I argue that, contrary to how he is often read, Spinoza did not believe that the mind and the body were numerically identical. This means that we must find some alternative reading for his claims that they are 'one and the same thing'.

According to the logical pluralism of Beall and Restall, there are several distinct relations of logical consequence. Some critics argue that logical pluralism suffers from what I call the collapse problem: that despite its intention to articulate a radically pluralistic doctrine about logic, the view unintentionally collapses into logical monism. In this paper, I propose a contextualist resolution of the collapse problem. This clarifies the mechanism responsible for a plurality of logics and handles the motivating data better than the original (...) view. It is a major improvement that should be embraced by all logical pluralists. (shrink)

This paper is about the underlying logical principles of scientific theories. In particular, it concerns ex contradictione quodlibet (ECQ) the principle that anything follows from a contradiction. ECQ is valid according to classical logic, but invalid according to paraconsistent logics. Some advocates of paraconsistency claim that there are ‘real’ inconsistent theories that do not erupt with completely indiscriminate, absurd commitments. They take this as evidence in favor of paraconsistency. Michael (2016) calls this the non-triviality strategy (NTS). He argues that this (...) strategy fails in its purpose. I will show that Michael's criticism significantly over-reaches. The fundamental problem is that he places more of a burden on the advocate of paraconsistency than on the advocate of classical logic. The weaknesses in Michael's argument are symptomatic of this preferential treatment of one viewpoint in the debate over another. He does, however, make important observations that allow us to clarify some of the complexities involved in giving a logical reconstruction of a theory. I will argue that there are abductive arguments deserving of further consideration for the claim that paraconsistent logic offers the best explanation of the practice of inconsistent science. In this sense, the debate is still very much open. (shrink)

This paper scrutinizes the debate over logical pluralism. I hope to make this debate more tractable by addressing the question of motivating data: what would count as strong evidence in favor of logical pluralism? Any research program should be able to answer this question, but when faced with this task, many logical pluralists fall back on brute intuitions. This sets logical pluralism on a weak foundation and makes it seem as if nothing pressing is at stake in the debate. The (...) present paper aims to improve this situation by looking at a promising case study and drawing general lessons about the kind of evidence that would support logical pluralism. I argue that the best motivation for logical pluralism will ultimately be rooted in certain kinds of performative data. (shrink)

Logical consequence is the relation that obtains between premises and conclusion(s) in a valid argument. Orthodoxy has it that valid arguments are necessarily truth-preserving, but this platitude only raises a number of further questions, such as: how does the truth of premises guarantee the truth of a conclusion, and what constraints does validity impose on rational belief? This volume presents thirteen essays by some of the most important scholars in the field of philosophical logic. The essays offer ground-breaking new insights (...) into the nature of logical consequence; the relation between logic and inference; how the semantics and pragmatics of natural language bear on logic; the relativity of logic; and the structural properties of the consequence relation.

Agroecology has been proposed as a key building block for food sovereignty. This article examines the meaning, practices and potentials of ‘transformative agroecology learning’ as a collective strategy for food system transformation. Our study is based on our qualitative and action research with the European Coordination of Via Campesina to develop the European Agroecology Knowledge Exchange Network. This network is linked to the global network of La Via Campesina and builds on the strong experiences and traditions of popular education in (...) Latin American peasant movements. Rather than focusing on agroecology education as a process of individual learning, we analyse how a transformative agroecology education can be strengthened as a critical repertoire of action used by social movements to advance food sovereignty. Our analysis contributes a new theory of transformative agroecology learning based on four key characteristics or qualities: horizontalism; diálogo de saberes ; combining practical and political knowledge; and building social movement networks. While these different elements of transformative agroecology learning were present across EAKEN, they were unevenly developed and, in many cases, not systematized. The framework can help to strategically and reflexively systematize and strengthen a transformative agroecology learning approach as a key building block for food sovereignty. (shrink)

According to Jago (2014a), logical omniscience is really part of a deeper paradox. Jago develops an epistemic logic with principles of indeterminate closure to solve this paradox, but his official semantics is difficult to navigate, it is motivated in part by substantive metaphysics, and the logic is not axiomatized. In this paper, I simplify this epistemic logic by adapting the hyperintensional semantic framework of Sedlár (2021). My first goal is metaphysical neutrality. The solution to the epistemic paradox should not require (...) appeal to a metaphysics of truth-makers, situations, or impossible worlds, by contrast with Jago’s official semantics. My second goal is to elaborate on the proof theory. I show how to axiomatize a family of logics with principles of indeterminate epistemic closure. (shrink)

This note motivates a logic for a theory that can express its own notion of logical consequence—a ‘syntactically closed’ theory of naive validity. The main issue for such a logic is Curry’s paradox, which is averted by the failure of contraction. The logic features two related, but different, implication connectives. A Hilbert system is proposed that is complete and non-trivial.

In a recent series of articles, Beall has developed the view that FDE is the formal system most deserving of the honorific “Logic”. The Simple Argument for this view is a cost-benefit analysis: the view that FDE is Logic has no drawbacks and it has some benefits when compared with any of its rivals. In this paper, I argue that both premises of the Simple Argument are mistaken. I use this as an opportunity to further reflect on how such arguments (...) can be bolstered to provide more substantial and productive support for revisionary theses about Logic. (shrink)

Recent work in philosophical logic has taken interesting and unexpected turns. It has seen not only a proliferation of logical systems, but new applications of a wide range of different formal theories to philosophical questions. As a result, philosophers have been forced to revisit the nature and foundation of core logical concepts, chief amongst which is the concept of logical consequence. This essay sets the contributions of the volume in context and identifies how they advance important debates within the philosophy (...) of logic. (shrink)

During development of the Xenopus embryo, the formation of the nervous system depends on an inductive interaction between mesoderm and ectoderm. The result is a neural tube that is regionally differentiated along the anterior–posterior axis from forebrain to spinal cord (Fig. 1). The discovery of genes whose transcripts can be used as molecular markers for different regions of the nervous system has permitted reassessment of the existing theories of neural tissue formation. Although the neural inducing molecules remain elusive, the mechanism (...) by which cells interact to form a regionally differentiated nervous system is becoming clearer. (shrink)

While evidence for the role of gap functions, particularly during development, has been mounting, it has remained largely correlative, linking structure with presumed functions. With the recent advent of functional antibodies raised to the junctional protein, however, it has become possible to study the role of gap junctions more directly. There is now considerable evidence indicating that they play a vital role in tissue pattern formation and differentiation by allowing direct cell‐to‐cell transfer of developmental signals or morphogens.

The advocate of modal logic or relevant logic has traditionally argued that her preferred system offers the best regimentation of the theory of entailment. Essential to the projects of modal and relevant logic is the importation of non-truth-functional expressive resources into the object language on which the logic is defined. The most elegant technique for giving the semantics of such languages is that of frame semantics, a variation on which features the device of partitioned frames that divide 'points of evaluation' (...) into two types: normal points and abnormal points. This essay attempts to provide satisfying philosophical interpretations of the partitioned frame semantics for some weak modal logics and relevant logics. According to the current best interpretation, partitioned frame semantics are a kind of possible worlds semantics that appeal to 'logically impossible worlds' where the laws of logic may fail to hold. This is undermined by the fact that all of the target logics fail to satisfy criteria of expressibility needed to support the thesis that laws of logic fail to hold at abnormal points. This suggests that we should not look for a monistic interpretive paradigm for partitioned frame semantics. (shrink)

Local sustainable food systems have captured the popular imagination as a progressive, if not radical, pillar of a sustainable food future. Yet these grassroots innovations are embedded in a dominant food regime that reflects productivist, industrial, and neoliberal policies and institutions. Understanding the relationship between these emerging grassroots efforts and the dominant food regime is of central importance in any transition to a more sustainable food system. In this study, we examine the encounters of direct farm marketers with food safety (...) regulations and other government policies and the role of this interface in shaping the potential of local food in a wider transition to sustainable agri-food systems. This mixed methods research involved interview and survey data with farmers and ranchers in both the USA and Canada and an in-depth case study in the province of Manitoba. We identified four distinct types of interactions between government and farmers: containing, coopting, contesting, and collaborating. The inconsistent enforcement of food safety regulations is found to contain progressive efforts to change food systems. While government support programs for local food were helpful in some regards, they were often considered to be inadequate or inappropriate and thus served to coopt discourse and practice by primarily supporting initiatives that conform to more mainstream approaches. Farmers and other grassroots actors contested these food safety regulations and inadequate government support programs through both individual and collective action. Finally, farmers found ways to collaborate with governments to work towards mutually defined solutions. While containing and coopting reflect technologies of governmentality that reinforce the status quo, both collaborating and contesting reflect opportunities to affect or even transform the dominant regime by engaging in alternative economic activities as part of the ‘politics of possibility’. Developing a better understanding of the nature of these interactions will help grassroots movements to create effective strategies for achieving more sustainable and just food systems. (shrink)

The semantic tradition in logic descends from Tarski's seminal work on truth and logical consequence. In the introduction to this volume, Sagi and Woods remind us that this tradition prominently uses model theory to study languages and their interpretations. Tarski's model-theoretic definition of logical consequence is the prime example of this approach, seeking as it does to reduce logical properties to a class of operations on classical, iterative (ZF) sets. Sagi and Woods explain with admirable clarity the origins, implications, and (...) philosophical questions surrounding this project. The contributions to the volume go on to address whether this approach successfully elucidates logicality and how it intersects with the foundations of mathematics and natural language semantics.

Most writing on informed consent in Africa highlights different cultural and social attributes that influence informed consent practices, especially in research settings. This review presents a composite picture of informed consent in Nigeria using empirical studies and legal and regulatory prescriptions, as well as clinical experience. It shows that Nigeria, like most other nations in Africa, is a mixture of sociocultural entities, and, notwithstanding the multitude of factors affecting it, informed consent is evolving along a purely Western model. Empirical studies (...) show that 70–95% of Nigerian patients report giving consent for their surgical treatments. Regulatory prescriptions and adjudicated cases in Nigeria follow the Western model of informed consent. However, adversarial legal proceedings, for a multiplicity of reasons, do not play significant roles in enforcing good medical practice in Nigeria. Gender prejudices are evident, but not a norm. Individual autonomy is recognized even when decisions are made within the family. Consent practices are influenced by the level of education, extended family system, urbanization, religious practices, and health care financing options available. All limitations notwithstanding, consent discussions improved with increasing level of education of the patients, suggesting that improved physician's knowledge and increasing awareness and education of patients can override other influences. Nigerian medical schools should restructure their teaching of medical ethics to improve the knowledge and practices of physicians. More research is needed on the preferences of the Nigerian people regarding informed consent so as to adequately train physicians and positively influence physicians' behaviors. (shrink)

The patient wished to receive an experimental drug that she was instrumental in developing. After her diagnosis, she had investigated treatments that might help her condition and discovered that a specific compound could be beneficial. To further the development of this potential drug, she obtained preclinical data, founded a company, and sought investment from venture capitalists. The company was about to begin phase I testing, but the clinical trial had not yet opened. In addition, she would not have been a (...) candidate for the study, as it excluded patients with advanced disease. To be able to administer this drug to her, the patient's team of oncologists was in the process of drafting an individual patient investigational new drug application, including the protocol for the drug's delivery, to the Food and Drug Administration. The company developing the drug had preliminarily agreed to provide it. This protocol was also under review by the institutional review board of the university, and the ethics committee was consulted to determine whether she should receive the drug. (shrink)

This is a study involving three HIV clinics in the Canadian provinces of Newfoundland and Labrador, and Manitoba. We sought to identify ethical issues involving health care providers and clinic clients in these settings, and to gain an understanding of how different ethical issues are managed by these groups. We used an institutional ethnographic method to investigate ethical issues in HIV clinics. Our researcher conducted in-depth semi-structured interviews, compiled participant observation notes, and studied health records in order to document ethical (...) issues in the clinics, and to understand how health care providers and clinic clients manage and resolve these issues. We found that health care providers and clinic clients have developed work processes for managing ethical issues of various types: conflicts between client-autonomy and public health priorities, difficulties associated with the criminalization of nondisclosure of HIV positive status, challenges with non-adherence to HIV treatment, the protection of confidentiality, barriers to treatment access, and negative social determinants of health and well-being. Some ethical issues resulted from structural disadvantages experienced by clinic clients. The most striking findings in our study were the negative social determinants of health and well-being experienced by some clinic clients – such as experiences of violence and trauma, poverty, racism, colonization, homelessness, and other factors affecting well-being such as problematic substance use. These negative determinants were at the root of other ethical issues, and are themselves of ethical concern. (shrink)

This chapter analyzes several key themes in Kant’s views about modality. We begin with the pre-critical Only Possible Argument in Support of a Demonstration of the Existence of God, in which Kant distinguishes between formal and material elements of possibility, claims that all possibility requires an actual ground, and argues for the existence of a single necessary being. We then briefly consider how Kant’s views change in his mature period, especially concerning the role of form and thought in defining modality. (...) Kant’s mature views, however, present two difficult interpretive puzzles. The first puzzle concerns whether Kant has a generally reductive view of modality. While Kant’s views on logical modality, the role of actuality in grounding possibility, and the relation of modality to cognition all suggest reduction, we argue that the categorial status of modal concepts and the difficulty in even identifying amodal grounds for modal facts all suggest a non-reductive view. The second puzzle concerns whether Kant accepts modal facts or properties at the noumenal level. While Kant’s appeal to noumenal necessary connections, the contingency of noumenal willing, and the idea of a necessary noumenal being suggest that he endorses noumenal modality, his claims that modal concepts express only relations to the faculty of cognition and his claim that modal concepts arise from our distinctive psychological structures, we argue, suggest that he rejects noumenal modality. We conclude by considering potential solutions to these puzzles. (shrink)

Schopenhauer repeatedly claims that suicide is both foolish and futile. But while many commentators have expressed sympathy for his charge of foolishness, most regard his charge of futility as indefensible even within his own system. In this paper, I offer a defense of Schopenhauer’s futility charge, based on metaphysical and psychological considerations. On the metaphysical front, Schopenhauer’s view implies that psychological connections extend beyond death. Drawing on Parfit’s discussion of personal identity, I argue that those connections have personal significance, such (...) that suicide does not allow one, as Hamlet hopes, simply “not to be.” On the psychological front, I argue that a distinction between agents’ intentions and underlying desires makes room for Schopenhauer to claim that paradigmatic suicidal agents ultimately desire the opposite of what suicide accomplishes. I conclude by showing how the resulting account of futility can buttress the charge of foolishness as well. My interpretation still leaves Schopenhauer vulnerable to certain objections, but shows that his account is significantly more defensible than previous commentators have realized. (shrink)

Political persuasion can express moral respect. In this article, however, I rely on two psychological assumptions to argue that political persuasion is generally prima facie disrespectful: (1) that we maintain our political beliefs largely for non-epistemic, personal reasons and (2) that our political beliefs are connected to our epistemic esteem. Given those assumptions, a persuader can either ignore the relevant personal reasons, explicitly address them, or implicitly address them. Ignoring those reasons, I argue, constitutes prima facie insensitivity. Explicitly addressing them (...) constitutes a form of prima facie incivility. Finally, implicitly addressing them covertly treats those personal reasons as psychological puppet strings, constituting prima facie objectionable manipulation. This prima facie insensitivity, incivility, and manipulation are each prima facie failures of respect, either for the persuadee’s rationality or for their agency. Political persuasion can sometimes be all-things-considered justified, but these moral hazards can produce reasonable guilt, resentment, and blowback. (shrink)

On the traditional reading, Schopenhauer claims that compassion is the recognition of deep metaphysical unity. In this paper, I defend and develop the traditional reading. I begin by addressing three recent criticisms of that reading from Sandra Shapshay: that it fails to accommodate Schopenhauer's restriction to sentient beings, that it cannot explain his moral ranking of egoism over malice, and that Schopenhauer requires some level of distinction to remain in compassion. Against Shapshay, I argue that Schopenhauer does not restrict compassion (...) to sentient beings and that a more metaphysically refined version of the traditional reading can accommodate both Schopenhauer's moral ranking of characters and allow for some level of distinction in compassion. I then turn to four further questions for the traditional reading: what the relation is between the feeling of compassionate pain and the recognition of metaphysical unity, how cognitions mediate compassion, whether compassion is limited to the present, and how the feeling of compassion relates to Schopenhauer's fundamental moral principle. I conclude by explaining how, in a reductive vein, the traditional reading can also allow for compassion to have normative content. (shrink)

This book offers a ground-up defense of objective morality, drawing inspiration from a wide range of philosophers, including John Locke, Arthur Schopenhauer, Iris Murdoch, Nel Noddings, and David Lewis. The core claim is compassion is our capacity to perceive other creatures' pains, pleasures, and desires. Non-compassionate people are therefore perceptually lacking, regardless of how much factual knowledge they might have. Marshall argues that people who do have this form of compassion thereby fit a familiar paradigm of moral goodness. His (...) argument involves the identification of an epistemic good which Marshall dubs "being in touch". To be in touch with some property of a thing requires experiencing it in a way that reveals that property - that is, experiencing it as it is in itself. Only compassion, Marshall argues, lets us be in touch with others' motivational mental properties. -/- This conclusion about compassion has two important metaethical consequences. First, it generates an answer to the question ";Why be moral?", which has been a central philosophical concern since Plato. Second, it provides the keystone for a novel form of moral realism. This form of moral realism has a distinctive set of virtues: it is anti-relativist, naturalist, and able to identify a necessary connection between moral representation and motivation. The view also implies that there is an epistemic asymmetry between virtuous and vicious agents, according to which only morally good people can fully face reality. (shrink)

Kant's philosophy promises to explain various synthetic a priori claims. Yet, as several of his commentators have noted, it is hard to see how these explanations could work unless they themselves rested on unexplained synthetic a priori claims. Since Kant appears to demand explanations for all synthetic a priori claims, it would seem that his project fails on its own terms. I argue, however, that Kant holds that explanations are required only for synthetic a priori claims about (purportedly) experience-independent entities, (...) and that his project rests on a rationalist method of reflection that justifies certain basic synthetic a priori claims.

Wynn's claims are, in principle, entirely reasonable; although, as always, the devil is in the details. With respect to Wynn's discussion of the cultural evolution of artifactual symmetry, we provide a few more arguments for the utility of mirror symmetry and extend the enquiry into the tacit and explicit processing of natural and artifactual symmetry.

Robustly realistic metaphysical readings of Kant’s mature views have become popular in recent years, largely because of the apparent coherence of applying unschematized categories like that of causation to things in themselves. There is, however, an overlooked problem that arises even for robust realist readings that privilege unschematized categories. The problem is that Kant provides all the elements for what is now called a ‘debunking explanation’ of metaphysical representations of things in themselves. His account of the categories as arising from (...) mere forms of judgment, and being applied primarily for the unity of consciousness, is detached from the issue of whether there are causes among things in themselves. This detachment seems to imply that it would be a huge coincidence if unschematized categories corresponded to any such causes. After making this argument, using the category of causation as my central case, I consider three potential responses: that Kant’s account implicitly appeals to things in themselves’ causation, that Kant has a separate account of non-coincidental representation, and that Kant’s account is merely incomplete in a way that poses no debunking threat. None of these responses, I argue, are successful, so I conclude that either robustly realistic metaphysical readings are mistaken, or there is internal incoherence in Kant’s views. (shrink)

Spinoza claims we can control any passion by forming a more clear and distinct idea of it. The interpretive consensus is that Spinoza is either wrong or over-stating his view. I argue that Spinoza’s view is plausible and insightful. After breaking down Spinoza’s characterization of the relevant act, I consider four existing interpretations and conclude that each is unsatisfactory. I then consider a further problem for Spinoza: how his definitions of ‘action’ and ‘passion’ make room for passions becoming action. I (...) propose two solutions to this problem, both of which yield a hint regarding what act Spinoza has in mind. Using that hint, I propose that we can appreciate Spinoza’s insight by considering how philosophizing about a feeling can 'kill the mood.' The act of grasping how a passion exemplifies certain general truths, I hold, is a distinctly rational activity that has all the features Spinoza describes. I conclude by showing how this interpretation fits with Spinoza’s larger views on rational knowledge, rational joy, the comprehensibility of passions, and the relation between second- and first-order ideas. (shrink)

I argue that Spinoza is more of a moral realist than an anti-realist. More specifically, I argue that Spinoza is more of a realist than Kant, and that his view has deep similarities with Plato's metaethics. Along the way, I identify three approaches to the moral realism/anti-realism distinction. Classifying Spinoza as a moral realist brings out a number of important complexities that have been overlooked by many of Spinoza's readers and by many contemporary metaethicists.

The one-world interpretation of Kant's idealism holds that appearances and things in themselves are, in some sense, the same things. Yet this reading faces a number of problems, all arising from the different features Kant seems to assign to appearances and things in themselves. I propose a new way of understanding the appearance/thing in itself distinction via an Aristotelian notion that I call, following Kit Fine, a ‘qua-object.’ Understanding appearances and things in themselves as qua-objects provides a clear sense in (...) which they can be the same things while differing in many of their features.
