"Naked life": the vital meaning of nutrition in Claude Bernard's physiology.

The aim of this paper is to elucidate the vital meaning and strategic role that nutrition holds in Claude Bernard's  "biological philosophy", in the sense Auguste Comte gave to this expression, i.e. the theoretical part of biology. I propose that Bernard's nutritive perspective on life should be thought of as an  "interfield" object, following Holmes' category. Not only does nutrition bridge disciplines like physiology and organic chemistry, as well as levels of inquiry ranging from special physiology to the organism's total level, including the cell and protoplasm, but it also forms the genetic and structural foundation for Bernard's two fundamental axioms in general physiology: the necessary complementarity of destruction and creation (1) and the uniformity of this physiological law across all life forms, be it plants or animals (2). Because Bernard's nutritive theory is a major pivot for the re-ordering of life and its characterization, I argue that it must be located and understood in the scientific and metaphysical context of his time, of which he claims to be the heir and challenger-what I propose to characterize as the  "epistemic space" of nutrition, on the background of which Bernard builds his own  "logic". I then set out this logic of nutrition, focusing on three interrelated bernardian theses: the establishment of the theory of indirect nutrition as the basis for the notion of  "milieu intérieur"; the enduring conception of nutrition as a continuous generation; the emphasis on nutrition as a way of reshaping the form/matter relationship.

Psychopathology and Metaphysics: Can One Be a Realist About Mental Disorder?

Metaphysical realism about mental disorder is the thesis that mental disorder exists mind-independently. There are two ways to challenge metaphysical realism about mental disorder. The first is by denying that mental disorder exists. The second is by denying that mental disorder exists mind-independently. Or, differently put, by arguing that mental disorder is mind-dependent. The aim of this paper is three-fold: (a) to examine three ways in which mental disorder can be said to be mind-dependent (namely, by being causally dependent on the human mind, by being weakly dependent on human attitudes, and by being strongly dependent on human attitudes), (b) to clarify their differences, and (c) to discuss their implications regarding metaphysical realism about mental disorder. I argue that mental disorder being mind-dependent in the first two senses is compatible with metaphysical realism about mental disorder, whereas mental disorder being mind-dependent in the third sense is not.

Minimal logical teleology in artifacts and biology connects the two domains and frames mechanisms via epistemic circularity.

The understanding of artifacts and biological phenomena has often influenced each other. This work argues that at the core of these epistemic bridges there are shared teleological notions and explanations manifested in analogies between artifacts and biological phenomena. To this end, I first propose a focus on the logical structure of minimal teleological explanations, which renders said epistemic bridges more evident than an ontological or metaphysical approach to teleology, and which can be used to describe scientific practices in different areas by virtue of formal generality and minimalism (section 2). Second, I show how this approach highlights some epistemic features shared by the understanding of artifacts and biological phenomena, like a specific kind of epistemic circularity, and how functional analogies between artifacts and biological phenomena translate such epistemic circularity from one domain to the other (section 3). Third, I conduct a case study on the scientific practice around the brain's "compass", showing how the understanding of artifacts influences purpose ascription and measurement, and frames mechanisms in biology, especially in areas where purpose ascription is most difficult, like cognitive neuroscience (sections 4 and 5).

On compatibility between realism and fictionalism: A response to Suárez' proposal.

In a series of articles, Mauricio Suárez defends the neutrality of fictionalism with respect to the scientific realism-anti-realism debate. Suárez understands fictionalism from a strictly methodological point of view, linked to the practice of model building in the context of the philosophy of science. He moves away from the type of fictionalism analysed in other areas of philosophy such as metaphysics, the philosophy of language, aesthetics or the philosophy of mathematics. Following Vaihinger's position, he emphasizes the inferential role of fiction in scientific modelling and argues that scientific fictionalism is not incompatible with scientific realism, as is often believed. We argue against Suárez's position and reject the ubiquitous character assigned to fictions in scientific discourse, as well as the deflationary view of scientific realism defended by Suárez. We conclude that when the semantic, epistemic, and metaphysical aspects at stake in the realism-antirealism debate are taken into account, the alleged compatibility between scientific realism and fictionalism starts to generate some tension.

Heterodox underdetermination: Metaphysical options for discernibility and (non-)entanglement.

Broadly speaking, there are three views on whether Leibniz's Principle of the Identity of Indiscernibles (PII) is violated in the case of similar particles. According to the earliest view, PII is always violated (call this the no discernibility view); according to the more recent weak discernibility view, PII is at least valid in a weak sense. No and weak discernibility have been referred to as orthodoxy. Steven French has argued that although PII is violated, similar particles can still be regarded as individuals, or, alternatively, as non-individuals: French famously concluded therefore that metaphysics is underdetermined by physics. Call this thesis orthodox underdetermination. Most recently, some authors have turned against orthodoxy by arguing that PII is valid in more than a weak sense - call this the new discernibility view, also referred to as heterodoxy. Since heterodoxy is backed up by physical considerations, metaphysics now seems to be determined by physics: physics indicates that PII is valid. In this paper, I argue that with respect to entangled states, there are two ways to establish PII's validity, which yield two different ontological interpretations of entanglement. Therefore, a form of underdetermination returns within the heterodox framework. I argue that heterodox underdetermination deserves some attention, because the two ontological interpretations might yield different explanations of the violation of Bell inequalities.

Claude Bernard's non reception of Darwinism.

The aim of this paper is to explain why, while Charles Darwin was well recognized as a scientific leader of his time, Claude Bernard never really regarded Darwinism as a scientific theory. The lukewarm reception of Darwin at the Académie des Sciences of Paris and his nomination to a chair only after 8 years contrasts with his prominence, and Bernard's attitude towards Darwin's theory of species evolution belongs to this French context. Yet we argue that Bernard rejects the scientific value of Darwinian principles mainly for epistemological reasons. Like Darwin, Bernard was interested in hereditary processes, and planned to conduct experiments on these processes that could lead to species transformation. But the potential creation of new forms of life would not vindicate Darwinism since biologists can only explain the origin of morphotypes and morphological laws by the means of untestable analogies. Because it can be the object neither of experiments nor of any empirical observation, phylogeny remains out of science's scope. Around 1878 Bernard foresaw a new general physiology based on the study of protoplasm, which he saw as the agent of all basic living phenomena. We will analyze why Bernard regarded Darwinism as part of metaphysics, yet still referred to Darwinians in his latter works in 1878. Basically, the absence of a scientific reception of Darwinism in Bernard's work should not obscure its philosophical reception, which highlights the main principles of Bernard's epistemology.

Physiology, Vitalism, and the Contest for Body and Soul in the Antebellum United States.

In the early nineteenth century, physiology became an increasingly popular and powerful science in the United States. Religious controversy over the nature of human vitality animated much of this interest. On one side of these debates stood Protestant apologists who wedded an immaterialist vitalism to their belief in an immaterial, immortal soul - and therefore to their dreams of a Christian republic. On the other side, religious skeptics argued for a materialist vitalism that excluded anything immaterial from human life, aspiring thereby to eliminate religious interference in the progress of science and society. Both sides hoped that by claiming physiology for their vision of human nature they might direct the future of religion in the US. Ultimately, they failed to realize these ambitions, but their contest posed a dilemma late nineteenth-century physiologists felt compelled to solve: how should they comprehend the relationship between life, body, and soul? Eager to undertake laboratory work and leave metaphysical questions behind, these researchers solved the problem by restricting their work to the body while leaving spiritual matters to preachers. In attempting to escape the vitalism and soul questions, late nineteenth-century Americans thus created a division of labor that shaped the history of medicine and religion for the following century.

The Mereotopology of Pregnancy.

Consider the following two metaphysical questions about pregnancy: (1) When does a new organism of a certain kind start to exist? (2) What is the mereological and topological relationship between the pregnant organism and with what it is pregnant? Despite assumptions made in the literature, I take these questions to be independent of each other, such that an answer to one does not provide an answer to the other. I argue that the way to connect them is via a maximality principle that prevents one organism being a proper part of another organism of the same kind. That being said, such a maximality principle need not be held, and may not apply in the case of pregnancy. The aims of this paper are thus to distinguish and connect these metaphysical questions, in order to outline a taxonomy of rival mereotopological models of pregnancy that result from the various combinations of their answers.

The essentialism of early modern psychiatric nosology.

Are psychiatric disorders natural kinds? This question has received a lot of attention within present-day philosophy of psychiatry, where many authors debate the ontology and nature of mental disorders. Similarly, historians of psychiatry, dating back to Foucault, have debated whether psychiatric researchers conceived of mental disorders as natural kinds or not. However, historians of psychiatry have paid little to no attention to the influence of (a) theories within logic, and (b) theories within metaphysics on psychiatric accounts of proper method, and on accounts of the nature and classification of mental disorders. Historically, however, logic and metaphysics have extensively shaped methods and interpretations of classifications in the natural sciences. This paper corrects this lacuna in the history of psychiatry, and demonstrates that theories within logic and metaphysics, articulated by Christian Wolff (1679-1754), have significantly shaped the conception of medical method and (psychiatric) nosology of the influential nosologist Boissier De Sauvages (1706-1767). After treating Sauvages, I discuss the method of the influential nosologist William Cullen (1710-1790), and demonstrate the continuity between the classificatory methods of Sauvages and Cullen. I show that both Sauvages and Cullen were essentialists concerning medical diseases in general and psychiatric disorders in particular, contributing to the history of conceptions of the ontology and nature of mental disorders.

What is attention? Adverbialist theories.

This article presents theories of attention that attempt to derive their answer to the question of what attention is from their answers to the question of what it is for some activity to be done attentively. Such theories provide a distinctive account of the difficulties that are faced by the attempt to locate processes in the brain by which the phenomena of attention can be explained. Their account does not share the pessimism of theories suggesting that the concept of attention is defective. Instead it reconstrues the explanatory relationship between attention and the processes that constitute it, in a way that is illustrated here by considering the relationship between attention and the processes that are identified by the biased competition theory. After considering some of the ways in which an adverbialist approach might be developed, the article concludes by suggesting some possible solutions to a problem concerning distraction, by which prominent adverbialist theories of attention have been dogged. This article is categorized under: Psychology > Attention Philosophy > Metaphysics Philosophy > Foundations of Cognitive Science.

Implications of philosophical pragmatism for nursing: Comparison of different pragmatists.

Pragmatism emphasizes practical consequences and empirical explanations rather than introspective contemplations. However, the arguments of pragmatists are not uniform, as shown by the four prominent pragmatists presented in this article. The major difference between them is that Peirce and Haack acknowledge an objective truth, whereas James and Rorty do not. Thus, for a fuller understanding of the pragmatist view of our knowledge, both camps must be consulted. In the nursing field, pragmatism is occasionally referred to as a guiding philosophy. However, the influence of James and Rorty has been greater than that of Peirce and Haack on pragmatists, which may risk leading to a skewed understanding of pragmatism by nursing scholars. Still, the four pragmatists share naturalism, which rejects a metaphysics that defines the nature of knowledge before our enquiry and emphasizes experience and practice. Pragmatic naturalism can help ensure that nursing theory does not deviate from clinical practice. This article also explores the broad adaptability of the ideas of all four pragmatists to philosophical issues in nursing, such as mixed-methods research, epistemic relativism and realism. By showing that pragmatism can be relevant and stimulating to each of these topics, the article demonstrates that the different approaches to pragmatism can provide more inspiration for nurses and nursing researchers in the future.

The metaphysics of fibre bundles.

Recently, Dewar (2019) has suggested that one can apply the strategy of 'sophistication'-as exemplified by sophisticated substantivalism as a response to the diffeomorphism invariance of General Relativity-to gauge theories such as electrodynamics. This requires a shift to the formalism of fibre bundles. In this paper, I develop and defend this suggestion. Where my approach differs from previous discussions is that I focus on the metaphysical picture underlying the fibre bundle formalism. In particular, I aim to affirm the physical reality of gauge properties. I argue that this allows for a local and separable explanation of the Aharonov-Bohm effect. Its puzzling features are explained by a form of holism inherent to fibre bundles.

A refreshed approach to homology-Prioritizing epistemology over metaphysics.

Unease with the inclusion of "sameness" in Owen's definition of homology characterizes a substantial part of the literature on this subject, where this term has acquired an increasingly strict metaphysical flavor. Taken for granted the existence of body features that are "the same," their existence has been explained by appealing to universal laws of form, as the product of common ancestry, or in terms of proximal causes responsible for the emergence of conserved developmental modules. However, a fundamentally different approach is possible, if we shift attention from metaphysics to epistemology. We may reword Owen's statement as follows: organs of different animals, in so far as they can be described as the same despite any difference in form and function, are called homologues. The proposed framework provides an umbrella for both the traditional, all-or-nothing concept of homology, and the less fashionable alternatives of factorial or partial homology, as well as for an extension of homology from form to function. No less attractive is the prospect to handle also ghost homologues, the body parts or organs of which there is non-objective evidence in a given clade, but can nevertheless be represented, in a description that encapsulates some of the traits observable in their extant homologue in the sister clade. Stripped of its different and constraining metaphysical explanations, homology survives as an anchor concept to which different nomadic disciplines and research agendas can be associated.

The post-metaphysical and conversational perspective of the self in Richard Rorty / A abordagem pós-metafísica e conversacional do self em richard rorty

RESUMO: O artigo enfoca a relevância de uma dimensão política no psíquico. Em nossa hermenêutica sobre o tema, em um primeiro momento, abordaremos as linhas gerais de uma ruptura com modelos filosóficos metafísicos do self, tendo como exemplo as críticas de Rorty e Heidegger à "intencionalidade de consciência" de Jean-Paul Sartre; bem como o contraponto rortiano à leitura epistemológica da psicanálise de Paul Ricoeur. Em uma segunda etapa, discutiremos a concepção rortiana de self por mostrar, ao final, seus possíveis limites com a abordagem antipredicativa de self.

Abstract: The article focuses the relevance of a political dimension in the psychic. In our hermeneutics on the theme, at first, we will approach the broad lines of a break with metaphysical philosophical models of the self, taking Rorty and Heidegger's criticisms of Jean-Paul Sartre's "intentionality of conscience" as an example; as well as the Rortian counterpoint to the epistemological reading of psychoanalysis by Paul Ricoeur. In a second step, we will debate the Rortian conception of the self for showing, in the end, its possible limits with the antipredicative approach to the self.

Enough blanket metaphysics, time for data-driven heuristics.

Bruineberg and colleagues criticisms' have been received but downplayed in the free energy principle (FEP) literature. We strengthen their points, arguing that Friston blanket discovery, even if tractable, requires a full formal description of the system of interest at the outset. Hence, blanket metaphysics is futile, and we postulate that researchers should turn back to heuristic uses of Pearl blankets.

More on realism, phenomenology, and causation, in reply to Cheng.

First, I agree with Cheng that the argument from illusions to indirect realism is controversial, especially as to what is meant by "realism," "veridical," and "sense data" and the background assumptions underlying them. I provide a finer specification of some of the sub-movements that were the specific concerns of my previous article, particularly phenomenology as it currently sees itself in perception research, and the relevance of illusions. Perception has turned out to be far more complex than traditional philosophy realized, as has been revealed by recent research in neuroscience and psychophysics. Lastly, I answer Cheng's question about the "causal exclusion argument" by suggesting it is obviated by the temporal substructure of metaphysical states, and I provide a detailed supporting case in Supplementary Material.

Illusions, objectivity, and non-reductive emergentism: Reply to Rose.

In the target article, David Rose makes an interesting and substantive case against a certain kind of sceptical view: "veridical perception is impossible in principle," combined with a certain version of anti-realism. He proceeds by first illustrating several ideas from George Orwell's seminal work, and then proposes that a certain kind of non-reductive, levelled emergentist metaphysics can help us respond to such scepticism. In this commentary, I join forces with Rose's case, but will point out that we need to take seriously two discussions in contemporary philosophy in order to make the realist case stronger: the argument from illusion and hallucination, and the causal exclusion argument. Only then do Rose and his allies can have a more satisfactory case for objectivity and realism.

Se analizan dos series que, con diferencia de quince años, abordan el tema de la maternidad subrogada: Shameless y Little fires everywhere, con el foco en las cuestiones bioéticas y sociales involucradas en ellas. A partir de los relatos de apego entre la gestante y la persona nacida o por nacer, se pone a prueba el concepto de "metafísica del embarazo", tal como lo trabaja Suki Finn, ofreciendo un escenario novedoso para un tema complejo y controvertido

Two series are analyzed that, with a difference of fifteen years, address the issue of surrogate motherhood: Shameless and Little fires everywhere, with a focus on the bioethical and social issues involved in them. From the stories of attachment between the pregnant woman and the person born or unborn, the concept of "metaphysics of pregnancy" is examined, as Suki Finn works, offering a novel scenario for a complex and controversial issue

Toward an Account of Intuitive Time.

People hold intuitive theories of the physical world, such as theories of matter, energy, and motion, in the sense that they have a coherent conceptual structure supporting a network of beliefs about the domain. It is not yet clear whether people can also be said to hold a shared intuitive theory of time. Yet, philosophical debates about the metaphysical nature of time often revolve around the idea that people hold one or more "common sense" assumptions about time: that there is an objective "now"; that the past, present, and future are fundamentally different in nature; and that time passes or flows. We empirically explored the question of whether people indeed share some or all of these assumptions by asking adults to what extent they agreed with a set of brief statements about time. Across two analyses, subsets of people's beliefs about time were found consistently to covary in ways that suggested stable underlying conceptual dimensions related to aspects of the "common sense" assumptions described by philosophers. However, distinct subsets of participants showed three mutually incompatible profiles of response, the most frequent of which did not closely match all of philosophers' claims about common sense time. These exploratory studies provide a useful starting point in attempts to characterize intuitive theories of time.
