This is a three-part exchange on the relationship between belief and credence. It begins with an opening essay by Roger Clarke that argues for the claim that the notion of credence generalizes the notion of belief. Julia Staffel argues in her reply that we need to distinguish between mental states and models representing them, and that this helps us explain what it could mean that belief is a special case of credence. Roger Clarke's final essay reflects (...) on the compatibility of the previously discussed views with dualist and monist interpretations of our mental states and our ways of modeling them. (shrink)

This paper argues for a treatment of belief as essentially sensitive to certain features of context. The first part gives an argument that we must take belief to be context-sensitive in the same way that assertion is, if we are to preserve appealing principles tying belief to sincere assertion. In particular, whether an agent counts as believing that p in a context depends on the space of alternative possibilities the agent is considering in that context. One and the same doxastic (...) state may amount to belief that p in one context but not another. The second part of the paper gives a formal treatment of doxastic states, according to which belief is context-sensitive along just these lines. The model is applied to characterize (but not to refute) skeptical arguments. (shrink)

The preface paradox does not show that it can be rational to have inconsistent beliefs, because preface writers do not have inconsistent beliefs. I argue, first, that a fully satisfactory solution to the preface paradox would have it that the preface writer's beliefs are consistent. The case here is on basic intuitive grounds, not the consequence of a theory of rationality or of belief. Second, I point out that there is an independently motivated theory of belief – sensitivism – which (...) allows such a solution. I sketch a sensitivist account of the preface writer's doxastic state. (shrink)

Thompson Clarke’s seminal paper “The Legacy of Skepticism” (1972) is notoriously difficult in both substance and presentation. Despite the paper’s importance to skepticism studies in the nearly half-century since its publication, no attempt has been made in the secondary literature to provide an account, based on a close reading of the text, of just what Clarke’s argument is. Furthermore, much of the existing literature betrays (or so it seems to me) fundamental misunderstandings of Clarke’s thought. In this (...) essay, I attempt to explain—concisely but comprehensively—Clarke’s overall argument in “The Legacy of Skepticism.”. (shrink)

As part of a review symposium on DARWIN'S ARGUMENT BY ANALOGY: FROM ARTIFICIAL TO NATURAL SELECTION (2021), the journal METASCIENCE invited Roger White, Jon Hodge and me to submit a response to the thoughtful commentaries on our book by Andrea Sullivan-Clarke, David Depew and Andrew Inkpen.

Visual illusions of number provide a means of investigating the rules and principles through which approximate number representations are formed. Here, we investigated the developmental trajectory of an important numerical illusion – the connectedness illusion, wherein connecting pairs of items with thin lines reduces their perceived number without altering continuous attributes of the collections. We found that children as young as 5 years of age are affected by the illusion and that the magnitude of the effect increased into adulthood. Moreover, (...) individuals with greater numerical acuity exhibited stronger connectedness illusions after controlling for age. Overall, these results suggest the approximate number system expects to enumerate over bounded wholes and doing so is a signature of its optimal functioning. (shrink)

On a now orthodox view, humans and many other animals possess a “number sense,” or approximate number system, that represents number. Recently, this orthodox view has been subject to numerous critiques that question whether the ANS genuinely represents number. We distinguish three lines of critique – the arguments from congruency, confounds, and imprecision – and show that none succeed. We then provide positive reasons to think that the ANS genuinely represents numbers, and not just non-numerical confounds or exotic substitutes for (...) number, such as “numerosities” or “quanticals,” as critics propose. In so doing, we raise a neglected question: numbers of what kind? Proponents of the orthodox view have been remarkably coy on this issue. But this is unsatisfactory since the predictions of the orthodox view, including the situations in which the ANS is expected to succeed or fail, turn on the kind of number being represented. In response, we propose that the ANS represents not only natural numbers, but also non-natural rational numbers. It does not represent irrational numbers, however, and thereby fails to represent the real numbers more generally. This distances our proposal from existing conjectures, refines our understanding of the ANS, and paves the way for future research. (shrink)

Joint actions often require agents to track others’ actions while planning and executing physically incongruent actions of their own. Previous research has indicated that this can lead to visuomotor interference effects when it occurs outside of joint action. How is this avoided or overcome in joint actions? We hypothesized that when joint action partners represent their actions as interrelated components of a plan to bring about a joint action goal, each partner’s movements need not be represented in relation to distinct, (...) incongruent proximal goals. Instead they can be represented in relation to a single proximal goal – especially if the movements are, or appear to be, mechanically linked to a more distal joint action goal. To test this, we implemented a paradigm in which participants produced finger movements that were either congruent or incongruent with those of a virtual partner, and either with or without a joint action goal (the joint flipping of a switch, which turned on two light bulbs). Our findings provide partial support for the hypothesis that visuomotor interference effects can be reduced when two physically incongruent actions are represented as mechanically interdependent contributions to a joint action goal.

Number Nativism is the view that humans innately represent precise natural numbers. Despite a long and venerable history, it is often considered hopelessly out of touch with the empirical record. I argue that this is a mistake. After clarifying Number Nativism and distancing it from related conjectures, I distinguish three arguments which have been seen to refute the view. I argue that, while popular, two of these arguments miss the mark, and fail to place pressure on Number Nativism. Meanwhile, a (...) third argument is best construed as a challenge: rather than refuting Number Nativism, it challenges its proponents to provide positive evidence for their thesis and show that this can be squared with apparent counterevidence. In response, I introduce psycholinguistic work on The Tolerance Principle (not yet considered in this context), propose that it is hard to make sense of without positing precise and innate representations of natural numbers, and argue that there is no obvious reason why these innate representations couldn’t serve as a basis for mature numeric conception.

According to what may be called PERMANENT, blameworthiness is forever: once you are blameworthy for something, you are always blameworthy for it. Here a prima facie case for this view is set out, and the view is defended from two lines of attack. On one, you are no longer blameworthy for a past offense if, despite being the person who committed it, you no longer have any of the pertinent psychological states you had at the time of the misdeed. On (...) the other, you can cease to be blameworthy if you sufficiently experience guilt or remorse, suffer enough punishment, or are forgiven for your misdeed. Although several points made in support of the second challenge are accepted, they are entirely consistent with PERMANENT. Neither line of attack, as so far presented, undermines the plausibility of this view stemming from the prima facie case. (shrink)

Consider cases in which an agent simply doesn.t think to do a certain thing, or doesn't think of a crucial consideration favoring doing a certain thing, or intends to do a certain thing but forgets to do it. In such a case, is the agent able to do the thing that she fails to do? Assume that commonly we all‐in can do things that we do not do. Here I argue that, given this assumption, in the cases under consideration, too, (...) commonly agents all‐in can do the things they fail to do. (shrink)

Merleau-Ponty suggests in his Nature lectures that myth provides the best way into thinking the relation of strange kinship between humanity and animality. He goes on to refigure Husserl’s paradigm of the two hands touching to extend beyond merely human-to-human relations, invoking in the process the myth of Narcissus. By carefully examining Merleau-Ponty’s late refiguration of that paradigm, alongside the revised conception of narcissism that it helps him to develop, we find that while human-animal empathy is made possible by a (...) ground of intercorporeal kinship, human-animal estrangement makes possible the emergence of an ethical relation to other animals, contingent upon the sublimation of animal desire. Holding human-animal kinship and estrangement in tension reveals a nascent ideal present implicitly in the early stages of childhood development: a vision of the possibility of interspecies harmony, rooted in the bodily reciprocity that drives the process of self-maturation.

Holly Smith has done more than anyone to explore and defend the importance of usability for moral theories. In Making Morality Work, she develops a moral theory that is almost universally usable. But not quite. In this article, I argue that no moral theory is universally usable, in the sense that is most immediately relevant to action, even by agents who know all the normative facts. There is no moral theory knowledge of which suffices to settle deliberation about what to (...) do. However, this is unsurprising if the question of what to do is not a question of fact. One upshot of the discussion is that the search for a universally usable moral theory is misconceived. Another is that, contra Smith (341), agents who are radically uncertain need not lack autonomy.

Spinoza’s attitude toward nonhuman animals is uncharacteristically cruel. This essay elaborates upon this ostensible idiosyncrasy in reference to Hasana Sharp’s commendable desire to revitalize a basis for animal ethics from within the bounds of his system. Despite our favoring an ethics beginning from animal affect, this essay argues that an animal ethic adequate to the demands of our historical moment cannot be developed from within the confines of strict adherence to Spinoza’s system—and this is not yet to speak of a (...) more robust animal ethics which would advocate actual care and compassion for the animals themselves. We argue that on the assumption of Spinoza’s ontological biocentrism, in the presence of Spinozist determinism and the absence of an axiological biocentrism, an anthropocentric axiology necessarily follows. Any Spinozist animal ethic must fall back, therefore, upon appeals to the maximization of human pleasure and power; hence Spinoza’s ruthless injunction to “use (the animals) at our pleasure.” These are the very ontological and ethical assumptions which have incited human self-exaltation in the modern period, in pursuit of power and pleasure even despite the destructive long-term consequences for all the living. We suggest that an adequate animal ethic would require either an abandonment of Spinoza’s ontological biocentrism or the adoption of an axiological biocentrism. (shrink)

I discuss methodology in epistemology. I argue that settling the facts, even the epistemic facts, fails to settle the questions of intellectual policy at the center of our epistemic lives. An upshot is that the standard methodology of analyzing concepts like knowledge, justification, rationality, and so on is misconceived. More generally, any epistemic method that seeks to issue in intellectual policy by settling the facts, whether by way of abductive theorizing or empirical investigation, no matter how reliable, is inapt. The (...) argument is a radicalization of Moore’s Open Question Argument. I conclude by considering the ramifications of this conclusion for the debate surrounding “Modal Security”, a proposed necessary condition on undermining defeat. (shrink)

Consider the idea that suffering of some specific kind is deserved by those who are guilty of moral wrongdoing. Feeling guilty is a prime example. It might be said that it is noninstrumentally good that one who is guilty feel guilty (at the right time and to the right degree), or that feeling guilty (at the right time and to the right degree) is apt or fitting for one who is guilty. Each of these claims constitutes an interesting thesis about (...) desert, given certain understandings of what desert is. After examining these claims, the paper briefly explores the idea that an offender might deserve certain forms of treatment by others. The paper concludes by contrasting the modest theses on which it focuses with a far bolder one, to the effect that if we are morally responsible, then it makes sense to suppose that some of us might deserve to suffer eternal torment. The more modest theses do not commit one to anything of this sort. (shrink)

Friedrich Nietzsche and Albert Schweitzer end up defending radically similar, yet critically opposed conclusions about the human animal and its place in nature, particularly with regard to the ethical awareness that does or does not follow from this situatedness. Arthur Schopenhauer’s notion of the will accounts for their similar foundational assumptions. But what accounts for the fact that their shared desire to affirm the will to life leads to fundamentally opposed ethical conclusions? What keeps Schweitzer’s ascetic ethic of reverence for (...) life from evolving into Nietzsche’s anti-ascetic vision of a second innocence beyond good and evil? We argue that situating the notion of reverence for life within an environmental virtue ethics, as one environmental virtue among many, aiming at ecological conversion, better articulates and motivates the disposition demanded by the ethics of reverence for life.

Is God a person, like you and me eventually, but only much better and without our human deficiencies? When you read some of the philosophers of religion, including Richard Swinburne, Alvin Plantinga, or Open Theists, God appears as such a person, in a sense closer to Superman than to the Creator of Heaven and Earth. It is also a theory that a Christian pastoral theology today tends to impose, insisting that God is close to us and attentive to all of (...) us. But this modern account of God could be a deep and even tragic mistake. One God in three persons, the formula of the Trinity, does not mean that God is a person. On this matters we need an effort in the epistemology of theology to examine more precisely what we can pretend to know about God, and especially how we could pretend to know that God is person.

The approximate number system (ANS) enables organisms to represent the approximate number of items in an observed collection, quickly and independently of natural language. Recently, it has been proposed that the ANS goes beyond representing natural numbers by extracting and representing rational numbers (Clarke & Beck, 2021a). Prior work demonstrates that adults and children discriminate ratios in an approximate and ratio-dependent manner, consistent with the hallmarks of the ANS. Here, we use a well-known “connectedness illusion” to provide evidence that (...) these ratio-dependent ratio discriminations are (a) based on the perceived number of items in seen displays (and not just non-numerical confounds), (b) are not dependent on verbal working memory, or explicit counting routines, and (c) involve representations with a part-whole (or subset-superset) format, like a fraction, rather than a part-part format, like a ratio. These results vindicate key predictions of the hypothesis that the ANS represents rational numbers. (shrink)

It is often assumed that adaptation — a temporary change in sensitivity to a perceptual dimension following exposure to that dimension — is a litmus test for what is and is not a “primary visual attribute”. Thus, papers purporting to find evidence of number adaptation motivate a claim of great philosophical significance: That number is something that can be seen in much the way that canonical visual features, like color, contrast, size, and speed, can. Fifteen years after its reported discovery, (...) number adaptation’s existence seems to be nearly undisputed, with dozens of papers documenting support for the phenomenon. The aim of this paper is to offer a counterweight — to critically assess the evidence for and against number adaptation. After surveying the many reasons for thinking that number adaptation exists, we introduce several lesser-known reasons to be skeptical. We then advance an alternative account — the old news hypothesis — which can accommodate previously published findings while explaining various (otherwise unexplained) anomalies in the existing literature. Next, we describe the results of eight pre-registered experiments which pit our novel old news hypothesis against the received number adaptation hypothesis. Collectively, the results of these experiments undermine the number adaptation hypothesis on several fronts, whilst consistently supporting the old news hypothesis. More broadly our work raises questions about the status of adaptation itself as a means of discerning what is and is not a visual attribute. (shrink)

critical analyses of the arguments and attitudes favoring the various popular datings of the inception of a human being's life.

The ontological paradigms of Schelling and the late Merleau-Ponty bear striking resemblances to Spinoza’s ontology. Both were developed in response to transcendental models of a Cartesian mold, resisting tendencies to exalt the human ego to the neglect or the detriment of the more-than-human world. As such, thinkers with environmental concerns have sought to derive favorable ethical prescriptions on their basis. We begin by discerning a deadlock between two such thinkers: Ted Toadvine and Sean McGrath. With ecological responsibility in mind, both (...) actually resist Spinozist reduction of the human being to the status of a mere mode among modes. But despite having the same general aim, they end up endorsing contrary practical conclusions. Our objective is to pinpoint the reasons behind this deadlock, indicative of two strands of post-Spinozist environmental thought which stand in tension, and to begin to propose an integrative way forward. The ethical weight afforded by Toadvine to the notion of resistance in the work of the late Merleau-Ponty, namely nature’s resistance to harmonizing, unifying pretensions, invites inquiry into two Merleau-Pontean notions he does not address: the barbarian principle, and the proposal to “Do a Psychoanalysis of Nature.” We trace these to their origins in the works of Schelling’s middle period, arguing that the Schellingian location of resistance in Spirit’s dark ground—alternately conceived as primordial Dionysiac madness, bottled-up within the substratum of consciousness—lends to an understanding of the human, and human responsibility, that harbors favorable implications for environmental ethics.

Buchanan and Powell hope to rescue optimism about moral perfectibility from the ’received view’ of human evolution, by tweaking our view of the innate character of morality. I argue that their intervention is hampered by an unnecessary commitment to nativism, by gender bias within the received view, and by liberal presuppositions.

Our culture is conflicted about morally judging and condemning. We can't avoid it altogether, yet many layfolk today are loathe to do it for reasons neither they nor philosophers well understand. Their resistance is often confused (by themselves and by theorists) with some species of antiobjectivism. But unlike a nonobjectivist, most people think that (a) for us to judge and condemn is generally (objectively) morally wrong , yet (b) for God to do so is (objectively) proper, and (c) so too (...) for certain persons in certain relations (e.g., self-condemnation, parental child rearing.) Certainly, religious (e.g., Christian) critics of judging and condemning without doubting the objective truth of their tradition's core moral teachings. Most puzzling is that (a) merely judging and condemning in one's heart may be improper, and (b) someone else with no more evidence or expertise might properly judge and condemn the same action. The answer is in condemning's complex structure of presuppostions. Condemning and judging are acts, and attitudes initiated by the act. Condemnation is motivated by two judgments presumed to justify it, a criticism of a target, and a judgment that the criticism justifies some negative response toward the target. Unlike nonpunitive penalties, punishments are motivated and explained by condemnation. Condemnation is an act of a hostile will, wishing some evil for its target, not (just) as a means to some good. Its root is in damning, an act akin to cursing. It declares a degraded status. The hostility makes it harder to justify condemnation than criticism, and punishment than nonpunitive penalties. Condemning claims objectivity and authority. It involves reflexive evaluation, regarding itself justified, approving its hostile feelings toward the target. Condemners presume themselves entitled to sit in judgment, pass judgment, and cast the condemned down. Those presumptions inhere in sitting in judgment, assuming jurisdiction. Unlike mathematical or scientific judgments, passing moral judgment seems to be a political act subject to extraepistemic constraints. "Who are you to judge?" may properly challenge your right to pass judgment. (shrink)

This chapter is a contribution to an exchange with Carolina Sartorio about intentional omissions.

A recent empirical study claims to show that the answer to Molyneux’s question is negative, but, as John Schwenkler points out, its findings are inconclusive: Subjects tested in this study probably lacked the visual acuity required for a fair assessment of the question. Schwenkler is undeterred. He argues that the study could be improved by lowering the visual demands placed on subjects, a suggestion later endorsed and developed by Kevin Connolly. I suggest that Connolly and Schwenkler both underestimate the difficulties (...) involved in rectifying the study they seek to fix. The problem is that the experimental paradigm under consideration fails to account for the role that rational inference plays in newly sighted subjects’ ability or inability to recognize spatial properties across modalities. Since answering Molyneux’s question requires establishing whether spatial properties can be recognized, across modalities, by newly sighted subjects without recourse to rational inference, this is a problem. Indeed, it is a problem that may be worsened by Schwenkler and Connolly’s suggestions regarding the lowering of visual demands on subjects in cross-modal matching tasks. (shrink)

Many healthcare practices expose people to risks of harmful outcomes. However, the major theories of moral philosophy struggle to assess whether, when and why it is ethically justifiable to expose individuals to risks, as opposed to actually harming them. Sven Ove Hansson has proposed an approach to the ethical assessment of risk imposition that encourages attention to factors including questions of justice in the distribution of advantage and risk, people’s acceptance or otherwise of risks, and the scope individuals have to (...) influence the practices that generate risk. This paper investigates the ethical justifiability of preventive healthcare practices that expose people to risks including overdiagnosis. We applied Hansson’s framework to three such practices: an ‘ideal’ breast screening service, a commercial personal genome testing service, and a guideline that lowers the diagnostic threshold for hypertension. The framework was challenging to apply, not least because healthcare has unclear boundaries and involves highly complex practices. Nonetheless, the framework encouraged attention to issues that would be widely recognised as morally pertinent. Our assessment supports the view that at least some preventive healthcare practices that impose risks including that of overdiagnosis are not ethically justifiable. Further work is however needed to develop and/or test refined assessment criteria and guidance for applying them. (shrink)

Financial sustainability of protected areas is one of the main challenges of management. Financial self-sufficiency is an important element in improving conservation effort in these areas. This study seeks to review best practices in recreational fee systems in different countries and to find a relevant entry fee for a wildlife sanctuary in Malaysia. The revenue of the National Elephant Conservation Center (NECC) in Kuala Gandah, Malaysia, comes from several sources, including the national government, but all these budgetary sources are strained (...) by tighter public budgets and greater demands. The present study investigates the introduction of visitor entrance fees to supplement an otherwise inadequate budget for supporting the operational costs of the sanctuary. Factor analysis and a double-bounded contingent valuation method were combined to estimate tourists' willingness to pay (WTP) the proposed entrance fee. Factor analysis showed that respondents' motivation to support the NECC with user fees is conditioned by their direct experiences with elephants, their satisfaction with NECC's educational programs and services, and other experiences it gives to users. The WTP model considered respondents' four motivation factors with their sociodemographic characteristics. Since NECC visitors arrive from both within and outside the country, this study suggests to center managers a two-tier fee structure (residents vs. nonresidents of Malaysia), based upon mean WTP estimates. This study further suggests that revenue from such an entrance fee for NECC could support the Center's management and development costs. © 2015 Elsevier B. (shrink)

Critical analysis of Roe v Wade Supreme Court decision.

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.

Between Schelling’s Über Dante in philosophischer Beziehung (1803) and the Dantean drafts of die Weltalter (1811-1815) stand the transitional texts of his middle period, the Philosophie und Religion (1804) and Freiheitsschrift (1809). His short essay on Dante contrasts an ancient conception of the closed cosmos with the modern universe as dynamic and expanding, then claims to extract from the Divine Comedy its eternal, threefold form. This article considers these schemata as they relate to the Philosophie und Religion and the Freiheitsschrift, (...) disclosing an enduring Dantean influence which first predicts, then persists throughout this stage of Schelling’s philosophical development.

Neuroeconomics is a research programme founded on the thesis that cognitive and neurobiological data constitute evidence for answering economic questions. I employ confirmation theory in order to reject arguments both for and against neuroeconomics.

I then argue for neuroeconomics by appealing to a much more restrictive (and thereby skeptic-friendly) characterization (...) of the aims of economics. (shrink)

Objective We reviewed human–robot interaction (HRI) participatory design (PD) research with older adults. The goal was to identify methods used, determine their value for design of robots with older adults, and provide guidance for best practices. Background Assistive robots may promote aging-in-place and quality of life for older adults. However, the robots must be designed to meet older adults’ specific needs and preferences. PD and other user-centered methods may be used to engage older adults in the robot development process to (...) accommodate their needs and preferences and to assure usability of emergent assistive robots. Method This targeted review of HRI PD studies with older adults draws on a detailed review of 26 articles. Our assessment focused on the HRI methods and their utility for use with older adults who have a range of needs and capabilities. Results Our review highlighted the importance of using mixed methods and including multiple stakeholders throughout the design process. These approaches can encourage mutual learning (to improve design by developers and to increase acceptance by users). We identified key phases used in HRI PD workshops (e.g., initial interview phase, series of focus groups phase, and presentation phase). These approaches can provide inspiration for future efforts. Conclusion HRI PD strategies can support designers in developing assistive robots that meet older adults’ needs, capabilities, and preferences to promote acceptance. More HRI research is needed to understand potential implications for aging-in-place. PD methods provide a promising approach. (shrink)

A large chorus of voices has grown around the claim that theistic belief is epistemically suspect since, as some cognitive scientists have hypothesized, such beliefs are a byproduct of cognitive mechanisms which evolved for rather different adaptive purposes. This paper begins with an overview of the pertinent cognitive science followed by a short discussion of some relevant epistemic concepts. Working from within a largely Williamsonian framework, we then present two different ways in which this research can be formulated into an (...) argument against theistic belief.

Explaining the behaviour of ecosystems is one of the key challenges for the biological sciences. Since 2000, new-mechanicism has been the main model to account for the nature of scientific explanation in biology. The universality of the new-mechanist view in biology has been however put into question due to the existence of explanations that account for some biological phenomena in terms of their mathematical properties (mathematical explanations). Supporters of mathematical explanation have argued that the explanation of the behaviour of ecosystems (...) is usually provided in terms of their mathematical properties, and not in mechanistic terms. They have intensively studied the explanation of the properties of ecosystems that behave following the rules of a non-random network. However, no attention has been devoted to the study of the nature of the explanation in those that form a random network. In this paper, we cover that gap by analysing the explanation of the stability behaviour of the microbiome recently elaborated by Coyte and colleagues, to determine whether it fits with the model of explanation suggested by the new-mechanist or by the defenders of mathematical explanation. Our analysis of this case study supports three theses: (1) that the explanation is not given solely in terms of mechanisms, as the new-mechanists understand the concept; (2) that the mathematical properties that describe the system play an essential explanatory role, but they do not exhaust the explanation; (3) that a non-previously identified appeal to the type of interactions that the entities in the network can exhibit, as well as their abundance, is also necessary for Coyte and colleagues’ account to be fully explanatory. From the combination of these three theses we argue for the necessity of an integrative pluralist view of the nature of behaviour explanation when this is given by appealing to the existence of a random network.

Effective Altruism is a social movement which encourages people to do as much good as they can when helping others, given limited money, time, effort, and other resources. This paper first identifies a minimal philosophical view that underpins this movement, and then argues that there is an analogous minimal philosophical view which might underpin Effective Justice, a possible social movement that would encourage promoting justice most effectively, given limited resources. The latter minimal view reflects an insight about justice, and our (...) non-diminishing moral reason to promote more of it, that surprisingly has gone largely unnoticed and undiscussed. The Effective Altruism movement has led many to reconsider how best to help others, but relatively little attention has been paid to the differences in degrees of cost-effectiveness of activities designed to decrease injustice. This paper therefore not only furthers philosophical understanding of justice, but has potentially major practical implications. (shrink)

Consistent materialists are almost bound to suggest that , if it exists at all, is no more than epiphenomenal. A correct understanding of the real requires that everything we do and say is no more than a product of whatever processes are best described by physics, without any privileged place, person, time or scale of action. Consciousness is a myth, or at least a figment. Plotinus was no materialist: for him, it is Soul and Intellect that are more real than (...) the phenomena we misdescribe as material. Nor does he suppose that consciousness depends on language (as Stoics and modern materialists have sometimes said): wordless experience is actually superior. And much of what counts towards our present consciousness is to be discarded. It is better not to remember most of what now seems more significant to us; better to discard images; better that the intellect be than , losing any sense of separation between subject and object. The goal of the Plotinian intellectual is to join , but it is a mark of the good dancer that she is not conscious of what she does. There is therefore a strange confluence between Plotinus and modern materialists: our experience at least is transitory, deceitful, epiphenomenal, and is to be encountered when we have shed our illusions.

Some recent exchanges (Gebharter 2017a,2017b; Baumgartner and Cassini, 2023) concern whether composition can have conditional independence properties analogous to causal relations. If so, composition might sometimes be detectable by the application of causal search algorithms. The discussion has focused on a particular algorithm, PC (Spirtes and Glymour, 1991). PC is but one, and in many circumstances not the best, of a host of causal search algorithms that are candidates for methods of discovering composition provided appropriate statistical relations obtain. The discussion (...) raises two issues: 1. Does the structure of the composition relation entail probability relations such that PC and like algorithms cannot discover composition from frequency data about kinds; and 2. what can be discovered—and how—about the composition of systems by PC or related causal search algorithms that exploit conditional independence relations. Baumgartner and Cassini answer the first question positively: constitution entails probability relations incompatible with discovery by PC. They do not engage the second question, but we will.

View more Abstract If logical truth is necessitated by sheer syntax, mathematics is categorially unlike logic even if all mathematics derives from definitions and logical principles. This contrast gets obscured by the plausibility of the Synonym Substitution Principle implicit in conceptions of analyticity: synonym substitution cannot alter sentence sense. The Principle obviously fails with intercepting: nonuniform term substitution in logical sentences. ‘Televisions are televisions’ and ‘TVs are televisions’ neither sound alike nor are used interchangeably. Interception synonymy gets assumed because logical (...) sentences and their synomic interceptions have identical factual content, which seems to exhaust semantic content. However, intercepting alters syntax by eliminating term recurrence, the sole strictly syntactic means of ensuring necessary term coextension, and thereby syntactically securing necessary truth. Interceptional necessity is lexical, a notational artifact. The denial of interception nonsynonymy and the disregard of term recurrence in logic link with many misconceptions about propositions, logical form, conventions, and metalanguages.
