The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

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)

Together with the return to traditional religions and the parallel immersion in pagan and Orthodox archaism, a third tendency—minimal religion, or "poor faith"—can be observed in contemporary Russia. According to the polls, more than one fourth of Russians believe in God but are not affiliated with any specific religion or denomination. To date, this type of religiosity has attracted the least attention because it has no clear organizational and dogmatic manifestations and tends to escape all forms of objectification. Its ‘minimality’ (...) almost precludes the formation of dogma or ritual and can be identified only as an internal impulse, a state of spirit, or a disposition of mind. This is what is called ‘poor’ or ‘minimal’ religion. For a Western observer, a more ‘recognizable’ name for it would be religious modernism, universalism, or ecumenicism, even if these terms do not exactly correspond to the Russian phenomenon. The spiritual vacuum, created by Soviet atheism, gave rise in the 1970s — 1990s to this new type of religiosity. Minimal religion is transcendental in two senses. As a religion, in distinction from a purely secular position, it transcends the ‘earthly’ world of immanence. As a minimal religion, in distinction from all organized religions, it transcends the world of all existing religious traditions, dogmas, rituals, and affiliations. It is only in the liminal ‘between’ that this uniquely postsecular phenomenon can be defined. Religion, yet minimal; poor, yet faith. (shrink)

This essay in the form of theses presents a new, post–secular type of religiosity that emerged in Russia in the aftermath of the collapse of Soviet dogmatic atheism. Poor faith is faith without any temples, dogma or rites, as integrally standing before God as God Himself is integral and undivided. According to the results of the largest sociological survey in Russia almost 60,000 respondents in 2012, one in four people fall into the category of ‘poor religion’— a simple belief in (...) God without any affiliation to a belief system or denomination. This proportion, 25 %, comes second only to Orthodox Christian believers (41 %) and exceeds Muslims (6.5 %). The poor faith manifested itself as an indivisible sense of God, outside historical, national and confessional traditions. Thus minimal religion became the next stage of apophaticism after it had crossed the line of atheism and reclaimed its religious content. Paradoxically, this "faith as such," "faith in general" was prepared by the atheist denial of all faiths, of all positive distinctions among historical religions. In 95 theses, this essay introduces major aspects of this new a–theology in comparison with Protestantism and other trans–religious teaching: the ethics and theology of singularity, creativity and resurrection; interaction with science and the views on theodicy; the dynamics and stages of poor faith; its similarity and distinction from spirituality; its place among post–secular trends, including "poor messianism." -/- "faith as such," "faith in general" was prepared by the atheist denial of all faiths.

This article seeks the origin, in the theories of Ibn al-Haytham (Alhazen), Descartes, and Berkeley, of two-stage theories of spatial perception, which hold that visual perception involves both an immediate representation of the proximal stimulus in a two-dimensional ‘‘sensory core’’ and also a subsequent perception of the three dimensional world. The works of Ibn al-Haytham, Descartes, and Berkeley already frame the major theoretical options that guided visual theory into the twentieth century. The field of visual perception was the first area (...) of what we now call psychology to apply mathematics, through geometrical models as used by Euclid, Ptolemy, Ibn al-Haytham, and Descartes (among others). The article shows that Kepler’s discovery of the retinal image, which revolutionized visual anatomy and entailed fundamental changes in visual physiology, did not alter the basic structure of theories of spatial vision. These changes in visual physiology are advanced especially in Descartes' Dioptrics and his L'Homme. Berkeley develops a radically empirist theory vision, according to which visual perception of depth is learned through associative processes that rely on the sense of touch. But Descartes and Berkeley share the assertion that there is a two-dimensional sensory core that is in principle available to consciousness. They also share the observation that we don't usually perceived this core, but find depth and distance to be phenomenally immediate, a point they struggle to accommodate theoretically. If our interpretation is correct, it was not a change in the theory of the psychology of vision that engendered the idea of a sensory core, but rather the introduction of the theory into a new metaphysical context.

Shepard has supposed that the mind is stocked with innate knowledge of the world and that this knowledge figures prominently in the way we see the world. According to him, this internal knowledge is the legacy of a process of internalization; a process of natural selection over the evolutionary history of the species. Shepard has developed his proposal most fully in his analysis of the relation between kinematic geometry and the shape of the motion path in apparent motion displays. We (...) argue that Shepard has made a case for applying the principles of kinematic geometry to the perception of motion, but that he has not made the case for injecting these principles into the mind of the percipient. We offer a more modest interpretation of his important findings: that kinematic geometry may be a model of apparent motion. Inasmuch as our recommended interpretation does not lodge geometry in the mind of the percipient, the motivation of positing internalization, a process that moves kinematic geometry into the mind, is obviated. In our conclusion, we suggest that cognitive psychologists, in their embrace of internal mental universals and internalization may have been seduced by the siren call of metaphor. Key Words: apparent motion; imagery; internalization; inverse projection problem; kinematic geometry; measurement; metaphors of mind. (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)

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)

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)

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.

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)

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)

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 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)

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)

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.

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.

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.

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)

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.

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)

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. I consider economic models of bureaucratic corruption, to show that (a) simple properties of groups are often constituted by the properties of the wider population, and (b) even sophisticated models are commonly inadequate to account for many simple social properties. 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. Key Words: individualism • corruption • supervenience • model • cause. (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.

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. I present a simple scheme for distinguishing sortals from adjectival terms. I also propose an amended version of the standard canonical form of criteria of identity.

Are the standards of reasoning and rationality in divination, religious practice, and textual exegesis different from those in the sciences? Can there be different standards of reasoning and rationality at all? The intense “rationality debate” of the 1960s, 70s, and 80s focused on these questions and the related problems of relativism across cultures and systems of practice. Although philosophers were at the center of these debates at the time, they may appear to have abandoned the question in recent years. On (...) the contrary, I discuss recent developments in philosophy that approach the issue from a number of new directions, changing our understanding of reasoning and rationality. I argue that, in comparing the diviner to the scientist, focusing on reasoning is likely to be a red herring. Instead, I argue that a careful treatment of rationality, paying particular attention to its context-dependence, untangles longstanding confusions. Moreover, it points the way forward to investigating modest but interesting ways for there to be alternative standards of rationality. (shrink)

Chomsky and others have denied the relevance of external linguistic entities, such as E-languages, to linguistic explanation, and have questioned their coherence altogether. I discuss a new approach to understanding the nature of linguistic entities, focusing in particular on making sense of the varieties of kinds of “words” that are employed in linguistic theorizing. This treatment of linguistic entities in general is applied to constructing an understanding of external linguistic entities.

The article aims to substantiate the philosophy of synthesis, which is built on the basis of analysis, but gives it a constructive direction. The turning point from analysis to synthesis is the problematization of the elements identified in the analysis, their criticism, replacement, or rearrangement, leading to the construction of alternative concepts and propositions that expand the field of the thinkable and innovate the categorical apparatus of philosophy. This article provides examples of philosophical synthesis at different levels: alternative terms and (...) concepts (“infinition”), postulates (the “diamond rule” in ethics), and disciplines (“horrology” as the study of the self-destructive mechanisms of civilization). Next, we consider the transition from the philosophy of synthesis to the synthesis of philosophy itself with contemporary scientific and technical practices. Technology of the 21st century is no longer instrumental/utilitarian, but a fundamental technology ("onto–technology"), which, thanks to science’s penetration into the micro- and macrocosm, can change the foundational parameters of being, thereby acquiring a philosophical dimension. Accordingly, philosophy as a study of the most general principles of the universe becomes a practical requirement in any “world-forming,” synthesizing acts of technology, including the design of computer games and multi-populated virtual worlds (e.g., “Second Life”), that involve a new ontology, logic, ethics, and axiology. The vocation of philosophy in the 21st century is not just to comprehend our unique world, but to lay the foundations for new world-forming practices, to initiate and design the ontology of possible worlds, and to pave the way for alternative forms of synthetic life and artificial intelligence. Contrary to Hegel, philosophy is no longer the “owl of Minerva” taking flight at dusk, but a skylark proclaiming the dawn of a new creative day. -/- . (shrink)

This fascinating collection on artifacts brings together seven papers by philosophers with nine by psychologists, biologists, and an archaeologist. The psychological papers include two excellent discussions of empirical work on the mental representation of artifact concepts – an assessment by Malt and Sloman of a large variety of studies on the conflicting ways we classify artifacts and extend our applications of artifact categories to new cases, and a review by Mahon and Caramazza of data from semantically impaired patients and from (...) neuroimaging on concepts of living kinds versus artifact kinds. Following these are three papers on the development of artifact concepts in children, including a short but provocative piece by Keil, Greif, and Kerner arguing that there is a mismatch between the patterns of development for our concepts of artifacts and the patterns of representation we end up developing. The final part of the book includes authoritative papers on artifact use by insects, birds, and mammals, by primates, and by Australopithecines and Neanderthals. (shrink)

The turn to analytic philosophy in Anglophone countries, which is still underway and is spreading elsewhere, has generally involved a retreat from ‘synoptic’ thinking and an almost complete withdrawal from ‘synthetic’ thinking, the creative thinking that in the past has been the source of the greatest contributions of philosophy to science, the humanities and civilization. Analytic philosophy’s ‘naturalistic turn’ led by Willard van Ormond Quine was really a capitulation of philosophy to mainstream reductionist science. So-called ‘continental philosophy’ when it abjures (...) naturalism, offers no real challenge to this. This paper attempts to recover a much more powerful challenge to such analytic philosophy and reductionist science, a philosophy which is naturalist but values synopsis and synthesis along with analysis: speculative naturalism. As such, this is presented as a manifesto not only for philosophy, but for science and the humanities. As Mikhail Epstein argued, the practical outcome of the humanities is the transformation of culture. To transform culture is to transform ourselves, our society and our relationship to each other and to nature. (shrink)

Epstein and Carnielli's fine textbook on logic and computability is now in its second edition.

This paper discusses three relevant logics that obey Component Homogeneity - a principle that Goddard and Routley introduce in their project of a logic of significance. The paper establishes two main results. First, it establishes a general characterization result for two families of logic that obey Component Homogeneity - that is, we provide a set of necessary and sufficient conditions for their consequence relations. From this, we derive characterization results for S*fde, dS*fde, crossS*fde. Second, the paper establishes complete sequent calculi (...) for S*fde, dS*fde, crossS*fde. Among the other accomplishments of the paper, we generalize the semantics from Bochvar, Hallden, Deutsch and Daniels, we provide a general recipe to define containment logics, we explore the single-premise/single-conclusion fragment of S*fde, dS*fde, crossS*fdeand the connections between crossS*fde and the logic Eq of equality by Epstein. Also, we present S*fde as a relevant logic of meaninglessness that follows the main philosophical tenets of Goddard and Routley, and we briefly examine three further systems that are closely related to our main logics. Finally, we discuss Routley's criticism to containment logic in light of our results, and overview some open issues. (shrink)

The paper indicates how social kinds may be internally and objectively unified in a way continuous with physical kinds. It argues that the practice of theorizing is continuous with other practices to the extent that theorists, like anyone engaged in a practice, needs to make choices that are responsive to purposes (and corresponding values) guiding the practice. The paper discusses Epstein's theory of anchoring, and argues for a theory of scaffolding social kinds.

In this thesis, I give a metascientific account of causality in medicine. I begin with two historical cases of causal discovery. These are the discovery of the causation of Burkitt’s lymphoma by the Epstein-Barr virus, and of the various viral causes suggested for cervical cancer. These historical cases then support a philosophical discussion of causality in medicine. This begins with an introduction to the Russo- Williamson thesis (RWT), and discussion of a range of counter-arguments against it. Despite these, I (...) argue that the RWT is historically workable, given a small number of modifications. I then expand Russo and Williamson’s account. I first develop their suggestion that causal relationships in medicine require some kind of evidence of mechanism. I begin with a number of accounts of mechanisms and produce a range of consensus features of them. I then develop this consensus position by reference to the two historical case studies with an eye to their operational competence. In particular, I suggest that it is mechanistic models and their representations which we are concerned with in medicine, rather than the mechanism as it exists in the world. -/- I then employ these mechanistic models to give an account of the sorts of evidence used in formulating and evaluating causal claims. Again, I use the two human viral oncogenesis cases to give this account. I characterise and distinguish evidence of mechanism from evidence of difference-making, and relate this to mechanistic models. I then suggest the relationship between types of evidence presents us with a means of tackling the reference-class problem. This sets the scene for the final chapter. Here, I suggest the manner in which these two different classes of evidence become integrated is also reflected in the way that developing research programmes change as their associated causal claims develop.

This paper tries to answer the question why the epistemic value of so many social simulations is questionable. I consider the epistemic value of a social simulation as questionable if it contributes neither directly nor indirectly to the understanding of empirical reality. To examine this question, two classical social simulations are analyzed with respect to their possible epistemic justification: Schelling’s neighborhood segregation model and Axelrod’s reiterated Prisoner’s Dilemma simulations of the evolution of cooperation. It is argued that Schelling’s simulation is (...) useful because it can be related to empirical reality, while Axelrod’s simulations and those of his followers cannot and thus that their scientific value remains doubtful. I relate this findingto the background beliefs of modelers about the superiority of the modeling method as expressed in Joshua Epstein’s keynote address “Why model?”. (shrink)

Is there a political philosophy of conservatism? A history of the phenomenon written along sceptical lines casts doubt on the existence of a transhistorical doctrine, or even an enduring conservative outlook. The main typologies of conservatism uniformly trace its origins to opposition to the French Revolution. Accordingly, Edmund Burke is standardly singled out as the ‘father’ of this style of politics. Yet Burke was de facto an opposition Whig who devoted his career to assorted programmes of reform. In restoring Burke (...) to his original milieu, the argument presented here takes issue with 20th-century accounts of conservative ideology developed by such figures as Karl Mannheim, Klaus Epstein and Samuel Huntington. It argues that the idea of a conservative tradition is best seen as a belated construction, and that the notion of a univocal philosophy of conservatism is basically misconceived. (shrink)

We examine the set of formula-to-formula valid inferences of Classical Logic, where the premise and the conclusion share at least a propositional variable in common. We review the fact, already proved in the literature, that such a system is identical to the first-degree entailment fragment of R. Epstein's Relatedness Logic, and that it is a non-transitive logic of the sort investigated by S. Frankowski and others. Furthermore, we provide a semantics and a calculus for this logic. The semantics is (...) defined in terms of a \-matrix built on top of a 5-valued extension of the 3-element weak Kleene algebra, whereas the calculus is defined in terms of a Gentzen-style sequent system where the left and right negation rules are subject to linguistic constraints.

C.D. Broad pointed out that philosophy in the Twentieth Century radically reduced its scope by contracting the methods it deployed. While traditionally philosophers had used analysis, synopsis and synthesis to reveal and overcome the inconsistencies of culture, critical philosophers reduced the role accorded to synopsis and eliminated any role for synthesis. This, it is argued, was a disastrous wrong turn that has led philosophers to embrace scientism, equated with naturalism, which has marginalized and reduced to irrelevance not only most of (...) philosophy, but most of the humanities. Showing how such philosophy evolved from one branch of neo-Kantian philosophy, it is argued there was no reason to constrict philosophy in this way. An alternative, more fruitful but largely misrepresented and submerged tradition of philosophical naturalism deriving from Kant is identified, a tradition which can best be characterized as “speculative naturalism”. This tradition, unlike the tradition of analytic philosophy, has made major contributions to science, and is allying science and the humanities. As Michail Epstein pointed out, while the practical outcome of natural science is technology, the practical outcome of the humanities is the transformation of culture, and ourselves. It is central to the creation of the future. Philosophy associated with speculative naturalism promises to play a major role in the transformation of culture required to overcome the current global ecological crisis. It could provide the foundation for a new “ecological civilization”. (shrink)

Before the 2007–2008 global financial crisis, the vast majority of social scientists were not paying much attention to the politics of central banking, despite the fact that, since their creation, central banks have been pivotal institutions between private financial institutions and public authorities (Singleton, 2010). During the past decades, central banks acquired considerable independence from public officials under the Central Bank Independence (CBI) template (McNamara, 2002). Governments justified their decisions to delegate monetary competences by relying on a narrow conception of (...) monetary policy, in which central bankers should only seek to control inflation and ignore the implications of their policies on other economic issues such as financial stability or wealth inequalities (Issing et al., 2001; Marcussen, 2009). Heterodox economists and critical political economists opposed this view by declaring that monetary policy is fundamentally political as it deals with complicated policy trade-offs, which generates winners and losers (Epstein & Gintis, 1995; Forder, 2005). However, until 2007, their concerns were very marginal and remained at the fringes of the political debate. The vast majority of policy-makers, economists, and central bankers themselves agreed on the fact that the CBI template was the optimal institutional arrangement between fiscal and monetary authorities.

This is a Turing Machine which computes the exponential function f(x,y) = xˆy. Instructions format and operation of this machine are intended to best reflect the basic conditions outlined by Alan Turing in his On Computable Numbers, with an Application to the Entscheidungsproblem (1936), using the simplest single-tape and single-symbol version, in essence due to Kleene (1952) and Carnielli & Epstein (2008). This machine is composed by four basic task machines: one which checks if exponent y is zero, a (...) second which checks if base x is zero, a third that is able to copy the base, and a fourth able to multiply multiple factors (in this case, factors will be all equal). They were conveniently separated in order to ease the reader's task to understand each step of its operation. We adopt the convention that a number n is represented by a string of n+1 symbols "1". Thus, an entry (x, y) will be represented by two respective strings of x+1 and y+1 symbols "1", separated by a single "0" (or a blank), and as an output, this machine will generate a string of (xˆy)+1 symbols "1". Some of the instructions are followed by a brief description of what's going on. (shrink)

This essay is a short but impacting observation of the economy of the Middle Ages in light of recent economic historians’ discoveries: not only are some conventional beliefs such as the absence of a financial and trading economy of the period discredited, but a more nuanced view of feudalism also emerges from such revelations. The new, groundbreaking work of Michael McCormick is pitted against Henri Pirenne’s classic theory; in addition, seminal works by Marc Bloch, S.R. Epstein, and lesser known (...) work by Aron Gurevich provide a more authentic view of Middle-Age economy. Finally, contrary to Marxist historiography, this essay postulates that to some extent feudalism fomented the development of capitalism. (shrink)
