Understanding the intersections of science and publics has led to research on how diverse publics interpret scientific information and form positions on science-related issues. Research demonstrates that attitudes toward science, political and religious orientation, and other social factors affect adult interactions with science, which has implications for how adults influence K-12 STEM (science, technology, engineering, and mathematics) education. Based on a statewide survey of adults in Idaho (n = 407), a politically and religiously conservative western state, we demonstrate how attitudes (...) toward science, measured through a composite measure “orientation toward science,” and other social factors are correlated with support for STEM education. Results show that “orientation toward science,” along with political orientation and respondents’ perceptions of feeling informed about science, predicts behavior intentions to support STEM education. Our findings suggest that a nuanced and localized approach to fostering support for K-12 STEM education would resonate with populations regardless of political orientation, and they illuminate new ways of thinking about how political orientation more generally impacts thinking about science in the context of complicated “socio-scientific relations.” In exploring how people think about science in a politically and religiously conservative state, we provide insights on potential outcomes in other states, should conservative ideology spread. We argue that the publics’ relationship with science and, by extension, support for science education, is more fluid, as many of us suspect, than ideological polemics suggest. (shrink)

Over the past few decades, public anxiety about how people interact with science has spawned cycles of discourse across a wide range of media, public and private initiatives, and substantial research endeavors. National and international STEM (science, technology, engineering, and math) education initiatives and research have addressed how students interact with science and pursue careers in STEM fields. Researchers concerned with adult interaction with science have focused on factors that influence how citizens gather and interpret scientific knowledge and form positions (...) on scientific issues, applications, and/or policy in a politicized democratic milieu. Building from research on how the public interacts with science in and outside of formal education, this study focuses on attitudes toward science among students in 4th, 7th, and 10th grades and their parents. Little research to date has paired the STEM experiences of adults with their children. We find that the extent to which parents are positively oriented toward science significantly shapes their children’s attitudes toward science. Furthermore, between 7th and 10th grades, students with parents holding positive orientations toward science are more likely to sustain positive attitudes toward science. Since the foundation for most adults’ interactions with science develops in the K-12 environment, we demonstrate that the foundation, as expressed in adulthood, may directly affect the ways the next generation of students interacts with science. We offer insights into the importance of developing student learning into the social scientific research on public understanding of science and how important scientific issues of today interplay with society.

Storrs McCall presents an original philosophical theory of the nature of the universe based on a striking new model of its space- time structure. He shows how his model illuminates a broad range of subjects, including causation, probability, quantum mechanics, identity, and free will, and argues that the fact that the model throws light on such a large number of problems constitutes strong evidence that the universe is as the model portrays it.

In lieu of an abstract, here is a brief excerpt of the content:Commentary on “Spiritual Experience and Psychopathology”Anthony Storr (bio)Many psychiatrists, including myself, are deeply dissatisfied with current psychiatric taxonomy. Grossly abnormal people like multiple murderers are often deemed sane in law, because they do not happen to exhibit the symptoms of recognized mental illnesses like schizophrenia or manic-depressive psychosis. In contrast, some of those who do exhibit such symptoms, and who therefore risk being labeled psychotic, cannot be considered (...) to be “ill,” and are in fact mentally robust. There is considerable overlap between experiences which psychiatrists call psychotic, and experiences which are generally called spiritual by those who have them.In order to illustrate this overlap, the authors quote three cases of people describing a variety of delusions and hallucinations which would certainly prompt the diagnosis of psychosis—usually some variety of schizophrenia—were it not for the fact that all three claimed that their experiences had been of considerable benefit to them.It is noteworthy that, in each case, the psychotic/spiritual experiences followed a period of stress. The first subject was threatened by legal action; the second had surmounted an episode of depression, but was questioning whether she could continue her career in business; the third was unemployed, in debt, and suspected that he had multiple sclerosis. The first subject developed both grandiose and religious delusions; but the revelations which he claimed were a sign of God’s special grace toward him enabled him to win his law case and set up a charitable institution. The second heard the voice of Jesus summoning her to work for him. She became convinced that she was specially gifted in various parapsychological fields, and became a religious counselor. As the authors point out, “Her experiences, if delusional and hallucinatory, were overwhelmingly positive in their content and fruits.” The third subject also experienced hallucinatory voices which were intensely reassuring, gave him new insight into the nature of reality, and guided his further progress. As a result, he believed that he had such support that “nothing in this world can worry me.” In each case, the psychotic experience proved to be a solution to the subject’s problem, rather than a breakdown ending in admission to a mental hospital. This raises a variety of intellectual problems.The authors suggest that psychotic phenomena may be good or bad, and label the good phenomena “spiritual” and the bad phenomena “pathological.” According to this point of view, psychotic experience need not be considered pathological, especially if consideration is given to the structure of values and beliefs professed by the individual concerned. [End Page 83]I am not happy with this distinction. I entirely agree that psychotic experience may be a solution to a subject’s problems; but whether it is considered spiritual or pathological depends partly upon the nature of the experience, and even more upon the social setting in which it occurs. A grandiose delusion that one is especially selected and addressed by God may cure the depression of someone who has so far considered himself a nonentity if it is accepted by others. In my study of gurus, Feet of Clay (1996), I make the point that a guru seeks disciples because they reinforce his delusions and may, in some instances, keep him out of hospital. Of the three cases described in this paper, the first told “various friends and ministers about them.” The second confided in her priest and was told that her experiences were authentic within their shared Christian belief system. The third did not apparently share his hallucinatory experience with friends; but, when he responded to the invitation to write to the Alister Hardy Research Centre, wrote, “It is fascinating to find I’m not on my own in this. I have naturally queried my own sanity, and generally don’t discuss it....”Medical diagnosis and psychiatric diagnosis are not strictly comparable. If I as a doctor find that X is suffering from diabetes, I can treat X as an isolated entity displaying symptoms and signs of a well-known disease. I cannot do this when X is displaying “psychotic” symptoms; for whether or not those symptoms are regarded as pathological depends upon the social setting in which they... (shrink)

Although Schütz’s relationship with the Austrian school of economics was an intimate one, Lavoie and other Austrian scholars have challenged (a) Schütz’s characterization of praxeology as an objective science of subjective phenomena and (b) the ability of Schütz’s phenomenology, which emphasizes the subjective meanings of actors, to really make sense of spontaneous social orders. It is my contention, however, that Schütz can be adequately defended against both these charges. First, for Schütz, the claim that social science is an objective science (...) of subjective phenomena need not imply apodictic apriorism nor solipsism. Second, in spite of his emphasis on subjective meanings, the study of spontaneous social orders need not be difficult to justify. (shrink)

The title alone of McCall’s book reveals its ambitious enterprise. The book’s structure is a long inference to the best explanation: chapters present problems that are solved by a single, ontological model. Problems as diverse as time flow, quantum measurement, counterfactual semantics, and free will are discussed. McCall’s style of writing is lucid and pointed—in general, very pleasant to read.

The aim of the paper is to prove the consistency of libertarianism. We examine the example of Jane, who deliberates at length over whether to vacation in Colorado (C) or Hawaii (H), weighing the costs and benefits, consulting travel brochures, etc. Underlying phenomenological deliberation is an indeterministic neural process in which nonactual motor neural states n(C) and n(H) corresponding to alternatives C and H remain physically possible up until the moment of decision. The neurophysiological probabilities pr(n(C)) and pr(n(H)) evolve continuously (...) according to the different weights Jane's judgement attaches to C and H at different times during the deliberation. The overall process is indeterministic, since Jane's exact judgemental weighting would vary slightly were the process to be repeated from the same initial conditions. The weighting is however rational, and entirely under Jane's control. This controlled, rational, indeterministic process shows that libertarianism is a consistent philosophical thesis. (shrink)

Anthony Storr offers a lucid and objective look at Freud's major theories, evaluating whether they have stood the test of time, and in the process examines Freud himself in light of his own ideas. 'a model exercise in synthesis, and the final essay on the 'appeal' of psychotherapy is especially neat.' -Independent.

Propositional temporalism is the view that there are temporary propositions: propositions that are true, but not always true. Factual futurism is the view that there are futurist facts: facts that obtain, but that will at some point not obtain. Most A-theoretic views in the philosophy of time are committed both to propositional temporalism and to factual futurism. Mark Richard, Jeffrey King and others have argued that temporary propositions are not fit to be the contents of propositional attitudes, or to be (...) the semantic values of natural language utterances. But these discussions have overlooked another role that the A-theorist’s posits struggle to play: the role of facts in explaining other facts. Focusing on the case of action explanation by reasons, this paper presents the challenge that explanation poses for factual futurism. It then brings that challenge to bear against propositional temporalism and the A-theory more generally. My argument saddles the factual futurist with surprising commitments concerning reasons, facts and explanation. The futurist might accept those commitments and pay the price. The alternative – which I prefer – is to reject factual futurism, and with it the A-theory. (shrink)

Regulators of G protein signaling (RGS) proteins provide timely termination of G protein‐coupled receptor (GPCR) responses. Serving as a central control point in GPCR signaling cascades, RGS proteins are promising targets for drug development. In this review, we discuss the involvement of RGS proteins in the pathophysiology of the gastrointestinal inflammation and their potential to become a target for anti‐inflammatory drugs. Specifically, we evaluate the emerging evidence for modulation of selected receptor families: opioid, cannabinoid and serotonin by RGS proteins. We (...) discuss how the regulation of RGS protein level and activity may modulate immunological pathways involved in the development of intestinal inflammation. Finally, we propose that RGS proteins may serve as a prognostic factor for survival rate in colorectal cancer. The ideas introduced in this review set a novel conceptual framework for the utilization of RGS proteins in the treatment of gastrointestinal inflammation, a growing major concern worldwide.

Self-compassion is a mechanism of symptom improvement in post-traumatic stress disorder, however, the underlying neurobiological processes are not well understood. High levels of self-compassion are associated with reduced activation of the threat response system. Physiological threat responses to trauma reminders and increased arousal are key symptoms which are maintained by negative appraisals of the self and self-blame. Moreover, PTSD has been consistently associated with functional changes implicated in the brain’s saliency and the default mode networks. In this paper, we explore (...) how trauma exposed individuals respond to a validated self-compassion exercise. We distinguish three groups using the PTSD checklist; those with full PTSD, those without PTSD, and those with subsyndromal PTSD. Subsyndromal PTSD is a clinically relevant subgroup in which individuals meet the criteria for reexperiencing along with one of either avoidance or hyperarousal. We use electroencephalography alpha-asymmetry and EEG microstate analysis to characterize brain activity time series during the self-compassion exercise in the three groups. We contextualize our results with concurrently recorded autonomic measures of physiological arousal, parasympathetic activation and self-reported changes in state mood and self-perception. We find that in all three groups directing self-compassion toward oneself activates the negative self and elicits a threat response during the SC exercise and that individuals with subsyndromal PTSD who have high levels of hyperarousal have the highest threat response. We find impaired activation of the EEG microstate associated with the saliency, attention and self-referential processing brain networks, distinguishes the three PTSD groups. Our findings provide evidence for potential neural biomarkers for quantitatively differentiating PTSD subgroups. (shrink)

This article investigates changing parameters of 'privacy' in Britain and their relevance for the redrawing of boundaries between 'acceptable' and 'unacceptable' sexualities. Drawing on Berlant's distinction between 'live' sex acts and 'dead identities', the article suggests that some hitherto 'live' sex act may 'die', leaving others to be rejected and policed, perhaps even with renewed vigour. This may not, however, mean that the normative status of conjugal (hetero)sexuality is moribund: it may merely be reinvented. The article focuses primarily on the (...) heated and often sensationalized public debate on the homosexuality of Members of Parliament which gripped the UK during October and November 1998. Tony Blair's Labour government was elected to power in 1997 under the campaign slogan 'New Labour, New Britain', and the public reaction to the homosexuality of MPs in 1998 led many commentators to conclude that British sexual values were undergoing a profound liberalization. It is questionable, however, whether these 'new' sexual values were actually as new, or as liberal, as they appeared. (shrink)

The relation between Hume’s constructive and skeptical aims has been a central concern for Hume interpreters. Hume’s two definitions of ‘cause’ in the Treatise and first Enquiry apparently represent an important constructive achievement, but this paper argues that the definitions must be understood in terms of Hume’s skepticism. The puzzle I address is simply that Hume gives two definitions rather than one. I use Don Garrett’s interpretation as a foil to develop my alternative skeptical interpretation. Garrett claims the definitions exhibit (...) a general susceptibility to two kinds of definition that all “sense-based concepts” share. Against Garrett, I argue that the definitions express an imperfection Hume finds only in our concept of causation. That imperfection is absent from other sense-based concepts, and prompts skeptical sentiments in Hume’s conclusion to the Treatise’s Book 1. I close by comparing my interpretation with those of Helen Beebee, Stephen Buckle, Galen Strawson and Paul Russell. (shrink)

This volume contains six new and fifteen previously published essays -- plus a new introduction -- by Storrs McCall. Some of the essays were written in collaboration with E. J. Lowe of Durham University. The essays discuss controversial topics in logic, action theory, determinism and indeterminism, and the nature of human choice and decision. Some construct a modern up-to-date version of Aristotle's bouleusis, practical deliberation. This process of practical deliberation is shown to be indeterministic but highly controlled and the antithesis (...) of chance. Others deal with the concept of branching four-dimensional space-time, explain non-local influences in quantum mechanics, or reconcile God's omniscience with human free will. The eponymous first essay contains the proof of a fact that in 1931 Kurt Gödel had claimed to be unprovable, namely that the set of arithmetic truths forms a consistent system. (shrink)

ABSTRACT In their contribution to the first part of this special issue Craig Bourn and Emily Caddick Bourne claim to have solved a puzzle I put forward in my ‘An Insoluble Problem’. Here I argue that their attempt fails.

A theory of temporal passage is put forward which is "objective" in the sense that time flow characterizes the universe independently of the existence of conscious beings. The theory differs from Grunbaum's "mind-dependence" theory, and is designed to avoid Grunbaum's criticisms of an earlier theory of Reichenbach's. The representation of temporal becoming is accomplished by the introduction of indeterministic universe-models; each model representing the universe at a time. The models depict the past as a single four-dimensional manifold, and the future (...) as a branched structure of such manifolds. Time flow is relativistic in that it manifests itself in a frame-dependent (but not observer-dependent) way. The indeterministic character of the universe-models is mirrored in a "temporal" theory of truth which rejects the principle of bivalence, and suitable semantics are provided for this theory. Finally, an account of physical law is given which defines it in terms of physical possibility, rather than vice versa. (shrink)

Friedrich Wilhelm Nietzsche was born on 5 October 1844 and died on 25 August, 1900. From 1889 until his death eleven years later he was physically and mentally ill and incapable of work. It is almost certain that he died of the brain disease known as G.P.I., General Paralysis of the Insane, or general paresis. In the nineteenth century and well into our own era, this was a not uncommon tertiary manifestation of a syphilitic infection which might originally have been (...) contracted many years before. Because the initial stages of syphilis can now be treated with antibiotics, general paresis is rarely seen today. (shrink)

This exciting collection of work introduces a major shift in debates on sexuality: a shift away from discourse, identity and signification, to a radical new conception of bodily materialism. Moving away from the established path known as queer theory, itsuggests an alternative to Butler's matter/representation binary. It thus dares to askhow to think sexuality and sex outside the discursive and linguistic context that hascome to dominate contemporary research in social sciences and humanities. Deleuze and Queer Theory is a provocative and (...) often militant collection that explores a diverse range of themes including: the revisiting of the term 'queer'; a rethinking of the sex-gender distinction as being implied in Queer Theory; an exploration of queer temporalities; the non/re-reading of the homosexual body/desire and the becoming-queer of the Deleuze/Guattari philosophy. It will be essential reading for anyone interested not just in Deleuze's and Guattari's philosophy, but also in the fields of sexuality, gender and feminist theory. (shrink)

Underwear is the most intimate form of dress, and the type of underwear known as ‘lingerie’ is particularly invested with meanings of femininity, sexuality and pleasure. This article focuses on mass-market lingerie and is based on an ethnographic study of Ann Summers home shopping parties at which lingerie, sex toys and other ‘personal’ products are sold to women in the UK. The analysis draws on the work of Bourdieu and Skeggs to argue that the apparently ‘private’ world of lingerie is (...) simultaneously part of the ‘public’ world of class distinction. The class connotations of mass-market lingerie are not simply aspirational, but are also used by working- and lower-middle-class women to distinguish themselves from ‘posh’ women who are thereby defined as pretentious, boring, snobbish or tasteless. The article concludes that the processes of choosing and buying lingerie involve identifications and dis-identifications of class, gender and sexuality, even though the garments themselves are rarely if ever worn in public.

Any "classical" theory of truth will satisfy tarski's criterion ("p" is true if and only if p), And the principle of bivalence (every proposition is either true or false). A non-Classical theory may be obtained by rejecting these principles: - in fact it is shown that rejection of the second entails rejection of the first. If the resulting non-Classical theory is formalized, A system structurally isomorphic to either s4 or s5 is obtained. An attempt is made to show that the (...) essential insights of intuitionist logic may be preserved if we replace their complex and in many respects "unintuitive" propositional logic by a theory of truth which is non-Classical in the sense described above.

The thesis of 3D/4D equivalence states that every three-dimensional description of the world is translatable without remainder into a four-dimensional description, and vice versa. In representing an object in 3D or in 4D terms we are giving alternative descriptions of one and the same thing, and debates over whether the ontology of the physical world is "really" 3D or 4D are pointless. The twins paradox is shown to rest, in relativistic 4D geometry, on a reversed law of triangle inequality. But (...) considering the twins as 3D beings who age through time, the paradox implies that time passes at different rates in different reference frames, and therefore that the concept of a single global or Absolute time is unsustainable.

In his paper ‘‘Bad luck once again’’ Neil Levy attacks our proof of the consistency of libertarianism by reiterating a time-worn compatibilist complaint.1 This is, that what is not determined must be due to chance. If A has a choice of X or Y, neither X nor Y being causally determined, then if A chooses X it can only be by chance, never for a reason. The only ‘‘reason’’ that could explain the choice of X over Y would have to (...) be a causally sufficient reason, which would rule out A’s having a genuine choice in the first place. Either X is causally necessitated or X is realized by sheer luck. But that these are the only alternatives is untrue. The exercise of deliberative reason opens the way between the Scylla of causal necessitation and the Charybdis of chance, as we shall try to make clear. The central core of Levy’s argument is that any attempt to give a reasons-based explanation of a contrastive fact must fail. A contrastive fact is a fact of the kind ‘‘Jane decides to vacation in Hawaii rather than Colorado,’’ or ‘‘Jane assigns a greater weight to surfing that to white-water rafting.’’ In the last three paragraphs of his paper Levy argues that Jane’s assigning more weight to surfing than to rafting cannot be a reasons-based assignment, because, as he puts it, ‘‘the reasons that would explain the weighting are the weighted reasons themselves.’’ Similarly, prior to making her Hawaii⁄ Colorado decision, Jane has..

This article examines how 20 female college students who identified as members of the Church of Jesus Christ of Latter-day Saints negotiated its gender ideology to legitimate their educational goals. The young LDS women creatively employed equality, professionalism, and essentialist discourses to craft a coherent identity as a “good LDS woman” that incorporated their pursuit of higher education. Beyond providing an in-depth look at how college-age LDS women “do gender,” the analysis informs our understanding of the persistence of women's participation (...) in patriarchal religious institutions, the process of women's resistance, and women's role in the negotiated process of hegemony. The authors argue that while women embrace the LDS gender ideology of womanhood, their pursuit of higher education is a form of resistance—embedded resistance—often neglected by scholars. The findings suggest the importance of nomos and meaning in understanding women's participation in and manipulation of patriarchal religious institutions. (shrink)

This paper argues that in order to understand West Indian economic underdevelopment, the saliency of the informal institutions that emerged during its colonial period and the effect these institutions have had on the emergence of a local entrepreneurial class can not be discounted. British colonial occupation, I contend, gave rise to two persistent informal institutions that have affected development: a belief in the ability and responsibility of government to direct the economy and pessimism regarding the possibility of entrepreneurial success. Relying (...) on Schumpeter’s discussion of the importance of entrepreneurs to economic development and North’s work on informal institutions, I examine how the poverty of entrepreneurs in the region and the cultures of corruption, privilege and intervention that evolved as a result of the region’s colonial experiences have hampered past efforts at development.Cet article soutient qu’afin de comprendre le sous-développement économique des Caraïbes, il est important de ne pas négliger la prédominance des institutions informelles qui ont émergé durant la période coloniale et l’influence que ces institutions ont eue sur l’émergence d’une classe entrepreneuriale locale. L’occupation coloniale britannique, selon l’auteur, a donné naissance à deux institutions informelles persistantes qui ont affecté le développement : une conviction dans la capacité et la responsabilité du gouvernement à diriger l’économie et un pessimisme vis-à-vis de la possibilité de succès entrepreneuriaux. En se fondant sur la théorie Schumpeterienne sur le rôle de l’entrepreneur dans le développement économique et sur les travaux de North concernant les institutions informelles, l’auteur examine comment la rareté des entrepreneurs dans la région et la corruption, les privilèges et les interventions qui ont évolué en résultat des expériences coloniales de la région, ont entravé les efforts de développement dans le passé.

Friedrich A. Hayek argues that “equality of the general rules of law and conduct” is the only kind of equality compatible with liberty and, moreover, that attempting to pursue equality along any other dimension is likely to destroy liberty. For Hayek, then, as a social philosopher and political economist who was principally concerned with understanding and promoting liberal order, the question “What kind of equality?” has a straightforward answer. Equality before the law, perhaps equality of opportunity in a procedural sense, (...) is the equality that we should pursue, not material equality and certainly not equality of outcomes. One wonders, though, whether Hayek dismisses too quickly the more substantive forms of equality and, more importantly, whether we can achieve the liberal society that Hayek envisions without concerning ourselves with more than just the presence or absence of equality of the general rules of law and conduct. This essay will explore, criticize, and expand upon the way that Hayek makes use of equality in his conception of a free society. Specifically, we argue that Hayek may need a more substantive conception of equality than he is willing to deploy in order to arrive at the liberal society he hopes to bring about. (shrink)

David Lewis, following in the tradition of Broad, Quine and Goodman, says that change in an object X consists in X's being temporally extended and having qualitatively different temporal parts. Analogously, change in a spatially extended object such as a road consists in its having different spatial parts . The alternative to this view is that ordinary objects undergo temporal change in virtue of having different intrinsic non-relational properties at different times. They endure, remaining the same object throughout change, whereas (...) Lewis's temporally extended 4D objects perdure.It is impossible to come down on one side or the other of the endurance/perdurance debate without a clear and unambiguous understanding of what ‘endurance’ is. ‘Perdurance’ is clear enough. Every 4D object of non-zero temporal thickness perdures simply by having temporal extension, i.e. by having different temporal parts, or stages, at different times. But Lewis muddies the waters by giving a confused and ultimately untenable definition of endurance.His first step is to cover both perduring and enduring by offering the neutral word persist. ‘Let us say that something persists iff, somehow or other, it exists at various times’ . Something then perdures if it persists by having different temporal parts at different times, no one part being wholly present at more than one time. In contrast, a thing endures if it persists by being wholly present at more than one …. (shrink)

Improvements in computational hardware enabled by nanotechnology promise a dual revolution in coming decades: machines which are both more intelligent and more numerous than human beings. This possibility raises substantial concern over the moral nature of such intelligent machines. An analysis of the prospects involves at least two key philosophical issues.

Second, what is the moral nature of (...) a machine vis-a-vis a human: can a machine be a true moral agent, capable of real responsibility, possessed of rights and duties? If so, might a machine be a better moral agent than a human? (shrink)

The weighting is however rational, and entirely under Jane's control. This controlled, rational, indeterministic process shows that libertarianism is a consistent philosophical thesis. (shrink)

This volume critically explore and extend Hayek's Nobel Prize-winning work on knowledge and social interconnectedness from the disciplines of law, economics, philosophy, anthropology, political science, and history.

There is no such thing as a distinct economic, political, or social sphere--they are inextricably intertwined. Given the range of both Hayek's work and the contributing authors' perspectives, the range of topics covered (...) in this volume is extraordinarily wide, running the gamut from immigration, to white supremacy, to ancient agricultural practices, to the nature of what it means to be free.

We all make decisions, sometimes dozens in the course of a day. This paper is about what is involved in this activity. It's my contention that the ability to deliberate, to weigh different courses of action, and then to decide on one of them, is a distinctively human activity, or at least an activity which sets man and the higher animals apart from other creatures. It is as much decisio as ratio that constitutes the distinguishing mark of human beings. Homo (...) may not always be rationalis, but he is always decidens.The paper is about practical decision, although there is also another important kind of decision that I won't discuss, namely cognitive decision. The difference is roughly that which distinguishes the function of a jury from that of a judge, at least in jury trials. The jury's job is to arrive at an answer to the question: guilty or not guilty? This is a cognitive decision, a decision that, on the basis of the evidence, such-and-such is the case. The judge, apprized of the jury's cognitive decision, makes the practical decision to sentence the guilty party to 20 years. On some other occasion, I hope to be able to say something about cognitive decision, as well as about a third kind of decision named value decision. (shrink)

Relative to any point in time, how many possible futures are there? For example, it may rain tomorrow, or again it may not. So it would appear that relative to today, there are at least two possible futures, one involving rain tomorrow and the other not. Of course only one of these two future states of affairs will take place, and in that sense there is only one actual future, though there may be many possible futures. The only hypothesis under (...) which there is, for every instant in time, only one possible future, is the hypothesis of universal Laplacean determinism, and this hypothesis has had little to recommend it since the advent of quantum physics. Furthermore, although among the many possible futures relative to any given moment in time there is only one which will become actual, no distinguishing mark separates this one from its fellows at the given moment. So it would appear that what confronts the world at each moment in time is an undifferentiated multiplicity of possible futures. But this multiplicity, though at first sight admittedly frightening in its implications, may be put to good philosophical use: as will be seen it yields natural and convincing definitions of the notions of physical necessity and possibility. On the other hand, alternative definitions of these notions are obtainable which do not make use of the manifold of possible futures, and these also will be presented. The paper will be in two parts, the first dealing with the concepts of physical possibility and necessity, and the second presenting a formal calculus of necessary and sufficient conditions in which the physical modalities find their place.
