I propose a distinct type of robustness, which I suggest can support a confirmatory role in scientific reasoning, contrary to the usual philosophical claims. In model robustness, repeated production of the empirically successful model prediction or retrodiction against a background of independentlysupported and varying model constructions, within a group of models containing a shared causal factor, may suggest how confident we can be in the causal factor and predictions/retrodictions, especially once supported by a variety of evidence framework. I present climate (...) models of greenhouse gas global warming of the 20th Century as an example, and emphasize climate scientists’ discussions of robust models and causal aspects. The account is intended as applicable to a broad array of sciences that use complex modeling techniques. (shrink)

Shelly Kagan has recently defended the view that it is morally worse for a human being to suffer some harm than it is for a lower animal (such as a dog or a cow) to suffer a harm that is equally severe (ceteris paribus). In this paper, I argue that this view receives rather less support from our intuitions than one might at first suppose. According to Kagan, moreover, an individual’s moral status depends partly upon her ‘modal capacities.’ In this (...) paper, I argue that the most natural strategy for justifying Kagan’s theory faces some important challenges. More generally, I argue that philosophers who wish to defend the view that human beings have a higher moral status than that of the lower animals face a dilemma. Either their theory of moral status will imply (unacceptably) that some severely cognitively impaired human beings have a significantly lower moral status than that of typical human beings, or these philosophers will be forced to ground moral status in a set of properties so far removed from a subject’s actual capacities that it will become difficult to see why these kinds of properties should have such moral importance.

My contribution to this Symposium focuses on the links between sexuality and reproduction from the evolutionary point of view.' The relation between women's sexuality and reproduction is particularly importantb ecause of a vital intersectionb etweenp olitics and biology feminists have noticed, for more than a century, that women's identity is often defined in terms of her reproductive capacity. More recently, in the second wave of the feminist movement in the United States, debates about women'si dentityh ave explicitlyi ncludeds exuality;m uch (...) feminist argument in the late 1960's and early 1970's involved an attempt to separate out an autonomous female sexuality from women's reproductive functions. It is especially relevant, then, to examine biological arguments, particularlye volutionarya rgumentst, o see what they say about whether and how women's sexuality is related to reproduction.

Climate change assessments rely upon scenarios of socioeconomic developments to conceptualize alternative outcomes for global greenhouse gas emissions. These are used in conjunction with climate models to make projections of future climate. Specifically, the estimations of greenhouse gas emissions based on socioeconomic scenarios constrain climate models in their outcomes of temperatures, precipitation, etc. Traditionally, the fundamental logic of the socioeconomic scenarios—that is, the logic that makes them plausible—is developed and prioritized using methods that are very subjective. This introduces a fundamental (...) challenge for climate change assessment: The veracity of projections of future climate currently rests on subjective ground. We elaborate on these subjective aspects of scenarios in climate change research. We then consider an alternative method for developing scenarios, a systems dynamics approach called ‘Cross-Impact Balance’ (CIB) analysis. We discuss notions of ‘objective’ and ‘objectivity’ as criteria for distinguishing appropriate scenario methods for climate change research. We distinguish seven distinct meanings of ‘objective,’ and demonstrate that CIB analysis is more objective than traditional subjective approaches. However, we also consider criticisms concerning which of the seven meanings of ‘objective’ are appropriate for scenario work. Finally, we arrive at conclusions regarding which meanings of ‘objective’ and ‘objectivity’ are relevant for climate change research. Because scientific assessments uncover knowledge relevant to the responses of a real, independently existing climate system, this requires scenario methodologies employed in such studies to also uphold the seven meanings of ‘objective’ and ‘objectivity.’.

It is a commonly-held belief that ignorance excuses. But what of moral ignorance? Is a person blameless who acts from “false” moral principles? In this paper I shall try to show that such a person is blameworthy. I shall produce an argument that connects the acceptance of moral principles with character, character with moral responsibility, and moral responsibility with the justifiability of blame.

This paper defends the claim that mere temporal proximity always and without exception strengthens certain moral duties, including the duty to save – call this view Robust Temporalism. Although almost all other moral philosophers dismiss Robust Temporalism out of hand, I argue that it is prima facie intuitively plausible, and that it is analogous to a view about special obligations that many philosophers already accept. I also defend Robust Temporalism against several common objections, and I highlight its relevance to a (...) number of practical policy debates, including longtermism. My conclusion is that Robust Temporalism is a moral live option, that deserves to be taken much more seriously in the future. (shrink)

climate scientists have been engaged in a decades-long debate over the standing of satellite measurements of the temperature trends of the atmosphere above the surface of the earth. This is especially significant because skeptics of global warming and the greenhouse effect have utilized this debate to spread doubt about global climate models used to predict future states of climate. I use this case from an under-studied science to illustrate two distinct philosophical approaches to the relation among data, scientists, measurement, models, (...) and theory. I argue that distinguishing between 'direct' empiricist and 'complex' empiricist approaches helps us understand and analyze this important scientific episode. I also introduce a complex empiricist account of testing and evaluation, and contrast it with the basic Hypothetico-Deductive approach to the climate models used by the direct empiricists. This more developed complex empiricist apporach will serve philosophy of science well, as computational models become more wide-spread in the sciences. (shrink)

There are different groups in society who may be considered vulnerable, for example those experiencing mental or physical health issues, learning disabilities, prisoners or children. There are, however, other groups in society who may also be regarded as vulnerable, such as those who are bereaved. Vulnerability in relation to the bereaved occurs as a result of experiencing a normal life event, death or a loss. In this situation vulnerability may be transient and, depending upon the management of the bereavement, generally (...) temporary. Unlike the aforementioned groups, participants required for this type of research (bereavement, death and dying) are able to consent themselves into projects, and the capacity to do so is not an issue. Undertaking research with those who may be considered vulnerable into sensitive, emotive topics such as death and dying can create difficulties for the National Research Ethics Service (NRES), making it difficult to get approval for such studies. It appears that the ethical issues are concerned with not wishing to cause distress to participants when asked for research purposes to recollect what for some may have been emotionally challenging and traumatic events. The article offers a narrative, reflective account of the above from several perspectives: being employed as a contract researcher in a university; having experience of being an active member of a National Health Service Research Ethics Committee; and later assuming the role of full-time postgraduate (PhD) student requiring ethical approval to undertake research with what may be considered a vulnerable group involving a sensitive and emotive topic. Valuable insights from participants – their views on participation in an emotive research project and good practice in research having been explored via questionnaire – are highlighted and discussed.

The aim of this article is to examine both the work of Judith Butler on gender performativity and examples of how Butler's writings have been appropriated by certain other writers. I explore three areas in particular: the relation between performance and performativity in the work of Butler and her `adherents'; the developmental changes in Butler's argument between Gender Trouble and Bodies That Matter; and the question of the effectiveness of the politics of parody. I argue that it is the ambiguities (...) in Butler's own several accounts of the distinction between performance and performativity that fuel the readings of the politics of performance as the province of the autonomous subject - a perspective at variance with Butler's own. In addition, I explore the deficiencies in Butler's account of politics, especially her denial of the significance of the context on the efficacy of political interventions. (shrink)

The continual background awareness of duration is an essential structure of consciousness, conferring temporal extension to the many objects of awareness within the evanescent sensory present. Seeking the possible neural correlates of ubiquitous temporal awareness, this article reexamines fMRI data from off-task “default mode” periods in 25 healthy subjects studied by Grady et al. , 2005). “Brain reading” using support vector machines detected information specifying elapsed time, and further analysis specified distributed networks encoding implicit time. These networks fluctuate; none are (...) continuously active during DM. However, the aggregate regions of greatest variability closely resemble the default mode network. It appears that the default mode network has an important role as a state-dependent monitor of temporality. (shrink)

In On the Edge of Anarchy, A. John Simmons simultaneously pursues two distinguishable ends: to defend an interpretation of Locke as a “pure consent” theorist the essence of whose theory is that only actual voluntary individual consent can ground political obligations and authority, and to defend pure consent theory as the best theory of political obligation. Both ends are pursued under the heading of justifying “Lockean” consent theory, and the arguments for them overlap considerably because most of Simmons’s defense of (...) his interpretation of Locke’s theory depends on his arguments that the position he attributes to Locke is, for independent philosophical reasons, the most defensible version of “voluntaristic” theory. Two of the very interesting, and surprising, inferences Simmons defends in this book are that believing ourselves to be naturally free from political obligation implies that most existing states are illegitimate, and that Locke was committed to the view that “political drudgery,” a condition in which all of our rights are alienated to the government, although imprudent, is not morally impermissible.

Since the fundamental challenge that I laid at the doorstep of the pluralists was to defend, with nonderivative models, a strong notion of genic cause, it is fatal that Waters has failed to meet that challenge. Waters agrees with me that there is only a single cause operating in these models, but he argues for a notion of causal ‘parsing’ to sustain the viability of some form of pluralism. Waters and his colleagues have some very interesting and important ideas about (...) the sciences, involving pluralism and parsing or partitioning causes, but they are ideas in search of an example. He thinks he has found an example in the case of hierarchical and genic selection. I think he has not. (shrink)

As the new Cell-free DNA (Cf-DNA) prenatal screening test for Down syndrome was being introduced into the UK’s fetal anomaly screening program, Down syndrome charities had an opportunity to participate. An experience of co-production where we were the minority voice then followed. This paper explores that process and our experience as a charity. Institutional and societal structures meant that it was difficult to be heard and a significant amount of bias was noted within the program. Consequently, our viewpoints were often (...) considered and then dismissed. However, at times we were listened to, and feel that there were some valuable changes made resulting from our involvement. The end product was far from reflective of all that we stand for, and there are still lessons to be learned in England about the need to place a higher value on minority voices of lived experience in a co-production exercise.

Spinoza is a key figure in modern philosophy. _Ethics_ is his most studied and well known work. Being both up-to-date and clear, this Guidebook is designed to lead the reader through this complex seminal text. _Spinoza's Ethics_ introduces and assess: * Spinoza'a life, and its connection with his thought * The text of the _Ethics_ * Spinoza's continuing relevence to contemporary philosophy.

The question of determining the genuine works of Hippocrates, a topic already much discussed by the ancient commentators, still continues to be actively debated, although the disagreements among scholars remain, it seems, almost as wide as ever. In comparatively recent times, Edelstein's IIEPI AEPQN and two subsequent studies of his written in the 1930s and marked a turning-point in that they presented a particularly clear and comprehensive statement of the sceptical view, according to which Hippocrates is, as Wilamowitz put it (...) long ago, ‘ein beriihmter Name ohne den Hintergrund irgend einer Schrift’.

Drawing on the work of Michèle Le Dœuff, this paper uses the idea of “philosophical imagination” to make visible the historical intersection between philosophical ideas, social practice, and institutional structures. It explores the role of ideas of “terra nullius” and of the “doomed race” in the formation of some crucial ways in which non-indigenous Australians have imagined their relations with indigenous peoples. The author shows how feminist reading strategies that attend to the imaginary open up ways of rethinking processes of (...) inclusion and exclusion. (shrink)

The idea of a property's being supervenient on a class of properties is familiar from much philosophical literature. We give this idea a linguistic turn by converting it into the idea of a predicate symbol's being supervenient on a set of predicate symbols relative to a (first order) theory. What this means is that according to the theory, any individuals differing in respect to whether the given predicate applies to them also differ in respect to the application of at least (...) one of the predicates in the set. The latter relationship we show turns out to coincide with something antecedently familiar from work on definability: with what is called the piecewise (or modelwise) definability, in the theory in question, of the given predicate in terms of those in the set.

One of the disadvantages of redistributive taxation is that it reduces people’s financial incentives to increase national wealth and benefit others by engaging in productive activities. It is natural to suppose that the severity of this disadvantage will be proportional to the socially prevailing level of human selfishness. Thus several advocates of redistribution (G.A. Cohen, Ha-Joon Chang among others) have argued that this disadvantage of redistribution need not be as severe as critics often suggest, because human beings need not be (...) so selfish. My aim in this paper is to argue that, even in a society entirely composed of unselfish and impartially beneficent individuals, redistributive taxation would still discourage activities that contribute to national wealth, because differing individuals have different views about what counts as benefiting themselves and others. I also relate my discussion to G.A. Cohen’s influential ‘camping trip’ argument for socialism (from Why Not Socialism?). (shrink)

To william james, conscious life was a stream; to Edmund Husserl, a flow. These metaphors point to the marvelous continuity of experience as it weaves through the world of thought and things. We might similarly talk about the flow of the body, as I reach for my cup of coffee. A physiologist could decompose the action, isolating the contribution of each muscle and joint to the whole. This functional analysis would constitute one form of explanation of the movement. As we (...) replace "I grab the cup" with the physiologist's account, there is a shift in level of description and a turn toward underlying processes, but the physiologist has added nothing to nature. Explanation of this sort, functional reduction, is simply a .. (shrink)

Algorithms for approximate Bayesian inference, such as those based on sampling (i.e., Monte Carlo methods), provide a natural source of models of how people may deal with uncertainty with limited cognitive resources. Here, we consider the idea that individual differences in working memory capacity (WMC) may be usefully modeled in terms of the number of samples, or “particles,” available to perform inference. To test this idea, we focus on two recent experiments that report positive associations between WMC and two distinct (...) aspects of categorization performance: the ability to learn novel categories, and the ability to switch between different categorization strategies (“knowledge restructuring”). In favor of the idea of modeling WMC as a number of particles, we show that a single model can reproduce both experimental results by varying the number of particles—increasing the number of particles leads to both faster category learning and improved strategy‐switching. Furthermore, when we fit the model to individual participants, we found a positive association between WMC and best‐fit number of particles for strategy switching. However, no association between WMC and best‐fit number of particles was found for category learning. These results are discussed in the context of the general challenge of disentangling the contributions of different potential sources of behavioral variability. (shrink)

It is well known that no consistent normal modal logic contains (as theorems) both ♦A and ♦¬A (for any formula A). Here we observe that this claim can be strengthened to the following: for any formula A, either no consistent normal modal logic contains ♦A, or else no consistent normal modal logic contains ♦¬A.

Today the study of Hobbes is both reputable and flourishing, to judge by the numbers in recent years of publications, submissions, conferences, workshops, and sessions at professional meetings devoted to Hobbes, along with growing interest from scholars in China and Latin America. I recently conducted a survey of colleagues working on Hobbes; a non-scientific survey, it included scholars working in a variety of departments. This research note reports the views of more than three dozen respondents, who answered three questions: (1) (...) what has been at stake in Hobbes debates?; (2) have any conclusions been decisively established?; and (3) what are the open questions for the future? The answers evidence a lack of consensus but also demonstrate that we have increasingly refined and sophisticated theoretical arguments for and against contending positions. (shrink)

In this essay an ‘objective’ account of intrinsic value is proposed and partly defended. It is claimed that a kind of value exists which is, or may reasonably be supposed to be, a property of certain objects. The presence of such value is not to be wholly accounted for as the ‘projection’ of certain human feelings elicited by the object thought to be of value, nor by the object's meeting certain operative human conventions prescribing what is to be admired, nor (...) by its being conformable, in some way, to human needs or desires. Hume, of course, would have none of this. It is hoped to show that if one adopts Hume's account, then his attempt to show that there nevertheless will be convergence in the long run as to what is of aesthetic value is forced and unsuccessful. By contrast, on the ‘objective’ account convergence is to be expected. This, of course, only shows the superiority of the ‘objective’ account so long as there is an expectation of long-term convergence. This is not an expectation of most contemporary value ‘subjectivists’, and therefore the argument will not be directly relevant to their positions. (shrink)

The Lion King is a Disney version of Shakespeare's most famous play, Hamlet. It was going to be the first Disney animated feature film based on an original concept – no source material. Hamlet's famous “to be or not to be” soliloquy rings with existential absurdity, and his morbid brooding reflects a sense of meaninglessness. The existential question of being permeates both play and film. The Lion King transfers Hamlet's contemplative question about life and death to not one but two (...) delightful characters, perfect for manufacture and distribution as stuffed animals, plastic action figures, plates, cups, stickers, one names it. After he leaves the Pride Lands, Simba runs into Timon the meerkat and Pumbaa the warthog who offer him an answer to Hamlet's question. The Lion King ends with song and the celebration of Simba's own son – the circle of life continues. (shrink)
