Justification logics provide frameworks for studying the fine structure of evidence and justification. Traditionally, these logics do not impose any closure requirements on justification. In this paper, we argue that for some applications they should subject justification to closure under some variety of logical consequence. Specifically, we argue, building on ideas from Beall, that the non-classical logic FDE offers a particularly attractive notion of consequence for this purpose and define a justification logic where justification is closed under FDE consequence. We (...) show the resulting logic to be sound and complete. Lastly, we discuss how the closure of justification under FDE ontrasts closure under related non-classical logics and how our approach contrasts with some alternatives. (shrink)

Various theorists have endorsed the “communication argument”: communicative capacities are necessary for morally responsible agency because blame aims at a distinctive kind of moral communication. I contend that existing versions of the argument, including those defended by Gary Watson and Coleen Macnamara, face a pluralist challenge: they do not seem to sit well with the plausible view that blame has multiple aims. I then examine three possible rejoinders to the challenge, suggesting that a context-specific, function-based approach constitutes the most promising (...) modification of the communication argument.

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)

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.

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.

It is widely agreed that reactive attitudes play a central role in our practices concerned with holding people responsible. However, it remains controversial which emotional attitudes count as reactive attitudes such that they are eligible for this central role. Specifically, though theorists near universally agree that guilt is a reactive attitude, they are much more hesitant on whether to also include shame. This paper presents novel arguments for the view that shame is a reactive attitude. The arguments also support the (...) view that shame is a reactive attitude in the sense that concerns moral accountability. The discussion thereby challenges both the view that shame is not a reactive attitude at all, suggested by philosophers such as R. Jay Wallace and Stephen Darwall, and the view that shame is a reactive attitude but does not concern moral accountability, recently defended by Andreas Carlsson and Douglas Portmore. (shrink)

BackgroundRecent advancements in neuroscientific techniques have allowed us to make huge progress in our understanding of memories, and in turn has paved the way for new memory modification technologies that can modulate memories with a degree of precision, which was not previously possible. With advancements in such techniques, new and critical ethical questions have emerged. Understanding and framing these ethical questions within the current philosophical theories is crucial in order to systematically examine them as we translate these techniques to the (...) clinic.Main bodyIn this paper, we discuss the ethical implications of modern neuroscience techniques that aim to disrupt or enhance memories. We attempt to frame the MMTs in the context of existing ethical philosophical theories to provide a cohesive analysis of the myriad of ethical quagmires that might emerge from such technologies. We argue the application of Aristotle’s Golden Mean and multiple accounts of authenticity are useful in approaching the ethical questions surrounding MMTs. We then propose a framework in which ethical considerations can be systematically examined. Lastly, we provide caveats and considerations for the use of this framework. Overall, we provide a practical approach for the ethical use of MMTs depending on the situation.ConclusionWhile at face value, our model appears to put severe limitations on the application of MMTs, we are not completely opposed to their use, but rather our framework guides the agent to consider the implications before making any decisions. Most importantly, we argue that the use of MMTs does not reduce the responsibility of the initial decision, and the agent must accept the post-MMT self as the new “true self” regardless of the outcome. As the developmental trajectory of MMTs suggests we are getting closer to practical clinical applications, ethical concerns across a wide range of disciplines need to be addressed to develop best strategies and policies when dealing with MMTs. If this can be achieved, we believe the ethical use of MMTs is not only possible but would also be of tremendous benefit to many people suffering from memory-related mental disorders. (shrink)

As local food activities expand and grow, an important question to answer is how various participants contribute to a local food system’s overall vitality and strength. This paper does so by focusing on the relationships between locally-oriented farm and retail actors and assessing what the configuration of these relationships tells us about the workings of the broader local food system. Such an analysis reveals two things. Empirically, it shows the important role food retailers play in the overall vibrancy of local (...) food exchanges: food retailers form crucial links holding the broader system together and significantly expanding consumer access to local foods. Further, different retailer types have distinct impacts on network configurations, each serving particular roles in the development and maintenance of local food systems. Methodologically, this paper shows the value of applying social network analysis techniques to the study of local food systems: such an approach yields insights that may not be as readily assessable from other strategies. In this paper, I overview common network analysis techniques and apply them to a case study of local food activities in New England, suggesting how such an approach might be applied to local food systems in other places.

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)

In this article, we present a definition of a hyperintensionality appropriate to relevant logics. We then show that relevant logics are hyperintensional in this sense, drawing consequences for other non-classical logics, including HYPE and some substructural logics. We further prove results concerning extensionality in relevant logics. We close by discussing related concepts for classifying formula contexts and potential applications of these results.

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)

This argument explores transcultural commonalities among civic arguments from divination in global antiquity. In the ancient world, proponents engaged in kisceral arguments deriving from divinatory signs: arguments ex divinatione regarding prospective civic action. Under ideal circumstances, their aim was to help insure that the collective action of human political organizations was aligned with the natural synchrony of the cosmos. Thus, civic arguments from divination were employed to anticipate the future’s course based on the signs the system produced holistically. In ancient (...) Mesopotamia, China, and Rome, divination was employed as a tool for aligning the order of human society to that of a conception of metaphysical or cosmic order. By comparing these argumentative examples and rationales, we see a broader context for the way in which humans made arguments toward political futurity outside more conventional syllogistic formulations concerning causation. Rather, the argumentative strategies of many ancient cultures embraced an understanding of the future as the logical outcome of a holistic dynamism in kairotic time. (shrink)

A common refrain in and outside academia is that prominent sports figures ought to engage more in the public discourse about political issues. This idea parallels the idea that athletes ought to be role models in general. This paper first examines and critiques the “athlete as role model” argument and then applies this critique to the “athlete as political activist” argument. Appealing to the empirical political psychological literature, the paper sketches an argument that athlete activism might actually do more harm (...) than good. (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)

Few debates in environmental philosophy have been more heated than the one over the nature of wilderness. And yet, when one surveys the present scene, one finds that a variety of different conceptions of wilderness are still quite popular – some more so in certain professions than others. In this paper, I look at three popular conceptions of wilderness with an eye toward sussing out the good and the bad them. I look at what I call (1) the folk view (...) of wilderness, (2) Leopold’s conception of wilderness, and (3) the legal conception of wilderness (as found in the Wilderness Act of 1964). In the final part of the paper, I sketch out a sort of spectrum account of wilderness, one that I argue allows us to capture more cases of wilderness and might serve as a useful tool in future conservation efforts.

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.

Environmental philosophy plays an important role, directly and indirectly, in many parts of society, including land and wildlife management (Leopold, 1949; Minteer, 2015), political activism (Abbey, 1968; Malm, 2020),and technological research and development (Baum & Owe, 2022; Donhauser et al., 2021). Environmental philosophy uncovers the ethical relationships existing between humans and the living and non-living world. It reveals the nuances of our scientific ecological concepts. And it tries to tell us how we might act – individually or collectively – to (...) better achieve our environmental goals. The aim of this special issue is to explore the limits and ever-expanding outer edges of this increasingly important area of philosophical thought. (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.

When asked which of our concepts are normative concepts, metaethicists would be quick to list such concepts as GOOD, OUGHT, and REASON. When asked why such concepts belong on the list, metaethicists would be much slower to respond. Matti Eklund is a notable exception. In his recent book, Choosing Normative Concepts, Eklund argues by elimination for “the Normative Role view” that normative concepts are normative in virtue of having a “normative role” or being “used normatively”. One view that Eklund aims (...) to eliminate is “the Metaphysical view” that normative concepts are normative in virtue of referring to normative properties. In addition to arguing that Eklund’s objection looks doubtful by its own lights, we argue that there are several plausible versions of the Metaphysical view that Eklund doesn’t eliminate, defending various claims about normative concepts and their relationships to deliberation, competence, reference, and possession along the way.

In relevant logics, necessary truths need not imply each other. In justification logic, necessary truths need not all be justified by the same reason. There is an affinity to these two approaches that suggests their pairing will provide good logics for tracking reasons in a fine-grained way. In this paper, I will show how to extend relevant logics with some of the basic operators of justification logic in order to track justifications or reasons. I will define and study three kinds (...) of frames for these logics. For the first kind of frame, I show soundness and highlight a difficulty in proving completeness. This motivates two alternative kinds of frames, with respect to which completeness results are obtained. Axioms to strengthen the justification logic portions of these logics are considered. I close by developing an analogy between the dot operator of justification logic and theory fusion in relevant logics. (shrink)

Various cell types cooperate to create a highly organized and dynamic micro-environmental niche in the bone marrow. Over the past several years, the field has increasingly recognized the critical roles of the interplay between bone marrow environment and hematopoietic cells in normal and deranged hematopoiesis. These advances rely on several new technologies that have allowed us to characterize the identity and roles of these niches in great detail. Here, we review the progress of the last several years, list some of (...) the outstanding questions in the field and propose ways to target the diseased environment to better treat hematologic diseases. Understanding the extrinsic regulation by the niche will help boost hematopoiesis for regenerative medicine. Based on natural development of hematologic malignancies, we propose that combinatory targeting the niche and hematopoietic intrinsic mechanisms in early stages of hematopoietic malignancies may help eliminate minimal residual disease and have the highest efficacy. The bone marrow is the home for blood-forming hematopoietic stem and progenitor cells. Normal generation of blood and immune cells depends on highly regulated interactions between these stem and progenitor cells with their surrounding environment. Emerging evidence suggests that therapeutic interventions directed at these cellular interdependencies can help boost hematopoiesis and eradicate malignant hematopoietic cells. (shrink)

Attention to care in modern society has fallen out of view as an ethos of personal responsibility, free markets, and individualism has been in the ascendant. The Liberalism of Care argues that contemporary liberalism is suffering from a crisis of care, manifest in a decaying sense of collective political responsibility for citizens' well- being and for the most vulnerable members of our communities. The book maintains that this practical crisis stems from a theoretical one. We have lost the political language (...) of care, which, prior the 19th century, was commonly used to express these dimensions of political life. To recover that language, Shawn C. Fraistat turns to three prominent philosophers-Plato, Jean-Jacques Rousseau, and William Godwin-who illuminate the varied ways caring language and caring values have structured core debates in the history of Western political thought about the proper role of government, as well as the rights and responsibilities of citizens. The Liberalism of Care presents a distinctive vision for our liberal politics where political communities and citizens can utilize the ethic and practices of care to face practical challenges.

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)

While traditionally Plato has been read as a critic of democracy and an advocate of philosopher-kingship, a number of more recent interpretations have argued that Plato’s views about these issues changed over the course of his life. Several scholars argue that Plato shifts from an authoritarian outlook in “middle period” dialogues, such as the Republic, to a more democratic view in “late” dialogues, such as the Laws. In contrast to these scholars, this article argues that Plato’s attitude towards authority and (...) democracy is consistent in his “middle” and “late” periods. I show that Plato defines law as the writing of political experts, and that the Laws turns to written law as a second-best method for instituting the rule of the wise. This interpretation enables us to understand the Laws as a dialogue about the political use of writing, which helps illuminate some of the more peculiar features of the Laws and account for its place in the Platonic corpus.

Classical Liberalism is a view that the only justifiable restraints on the actions and choices of individuals in political orders are ones necessary to preserve individual liberty. Central to this view of liberty is the individual being left free from coercive interference from other individuals and society as a whole. This view presumes the idea that the individual is, firstly, able to choose his ends and actions, and secondly, that the individual is the best judge of these. Thus, the individualism (...) of classical liberalism presupposes a view of human consciousness that is volitional: capable of engaging in choice and individual self-direction. If this view of human consciousness is in conflict with the physical casual and evolutionary accounts of the world, then classical liberalism would seem to have serious problem. Therefore, I argue that the correct conception of volitional consciousness is consistent with the physical causal and evolutionary accounts of the world. Presenting a conception of volitional consciousness that makes the best sense of our introspective experience and knowledge of the world, I then show how such a volitional consciousness is consistent with causality and biological evolution.

What did science make possible for colonial rule? How was science in turn marked by the knowledge and practices of those under colonial rule? Here I approach these questions via the social history of Madras Observatory. Constructed in 1791 by the East India Company, the observatory was to provide local time to mariners and served as a clearinghouse for the company’s survey and revenue administration. The astronomical work of Madras’ Brahmin assistants relied upon their knowledge of jyotiśāstra [Sanskrit astronomy/astrology], and (...) can be seen as a specialized form of the kind of South Indian scribal labor and knowledge that also staffed the company’s tax offices. If at Greenwich the division of labor meant observatory work bore resemblances to the factory and the accounts office, in Madras, astronomy and accounting drew on similar labor forms because they were part of the same enterprise. But the company did not just adapt preexisting forms of labor, it also attempted to produce its own at a school built near the observatory to train “half-caste” orphans as apprentice surveyors and assistant computers. The school, staffed by the Brahmins, drew upon knowledge and pedagogical practice associated with the tinnai, the schools in which upper-caste children learned to read, write, and calculate. For a time, the observatory’s social order was literally “half-caste.” The paper also considers how the relationship between caste, status, and instrument was reflected in the visual and material culture of the observatory, such as in Indian-language inscriptions on its central pillar. For company astronomers, the measurement of time meant reworking the relationships among the Indian past, the colonial present, and an imperial posterity. Science under colonial rule spanned multiple temporal and social registers because it was the result of negotiations between the demands of political economy and the knowledge and practices of colonized others.

The contribution of this work is a classification of corporate social action underlying the Social Ratings Data compiled by Kinder Lydenburg Domini Analytics, Inc. We compare extant typologies of corporate social action to the results of our exploratory factor analysis.

Akey finding of our research is that positive and negative social action are both empirically and conceptually distinct constructs and should not be combined in (...) future research. Additionally, we recommend that some prior research results be reconsidered to determine whether these newly derived measures might clarify some previous findings. (shrink)

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.
