Constructive empiricism is not just a view regarding the aim of science; it is also a view regarding the epistemological framework in which one should debate the aim of science. This is the focus of this book -- not with scientific truth, but with how one should argue about scientific truth.

There is a natural objection to the epistemic coherence of Bas van Fraassen’s use of a distinction between the observable and unobservable in his constructive empiricism, an objection that has been raised with particular clarity by Alan Musgrave. We outline Musgrave’s objection, and then consider how one might interpret and evaluate van Fraassen’s response. According to the constructive empiricist, observability for us is measured with respect to the epistemic limits of human beings qua measuring devices, limitations ‘which will be described (...) in detail in the final physics and biology’ (van Fraassen 1980: 17). In order for the constructive empiricist to determine what counts as observable, he will have to appeal to our best scientific theories of light, human physiology, and so forth. To put the same point in a slightly more abstract way, in order to draw a distinction between observable and unobservable entities, the constructive empiricist needs to use his best scientific theory of observability – call it T* – to tell him the identity of the observable entities. This raises an interesting difficulty. Constructive empiricism is the view that ‘science aims to give us theories that are empirically adequate; and acceptance of a theory involves as belief only that it is empirically adequate’ (van Fraassen 1980:12). When he accepts a theory, the constructive empiricist only believes the statements of his scientific theories that are about observable entities. Thus, in order to know which statements of a scientific theory to believe, the constructive empiricist needs to know which statements of that theory are about observable entities. In particular then, the constructive empiricist only believes the statements of his theory of observability T* that are about observable entities. Therefore, in order to know which statements of T* he can believe, the constructive empiricist needs to know which statements of T* are about observable entities. However, it is T* that tells the constructive empiricist what counts as an observable entity: the constructive empiricist therefore needs to use T* to tell him which statements of T* he can believe. The fact that the distinction drawn by T* must also apply to itself is not an immediate cause for alarm.. (shrink)

Recent literature in the scientific realism debate has been concerned with a particular species of statistical fallacy concerning base-rates, and the worry that no matter how predictively successful our contemporary scientific theories may be, this will tell us absolutely nothing about the likelihood of their truth if our overall sample space contains enough empirically adequate theories that are nevertheless false. In response, both realists and anti-realists have switched their focus from general arguments concerning the reliability and historical track-records of our (...) scientific methodology, to a series of specific arguments and case-studies concerning our reasons to believe individual scientific theories to be true. Such a development however sits in tension with the usual understanding of the scientific realism debate as offering a second-order assessment of our first-order scientific practices, and threatens to undermine the possibility of a distinctive philosophical debate over the approximate truth of our scientific theories. I illustrate this concern with three recent attempts to offer a more localised understanding of the scientific realism debate—due to Stathis Psillos, Juha Saatsi, and Kyle Stanford—and argue that none of these alternatives offer a satisfactory response to the problem.

James Ladyman ([2000]) argues that constructive empiricism is untenable because it cannot adequately account for modal statements about observability. In this paper, I attempt to resist Ladyman's conclusion, arguing that the constructive empiricist can grant his modal discourse objective, theory-independent truth-conditions, yet without compromising his empiricism.

Constructive empiricism - as formulated by Bas van Fraassen - makes no epistemological claims about the nature of science. Rather, it is a view about the aim of science, to be situated within van Fraassen's broader voluntarist epistemology. Yet while this epistemically minimalist framework may have various advantages in defending the epistemic relevance of constructive empiricism, I show how it also has various disadvantages in maintaining its internal coherence.

In this journal, Peter Lipton and I discussed Musgrave's objection that the constructive empiricist cannot consistently maintain his own distinction between the observable and the unobservable, and van Fraassen's initial reply. We considered several possible interpretations of van Fraassen, and expressed misgivings about each. Muller and van Fraassen have consequently clarified the official constructive empiricist response to Musgrave, although some issues still remain.According to Muller and van Fraassen, Musgrave's objection assumes that constructive empiricism is to be understood in line with (...) a syntactic account of our scientific theories – whereby a theory consists of a set of sentences formulated in some suitable language – whereas constructive empiricism has always been wedded to an explicitly semantic account of our scientific theories, which understands a scientific theory in terms of a class of models. Once this oversight is amended, the objection is seen to be toothless. As Muller and van Fraassen write: " Indeed, the only proper response, and the one that turns the table on Musgrave and his followers, is to argue that his incoherence argument does not work in the context of the semantic view as here elaborated, while the bad consequence he draws is an inevitable corollary to the older view within which he presents it. "The force of Musgrave's objection therefore turns on nothing more than implicitly saddling the constructive empiricist with an independently problematic account of what a scientific theory is.This move should cause some surprise however, for Musgrave's objection – albeit usually presented in conjunction with an explicitly syntactic construal of our scientific theories – is in fact quite neutral between these competing accounts. As Musgrave originally put it, in order for the constructive empiricist to draw his distinction between observable and unobservable …. (shrink)

In this paper, I explore Rosen’s ‘transcendental’ objection to constructive empiricism—the argument that in order to be a constructive empiricist, one must be ontologically committed to just the sort of abstract, mathematical objects constructive empiricism seems committed to denying. In particular, I assess Bueno’s ‘partial structures’ response to Rosen, and argue that such a strategy cannot succeed, on the grounds that it cannot provide an adequate metalogic for our scientific discourse. I conclude by arguing that this result provides some interesting (...) consequences in general for anti-realist programmes in the philosophy of science.Keywords: Constructive empiricism; Mathematical fictionalism; Partial structures; Modality.

Discusses some of the most popular misconceptions about science, and their continuing role in the public imagination. Drawing upon the history and philosophy of science it challenges widespread assumptions and misunderstandings, from creationism and climate change to the use of statistics and computer modeling. The result is an engaging introduction to contentious issues in the philosophy of science and a new way of looking at the role of science in society.

Carnap's mature philosophy of science is an attempt to dissolve the scientific realism debate altogether as a philosophical pseudo-question. His argument depends upon a logico-semantic thesis regarding the structure of a scientific theory, and more importantly, a meta-ontological thesis regarding the explication of existence claims. The latter commits Carnap to a distinction between the analytic and the synthetic, which was allegedly refuted by Quine. The contemporary philosophy of science has therefore sought to distance itself from logico-semantic considerations, and has pursued (...) the scientific realism debate as an essentially epistemological thesis. I show however that one of the most prominent positions in this recent debate—van Fraassen's constructive empiricism—not only ends up in very close proximity to Carnap's attempted dissolution, but even provides the resources for extending and refining his programme. Rather than a historical footnote, Carnap's mature philosophy of science offers a live-option in the current debate. (shrink)

Children ranging from 3 to 5 years were introduced to two anthropomorphic robots that provided them with information about unfamiliar animals. Children treated the robots as interlocutors. They supplied information to the robots and retained what the robots told them. Children also treated the robots as informants from whom they could seek information. Consistent with studies of children's early sensitivity to an interlocutor's non-verbal signals, children were especially attentive and receptive to whichever robot displayed the greater non-verbal contingency. Such selective (...) information seeking is consistent with recent findings showing that although young children learn from others, they are selective with respect to the informants that they question or endorse.

As part of his wider critique of the credibility of miraculous testimony, Hume also offers a rather curious argument as to the mutual detriment of conflicting testimony for the miracles of contrary religious worldviews. Scholarship on this aspect of Hume’s reasoning has debated whether or not the considerations are to be understood as essentially probabilistic, and as to whether or not a probabilistic interpretation of the argument is logically valid. The consensus would appear to offer a positive answer to the (...) first question and a negative answer to the second. In this paper I expose a deeper fallacy in Hume’s reasoning that undermines both probabilistic and non-probabilistic readings. My critique is closely based upon analogous considerations in the philosophy of science, and the equally intriguing issue as to the epistemological relevance of conflicting scientific theories throughout the history of science.

In lieu of an abstract, here is a brief excerpt of the content:A Buddhist CarolPaul M. KeelingI will live in the Past, the Present, and the Future! The Spirits of all Three shall strive within me.—Scrooge on Christmas DayTo the Buddhas of the past, present and all future time... I will prostrate and bow.—ŚāntidēvaCharles Dickens's A Christmas Carol is one of the greatest tales of human redemption known in the Western world. As a child I heard it read aloud every (...) Christmas, and there was always a thrilling magic to rehearing the story of Scrooge's moving spiritual transformation. Yet, the story raises an important spiritual question: Scrooge is a new man on Christmas day, but what about after that? We often vow to be better people and fail. Why is this? A Christmas Carol is, of course, pure fantasy—a deeply heartwarming fantasy that bears repeated hearings—but it nonetheless does raise a real question about how spiritual enlightenment is actually achieved.I still appreciate A Christmas Carol as much as I did when I was a child, but as I have grown older, and after having encountered Buddhist philosophy, I have also begun to contemplate the story of Scrooge's spiritual transformation in a new light. The Buddhist notion of karma entails that, even if we are deeply moved now to change our ways for the better, the unexamined patterns of thought that underpinned our past actions retain a latent force in our mind stream that can influence us unexpectedly. If we are not observant of these patterns of thought, we are likely to repeat the kinds of actions we have performed in the past. Because the force of karma can be very strong, "overnight" spiritual and moral transformations are comparatively rare. On a Buddhist reading, the end of A Christmas Carol is where the spiritual journey for Scrooge actually begins.This underestimation of the force of karma on Dickens's part was, of course, a necessary case of artistic license, but is somewhat conspicuous given that a realization of the law of karma plays a critical (albeit unnamed) role in the story of Scrooge's putative enlightenment. Scrooge's transformation begins with a visit from the ghost [End Page 25] of his deceased business partner, Jacob Marley, a man who was as miserly and selfish as Scrooge himself. Marley's ghost is weighed down by a heavy chain, which represents his regret for having lived such a greedy and shortsighted life. "I wear the chain I forged in life. I made it link by link, yard by yard: I girded it on my own free will, and of my own free will I wore it."1 He warns that Scrooge will be visited by three spirits whose lessons he must heed in order to redeem himself. "Without their visits," Marley declares, "you cannot hope to shun the path I tread."2 Upon Marley's departure we are then treated to a Dickensian image of the Buddhist "lower realms." Scrooge looks out the window into the cold night air and sees a swarm of unfortunate ghostly forms, suffering and encumbered by heavy chains of remorse: "The air was filled with phantoms, wandering hither and thither in restless haste, and moaning as they went.... The misery with them all was, clearly, that they sought to interfere, for good, in human matters, and had lost this power for ever."3 Later, Scrooge's nephew Fred makes this pithy karmic observation: "Scrooge's offences carry their own punishment.... Who suffers by his ill whims? Himself, always."4Throughout the remainder of the night Scrooge is visited sequentially by the three spirits representing the Christmases past, present, and future, who, like helpful bodhisattvas, show him scenes from his life in order to awaken him to a realization of the law of karma. By the Ghost of Christmas Past Scrooge is presented with painful images of his childhood suffering as well as the kindness shown to him by others in the past, and learns how the present direction of his life has been shaped by these experiences. The Ghost of Christmas Present reminds Scrooge of the precious opportunities all around him to do good by his fellow... (shrink)

Bernard Dickens seeks to undermine the legal and ethical protections accorded to health care workers and hospitals conscientiously objecting to abortion. First, he appeals to the rationale of antidiscrimination laws as a basis for arguing against conscientious objection. Second, he argues that conscientious objection undermines the rights of patients and their autonomy. Third, he holds that conscientiously objecting doctors have a duty to refer patients for abortion. Fourth, he believes that Kant’s principle of respect for humanity as an end in (...) itself is violated by conscientious objection to abortion. Fifth, Dickens quotes remarks by Pope John Paul II as support for the idea that physicians should not conscientiously object to abortion. Finally, he posits that institutions, such as Catholic hospitals, have a responsibility to provide abortions. I argue that all of the arguments offered by Dickens against conscientious objection are unsound. (shrink)

Public health aims to provide universal safety and progressive opportunities to populations to realise their highest level of health through prevention of disease, its progression or transmission. Screening asymptomatic individuals to detect early unapparent conditions is an important public health intervention strategy. It may be designed to be compulsory or voluntary depending on the epidemiological characteristics of the disease. Integrated screening, including for both syphilis and cancer of the cervix, is a core component of the national reproductive health program in (...) Kenya. Screening for syphilis is compulsory while it is voluntary for cervical cancer. Participants’ perspectives of either form of screening approach provide the necessary contextual information that clarifies mundane community concerns. (shrink)

Descartes is widely portrayed as the arch proponent of “the epistemological transparency of thought” (or simply, “Transparency”). The most promising version of this view—Transparency-through-Introspection—says that introspecting (i.e., inwardly attending to) a thought guarantees certain knowledge of that thought. But Descartes rejects this view and provides numerous counterexamples to it. I argue that, instead, Descartes’s theory of self-knowledge is just an application of his general theory of knowledge. According to his general theory, certain knowledge is acquired only through clear and distinct (...) intellection. Thus, in his view, certain knowledge of one’s thoughts is acquired only through clear and distinct intellection of one’s thoughts. Introspection is a form of intellection and it can be clear and distinct. Ordinarily, however, introspection isn’t clear and distinct but is instead confused with dubitable perceptions of bodies. To make introspection clear and distinct, we need to “sharply separate” it from all perceptions of bodies by doubting all perceptions of bodies. Without such radical doubt, introspection remains confused and we lack certain knowledge not just of the specific features of our thoughts, but even of the minimal claim that a thought exists. Far from being the high priest of Transparency, Descartes is radically opposed to it. (shrink)

Prohibition on sex selection may well be unnecessary and oppressive as well as posing risks to women’s lives The urge to select children’s sex is not new. The Babylonian Talmud, a Jewish text completed towards the end of the fifth century of the Christian era, advises couples on means to favour the birth of either a male or a female child.1 The development of amniocentesis alerted the public in the mid-1970s to the scientific potential for prenatal determination of fetal sex,2 (...) and progressive decriminalisation of abortion afforded choice about continuation of pregnancy. The more recent emergence of preimplantation genetic diagnosis (PGD) obviates resort to abortion, and improved techniques of sperm sorting and diagnosis permit creation of zygotes that will ensure the sex of a future child. Growth of biomedical means to select the sex of future children has been accompanied by fear that such means will be employed to favour births of sons, and so perpetuate devaluation of girl children and women’s inferior family and social status. A reaction to this fear has been the demand for legal and medical professional prohibition of sex selection techniques. For instance, the Council of Europe’s Convention on Human Rights and Biomedicine3 provides in article 14 that: The use of techniques of medically assisted procreation shall not be allowed for the purpose of choosing a future child’s sex, except where serious hereditary sex-related disease is to be avoided. Legislation has been enacted in a number of countries, and proposed in others, to prohibit sex selection on non-medical grounds, such as the Prenatal Diagnostic Techniques (Regulation and Prevention of Misuse) Act, 1994 in India. In Canada, for instance, government draft legislation introduced in May 2002 proposes to make it a crime for any person, for the purpose of creating a human …. (shrink)

The options in a decision problem generally have outcomes with common features. Putting aside the common features simplifies deliberations, but the simplification requires a philosophical justification that this book provides.

The first book-length study of a leading tenth-century Ismaili theoretician Abu Ya'qub al-Sijistani.

I contend that Jews, Christians, and Muslims who seek peace should not be reluctant to acknowledge the existence of their sometimes profound disagreements, or to affirm the truth of their own beliefs and practices. Since this places me at odds with John Hick, I analyze his views, granting the strengths of his critical realism and arguing that his revisionist-pluralist theory of religion has significant limitations for interreligious dialogue. Since the veridical-pluralist alternative I propose facilitates rather than stifles disagreement, I examine (...) three different conceptions of dialogue that acknowledge the importance of disputes among those searching for truth. I also discuss three virtues--honesty, empathy, and humility--whose cultivation would make us less likely to fail in our search for truth and the peace that is its sign and fruit. (shrink)

The centrality of death rituals has in anthropologically informed studies of Buddhism been little documented. The current volume brings together a range of perspectives on Buddhist death rituals including ethnographic, textual, historical and theoretically informed accounts, and presents the diversity of the Buddhist funeral cultures of mainland Southeast Asia and China. It arises out of the University of Bristol's Centre for Buddhist Studies research project Buddhist Death Rituals in Southeast Asia and China, funded by the United Kingdom's Arts and Humanities (...) Research Council. This project involved extensive new research in Thailand, Laos and China. Other items from that project included several public exhibitions, extensive stills photographs, and several video films. The project-team produced two 30 minutes films on the ghost festival in Laos and China, one on urban funerals in Chiang Mai (Thailand) and several shorter clips dealing with funeral cultures in Laos, Thailand and China. Most of this material (and an extensive bibliography on the topic) is available free of charge from the project website located at the webpage of the Department of Theology and Religious Studies (Centre for Buddhist Studies) at the University of Bristol.

This article contends that the evolution toward interdisciplinary collaboration that we are witnessing in the sciences must also occur in the humanities to ensure their very survival. That is, humanists must be open to working with scientists and social scientists interested in similar research questions and vice versa. Digital humanities is a positive first step. Complexity science should be the next step. Even though much of the ground-breaking work in complexity science has been done in the natural sciences and mathematics, (...) it can, if critically adapted, provide the needed metaphor for a broad integration of disciplines, humanistic and otherwise. Given its almost a-disciplinary nature, a complexity approach to the research problems in the humanities necessarily breaks down silos. Moreover, it can restore and reframe the seamless intellectual fabric sought by researchers before the atomization of the various disciplines in the nineteenthcentury academy. (shrink)

An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation of (...) an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement. (shrink)

Schelling und Hegel benutzen in ihren philosophischen Texten mathematische und naturwissenschaftliche Modelle wie Unendlichkeit oder Gleichgewicht. Die Strukturen dieser Begriffe liefern einen Massstab fur den Vergleich der Positionen Schellings und Hegels, der fur Schellings Identitatsphilosophie und Hegels erste Jenaer Schriften durchgefuhrt wird. Als wichtigstes Resultat kann eine grundlegende Differenz zwischen beiden Positionen bereits um 1801 nachgewiesen und gezeigt werden, dass diese auf einer unterschiedlichen Auffassung der Rolle des Absoluten beruht.

This article studies the proposal of the twentieth-century anticaste scholar and writer Iyothee Thass of a millennial anticaste communitas (community) in creative opposition to caste immunitas (immunity). It argues that Thass’s casteless community makes an appeal as it withdraws from caste and Brahminism by differentiating itself from enclosure. Thass’s works sought to conceive and construct a community against caste in the vernacular both in the global and local context by way of a highly scholarly as well as creative engagement with (...) Buddhism and the Tamil literary archive. In the colonial and nationalist context of the nineteenth century in the Indian subcontinent, his interpretative imaginaire of the history of India—Indhira Dhesa Sarithiram—was a pedagogy that establishes a belonging to world community and, at the same time, to one’s own vernacular communities.

Like Plato, Protagoras held that young children learn virtue from fine examples in poetry. Unlike Plato, Protagoras taught adults by correcting the diction of poets. In this paper I ask what his standard of correctness might be, and what benefit he intended his students to take from exercises in correction. If his standard of correctness is truth, then he may intend his students to learn by questioning the content of poems; that would be suggestive of Plato’s program in Republic III. (...) But his standard is more likely to be the accurate use of language; in that case he would intend his students to learn to express their thoughts clearly enough that their audience would understand what they were saying. That standard would be independent of the truth of what they are saying; and that would be a precursor to modern techniques by which we try to teach speaking and writing. Truth is not so easy to escape, however, and we shall see that Protagoras’ exercise must assume that the poet is trying to tell the truth. (shrink)
