A number of philosophers argue for a Two-Tier View: that there is some difference between individual-affecting and non-individual-affecting choices. But it is challenging to know the degree of moral difference, and to determine for some cases into which category they fall. I refer to this as the “Two Tier Problem.” In this paper, I develop and defend a “Two-Tier Deontic View.” On that view, the higher tier applies to a subset of individual-affecting cases. We have stronger reason to bring about (...) an individual-affecting rather than a non-individual-affecting benefit, but only in cases where we have agent-relative duties to the individuals so affected. In other cases (and I argue that this applies to most policy decisions affecting reproduction) there is no moral difference between individual- and non-individual-affecting choices. (shrink)

I describe a gauge-independent approach to the relativistic two-body bound state and scattering problems in quantum field theory. The basic tool is an ordinary three-dimensional equation involving a potential operator V which gets contributions from both irreducible and reducible diagrams. In QED the resultant V is independent of the choice of covariant gauge used for the photon propagator, unlike the kernel in the Bethe–Salpeter equation. As an illustration, a problem concerning spin-independent level shifts in two-body bound states is (...) analyzed. (shrink)

Testimonial accounts of mathematical problem choice typically rely on intrinsic constraints. They focus on the worth of the problem and feelings of beauty. These are often developed as both descriptive and normative constraints on problem choice. In this paper, I aim to add an extrinsic constraint of no less importance: the assurance of contact of minds with a desired audience. A number of elements for the relationship between mathematician and his audience make up this contact. This constraint stems (...) from the mathematician’s role as an arguer, as one of the pre-requisites to argumentation is contact of minds. I examine two exceptional cases which fail to be explained by intrinsic constraints on motivation and posit how this contact could influence usual cases. While not the only constraint or drive in problem choice, establishing contact of minds plays an important role worth further examination. (shrink)

The two-electron atom is the simplest nontrivial quantum system not amenable to exact solutions. Today, its relevance in the development of quantum mechanics and its pedagogical value within the realm of atomic physics are widely recognized. In this work, an historical review of the known different methods and results devised to study such a problem is presented, with an emphasis to the calculations of the ground state energy of helium. Then we discuss several, related, unpublished results obtained around the same (...) years by Ettore Majorana, which remained unknown till recent times. Among them a general variant of the variational method appears to be particularly interesting, even for current research in atomic and nuclear physics: it takes directly into account, already in the trial wavefunction, the action of the full Hamiltonian operator of a given quantum system. Further relevant contributions, specialized to the two-electron problem, include the introduction of the remarkable concept of an effective nuclear charge different for the two electrons (thus generalizing previous known results) and an application of the perturbative method, where the atomic number Z was treated effectively as a continuous variable. Finally a survey of results, relevant mainly for pedagogical reasons, is given; in particular we focus on simple broad range estimates of the helium ionization potential, obtained by suitable choices for the wavefunction, as well as on a simple alternative to Hylleraas’ method, which led Majorana to first order calculations comparable in accuracy with well-known order 11 results derived, in turn, by Hylleraas.

This paper studies a decision maker who tackles a choice problem by selecting a subset of (at most) two alternatives which he will consider further in the second stage of his deliberation. We focus on the first stage where he chooses the delebration set. We axiomatize three types of procedures: (i) The top two: the decision maker has in mind an ordering and chooses the two maximal alternatives. (ii) The two extremes: the decision maker has in mind an ordering (...) and chooses the maximal and the minimal alternatives. (iii) The top and the top: the decision maker has in mind two orderings and he chooses the maximal elements. (shrink)

Numerous authors indicate that the influence of academic education extends beyond the growth of specialized knowledge gained by the graduates. Scholars are trying to identify and examine the potential impact of higher learning on students’ attitudes and choices. One of the dimensions considered by the researchers is the effect of university training on students’ moral choices. Our paper attempts to identify differences between the students’ declared moral choices and their majors (fields of studies). Working with a sample of university students (...) of Economics and Sociology (N = 181), and using three variants of the Trolley Problem, the subjects’ responses are used to identify the similarities and differences between their choices. The participants were asked to respond to three hypothetical situations regarding a runaway trolley. Their decision in the first scenario could save a person’s life or let her be run over by the trolley. In the second scenario, their decision could either let one person die and save five lives or save one life and let five people be killed. These two scenarios required pulling a lever to switch the trolley from one track to another. The third scenario requires pushing an obese person in front of the runaway trolley to stop it from killing five persons. As expected, we found a significant difference between the two groups (the economists and the sociologists) in the case of our third scenario, however, we found no evidence supporting the indoctrination hypothesis. We conclude that the existing differences between the choices made by the future economists and sociologists may support the preselection hypothesis. (shrink)

We examined how children's strategy choices in solving complex subtraction problems are related to grade and to variations in problem complexity. In two studies, third- and fifth-grade children (N≈160 each study) solved multi-digit subtraction problems (e.g., 34–18) and described their solution strategies. In the first experiment, strategy selection was investigated by means of a free-choice paradigm, whereas in the second study a discrete-choice approach was implemented. In both experiments, analyses of strategy repertoire indicated that third-grade children (...) were more likely to report less-efficient strategies (i.e., counting) and relied more on the right-to-left solution algorithm compared to fifth-grade children who more often used efficient memory-based retrieval and conceptually-based left-to-right (i.e., decomposition) strategies. Nevertheless, all strategies were reported or selected by both older and younger children and strategy use varied with problem complexity and presentation format for both age groups. These results supported the overlapping waves model of strategy development and provide detailed information about patterns of strategy choice on complex subtraction problems. (shrink)

Throughout the world, female students are less likely than males to take advanced physics courses. This mixed-methods study uses a concurrent, nested design to study an online homework intervention designed to address choice and achievement. A choice of three different contexts (biological, sports, and traditional) were offered to students for each physics problem, intending to stimulate females’ interest and enhance achievement. Informed by aspects of Artino’s social-cognitive model of academic motivation and emotion, we investigated: Which context of physics (...) problems do males and females select?; What explanations do students give for their choices?; Are there differences in the achievement of males and females?; and Is there a relationship between student achievement and the context selected? Fifty-two high school physics students from five U.S. states participated. Data included pre and post Force Concept Inventory scores, homework context choices and achievement, and rationales for choices. Findings indicate that females were most likely to select biology contexts; males, traditional. All students made more attempts on video questions over word questions, although females did not score as well. For all questions, students generally persisted until they answered them correctly, with females taking fewer attempts on problems. Context choice was mostly driven by interest, for males, and perceptions of difficulty level for females; however, rationales were indistinguishable by gender. On their first homework question attempt, females scored significantly better than the males. Initially, males had significantly higher FCI scores; post homework intervention, females increased their mean scores significantly on the FCI, erasing the initial gender gap, with no growth nor decline in males’ scores. Females with FCI growth were equally as likely to choose biology contexts as traditional contexts; males were more likely to choose biology contexts. Findings from this study suggest that modest changes to homework problems that provide choice and make the physics problems more contextually interesting - even without changes in classroom instruction - could increase interest and motivation students and increase achievement for both male and female students. Recommendations will be discussed. (shrink)

Making adaptive choices between solution strategies is a central element of contemporary mathematics education. However, previous studies signal that students make suboptimal choices between mental and written strategies to solve division problems. In particular, some students of a lower math ability level appear inclined to use mental strategies that lead to lower performance. The current study uses a pretest-training-posttest design to investigate the extent to which these students’ choices for written strategies and performance may be increased. Sixth graders of (...) below-average mathematics level (N = 147) participated in one of two training conditions: an explicit-scaffolding training designed to promote writing down calculations or a practice-only training where strategy use was not explicitly targeted. Written strategy choices and performance increased considerably from pretest to posttest for students in both training conditions, but not in different amounts. Exploratory results suggest that students’ strategy choices may also be affected by their attitudes and beliefs and the sociocultural context regarding strategy use. (shrink)

This inquiry focuses on the problem of human freedom in the thought of Augustine and two of his early critics, John Cassian and Faustus of Riez. Two issues are of primary importance: the issue concerning the nature of free choice of will, and the issue concerning how free choice of will is to be reconciled with divine election. These issues arise as a result of a change that occurred in Augustine's thinking on human freedom in 396, the year (...) that he grasped the true significance of Paul's doctrine of divine election. To Augustine that doctrine entailed that the will's movement towards the Good was only possible if divine Good Itself worked within the fallen will to make it good. Cassian and Faustus, however, questioned how Augustine could affirm the reality of free choice of will when he insisted that the fallen moral agent lacked the natural ability to do good. ;In order to come to terms with this dilemma, this inquiry views Augustine's later doctrine of human freedom as a form of classical Christian compatibilism. Beginning with H. A. Wolfson's observation that in the Pelagian Controversy Augustine Christianized the pagan Stoic doctrine of fate, the study seeks to develop the implications of this observation in the context of the semi-Augustinian Controversy . Thus it attempts to carry out a task that Wolfson himself had intended to undertake but had never in fact been able to accomplish. ;In keeping with this objective, the inquiry develops Wolfson's claim by situating Augustine's response to the semi-Augustinians against the background of two key texts: Cicero's De fato and Augustine's De civitate dei . A careful study of these texts indicates not only a remarkable similarity between Chrysippus' and Augustine's solution to the problem of human freedom but also Augustine's own awareness of his indebtedness to the Stoics. With this background in mind, the inquiry proceeds, initially, to unravel Augustine's doctrine of human freedom and, subsequently, to view it in relation to Cassian's and Faustus' doctrine of human freedom. After drawing out the implications of these three doctrines of human freedom, a concluding chapter calls attention to the fact that Stoicism exerted a much more pervasive influence on the development of Augustine's doctrine of human freedom than has hitherto been suspected.

There has been a significant interest in the recent literature in developing a solution to the problem of theory choice which is both normative and descriptive, but agent-based rather than rule-based, originating from Pierre Duhem’s notion of ‘good sense’. In this paper we present the properties Duhem attributes to good sense in different contexts, before examining its current reconstructions advanced in the literature and their limitations. We propose an alternative account of good sense, seen as promoting social consensus in (...) science, and show that it is superior to its rivals in two respects: it is more faithful to Duhemian good sense, and it cashes out the effect that virtues have on scientific progress. We then defend the social consensus account against objections that highlight the positive role of diversity and division of labour in science. (shrink)

In the two-envelope problem, one is offered a choice between two envelopes, one containing twice as much money as the other. After seeing the contents of the chosen envelope, the chooser is offered the opportunity to make an exchange for the other envelope. However, it appears to be advantageous to switch, regardless of what is observed in the chosen envelope. This problem has an extensive literature with connections to probability and decision theory. The literature is roughly divided between those (...) that attempt to explain what is flawed in arguments for the advantage of switching and those that attempt to explain when such arguments can be correct if counterintuitive. We observe that arguments in the literature of the two-envelope problem that the problem is paradoxical are not supported by the probability distributions meant to illustrate the paradoxical nature. To correct this, we present a distribution that does support the usual arguments. Aside from questions about the interpretation of variables, algebraic ambiguity, modal confusions and the like, most of the interesting aspects of the two-envelope problem are assumed to require probability distributions on an infinite space. Our next main contribution is to show that the same counterintuitive arguments can be reflected in finite versions of the problem; thus they do not inherently require reasoning about infinite values. A topological representation of the problem is presented that captures both finite and infinite cases, explicating intuitions underlying the arguments both that there is an advantage to switching and that there is not.

Solving problems with insight culminates in an “Aha! moment”: a feeling of confidence and pleasure. In daily life, insights are often followed by important decisions, such as deciding what to do with a new idea. Here, we investigated whether having an Aha! moment affects subsequent decision-making. Because Aha! moments tend to elicit positive affect, which is generally associated with an increased risk-taking tendency, we hypothesized that people would favor a monetary payout with more upside despite greater uncertainty after solving (...) a problem with insight. Participants were asked to solve verbal puzzles and report whether they solved them with insight or without insight. After each puzzle, they chose between two bonuses: a fixed payout or a risk payout with 50% chance of receiving a high or a low payout. Participants were more likely to choose the risk payout after they solved with insight compared to without, suggesting a temporarily higher risk preference. The study provided pre­liminary evidence of a carryover effect - the impact of an Aha! moment on the subsequent risk choice - that can have implications in everyday decision-making. (shrink)

Kuhn’s famous thesis that there is ‘no unique algorithm’ for choosing between rival scientific theories is analysed using the machinery of social choice theory. It is shown that the problem of theory choice as posed by Kuhn is formally identical to a standard social choice problem. This suggests that analogues of well-known results from the social choice literature, such as Arrow’s impossibility theorem, may apply to theory choice. If an analogue of Arrow’s theorem does hold (...) for theory choice this would refute Kuhn’s thesis, but it would also pose a threat to the rationality of science, a threat that is if anything more worrying than that posed by Kuhn. Various possible ‘escape routes’ from Arrow’s impossibility result are examined, in particular Amartya Sen’s idea of ‘enriching the informational basis’. It is shown that Sen’s idea can be applied to the problem of theory choice in science. This in turn sheds light on two well-known approaches to inductive inference in philosophy of science: Bayesianism and statistical model selection. (shrink)

The problem of intertemporal choice arises when outcomes are received in different moments of time. This paper presents an axiomatic model of intertemporal choice when consumption in the previous moment of time contributes to utility evaluation of consumption in the current moment. This model generalizes classic discounted utility theory (also known as constant or exponential discounting) in two ways. First, in every moment of time, a decision maker derives utility not only from current consumption but also from “residual” (...) consumption in the previous moment of time. Second, these utilities are discounted with weights that are essentially a quasi-hyperbolic discounting function. The paper presents an application of the proposed model to the problem of optimal consumption and savings given a fixed income (wealth). When a decision maker derives satisfaction from both instantaneous consumption as well as a share of consumption in the previous moment of time, optimal consumption path is cyclic—periods of relatively high consumption are interchanged with periods of relatively low consumption. These cycles decay over time. Asymptotically, the consumption path exhibits conventional properties (constant, increasing or decreasing over time when a gross interest rate multiplied by discount factor is correspondingly equal to, greater than, or less than one).

Newcomb’s problem involves a decision-maker faced with a choice and a predictor forecasting this choice. The agents’ interaction seems to generate a choice dilemma once the decision-maker seeks to apply two basic principles of rational choice theory : maximize expected utility ; adopt the dominant strategy. We review unsuccessful attempts at pacifying the dilemma by excluding Newcomb’s problem as an RCT-application, by restricting MEU and ADS, and by allowing for backward causation. A probability approach shows that (...) Newcomb’s original problem-formulation lacks causal information. This makes it impossible to specify the probability structure of Newcomb’s univocally. Once missing information is added, Newcomb’s problem and RCT re-align, thus explaining Newcomb’s problem as a seeming dilemma. Building on Wolpert and Benford :1637–1646, 2013), we supply additional details and offer a crucial correction to their formal proof. (shrink)

This article seeks to contribute to the discussion on the nature of choice in virtue theory. If several different actions are available to the virtuous agent, they are also likely to vary in their degree of virtue, at least in some situations. Yet, it is widely agreed that once an action is recognised as virtuous there is no higher level of virtue. In this paper we discuss how the virtue theorist could accommodate both these seemingly conflicting ideas. We discuss (...) this issue from a modern Aristotelian perspective, as opposed to a purely exegetic one. We propose a way of resolving what seems to be a major clash between two central features of virtue ethics. Our proposal is based on the notion of parity, a concept which recently has received considerable attention in the literature on axiology. Briefly put, two alternatives are on a par (or are ‘roughly equal’) if they are comparable, although it is not the case that one is better than the other, nor that they are equally good. The advantages of applying the concept of parity to our problem are twofold. Firstly, it sheds new light on the account of choice in virtue theory. Secondly, some of the criticisms that have been mounted against the possibility of parity can be countered by considering the notion of choice from a virtue theory perspective. (shrink)

This paper concerns local yet systematic problems of contrastive underdetermination of model choice in cognitive neuroscience debates about the so-called two visual systems hypothesis. The underdetermination problem is systematically generated by the way certain assumptions about the representationalist nature of computation are translated into experimental practice. The problem is that behavioural data underdetermine the choice between competing representational models. In this paper, I diagnose how these assumptions generate underdetermination problems in the choice between competing functional (...) models of perception–action. Using the tools of philosophy of science, I describe the type of underdetermination and sketch a possible cure. (shrink)

A question that has been largely overlooked by philosophers of religion is how God would be able to effect a rational choice between two worlds of unsurpassable goodness. To answer this question, I draw a parallel with the paradigm cases of indifferent choice, including Buridan's ass, and argue that such cases can be satisfactorily resolved provided that the protagonists employ what Otto Neurath calls an ‘auxiliary motive’. I supply rational grounds for the employment of such a motive, and (...) then argue against the views of Leibniz and Nicholas Rescher to show that this solution would also work for God. (shrink)

We discuss several features of coherent choice functions—where the admissible options in a decision problem are exactly those that maximize expected utility for some probability/utility pair in fixed set S of probability/utility pairs. In this paper we consider, primarily, normal form decision problems under uncertainty—where only the probability component of S is indeterminate and utility for two privileged outcomes is determinate. Coherent choice distinguishes between each pair of sets of probabilities regardless the “shape” or “connectedness” of the (...) sets of probabilities. We axiomatize the theory of choice functions and show these axioms are necessary for coherence. The axioms are sufficient for coherence using a set of probability/almost-state-independent utility pairs. We give sufficient conditions when a choice function satisfying our axioms is represented by a set of probability/state-independent utility pairs with a common utility. (shrink)

In this paper I provide a critique of a set of assumptions relating to agency, choice and the legitimacy of actions impacting health that can be seen in some approaches to health promotion. After a brief discussion about the definition of health promotion, I outline two contrasting approaches to this area of health care practice. The first is focused on the provision of information and the second is concerned with seeking to change people’s preferences in a particular way. It (...) has been argued by a number of critics of health promotion that only the first approach is ethical, as it is for individuals to make their own lifestyle choices and adopt their own conception of the good life. I argue against this ‘information’ approach to health promotion on two grounds. First, I suggest that given the aims of health promotion, the provision of information is, as a matter of fact, of limited effectiveness in achieving these aims. Second, I argue that we have good reasons to question the appropriateness of respecting many of the preferences that individuals happen to have, given the origins and quality of such preferences. I then go on to argue, that by contrast we have good reasons to focus on changing at least some of the preferences that people have related to their lifestyle choices. This involves a commitment to both paternalism and a defence of a certain conception of the good life, but both can be defended. I use the example of potential responses to the growing problem of obesity to illustrate my argument, arguing that only policy that, at least sometimes, aims at preference change will be both effective and ethical.

David Lewis argued that Newcomb’s Problem and the Prisoner’s Dilemma are “one and the same problem” or, to be more precise, that the Prisoner’s Dilemma is nothing else than “two Newcomb problems side by side” (Lewis Philosophy and Public Affairs 8:235–240, 1979 : 235). It has been objected that his argument fails to take into account certain epistemic asymmetries which undermine the one-problem thesis. Sobel ( 1985 ) acknowledges that many tokens satisfy the structural requirements of both problems, (...) while questioning the generality of the thesis. Bermúdez (Analysis 73:423–429, 2013 ), on the other hand, argues that there is a deeper structural conflict between the two problems in the sense that the epistemic requirements that give Newcomb’s Problem its force are precisely those that prevent it from being a Prisoner’s Dilemma. I argue that the epistemic asymmetry objections raised by Sobel and Bermúdez fail to undermine the one-problem thesis. A different type of objection raised by Bermúdez, one which relies on the contrast between parametric and strategic choices, fares no better. Although NP is a problem that has been primarily studied for its implications to decision theory, it contains enough game theoretic elements to justify the claim that a juxtaposition of two such problems can be thought of as a strategic game.

A recent paper by David Levy focuses on “utility enhancing consumption constraints.” Levy concludes by noting that his analysis stays within standard utility maximizing theory, in contrast to my analysis of rule-governed behavior which allows imperfect decisions that don't always maximize utility. I wish to show how our two theories can be integrated, thereby representing complementary, rather than conflicting, explanations. In the process, I argue that imperfect decisions are an essential factor in the stability of any rule that constrains freedom (...) of choice. I also briefly discuss certain intrinsic problems with achieving “self-stabilizing” rules applied to moral teachings. (shrink)

FR. THOMAS HUGHSON, S.J. Pontificial Biblical Institute,!erusalem; Marquette University, Milwaukee, Wisconsin Choice: The Essential Element in Human Action. By ALAN DoNAGAN. Studies in Philosophical Psychology, R. F. Holland, ed. London and New York: Routledge and Kegan Paul, 1987. Pp. x + 197. $29.95 (cloth). Readers of Donagan expecting a book in the style of The Theory of Morality will be surprised; Choice: The Essential Element in Human Action is far more compact and demanding. In setting out to support his thesis that the "propositional attitudes" (the term is taken from Russell) of beliefs and wishes explain choices which, in turn, explain human actions, the author considers a plethora of views and objections of both contemporary and traditional philosophers: Gilbert Ryle-whose Concept of Mind Donagan considers a classic of analytic Aristotelianism -Roderick Chisholm, Donald Davidson, Anthony Kenny, John Searle, Alvin Goldman, Elizabeth Anscombe, Bertrand Russell, Plato, Aristotle, Aquinas, Wittgenstein, Quine, and Frege. At times the reader may wish that fewer theorists were appealed to, or perhaps that his or her familiarity with the views referred to were more extensive, or at least that (although not in the case of Frege) they were explicated in more detail. Further explication, however, could obscure hopelessly the line of reasoning of the author. While he appears to wish to give credit every place it is due, he also wishes to clarify the genesis of significant objections to be met by a defensible action theory. Happily, Donagan himself provides an overview of his project, which he calls a " Plan for an Investigation of Human Action on Socratic Lines." This is proffered in chapter one after the author has discussed the " Socratic tradition in the theory of human action " and the question "Should the Socratic tmdition be jettisoned as folk psychology?" BOOK REVIEWS 161 As these sections provide the foundation for Donagan's thesis, they are briefly summarized here. Considering both Aristotle and the " mediaeval Aristotelian " Aquinas to be in the Socratic tradition, Donagan emphasizes Aristotle's role in distinguishing human from animal action. Possibilities for acting are represented in the human intellect in propositions, toward which one can take various attitudes. Those philosophers who hold that such propositional attitudes cannot explain human action are challenged. Donagan then takes on those cognitive scientists who reject as " stagnant " and rooted in folk beliefs the Socratic theory of action. He rather impressively presents the problems involved in admitting, as do the " scientific psychologists," the practicality of employing the notion of propositional attitudes in history and natural sciences (which seem to exist in a context of history), while at the same time actually :rejecting the existence of such attitudes and hence their theoretical validity. Indeed, Donagan brings home the point that it is simply incon· sistent to hold both that there are no beliefs and that the belief that there are beliefs underlies a stagnant research program. Having thus sustained his position :regarding propositional attitudes in general, Donagan summarizes, chapter by chapter, his "contem· po:rary Socratic " plan for examining the actions of rational animals. It will be helpful to sketch this program, filling in crucial portions. In chapter two the author contends that bodily or mental actions are events that are individuals insofar as they are " changes or persistences in states of continuing individual objects" (p. 38). Propositional attitudes are states, but their arising and persistence in being as energeiai are events that explain,actions. Building on Aristotle's teaching and that of his mediaeval successors, in chapter three Donagan argues that beliefs and wishes, or the cognitive and appetitive propositional at· titudes, explain choices which in turn explain actions. In chapter four Donagan elucidates Durnmett's :revision of the Fregeau semantical theory, which he opts... (shrink)

A scientifically proven method to overcome obstacles and make choices that lead us closer to our goals. WITH A FOREWORD BY MARTINA NAVRATILOVA What do weight gain, poor employee engagement, and climate change all have in common? All three are persistent problems for which solutions are known and readily available. Yet, on an individual and collective level, we continually make choices that lead us not closer to but further away from our stated objectives. Whether we choose the burger and (...) fries over the salad, top-down management over collaboration, or leniency over rigor in combatting climate change, it all comes down to the same thing. The Choice Point. The moment at which we each choose to take an action that we know will undermine our success, but we do it anyway. The Choice Point explains how we experience thousands of thoughts every day: 80 percent are negative, while only 5 percent are new thoughts. We make most of our decisions within two seconds, using mental autopilot systems that we've built through years of experiences, and some of our thoughts (like quitting during a challenge) can compromise our goals. But there's a strategy to change this: Functional Imagery Training (FIT). FIT teaches us how to pick the thoughts that deserve our attention, and how to stop the other, negative thoughts from impacting our actions. Through FIT, we can pause decisions that would typically conflict with our goals, lengthen our Choice Point, and go from passenger to driver of our own minds. Initially developed in 2005 by academics in the UK and Australia, with formal principles emerging through research in 2018, FIT blends motivational interviewing with imagery into a user-friendly model so we can learn, adapt, and adjust our behavior to go beyond what we think is possible.

We study the computational content of the Brouwer Fixed Point Theorem in the Weihrauch lattice. Connected choice is the operation that finds a point in a non-empty connected closed set given by negative information. One of our main results is that for any fixed dimension the Brouwer Fixed Point Theorem of that dimension is computably equivalent to connected choice of the Euclidean unit cube of the same dimension. Another main result is that connected choice is complete for (...) dimension greater than or equal to two in the sense that it is computably equivalent to Weak Kőnig’s Lemma. While we can present two independent proofs for dimension three and upward that are either based on a simple geometric construction or a combinatorial argument, the proof for dimension two is based on a more involved inverse limit construction. The connected choice operation in dimension one is known to be equivalent to the Intermediate Value Theorem; we prove that this problem is not idempotent in contrast to the case of dimension two and upward. We also prove that Lipschitz continuity with Lipschitz constants strictly larger than one does not simplify finding fixed points. Finally, we prove that finding a connectedness component of a closed subset of the Euclidean unit cube of any dimension greater than or equal to one is equivalent to Weak Kőnig’s Lemma. In order to describe these results, we introduce a representation of closed subsets of the unit cube by trees of rational complexes. (shrink)

Disjunctions in the scope of possibility modals give rise to a conjunctive inference, generally referred to as ‘free choice.’ For example, Emma can take Spanish or Calculus suggests that Emma can take Spanish and can take Calculus. This inference is not valid on standard semantics for modals in combination with a Boolean semantics for disjunction. Hence free choice has sparked a whole industry of theories in philosophy of language and semantics. This paper investigates free choice in sentences (...) involving a non-monotonic modified numeral, under which we embed a possibility modal scoping over disjunction. One example is Exactly one student can take Spanish or Calculus. As we point out, the presence of certain readings of these sentences is a key test for a prominent approach, which analyzes free choice as a kind of scalar implicature. We report on two experiments investigating the readings of such sentences, using an inferential task. Our results are challenging for the implicature approach. We sketch two possible solutions within this approach, either adopting a different recent implicature algorithm, or exploring a different meaning for modified numerals with exactly. Both of them suffer from a variety of problems. We then discuss a third solution, which exploits a recent account of free choice based on homogeneity. This approach can account for our results, in combination with plausible assumptions about homogeneity projection, though it too has open issues with related cases. Regardless of which solution is chosen, non-monotonic contexts turn out to be an important test case for theories of free choice, implicature, and modified numerals. (shrink)

The main subject of this paper is the two significant problems of environmental ethics which are ecofascism and speciesism. This scrutiny offers an evaluative perspective on the main problems of environmental ethics and is conducted with this aim. Most of the environmental philosophers, all the difficulties notwithstanding, try to find a middle way in the ecofascism-speciesism continuum and their theories get closer to one or the other edge of this continuum. John Baird Callicott is one of the environmental (...) philosophers who struggle with this issue when his theory indicates one of the problems or gets closer to one of the edges, he tries to find a new way to go. There are six turns in Callicott's philosophy starting with strong holism due to accepting Leopold's land ethic as a basis. Then, he constructed a theory that pushes him closer to the speciesist edge, and finally, he found a way out from these fatal consequences. However, all the environmental philosophers face the same problems in their journey although they are either holists or individualists in the end. In constructing a holistic environmental ethical theory, for instance, they may be in ecofascism difficulty because holism requires man to be an ordinary member of the biotic community as seen in the first turn. Or, establishing a special place for humankind to ditch the ecofascism crisis may cause another equally important crisis, namely, speciesism (see the third turn). Some philosophers prefer to be closer to one of the edges always being on guard against the other. Some others, like Callicott, try to find a middle way equally far from the edges. However, this choice is no easier. Selecting to be a member of both the human community and biotic community brings different problems, such as ranking problems between the duties and obligations toward the communities and their members, i.e. a challenge to decision-making processes. For such problems, they come up with some principles or rules like second-order principles (SOPs) as Callicott did (in the fifth turn). But, these rules or principles are not sufficient enough to solve the ranking problems of setting priorities among our duties to members of both communities, either. Thus, either there is a need for more regulations and rules, or these two communities should be separated in a different dimension and gathered at another level. The second choice is preferred by Callicott and used as a solution to the main problem: constructing an environmental ethical theory that involves whole nature with its members and which is free from two essential problems (see the sixth turn). As a final point, Callicott's last theory seems to point to the conclusion that an environmental ethical theory is possible without falling into the ecofascism and speciesism traps, i.e. his last stand can facilitate the attainment of the main subject of this essay.

"Ethical Choices in Contemporary Medicine" jettisons the standard medical ethics models of "rights" language and shows how the bioethical problems that receive attention from the media and the public are related to and are explicable in terms of the epistemological foundations of science and medicine. These epistemological concerns include how medical knowledge is established , how medical protocols are administered , how medical certainty is evaluated and medical responsibility is framed , and how medical knowledge is transmitted and how (...) medical care is allocated . The book examines the present predicaments of medicine within a broad cultural context and suggests that rational discourse and parochial ethical dialogue may be futile in the face of competing and incommensurable frameworks and agendas, attitudes and wishes. The authors show that, in the postmodern age, two interrelated issues surface when it comes to medicine. On the one hand, there is a strong critique of science and the privileges associated with the scientific discourse and, on the other, there is still a deep-seated quest for certainty in all medical matters.

Life Choices is the second edition of a collection of “some of the very best articles published in the Hastings Center Report over the last 28 years”. The collection has two main aims: to provide a challenging text for classrooms and to serve as a testimony to the achievements of the Hastings Center. The first edition was published in 1994 to mark the 25th anniversary of the Hastings Center's foundation. The Hastings Center, based in New York state, is the oldest (...) independent, non-partisan interdisciplinary research institute of its kind in the world and has become a highly influential organisation. The center's mission is the study of the moral problems that arise out of the rapid advances in medicine and biology, and collaboration with policy makers, both in the private and public sphere, to aid the analysis of the ethical dimension of their work. The collection is organised around themes which reflect the center's research …. (shrink)

A central problem of democracy is the aggregation of divergent individual inputs into overall collective decisions. Social-choice-theoretic impossibility results famously demonstrate the intractability of a large class of such aggregation problems. This paper develops a taxonomy of two concepts of agreement, agreement at a substantive level and agreement at a meta-level, and discusses the escape-routes these concepts open up from the impossibility problems of social choice. Specifically, two contexts of democratic aggregation are addressed: first, the familiar (...) context of preferences, and second, the largely unexplored context of sets of judgments over multiple interconnected propositions. Drawing on some recent developments in social choice theory and democratic theory, I will defend the view that, when agreement is conceptualized in democratic theory and when it is sought in democratic practice, more emphasis should be placed on agreement at a meta-level than is commonly done. Finally, I will address the more general question to what extent it is acceptable for the stability of institutions for democratic aggregation to be dependent on specific empirical contingencies.

Canada is six years into a new era of legalized medical assistance in dying (MAiD). The law continues to evolve, following a pattern in which Canadian courts rule that legal restrictions on eligibility for MAiD are unconstitutional and Parliament responds by gradually expanding eligibility for MAiD. The central tension underlying this dialogue between courts and government has focused on two conceptions of how to best promote and protect the interests of people who are vulnerable by virtue of intolerable and irremediable (...) suffering due to an illness, disease, or disability. Do we, as a society, have a duty to protect vulnerable people from seeking certain medical procedures that are contrary to their interests, as those are perceived by others? Or do we have a duty to uphold their rights to autonomy, including the right to make choices within a range that may be constrained by many factors, some of which may be socially unjust? This is a recurrent problem in bioethics and medical law, which we explore through the lens of how Canadian courts and Parliament have grappled with defining eligibility for MAiD. (shrink)

In this paper, I examine the conflicts between autonomy and justice. The problem of justice in healthcare concerns both micro-allocation and macro-allocation. The latter has to do with distributive justice: who should get what healthcare resources at whose expense. The current debate about healthcare reform brings up two competing models of distributive justice from political philosophy. The libertarian theory holds to the ideal of individual responsibility and choice, viewing taxation for the purpose of providing goods to those who cannot (...) afford them as a form of unjustified coercion. The liberal theory holds that society should ensure that all members are provided with basic goods that correct for inequalities that deprive them of human dignity. Even though both theories value individual choice, these theories provide opposing answers to the question of whether taxes should be collected and used for the purpose of ensuring universal access to healthcare. In my paper, I show that neither theory can respect patient choice in healthcare and achieve distributive justice. Libertarians ignore the realities of the healthcare system and why a free market where patients choose and pay for what they want cannot exist. Liberals face the problem that the choices that patients make can lead to over-consumption of healthcare at the expense of other goods important to society. (shrink)

This article resolves some difficulties with Aristotle's discussion of the choice-worthy (haireton). Nicomachean Ethics I posits goods that are choice-worthy for themselves and for something else, but Nicomachean Ethics X appears to present being choice-worthy for itself as mutually exclusive with being choice-worthy for something else; moreover, Nicomachean Ethics X seems to claim that action is choice-worthy for itself and, therefore, not choice-worthy for something else but also seems to claim that action is (...) class='Hi'>choice-worthy for something else and, therefore, not choice-worthy for itself. As for the latter problem internal to Nicomachean Ethics X, I argue that Aristotle is ultimately committed to the idea that action is choice-worthy for something else. As for the problem between Nicomachean Ethics I and X, I argue that Nicomachean Ethics X only claims something admitted by Nicomachean Ethics I: being choice-worthy for something else is mutually exclusive with being choice-worthy only for itself.

Learning to solve a class of problems can be characterized as a search through a space of hypotheses about the rules for solving these problems. A series of four experiments studied how different learning conditions affected the search among hypotheses about the solution rule for a simple computational problem. Experiment 1 showed that a problem property such as computational difficulty of the rules biased the search process and so affected learning. Experiment 2 examined the impact of examples as (...) instructional tools and found that their effectiveness was determined by whether they uniquely pointed to the correct rule. Experiment 3 compared verbal directions with examples and found that both could guide search. The final experiment tried to improve learning by using more explicit verbal directions or by adding scaffolding to the example. While both manipulations improved learning, learning still took the form of a search through a hypothesis space of possible rules. We describe a model that embodies two assumptions: the instruction can bias the rules participants hypothesize rather than directly be encoded into a rule; participants do not have memory for past wrong hypotheses and are likely to retry them. These assumptions are realized in a Markov model that fits all the data by estimating two sets of probabilities. First, the learning condition induced one set of Start probabilities of trying various rules. Second, should this first hypothesis prove wrong, the learning condition induced a second set of Choice probabilities of considering various rules. These findings broaden our understanding of effective instruction and provide implications for instructional design. (shrink)

How can it be rational to work on a new theory that does not yet meet the standards for good or acceptable theories? If diversity of approaches is a condition for scientific progress, how can a scientific community achieve such progress when each member does what it is rational to do, namely work on the best theory? These two methodological problems, the problem of pursuit and the problem of diversity, can be solved by taking into account the cognitive risk (...) that is involved in theory choice. I compare this solution to other proposals, in particular T. S. Kuhn's and P. Kitcher's view that the two problems demonstrate the epistemic significance of the scientific community. (shrink)

Some philosophers have recently argued that decision-makers ought to take normative uncertainty into account in their decisionmaking. These philosophers argue that, just as it is plausible that we should maximize expected value under empirical uncertainty, it is plausible that we should maximize expected choice-worthiness under normative uncertainty. However, such an approach faces two serious problems: how to deal with merely ordinal theories, which do not give sense to the idea of magnitudes of choice-worthiness; and how, even when (...) theories do give sense to magnitudes of choice-worthiness, to compare magnitudes of choice-worthiness across different theories. Some critics have suggested that these problems are fatal to the project of developing a normative account of decision-making under normative uncertainty. The primary purpose of this article is to show that this is not the case. To this end, I develop an analogy between decision-making under normative uncertainty and the problem of social choice, and then argue that the Borda Rule provides the best way of making decisions in the face of merely ordinal theories and intertheoretic incomparability.

We propose a two-step guessing game to measure the depth of thinking. We apply this method to the P beauty contest game. Using our method, we find that 81% of subjects do not make choice following best response reasoning while the classical method would suggest only 12%. The result suggests that the classical method has the fundamental problem that it cannot distinguish if a submitted number is due to best response reasoning or not. It also suggests that traditional level (...) k analysis falsely attributes some sophistication to random players, and that the degree of false attribution is large. Our procedure provides an alternative way to identify whether the individual has best response reasoning which is essential for any positive level of depth of thinking and differentiates between the depth of thinking and random choice, and hence provides a very different conclusion, which is suggestive of limitations of the classical method.

Early in _Movements of the Mind_, Wayne Wu puts forth a foundational picture of action. On this picture, intentional action is necessarily a solution to a selection problem, a problem of choice among multiple causally possible alternatives. Forming an intention solves one selection problem; acting on that intention requires solving yet further selection problems about how to execute that intention. There are two serious issues with this picture of action. First: some intentional actions are causally necessitated. They can't (...) be solutions to selection problems. Wu's argument for this claim, which contrasts reflex with action, does not succeed in showing that action must solve a selection problem — nor that reflex does not solve such a problem. Second: the requirement to solve further selection problems while acting on an intention leads to a vicious regress that threatens the possibility of action in general. If these two issues are addressed, Wu's groundbreaking scientific approach to mental action might offer us a powerful new theory of ongoing causal control over intentional action. (shrink)

This paper distinguishes an index ordering and a social ordering function as a simple way to formalize the indexing problem in the social choice framework. Two main conclusions are derived. First, the alleged dilemma between welfarism and perfectionism is shown to involve a third possibility, exemplified by the fairness approach to social choice. Second, the idea that an individual is better off than another whenever he has more (goods, functionings, etc.) in all dimensions, which is known to enter (...) in conflict with the Pareto principle, can be partly salvaged by adopting the fairness approach.

In this paper I outline an “agent-centered” approach to learning ethics. The approach is “agent-centered” in that its central aim is to prepare students toact wisely and responsibly when faced with moral problems. The methods characteristic of this approach are suitable for integrating material on professional and research ethics into technical courses, as well as for free-standing ethics courses. The analogy I draw between ethical problems and design problems clarifies the character of ethical problems as they (...) are experienced by those who must respond to them. It exposes the mistake, common in ethics teaching, of misrepresenting moral problems as multiple-choice problems, especially in the form of ‘dilemmas’, that is, a forced choice between two unacceptable alternatives. Furthermore, I clarify the importance for responsible practice of recognizing any ambiguity in the problem situation. (shrink)

Extensive social choice theory is used to study the problem of measuring group fitness in a two-level biological hierarchy. Both fixed and variable group size are considered. Axioms are identified that imply that the group measure satisfies a form of consequentialism in which group fitness only depends on the viabilities and fecundities of the individuals at the lower level in the hierarchy. This kind of consequentialism can take account of the group fitness advantages of germ-soma specialization, which is not (...) possible with an alternative social choice framework proposed by Okasha, but which is an essential feature of the index of group fitness for a multicellular organism introduced by Michod, Viossat, Solari, Hurand, and Nedelcu to analyze the unicellular-multicellular evolutionary transition. The new framework is also used to analyze the fitness decoupling between levels that takes place during an evolutionary transition. (shrink)

According to an often repeated definition, economics is the science of individual choices and their consequences. The emphasis on choice is often used – implicitly or explicitly – to mark a contrast between markets and the state: While the price mechanism in well-functioning markets preserves freedom of choice and still efficiently coordinates individual actions, the state has to rely to some degree on coercion to coordinate individual actions. Since coercion should not be used arbitrarily, coordination by the state (...) needs to be legitimized by the consent of its citizens. The emphasis in economic theory on freedom of choice in the market sphere suggests that legitimization in the market sphere is “automatic” and that markets can thus avoid the typical legitimization problem of the state. In this paper, I shall question the alleged dichotomy between legitimization in the market and in the state. I shall argue that it is the result of a conflation of choice and consent in economics and show how an independent concept of consent makes the need for legitimization of market transactions visible.

Except for some eliminativists, the notion of intentionality is considered to be oneof the common goods of 20th century philosophy of mind. However, this rather general label may hide deeper differences. In his 'Husserl Memorial Lecture' Jocelyn Benoist investigates the different possible conceptions of intentionality and the problem of its nature. To examine this question he concurs with Wilfrid Sellars and John McDowell by positing an alternative between two conceptions of intentionality, taken either as a relation or not. From this (...) point of view he shows how Franz Brentano, who at the threshold of contemporary philosophy regained this notion, maintains a non-relational understanding of intentionality, whereas Husserl and McDowell up to a certain point adopt a relational conception — even though the formalism of relation might in fact not be the most appropriate to render the whole flavor of Husserl's position. The author wants to demonstrate that inside the conception, which rightly or wrongly is called relational, a new choice has to be made, depending on the moment actually assigned to this formalism of 'relations' and to the extent in which the 'relation' is taken for granted. Eventually, he intends to contrast philosophies of two kinds: those which in the last resort rely ona concept of acquaintance, itself undiscussed, and those which convert intentionality into a means for describing the perpetual 'presence' while defining its problem. La notion d'intentionalité semble constituer un bien commun de la philosophie de l'esprit du XXe siècle, à l'exception de certains éliminativistes. Pourtant ce label quelque peu général peut recouvrir des differences assez profondes. Dans sa “Husserl Memorial Lecture”, Jocelyn Benoist revient sur les différentes conceptions possibles de l'intentionalité et le problème de la nature de l'intentionalité. Pour poser cette question, il suit Wilfrid Sellars et John McDowell dans la formulation d'une alternative entre une conception pour laquelle l'intentionalité serait une relation et une autre pour laquelle elle n'en serait pas une. Il montre comment, de ce point de vue, le réinventeur de la notion à l'orée de la philosophie contemporaine, Franz Brentano, soutient en fait une conception non relationnelle de l'intentionalité, et comment au contraire, en un certain sens, Husserl et McDowell adoptent une conception relationnelle (même si le formalisme des relations n'est peut-être pas le meilleur en fait pour exprimer tout le suc de la position de Husserl). Son objectif est de démontrer que, au sein de cette conceptiondite, à tort ou à raison, relationnelle, il y a de nouveau un choix à faire, suivant lavaleur qu'on accorde, précisément, à ce formalisme des ‘relations’, et jusqu'à quel point on tient la ‘relation’ pour acquise ou non. En dernière instance, son propos est d'opposer les philosophies qui, en dernier ressort, s'appuient sur un concept d'acquaintance ininterrogé comme tel, et celles qui font de l'intentionalité un moyen de problématisation et de description de cette ‘présence’ perceptuelle.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Chances and Choices: Exploring the Impact of Music Education by Stephanie PittsLeonard TanStephanie Pitts, Chances and Choices: Exploring the Impact of Music Education (Oxford: Oxford University Press, 2012)In Chances and Choices: Exploring the Impact of Music Education, Stephanie Pitts investigates the lifelong effects of music education by examining the place of music in the lives of more than a hundred adults. Cast in seven chapters, this qualitative study (...) includes six pairs of interludes inserted between the chapters as well as a concluding postlude. Following a brief summary of the book, I will offer my critical response.In Chapter One, Pitts lists the six primary aims of the study: to examine the impact of musical learning during childhood on lifelong engagement with music; to assess the role that school music plays in lifelong involvement in music and attitudes to music; to investigate the influence of various locations for learning; to discuss particular strengths of music education; to probe into the problems of music education systems; and to proffer ways in which knowing more about the long-term implications of music education can help inform practice. She then presents the life history methodology she employs to accomplish these aims, detailing how she gathers retrospective accounts of formative musical experiences by British classical musicians, supplemented by accounts from British popular musicians and Italian respondents. These accounts constitute the data that are [End Page 102] analyzed from different perspectives later in the book. A brief survey of international approaches to music education and outline of the chapters to follow conclude the chapter.In Chapter Two, Pitts sketches a brief overview of twentieth century British music education before analyzing trends in the formative musical experience of British respondents from the 1930s to the 1990s. In an attempt to determine generational trends, Pitts groups the written responses according to six categories of musical influences: classroom music, music outside the classroom, teacher attitudes, music in the home, parent attitudes, and lifelong involvement. For each decade, Pitts presents a rank ordering of the six musical influences, revealing the increasing importance of music outside the classroom through the decades. Pitts then examines the various locations where musical learning takes place, such as the school, the home, and the church, in Chapter Three. Here, she surveys the characteristics of supportive musical environments, examines extracurricular music making, and discusses self-learning in music. Pitts concludes the chapter by analyzing findings from the Italian participants, drawing attention to the fact that in its emphasis on specialist training, the Italian music education system differs from the generalist approaches of its British counterpart.Pithily titled “Inspiring, Affirming, Challenging,” Chapter Four explores the characteristics of memorable and significant music teachers and role models. Among the many themes considered, Pitts notes that inspiring teachers are those who provide constant support to their students and possess advanced musical skills; teachers who were recollected negatively, on the other hand, were associated with being negligent, incompetent, dismissive, or fearsome. In addition, Pitts also explores the role of parents, siblings, extended family, and friends as musical mentors, role models, and sources of musical learning. With these foundations for musical learning established, Pitts analyzes the life history accounts of the respondents by musical outcome in Chapter Five. She discusses how adults make music in community settings, educational settings, worship settings, self-directed groups, and private homes, and describes how adults learn music and attend concerts as a form of lifelong musical involvement. From the data, Pitts surmises that even after leaving school, the participants often desire to improve musically; they frequently concentrate their efforts not only on participating in musical activities, but also on developing their musical skills further.In Chapter Six, “Rhetoric and Reality,” Pitts assesses the degree to which the participants’ experiences corroborate contemporary claims for the value and effects of musical learning. Drawing on the rich data of life history accounts, Pitts concludes that there is “compelling evidence for the lifelong impact of musical education” (p. 173), further arguing that the musical skills, attitudes, and values acquired during school years do have a long-term influence on musical engagement [End Page 103] in later years. Chapter Seven, aptly titled “Chances, Choices, and Conclusion... (shrink)
