An important theme in recent experimental philosophy is that certain judgements (e.g. our judgements involving intentional action and causation) exhibit a kind of normative penetration whereby, in spite of a not-obviously-normative subject matter, they turn out to be sensitive to, and co-vary with, our normative attitudes in interesting and surprising ways. We present the results of several new experimental studies that suggest that our judgements about feasibility also appear to exhibit this kind of normative penetration in at least some (...) cases; that the best explanation of it involves attributing to subjects a certain kind of extensional error that results from conflating the question at hand with another question that is more salient given their normative attitudes; and that these conclusions have significant, though not straightforward, implications for our understanding of both normative penetration and feasibility, respectively.

It is commonly taken for granted that questions of feasibility are highly relevant to our normative thinking – and perhaps especially our normative thinking about politics. But what exactly does this preoccupation with feasibility amount to, and in what forms if any is it warranted? This article aims to provide a critical introduction to, and clearer characterization of, the feasibility issue. I begin by discussing the question of how feasibility is to be understood. I then turn (...) to the question of feasibility’s role, suggesting that there are two quite different kinds of role questions that may be at play, though they are often run together: a question about feasibility’s normative significance; and a question about its proper use in informing our normative thinking. Finally, I consider how the feasibility issue differs from certain other related issues: the demandingness issue; the issue of whether “ought” implies “can;” and the “ideal versus non-ideal theory” issue.

I contend that to be politically feasible a global climate treaty must satisfy the International Paretian principle (IP). I begin by defending IP as a principle of instrumental rationality that reflects the fact of extremely limited altruism vis-à-vis foreigners. I then address two objections to my thesis. One holds that an IP treaty is either economically infeasible or, contrary to its proponents’ claim, does not require side payments from poor states to rich ones. The other holds poor states will reject (...) any climate treaty that requires such side payments because it ignores or exacerbates their unjust treatment by rich states. (shrink)

How feasible are conceptual engineering projects of social concepts that aim for the engineered concept to be widely adopted in ordinary everyday life? Predominant frameworks on the psychology of concepts that shape work on stereotyping, bias, and machine learning have grim implications for the prospects of conceptual engineers: conceptual engineering efforts are ineffective in promoting certain social-conceptual changes. Specifically, since conceptual components that give rise to problematic social stereotypes are sensitive to statistical structures of the environment, purely conceptual change won’t (...) be possible without corresponding world change. This tradition, however, tends to ignore that concepts don’t only encode statistical, but also causal information. Paying attention to this feature of concepts, I argue, shows that conceptual engineering is not only possible. There is an imperative to conceptually-engineer. (shrink)

The object of this paper is to explore the intersection of two issues. The first concerns the role that feasibility considerations play in constraining normative claims – claims, say, about what we (individually and collectively) ought to do and to be. The second concerns whether normative claims are to be understood as applying only to actions in their own right or also non-derivatively to attitudes. In particular, we argue that actions and attitudes may be subject to different feasibility (...) constraints – and hence that how we conceive of the role of feasibility in an account of normativity will depend in part on how we conceive of the role of actions and attitudes in normative theorising. (shrink)

It is natural and relatively common to suppose that feasibility is a constraint on what we ought to do all-things-considered but not a constraint on what we ought to do as a matter of justice. I show that the combination of these claims entails an implausible picture of the relation between feasibility and desirability given an attractive understanding of the relation between what we ought to do as a matter of justice and what we ought to do all-things-considered.

I present and argue for a novel function-based account of feasibility - what I call the "Fitting Deliberation Account" - according to which whether an (individual or collective) action counts as feasible is a matter of whether it possesses those features that are required to make it a fitting object of practical reason or deliberation about what to do.

Some realists in political theory deny that the notion of feasibility has any place in realist theory, while others claim that feasibility constraints are essential elements of realist normative theorising. But none have so far clarified what exactly they are referring to when thinking of feasibility and political realism together. In this article, we develop a conception of the realist feasibility frontier based on an appraisal of how political realism should be distinguished from non-ideal theories. In (...) this realist framework, political standards are feasible if they meet three requirements: they are politically intelligible, contextually recognisable as authoritative, and contestable. We conclude by suggesting that our conception of realist feasibility might be compatible with utopian demands, thereby possibly finding favour with realists who otherwise refuse to resort to the notion of feasibility.

Social interactions and personal relationships are essential for a minimally good life, and rights to such things – social rights – have been increasingly acknowledged in the literature. The question as to what extent social rights are feasible – and properly qualify as rights – however, remains. Can individuals reliably provide each other with love and friendship after trying, for instance? At first glance, this claim seems counterintuitive. This paper argues, contrary to our pre-theoretic intuitions, that individuals can reliably provide (...) each other with such relationships, rendering even “thick” social rights feasible. This conclusion challenges the assumption that such things cannot be reliably provided after trying, and suggests that a surprisingly wide class of social rights are feasible. Claiming relationships characterised by love or friendship as a matter of justice, therefore, is possible, and our theories of justice should appropriately widen to accommodate this fact where appropriate.

Many of us feel internally conflicted in the face of certain normative claims that make infeasible demands: say, normative claims that demand that agents do what, given deeply entrenched objectionable character traits, they cannot bring themselves to do. On the one hand, such claims may seem false on account of demanding the infeasible, and insisting otherwise may seem to amount to objectionable unworldliness – to chasing “pies in the sky.” On the other hand, such claims may seem true in spite (...) of making infeasible demands, and insisting otherwise may seem to amount to treating the agents in question with undue lenience – to mistakenly letting them “off the hook.” What is going on? One possibility is that we are making a mistake. I explore the alternative hypothesis that our ambivalent reactions, far from involving any mistake, are entirely consistent and appropriate. Rather than some single privileged ought such that the idea that “ought” implies “feasible” is either true or false, there are simply different oughts that are supposed to be capable of operating in the service of, and playing distinct roles associated with, what I shall call different core normative practices. In particular, there is a) some salient core practice-serving ought for which it’s true that “ought” implies “feasible” and b) some other salient core practice-serving ought for which it’s false that “ought” implies “feasible.” I sketch a framework for understanding different core practice-serving oughts in general and then use this framework to consider which particular core practice-serving oughts might be capable of vindicating our ambivalence. I begin by considering and rejecting a prevalent and prima facie promising account according to which the relevant oughts are the prescriptive ought and the evaluative ought. I then propose a different account that holds that the oughts we need are instead the deliberative ought and the hypological ought. (shrink)

The familiar complaint that some ambitious proposal is infeasible naturally invites the following response: Once upon a time, the abolition of slavery and the enfranchisement of women seemed infeasible, yet these things were actually achieved. Presumably, then, many of those things that seem infeasible in our own time may well be achieved too and, thus, turn out to have been perfectly feasible after all. The Appeal to History, as we call it, is a bad argument. It is not true that (...) if some desirable state of affairs was actually achieved, then it was feasible that it was achieved. “Actual” does not imply “feasible,” as we put it. Here is our objection. “Feasible” implies “not counterfactually fluky.” But “actual” does not imply “not counterfactually fluky.” So, “actual” does not imply “feasible.” While something like the Flukiness Objection is sometimes hinted at in the context of the related literature on abilities, it has not been developed in any detail, and both premises are inadequately motivated. We offer a novel articulation of the Flukiness Objection that is both more precise and better motivated. Our conclusions have important implications, not only for the admissible use of history in normative argument, but also by potentially circumscribing the normative claims that are applicable to us.

There is a widespread belief that, conceptually, justice cannot require what we cannot achieve. This belief is sometimes used by defenders of so-called ‘non-ideal theories of justice’ to criticise so-called ‘ideal theories of justice’. I refer to this claim as ‘the feasibility constraint on the concept of justice’ and argue against it. I point to its various implausible implications and contend that a willingness to apply the label ‘unjust’ to some regrettable situations that we cannot fix is going to (...) enhance the action-guiding potential of a conception of justice, by providing an aspirational ideal. This is possible on the condition that, at all times, we cannot specify with certainty the limits of what is feasible for us collectively. The rejection of the feasibility constraint entails that there can be injustice without perpetrators; this is a theoretical price worth paying. (shrink)

Climate change goals and actions are often discussed with reference to their feasibility. However, in the climate change literature, there is no agreed upon understanding of what feasibility means. In this paper, insights from political philosophy are used to address this problem in a two-fold way. First, different uses of the term feasibility in the climate change context are critically analyzed, surfacing problematic uses that can have severe consequences for what goals or actions are considered. Second, the (...) ‘conditional probability account of feasibility’ is presented as a positive account of how feasibility should be understood in the climate change context, and applied to the case of managed retreat as an approach for adaptation to sea level rise. Together, the critical analysis and the positive proposal furthers a necessary discussion on feasibility in the context of climate change. (shrink)

Recent methodological debates regarding the place of feasibility considerations in normative political theory are hindered for want of a rigorous model of the feasibility frontier. To address this shortfall, I present an analysis of feasibility that generalizes the economic concept of a production possibility frontier and then develop a rigorous model of the feasibility frontier using the familiar possible worlds technology. I then show that this model has significant methodological implications for political philosophy. On the Target (...) View, a political ideal presents a long-term goal for morally progressive reform efforts and, thus, serves as an important reference point for our specification of normative political principles. I use the model to show that we can- not reasonably expect that adopting political ideals as long-term reform objectives will guide us toward the realization of morally optimal feasible states of affairs. I conclude by proposing that political philosophers turn their attention to the analysis of actual social failures rather than political ideals. (shrink)

Several authors have pointed at opportunities to develop the well-established Business Balanced Scorecard into a Scorecard that enables companies to integrate sustainability into their strategy. Recent case studies and research experiences show that social and environmental targets are more widely recognized as strategic drivers for management. However, experiments also show that the traditional Scorecard has its limits when it comes to e.g. stakeholder management and product chain management. The European Corporate Sustainability Framework(ECSF) program distinguishes several ambition levels for Corporate Sustainability/corporate (...) Responsibility. The traditional Balanced Scorecard is suitable for companies that aim for Compliance-driven CS/cror for Profit-driven CS/cr, where the financial bottom line is the ultimate indicator for success. More ambitious companies want to balance economic, social and ecological targets in a Community-driven CS/sror Synergy-driven CS/cr.For ambitious companies, we propose a format of a Responsive Business Scorecard (RBS). The Responsive Scorecard enables companies to score at Profit, People and Planet, at the same time to integrate stakeholder demands into internal programs to improve performance. The RBS includes five Perspectives: Customers&Suppliers, Financiers&Owners, Society&Planet, Internal Process and Employees&Learning.We assessed the practical feasibility of a Responsive Scorecardin food and tourist industries. In the food industry, we analyzed whether existing business priorities of Italian companies can adequately fill a Responsive scorecard.Our conclusion is that traditional topics like finance, customers and employees are readily filled, but that sustainability topics like chain management (suppliers) and environmental performance (planet) need further elaboration. The tourist sector is dominated by Small and Medium Sized Enterprises. We investigated whether existing eco-labels for camping-sites and marinas can be developed into Responsive Scorecards. Our conclusion is that such a sector specific development of a Responsive Scorecard is possible. Further research has to show what is the value added of the new scorecard for companies in the tourist sector. (shrink)

The concept of feasibility has received a significant amount of scrutiny in recent years. Despite the diversity of accounts, all agree on the assumption that feasibility considerations have a practical function in guiding action. However, the two most important accounts (by Gilabert and Lawford-Smith, and by Wiens) seem to scarcely speak to this practical function because they provide a third-personal reconstruction of feasibility constraints. In this paper, I argue that, to understand feasibility constraints in a way (...) that matters for guiding action, we should switch from a third-personal to an agent-centered perspective. I show that relevant constraints can be Barriers, Limitations, Boundaries, and Rubber Walls to the extent that they concern nomic impossibilities (Barriers), resources (Limitations), agents’ abilities (Boundaries) or other people’s unwillingness (Rubber Walls). Understanding constraints through the lens of their qualitatively different natures opens the way for addressing the problem of how to respond to them. (shrink)

Abstract:Both the idea of feasibility and the role that it might play within political theory are controversial. Recent discussions have attempted to specify an appropriate overall conceptualization of feasibility. This essay offers a more nuanced account of a number of interrelated aspects of feasibility and argues for a more realistic view of feasibility. Four aspects of feasibility are identified and discussed: resource feasibility, value feasibility, human feasibility, and institutional feasibility.

To be justifiable, the demands of a conception of human rights and global justice must be such that (a) they focus on the protection of important human interests, and (b) their fulfilment is feasible. I discuss the feasibility condition. I present a general account of the relation between moral desirability, feasibility and obligation within a conception of justice. I analyse feasibility, a complex idea including different types, domains and degrees. It is possible to respond in various ways (...) if the fulfilment of basic socioeconomic human rights against severe poverty seems at first to be infeasible. (shrink)

The feasibility constraint on the concept of justice roughly states that a necessary condition for something to qualify as a conception of justice is that it is possible to achieve and maintain given the conditions of the human world. In this paper, I propose three alternative interpretations of this constraint that could be derived from different understandings of the Kantian formula ‘ought implies can’: the ability constraint, the motivational constraint and the institutional constraint. I argue that the three constraints (...) constitute a sequence in the sense that accepting the motivational constraint presupposes that we accept the ability constraint, and to accept the institutional constraint presupposes that we accept both previous constraints. Adding the possibility of rejecting all three constraints, we get four distinct metatheoretical positions that theorists could take vis-à-vis the feasibility constraint on justice. (shrink)

The on-going space settlement debate has raised questions whether it is possible to settle other planets, and if it was, is it something humans should do. The problem with this space ethical discussion is that it can easily become too vague. To avoid this problem, we suggest a framework for identifying relevant variables that affect the feasibility constraints and desirability factors of establishing space settlements. The variables we focus on include the settlement stage, scale and time frame. Based on (...) the relevant literature, we take mission cost, survival, habitation, water, in situ resources for food, oxygen and fuel energy and dependence on Earth as feasibility constraints that are relevant for the framework. None of them are hard constraints, but rather soft feasibility constraints that make it difficult to establish a permanent human settlement on Mars in the near- to medium-term future. However, in the past, humanity has achieved goals that first seemed infeasible. To justify the costs and effort, the goal must be highly morally desirable. We discuss five different desirability factors that could help justify the effort but as each framework has unique feasibility constraints, not all of these factors are sufficient or necessary to justify this effort. We argue that some of the desirability factors prominent in space ethical literature are not sufficient or necessary in our framework, and thus, we conclude that the normative grounds for establishing a permanent Mars settlement in the foreseeable future are weak.

: Accusations of infeasibility or utopianism are common in debates over libertarian institutions, but exactly what we mean when we say an idea is “utopian” or “infeasible” is often left unspecified.

If folk science means individuals having well worked out mechanistic theories of the workings of the world, then it is not feasible. Laypeople’s explanatory understandings are remarkably coarse, full of gaps, and often full of inconsistencies. Even worse, most people overestimate their own understandings. Yet recent views suggest that formal scientists may not be so different. In spite of these limitations, science somehow works and its success offers hope for the feasibility of folk science as well. The success of (...) science arises from the ways in which scientists learn to leverage understandings in other minds and to outsource explanatory work through sophisticated methods of deference and simplification of complex systems. Three studies ask whether analogous processes might be present not only in laypeople but also in young children and thereby form a foundation for supplementing explanatory understandings almost from the start of our first attempts to make sense of the world.

Many assert that affluent countries have contributed in the past to poverty in developing countries through wars of aggression and conquest, colonialism and its legacies, the imposition of puppet leaders, and support for brutal dictators and venal elites. Thomas Pogge has recently argued that there is an additional and, arguably, even more consequential way in which the affluent continue to contribute to poverty in the developing world. He argues that when people cooperate in instituting and upholding institutional arrangements that foreseeably (...) result in more severe or more widespread poverty or human rights deficits than would foreseeably result under feasible alternative arrangements, they are contributors to these harms. Because of this, he argues, they have stringent, contribution-based (or negative) duties to address this poverty. We will call this the ‘Feasible Alternatives Thesis' (FAT), and our aim in this article is to examine it critically. (shrink)

Does ?ought? imply ?can? for collectives' obligations? In this paper I want to establish two things. The first, what a collective obligation means for members of the collective. The second, how collective ability can be ascertained. I argue that there are four general kinds of obligation, which devolve from collectives to members in different ways, and I give an account of the distribution of obligation from collectives to members for each of these kinds. One implication of understanding collective obligation and (...) ability in the proposed way is that a group can be blameworthy for failing to realize its obligation even when no member of the group is blameworthy for failing to realize her obligation.

It is common in political theory and practice to challenge normatively ambitious proposals by saying that their fulfillment is not feasible. But there has been insufficient conceptual exploration of what feasibility is, and very little substantive inquiry into why and how it matters for thinking about social justice.

It is a crucial question whether practicalities should have an impact in developing an applicable theory of human rights—and if, how (far) such constraints can be justified. In the course of the non-ideal turn of today’s political philosophy, any entitlements (and social entitlements in particular) stand under the proviso of practical feasibility. It would, after all, be unreasonable to demand something which is, under the given political and economic circumstances, unachievable. Thus, many theorist—particularly those belonging to the liberal camp—begin (...) to question the very idea of social human rights on grounds of practical infeasibility. This new minimalism about human rights motivates an immanent critique arguing that even if we were to proceed from a liberal framework, we would still wind up with a justification of the full list of social human rights. In the first part of this article, I will present the central positions of the debate presented by Amartya Sen, Maurice Cranston and Pablo Gilabert. Initially arguing that a minimalism of human rights on grounds of practical infeasibility alone proves unjustifiable, however, I shall open up two further perspectives, which allow practical infeasibilities to become normatively determinate. Discussing contributions by James Griffin and Charles Beitz, I will defend the thesis that certain feasibility constraints on (social) human rights can be justified on the condition that they are grounded either in a normative idea of the appropriate implementation of these rights or in reflection of the practical function of a theory of human rights.

Political philosophy offers a range of utopian proposals, from open borders to global egalitarianism. Some object that these proposals ought to be constrained by what is feasible, while others insist that what justice demands does not depend on what we can bring about. Currently, this debate is mired in disputes over the fundamental nature of justice and the ultimate purpose of political philosophy. I take a different approach, proposing that we should consider which facts could fill out a feasibility (...) requirement. This search for the facts requires requires looking to the social sciences, but I argue that it turns out that the social sciences will not provide us with findings that rule out, nor even count against, the kinds of proposals that political philosophers actually make, whether ideal or non-ideal. At the least, to deny this requires adopting deeply controversial commitments within the philosophy of social science. Thus, I conclude that a feasibility requirement has little practical use for political philosophers. Disputes over that requirement ought to be replaced by other, more fruitful ways for political philosophers to address both the findings of social science and the debates over non-ideal theory or political realism.

Recent years have seen an explosion of empirical data concerning arithmetical cognition. In this paper that data is taken to be philosophically important and an outline for an empirically feasible epistemological theory of arithmetic is presented. The epistemological theory is based on the empirically well-supported hypothesis that our arithmetical ability is built on a protoarithmetical ability to categorize observations in terms of quantities that we have already as infants and share with many nonhuman animals. It is argued here that arithmetical (...) knowledge developed in such a way cannot be totally conceptual in the sense relevant to the philosophy of arithmetic, but neither can arithmetic understood to be empirical. Rather, we need to develop a contextual a priori notion of arithmetical knowledge that preserves the special mathematical characteristics without ignoring the roots of arithmetical cognition. Such a contextual a priori theory is shown not to require any ontologically problematic assumptions, in addition to fitting well within a standard framework of general epistemology. (shrink)

BackgroundDepression and anxiety create a large health burden and increase the risk of premature mortality. Mental health screening is vital, but more sophisticated screening and monitoring methods are needed.

Additionally, we aim to demonstrate portability and improved performance of Ellipsis’ machine (...) learning models for patients of various ages.MethodsStudy participants were current patients at Desert Oasis Healthcare, mean age 63 years. Two non-randomized cohorts participated: one with a documented history of depression within 24 months prior to the study, and the other without depression. Participants recorded 5-min voice samples weekly for 6 weeks via the Ellipsis Health App. They also completed PHQ-8 and GAD-7 questionnaires to assess for depression and anxiety, respectively.ResultsProtocol completion rate was 61% for both groups. Use beyond protocol was 27% for Group Positive and 9% for Group Negative. The Ellipsis Health App showed an AUC of 0.82 for the combined groups when compared to the PHQ-8 and GAD-7 with a threshold score of 10. Performance was high for senior participants as well as younger age ranges. Additionally, many participants spoke longer than the required 5 min.ConclusionThe Ellipsis Health App demonstrated feasibility in using voice recordings to screen for depression and anxiety among various age groups and the machine learning models using Transformer methodology maintain performance and improve over LSTM methodology when applied to the study population.

An important question in language evolution is whether segmentation as a linguistic process is able to yield compositionality. Segmentation is hypothesized to be a process to bridge the gap between holistic and compositional lexicons. However, to date no thorough analytical method has been provided to test the feasibility of segmentation. In this paper, an analytical model is presented that can predict the probability of encountering various kinds of overlaps by observing utterance pairs, and the probability of finding confirmation in (...) the language for newly extracted segments. Language users start by using a previously evolved holistic lexicon to communicate about simple environments. They segment these holistic utterances to smaller pieces, which can be used as elements of a compositional lexicon. The model reveals that the feasibility of segmentation depends on the definition of counterexamples, i.e. those associations (pairs), which either cause ambiguous extraction of segments, or do not allow segmentation at all. On one hand if inexact overlaps are considered to be contradictory (i.e. causing confusion) to a perfect exact overlap, then the probability is so minuscule that it renders the role of segmentation marginal during language evolution. On the other hand, if such inexact counterexamples are able to be segmented unambiguously due to extra cognitive capacities, segmentation may have a much higher feasibility.

Many political philosophers hold the Feasible Alternatives Principle (FAP): justice demands that we implement some reform of international institutions P only if P is feasible and P improves upon the status quo from the standpoint of justice. The FAP implies that any argument for a moral requirement to implement P must incorporate claims whose content pertains to the causal processes that explain the current state of affairs. Yet, philosophers routinely neglect the need to attend to actual causal processes. This undermines (...) their arguments concerning moral requirements to reform international institutions. The upshot is that philosophers’ arguments must engage in causal analysis to a greater extent than is typical. -/- [Supplement: Handout available at http://db.tt/fyuVW3Xv]. (shrink)

Arguments from stability for liberal nationalism rely on considerations about conditions for the feasibility or stability of liberal political ideals and factual claims about the circumstances under which these conditions are fulfilled in order to argue for nationalist conclusions. Such reliance on factual claims has been criticised by among others G. A. Cohen in other contexts as ideological reifications of social reality. In order to assess whether arguments from stability within liberal nationalism, especially as formulated by David Miller, are (...) vulnerable to a comparable critique, the rationale for their reliance on factual claims is discussed on the basis of a number of concerns in John Rawls’s political liberalism. The concern with stability in liberal nationalism differs from stability in Rawls’s work, mainly because of the stronger non-ideal or ‘realist’ focus of the former. In so far as the ‘realism’ of arguments from stability for liberal nationalism is recognized, they are not vulnerable to the reification charge. But if the arguments are construed as realist, this at the same time makes for other tensions within liberal nationalism. (shrink)

The problem of when a recursive graph has a recursive k-coloring has been extensively studied by Bean, Schmerl, Kierstead, Remmel, and others. In this paper, we study the polynomial time analogue of that problem. We develop a number of negative and positive results about colorings of polynomial time graphs. For example, we show that for any recursive graph G and for any k, there is a polynomial time graph G′ whose vertex set is {0,1}* such that there is an effective (...) degree preserving correspondence between the set of k-colorings of G and the set of k-colorings of G′ and hence there are many examples of k-colorable polynomial time graphs with no recursive k-colorings. Moreover, even though every connected 2-colorable recursive graph is recursively 2-colorable, there are connected 2-colorable polynomial time graphs which have no primitive recursive 2-coloring. We also give some sufficient conditions which will guarantee that a polynomial time graph has a polynomial time or exponential time coloring. (shrink)

It is commonly stated, by both whistleblower protection laws and political philosophers, that a breach of state secrecy by disclosing classified documents is justified if it serves the public interest. The problem with this defense of justified whistleblowing, however, is that the operative term – the public interest – is all too often left unclarified. This is problematic, because it leaves potential whistleblowers without sufficient certainty that their disclosures will be covered by the defense, leading many to err on the (...) side of caution and remain silent, depriving the public of much-needed information. Failing an agreed upon definition of the public interest or a process to determine it, judges’ applications of the public interest in whistleblowing cases have been criticized for demonstrating ‘judicial idiosyncrasy’.

While methodological and metatheoretical questions pertaining to feasibility have been intensively discussed in the philosophical literature on feasibility and justice in recent years, these discussions have not permeated the debate on global democracy. The overall aim in this paper is to demonstrate the fruitfulness of importing some of the advancements made in this literature into the debate on global democracy as well as to develop aspects that are relevant for explaining the role of feasibility in normative political (...) theory. This is done by pursuing two arguments. First, to advance the work on the role of feasibility, we suggest two metatheoretical constraints on normative political theorizing as intuitively plausible – the ‘fitness constraint’ and the ‘functional constraint’ – which elucidate a number of aspects relevant for determining proper feasibility constraints of an account in political theory. Second, to illustrate the usefulness of this feasibility framework, we sketch an account of global democracy consisting of normative principles which respond differently to these aspects and thus are tied to different feasibility constraints as well as exemplify how it may be applied in practice.

We investigated the feasibility of a short intervention using the Method of Loci, a well-known visuospatial mnemonic, to improve episodic memory recall performance in schizophrenia. The MoL training protocol comprised encoding and recall of two lists of items, a training session and practice with MoL. Then, participants had the opportunity to put into practice the newly learned MoL and were instructed to encode and recall two new lists of items using. This approach was first validated with healthy individuals. Subsequently, (...) five individuals with schizophrenia completed the protocol. Improvement in healthy individuals was observed for the word list. No significant memory improvement was denoted in the schizophrenia group, possibly due to participants' difficulties using the method efficiently and due to fatigue. The MoL seems to require episodic memory, working memory monitoring and executive functions, making it suboptimal for a population with impairments in all those domains. Future research should examine the use of other strategies, better suited for individuals with cognitive impairments like those found in schizophrenia. (shrink)

A philosophically important but largely overlooked cognitive theory is examined, one that provides information on which inferences an agent will make from his beliefs. Such a theory of feasible inferences is indispensable in a complete cognitive psychology, in particular, for predicting the agent's actions on the basis of rationality conditions and attributed beliefs and desires. However, very little of the feasibility theory which applies to a typical human being can be shown a priori to apply to all agents. The (...) logical competence required of a rational agent seems to have a cluster structure: it cannot be the case that an agent is able to make no inferences, but an agent can be unable to make any particular one.

The feasible interpolation theorem for semantic derivations from [J. Krajíček, Interpolation theorems, lower bounds for proof systems, and independence results for bounded arithmetic, J. Symbolic Logic 62 457–486] allows to derive from some short semantic derivations of the disjointness of two [Formula: see text] sets [Formula: see text] and [Formula: see text] a small communication protocol computing the Karchmer–Wigderson multi-function [Formula: see text] associated with the sets, and such a protocol further yields a small circuit separating [Formula: see text] from (...) [Formula: see text]. When [Formula: see text] is closed upwards, the protocol computes the monotone Karchmer–Wigderson multi-function [Formula: see text] and the resulting circuit is monotone. Krajíček [Interpolation by a game, Math. Logic Quart. 44 450–458] extended the feasible interpolation theorem to a larger class of semantic derivations using the notion of a real communication complexity. In this paper, we generalize the method to a still larger class of semantic derivations by allowing randomized protocols. We also introduce an extension of the monotone circuit model, monotone circuits with a local oracle, that does correspond to communication protocols for [Formula: see text] making errors. The new randomized feasible interpolation thus shows that a short semantic derivation of the disjointness of [Formula: see text], [Formula: see text] closed upwards, yields a small randomized protocol for [Formula: see text] and hence a small monotone CLO separating the two sets. This research is motivated by the open problem to establish a lower bound for proof system [Formula: see text] operating with clauses formed by linear Boolean functions over [Formula: see text]. The new randomized feasible interpolation applies to this proof system and also to cutting planes CP, to small width resolution over CP of Krajíček [Discretely ordered modules as a first-order extension of the cutting planes proof system, J. Symbolic Logic 63 1582–1596] ) and to random resolution RR of Buss, Kolodziejczyk and Thapen [Fragments of approximate counting, J. Symbolic Logic 79 496–525]. The method does not yield yet lengths-of-proofs lower bounds; for this it is necessary to establish lower bounds for randomized protocols or for monotone CLOs. (shrink)

The EBM+ programme is an attempt to improve the way in which present-day evidence-based medicine (EBM) assesses causal claims: according to EBM+, mechanistic studies should be scrutinised alongside association studies. This paper addresses two worries about EBM+: (i) that it is not feasible in practice, and (ii) that it is too malleable, i.e., its results depend on subjective choices that need to be made in order to implement the procedure. Several responses to these two worries are considered and evaluated. The (...) paper also discusses the question of whether we should have confidence in medical interventions, in the light of Stegenga's arguments for medical nihilism. (shrink)
