GREGORY MIKKELSON | : Animal and environmental ethics should converge on the following three value judgments: natural ecosystems generally involve more good than harm; predation in nature tends to yield positive net benefits; and, at least on a global scale, livestock farming is destroying more value than it is creating. But the ecocentric criteria of environmental ethics and the sentientist criteria of animal ethics may have divergent implications for capitalism’s main effect on the world: the collapse of wild (...) nature due to explosive growth in the human economy. Sentientism risks counting this effect as a net gain, whereas ecocentrism surely rates it a massive net loss. While supporting the above claims, I show how they fit into a larger argument in favour of the broader, ecocentric value theory of environmental ethics and against the narrower, sentientist axiology of animal ethics. | : Les éthiques animale et environnementale devraient converger vers les trois jugements de valeur suivants: les écosystèmes naturels impliquent généralement plus de bien que de mal, la prédation dans la nature a tendance à produire des avantages nets positifs et, au moins à l’échelle mondiale, l’élevage animal détruit plus de valeur qu’il n’en crée. Mais les critères écocentriques de l’éthique environnementale et les critères de l’éthique animale fondés sur la sentience pourraient avoir des implications divergentes sur l’effet principal du capitalisme sur le monde: l’effondrement de la nature sauvage dû à la croissance explosive de l’économie humaine. Le sentientisme risque de considérer cet effet comme un gain net, alors que l’écocentrisme le considère sûrement comme une perte nette massive. Tout en soutenant les affirmations ci-dessus, je montre comment elles s’intègrent dans un argument plus large en faveur d’une théorie de la valeur écocentrique plus englobante propre à l’éthique environnementale et contre l’axiologie sentientiste plus étroite de l’éthique animale.

The mass extinction visited upon us by capitalism involves many kinds of devastation. Here I clarify the grounds for assessing the most obvious of these harms, i.e., decimation of species diversity. The thesis that variety among species has intrinsic value motivates, and in turn follows from, the “variable value view” (VVV) of abundance within any given species. In contrast, standard axiologies have no place for the intrinsic value of species diversity. I show that the VVV provides a better justification than (...) the latter do, of the way in which a widely-used empirical indicator summarizes the overall state of life on Earth. These considerations favor ecocentric value theory – which ascribes intrinsic value to properties of ecological wholes, like species diversity, that do not supervene on the well-being of their constituent organisms – over its main competitors. I conclude by widening the focus from wild nature alone to the biosphere comprising both wilderness and the domesticated realm. This broadened perspective helps to link the science and ethics of biodiversity with the political struggle to extract ourselves from the moral abyss of mass extinction. (shrink)

Richness theory offers an alternative to the paradigms that have dominated the short history of environmental ethics as a self-conscious field. This alternative theoretical paradigm defines intrinsic value as “richness”—a synonym for “organic unity” or “unity in diversity.” Richness theory can handily reconcile two kinds of ideas that seem to be in tension with each other:that (1) an individual human being has a greater worth than an individual organism of just about any other species; and (2) yet the world would (...) be a better place with substantially fewer humans and/or less consumption per capita, thus leaving more resources for other species.The mutual compatibility of such ideas within the framework of richness theory can be demonstrated both verbally and through a simplified mathematical model.

Lewis' argument against the Limit Assumption and Pollock's Generalized Consequence Principle together suggest that "minimal-change" theories of counterfactuals are wrong. The "small-change" theories presented by Nute do not say enough. While these theories rely on closeness between possible worlds, I base an alternative on the ceteris paribus concept. My theory solves a problem that the above cannot, and is more relevant to the philosophy of science. Ceteris paribus conditions should normally include the causes, but exclude the effects, of the negated (...) antecedent. An example from community ecology, the debate over null models in island-biogeographical studies of competition, supports these arguments. (shrink)

Scientists must sometimes choose between competing definitions of key terms. The degree to which different definitions facilitate important discoveries should ultimately guide decisions about which terms to accept. In the short run, rules of thumb can help. One such rule is to regard with suspicion any definition that turns a seemingly important empirical matter into an a priori exercise. Several prominent definitions of ecological “stability” are suspect, according to this rule. After evaluating alternatives, I suggest that the faulty definitions resulted (...) from an overemphasis on population dynamics in community ecology. Machine metaphors of nature may have given rise to a related problem of experimental design. (shrink)

Richness theory offers a promising axiology. In this paper, I discuss how to translate it into a deontology. To do so, I recruit the concept of moral distance from a recently developed epistemology, and construe it in terms of causal power. Finally, I apply the resulting decision-theoretic framework to the question of how best to avert ecological disaster over the next 36 years and achieve ecological harmony over the next 986.

Ecologists typically invoke "law-like" generalizations, ranging over "structural" and/or "functional" kinds, in order to explain generalizations about "historical" kinds (such as biological taxa)rather than vice versa. This practice is justified, since structural and functional kinds tend to correlate better with important ecological phenomena than do historical kinds. I support these contentions with three recent case studies. In one sense, therefore, ecology is, and should be, more nomothetic, or law-oriented, than idiographic, or historically oriented. This conclusion challenges several recent philosophical claims (...) about the nature of ecological science. (shrink)

In this paper, I offer a new defense of scientific realism, tailored for the Akaikean paradigm of statistical hypothesis testing. After proposing definitions of verisimilitude and predictive success, I use computer simulations to show how the latter depends on the former, even in the kind of case featured in a recent argument for instrumentalism.

When data are limited, simple models of complex ecological systems tend to wind up closer to the truth than more complex models of the same systems. This greater proximity to the truth, or verisimilitude, leads to greater predictive success. When more data are available, the advantage of simplicity decreases, and more complex models may gain the upper hand. In ecology, holistic models are usually simpler than reductionistic models. Thus, when data are limited, holistic models have an advantage over reductionistic models, (...) with respect to verisimilitude and predictive success. I illustrate these points with models designed to explain and predict the numbers of species on islands. (shrink)

Robert MacArthur's mathematical ecology is often regarded as ahistorical and has been criticized by historically oriented ecologists and philosophers for ignoring the importance of history. I clarify and defend his approach, especially his use of simple mathematical models to explain patterns in data and to generate predictions that stimulate empirical research. First I argue that it is misleading to call his approach ahistorical because it is not against historical explanation. Next I distinguish three kinds of criticism of his approach and (...) argue that his approach is compatible with the first two of them. Finally, I argue that the third kind of criticism, advanced by Kim Sterelny and Paul Griffiths, is largely irrelevant to MacArthur's approach. ‡I am especially grateful to Thomas Nickles for encouragement and helpful comments on earlier versions of this paper. Thanks also to Guy Hoelzer, Stephen Jenkins, and Jay Odenbaugh for comments on an earlier draft, Kim Sterelny for clarifications of the Tasmania example, Gregory Mikkelson for references, and the audience at PSA 2006 for discussions. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e-mail: [email protected].

Biologists study life in its various physical forms, while philosophers of biology seek answers to questions about the nature, purpose, and impact of this research. What permits us to distinguish between living and nonliving things even though both are made of the same minerals? Is the complex structure of organisms proof that a creative force is working its will in the physical universe, or are existing life-forms the random result of an evolutionary process working itself out over eons of time? (...) What moral and social questions arise regarding modern advances in biotechnology? What is more relevant to human nature: genetics or sociocultural influences? Is Darwinism the death-knell of God? These are just some of the vital questions addressed by a distinguished group of philosophers and scientists which includes: Aristotle, Francisco J. Ayala, , Michael Benton, Tom Bethell, Joe Cain, David Castle, Charles Darwin, Richard Dawkins, Michael Denton, A.G.N. Flew, Stephen Jay Gould, J.B.S. Haldane, John F. Haught, D. W. E. Hone, James W.

Richards, Mark Ridley, Holmes Rolston III, Michael Ruse, Lee Silver, Elliott Sober, Kim Sterelny, Derek Turner, and Edward O. Wilson. This second edition contains material on design without selection, testing macroevolutionary claims, recent biotechnological issues, key ecological concerns, the Gaia hypothesis, genetically modified foods, and the so-called intelligent design movement.

The article examines the effects of non-financial disclosure on corporate social responsibility. We conceptualise trade-offs between two ideal types in relation to CSR. Whereas self-regulation is associated with greater flexibility for businesses to develop best practices, it can also lead to complacency if firms feel no external pressure to engage with CSR. In contrast, government regulation is associated with greater stringency around minimum standards, but can also result in rigidity owing to a ‘one-size-fits-all’ approach. Given these potential trade-offs, we ask (...) how mandatory non-financial disclosure has been shaping CSR practices and examine its potential effectiveness as a regulatory instrument. Our analysis of 24 OECD countries using the Asset4 database shows that firms in countries that require non-financial disclosure adopt significantly more CSR activities. However, we also find that NFD regulation does not lead to lower levels of corporate irresponsibility. Furthermore, our analysis demonstrates that, over time, the variation in CSR activities declines as firms adopt increasingly similar practices. Our study thereby contributes to understanding the impact of government regulation on CSR at firm level. We also discuss the limits of mandatory NFD in addressing regulatory trade-offs between stringency and flexibility in the field of corporate social responsibility. (shrink)

The field of of imprecise probability has matured, in no small part because of Teddy Seidenfeld’s decades of original scholarship and essential contributions to building and sustaining the ISIPTA community. Although the basic idea behind imprecise probability is (at least) 150 years old, a mature mathematical theory has only taken full form in the last 30 years. Interest in imprecise probability during this period has also grown, but many of the ideas that the mature theory serves can be difficult to (...) apprehend to those new to the subject. Although these fundamental ideas are common knowledge in the ISIPTA community, they are expressed, when they are expressed at all, obliquely, over the course of years with students and colleagues. -/- A single essay cannot convey the store of common knowledge from any research community, let alone the ISIPTA community. But, this essay nevertheless is an attempt to guide those familiar with the basic Bayesian framework to appreciate some of the elegant and powerful ideas that underpin the contemporary theory of lower previsions, which is the theory that most people associate with the term ‘imprecise probabilities’.

The possibility of supererogation--doing more than one feels morally obliged to do--is denied by many thinkers.

In this paper I consider the prospects for a skeptical version of infallibilism. For the reasons given above, I think skeptical invariantism has a lot going for it. However, a satisfactory theory of knowledge must account for all of our desiderata, including that our ordinary knowledge attributions are appropriate. This last part will not be easy for the infallibilist invariantist. Indeed, I will argue that it is much more difficult than those sympathetic to skepticism have acknowledged, as there are serious (...) problems with regarding paradigmatic, typical knowledge attributions as loose talk, exaggerations, or otherwise practical uses of language. So, I do not think the pragmatic story that skeptical invariantism needs is one that works without a supplemental error theory of the sort left aside by purely pragmatic accounts of knowledge attributions. In its place, I will offer a compromise pragmatic and error view that I think delivers everything that skeptics can reasonably hope to get. (shrink)

This essay presents results about a deviation from independence measure called focused correlation . This measure explicates the formal relationship between probabilistic dependence of an evidence set and the incremental confirmation of a hypothesis, resolves a basic question underlying Peter Klein and Ted Warfield's ‘truth-conduciveness’ problem for Bayesian coherentism, and provides a qualified rebuttal to Erik Olsson's claim that there is no informative link between correlation and confirmation. The generality of the result is compared to recent programs in Bayesian epistemology (...) that attempt to link correlation and confirmation by utilizing a conditional evidential independence condition. Several properties of focused correlation are also highlighted.

That a philosophical thesis entails a vicious regress is commonly taken to be decisive evidence that the thesis is false. In this paper, I argue that the existence of a vicious regress is insufficient to reject a proposed analysis provided that certain constraints on the analysis are met. When a vicious regress is present, some further consequence of the thesis must be established that, together with the presence of the vicious regress, shows the thesis to be false. The argument is (...) provided largely through the examination of Michael Bergmann's vicious regress argument against strong awareness internalism and a partial defense of that thesis against Bergmann.

Growing concern with the panpsychist's ostensive inability to solve the ‘combination problem’ has led some authors to adopt a view titled ‘Cosmopsychism’. This position turns panpsychism on its head: rather than many tiny atomic minds, there is instead one cosmos-sized mind. It is supposed that this view voids the combination problem, however I argue that it does not. I argue that there is a ‘de-combination problem’ facing the cosmopsychist, which is equivalent to the combination problem as they are both concerned (...) with subjects being proper parts of other subjects. I then propose two methods for both theorists to avoid the problem of subject-subject proper parthood relations: a distinction between absolute and relative phenomenal unity, and a modification of the essential nature of subjects. Of these two options, I find the latter option wanting and propose that the first should be adopted. (shrink)

Catholic Social Teaching takes a rather cautious view toward the value of the ideas of Adam Smith, due to his emphasis on negative political and economic liberty. Detractors of Smith within CST point to what they consider to be deficiencies within his works: an impoverished moral anthropology, a lack of concern for the common good, and markets untethered to human needs. Defenders of Smith within CST tend to emphasize the material benefits that derive from Smithian institutions, such as economic growth, (...) improvements in standards of living, and the new opportunities that arise from cultures focused on innovation. This paper argues that Smith’s ideas have real value for CST. However, this value primarily lies in his moral psychology. While not denying the dangers of business activity for our moral lives, Smith also helps us to understand the possibility of the moral corruption of those who wield political power, thus providing an indirect defense of political and economic liberty that coheres with important Christian ethical notions found in CST. This is the case even though CST does not consistently recognize concerns surrounding the dangers of wielding political power—and thus Smith’s arguments offer real challenges to CST as well. This paper further suggests that these basic insights are relevant regardless of one’s favored institutional arrangements. (shrink)

Many philosophers think that part of what makes an event lucky concerns how probable that event is. In this paper, I argue that an epistemic probability account of luck successfully resists recent arguments that all theories of luck, including probability theories, are subject to counterexample (Hales 2016). I argue that an event is lucky if and only if it is significant and sufficiently improbable. An event is significant when, given some reflection, the subject would regard the event as significant, and (...) the event’s epistemic probability, determined by the subject’s evidence, is the only kind of probability that directly bears on whether or not the event is lucky. I conclude with some lessons that are applicable to probability theorists of luck generally, including those defending non-epistemic probability theories. (shrink)

In the age of big data and a machine epistemology that can anticipate, predict, and intervene on events in our lives, the problem once again is that a few individuals possess the knowledge of how to regulate these activities. But the question we face now is not how to share such knowledge more widely, but rather of how to enjoy the public benefits bestowed by this knowledge without freely sharing it. It is not merely personal privacy that is at stake (...) but a range of unsung benefits that come from ignorance and forgetting, traits that are inherently human and integral to the functioning of our society.

Philip Goff has recently argued that due to the ‘subject-summing problem’, panpsychism cannot explain consciousness. The subject-summing problem is a problem which is analogous to the physicalist's explanatory gap; it is a gap between the micro-experiential facts and the macro-experiential facts. Goff also suggests that there could be a solution by way of a ‘phenomenal bonding relation’, but believes that this solution is not up to scratch because we cannot form a positive not-merely-role-playing concept of this relation. In this paper, (...) I argue that the phenomenal bonding solution is up to scratch. I argue that the panpsychist, by carefully inspecting their phenomenology and scrutinising their concepts, can form a positive concept of the phenomenal bonding relation. By doing this they can start to get around their explanatory gap. (shrink)

We examine the notion of conditionals and the role of conditionals in inductive logics and arguments. We identify three mistakes commonly made in the study of, or motivation for, non-classical logics. A nonmonotonic consequence relation based on evidential probability is formulated. With respect to this acceptance relation some rules of inference of System P are unsound, and we propose refinements that hold in our framework.

The desirable gambles framework offers the most comprehensive foundations for the theory of lower pre- visions, which in turn affords the most general ac- count of imprecise probabilities. Nevertheless, for all its generality, the theory of lower previsions rests on the notion of linear utility. This commitment to linearity is clearest in the coherence axioms for sets of desirable gambles. This paper considers two routes to relaxing this commitment. The first preserves the additive structure of the desirable gambles framework and (...) the machinery for coherent inference but detaches the interpretation of desirability from the multiplicative scale invariance axiom. The second strays from the additive combination axiom to accommodate repeated gambles that return rewards by a non-stationary processes that is not necessarily additive. Unlike the first approach, which is a conservative amendment to the desirable gambles framework, the second is a rad- ical departure. Yet, common to both is a method for describing rewards called discounted utility. (shrink)

In this paper, I explain the curious role played by the Argument from Absolute Terms in Peter Unger's book Ignorance, I provide a critical presentation of the argument, and I consider some outstanding issues and the argument’s contemporary significance.

In this paper, I argue for the ethics of business based on the way that business activity may embody a vocation to partake in “the Good.” Following a Platonist framework for ethics and recent work on vocations by Robert M. Adams, I argue that understanding the ethics of vocations allows us to avoid the charges that business persons have to do something more for others—often couched in terms of social responsibility, sustainability, or consideration of stakeholders—in order to legitimize their careers (...) ethically. Rather, I claim, the ethics of a business vocation, as in any vocation, rests first and foremost in the way that a person pursues projects that answer an invitation to partake in the good things of this world. Thus, the promotion of the well-being of others, while ethically admirable and constitutive of some vocations, is not fundamental for understanding the ethics of vocations themselves, even in business. There are important implications for the ethics of markets, and I also consider a recent challenge to my approach that claims that true business vocations demand a more direct promotion of the well-being of others.

This paper presents statistical default logic, an expansion of classical (i.e., Reiter) default logic that allows us to model common inference patterns found in standard inferential statistics, including hypothesis testing and the estimation of a populations mean, variance and proportions. The logic replaces classical defaults with ordered pairs consisting of a Reiter default in the first coordinate and a real number within the unit interval in the second coordinate. This real number represents an upper-bound limit on the probability of accepting (...) the consequent of an applied default and that consequent being false. A method for constructing extensions is then defined that preserves this upper bound on the probability of error under a (skeptical) non-monotonic consequence relation. (shrink)

Logic is a celebrated representation language because of its formal generality. But there are two senses in which a logic may be considered general, one that concerns a technical ability to discriminate between different types of individuals, and another that concerns constitutive norms for reasoning as such. This essay embraces the former, permutation-invariance conception of logic and rejects the latter, Fregean conception of logic. The question of how to apply logic under this pure invariantist view is addressed, and a methodology (...) is given. The pure invariantist view is contrasted with logical pluralism, and a methodology for applied logic is demonstrated in remarks on a variety of issues concerning non-monotonic logic and non-monotonic inference, including Charles Morgan’s impossibility results for non-monotonic logic, David Makinson’s normative constraints for non-monotonic inference, and Igor Douven and Timothy Williamson’s proposed formal constraints on rational acceptance.

Spengler’s work is typically represented as speculative philosophy of history. However, I argue that there is good reason to consider much of his thought as preoccupied with existential and phenomenological questions about the nature and ends of human existence, rather than with history per se. In this paper I consider Spengler’s work in comparison with Heidegger’s history of Being and analysis of technological modernity. I argue that Spengler’s considerable proximity to much of Heidegger’s thought compels us to reconsider the nature (...) and scope of Spengler’s philosophical project. (shrink)

Positions in the debate about the correct semantics of “S knows that p” are sometimes motivated in part by an appeal to interpretive charity. In particular, non-skeptical views hold that many utterances of the sentence “S knows that p” are true and some of them think the fact that their views are able to respect this is a reason why their views are more charitable than skeptical invariantism. However, little attention has been paid to why charity should be understood in (...) this way and little effort has been spent justifying the notion that a charitable semantics is likely to be true. I distinguish two kinds of interpretive charity. One principle of charity is often appealed to in the literature. I introduce a second. I argue that while some positions better respect one principle of charity, the reverse is true of the other principle of charity. I conclude with some remarks about how to break this apparent tie.

Hilbert’s unpublished 1917 lectures on logic, analyzed here, are the beginning of modern metalogic. In them he proved the consistency and Post-completeness (maximal consistency) of propositional logic -results traditionally credited to Bernays (1918) and Post (1921). These lectures contain the first formal treatment of first-order logic and form the core of Hilbert’s famous 1928 book with Ackermann. What Bernays, influenced by those lectures, did in 1918 was to change the emphasis from the consistency and Post-completeness of a logic to its (...) soundness and completeness: a sentence is provable if and only if valid. By 1917, strongly influenced by PM, Hilbert accepted the theory of types and logicism -a surprising shift. But by 1922 he abandoned the axiom of reducibility and then drew back from logicism, returning to his 1905 approach of trying to prove the consistency of number theory syntactically. (shrink)

In this paper I look at a recent proposal from Yujin Nagasawa and Khai Wager to avoid the de-combination problem for the view called ‘cosmopsychism’. The pair suggest that the de-combination problem can be solved in the same way that the problem of heterogeneity for Schaffer’s priority monism can be solved. I suggest that this is not the case. They are not the same problem and the solutions to the heterogeneity problem do not work for the de-combination problem.
