It is sometimes argued that mathematical knowledge must be a priori, since mathematical truths are necessary, and experience tells us only what is true, not what must be true. This argument can be undermined either by showing that experience can yield knowledge of the necessity of some truths, or by arguing that mathematical theorems are contingent. Recent work by Albert Casullo and Timothy Williamson argues (or can be used to argue) the first of these lines; W. V. Quine and (...) Hartry Field take the latter line. I defend a version of the argument against these, and other objections. (shrink)

'Knowledge and its Limits' starts its exposition of the knowledge-first approach to epistemology with a structural analogy between knowledge and action as the two key relations between mind and world (Williamson 2000: 1, 6-8). This chapter aims to reconsider the relation between knowledge and action, and refine the analogy.

In Fixing Language, Herman Cappelen defends the project of conceptual engineering from a family of objections that he calls “the Strawsonian challenges.” Those objections are all versions of this: “If I ask you a question about the F’s, and you give me an answer that’s not about the F’s but rather about the G’s, then you haven’t answered my question. You have changed the subject.” I argue that Cappelen’s response succeeds in reply to one understanding of the Strawsonian challenge—on which (...) it is motivated by ordinary judgments of samesaying and continuity of topic—but that it fails as a response to another version—on which a parallel objection is motivated by philosophical considerations and is stated in a theoretical register.

When Timothy Sprigge's The Vindication of Absolute Idealism appeared in 1983 it ran very much against the grain of the dominant linguistic and analytic traditions of philosophy in Britain. The very title of this work was a challenge to those who believed that Absolute Idealism fell with the critiques of Bertrand Russell and G. E. Moore at the beginning of the 20th century. Sprigge, however, saw himself as providing an underrepresented position in the philosophical spectrum rather than as advocating (...) an abandoned view. For him, idealism did not fall at any determinate point in the history of philosophy. The truth of any philosophical thesis cannot depend on what happens to be currently fashionable, but rather must stand on the soundness of philosophical argument. To this end, The Vindication of Absolute Idealism is a bold statement of his conclusions, a synthesis of panpsychism and absolute idealism, which he contends is the most satisfactory solution to the question of the nature of consciousness and the mind-body problem. Sprigge's view of consciousness remains a challenge to mainstream physicalism and a viable option that addresses pressing contemporary concerns not only in metaphysics and philosophy of mind but also in environmental ethics and animal rights.

Despite several decades of criticism, dichotomous thinking about behavioral development remains widespread and influential. This is particularly true in study of birdsong development, where it has become increasingly common to diagnose songs, elements of songs, or precursors of songs as either innate or learned on the basis of isolation-rearing experiments. The theory of sensory templates has encouraged both the dichotomous approach and an emphasis on structural rather than functional aspects of song development. As a result, potentially important lines of investigation (...) have been overlooked and the interpretation of existing data is often flawed. Evidence for a genetic origin of behavioraldifferencesis frequently interpreted as evidence for the genetic determination of behavioralcharacters. The technique of isolation rearing remains the methodology of choice for many investigators, despite the fact that it offers only a rather crude analysis of the contribution of experience to song development and provides no information at all about genetic contributions to development. The latter could in principle be elucidated by the application of developmental-genetic techniques, but it is unlikely that these can easily be applied to the study of birdsong. Because developmental questions are so often posed in terms of the learned–innate dichotomy, “experience” is taken to be synonymous with “learning” and the possible role of nonobvious contributions to song development has largely been ignored. An alternative approach, based on Daniel Lehrman's interactionist theory of development, permits a more thorough appreciation of the problems that have yet to be addressed, and provides a more secure conceptual foundation for theories of song development.

This paper discusses the nature and the status of inference to the best explanation. We outline the foundational role given IBE by its defenders and the arguments of critics who deny it any place at all ; argue that, on the two main conceptions of explanation, IBE cannot be a foundational inference rule ; sketch an account of IBE that makes it contextual and dependent on substantive empirical assumptions, much as simplicity seems to be ; show how that account avoids (...) the critics ' complaints and leaves IBE an important role ; and sketch how our account can clarify debates over IBE in arguments for scientific realism.

This chapter aims to attempt no more than to make some informal and unsystematic remarks on the transformation of analytic philosophy. It deals with a few sketchy remarks on the historiography of recent analytic philosophy. Writing in 1981, David Lewis described “a reasonable goal for a philosopher” as bringing one’s opinions into stable equilibrium. A natural comparison is between Lewis’s Quinean or at least post‐Quinean methodology and the methodology of Peter Strawson, Quine’s leading opponent from the tradition of ordinary language (...) philosophy. Analytic epistemology provides a good case study of the philosophical application of Gricean pragmatics outside the philosophy of language. On Michael Dummett picture of the history of philosophy, Descartes had made epistemology first philosophy, the engine for the rest of philosophy, and then Frege had replaced epistemology by the philosophy of language as first philosophy. The chapter suggests that philosophy sometimes already uses an abductive methodology and ought to use it more in the future. (shrink)

According to Gamper, one function of science is to determine how the world is. Science, Gamper continues, rests on a set of basic assumptions, and the gap between basic assumptions and science should be filled by ontological frameworks that accommodates the modal properties of such assumptions. Different frameworks may surely suggest different modal properties. Thus, in so far as we use different basic assumptions, we can have different ontologies with different modal properties. Ontologies affect, in turn, science, which, however, has (...) the power to falsify the ontological frameworks. The aim of this article is to show a possible trouble of Gamper's proposal, here considered as applied to the geographical debate. (shrink)

Internalism and Epistemology is a powerful articulation and defense of a classical answer to an enduring question: What is the nature of rational belief? In opposition to prevailing philosophical fashion, the book argues that epistemic externalism leads, not just to skepticism, but to epistemic nihilism - the denial of the very possibility of justification. And it defends a subtle and sophisticated internalism against criticisms that have widely but mistakenly been thought to be decisive. Beginning with an internalist response to the (...) Gettier problem, the authors deal with the problem of the connection to truth, stressing the distinction between success and rationality as critical to its resolution. They develop a metaregress argument against externalism that has devastating consequences for any view according to which epistemic principles are contingent. The same argument does not, they argue, affect the version of internalism they espouse, since its epistemic principles are analytic and knowable a priori. The final chapter addresses the problem of induction and shows that its solution turns critically on the distinction between success and rationality - the very distinction that lies at the heart of the dispute between internalists and externalists. Provocative, probing, and deliberately unfashionable, Internalism and Epistemology is a ringing defense of internalism that will interest specialists and students alike. It is essential reading for anyone who suspects that rumors of the death of traditional epistemology have been greatly exaggerated. (shrink)

Despite the fact that information systems ontologies [ISOs] support the mutual understanding between human beings and software applications, human beings and software applications do not understand ISOs' contents in the same way. The same applies to ontological integration. This paper attempts to account for such discrepancies by emphasizing that while human being can have access to entities represented in ISOs, software applications cannot.

Nudging is a tool of libertarian paternalism. It involves making use of certain psychological tendencies in order to help people make better decisions without restricting their freedom. However, some have argued that nudging is objectionable because it interferes with, or undermines, the rational decision-making of the nudged agents. Opinions differ on why this is objectionable, but the underlying concerns appear to begin with nudging’s threat to rational decision-making. Those who discuss this issue do not make it clear to what this (...) threat to rationality amounts. In this paper I evaluate what effect nudging has on our decision-making and I argue that it does not typically interfere with our rationality in a problematic way. Perhaps nudging is objectionable for other reasons, but we should not argue that nudging is objectionable based on concerns about rational decision-making. (shrink)

In the few years since the advent of ‘Big Data’ research, social media analytics has begun to accumulate studies drawing on social media as a resource and tool for research work. Yet, there has been relatively little attention paid to the development of methodologies for handling this kind of data. The few works that exist in this area often reflect upon the implications of ‘grand’ social science methodological concepts for new social media research. By contrast, we advance an abductively oriented (...) methodological suite designed to explore the construction of phenomena played out through social media. To do this, we use a software tool – Chorus – to illustrate a visual analytic approach to data. Informed by visual analytic principles, we posit a two-by-two methodological model of social media analytics, combining two data collection strategies with two analytic modes. We go on to demonstrate each of these four approaches ‘in action’, to help clarify how and why they might be used to address various research questions. (shrink)

In his early discussion of the structure of matter and motion, Leibniz quite explicitly appeals to Aristotle's characterization of continuity, and seems to adopt something like it as his own. Commentators usually assume that Leibniz continues to understand the notion of continuity in this way for the rest of his life. This paper argues that although he does continue to use something like the Aristotelian conception well into the mature period of his thought, he articulates a second sense of continuity (...) in his later writings that proves to be a greater importance to the exposition of his mature metaphysics.

Many philosophers believe that true belief is of epistemic value, but that knowledge is of even more epistemic value. Some claim that this surplus value is instrumentally valuable to the value of true belief. I call the conjunction of these claims the Instrumentalist’s Conjunction. The so-called “Swamping Problem” is meant to show that Instrumentalist’s Conjunction is inconsistent. Crudely put, the problem is that if knowledge only has surplus value to the value of true belief, and a belief is true because (...) known, then knowledge cannot be of any more value than true belief. Given the inconsistency, most philosopher reject the claim the surplus value of knowledge is instrumental to the value of true belief. This paper argues that the Swamping Problem is illusory. Once we clean up the problem and pay attention to the distinction between token/type properties, we can see that Instrumentalist’s Conjunction is perfectly coherent. (shrink)

Aristotle's use of the phrase τὰ καλούμενα στοιχεȋα is usually taken as evidence that he does not really think that the things to which this phrase refers, namely, fire, air, water, and earth, are genuine elements. In this paper I question the linguistic and textual grounds for taking the phrase τὰ καλούμενα στοιχεȋα in this way. I offer a detailed examination of the significance of the phrase, and in particular I compare Aristotle's general use of the Greek participle καλούμενος (-η, (...) -ον) in other contexts. I conclude that his use of the phrase τὰ καλούμενα στοιχεȋα does not carry ironical or sceptical connotations, and that it ought to be understood as a neutral report of a contemporary opinion that the elements of bodies are fire, air, water, and earth. I leave aside the question as to whether or not Aristotle himself endorses this opinion. (shrink)

The brain requires sustained interaction with a rich physical and social environment to stay healthy. Individuals without access to such enabling environments and who instead live and grow in disabling environments tend to have greater risk of developing dementia. But research and policymaking as regards dementia risk reduction have so far focused almost exclusively on the role of how individuals’ health behaviors change their risk profile. This exclusive focus on “lifestyle” is both ethically problematic and therapeutically inadequate. I highlight a (...) growing literature on three different kinds of deprivation, an independent and overlooked risk factor for dementia that invites upstream action against inequalities. Future prevention guidelines should include explicit mention of deprivation as a risk factor and be developed around the need to make society fairer. Meanwhile, interventions and discourse based on lifestyle modification should respect the principle of “no ought without support.”. (shrink)

The role education plays in society has been contested in the United States since the inception of public education. Historically this contention has produced a delicate balance between promoting the social justice concerns of educating democratic citizens and the disciplinary concerns of individual intellectual development. Teacher preparation programs in American normal schools, colleges, and universities have traditionally struck a similar balance between theory and practice. In the past several decades, however, the rise of neoliberalism in American politics has shifted the (...) balance away from equity, diversity, and inclusivity. The purpose of this study is to provide an account of the lived experiences of teacher candidates with the phenomena of being and becoming “woke” within a teacher education program that reflects neoliberal values but maintains a stated commitment to social justice. This study includes narrative vignettes that explore the phenomenality of “wokeness” as it manifests in the public-school environment and the teacher education program. It also addresses the effects of neoliberalism on teacher candidates’ willingness and ability to take up social justice for themselves, their students, and society. (shrink)

The article is an outline of some of the key thoughts of two Dutch Calvinist philosophers who have had a major impact on sections of modern evangelicalism. These key thoughts are sphere sovereignty, closely associated with Kuyper but adopted enthusiastically by Dooyeweerd as well, and modal aspects, which is particularly associated with Dooyeweerd. The impact of these key thoughts on how we should view social structures is given, focusing particularly on the state, the church, the family and marriage, and the (...) university. There is one key reservation about this line of thinking, held because so prevalent among in the Neo-Calvinist circles so inspired by Kuyper and Dooyeweerd, that of pillarisation. It is argued briefly here, effectively as a postscript, that this represents a line of thinking that does not belong to sphere sovereignty or to modal aspects. (shrink)

At first glance, it seems difficult to object to any program that merits the label “harm reduction.” If harm is bad, as everyone recognizes, then surely reducing it is good. What’s the problem? The problem, we submit, is twofold. First, there’s more to “harm reduction,” as that term is typically used, than simply the reduction of harm. Some of the wariness about harm-reduction programs may result from the nebulous “more.” Thus, part of our task is to provide a clear definition (...) of harm reduction. Next, we turn to a second problem: a worry about complicity. Those who object to harm reduction programs fear that participation in such programs would make them complicit in activities they deem immoral. In this paper we argue that this fear is largely unwarranted. We use supervised injection sites —safe spaces for the use of risky drugs—as our paradigmatic case of harm reduction. These SISs are generally offered in the hope of reducing harm to both the drug user and the public. For this reason, our analysis focuses on complicity in harm. We draw upon the work of Gregory Mellema as our framework. Mellema offers three ways one can be complicit in harm caused by another: by enabling, facilitating or condoning it. We argue that one who operates an SIS is not complicit in any of these ways, while also laying out the conditions that must be met if one is to argue that harm reduction entails complicity in non-consequentialist wrongdoing.

Existing research suggests that men and women have similar reasons for attending North American seminaries and are influenced strongly by faculty while in school. To increase understanding of the experiences of women and men in seminary, this study used interactive qualitative analysis to discover and compare the main themes of seminary experience for men and women at one Protestant seminary. Study results show men and women differed in their perception of how seminary influenced their sense of calling. One third of (...) women interviewed reported experiences of resistance to their pursuit of ministry as a vocation. Further research is needed to explore the mechanisms that continue to reproduce sexism. The author argues that seminaries need to increase the proportion of women faculty members to promote the flourishing of all students. (shrink)

This paper addresses religious epistemology in that it concerns the assessment of the credibility of certain claims arising out of religious experience. Developments this century have made the world’s rich religious heritage accessible to more people than ever. But the conflicting religious claims tend to undermine each religion’s central claim to be a vehicle for opening persons to ultimate reality. One attempt to overcome this problem is provided by "perennial philosophy," which claims that there is a kind of mystical experience (...) common to all religious traditions, an experience which is an immediate contact with an absolute principle. Perennialism has been attacked by "contextualists" such as Steven Katz who argue that particular mystical experiences are so tied to a particular tradition that there are no common mystical experiences across traditions. In turn, Robert Forman and the "decontextualists" have argued that a certain kind of mystical experience and process are found in diverse traditions, thereby supporting one of the key elements of perennialism. I review the contextualist-decontextualist debate and suggest a research project that would pursue the question of whether the common ground of the world’s mystical traditions could be expanded beyond what has been established by the decontextualists. The extension of this common ground would add credibility to the claims arising out of mystical experience. (shrink)

In this global introduction to philosophy of religion you begin not with a single tradition, but with religious philosophies from East Asia, South Asia, West Africa, and Native North America, alongside the classical Abrahamic and modern European traditions. Matching this diversity of traditions, chapters are organized around questions that acknowledge there is no single understanding of any god or ultimate reality. Instead you approach six different traditions of philosophizing about religion by asking questions about the journeys of both the self (...) and the cosmos such as "What is my path?" and "Where did the cosmos come from?" Accompanied by introductory materials and an extensive glossary, each chapter includes learning objectives, questions for discussion, and suggested primary and secondary sources. The categories of religion and philosophy are interrogated throughout. Equipped with study tools and universal questions about the self and the cosmos, Philosophies of Religion: A Global and Critical Introduction shows you how to philosophize about religions around the world.

In recent years philosophers have attempted to clarify the units of selection controversy in evolutionary biology by offering conceptual analyses of the term 'unit of selection'. A common feature of many of these analyses is an emphasis on the claim that units of selection are entities exhibiting heritable variation in fitness. In this paper I argue that the demand that units of selection be characterized in terms of heritability is unnecessary, as well as undesirable, on historical, theoretical, and philosophical grounds. (...) I propose a positive account of the proper referent of the term 'unit of selection', distinguishing between the processes of evolution and phenotypic selection. The main result of this analysis is greater clarity about the conceptual structure of evolutionary theory. (shrink)

In moral psychology, it has long been argued that empathy is a necessary capacity of both properly developing moral agents and developed moral agency . This view stands in tension with the belief that some individuals diagnosed with autism—which is typically characterized as a deficiency in social reciprocity —are moral agents. In this paper we propose to explore this tension and perhaps trouble how we commonly see those with autism. To make this task manageable, we will consider whether high functioning (...) individuals diagnosed with an autism spectrum disorder are capable of empathetic responses. If they are, then they possess a capacity that, on the view above, is required for moral agency. If they are not so capable, and yet sometimes engage in moral behaviour, this casts some doubt on the claim that empathy is required for moral agency. This second possibility will necessitate an exploration of the capacity of some individuals with autism to engage in moral behaviour, giving us further grounds to re-see these individuals as moral agents.

Let us sum up. We began with the question, “What is the interest of a model-theoretic definition of validity?” Model theoretic validity consists in truth under all reinterpretations of non-logical constants. In this paper, we have described for each necessity concept a corresponding modal invariance property. Exemplification of that property by the logical constants of a language leads to an explanation of the necessity, in the corresponding sense, of its valid sentences. I have fixed upon the epistemic modalities in characterizing (...) the logical constants: to be a logical constant in the language of a population is to be invariant over a modality describing complete possible epistemic states of that population (or an idealized analogue thereof). The grounds for this characterization are these: (1) It leads, I believe, to an extensionally reasonable demarcation of the logical constants, including clear cases and excluding clear non-cases. It gives a principled criterion for deciding unclear cases. (2) It provides an analysis of the topic-neutrality of logic. (3) It leads to an explanation of the epistemic necessity of the logical truths in terms of the topic-neutrality of the logical constants.All the same, it is reasonable to ask, even if the suggested demarcation of logic is extensionally correct, whether it can reasonably be expected to be fundamental. The epistemic invariance of an expression is a rather striking property, one which we should want to explain. What is missing, then, is an explanation of the distinguishing epistemic properties of the constants in terms of more fundamental properties involving their understanding and use. It would be these that properly define the nature, not just the extent, of logic. (shrink)

In this chapter, we begin with a discussion of motivation itself, and use that discussion to sketch four possible theories of distinctively moral motivation: caricature versions of familiar instrumentalist, cognitivist, sentimentalist, and personalist theories about morally worthy motivation. To test these theories, we turn to a wealth of scientific, particularly neuroscientific, evidence. Our conclusions are that (1) although the scientific evidence does not at present mandate a unique philosophical conclusion, it does present formidable obstacles to a number of popular philosophical (...) approaches, and (2) theories of morally worthy motivation that best fit the current scientific picture are ones that owe much more to Hume or Aristotle than to Kant.

The author argues that philosophers' attempts to use philosophy of language to solve problems of jurisprudence have often failed- the most dramatic failure being that of Jeremy Bentham. H.L.A.Hart made some related mistakes in his creative use of philosophy of language, yet his focus on language still yields some very significant insights for jurisprudence: the context principle (that the correct application of linguistic expressions typically depends on context in ways that are important for jurisprudence), the diversity principle (that grounds of (...) correct application of legal language may be diverse), and the importance of vagueness.

Untying the Gordian Knot shows how the fundamental notions of process, logic and relations, woven with triads of input-output-context, can be combined with quantum distinctions associated with actuality and potentiality, enabling the leveraging of many advances in philosophy and physics to unravel several long-standing philosophical problems.

The comparative method, closely identified with Darwinian evolutionary biology, also has a long pre-Darwinian history. The method derives its scientific power from its ability to interpret comparative observations with reference to a theory of relatedness among the entities being compared. Such scientifically powerful strong comparison is distinguished from weak comparison, which lacks such theoretical grounding. This paper examines the history of the strong comparison permitted by the comparative method from the early modern period to the threshold of the Darwinian revolution (...) in the mid nineteenth century. It interprets the work of early pioneers such as Belon, Willis, Perrault, and Tyson from this methodological perspective, rather than focusing on their particular anatomical findings. Although these early writers made formative scientific contributions through their comparative investigations, the more theoretically grounded application of the comparative method by Geoffroy, Cuvier, and Owen was instrumental in laying the foundation for its later incorporation into Darwinian evolutionary theory.

This chapter introduces readers to the aims and scope of the book. Readers are given the social and scholarly context in which the book emerges. The introduction suggests that the history and philosophy of hospice care contain moral values that can be resonant or dissonant with larger social values, giving those who work in hospice organizations an important place in the national discussion about terminal care. Finally, it offers a brief explanation of the goals of each chapter in the book.

Widespread, deep controversy as to the content of the law of a community is compatible with the view that the law is a system of rules. I defend that view through a critique of Ronald Dworkin's discussion of Riggs v. Palmer 22 N.E. 188. Dworkin raised an important challenge for jurisprudence: to account for the fact that legal rights and duties are frequently controversial. I offer an explanation of the possibility of deep disagreement about the application of social rules, which (...) reconciles controversy as to the content of the law, with the model of a legal system as a system of rules. And I discuss the implications for understanding the role of judicial discretion in law. (shrink)

The notion of accountability was introduced by Harold Garfinkel in the opening pages of Studies in Ethnomethodology as part of his ‘central recommendation’ for sociological inquiry. Though the term itself first appears in the Studies, it will be argued that elements of the idea were already discernible in earlier writings. The current article traces the development of the notion from its early emergence in the proto-ethnomethodological period, through its elaboration in the Studies, and, finally, to its refinement in certain later (...) works produced toward the end of the author’s career. In so doing, it reveals the centrality of the notion to ethnomethodologically-informed study and shows its enduring contribution to social theory. (shrink)

In an important article, Kim Sterelny and Philip Kitcher challenge the common assumption that for any biological phenomenon requiring a selectionist explanation, it is possible to identify a uniquely correct account of the relevant selection process. They argue that selection events can be modeled in any of a number of different, equally correct ways. They call their view ' Pluralism,' and explicitly connect it with various antirealist positions in the philosophy of science. I critically evaluate Sterelny and Kitcher's Pluralism along (...) with its attendant antirealist theses. In particular, I argue that there are serious problems with their pluralistic antirealism regarding units of selection. By correctly diagnosing these problems a more adequate position can be constructed. I defend such a position, which I designate Inclusive Hierarchical Monism, and show how it captures the important virtues of Sterelny and Kitcher's approach while avoiding its problems. (shrink)

Ethical issues surrounding the marketing and trade of controversial products such as tobacco require a better understanding. Virginia Slims, an exclusively women’s cigarette brand first launched in 1968 in the USA, was introduced during the mid 1980s to major Asian markets, such as Japan and Korea, dominated by male smokers. By reviewing internal corporate documents, made public from litigation, we examine the marketing strategies used by Philip Morris as they entered new markets such as Japan and Korea and consider the (...) extent that the company attempted to appeal to women in markets where comparatively few women were smokers. The case study of Virginia Slims reveals that the classification of “vulnerable” consumers is variable depending on culture, tobacco firms display responsive efforts and strategies when operating within a “mature” market, and cultural values played a role in informing Philip Morris’ strategic decision to embrace an adaptive marketing approach, particularly when entering the Korean market. Finally, moral questions are raised with tobacco being identified as a priority product for export and international trade agreements being used by corporations, governments, or trade partners in efforts to undermine domestic public health policies.

For half a century the idea of rational thought has been challenged by discoveries that call into question some of its foundations. How we actually think seems to be at odds with descriptive and prescriptive models that once held sway in the development of modern science and scholarship. One response to these challenges has been a loss of nerve. Another—the one on display in Rationality: Contexts and Constraints—is an active attempt to revise those models, so as to enhance their compatibility (...) with new discoveries, in a maximally coherent and inclusive way. Rationality: Contexts and Constraints is an inter-disciplinary reappraisal of the nature of rationality. In method it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between hoary scholarship and cutting-edge philosophical or scientific research. In this way, Rationality: Contexts and Constraints contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. • Addresses recent challenges and Identifies a direction for future research on rationality • Investigates the relationship between rationality and mental disorders such as delusion and depression • Assesses reasoning in artificial intelligence and nonhuman animals • Reflects on ancient Chinese Philosophy and possible cultural differences in human psychology • Employs philosophical reflection along with linguistic, probabilistic, and logical techniques -/- .
