It is common practice in intergenerational justice to set fixed thresholds determining what qualifies as justice. Static definitions of how much and what to save for future generations, however, overestimate human epistemological limits and predictive capacity in regard to uncertainty in social- and ecosystems. Long-term predictions cannot account for the inherent range of contingent variables at play, especially according to contemporary theories of punctuated equilibrium. It is argued that policies deliberately testing ecological limits as currently conceived must be excluded from (...) political calculations to minimize current actions from foreclosing future life quality and options. To better reduce harms to present and future generations and support the stability of just institutions (and the stable environments they depend on) as Rawls and others demand, polities can overcompensate resource allocation to environmental sustainability. Focus on reducing environmental harms benefits both current and future generations, reconciling distributive versus intergenerational justice trade-offs. (shrink)

The threshold problem is the task of adequately answering the question: “Where does the threshold lie between knowledge and lack thereof?” I start this paper by articulating two conditions for solving it. The first is that the threshold be neither too high nor too low; the second is that the threshold accommodate the significance of knowledge. In addition to explaining these conditions, I also argue that it is plausible that they can be met. Next, I (...) argue that many popular accounts of knowledge cannot meet them. In particular, I lay out a number of problems that standard accounts of knowledge face in trying to meet these conditions. Finally, near the end of this paper, I argue that there is one sort of account that seems to evade these problems. This sort of account, which is called a cluster account of knowledge, says that knowledge is to be accounted for in terms of truth, belief and a cluster of epistemic properties and also that knowledge doesn’t require having all members of the cluster, but merely some subset.

I consider but reject one broad strategy for answering the threshold problem for fallibilist accounts of knowledge, namely what fixes the degree of probability required for one to know? According to the impurist strategy to be considered, the required degree of probability is fixed by one's practical reasoning situation. I distinguish two different ways to implement the suggested impurist strategy. According to the Relevance Approach, the threshold for a subject to know a proposition at a time is (...) determined by the practical reasoning situations she is then in to which that particular proposition is relevant. According to the Unity Approach, the threshold for a subject to know any proposition whatsoever at a time is determined by a privileged practical reasoning situation she then faces, most plausibly the highest stakes practical reasoning situation she is then in. I argue that neither way of implementing the impurist strategy succeeds and so impurism does not offer a satisfactory response to the threshold problem. (shrink)

The threshold problem for knowledge is the problem of saying where the threshold for knowledge lies in various cases and explaining why it lies there rather than elsewhere. Pragmatic encroachment is the idea that the knowledge-threshold is sensitive to practical factors. The latter idea seems to help us make progress on the former problem. However, Jessica Brown has argued that appearances are deceiving in this case: the threshold problem is still a thorny (...) one even for those who accept pragmatic encroachment. This paper takes a look at Brown’s arguments and at Michael Hannon’s recent attempt to respond to them. Hannon’s response is shown to face serious difficulties and a novel alternative response to Brown is provided. The paper also takes up an issue Brown raises very briefly concerning cases in which a proposition is relevant to multiple stakes which a subject faces at a given time. It turns out that there is a good deal more to be said about how defenders of pragmatic encroachment should try to handle such cases than Brown permits. (shrink)

Climate models calibrated exclusively with observations from the 19th through 21st centuries are unsuitable for assessing many important hypotheses about the future. Many systems in the modern climate are expected to cross dynamic thresholds in the near future, requiring more than the instrumental record for adequate calibration. In this paper I argue that paleoclimate analogues from earth’s past can mitigate this threshold problem, even if the modern climate exhibits features that make it historically unique. While this requires that (...) paleoclimatologists be increasingly discriminate in the past systems they target for modern analogues, the upshot is a practice of climate model construction that improves the reliability of future projections. All of this is achieved by integrating features of past climate systems discovered by the study of earth deep in the past. My analysis synthesizes important empirical work done by climate modelers and paleoclimatologists with relevant philosophical work on analogical reasoning in science. (shrink)

In this paper I articulate and defend a new anti-theodicy challenge to Skeptical Theism. More specifically, I defend the Threshold Problem according to which there is a threshold to the kinds of evils that are in principle justifiable for God to permit, and certain instances of evil are beyond that threshold. I further argue that Skeptical Theism does not have the resources to adequately rebut the Threshold Problem. I argue for this claim by drawing (...) a distinction between a weak and strong version of Skeptical Theism, such that the strong version must be defended in order to rebut the Threshold Problem. However, the skeptical theist’s appeal to our limited cognitive faculties only supports the weak version. (shrink)

Any theory of health justice requires an account of what areas of social life are important enough to be of public concern. What are the goods that ought to be provided as a matter of justice? This is what I will call the metric problem. The capabilities approach puts forward a particular solution to this problem. In this article I will discuss some issues of such an approach in relation to Sridhar Venkatapuram's well-known theory. Another problem I (...) examine is how to determine a threshold of provision within a theory of justice. What is enough in terms of health justice? I argue that we need such a threshold to avoid healthism, the expansion of the pursuit of health over and above the treatment and prevention of disease. This is an especially pertinent problem in public health, which is also the context of Venkatapuram's theory. (shrink)

The paper introduces a new problem for fallibilist and infallibilist epistemologies – the diachronic threshold problem. As the name suggests, this is a problem similar to the well–known threshold problem for fallibilism. The new problem affects both fallibilism and infallibilism, however. The paper argues that anyone who worries about the well known problem for fallibilism should also worry about this new, diachronic version of the problem.

This paper is about the ‘threshold problem’ for knowledge, namely, how do we determine what fixes the level of justification required for knowledge in a non-arbitrary way? One popular strategy for solving this problem is impurism, which is the view that the required level of justification is partly fixed by one’s practical reasoning situation. However, this strategy has been the target of several recent objections. My goal is to propose a new version of impurism that solves the (...) threshold problem without succumbing to these criticisms. (shrink)

One of the primary views on our supposed obligation towards our descendants in the context of environmental problems invokes the idea of the rights of future generations. A growing number of authors also hold that the descendants of those victimized by historical injustices, including colonialism and slavery, have the right to demand financial reparations for the sufferings of their distant ancestors. However, these claims of intergenerational rights face theoretical difficulties, notably the non-identity problem. To circumvent this problem in (...) a relationship between present and future generations, some rights theorists replace future individual rights with such collective rights. Others advance the threshold conception of harm in discussing intergenerational relationships in general. Despite the significant implications these revisionist views might have, few efforts have been made to scrutinize their solidity. To plug such a gap in the literature, this paper examines to what extent the collective understanding of intergenerational rights is pertinent. I also explore the virtues and drawbacks of the threshold interpretation of harm. The paper concludes by suggesting that the motivation behind these and other versions of the rights theory suffers from the ambiguity of a traditional dichotomy between perfect and imperfect duties.

This essay is a historical–geographical account of how scientists and public health officials conceptualized and assessed northern radioactive exposures in the late 1950s and 1960s. The detection of radionuclides in caribou bodies in northern Canada both demonstrated the global reach of nuclear fallout and revealed the unevenness of toxic relations and radioactive exposures. Following the documentation of the lichen–caribou–human pathway of exposure, Canadian public health officials became increasingly concerned about the possibility of heightened radioactive exposures among Indigenous northerners. Between 1963 (...) and 1969, scientists and officials with Canada’s Radiation Protection Division coordinated an interdepartmental monitoring program through which they sought to determine whether the consumption of contaminated caribou meat had caused radioactive exposure levels in northern communities to exceed the officially recognized “safe limits.” In 1969, the northern monitoring program was suspended after officials determined that radionuclide body burdens had not exceeded the threshold for radioactive exposures. While the RPD emphasized its development of a technoscientific approach to measuring radioactive body burdens, the legitimacy of the monitoring program was linked directly to interdepartmental relations within Canada’s colonial northern administration. I situate the northern monitoring program within broader shifts in public health approaches to radiation protection and use Gabrielle Hecht’s concept of nuclearity to demonstrate how RPD officials employed the logic of the threshold in their assessment of radioactive exposures.

The purpose of this paper is to direct attention to a challenge—referred to as the threshold challenge —facing a non-absolutist retributivist view on international criminal justice. It is argued, on the one hand, that this challenge constitutes a practically pertinent problem for the retributivist approach to the punishment of mass crimes and, on the other, that it is very hard to imagine any principled way of meeting this challenge.

On the surface, it seems plausible that the goodness or badness of an agent’s actions should be completely irrelevant to the question of whether she performed them intentionally, but there is growing evidence that ascriptions of intentional actions are affected by moral considerations. Joshua Knobe, for instance, has recently published a series of groundbreaking papers (2003a, 2003b, 2004) in which he suggests that people’s judgments concerning the intentionality of an action may sometimes depend on what they think about the action (...) – morally speaking. One of the more interesting results of Knobe’s psychological experiments is the discovery that people may have a lower threshold for judging that lucky (or unskilled) actions are intentional when these actions are praiseworthy or blameworthy than they do for judging that equally lucky (or unskilled) morally neutral actions are intentional. In this paper I show that this discovery – when supplemented with some additional empirical data – gives us a way of shedding new light on a controversy that was sparked by Ronald Butler in 1977 when he posed the following problem to the readers of Analysis.

Feminists have argued that oppressive socialization undermines the liberal model of autonomy. We contend that this argument can also be employed effectively as a challenge to the standard bioethical model of informed consent. We claim that the standard model is inadequate because it relies on presumptions of procedural autonomy and rational choice that overlook the problem of how agents are often socialized so that they adopt and internalize oppressive norms as part of their motivational structure. The argument that oppressive (...) socialization undermines liberalism’s view of autonomy is most relevant to what Beauchamp and Childress call the threshold elements of informed consent—competence and voluntariness. We show how these elements fail to account for morally relevant factors such as oppressive socialization. (shrink)

A new realislic local model of light propagation and detection is described. The authors propose a novel stochastic model of low-intensity photon detection in which background noise is added to a part of the photon prior to absorption. In this model, in agreement with Planck, there is no quantization of the propagating field. The model has some similarities to theories advanced by E. Santos and T. Marshall in the last decade, but also has substantial deviations from these. A mechanism, conserving (...) energy and momentum, is proposed by which a sudden collapse of the wave-packet is avoided. The experimental Bell inequality violation of Aspect. Grangier and Roger [Phys. Rev. Lett.47, 460 (1981)]is discussed. The authors have carried out a computer simulation of a radio frequency (RF) analogue of the Einstein-Podolsky-Rosen thought experiment to illustrate how the manipulation of certain factors, especially signal to noise ratio, detector threshold and characteristics of the noise, enables the same Bell inequality to be either satisfied or violated by a realistic local model. Building on arguments by Santos. [Phys. Rev. A46. 3646 (1992)],the appropriateness of this Bell lest is discussed. Neither the authors' stochastic-optical model, nor their RF analogue, involves an enhancement assumption of the type defined by Clauser and Horne [Phys. Rev. D10, 526 (1974)]. (shrink)

As a moral foundation for vegetarianism and other consumer choices, act consequentialism can be appealing. When we justify our consumer and dietary choices this way, however, we face the problem that our individual actions rarely actually precipitate more just agricultural and economic practices. This threshold or individual impotence problem engaged by consequentialist vegetarians and their critics extends to morally motivated consumer decision-making more generally, anywhere a lag persists between individual moral actions taken and systemic moral progress made. (...) Regan and others press just this point against Singer's utilitarian basis for vegetarianism; recently Chartier criticizes act-consequentialist vegetarianism by identifying many factors weakening the connection between individual meat purchases and changes in animal production. While such factors are relevant to act-consequentialist moral reasoning, I argue, they need not defeat the act-consequentialist case for vegetarianism and consumer ethics. This is shown by offering a probabilistic account of the threshold issue and discussing the positive and negative role-modelling effects of our morally motivated dietary and consumer choices.

In the long aftermath of such modernist suspicions about the still dominant "official" Enlightenment culture, the very title of the recently translated book by Hans Blumenberg is a bluntly direct invitation to controversy--The Legitimacy of the Modern Age. For Blumenberg, when Giordano Bruno, condemned to burn at the stake in 1600, defiantly turned his face from a crucifix offered him as a last chance at redemption, the heroic gesture should be seen as just that, heroic and historically decisive, a rejection (...) of the reality of the Incarnation, and the expression of a decisively new form of thought. "The Nolan" did cross a real threshold that separates modernity from pre-modernity. The new, for Blumenberg is new, not belated, and what's more heretical still in our post-Nietzschean, post-Heideggerean world, better than the old. The "self-assertion" of modernity is, in a simple word, "legitimate.". (shrink)

This article analyzes the evolution of Philosophy of Educationin Spain and its situation at the dawn of the 21st century. Spain'speculiar socio-historical circumstances have largely conditioned thedirection this discipline has taken over the last several decades. So,although during a period there was some approximation towards themethods of analytic philosophy, Philosophy of Education has never fullyrelinquished its normative vocation. To do so would have meant spurningthe hopes and fears that had filled Spanish society by the mid 1970supon the reinstatement of civil (...) liberties and democracy. Indeed,attention to the circumstances and that normative orientation have foundtheir best fit in a practical Aristotelian-based philosophy meant toendow Philosophy of Education with a normative character that do notshun the educator's need for reflection, practical decision-making, andresponsibility. Since the 1990s, new directions have been marked by thechallenge of postmodernism, inasmuch as it affects not only thetechnological positivist model but also the reflective educator's modelof a practical Philosophy of Education. The new directions spread out invarious ways, yet they all fall into a common denominator of narrativetrends. The problem posed by these new languages lies in the extent towhich they are consistent with pedagogic intent. In turn, the answerstake on different profiles depending on whether the stance leans moretowards the philosophical or the pedagogical point of view withinPhilosophy of Education. The complementary nature of both perspectivescharacterizes the current state of the field in Spain. (shrink)

This paper argues that humans possess unique cognitive abilities due to the presence of a functional system that exists in the human brain that is absent in the non-human brain. This system, the frontal feedback system, was born in the hominin brain when the great phylogenetic expansion of the prefrontal cortex relative to posterior sensory regions surpassed a critical threshold. Surpassing that threshold effectively reversed the preferred direction of information flow in the highest association regions of the neocortex, (...) producing the frontal feedback system. This reversal was from the caudo-rostral bias characteristic of non-human, or pre-human, brain dynamics to a rostro-caudal bias characteristic of modern human brain dynamics. The frontal feedback system works through frontal motor routines, or action schemes, manipulating the release and reconstruction of stored sensory memories in posterior sensory areas. As an obligatory feature of frontal feedback, a central character, or self, emerges within this cortical network that manifests itself as agent in these reconstructions as well as in the experience of sensory perceptions. Dynamical-systems modeling of cortical interactions is combined in the paper with recent neuroimaging studies of “resting-state” brain activity to bridge the gap between microscopic and macroscopic levels of cortical behavior. This synthesis is used to support the proposal of an information flow reversal occurring in the hominin brain and also to explain how such a reversal generates the wide variety of cognitive and experiential phenomena that many consider to be uniquely human.

To provide a theoretical basis for the common view that moral status comes in degrees, many philosophers endorse ‘two-factor’ accounts of the foundations of moral status. These accounts postulate one or more properties which endow individuals with moral status, and one or more other properties which increase the moral status of those who possess them. Critical assessment of two-factor accounts has focused on their implications, especially for humans who lack the properties thought to increase individuals’ moral status. Unfortunately, this approach (...) has led to an impasse. To try to break it, the present manuscript instead assesses the assumption on which two-factor accounts are based, namely, possession of one or more properties, what I call ‘moral status enhancing’ properties, increases their possessors’ moral status. I argue that two challenges, the problem of relevance and the need for a threshold, reveal that there are no moral status enhancing properties, hence, no degrees of moral status among those who matter morally.

A key working hypothesis in neuroscience is ‘materialistic reductionism’, i.e., the assumption whereby all physiological, behavioral or cognitive phenomena is produced by localized neurochemical brain activation (but not vice versa). However, analysis of sub-threshold Weber’s psychophysical stimulation indicates its computational irreducibility to the direct interaction between psychophysical stimulation and any neuron/s. This is because the materialistic-reductionistic working hypothesis assumes that the determination of the existence or non-existence of any psychophysical stimulation [s] may only be determined through its direct interaction (...) [di1] with a given neuron/s [N] that together forms the ‘neural registry’ computational level [NR/di1]. But, this implies that in cases of (initial) sub-threshold (sensory-specific) psychophysical stimulation which is increased above the sensory-specific threshold but below Weber’s psychophysical ‘dv’—the psychophysical computational processing [PCP] produces an apparently ‘computationally indeterminate’ output. This is because materialistic reductionism asserts the contingency of PCP upon the existence of a direct interaction between ‘s’ and ‘N’ within the NR/di1 level, but in the special case of Weber’s sub-threshold psychophysical stimulation the same PCP/di1 also asserts the non-existence of ‘s’ (as demanded by Weber’s psychophysical law). However, given robust empirical evidence indicating the capability of PCP to determine whether (or not) ‘s’ exists, we must conclude that PCP may not be carried out from within NR’s direct interaction between a particular psychophysical stimulation and any set of neuron/s in the brain. Hence, the Duality Principle asserts the conceptual irreducibility of sub-threshold psychophysical stimulation to any direct NR/di1: s-N interaction, thereby challenging the current materialistic-reductionistic assumption.

Birchley9s critique of the harm threshold for overriding parental decisions is successful in demonstrating that the harm threshold, like the best interests standard, suffers from the problem of indeterminacy. However, his focus on critiquing empirical rather than normative arguments for the harm threshold means that his broad conclusion that it is ‘ill-judged’ is not justified. Advocates of the harm threshold can accept that the concept of harm to a child is indeterminate, yet still invoke strong (...) normative arguments for this way of responding to parental decisions that conflict with medical recommendations. I suggest that Birchley9s discussion, rather than showing that the harm threshold is mistaken, instead highlights the importance of developing a comprehensive account of children9s interests, for proponents of a best interests approach and for advocates of the harm threshold.

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade‐offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find (...) that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold‐based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non‐decreasing thresholds. Decreasing threshold strategies that “front‐load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.

At present UK Law states that the unborn child only becomes a legal person invested with legal rights and full protections, like other human persons, at birth. This article critiques the present legal position of setting the threshold for legal personality at birth, showing its inconsistencies and fundamentally pragmatic basis. Against this background, it is argued that a principled approach towards unborn life is necessary, which reflects in law the reality that the unborn child is a type of human (...) person deserving protection as it develops through the continuum of human personhood – from embryonic personhood, to infant personhood and ultimately into adult personhood. Human personhood is defined as a union of a material and immaterial self, meaning that at every stage of their development they are never a “potential person,” but rather a “person with potential” even if it is not actualized through miscarriage, premature death, or disability. This moral and philosophical reasoning is what justifies protecting the sanctity of unborn life in law. The rest of the article explores and critiques the alternative static legal threshold for ascribing legal personality, at conception, implantation and viability. Having considered the practical moral, legal and philosophical problems of these alternatives; the final proposal for law reform combines all three of these thresholds in a proposal for a “dynamic” threshold for legal personality commencing at conception, which would render birth as an irrelevant threshold for moral and legal reasoning about the unborn.

A central puzzle of contemporary moral and political philosophy is that while most of us believe that all or almost all human beings enjoy the same moral status, human beings possess the capacities that supposedly ground moral status to very unequal levels. This paper aims to develop a novel strategy to vindicate the idea of moral equality against this challenge. Its central argument is that the puzzle emerges only if one accepts a usually unstated theoretical premise about value and the (...) proper response to value. The premise holds that if the presence of a valuable property warrants a certain kind of response towards its bearers, then every variation in the degree to which the property is present necessarily constitutes a reason for a corresponding variation in the response that is warranted towards its bearers. It argues that despite its intuitive appeal, the premise is not plausible as a general view about the proper way of responding to value, and as a view about responding to the value of rational beings in particular. It proposes an account of the proper manner of valuing rational beings that supports a distinctive version of the so-called threshold approach to justifying equal moral status. (shrink)

I resolve a previously unnoticed anomaly in the analysis of collective action problems. Some political theorists apply game theory to analyze the paradox of anarchy: War is apparently inevitable in anarchy even though all warring parties prefer peace over war. Others apply tipping threshold analysis to resolve the paradox of revolution: Joining a revolution is apparently always irrational even when an overwhelming majority of the population wish to replace their regime. The usual game theoretic analysis of anarchy yields the (...) conclusion that the suboptimal equilibrium of war is inevitable. The usual tipping threshold analysis of revolution yields the conclusion that the optimal equilibrium of successful revolution is possible. Yet structurally the collective action problems of anarchy and potential revolution are much the same. This suggests that tipping threshold analysis and game theory are incompatible methodologies, despite their widespread use in the social sciences. I argue that there is no real tension between game theory and tipping threshold analysis, even though these methodologies have developed largely independently of each other. I propose a Variable Belief Threshold model of collective action that combines elements of game theory and tipping threshold analysis. I show by example that one can use this kind of hybrid model to give compatible explanations of conflict in anarchy and successful revolution.1. Introduction2.

Mental-threshold egalitarianism, well-known examples of which include Jeff McMahan’s two-tiered account of the wrongness of killing and Tom Regan’s theory of animal rights, divides morally considerable beings into equals and unequals on the basis of their individual mental capacities. In this paper, I argue that the line that separates equals from unequals is unavoidably arbitrary and implausibly associates an insignificant difference in empirical reality with a momentous difference in moral status. In response to these objections, McMahan has proposed the (...) introduction of an intermediate moral status. I argue that this move ultimately fails to address the problem. I conclude that, if we are not prepared to give up moral equality, our full and equal moral status must be grounded in a binary property that is not a threshold property. I tentatively suggest that the capacity for phenomenal consciousness is such a property, and a plausible candidate. (shrink)

The threshold view says that a person forms an outright belief P if and only if her credence for P reaches a certain threshold.

A threshold view that performs well across diverse contexts is likely to be a cognitively (...) flexible and context-dependent fusion of several of the existing theories. The results of the simulations also cast doubts on the possibility of a threshold view that is both simple enough to streamline our reasoning while also allowing us to form good action-guiding beliefs.

The question I address in this paper is whether and under what conditions it is morally right to bring a person into existence. I defend the commonsensical thesis that, other things being equal, it is morally wrong to create a person who will be below some threshold of quality of life, even if the life of this potential person, once created, will nevertheless be worth living. However commonsensical this view might seem, it has shown to be problematic because of (...) the so-called 'Non-Identity Problem'. Both utilitarian and rights-based approaches have been unable to provide a solution to this problem. I rest my thesis on two premises: that causing a disability or impairment in a future person is prima facie wrong, so long as we can avoid causing such a disability to that very person; and that reproduction, under normal conditions, is prima facie morally indifferent. From these two premises, I conclude that it is prima facie wrong to bring into existence a person with a non-trivial disability or impairment (which might be, nonetheless, compatible with a worthwhile life), even if the only available alternative is to remain childless.

Recently, society and the accounting profession have become increasingly concerned with ethics. Accounting researchers have responded by attempting to investigate and analyze the ethical behavior of accountants. While the current state of ethical behavior among practitioners is important, the ability of accountants to detect ethical problems that may not be obvious should also be studied and understood. This study addresses three questions: (1) are auditors alert to ethical issues; (2) if so, how important do they perceive them to be; and (...) (3) what factors affect their sensitivity threshold and their perceptions of the importance of the issues?Most of the prior research in accounting ethics presents subjects with scenarios that contain an obvious ethical issue, and subjects realize that they are participating in an ethics study.

This study defines ethical sensitivity as the ability to interpret a given situation and to realize that a moral problem exists. (shrink)

McEntire (1984) proved that, for a portfolio problem with independent assets, the generalized harmonic mean plays the role of a risk-free threshold. Based upon this property, he developed a criterion for including or excluding assets in an optimal portfolio, and he proved an ordering theorem showing that an optimal portfolio always consists of positive amounts of the assets with the largest mean values. Also, some commonly used utility functions were shown to satisfy the property that the dominance of (...) an asset over another is unaffected by the addition of other assets. In this paper we extend these results to the case where assets are dependent. (shrink)
