and so the future is not definitely determined, it will be claimed that human freedom does not limit the divine power, but rather enhances it and presents us with a barrier against arbitrary use of that power.

What are the conditions for fixing the reference of a proper name? Debate on this point has recently been rekindled by Scott Soames, Robin Jeshion, and others. In this paper, I sketch a new pragmatic approach to the justification of reference-fixing procedures, in opposition to accounts that insist on an invariant set of conditions for fixing reference across environments and linguistic communities. Comparing reference to other relations whose instances are introduced through "initiation" procedures, I outline a picture in which the (...) procedures that are successful for fixing the reference of proper names depend in part on regularities in the actual environment.

In a recent article, Harold Noonan argues that application conditions and criteria of identity are not distinct from one another. This seems to threaten the standard approach to distinguishing sortals from adjectival terms. I propose that his observation, while correct, does not have this consequence.

Martin Heidegger devotes extensive discussion to medieval philosophers, particularly to their treatment of Truth and Being. On both these topics, Heidegger accuses them of forgetting the question of Being and of being responsible for subjugating truth to the modern crusade for certainty: ‘truth is denied its own mode of being’ and is subordinated ‘to an intellect that judges correctly’. Though there are some studies that discuss Heidegger’s debt to and criticism of medieval thought, particularly that of Thomas Aquinas, there is (...) no constructive reply to his assertions. As a result, Heidegger’s critique had an unprecedented effect on the credibility of medieval philosophy, whereby great portions of the philosophical community dismiss it altogether as an illegitimate Onto‐Theology. It is the aim of this study to offer a constructive reply that will fundamentally grapple with these allegations. By constructive reply we mean not only a reply that avoids the problems Heidegger raises regarding existence, essence and truth, but more importantly, one that uses Heidegger’s criticism in order to present a more insightful account of these notions. The present study is composed of two parts where the second serves as a sort of addendum. The first part, the core of this study, is an attempt to develop an understanding of the distinction between essence and existence that, on the one hand, accords with Heidegger’s criticism while on the other hand advances our understanding of how we think and understand reality. After presenting Heidegger’s depiction of Aquinas’s distinction between essence and existence (esse) as a real distinction, the study will present several views propounded by scholars of Aquinas regarding the status of this distinction. It will be argued that it is not clear whether the distinction is real, formal or conceptual, and that different types of distinction are applied in different places, particularly in regard to the phantasm that Aquinas considers essential to the human act of thinking. The second part diverges from the first part and focuses on Heidegger’s criticism of Aquinas’s conception of truth as adequation, i.e., what it is that grounds the possibility of truth as adequation. This divergence is necessary in order to present a full metaphysical response to Heidegger’s criticism. Since the aim of the present study is to argue that Aquinas’s philosophical system can contend with Heidegger’s criticism, a partial reply would greatly diminish its effectiveness. (shrink)

Some learning strategies that work well when computational considerations are abstracted away from become severely limiting when such considerations are taken into account. We illustrate this phenomenon for agents who attempt to extrapolate patterns in binary data streams chosen from among a countable family of possibilities. If computational constraints are ignored, then two strategies that will always work are learning by enumeration (enumerate the possibilities---in order of simplicity, say---then search for the one earliest in the ordering that agrees with your (...) data and use it to predict the next data point) and Bayesian learning. But there are many types of computable data streams that, although they can be successfully extrapolated by computable agents, cannot be handled by any computable learner by enumeration. And while there is a sense in which Bayesian learning is a fully general strategy for computable learners, the ability to mimic powerful learners comes at a price for Bayesians: they cannot, in general, become highly confident of their predictions in the limit of large data sets and they cannot, in general, use priors that incorporate all relevant background knowledge.

Neoplatonism is alive and well today. It expresses itself in New Thought and the mind-cure movements derived from it. However, to avoid many ancient errors, Neoplatonism needs to be modernized. The One is just the simple origin from which all complex things evolve. The Good, which is not the One, is the best of all possible propositions. A cosmological argument is given for the One and an ontological argument for the Good. The presence of the Good in every thing is (...) Spirit. Spirit sits in the logical center of every body; it is surrounded by the regulatory forms of that body. Striving for the Good, Spirit seeks to correct the errors in its surrounding forms. To correct the errors in biological texts, modern Neoplatonists turn to the experimental method. This Neoplatonism is pantheistic not because of some theoretical definition of God but rather because of its practical focus on the shaping of Spirit. (shrink)

After presenting evidence about categorization behavior, this paper argues for the following theses: 1) that there is a border between perception and cognition; 2) that the border is to be characterized by perception being modular (and cognition not being so); 3) that perception outputs conceptualized representations, so views that posit that the output of perception is solely non-conceptual are false; and 4) that perceptual content consists of basic-level categories and not richer contents.

“What is the structure of thought?” is as central a question as any in cognitive science. A classic answer to this question has appealed to a Language of Thought (LoT). We point to emerging research from disparate branches of the field that supports the LoT hypothesis, but also uncovers diversity in LoTs across cognitive systems, stages of development, and species. Our letter formulates open research questions for cognitive science concerning the varieties of rules and representations that underwrite various LoT-based systems (...) and how these variations can help researchers taxonomize cognitive systems.

This paper is concerned with learners who aim to learn patterns in infinite binary sequences: shown longer and longer initial segments of a binary sequence, they either attempt to predict whether the next bit will be a 0 or will be a 1 or they issue forecast probabilities for these events. Several variants of this problem are considered. In each case, a no-free-lunch result of the following form is established: the problem of learning is a formidably difficult one, in that (...) no matter what method is pursued, failure is incomparably more common that success; and difficult choices must be faced in choosing a method of learning, since no approach dominates all others in its range of success. In the simplest case, the comparison of the set of situations in which a method fails and the set of situations in which it succeeds is a matter of cardinality (countable vs. uncountable); in other cases, it is a topological matter (meagre vs. co-meagre) or a hybrid computational-topological matter (effectively meagre vs. effectively co-meagre).

Do university ethics classes influence students’ real-world moral choices? We aimed to conduct the first controlled study of the effects of ordinary philosophical ethics classes on real-world moral choices, using non-self-report, non-laboratory behavior as the dependent measure. We assigned 1332 students in four large philosophy classes to either an experimental group on the ethics of eating meat or a control group on the ethics of charitable giving. Students in each group read a philosophy article on their assigned topic and optionally (...) viewed a related video, then met with teaching assistants for 50-minute group discussion sections. They expressed their opinions about meat ethics and charitable giving in a follow-up questionnaire (1032 respondents after exclusions). We obtained 13,642 food purchase receipts from campus restaurants for 495 of the students, before and after the intervention. Purchase of meat products declined in the experimental group (52% of purchases of at least $4.99 contained meat before the intervention, compared to 45% after) but remained the same in the control group (52% both before and after). Ethical opinion also differed, with 43% of students in the experimental group agreeing that eating the meat of factory farmed animals is unethical compared to 29% in the control group. We also attempted to measure food choice using vouchers, but voucher redemption rates were low and no effect was statistically detectable. It remains unclear what aspect of instruction influenced behavior. (shrink)

In general, Confucians have taken a dim view of the law. They have felt warranted in this view by a reading of Confucius’ Analects 2.3 in which the Master apparently disparages law-centered governance. Two great Confucian philosophers, however, Zhu Xi and Jeong Yakyong (widely known by his pen name, Dasan), view the role of law in society differently. Like all Confucians, they teach the cultivation of virtue, but alongside building social harmony through ritual and good character, these two philosophers perceive (...) that social order also requires the penal law. In this paper, I argue that Zhu Xi and Dasan, and Dasan in particular, follow the evidentiary lead of the classical Chinese philosopher Mozi to support their legal philosophy. Mozi offered three standards for establishing truth claims: empirical evidence from common life, authoritative evidence, and evidence of outcomes. Mozi’s empirical standard takes evidence of common life from what ordinary people have seen. Zhu Xi and Dasan take the evidence of common life, not from what the people have seen, but from common understandings contained in the written language. They use this approach to arrive at a different understanding of Analects 2.3 than other Confucians, one that relates the content of that passage to Analects 12.17. They interpret the passage on a philological basis that supports the presence of penal law from a perspective of ordinary life. For authoritative evidence, Zhu Xi and Dasan like Mozi appeal to the authority of the ancient sages, who register their support for penal law. Dasan also follows Mozi’s evidentiary lead in the evidence of outcomes by fully developing a consequential picture of how the absence of law detrimentally affects society. On this point, Dasan establishes a new and revolutionary legal outlook that differs from that of Zhu Xi. I show Dasan taking lessons from the classical Legalists to arrive at this position warranted by the evidence of outcomes. Having satisfied the three evidentiary standards, Dasan thus establishes the importance of the penal law from a Confucian perspective. (shrink)

The philosopher of chemistry Andrea Woody has recently published a wide-ranging article concerning the turn to practice in the philosophy of science. Her primary example consists of the use of different forms of representations by Lothar Meyer and Mendeleev when they presented their views on chemical periodicity. Woody believes that this distinction can cast light on various issues including why Mendeleev was able to make predictions while Meyer was not. Secondly, she claims that it can clarify the much-debated question concerning (...) the relative values of prediction and accommodation of data in the way that the periodic system was accepted. Thirdly, Woody believes that such differences in the representation of periodicity can be used to argue for the explanatory nature of the periodic table in contrast with the more traditional view that the periodic table is not explanatory.
