Gilroy and Wade wrote 20 years ago that every policy presupposes an underlying moral argument that justifies it. This claim is now rarely contested: policy making is an inescapably moral enterprise...

The essentialism story is a version of the history of biological classification that was fabricated between 1953 and 1968 by Ernst Mayr, who combined contributions from Arthur Cain and David Hull with his own grudge against Plato. It portrays pre-Darwinian taxonomists as caught in the grip of an ancient philosophy called essentialism, from which they were not released until Charles Darwin's 1859 Origin of Species. Mayr's motive was to promote the Modern Synthesis in opposition to the typology of idealist morphologists; (...) demonizing Plato served this end. Arthur Cain's picture of Linnaeus as a follower of 'Aristotelian' (scholastic) logic was woven into the story, along with David Hull's application of Karl Popper's term, 'essentialism', which Mayr accepted in 1968 as a synonym for what he had called 'typological thinking'. Although Mayr also pointed out the importance of empiricism in the history of taxonomy, the essentialism story still dominates the secondary literature. The history of the first telling of the essentialism story exposes its scant basis in fact. (shrink)

Mares and Goldblatt, 163–187, 2006) provided an alternative frame semantics for two quantified extensions of the relevant logic R. In this paper, I show how to extend the Mares-Goldblatt frames to accommodate identity. Simpler frames are provided for two zero-order logics en route to the full logic in order to clarify what is needed for identity and substitution, as opposed to quantification. I close with a comparison of this work with the Fine-Mares models for relevant logics with identity and a (...) discussion of constant and variable domains. (shrink)

The current widespread belief that taxonomic methods used before Darwin were essentialist is ill-founded. The essentialist method developed by followers of Plato and Aristotle required definitions to state properties that are always present. Polythetic groups do not obey that requirement, whatever may have been the ontological beliefs of the taxonomist recognizing such groups. Two distinct methods of forming higher taxa, by chaining and by examplar, were widely used in the period between Linnaeus and Darwin, and both generated polythetic groups. Philosopher (...) William Whewell congratulated pre-Darwinian taxonomists for not adhering to the rigid ideal of definition used in the mathematical sciences. What he called the method of types is here called the method of exemplars because typology has been equated with essentialism, whereas the use of a type species as the reference point or prototype for a higher category was a practice inconsistent with essentialism. The story that the essentialism of philosophers dominated the development of systematics may prove to be a myth. (shrink)

This paper will develop ideas from [44]. We will generalize their work in two directions. First, we provide axioms for justification logics over the base logic B and show that the logic permits a proof of the internalization theorem. Second, we provide alternative frames that more closely resemble the standard versions of the ternary relational frames, as well as a more general approach to the completeness proof. We prove that soundness and completeness hold for justification logics over a wide variety (...) of base logics. Finally, we will strengthen Belnap’s variable sharing for the justification logic context, demonstrating that the justifications are properly relevant justifications. (shrink)

In this paper, we build on earlier work by Standefer (Logic J IGPL 27(4):543–569, 2019) in investigating extensions of substructural logics, particularly relevant logics, with the machinery of justification logics. We strengthen a negative result from the earlier work showing a limitation with the canonical model method of proving completeness. We then show how to enrich the language with an additional operator for implicit commitment to circumvent these problems. We then extend the logics with axioms for D, 4, and 5, (...) which requires additional justification term operators, following the work of Pacuit (in proceedings of the fifth panhellenic logic symposium, 2005) and Rubtsova (in Grigoriev D, Harrison J (eds) Computer science—theory and applications, CSR 2006; J Logic Comput 16(5):671–684, 2006), and present the required modifications to the frame semantics. We present a simplification of the neighborhood frames from the earlier work and we close by investigating the distinctive contribution of the + operator to the logic. (shrink)

In this paper, I motivate the addition of an actuality operator to relevant logics. Straightforward ways of doing this are in tension with standard motivations for relevant logics, but I show how to add the operator in a way that permits one to maintain the intuitions behind relevant logics. I close by exploring some of the philosophical consequences of the addition.

One of the many claims about the value of local food is that local food exchanges generate trust between producers and consumers. To what degree is this actually the case and how does such trust develop? Drawing on interview and fieldwork data in one local food system in the Northeastern U.S., I show how local food participants build trust and reciprocity with one another in order to mitigate the challenges imposed by the conventional system. This trust and reciprocity builds primarily (...) through three mechanisms: reliable, positive relationships; demonstrations of good will toward one another; and a shared understanding of the value of locally-oriented food. Through these mechanisms, local food operators are able to build a healthy, stable local food system, able to better resist the pressures of the conventional system in which it must continually operate.

Growth in CSR-washing claims in recent decades has been dramatic in numerous academic and activist contexts. The discourse, however, has been fragmented, and still lacks an integrated framework of the conditions necessary for successful CSR-washing. Theorizing successful CSR-washing as the joint occurrence of five conditions, this paper undertakes a literature review of the empirical evidence for and against each condition. The literature review finds that many of the conditions are either highly contingent, rendering CSR-washing as a complex and fragile outcome. (...) This finding runs counter to the dominant perception in the general public, among activists, and among a vocal contingent of academics that successful CSR-washing is rampant. (shrink)

We present an extension of the basic revision theory of circular definitions with a unary operator, □. We present a Fitch-style proof system that is sound and complete with respect to the extended semantics. The logic of the box gives rise to a simple modal logic, and we relate provability in the extended proof system to this modal logic via a completeness theorem, using interpretations over circular definitions, analogous to Solovay’s completeness theorem forGLusing arithmetical interpretations. We adapt our proof to (...) a special class of circular definitions as well as to the first-order case. (shrink)

Reading the Shape of Nature vividly recounts the turbulent early history of the Museum of Comparative Zoology at Harvard and the contrasting careers of its founder Louis Agassiz and his son Alexander. Through the story of this institution and the individuals who formed it, Mary P. Winsor explores the conflicting forces that shaped systematics in the second half of the nineteenth century. Debates over the philosophical foundations of classification, details of taxonomic research, the young institution's financial struggles, and the (...) personalities of the men most deeply involved are all brought to life. In 1859, Louis Agassiz established the Museum of Comparative Zoology to house research on the ideal types that he believed were embodied in all living forms. Agassiz's vision arose from his insistence that the order inherent in the diversity of life reflected divine creation, not organic evolution. But the mortar of the new museum had scarcely dried when Darwin's Origin was published. By Louis Agassiz's death in 1873, even his former students, including his son Alexander, had defected to the evolutionist camp. Alexander, a self-made millionaire, succeeded his father as director and introduced a significantly different agenda for the museum. To trace Louis and Alexander's arguments and the style of science they established at the museum, Winsor uses many fascinating examples that even zoologists may find unfamiliar. The locus of all this activity, the museum building itself, tells its own story through a wonderful series of archival photographs. (shrink)

In classically based modal logic, there are three common conceptions of necessity, the universal conception, the equivalence relation conception, and the axiomatic conception. They provide distinct presentations of the modal logic S5, all of which coincide in the basic modal language. We explore these different conceptions in the context of the relevant logic R, demonstrating where they come apart. This reveals that there are many options for being an S5-ish extension of R. It further reveals a divide between the universal (...) conception of necessity on the one hand, and the axiomatic conception on the other: The latter is consistent with motivations for relevant logics while the former is not. For the committed relevant logician, necessity cannot be the truth in all possible worlds. (shrink)

This article responds to critical views of John Rhym, Martin Rossouw, Ludo de Roo, and Annie Sandrussi on my 2017 book Phenomenology of Film: A Heideggerian Account of the Film Experience. The article also takes up positive footholds from the analyses of Chiara Quaranta and Jason Wirth. The main topics addressed include Martin Heidegger’s ontic-ontological distinction; the notion of film-as-philosophy; being-in-the-world read as being-in-the-film-world; and questions surrounding the facticity and identity of the film viewer.

This essay dates portions of the “Burden of Egypt” prophecy in Isaiah 19 to the Neo-Assyrian period, based on its borrowing of motifs from Assyrian royal inscriptions. These include the unique motif of the establishment of a monument on the border with Egypt and Assyrian attempts to dominate Egypt by controlling its trade. The essay also demonstrates the dependence of parts of Isaiah 19 on material in Exodus 1–15, integrating specific phrases from these Exodus chapters with motifs known to us (...) from Assyrian royal inscriptions. This integration could only have taken place during the Assyrian period, and this has obvious implications for the dating of the Exodus text. The essay understands the prophecy as a re-envisioning of the Assyrian campaign of 734, part of which was directed at Egypt. In this re-envisioned campaign, YHWH Himself is directing the Assyrian attack on Egypt. The essay focusses on 19:19–25, which describe how the Egyptians suffer as a result of the Assyrian attack. In their despair, they acknowledge the sovereignty of YHWH. This recognition is based on the Assyrian model of recognizing the Assyrian king as universal sovereign, and the monument described in v. 22 is based on the monument established by the Assyrians on the Egyptian border. The behavior of the Egyptians in vv. 20–22 provokes the unique theological statements of vv. 23–25, in which Egypt and Assyria join Israel in the triad blessed by YHWH. This passage demonstrates Isaiah’s use of a sort of “replacement theology” in which the universal sovereignty of YHWH is imagined and described based on Assyrian claims of universal dominion.

The recent outbreak of Ebola in West Africa has killed thousands of people, including healthcare workers. African responses have been varied and largely ineffective. The WHO and the international community’s belated responses have yet to quell the epidemic. The crisis is characteristic of a failure to properly comply with the International Health Regulations 2005. More generally, it stems from a failure of international health justice as articulated by a range of legal institutions and instruments, and it should prompt us to (...) question the state and direction of approaches to the governance of global public health. This paper queries what might be done to lift global public health as a policy arena to the place of prominence that it deserves. It argues that there are at least two critical reasons for the past, present and easily anticipated future failings of the global public health regime. After exploring those, it then articulates a new way forward, identifying three courses of action that might be adopted in realising better health outcomes and global health justice, namely value, institutional and legal reform.

Between 1937 and 1940 the Taxonomic Principles Committee of the newly-founded Association for the Study of Systematics in Relation to General Biology (later the Systematics Association) attempted to define the relationship between evolution and taxonomy. The people who took part in the discussion were W.T. Calman, C.R.P. Diver, J.S.L. Gilmour, J.S. Huxley, W.D. Lang, J.R. Norman, R. Melville, O.W. Richards, M.A. Smith, T.A. Sprague, H. Hamshaw Thomas, W.B. Turrill, B.P. Uvarov, A.F. Watkins, E.I. White, and A.J. Wilmott. Most of the (...) botanists asserted that taxonomy was a practical matter to be kept distinct from phylogenetic speculation, and most of the zoologists insisted that taxonomists must strive to represent evolution if they wished to be scientific. The disagreement seemed to be hardening rather than approaching compromise when World War Two stopped the committee's work. (shrink)

Science matters. Science matters to the development of knowledge, to the sustainability of development, and to the shaping of social mores. Countries transitioning from developing to developed must be prepared to make science work for them and to forge a vision to become competitors in some aspects of science innovation. Drawing on data generated by the “Governing Emerging Technologies: Social Values and Stem Cell Regulation in Argentina” Project, this paper places the current Argentine bioscience setting in context by reviewing the (...) development of biosciences in Argentina, explores understandings of the social dimensions of bioscience innovation in Argentina and the possibilities of enhancing public support for science, and offers some preliminary thoughts on a model for socio-legal activity directed at encouraging social engagement with and the uptake of high technologies in Argentina.

This article explores the thought of Tomasso de Vio, Cardinal Cajetan, on grace, justification and merit, situating his position vis-à-vis medieval, Reformation, and modern interlocutors. It examines a wide spectrum of Cajetan's works including his commentary on the Summa theologiae, the controversial work De fide et operibus contra Lutheranos, and his biblical commentaries on Matthew and Romans. It makes the argument that Cajetan preserves a Thomist perspective on grace and human action as they pertain to justification and salvation; that is, (...) Cajetan denies merit to any human action preceding justification but allows for restricted instances of merit for persons in a state of grace. The study examines potentially divergent positions in Cajetan's works and argues for overall consistency. In doing so, it presents Cajetan's thought on doctrinal issues which unfolded during the Reformation and persisted in the modern period. (shrink)

The results of Vatican II for the study of Scripture produced both expected and unexpected fruits. Those combined fruits provide the opportunity for some reflection on the current status of biblical scholarship in relation to the Church. This current status helps identify what we must appreciate and celebrate, but also helps identify remaining gaps to be filled. By assessing some of the gaps, the fruits of the second Vatican council are used to provide one way of approaching these remaining gaps, (...) and charting a hopeful way ahead. (shrink)

One of the central issues of contemporary philosophy and biology is the nature of communication. Early accounts of communication tended to focus on just one side of the communicative divide – the speaker side or the receiver side – and took as their starting point the case of human language. Animal communication, historically, was largely treated as a special case. Now things are different. Now it appears we might have a model that makes sense of sign use in both the (...) human and animal realms and brings together both sides of the signaling divide. It’s still to be seen, however, how much the model actually captures, especially the farther down we go on the animal side, and it’s still to be seen how well the model captures the human cases, especially those around the edges. The purpose of this thesis is to explore the foundations of the sender-receiver model and to show that it can cover more than was previously imagined. Topics discussed include the nature of communication and signaling, animal communication, the nature of meaning or content, the communicative nature of objects such as works of art, blueprints, and maps, and the possibility of communication between groups and collective agents.

This paper addresses the question of how local can be defined in practice. It contributes to the growing literature on local food systems and particularly our understanding of what counts as local and the elements that influence those contours. While most of our conceptions of local food tend to rely on an articulation of either proximity traveled or relationship between entities, I argue that a more nuanced and complete understanding must take account of both of these aspects. I draw on (...) a dataset of locally oriented farm and food-related establishments in southern New England to identify how far local food travels in this region and how interconnected local food establishments are with one another and use these and other measures to tease out the tension between proximity and relationship as measures of local. I find that these two aspects not only are connected to each other in a complex dynamic, but also are bound up with other structural factors as well. (shrink)

There appears to be few, if any, limits on what sorts of logical connectives can be added to a given logic. One source of potential limitations is the motivating ideology associated with a logic. While extraneous to the logic, the motivating ideology is often important for the development of formal and philosophical work on that logic, as is the case with intuitionistic logic. One family of logics for which the philosophical ideology is important is the family of relevant logics. In (...) this paper, I explore the limits of what a relevant connective is, showing how some basic criteria motivated by the ideology of relevant logicians provide robust limits on potential connectives. These criteria provide some plausible necessary conditions on being a relevant connective. (shrink)

The current picture of the history of taxonomy incorporates A. J. Cain's claim that Linnaeus strove to apply the logical method of definition taught by medieval followers of Aristotle. Cain's argument does not stand up to critical examination. Contrary to some published statements, there is no evidence that Linnaeus ever studied logic. His use of the words “genus” and “species” ruined the meaning they had in logic, and “essential” meant to him merely “taxonomically useful.” The essentialism story, a narrative that (...) has most pre-Darwinian biologists steeped in the world view of Plato and Aristotle, is ill-founded and improbable.

Two common forms of natural deduction proof systems are found in the Gentzen–Prawitz and Jaśkowski–Fitch systems. In this paper, I provide translations between proofs in these systems, pointing out the ways in which the translations highlight the structural rules implicit in the systems. These translations work for classical, intuitionistic, and minimal logic. I then provide translations for classical S4 proofs.

Functionalist accounts of blame have been rising in popularity. Proponents of the approach claim that, by defining blame in terms of its function or functions, their account has the advantage of being able to accommodate a wide range of attitudes and activities as blame; but their opponents question the extensional and explanatory adequacy of such accounts. This paper contributes to this burgeoning literature by presenting new challenges to the existing functionalist accounts. The fundamental problem, I shall argue, lies in the (...) fact that they all focus on using functions to define blame as a type of practice, but this strategy fails to pick out a unique moral-psychological type and does not offer a complete set of extension-determining criteria for the concept of blame. This amounts to a serious theoretical disadvantage. I consider various responses to the challenges throughout the paper, concluding that the best reply available to the functionalist theorist involves using functions to directly define blame tokens.

This article examines selected texts in which Martin Heidegger thematizes the ontology of images, in order to adduce a view of how he under­stands their merits and limitations. I am primarily interested in the images seen in art works, especially those in film and photography, given Heidegger’s strong criticism of the latter alongside other 20th-century communicative media. The goal of the article is not to determine what is Heidegger’s central or overall position regarding images, as it is not clear that (...) he has such a position. Rather, the goal is to analyze how his various statements on images, as well as imagination, fit together. I contrast Heidegger’s critical views in “The Age of the World Picture” with other texts in which he describes images more favorably. I also devote some space to texts in which Heidegger treats imagination and the origin of images more broadly. (shrink)

According to the response-dependence view of moral responsibility, a person is morally responsible just in case, and in virtue of the fact that, she is an appropriate target for reactive attitudes. This paper raises a new puzzle regarding response-dependence: there is a mismatch between the granularity of the reactive attitudes and of responsibility facts. Whereas the reactive attitudes are comparatively coarse-grained, responsibility facts can be quite fine-grained. This poses a challenge for response-dependence, which seeks to ground facts about responsibility in (...) facts about the reactive attitudes. Specifically, reactive attitudes are not enough for grounding facts about degrees of moral responsibility. The responsedependence view thus requires significant revisions or supplementations.

An “insightful” and in-depth look at anti-science politics and its deadly results (Maria Konnikova, New York Times–bestselling author of The Biggest Bluff). Thomas Jefferson said, “Wherever the people are well informed, they can be trusted with their own government.” But what happens when they aren’t? From climate change to vaccinations, transportation to technology, health care to defense, we are in the midst of an unprecedented expansion of scientific progress—and a simultaneous expansion of danger. At the very time we need them (...) most, scientists and the very idea of objective knowledge are being bombarded by a vast, well-funded war on science, and the results are deadly. Whether it’s driven by identity politics, ideology, or industry, the result is an unprecedented erosion of thought in Western democracies as voters, policymakers, and justices actively ignore scientific evidence, leaving major policy decisions to be based more on the demands of the most strident voices. This compelling book investigates the historical, social, philosophical, political, and emotional reasons why evidence-based politics are in decline and authoritarian politics are once again on the rise on both left and right—and provides some compelling solutions to bring us to our collective senses, before it's too late. “If you care about attacks on climate science and the rise of authoritarianism, if you care about biased media coverage and shake-your-head political tomfoolery, this book is for you.”—The Guardian.

The operational semantics of Urquhart is a deep and important part of the development of relevant logics. In this paper, I present an overview of work on Urquhart’s operational semantics. I then present the basics of collection frames. Finally, I show how one kind of collection frame, namely, functional set frames, is equivalent to Urquhart’s semilattice semantics.

This interdisciplinary analysis presents an innovative examination of the nature of pride and humility, including all their slippery nuances and points of connection. By combining insights from visual art, literature, philosophy, religious studies, and psychology, this volume adapts a complementary rather than an oppositional approach to examine how pride and humility reinforce and inform one another. This method produces a robust, substantial, and meaningful description of these important concepts. The analysis takes into account key elements of pride and humility, including (...) self-esteem and self-confidence, human interconnectedness, power's function and limitations, and the role of fear. Shawn R. Tucker explores the many inflections of these terms, inflections that cast them by turns as positive or negative, emboldening or discouraging, and salubrious or vicious depending upon the context and manner in which they are used.

Aquinas claims that sacred doctrine is a science, or scientia. All scientiae involve demonstrations containing principles which yield conclusions that are necessary and certain. The principles leading to sacred scientia are the articles of faith. Those articles are contained in Scripture and constitute the premises of demonstrations the conclusions of which form sacred doctrine's content. Because of those articles' divine origin, we can expect them to yield conclusions the truth of which is guaranteed. According to William Abraham, however, Aquinas must (...) demonstrate Scripture's divine origin as a condition for achieving a sacred scientia. In the absence of such a demonstration, we cannot be certain that the articles contained in Scripture are God‐breathed, nor can we be certain that the conclusions deduced from them belong to sacred doctrine. Abraham argues that Aquinas's putative demonstration of Scripture's divine origin fails and—consequently—so does his attempt to establish a sacred scientia. In this paper, I will show that Aquinas never intended to provide such a demonstration, nor does he need to in order to secure sacred doctrine's status as a scientia. Furthermore, I will show that achieving sacred scientia is not, pace Abraham, an epistemological undertaking but a spiritual discipline that eventuates in knowledge of and love for God. (shrink)

Anderson and Belnap presented indexed Fitch-style natural deduction systems for the relevant logics R, E, and T. This work was extended by Brady to cover a range of relevant logics. In this paper I present indexed tree natural deduction systems for the Anderson–Belnap–Brady systems and show how to translate proofs in one format into proofs in the other, which establishes the adequacy of the tree systems.

Circular denitions have primarily been studied in revision theory in the classical scheme. I present systems of circular denitions in the Strong Kleene and supervaluation schemes and provide complete proof systems for them. One class of denitions, the intrinsic denitions, naturally arises in both schemes. I survey some of the features of this class of denitions.

In this paper, an incompleteness theorem for modal extensions of relevant logics is proved. The proof uses elementary methods and builds upon the work of Fuhrmann.
