Toward Unity among Environmentalists is Bryan Norton’s most developed effort to surmount the frequently intractable debate between anthropocentrists and nonanthropocentrists. Norton argues that the basic axiological differences between the two positions have become irrelevant at the level of policy formation. His thesis is that the two camps converge when dealing with practical goals and aims for environmental management. I argue that Norton’s approach falls significantly short of establishing such a convergence because of the overall methodological framework for policy formation (...) that he defends. The key problem with that framework is that it fails to provide for the degree of species protection most suitable to the nonanthropocentrist position. (shrink)

Although it could avoid some harmful effects of climate change, sulphate aerosol geoengineering (SAG), or injecting sulphate aerosols into the stratosphere in order to reflect incoming solar radiation, threatens substantial harm to humans and non-humans. I argue that SAG is prima facie ethically problematic from anthropocentric, animal liberationist, and biocentric perspectives. This might be taken to suggest that ethical evaluations of SAG can rely on Bryan Norton's convergence hypothesis, which predicts that anthropocentrists and non-anthropocentrists will agree to implement (...) the same or similar environmental policies. However, there are potential scenarios in which anthropocentrists and non-anthropocentrists would seem to diverge on whether a particular SAG policy ought to be implemented. This suggests that the convergence hypothesis should not be relied on in ethical evaluation of SAG. Instead, ethicists should consider the merits and deficiencies of both non-anthropocentric perspectives and the ethical evaluations of SAG such perspectives afford. (shrink)

Bryan Norton proposes a "convergence hypothesis'* stating that anthropocentrists and nonanthropocentrists can arrive at common environmental policy goals if certain constraints are applied. Within his theory he does not, however, address the consideration ofnonconsequentualist issues, and, therefore, does not provide an argument for the convergence between consequentualist and nonconsequentualist ethical positions. In the case of biotechnology, nonconsequentualist issues can dominate the debate in both the fields of environmental ethics and bioethics. I argue that, the convergence (...) class='Hi'>hypothesis must be rejected when tested against the case of biotechnology, and this limitation of convergence applies to any theory of reconciliation within the "health" concept because the achievement and preservation of "health "emphasizes a consequentualist outlook. I conclude that an inclusive ethics for ecosystem and human health should be explicit about this limitation. (shrink)

I propose a hypothesis, called the systems convergence-divergence hypothesis, which attempts to explain how the existence and evolution of supraindividual systems (social, political or economic) might be predicted from an analysis of the basic structures that make up their individual entities (molecules and cells) and how, reciprocally, study of these individuals and of their evolution might be approached from knowledge of such systems.

Evidence favors the nested sets hypothesis, introduced by fuzzy-trace theory (FTT) in the 1990s to explain effects and extended to many tasks, including conjunction fallacy, syllogistic reasoning, and base-rate effects (e.g., Brainerd & Reyna 1990; Reyna 1991; 2004; Reyna & Adam 2003; Reyna & Brainerd 1995). Crucial differences in mechanisms distinguish the FTT and Barbey & Sloman (B&S) accounts, but both contrast with frequency predictions (see Reyna & Brainerd, in press).

The convergence hypothesis asserts that, if one takes the full range of human values—present and future—into account, one will choose a set of policies that can also be accepted by an advocate of a consistent and reasonable nonanthropocentrism. Brian Steverson has attacked this hypothesis from a surprising direction. He attributes to deep ecologists the position that nonhuman nature has intrinsic value, interprets this position to mean that no species could ever be allowed to go extinct, and proceeds (...) to show that my commitment to contextualism prohibits me from advocating the protection of species universally. In response, I show, by reference to recent scientific findings, how difficult it is to defend species preservation in all situations. In particular, I argue that Steverson’s appeal to a possible world in which we have nearly complete biological knowledge misses the point of the convergence hypothesis. It is an empirical hypothesis, with significant indirect, and some direct, evidence to support it. Although it is a falsifiable hypothesis about realworld policies, it cannot be falsified by a contrary-to-fact case. (shrink)

Katie McShane, while accepting my 'convergence hypothesis' (the view that anthropocentrists and nonanthropocentrists will tend to propose similar policies), argues that nonanthropocentrism is nevertheless superior because it allows conservationists to have a deeper emotional commitment to natural objects than can anthropocentrists. I question this reasoning on two bases. First, McShane assumes a philosophically tendentious distinction between intrinsic and instrumental value – a distinction that presupposes a dualistic worldview. Second, I question why McShane believes anthropocentrists – weak anthropocentrists, that (...) is – cannot 'love' or 'feel awe' toward natural objects. Her argument, that is, only works against strong anthropocentrism, which I never advocated. (shrink)

Bryan Norton 's convergence hypothesis, which predicts that nonanthropocentric and human-based philosophical positions will actually converge on long-sighted, multi-value environmental policy, has drawn a number of criticisms from within environmental philosophy. In particular, nonanthropocentric theorists like J. Baird Callicott and Laura Westra have rejected the accuracy of Norton 's thesis, refusing to believe that his model's contextual appeals to a plurality of human and environmental values will be able adequately to provide for the protection of ecological integrity. These (...) theoretical criticisms of convergence, however, have made no real attempt to engage the empirical validity of the hypothesis, the dimension that Norton clearly takes to be the centerpiece of his project. Accordingly, the present paper attempts to provide an empirical analysis of the convergence argument, by means of a study of the Vermont public's environmental commitments and their attitudes toward national forest policy. Our findings support a generalized version of Norton 's thesis, and lead us to suggest that environmental philosophers should try to be more inclusive and empirically minded in their discussions about public moral claims regarding nature.

This study investigates the relationship among ethical philosophy, thinking style, and managerial ethical decision-making. Based on the premise that business ethics is a function of culture and time, we attempt to explore two important questions as to whether the national differences in managerial ethical philosophies remain over time and whether the relationship between thinking style and ethical decision-making is consistent across different national contexts. We conducted a survey on Korean managers’ ethical decision-making and thinking style and made a cross-cultural, cross-temporal (...) comparison with the results presented by previous studies that surveyed Korean and US managers with the same questionnaire at different points in time. Our analysis revealed that Korean managers have become more reliant on rule utilitarianism for ethical decision-making over the last two decades, which is dominantly used by US managers, corroborating our convergence hypothesis built on social contracts theory. However, as opposed to previous research, we found that managers with a balanced linear and nonlinear thinking style do not necessarily make more ethical decisions compared to those with a predominantly linear or nonlinear thinking style. This study contributes to international business ethics literature by presenting a theoretical framework that may explain the convergence of ethical philosophies employed by managers in different national contexts over time, and that the relationship between thinking style and managerial ethical decision-making may not be universal, but contingent on contextual factors.

Acoustic signals serving intraspecific communication by predators are perceived by potential prey as warning signals. We analysed the acoustic characteristics of howling of wolves and found a striking similarity to the warning sounds of technical sirens. We hypothesize that the effectivity of sirens as warning signals has been enhanced by natural sensory predisposition of humans to get alerted by howling of wolves, with which they have a long history of coexistence. Psychoacoustic similarity of both stimuli seems to be supported by (...) the fact that wolves and dogs perceive the sound of technical sirens as a relevant releasing supernormal stimulus and reply to it with howling. Inspiration by naturally occurring acoustic aposematic signals might become an interesting example of biomimetics in designing new warning sound systems. (shrink)

One construal of convergent realism is that for each clear question, scientific inquiry eventually answers it. In this paper we adapt the techniques of formal learning theory to determine in a precise manner the circumstances under which this ideal is achievable. In particular, we define two criteria of convergence to the truth on the basis of evidence. The first, which we call EA convergence, demands that the theorist converge to the complete truth "all at once". The second, which (...) we call AE convergence, demands only that for every sentence in the theorist's language, there is a time at which the theorist settles the status of the sentence. The relative difficulties of these criteria are compared for effective and ineffective agents. We then examine in detail how the enrichment of an agent's hypothesis language makes the task of converging to the truth more difficult. In particular, we parametrize first-order languages by predicate and function symbol arity, presence or absence of identity, and quantifier prefix complexity. For nearly each choice of values of these parameters, we determine the senses in which effective and ineffective agents can converge to the complete truth on an arbitrary structure for the language. Finally, we sketch directions in which our learning theoretic setting can be generalized or made more realistic. (shrink)

McCullough et al. argue that humans possess evolved computational systems for implementing retaliatory behavior that both deters aggression and promotes subsequent reconciliation. However, they do not apply this analysis to the sphere of intergroup relations. We believe their model can be usefully extended to this domain and discuss why this would be possible, pertinent, and productive.

In 'The Moral Problem', Michael Smith defends a conception of normative reasons that is nonrelative. Given his understanding of normative reasons, nonrelativity commits him to the convergence hypothesis: that, as a result of the process or correction of beliefs and rational deliberation, 'all' agents would converge on having the same set of desires. I develop several reasons for being pessimistic about the truth of this hypothesis. As a result, if normative reasons exist, we have a reason to (...) be skeptical of either Smith's understanding of what normative reasons are or of his insistence that they are nonrelative. (shrink)

This paper capitalizes on an institutional perspective to analyze corporate social responsibility (CSR) orientations in the Lebanese context. Specifically, the paper compiles a new theoretical framework drawing on a multi-level model of institutional flows by Scott (Institutions and organizations: ideas and interests, 2008 ) and the explicit/implicit CSR model by Matten and Moon (Acad Manag Rev 33(2):404–424, 2008 ). This new theoretical framework is then used to explore the CSR convergence versus divergence question in a developing country context. The (...) findings highlight the usefulness of the compiled multi-layered institutional framework and the varied nuances and profound insights it offers in analyzing CSR in context. They also suggest that a cosmetic level of global convergence in explicit CSR may materialize in light of mimetic isomorphic pressures, but that the path dependence hypothesis is indeed salient in light of national history trajectories and socio-politico configurations. The findings correspond most closely to patterns of CSR crossvergence, combining elements of both convergence and divergence, and reflecting in complex hybridized CSR expressions. The findings and their implications are presented and assessed. (shrink)

A range of themes—race and gender, sexuality, otherness, sisterhood, and agency—run throughout this collection, and the chapters constitute a collective discourse at the intersection of Black feminist thought and continental philosophy, converging on a similar set of questions and concerns. These convergences are not random or forced, but are in many ways natural and necessary: the same issues of agency, identity, alienation, and power inevitably are addressed by both camps. Never before has a group of scholars worked together to examine (...) the resources these two traditions can offer one another. By bringing the relationship between these two critical fields of thought to the forefront, the book will encourage scholars to engage in new dialogues about how each can inform the other. If contemporary philosophy is troubled by the fact that it can be too limited, too closed, too white, too male, then this groundbreaking book confronts and challenges these problems. -/- Table of Contents -/- Foreword Beverly Guy-Sheftall Acknowledgments Introduction: Black Feminism and Continental Philosophy Maria del Guadalupe Davidson, Kathryn T.

In other words, it is shown that we can test for convergent realism, just as readily (...) as Laudan can test for a connection between theories that are controlled by the cannons of science and their subsequent reliability.

In his political works, Thomas Hobbes proliferates arguments and overdetermines his conclusions. This article hypothesizes that at least some of this overdetermination was intentional. It was part of a “convergent strategy” meant to appeal to a broad, diverse, and unknown audience. The article draws on Leviathan to offer evidence for this hypothesis.

This model explores consensus among agents in a population in terms of two properties. The first is a probability of belief change. This value indicates how likely agents are to change their mind in interactions. The other is the size of the agents audience: the proportion of the population the agent has access to at any given time. In all instances, the agents converge on a single belief, although the agents are arational. I argue that this generates a skeptical (...) class='Hi'>hypothesis: any instance of purportedly rational consensus might just as well be a case of arational belief convergence. I also consider what the model tells us about increasing the likelihood that one agent’s belief is adopted by the rest. Agents are most likely to have their beliefs adopted by the entire population when their value for PBC is low relative to the rest of the population and their audience sizes are roughly three-quarters of the largest possible audience. I further explore the consequences of dogmatists to the population; individuals who refuse to change their mind end up polarizing the population. I conclude with reflections on the supposedly special character of rationality in belief-spread. (shrink)

Existing economic models of prosociality have been rather silent in terms of proximate psychological mechanisms. We nevertheless identify the psychologically most informed accounts and offer a critical discussion of their hypotheses for the proximate psychological explanations. Based on convergent evidence from several fields of research, we argue that there nevertheless is a more plausible alternative proximate account available: the social motivation hypothesis. The hypothesis represents a more basic explanation of the appeal of prosocial behavior, which is in terms (...) of anticipated social rewards. We also argue in favor of our own social motivation hypothesis over Robert Sugden’s fellow-feeling account (due originally to Adam Smith). We suggest that social motivation not only stands as a proximate account in its own right but also provides a plausible scaffold for other more sophisticated motivations (e.g., fellow-feelings). We conclude by discussing some possible implications of the social motivation hypothesis on existing modeling practice. (shrink)

In “A Confutation of Convergent Realism,” Larry Laudan presents the realist with these fascinating challenges:What,then,of realism itself as a ‘scientific’ hypothesis?…If realism has made some novel predictions or been subjected to carefully controlled tests, one does not learn about it from the literature of contemporary realism. (1981, p. 46.)He then goes on to say:No proponent of realism has sought to show that realism satisfies those stringent empirical demands which the realist himself minimally insists on when appraising scientific theories. (1981, (...) p. 46)Not only do I fully endorse what Laudan says in these passages, I think it is time to take him up on these challenges.Laudan’s position has been that scientific progress can be explained without having to appeal to verisimilitude. Instead, we explain the success of a scientific theory in terms of its subjugation to the cannons of experimental controls: those theories that have been put through proper testing during the course of their formulation are the ones that are most likely to be reliable.

The dominated convergence theorem implies that if is a sequence of functions on a probability space taking values in the interval [0, 1], and converges pointwise a.e., then converges to the integral of the pointwise limit. Tao [26] has proved a quantitative version of this theorem: given a uniform bound on the rates of metastable convergence in the hypothesis, there is a bound on the rate of metastable convergence in the conclusion that is independent of the (...) sequence and the underlying space. We prove a slight strengthening of Tao’s theorem which, moreover, provides an explicit description of the second bound in terms of the first. Specifically, we show that when the first bound is given by a continuous functional, the bound in the conclusion can be computed by a recursion along the tree of unsecured sequences. We also establish a quantitative version of Egorov’s theorem, and introduce a new mode of convergence related to these notions. (shrink)

Recent studies have provided evidence of associations between neurochemistry and reading (dis)ability (Pugh et al., 2014). Based on a long history of studies indicating that fluent reading entails the automatic convergence of the written and spoken forms of language and our recently proposed Neural Noise Hypothesis (Hancock et al., 2017), we hypothesized that individual differences in cross-modal integration would mediate, at least partially, the relationship between neurochemical concentrations and reading. Cross-modal integration was measured in 231 children using a (...) two-alternative forced choice cross-modal matching task with three language conditions (letters, words, and pseudowords) and two levels of difficulty within each language condition. Neurometabolite concentrations of Choline (Cho), Glutamate (Glu), gamma-Aminobutyric (GABA), and N- acetyl-aspartate (NAA) were then measured in a subset of this sample (n = 70) with Magnetic Resonance Spectroscopy (MRS). A structural equation mediation model revealed that the effect of cross-modal word matching mediated the relationship between increased Glu (which has been proposed to be an index of neural noise) and poorer reading ability. In addition, the effect of cross-modal word matching fully mediated a relationship between increased Cho and poorer reading ability. Multilevel mixed effects models confirmed that lower Cho predicted faster cross-modal matching reaction time, specifically in the hard word condition. These Cho... (shrink)

Wenmackers and Romeijn (2016) formalize ideas going back to Shimony (1970) and Putnam (1963) into an open-minded Bayesian inductive logic, that can dynamically incorporate statistical hypotheses proposed in the course of the learning process. In this paper, we show that Wenmackers and Romeijn’s proposal does not preserve the classical Bayesian consistency guarantee of merger with the true hypothesis. We diagnose the problem, and offer a forward-looking open-minded Bayesians that does preserve a version of this guarantee.

The claim that the disorganized subtype of schizophrenia results from glutamate hypofunction is enhanced by consideration of current subtypology of schizophrenia, symptom definition, interdependence of neurotransmitters, and the nature of the data needed to support the hypothesis. Careful specification clarifies the clinical reality of disorganization as a feature of schizophrenia and increases the utility of the subtype.

This paper synthesizes convergent lines of evidence to evaluate the hypothesis that objective falsity is essential to lying. Objective accounts of lying affirm this hypothesis; subjective accounts deny it. Evidence from history, logic, social observation, popular culture, lexicography, developmental psychology, inference, spontaneous description, and behavioral experimentation strongly supports the hypothesis. Studies show that the only apparent evidence against the hypothesis is due to task substitution, i.e. ethical concerns or perspective-taking interfering with performance on categorization tasks. I (...) conclude that, overall, existing evidence decisively favors objective accounts. (shrink)

As a working hypothesis for philosophy of science, the unity of science thesis has been decisively challenged in all its standard formulations; it cannot be assumed that the sciences presuppose an orderly world, that they are united by the goal of systematically describing and explaining this order, or that they rely on distinctively scientific methodologies which, properly applied, produce domain-specific results that converge on a single coherent and comprehensive system of knowledge. I first delineate the scope of arguments against (...) global unity theses. However implausible old-style global unity theses may now seem, I argue that unifying strategies of a more local and contingent nature do play an important role in scientific inquiry. This is particularly clear in archaeology where, to establish evidential claims of any kind, practitioners must exploit a range of inter-field and inter-theory connections. At the same time, the robustness of these evidential claims depends on significant disunity between the sciences from which archaeologists draw background assumptions and auxiliary hypotheses. This juxtaposition of unity with disunity poses a challenge to standard positions in the debate about scientific unity. (shrink)

Tacking by conjunction is a well-known problem for Bayesian confirmation theory. In the first section, disadvantages of existing Bayesian solution proposals to this problem are pointed out and an alternative solution proposal is presented: that of genuine confirmation. In the second section, the notion of GC is briefly recapitulated and three versions of GC are distinguished: full GC, partial GC and quantitative GC. In the third section, the application of partial GC to pure post-facto speculations is explained. In the fourth (...) section it is demonstrated that full GC is a necessary condition for Bayesian convergence to certainty based on the accumulation of conditionally independent pieces of evidence. It is found that whenever a hypothesis is equivalent to a disjunction of more fine-grained hypotheses conveying different probabilities to the evidence, then conditional independence of the evidence fails. This failure occurs typically for unspecific negations of hypotheses. A refined version of the convergence to certainty theorem that overcomes this difficulty is developed in the final section.

The hypothesis I develop involves that we have been witnessing, during the last ten years or so, an interpenetration in the area of applied ethics of certain concepts originally belonging to different areas of ethics, namely bioethics, environmental ethics, and also business ethics. Certain concepts such as “future generations,” “consent,” “precautionary principle,” “intrinsic value,” “global governance,” “sustainable development,” or “scientific uncertainty” are becoming “thick ethical concepts,” in the terminology of metaethics; or in the terminology of American pragmatism: “living beliefs.” (...) They are now charged with strong moral contents that unfolds a new horizon of meaning at the heart of Western Modernity, a horizon largely defined by science and technical actions. Nevertheless, is this conceptual convergence in the area of applied ethics the sign of the coming of a new ethic of technique? I will discuss this topic taking as an example the case of nanotechnology. (shrink)

This essay demonstrates a previously unnoticed connection between formal and statistical learning theory with regard to Nelson Goodman’s new riddle of induction. Discussions of Goodman’s riddle in formal learning theory explain how conjecturing “all green” before “all grue” can enhance efficient convergence to the truth, where efficiency is understood in terms of minimizing the maximum number of retractions or “mind changes.” Vapnik-Chervonenkis (VC) dimension is a central concept in statistical learning theory and is similar to Popper’s notion of degrees (...) of testability. I show that for a class inductive problems of which Goodman’s riddle is one example, a reliable inductive method minimizes the maximum number of mind changes exactly if it always conjectures the hypothesis from the set with lowest VC dimension consistent with the data. I also discuss the relevance of these results to language invariance and curve fitting. (shrink)

In spite of differences the thought of Bernays, Dooyeweerd and Gödel evinces a remarkable convergence. This is particularly the case in respect of the acknowledgement of the difference between the discrete and the continuous, the foundational position of number and the fact that the idea of continuity is derived from space (geometry – Bernays). What is furthermore similar is the recognition of what is primitive (and indefinable) as well as the account of the coherence of what is unique, such (...) as when Gödel observes something quasi-spatial character of sets. It is shown that Dooyeweerd’s theory of modal aspects provides a philosophical framework that exceeds his own restrictive understanding of infinity )to the potential infinite) and at the same time makes it possible to account for key insights found in the thought of Bernays and Gödel. When Laugwitz says that discreteness rules within the sphere of the numerical, he says nothing more than what Dooyeweerd had in mind with his idea that discrete quantity, as the meaning-nucleus of the arithmetical aspect, qualifies every element within the structure of the quantitative aspect. And when Bernays says that analysis expresses the idea of the continuum in arithmetical language his mode of speech is equivalent to saying that mathematical analysis could seen as being founded upon the spatial anticipation within the modal structure of the arithmetical aspect. The view of the actual infinite (the at once infinite) in terms of an “as if” approach (Bernays), that is, as appreciated as a regulative hypothesis through which every successively infinite multiplicity of numbers could be envisaged as being giving all at once, as an infinite totality, provides a sound understanding of the at once infinite and makes it plain why every form of arithmeticism fails. Such attempts have to call upon Cantor’s proof on the non-denumerability of the real numbers – and this proof pre-supposes the use of the at once infinite which, in turn, pre-supposes the (irreducibile) spatial order of simultaneity and the patial whole-parts relation.

Using a purposive sample with an even distribution of 299 non-Hispanic Whites, 294 African Americans, 292 Asian Americans and 295 Hispanics, we test a moderated mediation model that examines the relationship between self-reported news media consumption (e.g., non-conservative and conservative) and environmental behavioural intentions. Our study found evidence supporting the mainstreaming hypothesis (converging attitudes) across key variables within the theory of planned behaviour (TPB). Our results also reveal non-conservative outlets to be associated with more favourable environmental attitudes, subjective norms (...) and perceived behavioural control, while conservative outlets are associated with less favourable levels for two of these three variables. Results also indicate conditional indirect relationships between non-conservative news use on behavioural intentions through our TPB variables, which vary by race/ethnicity. (shrink)

This article, first of all, supports the idea that the undeniable process of ICT-based technological convergence implies the social, cultural and business unification of the world of media and culture.

Thirdly, a variety of new possible and realistically achievable professional profiles in cultural industries and institutions are illustrated. Eventually a set of public policies, in the light of a new role for cities and regions, is developed. (shrink)

This paper provides an empirical defense of credit theories of knowing against Mark Alfano’s challenges to them based on his theses of inferential cognitive situationism and of epistemic situationism.

Numerous studies have convincingly shown that prospect theory can better describe risky choice behavior than the classical expected utility model because it makes the plausible assumption that risk aversion is driven not only by the degree of sensitivity toward outcomes, but also by the degree of sensitivity toward probabilities. This article presents the results of an experiment aimed at testing whether agents become more sensitive toward probabilities over time when they repeatedly face similar decisions, receive feedback on the consequences of (...) their decisions, and are given ample incentives to reflect on their decisions, as predicted by Plott’s Discovered Preference Hypothesis (DPH). The results of a laboratory experiment with N = 62 participants support this hypothesis. The elicited subjective probability weighting function converges significantly toward linearity when respondents are asked to make repeated choices and are given direct feedback after each choice. Such convergence to linearity is absent in an experimental treatment where respondents are asked to make repeated choices but do not experience the resolution of risk directly after each choice, as predicted by the DPH.

A model of inductive inquiry is defined within the context of first‐order logic. The model conceives of inquiry as a game between Nature and a scientist. To begin the game, a nonlogical vocabulary is agreed upon by the two players, along with a partition of a class of countable structures for that vocabulary. Next, Nature secretly chooses one structure from some cell of the partition. She then presents the scientist with a sequence of facts about the chosen structure. With each (...) new datum the scientist announces a guess about the cell to which the chosen structure belongs. To succeed in his or her inquiry, the scientist’s successive conjectures must be correct all but finitely often, that is, the conjectures must converge in the limit to the correct cell. Different kinds of scientists can be investigated within this framework. At opposite ends of the spectrum are dumb scientists that rely on the strategy of “induction by enumeration,” and smart scientists that rely on an operator of belief revision. We report some results about the scope and limits of these two inductive strategies. (shrink)

With each (...) new datum the scientist announces a guess about the cell to which the chosen structure belongs. To succeed in his or her inquiry, the scientist’s successive conjectures must be correct all but finitely often, that is, the conjectures must converge in the limit to the correct cell. Different kinds of scientists can be investigated within this framework. At opposite ends of the spectrum are dumb scientists that rely on the strategy of “induction by enumeration,” and smart scientists that rely on an operator of belief revision. We report some results about the scope and limits of these two inductive strategies. (shrink)

Urban street trees (USTs) have a range of values – some of which are easier to quantify than others. Focusing specifically on the UK context and using the Sheffield Tree Protests (2012–) as a case study, whilst confirming existing research as to the variety of values associated with their specifically ‘cultural’ services, the article argues that USTs have an additional potential form – what I call ‘civic-transformative value’. This form of value has at least three key characteristics. Firstly, it is (...) place-based and communal; second, its form is ‘relational’; and finally, as intrinsically contingent, it is pluralistic in the sense that its civic-transformative potential is dependent on successfully integrating a range of other values. The article emphasises both the possibility and necessity of ‘convergence’ – that is, a pluralistic and pragmatic alliance of values which might help protect not only USTs, but other embattled sites of nature.

Using Reidenbach and Robin‘s ( Journal of Business Ethics 7, 871–879, 1988) multi-criteria ethics instrument, we carried out the first empirical test of Robertson and Crittenden‘s (Strategic Management Journal 24, 385–392, 2003) cross-cultural map of moral philosophies to examine what ethical criteria guide business people in Russia and the U.S. in their intention to behave. Competing divergence and convergence hypotheses were advanced. Our results support a convergence hypothesis, and reveal a common emphasis on relativism. Americans are also (...) influenced by the justice criterion while Russians tend to emphasize utilitarianism. (shrink)

Many people who claim to genuinely care about nature still seem reluctant to ascribe intrinsic value to it. Environmentalists, nature friendly people in general, and even environmental activists, often hesitate at the idea that nature possesses value in its own right—value that is not reducible to its importance to human or other sentient beings. One crucial explanation of this reluctance is probably the thought that such value—at least when attached to nature—would be mysterious in one way or another, or at (...) least very difficult to account for. In addition, Bryan Norton’s influential convergence hypothesis states that, from a practical point of view, it makes no or little difference whether we ascribe intrinsic value to nature, given the depth and variety of instrumental value it possesses. In this paper, I argue that people who genuinely care about nature cannot avoid ascribing intrinsic value (in a certain sense) to it, if they want to be able to consistently defend the kind of claims about protecting nature they arguably want to make, i.e., claims to the effect that we ought to protect for instance nature areas and species. The cost of denying intrinsic value in nature is the cost of giving up a crucial resource to philosophically defend such claims. (shrink)

Many recent critical discussions of anthropocentrism have focused on Bryan Norton's 'convergence hypothesis': the claim that both anthropocentric and nonanthropocentric ethics will recommend the same environmentally responsible behaviours and policies. I argue that even if we grant the truth of Norton's convergence hypothesis, there are still good reasons to worry about anthropocentric ethics. Ethics legitimately raises questions about how to feel, not just about which actions to take or which policies to adopt. From the point of (...) view of norms for feeling, anthropocentrism has very different practical implications from nonanthropocentrism; it undermines some of the common attitudes - love, respect, awe - that people think it appropriate to take toward the natural world.

I address the issue of whether differences in ethical theory have any relevance for the practical issues of environmental management and policy making. Norton’s answer, expressed as a convergence hypothesis, is that environmentalists are evolving toward a consensus in policy even though they remain divided regarding basic values. I suggest that there are good reasons for rejecting Norton’s position.I elaborate on these reasons, first, by distinguishing between different forms of anthropocentrism and nonanthropocentrism, second, by contrasting the different goals (...) that anthropocentrists, biocentrists, and ecocentrists set up for environmental policy making, and, lastly, by identifying three important policy areas (population growth, wilderness preservation, and wildlife management) where differences in basic values generate divergent policies.
