Mainstream teleosemantics is the view that mental representation should be understood in terms of biological functions, which, in turn, should be understood in terms of selection processes. One of the traditional criticisms of teleosemantics is the problem of novel contents: how can teleosemantics explain our ability to represent properties that are evolutionarily novel? In response, some have argued that by generalizing the notion of a selection process to include phenomena such as operant conditioning, and the neural selection that underlies it, (...) we can resolve this problem. Here, we do four things: we develop this suggestion in a rigorous way through a simple example, we draw on recent neurobiological research to support its empirical plausibility, we defend the move from a host of objections in the literature, and we sketch how the picture can be extended to help us think about more complex “conceptual” representations and not just perceptual ones.

Inquiry into the meaning of logical terms in natural language (‘and’, ‘or’, ‘not’, ‘if’) has generally proceeded along two dimensions. On the one hand, semantic theories aim to predict native speaker intuitions about the natural language sentences involving those logical terms. On the other hand, logical theories explore the formal properties of the translations of those terms into formal languages. Sometimes, these two lines of inquiry appear to be in tension: for instance, our best logical investigation into conditional connectives may (...) show that there is no conditional operator that has all the properties native speaker intuitions suggest if has. Indicative conditionals have famously been the source of one such tension, ever since the triviality proofs of both Lewis (1976) and Gibbard (1981) established conclusions which are in prima facie tension with ordinary judgments about natural language indicative conditionals. In a recent series of papers, Branden Fitelson has strengthened both triviality results (Fitelson 2013, 2015, 2016), revealing a common culprit: a logical schema known as IMPORT-EXPORT. Fitelson’s results focus the tension between the logical results and ordinary judgments, since IMPORT-EXPORT seems to be supported by intuitions about natural language. In this paper, we argue that the intuitions which have been taken to support IMPORT-EXPORT are really evidence for a closely related, but subtly different, principle. We show that the two principles are independent by showing how, given a standard assumption about the conditional operator in the formal language in which IMPORT-EXPORT is stated, many existing theories of indicative conditionals validate one, but not the other. Moreover, we argue that once we clearly distinguish these principles, we can use propositional anaphora to show that IMPORT-EXPORT is in fact not valid for natural language indicative conditionals (given this assumption about the formal conditional operator). This gives us a principled and independently motivated way of rejecting a crucial premise in many triviality results, while still making sense of the speaker intuitions which appeared to motivate that premise. We suggest that this strategy has broad application and an important lesson: in theorizing about the logic of natural language, we must pay careful attention to the translation between the formal languages in which logical results are typically proved, and natural languages which are the subject matter of semantic theory.

Theories of function are conventionally divided up into historical and ahistorical ones. Proponents of ahistorical theories often cite the ahistoricity of their accounts as a major virtue. Here, I argue that none of the mainstream “ahistorical” accounts are actually ahistorical. All of them embed, implicitly or explicitly, an appeal to history. In Boorse’s goal-contribution account, history is latent in the idea of statistical-typicality. In the propensity theory, history is implicit in the idea of a species’ natural habitat. In the causal (...) role theory, history is required for making sense of dysfunction. I elaborate some consequences for the functions debate. (shrink)

There is a certain metaphor that has enjoyed tremendous longevity in the evolution of ageing literature. According to this metaphor, nature has a certain goal or purpose, the perpetuation of the species, or, alternatively, the reproductive success of the individual. In relation to this goal, the individual organism has a function, job, or task, namely, to breed and, in some species, to raise its brood to maturity. On this picture, those who cannot, or can no longer, reproduce are somehow invisible (...) to, or even dispensable to, the evolutionary process. Here, I argue that the metaphor should be discarded, not on the grounds that it is a metaphor, but on the grounds that this particular metaphor distorts our understanding of the evolution of ageing. One reason the metaphor is problematic is that it frames senescence and death as nature’s verdict on the value of older individuals. Instead, we should explore a different metaphor: the lengthy post-reproductive period in humans and some other animals is not an accident of culture, but designed by nature for the purpose of supporting and guiding younger generations. On this alternate picture, different stages of life have their own evolutionary rationales, their distinctive design features, their special mandates. (shrink)

As a first pass, physicalism is the doctrine that there is nothing over and above the physical. Much recent philosophical work has been devoted to spelling out what this means in more rigorous terms and to assessing the case for the view. What follows is a survey of such work. I begin by looking at competing accounts of what is meant by nothing over and above and then turn to how the physical should be understood. Once we are clear on (...) the options for formulating the physicalist thesis, we will look at the leading argument for the view. Along the way, I will suggest avenues for further exploration.

One paradigmatic argument from evil against theism claims that, (1) if God exists, then there is no gratuitous evil. But (2) there is gratuitous evil, so (3) God does not exist. I consider three deontological strategies for resisting this argument. Each strategy restructures existing theodicies which deny (2) so that they instead deny (1). The first two strategies are problematic on their own, but their primary weaknesses vanish when they are combined to form the third strategy, resulting in a promising (...) new approach to the problem of evil.

This essay* takes two notions of autonomy and two notions of explanation and argues that colours occur in explanations that fall under all of them. The claim that colours can be used to explain anything at all may seem to some people an outrage. But their pessimism is unjustified and the orthodox dispositional view which may seem to support it, I shall argue, itself has difficulties. In broad terms, Section 2 shows that there exist good straight scientific laws of colour, (...) constituting what one might call a phenomenal science. Section 3 offers a larger view of what we are doing when we attribute colours to things, a view which makes it a case of holistic explanation, similar in many ways to psychological explanation. Section 2 emphasizes the model of scientific explanation, and Section 3 the holistic model found in rational explanation; but it will emerge that colour explanation in different ways fits both models, as it also does the two principal notions of autonomy that the first section identifies.

I develop a reduction of grounding to essence. My approach is to think about the relation between grounding and essence on the model of a certain conceptof existential dependence. I extend this concept of existential dependence in a coupleof ways and argue that these extensions provide a reduction of grounding to essenceif we use sorted variables that range over facts and take it that for a fact to obtain is forit to exist. I then use the account to resolve various (...) issues surrounding the concept of grounding and its connection with essence; apply the account to paradigm cases andto the impure logic of grounding; and respond to objections.

I argue that not all context dependent expressions are alike. Pure (or ordinary) indexicals behave more or less as Kaplan thought. But quasi indexicals behave in some ways like indexicals and in other ways not like indexicals. A quasi indexical sentence φ allows for cases in which one party utters φ and the other its negation, and neither party’s claim has to be false. In this sense, quasi indexicals are like pure indexicals (think: “I am a doctor”/“I am not a (...) doctor” as uttered by different individuals). In such cases involving a pure indexical sentence, it is not appropriate for the two parties to reject each other’s claims by saying, “No.” However, in such cases involving a quasi indexical sentence, it is appropriate for the par- ties to reject each other’s claims. In this sense, quasi indexicals are not like pure indexicals. Drawing on experimental evidence, I argue that gradable adjectives like “rich” are quasi indexicals in this sense. e existence of quasi indexicals raises trouble for many existing theories of context dependence, including standard contextualist and relativist theories. I propose an alternative semantic and pragmatic theory of quasi indexicals, negotiated contextualism, that combines insights from Kaplan 1989 and Lewis 1979. On my theory, rejection is licensed with quasi indexicals (even when neither of the claims involved has to be false) because the two utterances involve conflicting proposals about how to update the conversational score. I also adduce evidence that conflicting truth value assessments of a single quasi indexical utterance exhibit the same behavior. I argue that negotiated contextualism can account for this puzzling property of quasi indexicals as well. (shrink)

One popular reason for rejecting moral realism is the lack of a plausible epistemology that explains how we come to know moral facts. Recently, a number of philosophers have insisted that it is possible to have moral knowledge in a very straightforward way—by perception. However, there is a significant objection to the possibility of moral perception: it does not seem that we could have a perceptual experience that represents a moral property, but a necessary condition for coming to know that (...) X is F by perception is the ability to have a perceptual experience that represents something as being F . Call this the ‘Representation Objection’ to moral perception. In this paper I argue that the Representation Objection to moral perception fails. Thus I offer a limited defense of moral perception. (shrink)

ABSTRACTRecent debate over the semantics and pragmatics of epistemic modals has focused on intuitions about cross-contextual truth-value assessments. In this paper, we advocate a different approach to evaluating theories of epistemic modals. Our strategy focuses on judgments of the incompatibility of two different epistemic possibility claims, or two different truth value assessments of a single epistemic possibility claim. We subject the predictions of existing theories to empirical scrutiny, and argue that existing contextualist and relativist theories are unable to account for (...) the full pattern of observed judgments. As a way of illustrating the theoretical upshot of these results, we conclude by developing a novel theory of epistemic modals that is able to predict the results. (shrink)

How does Aristotle think about sentences like ‘Every x is y’ in the Prior Analytics? A recently popular answer conceives of these sentences as expressing a mereological relationship between x and y: the sentence is true just in case x is, in some sense, a part of y. I argue that the motivations for this interpretation have so far not been compelling. I provide a new justification for the mereological interpretation. First, I prove a very general algebraic soundness and completeness (...) result that unifies the most important soundness and completeness results to date. Then I argue that this result vindicates the mereological interpretation. In contrast to previous interpretations, this argument shows how Aristotle’s conception of predication in mereological terms can do important logical work. (shrink)

Since the early 1980s, private, for-profit corporations have become increasingly involved in all aspects of scientific research, especially of biomedical research. In this essay, I argue that there are dangerous epistemic consequences of this trend, which should be more thoroughly examined by social epistemologists. In support of this claim, I discuss a recent episode of pharmaceutical research involving the painkiller Vioxx. I argue that the research on Vioxx was epistemically problematic and that the primary cause of these inadequacies was faulty (...) institutional arrangements. More specifically, the research was organized in such a way as to allow short-term commercial interests to compromise epistemic integrity. Thus, the Vioxx case study, in conjunction with numerous case studies developed elsewhere, provides strong reasons for believing that the privatization of the biomedical sciences is epistemically worrisome, and it suggests that the primary response to this situation should be a social, or organizational, one. What kind of organizational response would be most beneficial? I briefly discuss two prominent social epistemological proposals for how scientific research should be organized - namely those of Philip Kitcher and Helen Longino - and I suggest that they are incapable of dealing with the phenomenon of privatization. I then draw upon the Vioxx episode in order to outline an alternative suggestion for reorganizing certain aspects of pharmaceutical research. (shrink)

Social contract theorists often take the ideal contract to be the agreement or bargain individuals would make in some privileged choice situation. Recently, experimental philosophers have explored this kind of decision-making in the lab. One rather robust finding is that the exact circumstances of choice significantly affect the kinds of social arrangements experimental subjects unanimously endorse. Yet prior work has largely ignored the question of which of the many competing descriptions of the original position subjects find most compelling. This paper (...) aims to address this gap, exploring how attractive experimental subjects find various characterizations of these circumstances of choice. We find evidence suggesting that no one choice situation can fulfill the role that social contract theorists have hoped it would play. We also find that, contrary to what some prominent social contract theorists have expected, there is no robust relationship between an individual’s ranking of distributive principles and their ranking of various descriptions of the original position. In conclusion, we discuss the broader implications of these results for political philosophy. (shrink)

ABSTRACTIn this paper, I develop a truthmaker semantics for essence and use the semantics to investigate the explanatory role of essence.

The world is swimming in misinformation. Conflicting messages bombard us every day with news on everything from politics and world events to investments and alternative health. The daily paper, nightly news, websites, and social media each compete for our attention and each often insist on a different version of the facts. Inevitably, we have questions: Who is telling the truth? How would we know? How did we get here? What can we do? Beyond Fake News answers these and other queries. (...) It offers a technological and market-based explanation for how our informational environment became so polluted. It shows how purveyors of news often have incentives to mislead us, and how consumers of information often have incentives to be misled. And it chronicles how, as technology improves and the regulatory burdens drop, our information-scape becomes ever more littered with misinformation. Beyond Fake News argues that even when we really want the truth, our minds are built in such a way so as to be incapable of grasping many facts, and blind spots mar our view of the world. But we can do better, both as individuals and as a society. As individuals, we can improve the accuracy of our understanding of the world by knowing who to trust and recognizing our limitations. And as a society, we can take important steps to reduce the quantity and effects of misinformation. (shrink)

Most a posteriori arguments against the existence of God take the following form: (1) If God exists, the world would not be like this (where 'this' picks out some feature of the world like the existence of evil, etc.) (2) But the world is like this . (3) Therefore, God does not exist. Skeptical theists are theists who are skeptical of our ability to make judgments of the sort expressed by premise (1). According to skeptical theism, if there were a (...) God, it is likely that he would have reasons for acting that are beyond our ken, and thus we are not justified in making all-things-considered judgments about what the world would be like if there were a God. In particular, the fact that we don't see a good reason for X does not justify the conclusion that there is no good reason for X. 1 Thus, skeptical theism purports to undercut most a posteriori arguments against the existence of God. What follows is an account of the nature of skeptical theism, an application of skeptical theism to both the argument from evil and the argument from divine hiddenness, and a review of the cases for and against skeptical theism.

I examine how particular social arrangements and incentive structures encourage the honest reporting of experimental results and minimize fraudulent scientific work. In particular I investigate how epistemic communities can achieve this goal by promoting members to police the community. Using some basic tools from game theory, I explore a simple model in which scientists both conduct research and have the option of investigating the findings of their peers. I find that this system of peer policing can in many cases ensure (...) high levels of honesty. (shrink)

Disjunctive antecedent conditionals —conditionals of the form if A or B, C—sometimes seem to entail both of their simplifications and sometimes seem not to. I argue that this behavior reveals a genuine ambiguity in DACs. Along the way, I discuss a new observation about the role of focal stress in distinguishing the two interpretations of DACs. I propose a new theory, according to which the surface form of a DAC underdetermines its logical form: on one possible logical form, if A (...) or B, C does entail both of its simplifications, while on the other, it does not.

I argue that the problem of normative foundations is insoluble. I discuss how and why the apparent problem arose, particularly within the Frankfurt School. Then, I describe various theories of normative foundations and the criticisms that such theories have faced, such as ethno- and andro-centrism, imperialism, and the failure to fulfill their own aims. I make my main argument by way of an analogy: theories of knowledge have wrestled with the question of whether a “given”’ could act as a certain (...) foundation for knowledge. The conclusion is often that no given can function in that way, because the given, which supposedly does not require justification, is therefore necessarily unable to justify knowledge. For similar reasons, I argue, nothing can function as a normative foundation for a critical social theory, because any such normative foundation would have to both stand in no need of normative justification but also justify normative social criticism. I conclude by suggesting that more recent critical theory that does not focus on normative foundations can be understood as justifying their critique by appeal to what people do actually want, rather than what they should rationally want.

Mengzi believed that tyrannical rulers can be justifiably deposed, and many contemporary scholars see this as evidence that that Mengzi endorsed a right of popular rebellion. I argue that the text of the Mengzi reveals a more mixed view, and does so in two respects. First, it suggests that the people are sometimes permitted to participate in a rebellion but not permitted to decide for themselves when rebellion is warranted. Second, it gives appropriate moral weight not to the people’s judgments (...) about the justifiability of rebelling, but rather to certain affections and behaviors that closely track their life satisfaction. I contend that in both respects the permissions Mengzi grants the people fall short of a proper right of rebellion. I conclude that the more historical account of Mengzi’s “just revolt theory” suggests an intriguing division of justificatory labor, and note some of the advantages of this account. (shrink)

Rule A: if it's metaphysically necessary that p, we may validly infer that no one is even partly morally responsible for the fact that p. Our principal aim in this article is to highlight the importance of this rule and to respond to two recent challenges to it. We argue that rule A is more important to contemporary theories of moral responsibility than has previously been recognized. We then consider two recent challenges to the rule and argue that neither challenge (...) successfully undermines the rule's initial appeal. (shrink)

While many recognise that rigid historical and compositional goals are inadequate in a world where climate and other global systems are undergoing unprecedented changes, others contend that promoting ecosystem services and functions encourages practices that can ultimately lower the bar of ecological management. These worries are foregrounded in discussions about 'novel ecosystems' (NEs), where some researchers and conservationists claim that NEs provide a license to trash nature as long as certain ecosystem services are provided. This criticism arises from what we (...) call the 'anything goes problem' created by the release of historical conditions. After explaining the notion of NEs, we identify numerous substantive motivations for worrying about the 'anything goes problem' and then go on to show that the problem can be solved by correcting two mistaken assumptions. In short, we argue that the problem is a product of adopting an overly sparse functional perspective that assumes an unrealistically high degree of convergence in the trajectories of natural processes; our analysis illuminates why such assumptions are unwarranted. Further, we argue that adopting an appropriate ethical framework is essential to overcoming the 'anything goes problem', and suggest that a certain virtue-ethics conception of ecological management provides useful resources for framing and resolving the problem.

Recently, philosophers have drawn on tools from game theory to explore behavior in Hobbes’ state of nature. I take a similar approach and argue the Lockean state of nature is best conceived of as a conflictual coordination game. I also discuss Nozick’s famous claim regarding the emergence of the state and argue the path to the minimal state is blocked by a hitherto unnoticed free-rider problem. Finally, I argue that on my representation of the Lockean state of nature both widespread (...) conflict and lasting peace are possible. This, I contend, is in line with one popular interpretation of Locke. (shrink)

Nietzsche’s presentation of the eternal recurrence in Gay Science 341 is often viewed as a practical thought experiment meant to radically transform us. But exactly why and how we are supposed to be transformed is not clear. I contend that addressing these issues requires taking a close look at the psychological setting of the passage. The eternal recurrence is presented in our “loneliest loneliness.” I argue that facing the eternal recurrence from a state of profound loneliness both motivates self-transformation and (...) contributes toward helping us succeed at that project.

The revival of virtue ethics over the last thirty‐five years has produced a bewildering diversity of theories, which on the face of it seem united only by their opposition to various features of more familiar Kantian and Utilitarian ethical theories. In this paper I present a systematic account of the main positive features of virtue ethics, by articulating the common ground shared by its different varieties. I do so not to offer a fresh defence of virtue ethics, but rather to (...) provide a conceptual map that locates its main claims and arguments in relation to those of rival theories, and identifies its distinctive contribution to contemporary ethics. I set out six specific claims which are made by all forms of virtue ethics, and I explain how these claims distinguish the theory from recent character‐based forms of Kantian ethics and Utilitarianism. I then use this framework to briefly survey two main strands of virtue ethics which have been developed in the literature.1. (shrink)

ABSTRACTSome proponents of the evolutionary debunking argument against moral realism believe that replies that assume substantive moral claims beg the question. In this paper, I give a new account of what's wrong with such replies. On this account, many realists beg the question when they rely on substantive moral claims in their replies to the argument, but naturalists do not. While this account generalizes to some other domains, it allows perceptual and inductive realism to remain undebunked.

One objection to the thesis that multilocation is possible claims that, when combined with a preference for parsimonious theories, it leads to the absurd result that we ought to believe the material universe is composed of just one simple particle. I argue that this objection fails.

Reformed epistemology and cognitive science have remarkably converged on belief in God. Reformed epistemology holds that belief in God is basic—that is, belief in God is a natural, non-inferential belief that is immediately produced by a cognitive faculty. Cognitive science of religion also holds that belief in gods is (often) non-reflectively and instinctively produced—that is, non-inferentially and automatically produced by a cognitive faculty or system. But there are differences. In this paper, we will show some remarkable points of convergence, and (...) a few points of divergence, between Reformed epistemology and the cognitive science of religion. (shrink)

Byerly has proposed a novel solution to the gap problem for cosmological arguments. I contend that his strategy can be used to strengthen a wide range of other theistic arguments as well, and also to stitch them together into a cumulative case for theism. I illustrate these points by applying Byerly’s idea about cosmological arguments to teleological arguments.

Iris Murdoch was a notable philosopher before she was a notable novelist and her work was brave, brilliant, and independent. She made her name first for her challenges to Gilbert Ryle and behaviourism, and later for her book on Sartre, but she had the greatest impact with her work in moral philosophy—and especially her book The Sovereignty of Good. She turned expectantly from British linguistic philosophy to continental existentialism, but was dissatisfied there too; she devised a philosophy and a style (...) of philosophy that were distinctively her own. Murdoch aimed to draw out the implications, for metaphysics and the conception of the world, of rejecting the standard dichotomy of language into the 'descriptive' and the 'emotive'. She aimed, in Wittgensteinian spirit, to describe the phenomena of moral thinking more accurately than the 'linguistic behaviourists' like R. M. Hare. This 'empiricist' task could be acheived, Murdoch thought, only with help from the idealist tradition of Kant, Hegel, and Bradley. And she combined with this a moral psychology, or theory of motivation, that went back to Plato, but was influenced by Freud and Simone Weil. Murdoch's impact can be seen in the moral philosophy of John McDowell and, in different ways, in Richard Rorty and Charles Taylor, as well as in the recent movements under the headings of moral realism, particularism, moral perception, and virtue theory. This volume brings together essays by critics and admirers of Murdoch's work, and includes a longer Introduction on Murdoch's career, reception, and achievement. It also contains a previously unpublished chapter from the book on Heidegger that Murdoch had been working on shortly before her death, and a Memoir by her husband John Bayley. It gives not only an introduction to Murdoch's important philosophical life and work, but also a picture of British philosophy in one of its heydays and at an important moment of transition.Readership: Students and scholars of philosophy and literature.

A plausible constraint on normative reasons to act is that it must make sense to use them as premises in deliberation. I argue that a central sort of deliberation – what Bratman calls partial planning – is question-directed: it is over, and aims to resolve, deliberative questions. Whether it makes sense to use some consideration as a premise in deliberation in a case of partial planning can vary with the deliberative question at issue. I argue that the best explanation for (...) this is that reasons are contrastive or relativized to deliberative questions. (shrink)

In this journal, Schulte develops a novel solution to the problem of distal content: by virtue of what is a mental representation about a distal object rather than a more proximal cause of that representation? Schulte maintains that in order for a representation to have a distal content, it must be produced by a constancy mechanism, along with two other conditions. I raise three objections to his solution. First, a core component of Schulte's solution is just a restrictive version of (...) Dretske's solution, but Schulte gives no argument for his restriction. Second, his proposed solution to a disjunction problem is ad hoc. Finally, his ‘far-out’ version of the distality problem is not a version of the distality problem at all. I conclude that Dretske's solution is preferable to Schulte's. (shrink)

It is widely held that the classic reassembly model of resurrection faces intractable problems. What happens to someone if God assembles two individuals at the resurrection which are equally good candidates for being the original person? If two or more people, such as a cannibal and the cannibal’s victim, were composed of the same particles at their respective deaths, can they both be resurrected? If they can, who gets the shared particles? And would an attempt to reassemble a long-gone individual (...) result in a genuine resurrection, or merely an intrinsic duplicate of the original person? In this paper, I argue that the first of these problems has, in effect, been solved by defenders of a rival view; I propose a novel solution to the second problem; and I show that the third can be solved by upgrading the naïve reassembly model to a novel variety of reassembly model.

‘Epistocracy’ is the name of a type of political power structure in which the power is held by the knowledgable—for example, by restricting the right to vote to those who can demonstrate sufficient knowledge. Though Plato and Mill defended epistocratic views, it has found few contemporary advocates. In a recent book, however, Jason Brennan argues that epistocratic power structures are capable of outperforming democratic ones. His argument is two-pronged: first, he argues that democratic procedures with universal suffrage allow poorly-informed voters (...) to pollute the electorate, and that doing so has negative policy-related consequences that are easily avoidable. Second, he argues that voting does not possess any non-intrinsic value, and so restricting suffrage to the educated does not result in a loss of status or standing for less well-educated persons in any meaningful way. I argue that epistocratic techniques are impossible to implement fairly, and represent an ineffective solution for the problems they are designed to solve. On these bases, I recommend rejecting it.

The first use of the term "information" to describe the content of nervous impulse occurs 20 years prior to Shannon`s (1948) work, in Edgar Adrian`s The Basis of Sensation (1928). Although, at least throughout the 1920s and early 30s, the term "information" does not appear in Adrian`s scientific writings to describe the content of nervous impulse, the notion that the structure of nervous impulse constitutes a type of message subject to certain constraints plays an important role in all of his (...) writings throughout the period. The appearance of the concept of information in Adrian`s work raises at least two important questions: (i) what were the relevant factors that motivated Adrian`s use of the concept of information? (ii) What concept of information does Adrian appeal to, and how can it be situated in relation to contemporary philosophical accounts of the notion of information in biology? The first question involves an account of the application of communications technology in neurobiology as well as the historical and scientific background of Adrian`s major scientific achievement, which was the recording of the action potential of a single sensory neuron. The response to the second question involves an explication of Adrian`s concept of information and an evaluation of how it may be situated in relation to more contemporary philosophical explications of a semantic concept of information. I suggest that Adrian`s concept of information places limitations on the sorts of systems that are referred to as information carriers by causal and functional accounts of information. (shrink)

At the beginning of the twentieth century, the French philosopher of science Edmond Goblot wrote three prescient papers on function and teleology. He advanced the remarkable thesis that functions are, as a matter of conceptual analysis, selected effects. He also argued that “selection” must be understood broadly to include both evolutionary natural selection and intelligent design. Here, I do three things. First, I give an overview of Goblot’s thought. Second, I identify his core thesis about function. Third, I argue that, (...) despite its ingenuity, Goblot’s expansive construal of function cannot be right. Still, Goblot deserves long-overdue credit for his work. (shrink)

Philosophers and social scientists have recently turned to game theory and agent-based models to better understand social contract formation. The stag hunt game is an idealization of social contract formation. Using the stag hunt game, we attempt to determine what, if any, barrier diversity is to the formation of an efficient social contract. We uncover a deep connection between tolerance, diversity, and the social contract. We investigate a simple model in which individuals possess salient traits and behave cooperatively when the (...) difference between their trait and the trait of their counterpart is less than their ‘tolerance level’. If traits are fixed and correspond to permanent or semipermanent features of the individual, such as religion or race, social contract formation is a remote possibility. If traits are malleable, social contract formation is possible but comes at the steep cost of diversity and tolerance, that is, individuals are unwilling to cooperate with those much different from themselves. Yet homogeneity and intolerance are not a long-term feature of the population. Over time mutations allow for increasingly tolerant agents to prosper, thereby ushering in trait diversity. In the end, all reap the benefits of cooperation. (shrink)

John Martin Fischer has argued that Molinism does not constitute a response to the argument that divine foreknowledge is incompatible with human freedom. I argue that T. Ryan Byerly’s recent work on the mechanics of foreknowledge sheds light on this issue. It shows that Fischer’s claim is ambiguous, and that it may turn out to be false on at least one reading, but only if the Molinist can explain how God knows true counterfactuals of freedom.

This chapter discusses color blindness and how it can be considered a guide and test for theories of normal vision. There are a multitude of stories to be told about the physiology of the receptor pigments of the eye and the genes that code for them, about the various kinds of cells in the retina and elsewhere in the visual system, and about color processing in the brain. It is a topic on which psychologists, physicists, biologists, and neurophysiologists have reason (...) to be proud and glad of the convergence of interests and views. Color blindness might, at first, seem just a peripheral abnormality, but it has often been both a guide to the nature of normal color vision and a test application for theories of it. It has the potential to provide cases where the various components of a complex process that are either hard or impossible to separate artificially are found already separated in nature. (shrink)

The problem of Kant’s Neglected Alternative is that while his Aesthetic provides an argument that space and time are empirically real – in applying to all appearances – its argument seems to fall short of the conclusion that space and time are transcendentally ideal, in not applying to any things in themselves. By considering an overlooked passage in which Kant explains why his Transcendental Deduction is ‘unavoidably necessary’, I argue that it is not solely in his Aesthetic but more so (...) in his Deduction where he intends to provide his argument for the transcendental ideality of space and time. His Deduction shows that space and time do not have a valid application to any things in themselves by arguing that the categories do have a valid application to everything in space and time, but that the categories do not have a valid application to any things in themselves.

The present study sought to determine whether Barrett's counterintuitiveness coding and quantifying scheme could be applied to cultural materials with sufficient intercoder reliability, provide evidence concerning just how counterintuitive is too counterintuitive for a concept to be a recurrent cultural idea, and test whether counterintuitive intentional agent concepts are more common in folktales than other classes of counterintuitive concepts. Seventy-three folktales from around the world were sampled from larger collections. Using Barrett's CI-Scheme, two independent coders identified 116 counterintuitive objects and (...) scored them for degree of counterintuitiveness with very high inter-rater concordance. Of folktales, 79% had one or two counterintuitive objects. Of the counterintuitive objects 93% had a counterintuitiveness score of only one. Of counterintuitive objects, 98% were agents. Results suggest the CI-Scheme may have utility for analyzing cultural materials, that the cognitive optimum for cultural transmission falls around one counterintuitive feature, and that counterintuitive agents are more common than other types of counterintuitive objects in folktales.

Drawing on contemporary agency theory and the phenomenological-existential tradition, this paper uses Mr. Stevens, the narrator-butler of Kazuo Ishiguro’s The Remains of the Day, to examine the interplay and potential tensions between different aspects (and thus different standards) of human agency. Highlighting the problem of mission creep described by John Martin Fischer, in which a notion expands beyond the original purpose, I use Stevens’s thoughts on dignity to outline three different ways actions can (or can fail to) trace back to (...) agents—autonomy as self-control, authenticity as sincerity, and authenticity as ownership. I then propose that the way Stevens embraces and acts consistently within his subservient professional role (autonomy as self-control) weakens his ability to take responsibility for his life in the sense required by authenticity as ownership. Because the self-responsibility of authenticity requires normative flexibility (the ability to revise and reshape one’s commitments and values), when normatively inflexible agents act in self-controlled ways according to their roles or welfare standards, they may limit their ability to take responsibility for their lives. In addition to illuminating debates about whether robust human agency is compatible with subservience, the normative flexibility involved in authenticity has implications for human agency more broadly.

Where are we to look for the unique hues? Out in the world? In the eye? In more central processing? 1. There are difficulties looking for the structure of the unique hues in simple combinations of cone-response functions like ( L − M ) and ( S − ( L + M )): such functions may fit pretty well the early physiological processing, but they don’t correspond to the structure of unique hues. It may seem more promising to look to, (...) e.g., Hurvich & Jameson’s ‘chromatic response functions’; but these report on psychophysical behaviour, not on underlying physiology. So ‘opponent processing’ isn’t any particular help on the unique hues—and even physiology in general seems not to have come up with any good correlate or explanation. 2. Wright ( Review of Philosophy and Psychology 2: 1–17, 2011 ) looks in a different place: to (a) magnitude of total visual response that a stimulus light provokes, the maxima and minima of which, he thinks, give us the boundaries of the main hue categories (Wright connects these with Thornton’s ‘prime’ and ‘antiprime’ colours in an illuminant: Journal of the Optical Society of America 61 ( 1971 ): 1155–1163); and (b) the ratio of chromatic to achromatic response, the maxima and minima of which, he suggests, give us the focal points of the unique hues. The suggestions are extremely interesting; but the desired correspondences have some counterexamples; and where they hold, one could wonder how much they depend upon the particular choice of functions to measure (a) and (b); and one could hope for more of an explanatory linkage between the sets of items in question. 3. Could the unique hues come from, so to speak, the external world? White and black can easily be defined as particular kinds of reflectance. What of the standard four unique hues? Variation in kinds of sunlight and skylight coincides well with variation along a line from unique yellow to unique blue (cf. Shepard 1992 , Mollon 2006 ). If we wanted something to calibrate our standards for unique yellow and blue as the lens of the eye changes with age, and despite interpersonal cone differences, this would be a good basis—and there are several ways this can be extended to surface colours. But is there any essential connection between these things: is there any rationale why the light of the sun and the sky should be counted as unique hued ? An answer may be: because in our environment, these illuminants are as close to white (or the natural illuminant colour) as you can get—to see things tinged with sunlight or skylight should be to see them minimally tinged with any alien colour. Whereas other hues in an illuminant would be treated as tinging with a more alien colour the thing seen. (shrink)
