How does microbiota research impact our understanding of biological individuality? We summarize the interdisciplinary summer school on "Microbiota, Symbiosis and Individuality: Conceptual and Philosophical Issues" (July 2019), which was supported by a European Research Council starting grant project "Immunity, DEvelopment, and the Microbiota" (IDEM). The summer school centered around interdisciplinary group work on four facets of microbiota research: holobionts, individuality, causation, and human health. The conceptual discussion of cutting-edge empirical research provided new insights into microbiota and highlights the value of (...) incorporating into meetings experts from other disciplines, such as philosophy and history of science.

In this paper I argue against two prevailing views of Kant’s Religion. Against commentators such as Michalson and Quinn, who have argued that Kant’s project in Religion is riddled with inconsistencies and circularities, I show that a proper understanding of Kant’s views on grace reveals these do not exist. And contra commentators that attribute to Kant at best a minimalist conception of grace, I show that Kant’s view of it is remarkably robust. I argue that Kant works with three different (...) conceptions of grace. These are: a) grace and the God within, b) grace and the transformation of the fundamental orientation, and c) grace that can be laid hold of; the first and the last play a significant role in his philosophy of religion.

It is common to think that we would be morally better people if we never felt envy. Recently, some philosophers have rejected this conclusion by arguing that envy can often be directed toward unfairness or inequality. As such, they conclude that we should not suppress our feelings of envy. I argue, however, that these defenses only show that envy is sometimes morally permissible. In order to show that we would not be better off without envy, we must show how envy (...) is not merely morally permissible, but morally valuable. Here I provide a defense of envy's moral value. I argue that feelings of envy are integral to the value that moral agents place on the goods and talents that they judge to be central to a worthwhile life. (shrink)

This is my introduction as editor to The Cambridge Companion to Schleiermacher.

This paper explores three important criticisms of Kant's ethics by Friedrich Schleiermacher, all having to do with Kant's alleged failure to account for the value of the individual. These are: (1) Kant's formalism precludes him from specifying ends for the will, and without such ends, the moral perfection of the individual, and the genuine appreciation of the other in his or her individuality cannot become my end; (2) Kant cannot provide an adequate metaphysical grounding of the value of the individuals (...) comprising a community; (3) Kant cannot give an account of why members of a community should value the individual qua individual in relation to the community. In this paper I discuss these criticisms and their validity in detail. I show that understood properly, Kant has the resources to answer Schleiermacher's first criticism, and I show how Schleiermacher's own system sought to avoid the second and third problems. (shrink)

This article explores the later Schleiermacher’s metaphysics of substance and what it entails concerning the question of transcendental freedom. I show that in espousing a metaphysics of substance, Schleiermacher also abandoned an understanding of nature as a mere mechanism, a view implying what I call a “state-state view of causation” (“SSV” for short). Adoption of the view of the self as substance was motivated by the primacy of practical and religious concerns in Schleiermacher’s later work: in Christian Faith, an analysis (...) of self-consciousness from a first person point of view grounds this understanding of the self. In fact, in Christian Faith, ontology, and thereby theology, is only possible through such a first person analysis. The development of Schleiermacher’s views over time, and the reasons accompanying this development, can be fully understood only the in the context of his engagement with the work of Spinoza, Leibniz, and Kant. In what follows I trace this development through an analysis of the philosophical problems and influences shaping Schleiermacher’s mature view, and shed light on his understanding of self-consciousness and its relation to God. My own account should also serve to correct some recent misunderstandings that have made their way into the secondary literature. (shrink)

Our emotions can be revealing. They can not only reflect our character traits and our judgments, but they can also tell us things about ourselves that we do not fully realize or may not want to admit. In this chapter, I am particularly interested in how we relate to what I will call alienated emotions: emotional experiences that are unusual, surprising, or even disturbing. What, if anything, do our alienated emotions tell us about who we are? I argue here that (...) alienated emotions lead to important questions about the ethics of self-interpretation. (shrink)

Attitudes like shame and contempt seem to be at odds with basic tenets of Kantian moral theory. I argue on the contrary that both attitudes play a central role in Kantian morality. Shame and contempt are attitudes that protect our love of honour, or the esteem we have for ourselves as moral persons. The question arises: how are these attitudes compatible with Kant's claim that all persons deserve respect? I argue that the proper object of shame and contempt is not (...) the humanity within a person, but rather her self-conceit, or the false esteem that competes with love of honour. (shrink)

This paper examines the role of self-documentation in the care of the self. As is well known, Michel Foucault exposes how disciplinary power functions in hospitals, schools, prisons, and other institutions to train the living for productive use. An important tool of disciplinary power is documentation, or the recording and cataloguing of the living that constitutes them as objects of knowledge. I show how documentation creates and extends knowledge to individuals. At the same time, documents become physical appendages of the (...) lives they record, which, while separable from those lives, nevertheless affect those lives. Despite these apparently negative functions, Foucault finds that documentation can also be the means by which the living take over their own disciplining. In writings about both fiction and ancient ethics, Foucault points to self-documentation as a way of objectifying the self before the self, so that the self may train itself according to self-imposed standards. Although disciplinary power may be inescapable, self-documentation offers a technique of counter-discipline that functions alongside and against institutional discipline. (shrink)

Descriptive accounts of the nature of explanation in neuroscience and the global goals of such explanation have recently proliferated in the philosophy of neuroscience and with them new understandings of the experimental practices of neuroscientists have emerged. In this paper, I consider two models of such practices; one that takes them to be reductive; another that takes them to be integrative. I investigate those areas of the neuroscience of learning and memory from which the examples used to substantiate these models (...) are culled, and argue that the multiplicity of experimental protocols used in these research areas presents specific challenges for both models. In my view, these challenges have been overlooked largely because philosophers have hitherto failed to pay sufficient attention to fundamental features of experimental practice. I demonstrate that when we do pay attention to such features, evidence for reduction and integrative unity in neuroscience is simply not borne out. I end by suggesting some new directions for the philosophy of neuroscience that pertain to taking a closer look at the nature of neuroscientific experiments. (shrink)

Kant’s non-voluntarist conception of political obligation has led some philosophers to argue that he would reject self-government rights for indigenous peoples. Some recent scholarship suggests, however, that Kant’s critique of colonialism provides an argument in favor of granting self-government rights. Here I argue for a stronger conclusion: Kantian political theory not only can but must include sovereignty for indigenous peoples. Normally these rights are considered redress for historic injustice. On a Kantian view, however, I argue that they are not remedial. (...) Sovereignty rights are a necessary part of establishing perpetual peace. By failing to acknowledge the sovereignty of native groups, states once guilty of imperialism leave open the in principle possibility for future violence, even though no current conflict exists. Only in recognizing self-government rights can states truly commit to the cosmopolitan ideal. (shrink)

What can contemporary machine learning (ML) models do? Given the proliferation of ML models in society, answering this question matters to a variety of stakeholders, both public and private. The evaluation of models' capabilities is rapidly emerging as a key subfield of modern ML, buoyed by regulatory attention and government grants. Despite this, the notion of an ML model possessing a capability has not been interrogated: what are we saying when we say that a model is able to do something? (...) And what sorts of evidence bear upon this question? -/- In this paper, we aim to answer these questions, using the capabilities of large language models (LLMs) as a running example. Drawing on the large philosophical literature on abilities, we develop an account of ML models' capabilities which can be usefully applied to the nascent science of model evaluation. Our core proposal is a conditional analysis of model abilities (CAMA): crudely, a machine learning model has a capability to X just when it would reliably succeed at doing X if it 'tried'. The main contribution of the paper is making this proposal precise in the context of ML, resulting in an operationalisation of CAMA applicable to LLMs. We then put CAMA to work, showing that it can help make sense of various features of ML model evaluation practice, as well as suggest procedures for performing fair inter-model comparisons.

The essay discusses F. Schleiermacher and Rudolf Otto on the centrality of religious experience.

The use of child soldiers in armed conflict is an increasing global concern. Although philosophers have examined whether child soldiers can be considered combatants in war, much less attention has been paid to their moral responsibility. While it is tempting to think of them as having diminished or limited responsibility, child soldiers often report feeling guilt for the wrongs they commit. Here I argue that their feelings of guilt are both intelligible and morally appropriate. The feelings of guilt that child (...) soldiers experience are not self-censure; rather their guilt arises from their attempts to come to terms with what they see as their own morally ambiguous motives. Their guilt is appropriate because it reaffirms their commitment to morality and facilitates their self-forgiveness. (shrink)

This paper takes stock of Leibnizian influences on Schleiermacher's thought through an examination and comparison of the views of Leibniz, Kant, and Schleiermacher on predication. I analyze each thinker's foundational ontological and epistemological commitments and their implications for their understanding of predication. More specifically, I explore whether Schleiermacher's adoption of Leibiniz' theory of the complete concept and the theory of prediction it entails conflicts with his adoption of Kant's two-source theory of knowledge. I conclude that it does, and that it (...) is this clash between elements borrowed from two very different systematic thinkers that makes Schleiermacher's Dialektik the cipher that it is. (shrink)

The Morris water maze has been put forward in the philosophy of neuroscience as an example of an experimental arrangement that may be used to delineate the cognitive faculty of spatial memory (e.g., Craver and Darden, Theory and method in the neurosciences, University of Pittsburgh Press, Pittsburgh, 2001; Craver, Explaining the brain: Mechanisms and the mosaic unity of neuroscience, Oxford University Press, Oxford, 2007). However, in the experimental and review literature on the water maze throughout the history of its use, (...) we encounter numerous responses to the question of “what” phenomenon it circumscribes ranging from cognitive functions (e.g., “spatial learning”, “spatial navigation”), to representational changes (e.g., “cognitive map formation”) to terms that appear to refer exclusively to observable changes in behavior (e.g., “water maze performance”). To date philosophical analyses of the water maze have not been directed at sorting out what phenomenon the device delineates nor the sources of the different answers to the question of what. I undertake both of these tasks in this paper. I begin with an analysis of Morris’s first published research study using the water maze and demonstrate that he emerged from it with an experimental learning paradigm that at best circumscribed a discrete set of observable changes in behavior. However, it delineated neither a discrete set of representational changes nor a discrete cognitive function. I cite this in combination with a reductionist-oriented research agenda in cellular and molecular neurobiology dating back to the 1980s as two sources of the lack of consistency across the history of the experimental and review literature as to what is under study in the water maze.

Kant’s conception of mental illness is unlikely to satisfy contemporary readers. His classifications of mental illness are often fluid and ambiguous, and he seems to attribute to human beings at least some responsibility for preventing mental illness. In spite of these apparent disadvantages, I argue that Kant’s account of mental illness can be illuminating to his views about the normative dimensions of human cognition. In contrast to current understandings of mental illness, Kant’s account is what I refer to as “non-pathological.” (...) That is, most mental illnesses are for Kant continuous with normally functioning cognition. Someone with a healthy reason can easily fall into mental illness and someone with mental illness can (perhaps not as easily) re-establish healthy reason. By accepting a non-pathological definition of mental illness, it follows for Kant that humans have more agency and responsibility regarding their mental health than current views allow, which explains why several of his writings aim to prescribe a “diet of the mind” (2:271). Contrary to popular readings of Kant as a champion of reason’s power, Kant’s conception of mental illness shows that he recognizes how fragile human reason can be. (shrink)

This paper offers a critique of an account of explanatory integration that claims that explanations of cognitive capacities by functional analyses and mechanistic explanations can be seamlessly integrated. It is shown that achieving such explanatory integration requires that the terms designating cognitive capacities in the two forms of explanation are stable but that experimental practice in the mind-brain sciences currently is not directed at achieving such stability. A positive proposal for changing experimental practice so as to promote such stability is (...) put forward and its implications for explanatory integration are briefly considered. (shrink)

This paper explores Kant's concept of the highest good and the postulate of the existence of God arising from it. Kant has two concepts of the highest good standing in tension with one another, an immanent and a transcendent one. I provide a systematic exposition of the constituents of both variants and show how Kant’s arguments are prone to confusion through a conflation of both concepts. I argue that once these confusions are sorted out Kant’s claim regarding the need to (...) postulate God’s existence from a moral point of view makes much more sense. (shrink)

Despite its centrality in the philosophy of cognitive science, there has been little prior philosophical work engaging with the notion of representation in contemporary NLP practice. This paper attempts to fill that lacuna: drawing on ideas from cognitive science, I introduce a framework for evaluating the representational claims made about components of neural NLP models, proposing three criteria with which to evaluate whether a component of a model represents a property and operationalising these criteria using probing classifiers, a popular analysis (...) technique in NLP (and deep learning more broadly). The project of operationalising a philosophically-informed notion of representation should be of interest to both philosophers of science and NLP practitioners. It affords philosophers a novel testing-ground for claims about the nature of representation, and helps NLPers organise the large literature on probing experiments, suggesting novel avenues for empirical research.

Abstract: Heart diseases are increasing daily at a rapid rate and it is alarming and vital to predict heart diseases early. The diagnosis of heart diseases is a challenging task i.e. it must be done accurately and proficiently. The aim of this study is to determine which patient is more likely to have heart disease based on a number of medical features. We organized a heart disease prediction model to identify whether the person is likely to be diagnosed with a (...) heart disease or not using the medical features of the person. We used many different algorithms of machine learning such as Gaussian Mixture, Nearest Centroid, MultinomialNB, Logistic RegressionCV, Linear SVC, Linear Discriminant Analysis, SGD Classifier, Extra Tree Classifier, Calibrated ClassifierCV, Quadratic Discriminant Analysis, GaussianNB, Random Forest Classifier, ComplementNB, MLP Classifier, BernoulliNB, Bagging Classifier, LGBM Classifier, Ada Boost Classifier, K Neighbors Classifier, Logistic Regression, Gradient Boosting Classifier, Decision Tree Classifier, and Deep Learning to predict and classify the patient with heart disease. A quite helpful approach was used to regulate how the model can be used to improve the accuracy of prediction of heart diseases in any person. The strength of the proposed model was very satisfying and was able to predict evidence of having a heart disease in a particular person by using Deep Learning and Random Forest Classifier which showed a good accuracy in comparison to the other used classifiers. The proposed heart disease prediction model will enhances medical care and reduces the cost. This study gives us significant knowledge that can help us predict the person with heart disease. The dataset was collected from Kaggle depository and the model is implemented using python. (shrink)

In Two Minds is a practical casebook of problem solving in psychiatric ethics. Written in a lively and accessible style, it builds on a series of detailed case histories to illustrate the central place of ethical reasoning as a key competency for clinical work and research in psychiatry. Topics include risk, dangerousness and confidentiality; judgements of responsibility; involuntary treatment and mental health legislation; consent to genetic screening; dual role issues in child and adolescent psychiatry; needs assessment; cross-cultural and gender issues; (...) rational and irrational suicide; shared decision making in multi-agency teams, and the growing role of the user's voice in psychiatry. Key ethical concepts are carefully introduced and explained. The text is richly supported by detailed guides for further reading. There are separate chapters on teaching psychiatric ethics, including a sample seminar, and on writing a research ethics application. Each case history and discussion is followed by a critical commentary from a practitioner with relevant experience. Jim Birley adds a comparative international perspective on psychiatric ethics. Cartoons by Johnny Cowee provide punchy counterpoint! In Two Minds is the sister volume to the third edition of Sidney, Paul Chodoff and Steven Green's highly successful Psychiatric Ethics. In providing a bridge between theory and practice, it will be essential reading for everyone concerned with improving standards in mental health care. (shrink)

In a recent letter, Dillion et. al (2023) make various suggestions regarding the idea of artificially intelligent systems, such as large language models, replacing human subjects in empirical moral psychology. We argue that human subjects are in various ways indispensable.

Foundational ontologies, central constructs in ontological investigations and engineering alike, are based on ontological categories. Firstly proposed by Aristotle as the very ur- elements from which the whole of reality can be derived, they are not easy to identify, let alone partition and/or hierarchize; in particular, the question of their number poses serious challenges. The late medieval philosopher Dietrich of Freiberg wrote around 1286 a tutorial that can help us today with this exceedingly difficult task. In this paper, I discuss (...) ontological categories and their importance for foundational ontologies from both the contemporary perspective and the original Aristotelian viewpoint, I provide the translation from the Latin into English of Dietrich's De origine II with an introductory elaboration, and I extract a foundational ontology–that is in fact a single-category one–from this text rooted in Dietrich's specification of types of subjecthood and his conception of intentionality as causal operation.

In the 1706 third edition of her Reflections upon Marriage, Mary Astell alludes to John Locke’s definition of slavery in her descriptions of marriage. She describes the state of married women as being ‘subject to the inconstant, uncertain, unknown, Arbitrary Will of another Man’ (Locke, Two Treatises, II.22). Recent scholars maintain that Astell does not seriously regard marriage as a form of slavery in the Lockean sense. In this paper, I defend the contrary position: I argue that Astell does seriously (...) regard marriage as a form of slavery for women and that she condemns this state of affairs as morally wrong. I also show that, far from criticizing Locke, Astell draws on key passages in his Thoughts concerning Education to urge that women be educated to retain their liberty. (shrink)

Ontologies are some of the most central constructs in today's large plethora of knowledge technologies, namely in the context of the semantic web. As their coinage indicates, they are direct heirs to the ontological investigations in the long Western philosophical tradition, but it is not easy to make bridges between them. Contemporary ontological commitments often take causality as a central aspect for the ur-segregation of entities, especially in scientific upper ontologies; theories of causality and philosophical ontological investigations often go hand-in-hand, (...) and were essentially inseparable in medieval thought. This constitutes the foundation for a bridge, and this article analyzes the causality-based ontology of the late medieval philosopher Dietrich of Freiberg from the viewpoint of today's upper-ontology engineering. In this bridging attempt, it offers a translation into English of the first part of Dietrich's De origine (abbreviated title) that is a compromise between traditional scholarly translations of medieval Latin philosophical texts and contemporary ontology.

The van Wijngaarden grammars are two-level grammars that present many interesting properties. In the present article I elaborate on six of these properties, to wit, (i) their being constituted by two grammars, (ii) their ability to generate (possibly infinitely many) strict languages and their own metalanguage, (iii) their context-sensitivity, (iv) their high descriptive power, (v) their productivity, or the ability to generate an infinite number of production rules, and (vi) their equivalence with the unrestricted, or Type-0, Chomsky grammars.

I critically examine the semantic view of theories to reveal the following results. First, models in science are not the same as models in mathematics, as holders of the semantic view claim. Second, when several examples of the semantic approach are examined in detail no common thread is found between them, except their close attention to the details of model building in each particular science. These results lead me to propose a deflationary semantic view, which is simply that model construction (...) is an important component of theorizing in science. This deflationary view is consistent with a naturalized approach to the philosophy of science. (shrink)

I argue that an individual has aspects numerically identical with it and each other that nonetheless qualitatively differ from it and each other. This discernibility of identicals does not violate Leibniz's Law, however, which concerns only individuals and is silent about their aspects. They are not in its domain of quantification. To argue that there are aspects I will appeal to the internal conflicts of conscious beings. I do not mean to imply that aspects are confined to such cases, but (...) the best way to start is to recognize them experientially. We can feel the conflicts within ourselves. In doing so we can feel some of our aspects. I will try to enhance our understanding of the concept of aspect by listing and formalizing some principles for its use. After that I will argue that all sorts of individual things have aspects, not just people who are conflicted. (shrink)

Twentieth century philosophers introduced the distinction between “objective rightness” and “subjective rightness” to achieve two primary goals. The first goal is to reduce the paradoxical tension between our judgments of (i) what is best for an agent to do in light of the actual circumstances in which she acts and (ii) what is wisest for her to do in light of her mistaken or uncertain beliefs about her circumstances. The second goal is to provide moral guidance to an agent who (...) may be uncertain about the circumstances in which she acts, and hence is unable to use her standard moral principle directly in deciding what to do. This paper distinguishes two important senses of “moral guidance”; proposes criteria of adequacy for accounts of subjective rightness; canvasses existing definitions for “subjective rightness”; finds them all deficient; and proposes a new and more successful account. It argues that each comprehensive moral theory must include multiple principles of subjective rightness to address the epistemic situations of the full range of moral decision-makers, and shows that accounts of subjective rightness formulated in terms of what it would reasonable for the agent to believe cannot provide that guidance. -/- .

Many scholars point to the close association between early modern science and the rise of rational arguments in favour of the existence of witches. For some commentators, it is a poor reflection on science that its methods so easily lent themselves to the unjust persecution of innocent men and women. In this paper, I examine a debate about witches between a woman philosopher, Margaret Cavendish , and a fellow of the Royal Society, Joseph Glanvill . I argue that Cavendish is (...) the voice of reason in this exchange—not because she supports the modern-day view that witches do not exist, but because she shows that Glanvill’s arguments about witches betray his own scientific principles. Cavendish’s responses to Glanvill suggest that, when applied consistently, the principles of early modern science could in fact promote a healthy scepticism toward the existence of witches. (shrink)

You may not know me well enough to evaluate me in terms of my moral character, but I take it you believe I can be evaluated: it sounds strange to say that I am indeterminate, neither good nor bad nor intermediate. Yet I argue that the claim that most people are indeterminate is the conclusion of a sound argument—the indeterminacy paradox—with two premises: (1) most people are fragmented (they would behave deplorably in many and admirably in many other situations); (2) (...) fragmentation entails indeterminacy. I support (1) by examining psychological experiments in which most participants behave deplorably (e.g., by maltreating “prisoners” in a simulated prison) or admirably (e.g., by intervening in a simulated theft). I support (2) by arguing that, according to certain plausible conceptions, character evaluations presuppose behavioral consistency (lack of fragmentation). Possible reactions to the paradox include: (a) denying that the experiments are relevant to character; (b) upholding conceptions according to which character evaluations do not presuppose consistency; (c) granting that most people are indeterminate and explaining why it appears otherwise. I defend (c) against (a) and (b). (shrink)

Imperatives cannot be true or false, so they are shunned by logicians. And yet imperatives can be combined by logical connectives: "kiss me and hug me" is the conjunction of "kiss me" with "hug me". This example may suggest that declarative and imperative logic are isomorphic: just as the conjunction of two declaratives is true exactly if both conjuncts are true, the conjunction of two imperatives is satisfied exactly if both conjuncts are satisfied—what more is there to say? Much more, (...) I argue. "If you love me, kiss me", a conditional imperative, mixes a declarative antecedent ("you love me") with an imperative consequent ("kiss me"); it is satisfied if you love and kiss me, violated if you love but don't kiss me, and avoided if you don't love me. So we need a logic of three -valued imperatives which mixes declaratives with imperatives. I develop such a logic. (shrink)

According to some scholars, Mary Astell’s feminist programme is severely limited by its focus on self-improvement rather than wider social change. In response, I highlight the role of ‘virtuous friendship’ in Astell’s 1694 work, A Serious Proposal to the Ladies. Building on classical ideals and traditional Christian principles, Astell promotes the morally transformative power of virtuous friendship among women. By examining the significance of such friendship to Astell’s feminism, we can see that she did in fact aim to bring about (...) reformation of society and not just the individual. (shrink)

Conceptions of acceptability-based moral or political justification take it that authoritative acceptability constitutes, or contributes to, validity, or justification. There is no agreement as to what bar for authoritativeness such justification may employ. The paper engages the issue in relation to (i) the level of idealization that a bar for authoritativeness, ψ, imparts to a standard of acceptability-based justification, S, and (ii) the degree of discursive purchase of the discursive standing that S accords to people when it builds ψ. I (...) argue that (i) and (ii) are interdependent: high idealization values entail low discursive purchase, while high degrees of purchase require low idealization values. I then distinguish between alethic conceptions of justification that prioritize ends that commit to high idealization values, and recognitive conceptions that favour high discursive purchase. On this basis, I argue for a moderately recognitivist constraint on idealization. To render the recognitive discursive minimum available to relevant people at the site of justification, S should set ψ low enough so that it is a genuine option for actual people to reject relevant views in ways that S recognizes as authoritative.

Some scholars suggest that John Locke’s revisions to the chapter “Of Power” for the 1694 second edition of his Essay concerning Human Understanding may be indebted to the Cambridge Platonist, Ralph Cudworth. Their claims rest on evidence that Locke may have had access to Cudworth’s unpublished manuscript treatises on free will. In this paper, I examine an alternative suggestion – the claim that Cudworth’s daughter, Damaris Cudworth Masham, and not Cudworth himself, may have exerted an influence on Locke’s revisions. I (...) discuss the plausibility of this claim in light of the relevant historical and textual evidence. (shrink)

In the Bayesian approach to quantum mechanics, probabilities—and thus quantum states—represent an agent’s degrees of belief, rather than corresponding to objective properties of physical systems. In this paper we investigate the concept of certainty in quantum mechanics. Particularly, we show how the probability-1 predictions derived from pure quantum states highlight a fundamental difference between our Bayesian approach, on the one hand, and Copenhagen and similar interpretations on the other. We first review the main arguments for the general claim that probabilities (...) always represent degrees of belief. We then argue that a quantum state prepared by some physical device always depends on an agent’s prior beliefs, implying that the probability-1 predictions derived from that state also depend on the agent’s prior beliefs. Quantum certainty is therefore always some agent’s certainty. Conversely, if facts about an experimental setup could imply agent-independent certainty for a measurement outcome, as in many Copenhagen-like interpretations, that outcome would effectively correspond to a preexisting system property. The idea that measurement outcomes occurring with certainty correspond to preexisting system properties is, however, in conflict with locality. We emphasize this by giving a version of an argument of Stairs [(1983). Quantum logic, realism, and value-definiteness. Philosophy of Science, 50, 578], which applies the Kochen–Specker theorem to an entangled bipartite system. (shrink)

For millennia, knowledge has eluded a precise definition. The industrialization of knowledge (IoK) and the associated proliferation of the so-called knowledge communities in the last few decades caused this state of affairs to deteriorate, namely by creating a trio composed of data, knowledge, and information (DIK) that is not unlike the aporia of the trinity in philosophy. This calls for a general theory of knowledge (ToK) that can work as a foundation for a science of knowledge (SoK) and additionally distinguishes (...) knowledge from both data and information. In this paper, I attempt to sketch this generality via the establishing of both knowledge structures and knowledge systems that can then be adopted/adapted by the diverse communities for the respective knowledge technologies and practices. This is achieved by means of a formal–indeed, mathematical–approach to epistemological matters a.k.a. formal epistemology. The corresponding application focus is on knowledge systems implementable as computer programs. (shrink)

Racial epithets are terms used to characterize people on the basis of their race, and are often used to harm the people that they target. But what do racial epithets mean, and how do they work to harm in the way that they do? In this essay I set out to answer these questions by offering a pragmatic view of racial epithets, while contrasting my position with Christopher Hom's semantic view.

Against those who dismiss Kant's project in the "Religion" because it provides a Pelagian understanding of salvation, this paper offers an analysis of the deep structure of Kant's views on divine justice and grace showing them not to conflict with an authentically Christian understanding of these concepts. The first part of the paper argues that Kant's analysis of these concepts helps us to understand the necessary conditions of the Christian understanding of grace: unfolding them uncovers intrinsic relations holding between God's (...) justice and grace. Parts two and three provide an analysis of two concepts of grace used by Kant. Getting clear on their differences is the key to understanding why Kant's account is not Pelagian. (shrink)

Empirical philosophers of science aim to base their philosophical theories on observations of scientific practice. But since there is far too much science to observe it all, how can we form and test hypotheses about science that are sufficiently rigorous and broad in scope, while avoiding the pitfalls of bias and subjectivity in our methods? Part of the answer, we claim, lies in the computational tools of the digital humanities, which allow us to analyze large volumes of scientific literature. Here (...) we advocate for the use of these methods by addressing a number of large-scale, justificatory concerns—specifically, about the epistemic value of journal articles as evidence for what happens elsewhere in science, and about the ability of DH tools to extract this evidence. Far from ignoring the gap between scientific literature and the rest of scientific practice, effective use of DH tools requires critical reflection about these relationships. (shrink)

Biological evolution is a complex blend of ever changing structural stability, variability and emergence of new phe- notypes, niches, ecosystems. We wish to argue that the evo- lution of life marks the end of a physics world view of law entailed dynamics. Our considerations depend upon dis- cussing the variability of the very ”contexts of life”: the in- teractions between organisms, biological niches and ecosys- tems. These are ever changing, intrinsically indeterminate and even unprestatable: we do not know ahead of (...) time the ”niches” which constitute the boundary conditions on selec- tion. More generally, by the mathematical unprestatability of the ”phase space”, no laws of mo- tion can be formulated for evolution. We call this radical emergence, from life to life. The purpose of this paper is the integration of variation and diversity in a sound concep- tual frame and situate unpredictability at a novel theoretical level, that of the very phase space. Our argument will be carried on in close comparisons with physics and the mathematical constructions of phase spaces in that discipline. The role of symmetries as invariant preserving transformations will allow us to under- stand the nature of physical phase spaces and to stress the differences required for a sound biological theoretizing. In this frame, we discuss the novel notion of ”enablement”. Life lives in a web of enablement and radical emergence. This will restrict causal analyses to differential cases. Mutations or other causal differ- ences will allow us to stress that ”non conservation princi- ples” are at the core of evolution, in contrast to physical dynamics, largely based on conservation principles as sym- metries. Critical transitions, the main locus of symmetry changes in physics, will be discussed, and lead to ”extended criticality” as a conceptual frame for a better understanding of the living state of matter.

In this chapter, I argue that scientific practice in the neurosciences of cognition is not conducive to the discovery of natural kinds of cognitive capacities. The “neurosciences of cognition” include cognitive neuroscience and cognitive neurobiology, two research areas that aim to understand how the brain gives rise to cognition and behavior. Some philosophers of neuroscience have claimed that explanatory progress in these research areas ultimately will result in the discovery of the underlying mechanisms of cognitive capacities. Once such mechanistic understanding (...) is achieved, cognitive capacities purportedly will be relegated into natural kind categories that correspond to real divisions in the causal structure of the world. I provide reasons here, however, in support of the claim that the neurosciences of cognition currently are not on a trajectory for discovering natural kinds. As I explain, this has to do with how mechanistic explanations of cognitive capacities are developed. Mechanistic explanations and the kinds they explain are abstract representational byproducts of the conceptual, experimental and integrative practices of neuroscientists. If these practices are not coordinated towards developing mechanistic explanations that mirror the causal structure of the world, then natural kinds of cognitive capacities will not be discovered. I provide reasons to think that such coordination is currently lacking in the neurosciences of cognition and indicate where changes in these practices appropriate to the natural kinds ideal would be required if achieving this ideal is indeed the goal. However, I suggest that an evaluation of current practices in these research areas is suggestive that discovering natural kinds of cognitive capacities is not the goal. (shrink)

This paper explores the idea of robust discursive equality on which respect-based conceptions of justificatory reciprocity often draw. I distinguish between formal and substantive discursive equality and argue that if justificatory reciprocity requires that people be accorded formally equal discursive standing, robust discursive equality should not be construed as requiring standing that is equal substantively, or in terms of its discursive purchase. Still, robust discursive equality is purchase sensitive: it does not obtain when discursive standing is impermissibly unequal in purchase. (...) I then showcase different candidate conceptions of purchase justice, and draw conclusions about the substantive commitments of justificatory reciprocity. (shrink)
