The call for papers for this conference claims that 'the founders of modern philosophy of science, including Sir Karl Popper… saw it as part of their role to explain the authority of science’. It continues by declaring that 'A key motive for Popper's "demarcation criterion" distinguishing science from "pseudo-science" was to restrict the authority of science to disciplines which used the scientific method.' However, a closer look at Popper’s writing shows that this widespread view is incorrect. In fact, Popper declares (...) in the postscript to the Logic of Scientific Discovery: [I]t is all guesswork, doxa rather than epistēmē… Science has no authority… It represents… our hope of emancipating ourselves from ignorance and narrow-mindedness, from fear and superstition. And this includes… the superstitious belief in the authority of science itself. After briefly defending my contention, with reference to the work of Bartley and some of Popper's statements elsewhere, I will argue that Popper is better understood as attempting to demarcate inquiry from non-inquiry. I also hope to show that this humbler goal is worthwhile, especially when it comes to resisting calls to teach so-called ‘creation science’ in schools. Unfortunately, Popper has become associated with the relatively simplistic view that falsifiability is a demarcation criterion. But Popper recognized, even in the first edition of Logic of Scientific Discovery, that falsifiability alone does not suffice. He was cognisant of the problem posed by Duhem's thesis, and therefore stated: A system such as classical mechanics may be ‘scientific’ to any degree you like; but those who uphold it dogmatically—believing, perhaps, that it is their business to defend such a successful system against criticism as long as it is not conclusively disproved—are adopting the very reverse of that critical attitude which in my view is the proper one for the scientist. This would appear to be why Popper wrote of 'the non-existence of scientific method' above and beyond 'the one method of all rational discussion, and therefore of the natural sciences as well as of philosophy… stating one's problem clearly and examining its various proposed solutions critically'. In short, the critical approach is a crucial part of the demarcation puzzle. In the remainder of the talk, I will develop this solution to the demarcation problem in response to several possible criticisms. Chief among these is that 'creation scientists' do inquire but only with narrow scope. To address this criticism, I will draw on some of my recent work on the roles of criticism and dogmatism in science ; and in particular, I will consider if looking at matters from the group level can help.

In his review of Phillip Grier’s anthology, Dialectic and Contemporary Science, Darrel Christensen expresses his regret that I “did not find occasion… to give more attention… to the sorts of well-informed and pointed criticism that E. McMullin raised.. in ‘Is the Progress of Science Dialectical?’” In that book it would hardly have been possible or appropriate, for me to have done so, because I did not write it, and although the editor invited me to respond to the authors who contributed, (...) Ernan McMullin was not one of them. The paper to which Christensen refers was presented to the first meeting of the Hegel Society of America in 1970, at which I was present; but after so long an interval of time I cannot now remember if or how, I responded to it. So far as my recollection serves, my own paper, although distributed to those attending the meeting, was not read and was not fully discussed. So there may well be some need for taking up Christensen’s challenge, even at this late hour. (shrink)
Modeling user behaviors as sequential learning provides key advantages in predicting future user actions, such as predicting the next product to purchase or the next song to listen to, for the purpose of personalized search and recommendation. Traditional methods for modeling sequential user behaviors usually depend on the premise of Markov processes, while recently recurrent neural networks have been adopted to leverage their power in modeling sequences. In this paper, we propose integrating attention mechanism into RNNs for better modeling sequential (...) user behaviors. Specifically, we design a network featuring Attention with Long-term Interval-based Gated Recurrent Units to model temporal sequences of user actions. Compared to previous works, our network can exploit the information of temporal dimension extracted by time interval-based GRU in addition to normal GRU to encoding user actions and has a specially designed matrix-form attention function to characterize both long-term preferences and short-term intents of users, while the attention-weighted features are finally decoded to predict the next user action. We have performed experiments on two well-known public datasets as well as a huge dataset built from real-world data of one of the largest online shopping websites. Experimental results show that the proposed ALI-GRU achieves significant improvement compared to state-of-the-art RNN-based methods. ALI-GRU is also adopted in a real-world application and results of the online A/B test further demonstrate its practical value. (shrink)
_Popper’s Critical Rationalism_ presents Popper’s views on science, knowledge, and inquiry, and examines the significance and tenability of these in light of recent developments in philosophy of science, philosophy of probability, and epistemology. It develops a fresh and novel philosophical position on science, which employs key insights from Popper while rejecting other elements of his philosophy. Central theses include: Crucial questions about scientific method arise at the level of the group, rather than that of the individual. Although criticism is vital (...) for science, dogmatism is important too. Belief in scientific theories is permissible even in the absence of evidence in their favour. The aim of science is to eliminate false theories. Critical rationalism can be understood as a form of virtue epistemology. (shrink)
This paper argues that talk of ‘the aim of science’ should be avoided in the philosophy of science, with special reference to the way that van Fraassen sets up the difference between scientific realism and constructive empiricism. It also argues that talking instead of ‘what counts as success in science as such’ is unsatisfactory. The paper concludes by showing what this talk may be profitably replaced with, namely specific claims concerning science that fall into the following categories: descriptive, evaluative, normative, (...) and definitional. There are two key advantages to this proposal. First, realism and its competitors may be understood to consist of highly nuanced variants. Second, scientific realism and its competitors may be understood as something other than ‘all or nothing’ theses about science. More particularly, one may accept that there are general claims concerning science in some of the identified categories, but deny that there are such claims in the others. (shrink)
In Making Sense of Life , Keller emphasizes several differences between biology and physics. Her analysis focuses on significant ways in which modelling practices in some areas of biology, especially developmental biology, differ from those of the physical sciences. She suggests that natural models and modelling by homology play a central role in the former but not the latter. In this paper, I focus instead on those practices that are importantly similar, from the point of view of epistemology and cognitive (...) science. I argue that concrete and abstract models are significant in both disciplines, that there are shared selection criteria for models in physics and biology, e.g. familiarity, and that modelling often occurs in a similar fashion.

In Medicine, Society, and Faith in the Ancient and Medieval Worlds Darrel Amundsen explores the disputed boundaries of medicine and Christianity by focusing on the principle of the sanctity of human life, including the duty to treat or attempt to sustain the life of the ill. As he examines his themes and moves from text to context, Amundsen clarifies a number of Christian principles in relation to bioethical issues that are hotly debated today. In his examination of the moral stance (...) of the earliest syphilographers, for example, he finds insights into the ethical issues surrounding the treatment of AIDS, which he believes has its closest historical antecedent not in plague but in syphilis. He also shows that the belief that all healing comes from God, whether directly, through prayer, or through the use of medicine -- a sentiment commonly held by contemporary Christians -- cannot be accurately attributed to any extant source from the patristic period. Indeed, all the Church Fathers were convinced that healing sometimes came from evil sources: Satan and his demons were able to heal, for example, and Asclepius was a demon "to be taken very seriously indeed.".

First, I answer the controversial question ’What is scientific realism?’ with extensive reference to the varied accounts of the position in the literature.

This book examines the threat that climate change poses to the projects of poverty eradication, sustainable development, and biodiversity preservation. It offers a careful discussion of the values that support these projects and a critical evaluation of the normative bases of climate change policy. This book regards climate change policy as a public problem that normative philosophy can shed light on. It assumes that the development of policy should be based on values regarding what is important to respect, preserve, and (...) protect. What sort of climate change policy do we owe the poor of the world who are particularly vulnerable to climate change? Why should our generation take on the burden of mitigating climate change that is caused, in no small part, by emissions from people now dead? What value is lost when natural species go extinct, as they may well do en masse because of climate change? This book presents a broad and inclusive discussion of climate change policy, relevant to those with interests in public policy, development studies, environmental studies, political theory, and moral and political philosophy.

Stanford’s argument against scientific realism focuses on theories, just as many earlier arguments from inconceivability have. However, there are possible arguments against scientific realism involving unconceived (or inconceivable) entities of different types: observations, models, predictions, explanations, methods, instruments, experiments, and values. This paper charts such arguments. In combination, they present the strongest challenge yet to scientific realism.
Roughly, instrumentalism is the view that science is primarily, and should primarily be, an instrument for furthering our practical ends. It has fallen out of favour because historically influential variants of the view, such as logical positivism, suffered from serious defects. -/- In this book, however, Darrell P. Rowbottom develops a new form of instrumentalism, which is more sophisticated and resilient than its predecessors. This position—‘cognitive instrumentalism’—involves three core theses. First, science makes theoretical progress primarily when it furnishes us (...) with more predictive power or understanding concerning observable things. Second, scientific discourse concerning unobservable things should only be taken literally in so far as it involves observable properties or analogies with observable things. Third, scientific claims about unobservable things are probably neither approximately true nor liable to change in such a way as to increase in truthlikeness. -/- There are examples from science throughout the book, and Rowbottom demonstrates at length how cognitive instrumentalism fits with the development of late nineteenth- and early twentieth-century chemistry and physics, and especially atomic theory. Drawing upon this history, Rowbottom also argues that there is a kind of understanding, empirical understanding, which we can achieve without having true, or even approximately true, representations of unobservable things. In closing the book, he sets forth his view on how the distinction between the observable and unobservable may be drawn, and compares cognitive instrumentalism with key contemporary alternatives such as structural realism, constructive empiricism, and semirealism. -/- Overall, this book offers a strong defence of instrumentalism that will be of interest to scholars and students working on the debate about realism in philosophy of science.

J. S. Mill's distinction between higher and lower pleasures is often thought to conflict with his commitment to psychological and ethical hedonism: if the superiority of higher pleasures is quantitative, then the higher/lower distinction is superfluous and Mill contradicts himself; if the superiority of higher pleasures is not quantitative, then Mill's hedonism is compromised.
I answer Alvin Plantinga's challenge to provide a ‘proper’ de jure objection to religious belief. What I call the ‘sophisticates’ evidential objection' concludes that sophisticated Christians lack epistemic justification for believing central Christian propositions. The SEO utilizes a theory of epistemic justification in the spirit of the evidentialism of Richard Feldman and Earl Conee. I defend philosophical interest in the SEO against objections from Reformed epistemology, by addressing Plantinga's criteria for a proper de jure objection, his anti-evidentialist arguments, and the (...) relevance of ‘impulsional evidence’. I argue that no result from Plantinga-style Reformed epistemology precludes the reasons I offer in favour of giving the SEO its due philosophical attention. (shrink)
In this paper I argue that hope is best understood as a compound psychological state. When we take hope according to the details of this account, we are in a good position to understand why it is a political virtue of persons. I also argue that securing the institutional bases of hope is a virtue of state institutions, particularly in states in transition from severe injustice. And, finally, when the bases are secure, a person who fails to hope for the (...) political future is in that regard prima facie blameworthy. (shrink)
Responsibility is often thought of as primarily a legal concept. Even when it is moral responsibility that is at issue, it is assumed that it is above all in moralities based on law-centered patterns and models that responsibility takes center stage, so that responsibility is a legal concept at its core, and is applicable to the realm of private morality only by extension and analogy.
We argue that the inference from dispositional essentialism about a property (in the broadest sense) to the metaphysical necessity of laws involving it is invalid. Let strict dispositional essentialism be any view according to which any given property’s dispositional character is precisely the same across all possible worlds. Clearly, any version of strict dispositional essentialism rules out worlds with different laws involving that property. Permissive dispositional essentialism is committed to a property’s identity being tied to its dispositional profile or causal (...) role, yet is compatible with moderate interworld variation in a property’s dispositional profile. We provide such a model of dispositional essentialism about a property and metaphysical contingency of the laws involving it. (shrink)
First, I argue that scientific progress is possible in the absence of increasing verisimilitude in science’s theories. Second, I argue that increasing theoretical verisimilitude is not the central, or primary, dimension of scientific progress. Third, I defend my previous argument that unjustified changes in scientific belief may be progressive. Fourth, I illustrate how false beliefs can promote scientific progress in ways that cannot be explicated by appeal to verisimilitude.
Anthropogenic climate change is a global process affecting the lives and well-being of millions of people now and countless number of people in the future. For humans, the consequences may include significant threats to food security globally and regionally, increased risks of from food-borne and water-borne as well as vector-borne diseases, increased displacement of people due migrations, increased risks of violent conflicts, slowed economic growth and poverty eradication, and the creation of new poverty traps. Principles of justice are statements of (...) what persons are owed either by others or by institutions and policies. Climate change gives rise to many concern of justice. This article briefly summarizes some of the most important of these, including claims to have climate change mitigated, claims regarding the sharing of the costs of climate change mitigation, claims for investment into adaptation, and claims to be compensated.

When a doctor tells you there’s a one percent chance that an operation will result in your death, or a scientist claims that his theory is probably true, what exactly does that mean? Understanding probability is clearly very important, if we are to make good theoretical and practical choices. In this engaging and highly accessible introduction to the philosophy of probability, Darrell Rowbottom takes the reader on a journey through all the major interpretations of probability, with reference to real–world (...) situations. In lucid prose, he explores the many fallacies of probabilistic reasoning, such as the ‘gambler’s fallacy’ and the ‘inverse fallacy’, and shows how we can avoid falling into these traps by using the interpretations presented. He also illustrates the relevance of the interpretation of probability across disciplinary boundaries, by examining which interpretations of probability are appropriate in diverse areas such as quantum mechanics, game theory, and genetics. Using entertaining dialogues to draw out the key issues at stake, this unique book will appeal to students and scholars across philosophy, the social sciences, and the natural sciences. (shrink)
Libertarianism needs a theory of class. This claim may meet with resistance among some libertarians. A few will say: “The analysis of society in terms of classes and class struggles is a specifically Marxist approach, resting on assumptions that libertarians reject. Why should we care about class?” A greater number will say: “We recognize that class theory is important, but libertarianism doesn't need such a theory, because it already has a perfectly good one.”.
This article discusses two doctrines of jus ex bello concerning whether and how to end wars. In Section I, I defend the claim that there is a distinct morality of ending wars. Section II rebuts a challenge that the account is too permissive of war. Section III rejects a forward-looking conception of proportionality for jus ex bello. In Section IV, I allow an exception in cases in which the just cause for the war has changed. In Section V, I defend (...) five principles governing how to end a war. (shrink)
We began with three propositions: that people have a right not to be treated as mere means to the ends of others, that a woman who voluntarily becomes pregnant nevertheless has the right to an abortion, and that a woman who voluntarily gives birth does not have a right to abandon her child until she finds a substitute caretaker. These propositions initially seemed inconsistent, for the prohibition on treating others as mere means appeared to rule out the possibility of positive (...) rights, thus making it impossible to countenance the right to abort or the right not to be abandoned . But we have seen that the prohibition on treating people as mere means to the ends of others is best understood as ruling out basic positive rights while permitting derivative ones. Since a willing mother is responsible for bringing her child into the world in the first place, she cannot abandon it without violating its negative right not to be killed, and so such a child has a derivative positive right not to be abandoned. A pregnant woman, on the other hand, has a negative right not to have her body invaded, and from this negative right derives a positive right to abort her fetus, so long as doing so is not disproportionate to the seriousness of the threat . Therefore, far from being in conflict, propositions , , and have been shown to be in harmony with one another, the latter two being plausibly grounded in the first. Insofar as we have reason to accept , then, we have reason to accept and . Moreover, we have seen that a proper understanding of allows us to embed and in a larger moral perspective in which the limits of compulsory altruism are firmly drawn: enforceable rights to the use or assistance of others may be allowed into the moral domain only if they are “sponsored” by some negative right. Every putative positive right must find such a sponsor, or perish. (shrink)
Popper repeatedly emphasised the significance of a critical attitude, and a related critical method, for scientists. Kuhn, however, thought that unquestioning adherence to the theories of the day is proper; at least for ‘normal scientists’. In short, the former thought that dominant theories should be attacked, whereas the latter thought that they should be developed and defended. Both seem to have missed a trick, however, due to their apparent insistence that each individual scientist should fulfil similar functions. The trick is (...) to consider science at the group level; and doing so shows how puzzle solving and ‘offensive’ critical activity can simultaneously have a legitimate place in science. This analysis shifts the focus of the debate. The crucial question becomes ‘How should the balance between functions be struck?’. (shrink)

This paper challenges a recent argument of Bird’s, which involves imagining that Réné Blondlot’s belief in N-rays was true, in favour of the view that scientific progress should be understood in terms of knowledge rather than truth. By considering several variants of Bird’s thought-experiment, it shows that the semantic account of progress cannot be so easily vanquished. A key possibility is that justification is only instrumental in, and not partly constitutive of, progress.
This paper challenges Bird’s view that scientific progress should be understood in terms of knowledge, by arguing that unjustified scientific beliefs (and/or changes in belief) may nevertheless be progressive. It also argues that false beliefs may promote progress.
Abstract Right intention is one of the staple criteria of traditional just war theory. In classical terms, right intention is met when a belligerent aims to achieve a just and peaceful order. I will address the problem of determining when a belligerent has satisfied the criterion of right intention. I will argue that right intention is determined by observing a belligerent's acts during and after a conflict. Intention is not merely a private mental act known ultimately only by the people (...) who express the intentions of their governments. Rather, right intention is a communal, public act, for the observable circumstances are how intention is determined. I will demonstrate the effectiveness of this way of determining intention by concentrating on the stated intentions of the Allies before World War II and of the U.S. before the First and Second Gulf Wars. The goal of the paper is to demonstrate that the international community can check a belligerent's stated intentions both while the war is in progress and after the war has ended. I will argue that how well a belligerent conforms to the jus in bello and, when appropriate, to the jus post bellum, provide the international community with much of the information it needs to determine whether or not right intention has been met.

Ten years on from the first issue of the Journal of Global Ethics, Darrel Moellendorf and Heather Widdows reflect on the current state of research in global ethics. To do this, they summarise a recent comprehensive road map of the field and provide a map of research by delineating the topics and approaches of leading scholars of global ethics collected together in the recently published Routledge Handbook of Global Ethics which they have co-edited. Topics fall under issues of war, conflict (...) and violence; poverty and development; economic justice; bioethics and health justice; and environmental and climate justice. In all these areas, ethicists are becoming ever more engaged in the details and mechanisms of actually delivering justice in the real world. (shrink)
When do we agree? The answer might once have seemed simple and obvious; we agree that p when we each believe that p. But from a formal epistemological perspective, where degrees of belief are more fundamental than beliefs, this answer is unsatisfactory. On the one hand, there is reason to suppose that it is false; degrees of belief about p might differ when beliefs simpliciter on p do not. On the other hand, even if it is true, it is too (...) vague; for what it is to believe simpliciter ought to be explained in terms of degrees of belief. This paper presents several possible notions of agreement, and corresponding notions of disagreement. It indicates how the findings are fruitful for the epistemology of disagreement, with special reference to the notion of epistemic peerhood. (shrink)
This paper compares and contrasts the concept of a stance with that of a paradigm qua disciplinary matrix, in an attempt to illuminate both notions. First, it considers to what extent it is appropriate to draw an analogy between stances and disciplinary matrices. It suggests that despite first appearances, a disciplinary matrix is not simply a stance writ large. Second, it examines how we might reinterpret disciplinary matrices in terms of stances, and shows how doing so can provide us with (...) a better insight into non-revolutionary science. Finally, it identifies two directions for future research: “Can the rationality of scientific revolutions be understood in terms of the dynamic between stances and paradigms?” and “Do stances help us to understand incommensurability between disciplinary matrices?”.

UNFCCC norms tightly constrain the range of acceptable agreements for the distribution of burdens to mitigate climate change, restricting us to two viable guiding principles: the equitable distribution of responsibilities and the right to development.

We have three goals in this paper. First, we outline an ontology of stance, and explain the role that modes of engagement and styles of reasoning play in the characterization of a stance. Second, we argue that we do enjoy a degree of control over the modes of engagement and styles of reasoning we adopt. Third, we contend that maximizing one’s prospects for change also maximizes one’s rationality.

Schwitzgebel (2001) — henceforth 'S' — offers three examples in order to convince us that there are situations in which individuals are neither accurately describable as believing that p or failing to so believe, but are rather in 'in-between states of belief'. He then argues that there are no 'Bayesian' or representational strategies for explicating these, and proposes a dispositional account. I do not have any fundamental objection to the idea that there might be 'in-between states of belief'. What I (...) shall argue, rather, is that: (I) S does not provide a convincing argument that there really are such states; (II) S does not show, as he claims, that 'in-between states of belief' could not be accounted for in terms of degrees of belief; (III) S’s dispositional account of 'in-between states of belief' is more problematic than the 'degree of belief' alternative.

Both Popper and van Fraassen have used evolutionary analogies to defend their views on the aim of science, although these are diametrically opposed. By employing Price's equation in an illustrative capacity, this paper considers which view is better supported. It shows that even if our observations and experimental results are reliable, an evolutionary analogy fails to demonstrate why conjecture and refutation should result in: (1) the isolation of true theories; (2) successive generations of theories of increasing truth-likeness; (3) empirically adequate (...) theories; or (4) successive generations of theories of increasing proximity to empirical adequacy. Furthermore, it illustrates that appeals to induction do not appear to help. It concludes that an evolutionary analogy is only sufficient to defend the notion that the aim of science is to isolate a particular class of false theories, namely those that are empirically inadequate.
