Despite concerns of consumer protection andenvironmental groups that the use of geneticallyproduced growth hormone in milk-producing cows mayadversely impact the safety of the milk supply,scientific evidence and governmental findings from theUSA appear to indicate that milk fromtreated cows is identical in quality, taste, andnutritional value to milk from untreated cows. Limitedexperience to date in the USA demonstrateslittle consumer resistance to milk from cows that havereceived the growth hormone, which can lead to a 15%increase in milk production. In fact, if there (...) is noperceived differentiation between the two forms ofmilk, the issue offers little choice to consumers atlarge, and may result in economic benefit only toselected dairy farmers, as well as the producers ofthe genetically produced growth hormone. Thissituation in the USA may be an example ofdysfunctional technology transfer, with desirablebenefits to a few, and as yet unknown benefits to thesociety. The USA has taken a bold move inapproving the use of bovine growth hormone in milk-producing cows, while the European Union has takena divergent approach by enacting lengthy moratoriumsagainst its use. The basic lesson to be learned fromthe bST case is that lack of awareness amonggovernment officials and the public at large serves asa significant impediment to the adoption of newtechnologies. Accordingly, delays may occur indelivery of significant social benefits to thepopulation as a whole. Obviously, the issue extendsbeyond bST. (shrink)

If the world itself is metaphysically indeterminate in a specified respect, what follows? In this paper, we develop a theory of metaphysical indeterminacy answering this question.

How do thought and language manage to be 'about' aspects of the world? J. Robert G. Williams investigates how representation arises out of a fundamentally non-representational world, showing the explanatory relations between the representational properties of language, of thought, and of perception and intention.

Decisions are made under uncertainty when there are distinct outcomes of a given action, and one is uncertain to which the act will lead. Decisions are made under indeterminacy when there are distinct outcomes of a given action, and it is indeterminate to which the act will lead. This paper develops a theory of (synchronic and diachronic) decision-making under indeterminacy that portrays the rational response to such situations as inconstant. Rational agents have to capriciously and randomly choose how to resolve (...) the indeterminacy relevant to a given choice-situation, but such capricious choices once made constrain how they will choose in the future. The account is illustrated by the case of self-interested action in situations where it is indeterminate whether you yourself will survive to benefit or suffer the consequences. The conclusion emphasizes some distinctive anti-hedging predictions of the account. (shrink)

Might it be that world itself, independently of what we know about it or how we represent it, is metaphysically indeterminate? This article tackles in turn a series of questions: In what sorts of cases might we posit metaphysical indeterminacy? What is it for a given case of indefiniteness to be 'metaphysical'? How does the phenomenon relate to 'ontic vagueness', the existence of 'vague objects', 'de re indeterminacy' and the like? How might the logic work? Are there reasons for postulating (...) this distinctive sort of indefiniteness? Conversely, are there reasons for denying that there is indefiniteness of this sort? (shrink)

Inscrutability arguments threaten to reduce interpretationist metasemantic theories to absurdity. Can we find some way to block the arguments? A highly influential proposal in this regard is David Lewis’ ‘ eligibility ’ response: some theories are better than others, not because they fit the data better, but because they are framed in terms of more natural properties. The purposes of this paper are to outline the nature of the eligibility proposal, making the case that it is not ad hoc, but (...) instead flows naturally from three independently motivated elements; and to show that severe limitations afflict the proposal. In conclusion, I pick out the element of the eligibility response that is responsible for the limitations: future work in this area should therefore concentrate on amending this aspect of the overall theory.

In the management and business ethics literatures, stakeholder engagement has been demonstrated to lead to more ethical management practices. However, there may be limits on the extent to which stakeholder engagement can, as currently conceptualized, resolve some of the more difficult ethical challenges faced by managers. In this paper we argue that stakeholder engagement, when seen as a way of reducing five types of knowledge problems—risk, ambiguity, complexity, equivocality, and a priori irreducible uncertainty—can aid managers in resolving such ethical challenges. (...) Using a practical illustration of the ethical challenges surrounding the development and application of genetic modification technologies, we demonstrate how stakeholder engagement enables managers to better address these knowledge problems, thereby to manage more ethically. In this way, we suggest that stakeholder engagement has an even more crucial role to play in business ethics research and practice. (shrink)

Lewis (1973) gave a short argument against conditional excluded middle, based on his treatment of ‘might’ counterfactuals. Bennett (2003), with much of the recent literature, gives an alternative take on ‘might’ counterfactuals. But Bennett claims the might-argument against CEM still goes through. This turns on a specific claim I call Bennett’s Hypothesis. I argue that independently of issues to do with the proper analysis of might-counterfactuals, Bennett’s Hypothesis is inconsistent with CEM. But Bennett’s Hypothesis is independently objectionable, so we should (...) resolve this tension by dropping the Hypothesis, not by dropping CEM. (shrink)

Worlds where things divide forever ("gunk" worlds) are apparently conceivable. The conceivability of such scenarios has been used as an argument against "nihilist" or "near-nihilist" answers to the special composition question. I argue that the mereological nihilist has the resources to explain away the illusion that gunk is possible.

Revisionary theories of logic or truth require revisionary theories of mind. This essay outlines nonclassically based theories of rational belief, desire, and decision making, singling out the supervaluational family for special attention. To see these nonclassical theories of mind in action, this essay examines a debate between David Lewis and Derek Parfit over what matters in survival. Lewis argued that indeterminacy in personal identity allows caring about psychological connectedness and caring about personal identity to amount to the same thing. The (...) essay argues that Lewis's treatment of two of Parfit's puzzle cases—degreed survival and fission—presuppose different nonclassical treatments of belief and desire. (shrink)

Sometimes it is indeterminate what an agent morally ought do. This generates a Decision Ought Challenge—to give moral guidance to agents in such a scenario. This article is a field guide to the options for a theory of the decision ought for cases of indeterminacy. Three categories of view are evaluated, and the best representative for each is identified.

Joyce (1998) gives an argument for probabilism: the doctrine that rational credences should conform to the axioms of probability. In doing so, he provides a distinctive take on how the normative force of probabilism relates to the injunction to believe what is true. But Joyce presupposes that the truth values of the propositions over which credences are defined are classical. I generalize the core of Joyce’s argument to remove this presupposition. On the same assumptions as Joyce uses, the credences of (...) a rational agent should always be weighted averages of truth value assignments. In the special case where the truth values are classical, the weighted averages of truth value assignments are exactly the probability functions. But in the more general case, probabilistic axioms formulated in terms of classical logic are violated—but we will show that generalized versions of the axioms formulated in terms of non-classical logics are satisfied.

Jeff Paris proves a generalized Dutch Book theorem. If a belief state is not a generalized probability then one faces ‘sure loss’ books of bets. In Williams I showed that Joyce’s accuracy-domination theorem applies to the same set of generalized probabilities. What is the relationship between these two results? This note shows that both results are easy corollaries of the core result that Paris appeals to in proving his dutch book theorem. We see that every point of accuracy-domination defines a (...) dutch book, but we only have a partial converse. (shrink)

Many accounts of structural rationality give a special role to logic. This paper reviews the problem case of clear-eyed logical uncertainty. An account of rational norms on belief that does not give a special role to logic is developed: doxastic probabilism.

John Hawthorne in a recent paper takes issue with Lewisian accounts of counterfactuals, when relevant laws of nature are chancy. I respond to his arguments on behalf of the Lewisian, and conclude that while some can be rebutted, the case against the original Lewisian account is strong. I develop a neo-Lewisian account of what makes for closeness of worlds. I argue that my revised version avoids Hawthorne's challenges. I argue that this is closer to the spirit of Lewis's first (non-chancy) (...) proposal than is Lewis's own suggested modification. (shrink)

The question of the cognitive role of fictionality is this: what is the correct cognitive attitude to take to p, when it is fictional that p? We began by considering one answer to this question, implicit in the work of Kendall Walton, that the correct response to a fictional proposition is to imagine that proposition. However, this approach is silent in cases of fictional incompleteness, where neither p nor its negation are fictional. We argue that that Waltonians should embrace a (...) pluralistic account of the cognitive role of fictional incompleteness: in some cases of fictional incompleteness, we are permitted to resolve the incompleteness during our engagement with the target fiction, and in other cases, we are obliged not to resolve the incompleteness. But though pluralism is accommodated by Walton’s wider account of fictionality, it puts tension on his motivating idea that fictionality stands to the imagination as truth stands to belief. And so we develop a rival conception of the cognitive role of fictionality that is built around a different analogy: on this evidentialist approach, (known) fictionality stands to the imagination as evidence stands to credence.

Recent evidence that young children seem to both understand false belief in one sense, but not in another, has led to two-systems theorizing about mindreading. By analyzing the most detailed two-systems approach in studying social cognition—the theory of mindreading defended by Ian Apperly and Stephen Butterfill—I argue that that even when dutifully constructed, two-systems approaches in social cognition struggle to adequately define the mindreading systems in terms of signature processing limits, an issue that becomes most apparent when investigating mindreading in (...) infancy. I end the article by developing several challenges that face any two-systems account of mindreading. (shrink)

I outline and motivate a way of implementing a closest world theory of indicatives, appealing to Stalnaker's framework of open conversational possibilities. Stalnakerian conversational dynamics helps us resolve two outstanding puzzles for a such a theory of indicative conditionals. The first puzzle -- concerning so-called 'reverse Sobel sequences' -- can be resolved by conversation dynamics in a theoryneutral way: the explanation works as much for Lewisian counterfactuals as for the account of indicatives developed here. Resolving the second puzzle, by contrast, (...) relies on the interplay between the particular theory of indicative conditionals developed here and Stalnakerian dynamics. The upshot is an attractive resolution of the so-called "Gibbard phenomenon" for indicative conditionals. (shrink)

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

There are advantages to thrift over honest toil. If we can make do without numbers we avoid challenging questions over the metaphysics and epistemology of such entities; and we have a good idea, I think, of what a nominalistic metaphysics should look like. But minimizing ontology brings its own problems; for it seems to lead to error theory— saying that large swathes of common-sense and best science are false. Should recherche philosophical arguments really convince us to give all this up? (...) Such Moorean considerations are explicitly part of the motivation for the recent resurgence of structured metaphysics, which allow a minimal (perhaps nominalistic) fundamental ontology, while avoiding error-theory by adopting a permissive stance towards ontology that can be argued to be grounded in the fundamental. This paper evaluates the Moorean arguments, identifying key epistemological assumptions. On the assumption that Moorean arguments can be used to rule out error-theory, I examine deflationary ‘representationalist’ rivals to the structured metaphysics reaction. Quinean paraphrase, fictionalist claims about syntax and semantics are considered and criticized. In the final section, a ‘direct’ deflationary strategy is outlined and the theoretical obligations that it faces are articulated. The position advocated may have us talking a lot like a friend of structured metaphysics—but with a very different conception of what we’re up to. (shrink)

Some argue that theories of universals should incorporate structural universals, in order to allow for the metaphysical possibility of worlds of 'infinite descending complexity' ('onion worlds'). I argue that the possibility of such worlds does not establish the need for structural universals. So long as we admit the metaphysical possibility of emergent universals, there is an attractive alternative description of such cases.

: The current difference in attitude toward germ-line enhancement in humans and nonhumans is unjustified. Society should be more cautious in modifying the genes of nonhumans and more bold in thinking about modifying our own genome. I identify four classes of arguments pertaining to germ-line enhancement: safety arguments, justice arguments, trust arguments, and naturalness arguments. The first three types are compelling, but do not distinguish between human and nonhuman cases. The final class of argument would justify a distinction between human (...) and nonhuman germ-line enhancement; however, this type of argument fails and, therefore, the discrepancy in attitude toward human and nonhuman germ-line enhancement is unjustified.

This essay takes a critical look at aesthetics as the basis for nature preservation, presenting three reasons why we should not rely on aesthetic foundations to justify the environmentalist program. First, a comparison to other kinds of aesthetic value shows that the aesthetic value of nature can provide weak reasons foraction atbest. Second, not everything environmentalists want to protect has positive aesthetic qualities. Attempts have been made to get around this problem by developing a reformist attitude towards natural aesthetics. I (...) argue that these approaches fail. Third, development can be as aesthetically positive as nature. If it is simply beauty we are looking for, why can't the beauty of a wellconstructed dam or a magnificent skyscraper suffice? (shrink)

In some sense, survival seems to be an intrinsic matter. Whether or not you survive some event seems to depend on what goes on with you yourself —what happens in the environment shouldn’t make a difference. Likewise, being a person at a time seems intrinsic. The principle that survival seems intrinsic is one factor which makes personal fission puzzles so awkward. Fission scenarios present cases where if survival is an intrinsic matter, it appears that an individual could survive twice over. (...) But it’s well known that standard notions of “intrinsicality” won’t do to articulate the sense in which survival is intrinsic, since ‘personhood’ appears to be a maximal property. We formulate a sense in which survival and personhood (and perhaps other maximal properties) may be almost intrinsic—a sense that would suffice, for example, to ground fission arguments. It turns out that this notion of almost-intrinsicality allows us to formulate a new version of the problem of the many. (shrink)

This essay explores the thesis that for vague predicates, uncertainty over whether a borderline instance x of red/large/tall/good is to be understood as practical uncertainty over whether to treat x as red/large/tall/good. Expressivist and quasi-realist treatments of vague predicates due to John MacFarlane and Daniel Elstein provide the stalking-horse. It examines the notion of treating/counting a thing as F , and links a central question about our attitudes to vague predications to normative evaluation of plans to treat a thing as (...) F . The essay examines how the account applies to normatively defective or contested terms. The final section raises a puzzle about the mechanics of MacFarlane’s detailed implementation for the case of gradable adjectives. (shrink)

Why should we be means-end rational? Why care whether someone’s mental states exhibit certain formal patterns, like the ones formalized in causal decision theory? This paper establishes a dominance argument for these constraints in a finite setting. If you violate the norms of causal decision theory, then your desires will be aptness dominated. That is, there will be some alternative set of desires that you could have had, which would be more apt (closer to the actual values fixed by your (...) sensibility/ what you intrinsically care about) no matter which world is actual. If we care about having apt desires, then, we should never let ourselves violate these norms of means-end rationality. This argument shares a form with now-standard accuracy arguments for probabilism, opening up a new terrain for that discussion. I show that the foundational assumptions about the shape of accuracy and of aptness required to run the arguments for means-end rationality and for probabilism run closely parallel. I show the argument is robust under different theories of subjective actual value, including nonclassical treatments of indeterminacy in actual value; I show the argument may (but need not!) be generalized to objective theories of value. The upshot is that aptness-domination arguments for decision theories should be added to the philosophical playbook. (shrink)

Abstract In this paper, I examine the plausibility of Embodied Accounts of Social Cognition by finding fault with the most detailed and convincing version of such an account, as articulated by Daniel Hutto ( 2008 ). I argue that this account fails to offer a plausible ontogeny for folk psychological abilities due to its inability to address recent evidence from implicit false belief tasks that suggest a radically different timeline for the development of these abilities.

How are permutation arguments for the inscrutability of reference to be formulated in the context of a Davidsonian truth-theoretic semantics? Davidson takes these arguments to establish that there are no grounds for favouring a reference scheme that assigns London to “Londres”, rather than one that assigns Sydney to that name. We shall see, however, that it is far from clear whether permutation arguments work when set out in the context of the kind of truth-theoretic semantics which Davidson favours. The principle (...) required to make the argument work allows us to resurrect Foster problems against the Davidsonian position. The Foster problems and the permutation inscrutability problems stand or fall together: they are one puzzle, not two. (shrink)

Multiple-choice questions have an undeserved reputation for only being able to test student recall of basic facts. In fact, well-crafted mechanically gradable questions can measure very sophisticated cognitive skills, including those engaged at the highest level of Benjamin Bloom’s taxonomy of outcomes. In this article, I argue that multiple-choice questions should be a part of the diversified assessment portfolio for most philosophy courses. I present three arguments broadly related to fairness. First, multiple-choice questions allow one to consolidate subjective decision making (...) in a way that makes it easier to manage. Second, multiple-choice questions contribute to the diversity of an evaluation portfolio by balancing out problems with writing-based assessments. Third, by increasing the diversity of evaluations, multiple-choice questions increase the inclusiveness of the course. In the course of this argument I provide examples of multiple-choice questions that measure sophisticated learning and advice for how to write good multiple-choice questions. (shrink)

I claim that differences in the importance attached to economic liberty are more important in debates over the use of genetically modified organisms (GMOs) in agriculture than disagreements about the precautionary principle. I will argue this point by considering a case study: the decision by the U.S. Animal and Plant Health Inspection Service (APHIS) to grant nonregulated status to Roundup Ready soy. I will show that the unregulated release of this herbicide-resistant crop would not be acceptable morally unless one places (...) a very high premium on economic liberty. This is true even if one takes a sound science attitude to unknown risks, rather than a precautionary attitude. I concede that it may not have been within APHIS’s legislative mandate to regulate Roundup Ready soy further, but for those of us who do not put a high premium on economic liberty, this only calls for extending regulatory oversight of GMOs.

The impressive variation amongst biological individuals generates many complexities in addressing the simple-sounding question what is a biological individual? A distinction between evolutionary and physiological individuals is useful in thinking about biological individuals, as is attention to the kinds of groups, such as superorganisms and species, that have sometimes been thought of as biological individuals. More fully understanding the conceptual space that biological individuals occupy also involves considering a range of other concepts, such as life, reproduction, and agency. There has (...) been a focus in some recent discussions by both philosophers and biologists on how evolutionary individuals are created and regulated, as well as continuing work on the evolution of individuality.

In this paper, I lend novel support to H. P. Grice’s account of speaker meaning (GASM) by blunting the force of a significant objection. Stephen Schiffer has argued that in order to make GASM sufficient, one must add restrictions that are psychologically impossible to fulfill, thereby making GASM untenable. In what follows, I explain the elements of GASM that require it to invoke these psychologically unrealizable restrictions. I then accept Schiffer’s criticism, but modify its significance to GASM. I argue that (...) the problem that Schiffer notes is not a reason to reject GASM, but a reason to embrace it. GASM shows that meaning is best understood as an absolute concept—an unrealizable ideal limit. Taking some inspiration from contextualist theories of knowledge attribution, I argue that my version of GASM offers a useful contextualist account of meaning attribution. Hence, pragmatic theories of meaning and communication should not wholly exclude GASM from their theorizing, at least not for the reasons that are commonly given. (shrink)

This is the annotated bibliography that accompanied Volume 2 of American Association of Philosophy Teachers Studies in Pedagogy, a special issue on teaching Plato. It includes sections covering teaching several specific dialogues: Republic, Meno, Euthyphro, Apology, Crito and Lysis, as well as sections on "Socrates as Teacher" and general articles on teaching Plato.

In this paper, I outline evidence of Paul Grice’s enduring influence in Psycho-linguistics and the Philosophy of Language. I focus on two particular cases: the role of intentions within developmental psycholinguistics and the notion of what is said within current debates over the notion of semantic content and the semantic-pragmatic boundary. I end the paper with a brief discussion of a possible difficulty facing those who hope to square Grice’s stance on naturalism with this work.

This is the introduction to a special issue of AAPT Studies in Pedagogy on Teaching Plato. I open by noting that the philosophy of education was of central concern to Plato in a way that you don't often see with philosophers. Only Confucius and John Dewey do as much to make education central to everything else they say. I also note that much subsequent philosophy of education merely rediscovers what Plato already knew. After that, I preview the contents of the (...) volume, emphasizing the ways in which contributors ask us to teach Plato platonically. (shrink)

The differences in the portrayal of Baltar between the original Battlestar Galactica and the re-imagined version represent two different conceptions of evil, and can be used to illustrate ideas about the tyrant from Plato and Boethius.

J. Robert Oppenheimer, a leading physicist in the Manhattan Project, recognized that scientific inquiry and discovery could no longer be separated from their effect on political decision-making, social responsibility, and human endeavor in general. He openly addressed issues of common concern and as a scientist accepted the responsibility brought about by nuclear physics and the atom bomb. In this collection of essays and speeches, Oppenheimer discusses the shift in scientific awareness and its impact on education, the question of openness (...) in a society forced to keep secrets, the conflict between individual concerns and public and political necessity, the future of science and its effects on future politics---in short, the common and uncommon sense we find in our modern day reality.

Suppose you’re certain that a claim—say, ‘Frida is tall’—does not have a determinate truth value. What attitude should you take towards it? This is the question of the cognitive role of indeterminacy. This paper presents a puzzle for theories of cognitive role. Many of these theories vindicate a seemingly plausible principle: if you are fully certain that A, you are rationally required to be fully certain that A is determinate. Call this principle ‘Certainty’. We show that Certainty, in combination with (...) some minimal side premises, entails a very implausible claim: whenever you’re certain that it’s indeterminate whether A, it is rationally required that you reject A. This is a surprising result, which requires abandoning at least some intuitive views about indeterminacy and cognitive role. (shrink)

Michael and MacLeod’s paper on theories of reference for intentional concepts addresses neglected connections between theories of reference and Theory of Mind debates. Unfortunately, their paper neither shows the negative effects of descriptivism on theories of reference for intentional concepts nor provides an adequate picture of how the sort of theory they advocate might explain either the reference of intentional concepts or the puzzles of development on which they focus. In this article, I give reasons to think that the prospects (...) are dim for applying causal approaches to the major topics raised by Michael and MacLeod. (shrink)

What Walker describes as the “epistemological” features of narratives are the very elements that open the door for the threat of the discrepancy. What I have tried to show is that even with some blurry boundaries, and some fallibilism, and some occasional indeterminacy, lots of [normals] will be living their lives in an acceptable fashion, telling self-narratives that misdescribe the causes not just of their casual behavior, but even some of their most moral or existentially important features. If this is (...) right, we need to reconsider just what role narratives play in our social lives—what we construct them for, and how we go about revising them and shaping our lives to conform to them. But what seems unlikely is that even having realistic and challenged psycholanalyzed useful, meaningful, fulfilling existential narratives gets us close to the actual sources of our behavior. This tension, though, can be resolved in myriad ways, but not very likely on the reporter model of self-narratives. (shrink)

Chris Kaposy raises an important point about possible interpretations of advances in neuroscience. Specifically, he argues that certain advances may pose a problem for the folk conception of the mind, and he explains that this has crucial implications for our views of what makes a person rational, free, or responsible. In this commentary, I press Kaposy’s position from an eliminativist perspective. Although he may be correct in believing that advances in neuroscience may be difficult to square with our common or (...) folk views, his arguments fall far short of convincing us that these sort of advancements are somehow impossible to adopt, or somehow inconsistent with the possibility of something like epistemic normativity. In fact, I will argue that the most rational course of action may involve adopting radical views about neuroscientific advances. (shrink)
