Scientific models need to be investigated if they are to provide valuable information about the systems they represent. Surprisingly, the epistemological question of what enables this investigation has hardly been investigated. Even authors who consider the inferential role of models as central, like Hughes or Bueno and Colyvan, content themselves with claiming that models contain mathematical resources that provide inferential power. We claim that these notions require further analysis and argue that mathematical formalisms contribute to this (...) class='Hi'>inferential role. We characterize formalisms, illustrate how they extend our mathematical resources, and highlight how distinct formalisms offer various inferential affordances. (shrink)

How do we construct ad hoc concepts, especially those characterised by emergent properties? A reasonable hypothesis, suggested both in psychology and in pragmatics , is that some sort of inferential processing must be involved. I argue that this inferential processing can be accounted for in associative terms. My argument is based on the notion of inference as associative pattern completion based on schemata, with schemata being conceived in turn as patterns of concepts and their relationships. The possible role (...) of conscious attention in inferential processes of this sort is also addressed. (shrink)

Reliability theories of epistemic justification face three main objections: the generality problem, the demon-world (or brain-in-a-vat) counterexample, and the clairvoyant-powers counterexample. In Perception and Basic Beliefs(Oxford 2009), Jack Lyons defends reliabilism at length against the clairvoyant powers case. He argues that the problem arises due to a laxity about the category of basic beliefs, and the difference between inferential and non-inferential justification. Lyons argues reliabilists must pay more attention to architecture. I argue this isn’t necessarily so. What really (...) matters for understanding and solving the case involves paying closer attention to the origins of our belief forming capacities, both inferential and non-inferential. Reliabilists should make origins matter more. (shrink)

The entire development of modern logic is characterized by various forms of confrontation of what has come to be called proof theory with what has earned the label of model theory. For a long time the widely accepted view was that while model theory captures directly what logical formalisms are about, proof theory is merely our technical means of getting some incomplete grip on this; but in recent decades the situation has altered. Not only did proof theory expand into new (...) realms, generalizing the concept of proof in various directions; many philosophers also realized that meaning may be seen as primarily consisting in certain rules rather than in language-world links. However, the possibility of construing meaning as an inferential role is often seen as essentially compromised by the limits of prooftheoretical means. The aim of this paper is to sort out the cluster of problems besetting logical inferentialism by disentangling and clarifying one of them, namely determining the power of various inferential frameworks as measured by that of explicitly semantic ones.

Among philosophers of science, there is now a widespread agreement that the DN model of explanation is poorly equipped to account for explanations in biology. Rather than identifying laws, so the consensus goes, researchers explain biological capacities by constructing a model of the underlying mechanism.We think that the dichotomy between DN explanations and mechanistic explanations is misleading. In this article, we argue that there are cases in which biological capacities are explained without constructing a model of the underlying mechanism. Although (...) these explanations do not conform to Hempel’s DN model, they do invoke more or less stable generalisations. Because they invoke generalisations and have the form of an argument, we call them inferential explanations. We support this claim by considering two examples of explanations of biological capacities: pigeon navigation and photoperiodism. Next, we will argue that these non-mechanistic explanations are crucial to biology in three ways: sometimes, they are the only thing we have, they are heuristically useful, and they provide genuine understanding and so are interesting in their own right.In the last sections we discuss the relation between types of explanations and types of experiments and situate our views within some relevant debates on explanatory power and explanatory virtues.

We advance a framework for an inferential conception of physical laws, addressing the problem of the application of mathematical structures to the relevant structure of physical domains. Physical laws, we argue, express generalizations that work as rules for deriving physically informative inferences about their target systems, hence guiding us in our interaction with various domains. Our analysis of the application of mathematics to the articulation of physical laws follows a threefold scheme. First, we examine the immersion of the relevant (...) structure of physical domains into mathematical structures. Second, we assess the inferential power of laws resulting from the mathematical formalism employed in the immersion step. And third, we provide a suitable physical interpretation for the extant mathematical structures obtained from the inferential step. We demonstrate that a deflationary, empiricist framework for an inferential conception of physical laws delivers both an understanding of the mathematical character of physical laws, and a way of responding to some of the standard philosophical riddles associated with laws.

Comparisons of rival explanations or theories often involve vague appeals to explanatory power. In this paper, we dissect this metaphor by distinguishing between different dimensions of the goodness of an explanation: non-sensitivity, cognitive salience, precision, factual accuracy and degree of integration. These dimensions are partially independent and often come into conflict. Our main contribution is to go beyond simple stipulation or description by explicating why these factors are taken to be explanatory virtues. We accomplish this by using the contrastive-counterfactual (...) approach to explanation and the view of understanding as an inferential ability. By combining these perspectives, we show how the explanatory power of an explanation in a given dimension can be assessed by showing the range of answers it provides to what-if-things-had-been-different questions and the theoretical and pragmatic importance of these questions. Our account also explains intuitions linking explanation to unification or to exhibition of a mechanism. (shrink)

In this article we defend the inferential view of scientific models and idealisation. Models are seen as “inferential prostheses” (instruments for surrogative reasoning) construed by means of an idealisation-concretisation process, which we essentially understand as a kind of counterfactual deformation procedure (also analysed in inferential terms). The value of scientific representation is understood in terms not only of the success of the inferential outcomes arrived at with its help, but also of the heuristic power of (...) representation and their capacity to correct and improve our models. This provides us with an argument against Sugden’s account of credible models: the likelihood or realisticness (their “credibility”) is not always a good measure of their acceptability. As opposed to “credibility” we propose the notion of “enlightening”, which is the capacity of giving us understanding in the sense of an inferential ability. (shrink)

Inferential statistical tests-such as analysis of variance, t-tests, chi-square and Wilcoxin signed ranks-now constitute a principal class of methods for the testing of scientific hypotheses. In this paper I will consider the role of one statistical concept (statistical power) and two statistical principles or assumptions (homogeneity of variance and the independence of random error), in the reliable application of selected statistical methods. I defend a tacit but widely-deployed naturalistic principle of explanation (E): Philosophers should not treat as inexplicable (...) or basic those correlational facts that scientists themselves do not treat as irreducible. In light of (E), I contend that the conformity of epistemically reliable statistical tests to these concepts and assumptions entails at least the following modest or austere realist commitment: (C) The populations under study have a stable theoretical or unobserved structure that metaphysically grounds the observed values; the objects therefore have a fixed value independent of our efforts to measure them. (C) provides the best explanation for the correlation between the joint use of statistical assumptions and statistical tests, on the one hand, and methodological success on the other. (shrink)

Information and Communication Technologies are intended to develop, maintain and administrate information using computer systems, communication networks, portable dispositives, etc. In addition to that, this paper deals with ICT’s power to create new contexts: what is called digital ambiences. According to the author the design and even the concept of these intelligent ambiences has problems that have to do both with the use of reasoning and the display of inferential and interpretative processes to interact with the social context (...) in an individual or a collective way. Solving these philosophical problems could guide the development and implantation of ubiquitous and embodied technologies that would be able to amplify the cognitive and motive capacity of people.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Semantic Powers: Meaning and the Means of Knowing in Classical Indian PhilosophyHarold CowardSemantic Powers: Meaning and the Means of Knowing in Classical Indian Philosophy. By Jonardon Ganeri. Oxford: Oxford University Press, 1999. Pp. x + 266.In Semantic Powers: Meaning and the Means of Knowing in Classical Indian Philosophy, Jonardon Ganeri adds to our understanding of the Nyāya philosophy of language in the modern English-speaking world. Building on Bimal (...) Matilal's introduction to Nyāya thought in Matilal's foundational Epistemology Logic and Grammar in Indian Philosophical Analysis (1971) and on Karl Potter and Sibajiban Bhattacharyya's Nyāya-Vaiśeṣika from Gangeśa to Raghunatha Siromani (1993), Ganeri's clearly written book valuably extends our knowledge of the Nyāya philosophy of language by its exposition of the seventeenth-century Nyāya philosopher Gadādhara's Saktivāda or "Essay on Semantic Power." Ganeri's exposition is based on having read the first half of the Saktivāda text with Matilal, before the latter's untimely death, and the second half with Bhattacharyya in Calcutta.In the Saktivāda, Gadādhara defends key Nyāya claims as to how language conveys meaning. In the first half of the text, the author deals with such questions as whether languages are convention-based, whether the central function of language is as an instrument of knowing, whether word meaning or sentence meaning is conceptually prior, and whether the notion of meaning is reducible to physical and/or psychological concepts. In the second half, Gadādhara looks at the semantic problems connected with particular constructions: notably proper and theoretical names, anaphors, indexicals, and the quantifiers. The English exposition of Gadādhara's text offered by Ganeri in this book covers the same topics.According to Gadādhara and the Nyāya philosophy, "the language faculty is a sui generis epistemic faculty, reducible to neither perception nor inference nor some combination of these two. The question for the Naiyāyika is: what properties must the language faculty have if it is in this way to be a source of knowledge?" (p. 15). The Nyāya approach also places an emphasis on testimony as a valid source of knowledge (pramāna), which it understands simply as the transmission by language of knowledge from the speaker to the hearer. The "Communication-intention" variable, discussed by recent thinkers such as McDowell, is not dealt with by Nyāya thinkers, who would deny that the acquisition of knowledge by testimony involves anything like the recognition of the speaker's intentions. Rather, the Nyāya thesis is "that understanding typically consists in direct, non-inferential assent, is in sharp contrast to the assumption implicit in McDowell's position: that assenting to another's utterance is never direct, but always depends on the speaker's intentions, or of the speech-act performed by the speaker" (p. 17). In supporting the Nyāya position, Ganeri appeals to Frege's theory of understanding.The basic idea in the Nyāya philosophy of language is that each of us is endowed with a language faculty, analogous to our perceptual faculty, which generates beliefs from perceived utterances. It has a meaning function. As Ganeri puts it: [End Page 419]My testimonial faculty fixes, as it were, a mapping from utterances of a given language to belief contents. The 'meaning' of a statement for me is, by definition, the belief content to which it is mapped by my testimony faculty. If I am able to understand every statement I hear, the language processing mechanism which underpins this faculty must have a certain compositional structure, and that leads to an assignment of belief-content components to subsequential elements in the language, (p. 29)This thought of Gadādhara, dating from about 1700 C.E., resonates with Chomsky's contemporary ideas of "deep structure" and, in classical Indian philosophy, with Bhartṛhari's fifth-century notion of innate-structuring ideas within consciousness (see Coward and Raja, Encyclopedia of Indian Philosophies, vol. 5). Like Bhartṛhari, Gadādhara takes the sentence to be the irreducible meaning-bearing unit of language.While Karl Potter and Sibajiban Bhattacharyya's volume 6 of The Encyclopedia... (shrink)

I argue that mathematical representations can have heuristic power since their construction can be ampliative. To this end, I examine how a representation introduces elements and properties into the represented object that it does not contain at the beginning of its construction, and how it guides the manipulations of the represented object in ways that restructure its components by gradually adding new pieces of information to produce a hypothesis in order to solve a problem.In addition, I defend an ‘ (...) class='Hi'>inferential’ approach to the heuristic power of representations by arguing that these representations draw on ampliative inferences such as analogies and inductions. In effect, in order to construct a representation, we have to ‘assimilate’ diverse things, and this requires identifying similarities between them. These similarities form the basis for ampliative inferences that gradually build hypotheses to solve a problem.To support my thesis, I analyse two examples. The first one is intra-field, that is, the construction of an algebraic representation of 3-manifolds; the second is inter-fields, that is, the construction of a topological representation of DNA supercoiling.

Language matters to feminism because language is a structure of significances that governs our lives. It contains and conveys the categories through which we understand ourselves and others, and through which we become who and what we are. Our linguistic practices are constituted largely by inferences which in turn constitute or contribute to our understanding of the connections (causal and otherwise) between things. These inferential roles and patterns, which are normatively inscribed, give order and significance to the categories. Once (...) we realize that our linguistic categories reflect and are reflected by our social categories, and once we see that our discursive practices are normative, it is a short step to see language as an arena of political struggle. Feminism is, at the very least, a struggle to end sexist oppression by eradicating both the means by which oppression is carried out and the ideology that seeks that it be carried out. As our most powerful and yet nuanced symbol system, language is perhaps the primary means by which the ideology of sexism is developed and reinforced; it is not news that language is an instrument of oppression. A narrow focus on sexist semantics is of limited use to feminist philosophers, for at best such studies yield lists of past and present harms, with little more to add than “stop it, now.” The real promise of philosophy of language for feminists is an understanding of articulated normativity; by understanding how language really works, we might just understand how the rabbit of normativity gets pulled from the hat of articulation. Language is normative in its production and reproduction of social norms by way of its content, by way of its forms, and most especially by way of its constitutive discursive practices. Once we understand how women are paradoxically constituted by and yet erased from discourse, we may use what we know of these processes of articulation and legitimation to effect and explain our reconstitution as whole.

There is no consensus as to whether a Liar sentence is meaningful or not. Still, a widespread conviction with respect to Liar sentences (and other ungrounded sentences) is that, whether or not they are meaningful, they are useless . The philosophical contribution of this paper is to put this conviction into question. Using the framework of assertoric semantics , which is a semantic valuation method for languages of self-referential truth that has been developed by the author, we show that certain (...) computational problems, called query structures , can be solved more efficiently by an agent who has self-referential resources (amongst which are Liar sentences) than by an agent who has only classical resources; we establish the computational power of self-referential truth . The paper concludes with some thoughts on the implications of the established result for deflationary accounts of truth. (shrink)

Are there illusions of duration? Certainly, many experiences of an event’s duration differ from its measure in clock duration, the measure of that event in seconds, minutes, hours, and so forth. However, I argue that an illusory duration requires more than difference from a real duration; it requires difference from a duration that is relevant to experience. It is plausible to hold that there are many kinds of real duration and reason to question the relevance of all of them. In (...) particular, the interpretation of experienced duration as illusory is typical because it is compared to clock time; the experience of duration goes wrong by being different from a clock measurement of duration. However, I argue that clock duration is not obviously relevant to evaluating the experience of duration.In response, one might hold that it is plausible to evaluate experience by clock duration because clocks more closely match reality than experiences do; on the scale of experience, clock time is no different to real duration. It is not that experienced duration is an illusion because it is merely different from clock duration; it is an illusion because it is different from real duration and we know this because of its difference from clock duration. It is like illusions of size: some object seems to be a size it is not and we know this by comparing it to an object we can otherwise accurately measure by meters.However, unlike size illusions, it is not clear what the ‘real duration’ is against which we should evaluate apparent duration. What is meant by ‘real duration’ involves either an appeal to the duration of substantial absolute time or some kind of duration in things, for example, duration which is the measure of change in some kind of process. is an irrelevant duration; few positions hold that we experience absolute time. As for, if real duration is a measure of change, then, for experienced duration to match clock duration, they must both agree on the relevant change. If there is a difference in what is treated as the real duration, then neither experience nor clocks can be treated as evaluable in terms of the other.Finally, we may have an illusory duration because there are cases of variation between experiences of the same duration. Yet, even here, we may be misled; we may not be directly comparing experiences. We compare the experienced durations through first measuring each in terms of clock duration. If there is a variability in the relationship between clock standard and some relevant standard for experience, then one expects anything accurately meeting one standard to differ from anything accurately meeting the other. The error is holding there is a stable relationship between the standards. This error is not a matter of our experience of duration, and so is not an illusion of duration. (shrink)

ObjectiveTo examine how physical and psychological childbirth experiences affect maternal perceptions and experiences of early infant behavioural style.BackgroundUnnecessary interventions may disturb the normal progression of physiological childbirth and instinctive neonatal behaviours that facilitate mother–infant bonding and breastfeeding. While little is known about how a medicalised birth may influence developing infant temperament, high impact interventions which affect neonatal crying and cortisol levels could have longer term consequences for infant behaviour and functioning.MethodsA retrospective Internet survey was designed to fully explore maternal experiences (...) of childbirth and her postnatal perceptions of infant behaviour. Data collected from 999 mother–infant dyads were analysed using Pearson’s correlations and multiple analyses of covariance, employing the Bonferroni method of correction to establish initially significant variables. Multiple linear regressions were conducted to determine major perinatal contributors to perceived early infant temperament.ResultsMultiple regression analyses on each of the eight Mother and Baby Scales outcome variables indicated that early infant behavioural style was largely predicted by subjective maternal states during and post-childbirth, postnatal depression scores, maternal personality traits and infant age. For example, infant age was the most significant predictor of Alert-Responsive infant behaviour, followed by maternal Postnatal Positive experience. In contrast, depression scores were the most significant predictor of Unsettled-Irregular infant behaviour, followed by Anxious-Afraid Birth Emotions and infant age. Mothers also perceived their infants as more Alert-Responsive and Easier overall after a Supported birth experience.ConclusionMaternal and infant outcomes were influenced by multiple physical and psychological perinatal variables. The mother’s subjective experience appeared to be of equal significance to more objective factors. Social support enhanced the mother’s childbirth experience, benefitting her perceptions of her baby’s early temperament. These findings provide further support for current World Health Organisation intrapartum guidelines on the importance of making childbirth a ‘positive experience’ for women. (shrink)

This book presents an in-depth and critical reconstruction of Prawitz’s epistemic grounding, and discusses it within the broader field of proof-theoretic semantics. The theory of grounds is also provided with a formal framework, through which several relevant results are proved. Investigating Prawitz’s theory of grounds, this work answers one of the most fundamental questions in logic: why and how do some inferences have the epistemic power to compel us to accept their conclusion, if we have accepted their premises? Prawitz (...) proposes an innovative description of inferential acts, as applications of constructive operations on grounds for the premises, yielding a ground for the conclusion. The book is divided into three parts. In the first, the author discusses the reasons that have led Prawitz to abandon his previous semantics of valid arguments and proofs. The second part presents Prawitz’s grounding as found in his ground-theoretic papers. Finally, in the third part, a formal apparatus is developed, consisting of a class of languages whose terms are equipped with denotation functions associating them to operations and grounds, as well as of a class of systems where important properties of the terms can be proved.

This study aims to clarify the role played by higher order dispositions in the context of the explanatory method in Regimen I and of the approach to dietetics in Regimen as a whole.

In bioethics, discussions of justice have tended to focus on questions of fairness in access to health care: is there a right to medical treatment, and how should priorities be set when medical resources are scarce. But health care is only one of many factors that determine the extent to which people live healthy lives, and fairness is not the only consideration in determining whether a health policy is just. In this pathbreaking book, senior bioethicists Powers and Faden confront foundational (...) issues about health and justice. How much inequality in health can a just society tolerate. The audience for the book is scholars and students of bioethics and moral and political philosophy, as well as anyone interested in public health and health policy. (shrink)

Lawrence Kohlberg's Approach to Moral Education presents what the late Lawrence Kohlberg regarded as the definitive statement of his educational theory. Addressing the sociology and social psychology of schooling, the authors propose that school culture become the center of moral education and research. They discuss how schools can develop as just and cohesive communities by involving students in democracy, and they focus on the moral decisions teachers and students face as they democratically resolve problems. As the authors put it: "...we (...) propose an educational renewal of our democratic society.... We have attempted to establish schools that do more than just teach about democratic citizenship, that are themselves democratic societies.". (shrink)

In this article, we address the relevance of J.S. Mill’s political philosophy for a framework of public health ethics. In contrast to some readings of Mill, we reject the view that in the formulation of public policies liberties of all kinds enjoy an equal presumption in their favor. We argue that Mill also rejects this view and discuss the distinction that Mill makes between three kinds of liberty interests: interests that are immune from state interference; interests that enjoy a presumption (...) in favor of liberty; and interests that enjoy no such presumption. We argue that what is of focal importance for Mill in protecting liberty is captured by the essential role that the value of self-determination plays in human well-being. Finally, we make the case for the plausibility of a more complex and nuanced Millian framework for public health ethics that would modify how the balancing of some liberty and public health interests should proceed by taking the thumb off the liberty end of the scale. Mill’s arguments and the legacy of liberalism support certain forms of state interference with marketplace liberties for the sake of public health objectives without any presumption in favor of liberty.

Can computer systems ever be considered moral agents? This paper considers two factors that are explored in the recent philosophical literature. First, there are the important domains in which computers are allowed to act, made possible by their greater functional capacities. Second, there is the claim that these functional capacities appear to embody relevant human abilities, such as autonomy and responsibility. I argue that neither the first (Domain-Function) factor nor the second (Simulacrum) factor gets at the central issue in the (...) case for computer moral agency: whether they can have the kinds of intentional states that cause their decisions and actions. I give an account that builds on traditional action theory and allows us to conceive of computers as genuine moral agents in virtue of their own causally efficacious intentional states. These states can cause harm or benefit to moral patients, but do not depend on computer consciousness or intelligence. (shrink)

As a growing area of research, the philosophy of time is increasingly relevant to different areas of philosophy and even other disciplines. This book describes and evaluates the most important debates in philosophy of time, under several subject areas: metaphysics, epistemology, physics, philosophy of language, philosophy of mind, cognitive science, rationality, and art. -/- Questions this book investigates include: Can we know what time really is? Is time possible, especially given modern physics? Must there be time because we cannot think (...) without it? What do we experience of time? How might philosophy of time be relevant to understanding the mind-body relationship or evidence in cognitive science? Can the philosophy of time help us understand biases toward the future and the fear of death? How is time relevant to art – and is art relevant to philosophical debates about time? Finally, what exactly could time travel be? And could time travel satisfy emotions such as nostalgia and regret? -/- Through asking such questions, and showing how they might be best answered, the book demonstrates the importance philosophy of time has in contemporary thought. Each of the book’s 10 chapters begins with a helpful introduction and ends with study questions and an annotated list of further readings. This and a comprehensive bibliography at the end of the book prepare the reader to go further in their study of the philosophy of time. (shrink)

We seem to directly perceive external things. But can we? According to the time‐lag argument, we cannot. What we directly perceive happens now. There is a time‐lag between our perceptions and the external things we seem to directly perceive; these external things happen in the past; thus, what we directly perceive must be something else, for example, sense‐data, and we can only at best indirectly perceive other things. This paper examines the time‐lag argument given contemporary metaphysics. I argue that this (...) argument is not as compelling as it may initially seem. First, it denies that what we directly perceive can ever be what it seems to be; second, it conflicts with the current physical conception of time, relativity theory. This latter point leads to a more general one: the argument's force depends on a particular metaphysical conception on time, presentism, which is controversial in contemporary metaphysics of time. Given the alternative conception, eternalism, the argument is much less compelling. The overall argument of this paper, then, is that, if one wishes to hold that we directly perceive external things, we should subscribe to the latter view of time, i.e., eternalism. (shrink)

This book features papers from CEPE-IACAP 2015, a joint international conference focused on the philosophy of computing. Inside, readers will discover essays that explore current issues in epistemology, philosophy of mind, logic, and philosophy of science from the lens of computation. Coverage also examines applied issues related to ethical, social, and political interest. -/- The contributors first explore how computation has changed philosophical inquiry. Computers are now capable of joining humans in exploring foundational issues. Thus, we can ponder machine-generated explanation, (...) thought, agency, and other quite fascinating concepts. The papers are also concerned with normative aspects of the computer and information technology revolution. They examine technology-specific analyses of key challenges, from Big Data to autonomous robots to expert systems for infrastructure control and financial services. -/- The virtue of a collection that ranges over philosophical questions, such as this one does, lies in the prospects for a more integrated understanding of issues. These are early days in the partnership between philosophy and information technology. Philosophers and researchers are still sorting out many foundational issues. They will need to deploy all of the tools of philosophy to establish this foundation. This volume admirably showcases those tools in the hands of some excellent scholars. -/- . (shrink)

Historically Wales has been regarded as a country with relatively low levels of school exclusion, particularly in comparison with England. This has been used as an indicator of Wales’ commitment to the UN Convention on the Rights of the Child, which foregrounds a rights-based agenda that would argue school exclusion is a consequence of broader socio-economic structures than individual actions. However, simple analyses may mask a different picture of school exclusions in Wales. In this article, we study more detailed information (...) on formal school exclusions by looking at ‘instances’ of school exclusion, which considers the frequency and length of formal school exclusions in Wales, and alongside recorded school absence. The article also demonstrates that the pupils ‘at risk’ of formal school exclusion varies by when they experience school exclusion during their educational lifecourse. The article concludes by highlighting that patterns of school exclusion are complex, and that interpretation of these patterns depends on what kind of measure of school exclusion is used. By publishing these results, the article hopes to persuade policymakers and practitioners to re-examine their processes of exclusion to ensure they are commensurate with the law and to prevent unnecessary school exclusions.

This paper examines two alleged limitations in the use of formal languages: on the one hand, the trade-offs between expressive and inferential power, and on the other, the phenomenon of system imprisonment. After reconceptualizing the issue, we consider the role played by modality in the understanding of certain aspects of mathematical structures and argue for its centrality.

The doctrine of the specious present, that we perceive or, at least, seem to perceive a period of time is often taken to be an obvious claim about perception. Yet, it also seems just as commonly rejected as being incoherent. In this paper, following a distinction between three conceptions of the specious present, it is argued that the incoherence is due to hidden metaphysical assumptions about perception and time. It is argued that for those who do not hold such assumptions, (...) so long as we are clear about what the doctrine is really saying, we can make perfect sense of the specious present doctrine.

Articles by Lyn Horn and Alison Thompson highlight several points crucial to understanding how our theory figures in wider debates about social justice as well as the particular relevance of our theory for assessing the overall practice of public health (Horn, 2013; Thompson, 2013).
