The overall aim of this article is to discuss how the MUSIC Model of Motivation can be applied to L2 instruction in a manner that is consistent with positive psychology, which emphasizes individuals’ strengths and the conditions in which they thrive. The article begins by describing the MUSIC model, which is a research-based framework that organizes strategies that instructors can use to motivate students to engage in learning. The MUSIC model can be used by L2 instructors to create learning experiences (...) that consider learners’ cognition, affect, needs, and desires in order to foster their motivation and engagement in L2 classes. The article also provides teaching strategies related to the MUSIC model and presents an assessment tool (the MUSIC Model of Academic Motivation Inventory) that can be used by L2 instructors to measure students’ MUSIC perceptions of their class. The assessment tool provides feedback to instructors that can be used to improve their instruction by incorporating strategies that allow their students to flourish. Examples of how the MUSIC Inventory can be used to assess L2 instruction are provided. Although researchers have examined the use of the MUSIC model in L2 classes, this research is underdeveloped, and many questions related to its use in L2 classes remain. The article concludes by proposing unanswered questions that could lead to more effective uses of the MUSIC model in L2 classes. (shrink)

Although philosophy courses are not known for hands-on learning activities in which students use, manipulate, or touch objects with their hands, there are simple hands-on activities that teachers can use to liven up their classrooms and foster active learning. In this paper I describe four activities I developed to attempt to improve student learning: GoldiLocke and the Three Buckets, The Argument From Disagreement Box, The Trolley Problem Reenactment, and The Lego Man of Theseus. I argue that such activities are (...) effective for two main reasons: they are fun; and they involve embodied learning. Finally, I offer some advice for developing hands-on learning activities for philosophy courses and share some of the ideas generated by session participants when I presented this material at the American Association of Philosophy Teachers Twentieth Biennial Workshop/Conference.

This essay seeks to contribute to the critical reception of Bloom’s Taxonomy of Educational Objectives by tracing the Taxonomy’s underlying philosophical assumptions. Identifying Bloom’s work as consistent with the legacy of Cartesian thought, I argue that its hierarchy of behavioral objectives provides a framework for certainty and communicability in ascertaining student learning. However, its implicit rejection of intuitive knowledge as well as its antagonism between the human subject and the known object promote the Enlightenment ideal of education as “intellectual work.” (...) When embodied in the Taxonomy, Cartesian assumptions foster a fundamental disposition in front of reality that is ultimately alienating. The paper begins with an explication of the Taxonomy’s affordances and philosophical assumptions. I then identify the Cartesian elements of these assumptions, particularly the Taxonomy’s inherent mind–body dualism and primacy of method. Finally, the paper employs these elements as an explanatory factor for the predominant critiques of the Taxonomy in educational theory literature. An addendum questions the possibility or plausibility of distance from objectives frameworks in the contemporary classroom. (shrink)

The Five Senses of Haiti discusses a series of medical mission trips by physicians and medical students to the Central Plateau of Haiti delivering care in the outpatient setting. Practitioners describe their experiences through the use of their five senses to draw contrast between modern health care and medical practice in the developing world. Physicians in a resource poor setting are left without the usual diagnostic armamentarium and the safeguards and distractions of the modern hospital setting. This deficit creates an (...) opportunity to devote time and focus to individual patients. Practicing medicine in this context clinicians use a heightened sense of awareness and increase their reliance on physical exam findings. Global medicine creates an opportunity for medical students to learn and physicians out of training to practice overlooked physical exam skills in the modern era. Physical exam findings and patient care yield diagnoses and fosters the bonds of the doctor-patient relationship. (shrink)

How aesthetics—understood as a more encompassing framework for human activity—might become the primary discourse for political and social engagement. These essays make the case for a reignited understanding of aesthetics—one that casts aesthetics not as illusory, subjective, or superficial, but as a more encompassing framework for human activity. Such an aesthetics, the contributors suggest, could become the primary discourse for political and social engagement. Departing from the “critical” stance of twentieth-century artists and theorists who embraced a counter-aesthetic framework for political (...) engagement, this book documents how a broader understanding of aesthetics can offer insights into our relationships not only with objects, spaces, environments, and ecologies, but also with each other and the political structures in which we are all enmeshed. The contributors—philosophers, media theorists, artists, curators, writers and architects including such notable figures as Jacques Rancière, Graham Harman, and Elaine Scarry—build a compelling framework for a new aesthetic discourse. The book opens with a conversation in which Rancière tells the volume's editor, Mark Foster Gage, that the aesthetic is “about the experience of a common world.” The essays following discuss such topics as the perception of reality; abstraction in ethics, epistemology, and aesthetics as the “first philosophy”; Afrofuturism; Xenofeminism; philosophical realism; the productive force of alienation; and the unbearable lightness of current creative discourse.

Truth by convention, once thought to be the foundation of a uniquely promising approach to explaining our access to the truth in nonempirical domains, is nowadays widely considered an absurdity. Its fall from grace has been due largely to the influence of an argument that can be sketched as follows: our linguistic conventions have the power to make it the case that a sentence expresses a particular proposition, but they can’t by themselves generate truth; whether a given proposition is true—and (...) so whether the sentence that expresses it is true—is a matter of what the world is like, which means it isn’t a matter of convention alone. The consensus is that this argument is decisive against truth by convention. Strikingly, though, it has rarely been formulated with much precision. Here I provide a new rendering of the argument, one that reveals its structure and makes transparent just what assumptions it requires, and then I assess conventionalists’ prospects for resisting each of those assumptions. I conclude that the consensus is mistaken: contrary to what is almost universally thought, there remains a promising way forward for the conventionalist project. Along the way, I clarify conventionalists’ commitments by thinking about what truth by convention would need to be like in order for conventionalism to do the epistemological work it’s intended to do.

A Benacerraf–Field challenge is an argument intended to show that common realist theories of a given domain are untenable: such theories make it impossible to explain how we’ve arrived at the truth in that domain, and insofar as a theory makes our reliability in a domain inexplicable, we must either reject that theory or give up the relevant beliefs. But there’s no consensus about what would count here as a satisfactory explanation of our reliability. It’s sometimes suggested that giving such (...) an explanation would involve showing that our beliefs meet some modal condition, but realists have claimed that this sort of modal interpretation of the challenge deprives it of any force: since the facts in question are metaphysically necessary and so obtain in all possible worlds, it’s trivially easy, even given realism, to show that our beliefs have the relevant modal features. Here I show that this claim is mistaken—what motivates a modal interpretation of the challenge in the first place also motivates an understanding of the relevant features in terms of epistemic possibilities rather than metaphysical possibilities, and there are indeed epistemically possible worlds where the facts in question don’t obtain.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Everyday Poetics: Logic, Love, and Ethics by Brett BourbonKatie PelkeyEveryday Poetics: Logic, Love, and Ethics by Brett Bourbon; 200 pp. London: Bloomsbury Publishing, 2022.In Everyday Poetics: Logic, Love, and Ethics, Brett Bourbon probes the nature of poetry and its centrality in our everyday lives, working from the ordinary-language philosophical framework associated with Ludwig Wittgenstein, J. L. Austin, W. V. O. Quine, and Stanley Cavell. Bourbon's (...) ideas contribute new dimensions to the elusive concept of poetry and pivots the reader's attention inward: how can we recognize poetry in our day-to-day and why should we? At sentence level, his claims are clear and compelling to readers across disciplines with varying knowledge of philosophy and poetry. This book is thus addressed to "poets, literary scholars, philosophers, and students of religion, and anyone who cares about the ethics of everyday life, about the surprises that punctuate and give our lives form" (p. ix).Poems themselves are such "events of form," Bourbon emphasizes, which live among us and need not be constituted by words. Wordless poems can be uncovered and embraced through the development of a "poetic vulnerability" to ordinary experiences that are not necessarily wedded to one's aesthetic reaction. Bourbon designates the alphabet as one such example of what he calls a "primal everyday poem"; the alphabet is wordless and consists of a patterned order whose mere form does not encompass its meaning. The ordinary expression "I love you" also falls under this classification; the phrase is a performative poem whose intricate connotation is simplified by common language, yet is not the equivalent of its mere words. Bourbon asserts that, like the phrase "I love you," poems of the everyday cannot be reduced to mere language, conditions, or creative modes.Of the ineffable nature of poetry, Bourbon claims, "Poetry, like death, is that which we can only know by analogy—by examples—but it has a scope beyond all our examples" (p. 108). In terms of examples, he draws from poignant personal experiences to reinforce his arguments and provide insight into his keen sensibility. In chapter 1 ("Poems of the Everyday"), Bourbon recounts his own dismissal as a young boy of poetry's worthiness until one day while watching an old film, he in fact was struck by the phrase "I love you." This ordinary phrase allowed him to reconsider the parameters of what constitutes poetry and acknowledge the dichotomy of the phrase's formal power constituted by trivial symbols.Chapter 4 ("Epithalamion") is also rooted in personal experience. Bourbon opens with the flat assertion, "I have never liked weddings" (p. 43), but he notes a difference between a "marriage of forms" and "marriage of intimacy and stability": his distaste is for the former. He believes that a successful marriage can become a poem of the everyday—an event of power and "linguistic surrogacy"—where the event itself fosters more meaning than the words alone [End Page 475] can carry. Marriage can be a poem of discovery that arises from the action of learning what it means to love. But in the objects of the wedding and all its trite, heart-shaped symbols, Bourbon remarks, no poems are to be found.Bourbon dedicates chapter 5 ("Is a Poem the Same as Its Words?") to his claim that what a poem is cannot be bound by its words entirely or by meaning alone. If one finds each line of a poem intelligible, that does not indicate that the poem's meaning is consequentially understood. Conversely, a reader may not know a poem's meaning with complete certainty; what is said may not illuminate what is meant. In Bourbon's explanation of the sentence as a model for how particular words construct a poem, he says that one must determine how such a sentence-poem would be meaningful through our own reading. He claims that a poem is more than its words and cannot be simplified into sets of sentences or phrases. "A poem, if it is a sentence, is always more than that sentence; otherwise, a poem would not be a poem but a sentence" (p. 67).Bourbon's latest publication challenges traditional, long... (shrink)

The frame problem refers to the fact that organisms must be able to zero in on relevant aspects of the world and intelligently ignore the vast majority of the world that is irrelevant to their goals. In this paper we aim to point out the connection between two leading frameworks for thinking about how organisms achieve this. Predictive processing is a rapidly growing framework within cognitive science which suggests that organisms assign a high ‘weight’ to relevant aspects of the world, (...) effectively treating relevant aspects of the world as if they are more precise. This assignment of weight is called precision-weighting and is the predictive processing account of how organisms allocate their attention. Relevance Realization is a framework that conceptualizes an organism’s ability to realize relevance as resulting from a dynamical system in which a cognitive agent makes use of opponent processing relationships to zero in on relevant aspects of the world. In this paper we use recent work on the diametric model of autism and psychosis to demonstrate that the tradeoffs inherent to precision-weighting are also inherent to relevance realization. This connection will demonstrate that although these frameworks have a different intellectual background and use a different set of concepts and vocabulary, they are both pointing to the same underlying process. The fact that these different frameworks have converged on such a similar solution to the problem of how organisms realize relevance serves to demonstrate the plausibility of that solution. (shrink)

The notion of a genetic program has been widely criticized by both biologists and philosophers. But the debate has revolved around a narrow conception of what programs are and how they work, and many criticisms are linked to this same conception. To remedy this, I outline a modern and more apt idea of a program that possesses many of the features critics thought missing from programs. Moving away from over-simplistic conceptions of programs opens the way to a more fruitful interplay (...) of ideas between the complexity of biology and our most complex engineering discipline.

This article proposes that Horace's Epodes and Ovid's Metamorphoses open with significant acrostics that comprise the first two letters, in some cases forming syllables, of successive lines: IB-AM/IAMB (Epod. 1.1–2) and IN-CO-(H)AS (Met. 1.1–3). Each acrostic, it will be argued, tees up programmatic concerns vital to the work it opens: generic identity and the interrelation of form and content (Epodes), etymology and monumentality (Metamorphoses). Moreover, as befits their placement at the head of collections, both acrostics negotiate the challenge of literary (...) commencement. The introduction reviews recent developments in acrostic studies and discusses important predecessors and parallels for Horace's and Ovid's ‘two-letter’ and syllabic acrostics. Two subsequent sections examine the acrostics singly, and a conclusion compares the dialogues that these acrostics open between author and reader, underscoring the welcome challenge which Ovid's acrostic offers to the prevailing scholarly view that this form of wordplay is a strictly visual affair.

Drawing on recent advances in evolutionary biology, prominent scholars return to the question posed in a pathbreaking book: how evolution itself evolved.

This paper argues that Friedrich Nietzsche was a mystic and that his post-Gay Science (1882) thought should be understood as an unfolding expression of his mystical experiences. Drawing on Nietzsche’s Nachlass (notes), letters, and published writings, I show that he undoubtedly had at least two major mystical experiences and that these experiences were the source of all the cardinal motifs of his later thought. The apparent tensions or paradoxes between Nietzsche’s cardinal teachings, above all that between the superman and the (...) eternal recurrence, are resolved once they are understood as products of a mystical epistemology derived from an intuitive source of knowledge purportedly beyond the dualities intrinsic to ordinary modes of cognition. This intuitio mystica, which Nietzsche declared to be the real purpose of all philosophy, is coextensive with a type of mysticism I call apotheosis, based on the individual ego’s identification with a unity underlying all reality.

I argue that Quinean naturalists’ holism-based arguments against analyticity and apriority are more difficult to resist than is generally supposed, for two reasons. First, although opponents of naturalism sometimes dismiss these arguments on the grounds that the holistic premises on which they depend are unacceptably radical, it turns out that the sort of holism required by these arguments is actually quite minimal. And second, although it’s true, as Grice and Strawson pointed out long ago, that these arguments can succeed only (...) if there isn’t any principled criterion for meaning change, such a criterion turns out to be hard to come by. David Chalmers has recently argued that such a criterion must exist, since the norms governing belief revision are subject to obvious exceptions that can be explained only by appeal to meaning change. But this, I argue, is incorrect: if choices about how to use language are themselves rationally assessable, then there are no such exceptions to be explained. To show that this is so, I formulate a new kind of coherence norm that may be useful for reasoning formally about the relationship between meaning and evidence. (shrink)

The literature contains evidence from some studies of asymmetric patterns of choice cycles in the direction consistent with regret theory, and evidence from other studies of asymmetries in the opposite direction. This article reports an experiment showing that both patterns occur within the same sample of respondents operating in the same experimental environment. We discuss the implications for modelling behaviour in such environments.

Every day, new warnings emerge about artificial intelligence rebelling against us. All the while, a more immediate dilemma flies under the radar. Have forces been unleashed that are thrusting humanity down an ill-advised path, one that's increasingly making us behave like simple machines? In this wide-reaching, interdisciplinary book, Brett Frischmann and Evan Selinger examine what's happening to our lives as society embraces big data, predictive analytics, and smart environments. They explain how the goal of designing programmable worlds goes hand (...) in hand with engineering predictable and programmable people. Detailing new frameworks, provocative case studies, and mind-blowing thought experiments, Frischmann and Selinger reveal hidden connections between fitness trackers, electronic contracts, social media platforms, robotic companions, fake news, autonomous cars, and more. This powerful analysis should be read by anyone interested in understanding exactly how technology threatens the future of our society, and what we can do now to build something better. (shrink)

Emotion Review, Volume 14, Issue 3, Page 167-181, July 2022. A growing cadre of influential scholars has converged on a circumscribed definition of empathy as restricted only to feeling the same emotion that one perceives another is feeling. We argue that this restrictive isomorphic matching definition is deeply problematic because it deviates dramatically from traditional conceptualizations of empathy and unmoors the construct from generations of scientific research and clinical practice; insistence on an isomorphic form undercuts much of the functional value (...) of empathy from multiple perspectives of analysis; and combining the opposing concepts of isomorphic matching and self-other awareness implicitly requires motivational content, causing the RIM definition to implicitly require the kind of non-matching emotional content that it explicitly seeks to exclude.

Sensitivity has sometimes been thought to be a highly epistemologically significant property, serving as a proxy for a kind of responsiveness to the facts that ensure that the truth of our beliefs isn’t just a lucky coincidence. But it's an imperfect proxy: there are various well-known cases in which sensitivity-based anti-luck conditions return the wrong verdicts. And as a result of these failures, contemporary theorists often dismiss such conditions out of hand. I show here, though, that a sensitivity-based understanding of (...) epistemic luck can be developed that respects what was attractive about sensitivity-based approaches in the first place but that's immune to these failures.

When epistemologists talk about knowledge, the discussions traditionally include only a small class of other epistemic notions: belief, justification, probability, truth. In this paper, we propose that epistemologists should include an additional epistemic notion into the mix, namely the notion of assuming or taking for granted.

Which rules should guide our reasoning? Human reasoners often use reasoning shortcuts, called heuristics, which function well in some contexts but lack the universality of reasoning rules like deductive implication or inference to the best explanation. Does it follow that human reasoning is hopelessly irrational? I argue: no. Heuristic reasoning often represents human reasoners reaching a local rational maximum, reasoning more accurately than if they try to implement more “ideal” rules of reasoning. I argue this is a genuine rational achievement. (...) Our ideal rational advisors would advise us to reason with heuristic rules, not more complicated ideal rules. I argue we do not need a radical new account of epistemic norms to make sense of the success of heuristic reasoning. (shrink)

When government actors seek to restrict the sale of hazardous substances, industry actors tend to intervene, deploying coordinated strategies aimed at delaying, preventing or weakening attempts to regulate their products. In many cases, this has involved deliberate efforts to obfuscate science, mislead the public and manipulate political actors in order to ensure desired policy outcomes. Strategies of regulatory obstructionism have resulted in the prolonged dispersal of harmful chemical substances with tangible impacts on public health. This article proposes that this behavior (...) should be interpreted as a form of violence. Examining the regulatory histories of lead, benzene, asbestos and PCBs, the article demonstrates how regulatory obstructionism and violence have become intractable characteristics of the chemical industry.

Dictionary-making is an increasingly important avenue for cultural preservation and maintenance for Aboriginal people. It is also one of the main jobs performed by linguists working in Aboriginal communities. However, current tools for making dicitionaries are either not specifically designed for the purpose (Word, Nisus), with the result that dictionaries written in them are difficult to maintain, to keep consistent, and to manipulate automatically, or are too complex for many people to use (Shoebox), and are thereby wasted as potential resources. (...) Moreover, neither of these sets of tools provides a suitable user interface for people who simply want to browse or find words in a dictionary. We set out to design a dictionary 'template', written in software that was easy (and fun!) for people to use, and that maintained a consistent relationship among the information in the dictionary.

A funny, sharp and smart picture book to help mommy and daddy through difficult moments.

This paper describes a pattern of explanation prevalent in the biological sciences that I call a ‘lineage explanation’. The aim of these explanations is to make plausible certain trajectories of change through phenotypic space. They do this by laying out a series of stages, where each stage shows how some mechanism worked, and the differences between each adjacent stage demonstrates how one mechanism, through minor modifications, could be changed into another. These explanations are important, for though it is widely accepted (...) that there is an ‘incremental constraint’ on evolutionary change, in an important class of cases it is difficult to see how to satisfy this constraint. I show that lineage explanations answer important questions about evolutionary change, but do so by demonstrating differences between individuals rather than invoking population processes, such as natural selection.1.

Why can I not appropriately utter ‘It must be raining’ while standing outside in the rain, even though every world consistent with my knowledge is one in which it is raining? The common response to this problem is to hold that epistemic must, in addition to quantifying over epistemic possibilities, carries some additional evidential information concerning the source of one'S evidence. I argue that this is a mistake: epistemic modals are mere quantifiers over epistemic possibilities. My central claim is that (...) the seeming anomaly of the data above arises from a mistaken conception of what a possibility is. Instead of conceiving of possibilities as possible worlds, I argue that we should conceive of possibilities as answers to open questions. (shrink)

It is commonly held that the context with respect to which an indexical is interpreted is determined independently of the interpretation of the indexical. This view, which I call Context Realism, has explanatory significance: it is because the context is what it is that an indexical refers to what it does.

I then develop an alternative that I call Context Constructivism, according to which indexicals are defined not in terms of (...) features of utterance situations, but rather in terms of roles that objects could play.

Like Laland et al., I think Mayr’s distinction is problematic, but I identify a further problem with it. I argue that Mayr’s distinction is a false dichotomy, and obscures an important question about evolutionary change. I show how this question, once revealed, sheds light on some debates in evo-devo that Laland et al.’s analysis cannot, and suggest that it provides a different view about how future integration between biological disciplines might proceed.

Understanding how cooperation evolves is central to explaining some core features of our biological world. Many important evolutionary events, such as the arrival of multicellularity or the origins of eusociality, are cooperative ventures between formerly solitary individuals. Explanations of the evolution of cooperation have primarily involved showing how cooperation can be maintained in the face of free-riding individuals whose success gradually undermines cooperation. In this paper I argue that there is a second, distinct, and less well explored, problem of cooperation (...) that I call the generation of benefit. Focusing on how benefit is generated within a group poses a different problem: how is it that individuals in a group can (at least in principle) do better than those who remain solitary? I present several different ways that benefit may be generated, each with different implications for how cooperation might be initiated, how it might further evolve, and how it might interact with different ways of maintaining cooperation. I argue that in some cases of cooperation, the most important underlying “problem” of cooperation may be how to generate benefit, rather than how to reduce conflict or prevent free-riding. (shrink)

While research has focused on why certain entrepreneurs elect to create innovative solutions to social problems, very little is known about why some social entrepreneurs choose to scale their solutions while others do not. Research on scaling has generally focused on organizational characteristics often overlooking factors at the individual level that may affect scaling decisions. Drawing on the multidimensional construct of moral intensity, we propose a theoretical model of ethical decision making to explain why a social entrepreneur’s perception of moral (...) intensity of the social problem, coupled with their personal desire for control, can significantly influence scaling decisions. Specifically, we propose that higher levels of perceived moral intensity will positively influence the likelihood of scaling through open as opposed to closed modes in order to achieve greater speed and scope of social impact. However, we also propose this effect will be negatively moderated by a social entrepreneur’s higher levels of desire for control. Our model has implications for research and practice at the interface of ethics and social entrepreneurship. (shrink)

The dual-use issue is often framed as a series of paralyzing ‘dilemmas’ facing the scientific community as well as institutions which support innovation. While this conceptualization of the dual-use issue can be useful in certain contexts its usefulness is more limited when reflecting on the governance and politics of the dual-use issue. Within this paper, key shortcomings of the dilemma framing are outlined. It is argued that many of the issues raised in the most recent debates about ‘dual-use’ bird flu (...) research remain unresolved. This includes questions about the trajectories of certain lines of research, as well as broader trends in the practice and governance of science. This leads to difficult questions about current approaches to the dual-use issue within the US, as well as internationally. (shrink)

Comparing engineering to evolution typically involves adaptationist thinking, where well-designed artifacts are likened to well-adapted organisms, and the process of evolution is likened to the process of design. A quite different comparison is made when biologists focus on evolvability instead of adaptationism. Here, the idea is that complex integrated systems, whether evolved or engineered, share universal principles that affect the way they change over time. This shift from adaptationism to evolvability is a significant move for, as I argue, we can (...) make sense of these universal principles without making any adaptationism claims. Furthermore, evolvability highlights important aspects of engineering that are ignored in the adaptationist debates. I introduce some novel engineering examples that incorporate these key neglected aspects, and use these examples to challenge some commonly cited contrasts between engineering and evolution, and to highlight some novel resemblances that have gone unnoticed.

Humans’ indigenous microbes strongly influence organ functions in an age‐ and diet‐dependent manner, adding an important dimension to aging biology that remains poorly understood. Although age‐related differences in the gut microbiota composition correlate with age‐related loss of organ function and diseases, including inflammation and frailty, variation exists among the elderly, especially centenarians and people living in areas of extreme longevity. Studies using short‐lived as well as nonsenescent model organisms provide surprising functional insights into factors affecting aging and implicate attenuating effects (...) of microbes as well as a crucial role for certain transcription factors like forkhead box O. The unexpected beneficial effects of microbes on aged animals imply an even more complex interplay between the gut microbiome and the host. The microbiome constitutes the major interface between humans and the environment, is influenced by biosocial stressors and behaviors, and mediates effects on health and aging processes, while being moderated by sex and developmental stages.

I use some recent formal work on measuring causation to explore a suggestion by James Woodward: that the notion of causal specificity can clarify the distinction in biology between permissive and instructive causes. This distinction arises when a complex developmental process, such as the formation of an entire body part, can be triggered by a simple switch, such as the presence of particular protein. In such cases, the protein is said to merely induce or "permit" the developmental process, whilst the (...) causal "instructions" for guiding that process are already prefigured within the cells. I construct a novel model that expresses in a simple and tractable way the relevant causal structure of biological development and then use a measure of causal specificity to analyse the model. I show that the permissive-instructive distinction cannot be captured by simply contrasting the specificity of two causes as Woodward proposes, and instead introduce an alternative, hierarchical approach to analysing the interaction between two causes. The resulting analysis highlights the importance of focusing on gene regulation, rather than just the coding regions, when analysing the distinctive causal power of genes. (shrink)

Recent work by Brian Skyrms offers a very general way to think about how information flows and evolves in biological networks—from the way monkeys in a troop communicate to the way cells in a body coordinate their actions. A central feature of his account is a way to formally measure the quantity of information contained in the signals in these networks. In this article, we argue there is a tension between how Skyrms talks of signalling networks and his formal measure (...) of information. Although Skyrms refers to both how information flows through networks and that signals carry information, we show that his formal measure only captures the latter. We then suggest that to capture the notion of flow in signalling networks, we need to treat them as causal networks. This provides the formal tools to define a measure that does capture flow, and we do so by drawing on recent work defining causal specificity. Finally, we suggest that this new measure is crucial if we wish to explain how evolution creates information. For signals to play a role in explaining their own origins and stability, they can’t just carry information about acts; they must be difference-makers for acts. _1_ Signalling, Evolution, and Information _2_ Skyrms’s Measure of Information _3_ Carrying Information versus Information Flow _3.1_ Example 1 _3.2_ Example 2 _3.3_ Example 3 _4_ Signalling Networks Are Causal Networks _4.1_ Causal specificity _4.2_ Formalizing causal specificity _5_ Information Flow as Causal Control _5.1_ Example 1 _5.2_ Examples 2 and 3 _5.3_ Average control implicitly ‘holds fixed’ other pathways _6_ How Does Evolution Create Information? _7_ Conclusion Appendix >.

Ordinarily, people take themselves to know a lot. I know where I was born, I know that I have two hands, I know that two plus two equals four, and I also think I know a lot of other stuff too. However, the project of trying to provide a philosophically satisfying account of knowledge, one that holds up against skeptical challenges, has proven surprisingly difficult. Either one aims for an account of justification (and knowledge) that is epistemologically demanding, in an (...) effort to offer an account that satisfactorily addresses skepticism, or one aims for an account of justification (and knowledge) that makes sense of our ordinary knowledge claims. However, the history of contemporary epistemology tells us that you cannot have both: the former results in skepticism, the latter in an unsatisfying response to skepticism. -/- What we find, in the array of contemporary attempts to give accounts of knowledge and justification, are numerous views spread across the internalism/externalism spectrum that deal with the dilemma of the previous paragraph in different ways. Most of them are guided by the goal of accommodating our ordinary knowledge claims. This is especially true of externalist accounts, but many internalist accounts are guided by this same goal, though perhaps to a lesser degree. One kind of internalist view stands out for its insistence on providing philosophically satisfying accounts of knowledge and justification, even if doing so has skeptical implications. This is the traditional, old-fashioned, Cartesian-style internalism that was so prominent in the early 20th century and is now a minority position. -/- Unlike competing versions of epistemic internalism, the guiding principle of traditional, Cartesian-style internalism (what I will henceforth call ‘traditional internalism’) is not to accommodate our commonsense views about the rationality of our ordinary beliefs. Instead, traditional internalism emphasizes rationality’s demand for philosophical assurance, on the basis of evidence that can withstand the strongest skeptical challenges, that our ordinary beliefs (perceptual and otherwise) are true. According to the traditional internalist, the philosopher, qua philosopher, ought to begin the epistemological project from the inside, placing a premium on satisfying our philosophical curiosity. -/- Despite the relative unpopularity of traditional internalism the view can be taken to be worthy of attention for a variety of reasons. First, traditional internalism has great historical importance. Significant portions of the history of contemporary epistemology, and to a lesser degree philosophy in the modern era (roughly, Descartes to Kant), are grounded in a number of the intuitions that drive traditional internalism. Second, and perhaps even more importantly, traditional internalism serves as the source of a wide variety of criticisms for other, more prominent, contemporary epistemological views. In a number of debates the views of the traditional internalist are used to play a kind of Devil’s advocate. Finally, some of the ideas that ground traditional internalism have had a bit of resurgence of late.1 To put it simply, traditional internalism refuses to go away. In this introduction, I will do three things. First, I will situate traditional internalism among other competing versions of internalism by highlighting the ways in which traditional internalism differs from them (in particular, evidentialism and conservatism). Second, I will explain more carefully some of the central tenets of traditional internalism and what motivates them. Third, I will highlight some of the difficulties that threaten traditional internalism, and I will explain how the contributions to this volume interact with those difficulties. -/- The goal of this volume is to test again the staying power of traditional internalism, to see if this once historically prominent view deserves another look, to see if traditional internalism is a legitimate contender providing useful criticisms of more prominent views, or, if instead it is time for traditional internalism to be left by the wayside.
