Charles Travis presents a series of essays on philosophy of perception, inspired by the insights of Gottlob Frege. He engages with a range of contemporary thinkers, and explores key issues including how perception can make the world bear on what we do or think, and what sorts of capacities we draw on in representing something as (being) something.

In this book, Travis DeCook explores the theological and political innovations found in early modern accounts of the Bible's origins. In the charged climate produced by the Reformation and humanist historicism, writers grappled with the tension between the Bible's divine and human aspects, and they produced innovative narratives regarding the agencies and processes through which the Bible came into existence and was transmitted. DeCook investigates how these accounts of Scripture's production were taken up beyond the expected boundaries of biblical (...) study, and were redeployed as the theological basis for wide-reaching arguments about the proper ordering of human life. DeCook provides a new, critical perspective on ideas regarding secularity, secularization, and modernity, challenging the dominant narratives regarding the Bible's role in these processes. He shows how these engagements with the Bible's origins prompt a rethinking of formulations of secularity and secularization in our own time. (shrink)

What is insensitive semantics (also semantic minimalism, henceforth SM)? That will need to emerge, if at all, from the authors’ (henceforth C&L) objections to what they see as their opponents. They signal two main opponents: moderate contextualists (henceforth MCs); and radical contextualists (henceforth RCs). I am signaled as a main RC. I will thus henceforth represent that position in propria persona. In most general lines the story is this: MC collapses into RC; RC is incoherent, or inconsistent, on various counts; (...) SM is thus the only game in town. As to all of that, we shall see. (shrink)

In “Save the Children!” Artúrs Logins responds to my argument that, in certain cases, it is morally permissible to not prevent something bad from happening, even when one can do so without sacrificing something of comparable moral importance. Logins’ responses are thought-provoking, though I will argue that his critiques miss their mark. I rebut each of the responses offered by Logins. However, much of my focus will be on one of his criticisms which rests on an unfortunately common misunderstanding of (...) Singer’s argument in “Famine, Affluence, and Morality.” My response, then, is important not only because it salvages my positive argument, but also because it identifies, and corrects, this misunderstanding.

Many of us believe that we can and do have individual obligations to refrain from contributing to massive collective harms – say, from producing luxury greenhouse gas (GHG) emissions; however, our individual actions are so small as to be practically meaningless. Can we then, justify the intuition that we ought to refrain? In this paper, we argue that this debate may have been mis-framed. Rather than investigating whether or not we have obligations to refrain from contributing to collective action, perhaps (...) we should ask whether we have reason to do so. However, this framing brings challenges of its own, and so we close by asking what problems are generated if we focus on these questions of ‘contributory ethics’. (shrink)

The ontology of Bohmian mechanics includes both the universal wave function and particles. Proposals for understanding the physical significance of the wave function in this theory have included the idea of regarding it as a physically-real field in its 3N-dimensional space, as well as the idea of regarding it as a law of nature. Here we introduce and explore a third possibility in which the configuration space wave function is simply eliminated—replaced by a set of single-particle pilot-wave fields living in (...) ordinary physical space. Such a re-formulation of the Bohmian pilot-wave theory can exactly reproduce the statistical predictions of ordinary quantum theory. But this comes at the rather high ontological price of introducing an infinite network of interacting potential fields which influence the particles’ motion through the pilot-wave fields. We thus introduce an alternative approach which aims at achieving empirical adequacy with a more modest ontological complexity, and provide some preliminary evidence for optimism regarding the program of trying to replace the configuration space wave function with a set of fields in ordinary physical space.

This paper attempts to show that contextualism cannot adequately handle all versions of ‘The Lottery Paradox.” Although the application of contextualist rules is meant to vindicate the intuitive distinction between cases of knowledge and non-knowledge, it fails to do so when applied to certain versions of “The Lottery Paradox.” In making my argument, I first briefly explain why this issue should be of central importance for contextualism. I then review Lewis’ contextualism before offering my argument that the lottery paradox persists (...) on all contextualist accounts. Although I argue that the contextualist does not fare well, hope nevertheless remains. For, on Lewis’ behalf, I offer what I take to be the best solution for the contextualist and argue that once this solution is adopted, contextualism will be in a better position to handle the lottery paradox than any other substantive epistemological theory.

There is a view abroad on which perceptual experience has representational content in this sense: in it something is represented to the perceiver as so. On the view, a perceptual experience has a face value at which it may be taken, or which may be rejected. This paper argues that that view is mistaken: there is nothing in perceptual experience which makes it so that in it anything is represented as so. In that sense, the senses are silent, or, in (...) Austin's term, dumb. Perceptual experience is not as such either veridical or delusive. It may mislead, but it does not take representation to accomplish that. (shrink)

Mark Schroeder has, rather famously, defended a powerful Humean Theory of Reasons. In doing so, he abandons what many take to be the default Humean view of weighting reasons—namely, proportionalism. On Schroeder’s view, the pressure that Humeans feel to adopt proportionalism is illusory, and proportionalism is unable to make sense of the fact that the weight of reasons is a normative matter. He thus offers his own ‘Recursive View’, which directly explains how it is that the weight of reasons is (...) a normative matter. In this paper, I argue against Schroeder that a Humean ought to be a proportionalist. On my view, proportionalism is clearly an intuitive theory of weighting for a Humean, so we should resist it only if Schroeder can demonstrate either that there is a serious problem with the view, or that there is a better alternative. I then further argue that Schroeder fails to deliver on either condition. As a result, I conclude that there are good intuitive reasons for a Humean to be a proportionalist, and no good reason not to be. (shrink)

Complex work in teams requires coordination across team members and their technology as well as the ability to change and adapt over time to achieve effective performance. To support such complex interactions, recent efforts have worked toward the design of adaptive human-autonomy teaming systems that can provide feedback in or near real time to achieve the desired individual or team results. However, while significant advancements have been made to better model and understand the dynamics of team interaction and its relationship (...) with task performance, appropriate measures of team coordination and computational methods to detect changes in coordination have not yet been widely investigated. Having the capacity to measure coordination in real time is quite promising as it provides the opportunity to provide adaptive feedback that may influence and regulate teams’ coordination patterns and, ultimately, drive effective team performance. A critical requirement to reach this potential is having the theoretical and empirical foundation from which to do so. Therefore, the first goal of the paper is to review approaches to coordination dynamics, identify current research gaps, and draw insights from other areas, such as social interaction, relationship science, and psychotherapy. The second goal is to collate extant work on feedback and advance ideas for adaptive feedback systems that have potential to influence coordination in a way that can enhance the effectiveness of team interactions. In addressing these two goals, this work lays the foundation as well as plans for the future of human-autonomy teams that augment team interactions using coordination-based measures. (shrink)

I formulate a compatibilism that is distinctively responsive to skeptical worries about the justification of punishment and other moral responsibility practices. I begin with an evolutionary story explaining why backward-looking reactive attitudes are “given” in human society. Cooperative society plausibly could not be sustained without such practices. The necessary accountability practices have complex internal standards. These internal standards may fully ground the appropriateness of reactive attitudes. Following a recent analogy, we can similarly hold that there are no external standards for (...) what is funny; the norms of comedy are complex, but funny is funny. However, this is compatible with moral reasons to change the practices themselves, and therefore change what is fitting within them: in the first instance, a moralistic “that's not funny” is ill-fitting, but “that shouldn't be funny” can be apt. The analogous reformist position prescribes practices constituting the minimal responsibility norms necessary for cooperative society. (shrink)

Multiple theories of problem-solving hypothesize that there are distinct qualitative phases exhibited during effective problem-solving. However, limited research has attempted to identify when transitions between phases occur. We integrate theory on collaborative problem-solving with dynamical systems theory suggesting that when a system is undergoing a phase transition it should exhibit a peak in entropy and that entropy levels should also relate to team performance. Communications from 40 teams that collaborated on a complex problem were coded for occurrence of problem-solving processes. (...) We applied a sliding window entropy technique to each team's communications and specified criteria for identifying data points that qualify as peaks and determining which peaks were robust. We used multilevel modeling, and provide a qualitative example, to evaluate whether phases exhibit distinct distributions of communication processes. We also tested whether there was a relationship between entropy values at transition points and CPS performance. We found that a proportion of entropy peaks was robust and that the relative occurrence of communication codes varied significantly across phases. Peaks in entropy thus corresponded to qualitative shifts in teams’ CPS communications, providing empirical evidence that teams exhibit phase transitions during CPS. Also, lower average levels of entropy at the phase transition points predicted better CPS performance. We specify future directions to improve understanding of phase transitions during CPS, and collaborative cognition, more broadly. (shrink)

I argue that two components of Thomistic philosophy of nature (specifically, hylomorphism combined with a relational ontology of space) entail a core claim of big-bang cosmology. I then consider some implications of this fact for natural theology.

A subarea of the debate over the nature of evolutionary theory addresses what the nature of the explanations yielded by evolutionary theory are. The statisticalist line is that the general principles of evolutionary theory are not only amenable to a mathematical interpretation but that they need not invoke causes to furnish explanations. Causalists object that construction of these general principles involves crucial causal assumptions. A recent view claims that some biological explanations are statistically autonomous explanations (SAEs) whereby phenomena are accounted (...) for statistically and which prescind from micro-causal details. I raise three major problems for this account and then advance a view which unifies SAEs as mathematical explanations: the MSAE view. The MSAE view not only resolves the issues bedeviling the original SAE account but serves to importantly broaden the class of non-causal explanations in population biology. (shrink)

“Jury Nullification, Verdictal Asymmetry, and the Ultimate Logic of Anarchy” is a critical examination and analysis of the ‘anarchy objection’ to jury nullification, a common argument against informing juries of their nullification power. The anarchy objection posits that jury nullification leads to inconsistent verdicts (verdictal asymmetry) and, as a result, social anarchy and chaos. Through careful analysis, I argue that the anarchy objection is predicated on two flawed premises: first, that jury nullification promotes verdictal asymmetry, and second, that such asymmetry (...) leads to anarchy. Such commitments are, I argue, empirically unsupported and conceptually misguided. Verdictal asymmetry is an intrinsic feature of the common law system, present at nearly every adjudicative stages, and not uniquely linked to jury nullification; yet we certainly do not live in an environment of jural/social anarchy. Finally, I discuss how the principle of treating like cases alike is primarily a procedural constraint, not a mandate for verdictal symmetry. By dismantling the anarchy objection, I aim to contribute to a deeper understanding of the jurisprudence surrounding the jury nullification debate and its role within the legal system. (shrink)

This book continues to be one of the more widely read books in psychology. Skinner's magnum opus is one of a handful of books that changed the face of modern psychology. The Behavior of Organisms provided the first example of the use of the operant method to measure behavioral effects of drugs and led to the development of teaching machines, programmed instruction and community treatment programs for juvenile delinquents. The functional unit Skinner defined in his doctoral dissertation and explicated in (...) The Behavior of Organisms remains the foundation of modern behavior analysis. The operant was defined as a class of behavior bearing characteristic probability relations with environmental events previously occurring after instances of members of that class. The Behavior of Organisms is a remarkably mature book written by the author when he was in his early 30s. The regularities and principles explicated in The Behavior of Organisms stand largely intact after half a century, and the analytic strategy has been highly effective. (shrink)

The debate over the explanatory nature of cognitive models has been waged mostly between two factions: the mechanists and the dynamical systems theorists. The former hold that cognitive models are explanatory only if they satisfy a set of mapping criteria, particularly the 3M/3m* requirement. The latter have argued, pace the mechanists, that some cognitive models are both dynamical and constitute covering-law explanations. In this paper, I provide a minimal model interpretation of dynamical cognitive models, arguing that this both provides needed (...) clarity to the mechanist versus dynamicist divide in cognitive science and also paves the way towards further insights about scientific explanation generally.

Charles Travis presents a series of essays in which he has developed his distinctive view of the relation of thought to language. The key idea is "occasion-sensitivity": what it is for words to express a given concept is for them to be apt for contributing to any of many different conditions of correctness (notably truth conditions). Since words mean what they do by expressing a given concept, it follows that meaning does not determine truth conditions. This view ties thoughts (...) less tightly to the linguistic forms which express them than traditional views of the matter, and in two directions: a given linguistic form, meaning fixed, may express an indefinite variety of thoughts; one thought can be expressed in an indefinite number of syntactically and semantically distinct ways. Travis highlights the importance of this view for linguistic theory, and shows how it gives new form to a variety of traditional philosophical problems. (shrink)

There are too many people on the planet. This isn’t a popular thing to say, but it’s becoming more and more obvious that it’s true, and that we need to do something to address it. Even in our radically unjust world, where billions of people do not have adequate access to food, water, energy, and other resources, we’re still living unsustainably—overcharging our ecological credit card and torching the climate. But discussing the link between these environmental problems and the population is (...) uncomfortable, because many people believe that procreation is an essentially private act that is morally and politically off-limits. In her new book, One Child, Sarah Conly argues that this belief is false: If... (shrink)

Multidisciplinary critiques of the notion of rape as an evolutionary adaptation.

Recent work on Mary Shepherd has largely focused on her metaphysics, especially as a response to Berkeley and Hume. However, relatively little attention has thus far been paid to the epistemological aspects of Shepherd’s program. What little attention Shepherd’s epistemology has received has tended to cast her as providing an unsatisfactory response to the skeptical challenge issued by Hume. For example, Walter Ott and Jeremy Fantl have each suggested that Shepherd cannot avoid Hume’s inductive skepticism even if she is granted (...) her metaphysics. In this paper, I examine Shepherd’s epistemology and argue that her response to Hume is more successful than the current literature suggests. In particular, I argue that, if Shepherd is granted her metaphysics, she can answer Hume’s demand for a rational justification of ordinary inductive inferences via a deductively justified uniformity principle and an appeal to parsimony.

The question of how to frame agential preferences in economics finds one caught between Scylla and Charybdis. If preferences are framed in as minimal and deflationary a manner as revealed preference theory recommends, the theory falls prey to objections about its predictiveness and explanatory power. Alternatively, if too many cognitive and causal intricacies are incorporated into the preference concept, revealed preference models will violate pragmatic norms of model construction, surrendering model simplicity and generality. This paper charts a middle course, arguing (...) that the path to salvation lies through an understanding of revealed preference models as program explanations. (shrink)

I consider how complex logical operations might self-assemble in a signalling-game context via composition of simpler underlying dispositions. On the one hand, agents may take advantage of pre-evolved dispositions; on the other hand, they may co-evolve dispositions as they simultaneously learn to combine them to display more complex behaviour. In either case, the evolution of complex logical operations can be more efficient than evolving such capacities from scratch. Showing how complex phenomena like these might evolve provides an additional path to (...) the possibility of evolving more or less rich notions of compositionality. This helps provide another facet of the evolutionary story of how sufficiently rich, human-level cognitive or linguistic capacities may arise from simpler precursors. 1Signalling and Self-assembly2Simple Unary Logic Games3Composing Unary Functions for Binary Inputs 3.1Utilizing pre-evolved dispositions3.2Co-evolving logical dispositions3.3Learning appropriate outputs3.4Taking account of the full state-space of unary games3.5Role-free composition4Discussion 4.1Efficacy and efficiency of learning complex dispositions4.2Other binary operations4.3To infinity and beyond5Conclusion.

Neonatal intensive care units represent simultaneously one of the great success stories of modern medicine, and one of its most controversial developments. One particularly controversial issue is the resuscitation of extremely preterm infants. Physicians in the United States generally accept that they are required to resuscitate infants born as early as 25 weeks and that it is permissible to resuscitate as early as 22 weeks. In this article, I question the moral pressure to resuscitate by criticizing the idea that resuscitation (...) in this context “saves” a human life. Our radical medical advancements have allowed us to intervene in the life of a human before it makes sense to say that such an intervention “saves” someone; rather, what the physician does in resuscitating and treating an extremely preterm infant is to take over creating it. This matters, I argue, because “rescues” are much more morally urgent than “creations.”. (shrink)

In support of logical nihilism, according to which there are no logical laws, Gillian Russell offers purported counterexamples to two laws of logic. Russell’s examples rely on cleverly constructed predicates not found in ordinary English. I show that similar apparent counterexamples to the same logical laws can be constructed without exotic predicates but using only what ordinary language provides. We correctly analyze such arguments so that they do not actually constitute counterexamples to any logic laws. I claim that we can (...) and should do the same for Russell’s arguments. (shrink)

What accounts for the linkage of seemingly diverse and inherently separable fundamental properties, such that they are regarded as properties of a single thing? Multiple answers to this question have been put forward in both the historical and current literature, especially from competing substance ontologies and competing theories concerning the metaphysics of natural kinds. Here I lay out and critically assess two ways in which dispositionalism might contribute to the discussion.

This book provides a novel interpretation of the ideas about language in Ludwig Wittgenstein's Philosophical Investigations. Travis places the "private language argument" in the context of wider themes in the Investigations, and thereby develops a picture of what it is for words to bear the meaning they do. He elaborates two versions of a private language argument, and shows the consequences of these for current trends in the philosophical theory of meaning.

It is an underappreciated fact within the philosophical literature on laws of nature that many scientific laws require the aid of a supporting cast of additional modelling ingredients (such as boundary conditions, material parameters, interfacial stipulations, rigidity constraints, and so on) in order to perform their traditional role in scientific inquiry. In this paper, I suggest that this underappreciated fact spells trouble for some recent reformulations of David Lewis's Best Systems Account (BSA) of laws of nature. Under the auspices of (...) 'pragmatic Humeanism,' several philosophers have recently argued that the criteria of strength and simplicity that lay at the heart of Lewis's original formulation should be replaced with alternatives that are more sensitive to the role that laws play in scientific practice. Although the criteria that these philosophers put forward differ in a variety of ways, they are primarily concerned with the ability of laws to furnish us with predictions and encode information. This, I suggest, is a problem. If it is true that many scientific laws do not on their own perform some of the roles with which they are traditionally associated, then they are unlikely in isolation to make meaningful contributions to the predictive strength of a system or encode information about particular systems. Such laws are thus unlikely to end up in the best system, and so these accounts will have trouble conferring lawhood upon them. (shrink)

Laws of nature are properly (if controversially) conceived as abstract entities playing a governing role in the physical universe. Dispositionalists typically hold that laws of nature are not real, or at least are not fundamental, and that regularities in the physical universe are grounded in the causal powers of objects. By contrast, I argue that dispositionalism implies nomic realism: since at least some dispositions have ceteris paribus clauses incorporating uninstantiated universals, and these ceteris paribus clauses help to determine their dispositions' (...) ranges of manifestation, there are indeed abstracta which play a governing role in the physical universe. After addressing several objections (including the objection that such ‘laws’ lack sufficient independence/externality from the dispositions to count as genuinely governing), I go on to consider some broader implications of this conclusion for other debates in metaphysics and the philosophy of science.1.

Do facts about what an agent would freely do in certain circumstances at least partly determine any of her moral obligations? Actualists answer ‘yes’, while possibilists answer ‘no’. We defend two novel hybrid accounts that are alternatives to actualism and possibilism: Dual Obligations Hybridism and Single Obligation Hybridism. By positing two moral ‘oughts’, each account retains the benefits of actualism and possibilism, yet is immune from the prima facie problems that face actualism and possibilism. We conclude by highlighting one substantive (...) difference between our two hybrid accounts. (shrink)

There are four main theories concerning the ultimate constitution of matter: atomism version 1, atomism version 2, the theory of gunk, and the theory of extended simples. These four theories are usually seen as diametrically opposed. Here I take a stab at ecumenism, and argue that atomism version 1 and the theory of extended simples can be reconciled and rendered compatible by reference to the reality of dispositions.

The increasing preponderance of opinion that some natural phenomena can be explained mathematically has inspired a search for a viable account of distinctively mathematical explanation. Among the desiderata for an adequate account is that it should solve the problem of directionality and the reversals of distinctively mathematical explanations should not count as members among the explanatory fold but any solution must also avoid the exclusion of genuine explanations. In what follows, I introduce and defend what I refer to as a (...) quasi-erotetic solution which provides a remedy to the problem in the form of an additional necessary condition on explanation.

We examine the prevalent use of the phrase “local realism” in the context of Bell’s Theorem and associated experiments, with a focus on the question: what exactly is the ‘realism’ in ‘local realism’ supposed to mean? Carefully surveying several possible meanings, we argue that all of them are flawed in one way or another as attempts to point out a second premise (in addition to locality) on which the Bell inequalities rest, and (hence) which might be rejected in the face (...) of empirical data violating the inequalities. We thus suggest that the phrase ‘local realism’ should be banned from future discussions of these issues, and urge physicists to revisit the foundational questions behind Bell’s Theorem. (shrink)

Recently, Orilia and Oaklander have attempted to revive the so-called old tenseless theory of time, which most tenseless theorists themselves had given up as untenable, heralding the appearance of the so-called new tenseless theory.

Research misconduct is harmful because it threatens public health and public safety, and also undermines public confidence in science. Efforts to eradicate ongoing and prevent future misconduct are numerous and varied, yet the question of “what works” remains largely unanswered. To shed light on this issue, this study used data from both mail and online surveys administered to a stratified random sample of tenured and tenure-track faculty members (N = 613) in the social, natural, and applied sciences at America’s top (...) 100 research universities. Participants were asked to gauge the effectiveness of various intervention strategies: formal sanctions (professional and legal), informal sanctions (peers), prevention efforts (ethics and professional training), and reducing the pressures associated with working in research-intensive units. Results indicated that (1) formal sanctions received the highest level of support, (2) female scholars and researchers working in the applied sciences favored formal sanctions, and (3) a nontrivial portion of the sample supported an integrated approach that combined elements of different strategies. A key takeaway for university administrators is that a multifaceted approach to dealing with the problem of research misconduct, which prominently features enhanced formal sanctions, will be met with the support of university faculty.
