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)

The visual system adapts to a wide range of visual features, from lower-level features like color and motion to higher-level features like causality and, perhaps, number. According to some, adaptation is a strictly perceptual phenomenon, such that the presence of adaptation licenses the claim that a feature is truly perceptual in nature. Given the theoretical importance of claims about adaptation, then, it is important to understand exactly when the visual system does and does not exhibit adaptation. Here, we take as (...) a case study one specific kind of adaptation: visual adaptation to size. Supported by evidence from four experiments, we argue that, despite robust effects of size adaptation in the lab, (1) size adaptation effects are phenomenologically underwhelming (in some cases, hardly appreciable at all), (2) some effects of size adaptation appear contradictory, and difficult to explain given current theories of size adaptation, and (3) prior studies on size adaptation may have failed to isolate size as the adapted dimension. Ultimately, we argue that while there is evidence to license the claim that size adaptation is genuine, size adaptation is a puzzling and poorly understood phenomenon. (shrink)

Abstract Following Clarke (2002), a Lakatosian approach is used to account for the epistemic development of conspiracy theories. It is then argued that the hypercritical atmosphere of the internet has slowed down the development of conspiracy theories, discouraging conspiracy theorists from articulating explicit versions of their favoured theories, which could form the hard core of Lakatosian research pro grammes. The argument is illustrated with a study of the “controlled demolition” theory of the collapse of three towers at the World (...) Trade Center on September 11, 2001. (shrink)

Dispositions can be finkish, prone to disappear in circumstances that would commonly trigger their characteristic manifestations. Can a disposition be finkish because of something intrinsic to the object possessing that disposition? Sungho Choi has argued that this is not possible, and many agree. Here it is argued that no good case has been made for ruling out the possibility of intrinsic finks; on the contrary, there is good reason to accept it.

This comprehensive study offers a balanced assessment of libertarian accounts of free will. Bringing to bear recent work on action, causation, and causal explanation, Clarke defends a type of event-causal view from popular objections concerning rationality and diminished control. He subtly explores the extent to which event-causal accounts can secure the things for the sake of which we value free will, judging their success here to be limited. Clarke then sets out a highly original agent-causal account, one that (...) integrates agent causation and nondeterministic event causation. He defends this view from a number of objections but argues that we should find the substance causation required by any agent-causal account to be impossible. Clarke concludes that if a broad thesis of incompatibilism is correct--one on which both free will and moral responsibility are incompatible with determinism--then no libertarian account is entirely adequate.

: On a standard libertarian account of free will, an agent acts freely on some occasion only if there remains, until the action is performed, some chance that the agent will do something else instead right then. These views face the objection that, in such a case, it is a matter of luck whether the agent does one thing or another. This paper considers the problem of luck as it bears on agent‐causal libertarian accounts. A view of this type is (...) defended against a recent and challenging version of the argument from luck.

To what extent are the subjects of our thoughts and talk real? This is the question of realism. In this book, Justin Clarke-Doane explores arguments for and against moral realism and mathematical realism, how they interact, and what they can tell us about areas of philosophical interest more generally. He argues that, contrary to widespread belief, our mathematical beliefs have no better claim to being self-evident or provable than our moral beliefs. Nor do our mathematical beliefs have better claim (...) to being empirically justified than our moral beliefs. It is also incorrect that reflection on the "genealogy" of our moral beliefs establishes a lack of parity between the cases. In general, if one is a moral antirealist on the basis of epistemological considerations, then one ought to be a mathematical antirealist as well. And, yet, Clarke-Doane shows that moral realism and mathematical realism do not stand or fall together -- and for a surprising reason. Moral questions, insofar as they are practical, are objective in a sense that mathematical questions are not. Moreover, the sense in which they are objective can be explained only by assuming practical anti-realism. One upshot of the discussion is that the concepts of realism and objectivity, which are widely identified, are actually in tension. Another is that the objective questions in the neighborhood of questions of logic, modality, grounding, and nature are practical questions too. Practical philosophy should, therefore, take center stage. (shrink)

The manner in which the phenomenological method has been applied to the data of ethics by Max Scheler, and his resulting criticisms of the formalism of classical theories of an absolute good and the subjectivity and relativity of the opposing “content theories,” have been discussed in a previous article. It is the purpose of the present paper to present Scheler’s claim to have resolved this dilemma in ethics by laying bare a structure of value too often obscured by the series (...) of falsifications and confusions that he has exposed.

Since the appearance, nearly twenty years ago, of the first volume of Husserl”s Jahrbuch für Philosophie und phänomenologische Forschung , philosophers have been watching the development of a movement in Germany that has claimed attention through its opposition on the one side to the still powerful Kantian tradition, on the other to the trend of thought arising under the influence of biological science, aptly named by Meinong Psychologismus . The subtlety and originality of this new line of speculation and the (...) exactness of its method have attracted to it some of the most powerful intellects of the country, whose contributions would repay a more detailed study than they have yet received from English or American scholars.

This paper examines libertarian accounts that appeal to event causation but avoid appeal to agent causation. Such views are modest in their metaphysical commitments and may be modest, as well, in what they promise. It is argued that an action-centered version should be preferred; on such a view, indeterminism is required in the direct production of decision or other action. Although a view of this kind does not improve on compatibilist accounts when it comes to moral responsibility, they may be (...) preferable in other respects. (shrink)

W. Norris Clarke's metaphysics of the universe as a journey rests on six major positions: the unrestricted dynamism of the mind, the primacy of the act of existence, the participation structure of reality, and the person, considered as both the starting point of philosophy and the source of the categories needed for a flexible contemporary metaphysics. Reflecting on his conscious life and the universe around him, the finite person mounts by a two-fold path to its Infinite source, who, though (...) immutable in His natural being, is mutable in the intentional being of His personal knowledge and love. The personal God is the efficient cause from whom the universe comes and the final cause to whom it returns.Less optimistic than Norris Clarke, John Caputo wonders about his metaphysics of the person. In a hermeneutical interpretation of the human face, the person through whom Being "sounds" discloses an ambiguous Being that both reveals and conceals itself. Far from grounding a casual ascent to God, hermeneutical phenomenology allows us no more than the right to interpret the world and its transcendent source through our own free decision.Although impressed by Norris Clarke's attempt to introduce mutability into God, Lewis Ford still finds Clarke's Thomistic God unacceptable. As a Whiteheadian, he proposes in place of Thomas' God, whose perfection consists in static unity, a God whose perfection consists in a never-ending process of unification. John Smith argues against the traditional dichotomy made between the ontological and cosmological arguments. Rather than opposed methods of proving God's existence, they should be taken as complementary journeys to the divine presence which discloses itself, although diversely, in the soul and in the world. There are parallels between Smith's historical study of two arguments and Clarke's two-fold path to God. Yet Smith is critical of Thomas' cosmological journey to God and does not share Clarke's confidence in its validity. Significant studies in their own right, the three essays as a group challenge Clarke's whole metaphysics of the universe as a journey. Meeting the challenge, Clarke clarifies and refines his own thought.An account of Clarke's philosophy by Gerald A. McCool, S.J. preceds this unified and stimulating philosophical discussion.

In a recent paper, Berger and Nanay consider, and reject, three ways of addressing the phenomenon of unconscious perception within a naïve realist framework. Since these three approaches seem to exhaust the options open to naïve realists, and since there is said to be excellent evidence that perception of the same fundamental kind can occur, both consciously and unconsciously, this is seen to present a problem for the view. We take this opportunity to show that all three approaches considered remain (...) perfectly plausible ways of addressing unconscious perception within a naïve realist framework. So far from undermining the credibility of naïve realism, Berger and Nanay simply draw our attention to an important question to be considered by naïve realists in future work. Namely, which of the approaches considered is most likely to provide an accurate account of unconscious perception in each of its purported incarnations? (shrink)

The dominant view in the cognitive science of religion (the ‘Standard Model’) is that religious belief and behaviour are not adaptive traits but rather incidental byproducts of the cognitive architecture of mind. Because evidence for the Standard Model is inconclusive, the case for it depends crucially on its alleged methodological superiority to selectionist alternatives. However, we show that the Standard Model has both methodological and evidential disadvantages when compared with selectionist alternatives. We also consider a pluralistic approach, which holds that (...) religion or various aspects of religion originated as byproducts of evolved cognitive structures but were subsequently co-opted for adaptive purposes. We argue that when properly formulated, the pluralistic approach also has certain advantages over the Standard Model. (shrink)

Nonreductive physicalism is currently one of the most widely held views about the world in general and about the status of the mental in particular. However, the view has recently faced a series of powerful criticisms from, among others, Jaegwon Kim. In several papers, Kim has argued that the nonreductivist's view of the mental is an unstable position, one harboring contradictions that push it either to reductivism or to eliminativism. The problems arise, Kim maintains, when we consider the causal powers (...) that mental properties are held to carry on the nonreductivist's view and the causal transactions into which mental events are said to enter. My aim here is less than that of defending nonreductive physicalism against all of Kim's criticisms. I wish primarily to call into question the claim that nonreductive physicalism is committed to emergentism with respect to the causal powers of the mental. As subsidiary points, I shall offer a limited defense of nonreductivism against two related objections that Kim raises. However, even if my conclusions are correct, problems remain for the nonreductivist's treatment of mental causation. I shall close the paper with a brief discussion of these difficulties. (shrink)

In the highly contentious abortion arena, the new oral abortifacient technology RU486 is one among many actors. This article offers an arena analysis of the heterogeneous constructions of RU486 by various actors, including scientists, pharmaceutical compa nies, medical groups, antiabortion groups, women's health movement groups, and others who have produced situated knowledges. Conceptually, we find not only that the identity of the nonhuman actor-RU486 -is unstable and multiple but also that, in practice, there are other implicated actors—the downstream users and (...) consumers of the technology. If we try to follow all the actors, we find a fuller and more historicized arena, and, ironically, we too can be construed as implicated actors in it. (shrink)

Nurses are responsible for the well-being and quality of life of many people, and therefore must meet high standards of technical and ethical competence. The most common form of ethical guidance is a code of ethics/professional practice; however, little research on how codes are viewed or used in practice has been undertaken. This study, carried out in six European countries, explored nurses’ opinions of the content and function of codes and their use in nursing practice. A total of 49 focus (...) groups involving 311 nurses were held. Purposive sampling ensured a mix of participants from a range of specialisms. Qualitative analysis enabled emerging themes to be identified on both national and comparative bases. Most participants had a poor understanding of their codes. They were unfamiliar with the content and believed they have little practical value because of extensive barriers to their effective use. In many countries nursing codes appear to be ‘paper tigers’ with little or no impact; changes are needed in the way they are developed and written, introduced in nurse education, and reinforced/implemented in clinical practice.

In the aftermath of emotivism and behaviourism, cognitivist theories of emotion became current in both philosophy and psychology. These theories, though varied, have in common that emotions require propositional attitudes such as beliefs or evaluations. Accordingly, cognitivist theories characterize emotions themselves with features of such attitudes, including syntax, semantic meaning, and justifiability.

A contrastive rational explanation of a choice cites a reason why the agent made that choice rather than, say, making a different choice, or rather than making no choice at all. It is often said that if, as libertarians maintain, free choices are undetermined by prior events, then it is not possible to provide contrastive rational explanations of them. Alternatively, it is sometimes said that while non-causal contrastive rational explanation of such a choice might be possible, causal contrastive rational explanation (...) is not. Here it is argued that the libertarian requirement is no bar to causal contrastive rational explanation of free choice. (shrink)

This paper examines the libertarian account of free choice advanced by Robert Kane in his recent book, The Significance of Free Will. First a rather simple libertarian view is considered, and an objection is raised against it the view fails to provide for any greater degree of agent-control than what could be available in a deterministic world. The basic differences between this simple view and Kane's account are the requirements, on the latter, of efforts of will and of an agent's (...) wanting more to do a certain thing than he wants to do anything else. It is argued here that neither of these features yields any improvement over the simple libertarian view; neither helps to meet the objection that was raised against the simple view. Finally, it is suggested that a modest defense of that view might be available. (shrink)

Imagine hosting a party. You arrange snacks, curate a playlist and place a variety of beers in the refrigerator. Your first guest shows up, adding a six-pack before taking one bottle for himself. You watch your next guest arrive and contribute a few more beers, minus one for herself. Ready for a drink, you open the fridge and are surprised to find only eight beers remaining. You haven't been consciously counting the beers, but you know there should be more, so (...) you start poking around. Sure enough, in the crisper drawer, behind a rotting head of romaine, are several bottles. (shrink)

Philosophical theories of agency have focused primarily on actions and activities. But, besides acting, we often omit to do or refrain from doing certain things. How is this aspect of our agency to be conceived? This book offers a comprehensive account of omitting and refraining, addressing issues ranging from the nature of agency and moral responsibility to the metaphysics of absences and causation. Topics addressed include the role of intention in intentional omission, the connection between negligence and omission, the distinction (...) between doing and allowing, and the distinction in law between act and omission.

In our target article, we argued that the number sense represents natural and rational numbers. Here, we respond to the 26 commentaries we received, highlighting new directions for empirical and theoretical research. We discuss two background assumptions, arguments against the number sense, whether the approximate number system represents numbers or numerosities, and why the ANS represents rational numbers.

Modern military organizations are paternalistic organizations. They typically recognize a duty of care toward military personnel and are willing to ignore or violate the consent of military personnel in order to uphold that duty of care. In this paper, we consider the case for paternalism in the military and distinguish it from the case for paternalism in medicine. We argue that one can consistently reject paternalism in medicine but uphold paternalism in the military. We consider two well-known arguments for the (...) conclusion that military organizations should not be entitled to use experimental drugs on troops without first obtaining the informed consent of those troops. We argue that both of these are unsuccessful, in the absence of an argument for the rejection of paternalism in the military altogether. The case for military paternalism is widely accepted. However, we consider three ways in which it could be challenged. (shrink)

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 two theses: that degrees of belief are context sensitive; that outright belief is belief to degree 1. The latter thesis is rejected quickly in most discussions of the relationship between credence and belief, but the former thesis undermines the usual reasons for doing so. Furthermore, identifying belief with credence 1 allows nice solutions to a number of problems for the most widely-held view of the relationship between credence and belief, the threshold view. I provide a sketch (...) of a formal framework on which both theses are true. This is a modified Bayesian framework; I argue that despite making credences context-sensitive, the framework lets Bayesians hold on to their signature explanatory successes. The sort of context-sensitivity claimed for credences here mirrors the sort of context-sensitivity I have elsewhere claimed for outright belief: one's credences depend, in part, on the space of alternative possibilities one takes seriously in a context.

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

This paper argues that the provision of effective informed consent by surgical patients requires the disclosure of material information about the comparative clinical performance of available surgeons. We develop a new ethical argument for the conclusion that comparative information about surgeons' performance - surgeons' report cards - should be provided to patients, a conclusion that has already been supported by legal and economic arguments. We consider some recent institutional and legal developments in this area, and we respond to some common (...) objections to the use of report cards on the clinical performance of surgeons. (shrink)

Both intention-based and causation-based definitions of the miraculous make reference to the term ‘supernatural’. Philosophers who define the miraculous appear to use this term in a loose way, perhaps meaning the nonnatural, perhaps meaning a subcategory of the nonnatural. Here I examine the aetiology of the term ‘supernatural’. I consider three outstanding issues regarding the meaning of the term and conclude that the supernatural is best understood as a subcategory of the nonnatural. In light of this clarification, I argue that (...) a prominent causation-based definition of the miraculous should be revised so as not refer to the supernatural. I further argue that authors of intention-based definitions of the miraculous need to consider whether or not they should continue to refer to the supernatural, in their definitions of the miraculous, in light of the conclusions discerned here.
