The immune system does not just fight pathogens but also engages in interactions with beneficial microbes and non-immune cells of the body to harmonize their behavior by means of cytokines, antibodies and effector cells (Dinarello, 2007; Moticka, 2015, pp. 217e226, 261e267). However, the importance of these “housekeeping” functions has not been fully appreciated (Cohen, 2000). In his new book Immunity: The Evolution of an Idea Alfred I. Tauber traces the history of fundamental ideas in immunology and refers to recent advances (...) in the field to overturn the notion that immunity is the ability of an autonomous organism to protect itself against pathogens. Indeed, as suggested by the author, the autonomy of the organism is illusive because individuals develop as holobionts: functionally integrated multispecies consortia (p. 98). Similarly, he suggests that pathogenicity also emerges from the lack of subordination of a microbe to social welfare of the holobiont rather than from context-independent properties of this organism (pp. 165, 181). Emphasizing the contextual character of the parasite and the host, Tauber redefines immunity as an active process of coordination of a cellular ecosystem, which allows this collective to navigate through challenges of the environment and to face demands of the communal living (pp. 10e16). From this point of view, the failure to modulate intercellular interactions by the immune system entails mitigating immunity and impairing resistance to infection and disease (pp. 103e104). Immunity is a groundbreaking work establishing a new framework for understanding the function and activity of the immune system. Its value also lies in the fact that it serves as an important stepping-stone towards an integrated philosophical, ecological and immunological study of our embedment in the microbial world.

Philosophy of immunology is a subfield of philosophy of biology dealing with ontological and epistemological issues related to the studies of the immune system. While speculative investigations and abstract analyses have always been part of immune theorizing, until recently philosophers have largely ignored immunology. Yet the implications for understanding the philosophical basis of organismal functions framed by immunity offer new perspectives on fundamental questions of biology and medicine. Developed in the context of history of medicine, theoretical biology, and medical anthropology, (...) philosophy of immunology differs from these related branches of study in its focus on traditional philosophical questions concerning identity, individuality, ecology, cognition, scientific methodology and theory construction. This broad agenda derives from immunology’s multifaceted research program that has developed from its initial clinical challenges of host defense, transplantation, autoimmunity, tumor immunology, and allergy. In addition to these well-established research areas, immunity is now understood to play a central role in other physiological functions, development, ecology, and evolutionary mechanics. Holding together these diverse domains of inquiry lie philosophical commitments oriented by organismal identity. In this regard, pertinent issues are raised concerning cognition (organization of immune perception and information processing), the character of individuality (framed by the ecological context of immune-mediated assimilation and rejection), and the dynamics of complex systems (understood as holistic systems biology). Indeed, immunology, in the context of cognitive science, evolutionary biology, environmental sciences, and development provides multi-focal perspectives for philosophy of science. (shrink)

The extent to which normal (nonmalignant) cells of the body can evolve through mutation and selection during the lifetime of the organism has been a major unresolved issue in evolutionary and developmental studies. On the one hand, stable multicellular individuality seems to depend on genetic homogeneity and suppression of evolutionary conflicts at the cellular level. On the other hand, the example of clonal selection of lymphocytes indicates that certain forms of somatic mutation and selection are concordant with the organism-level fitness. (...) Recent DNA sequencing and tissue physiology studies suggest that in addition to adaptive immune cells also neurons, epithelial cells, epidermal cells, hematopoietic stem cells and functional cells in solid bodily organs are subject to evolutionary forces during the lifetime of an organism. Here we refer to these recent studies and suggest that the expanding list of somatically evolving cells modifies idealized views of biological individuals as radically different from collectives. (shrink)

Somatic diversification of antigen receptor genes depends on the activity of enzymes whose homologs participate in a mutagenic DNA repair in unicellular species. Indeed, by engaging error-prone polymerases, gap filling molecules and altered mismatch repair pathways, lymphocytes utilize conserved components of genomic stress response systems, which can already be found in bacteria and archaea. These ancient systems of mutagenesis and repair act to increase phenotypic diversity of microbial cell populations and operate to enhance their ability to produce fit variants during (...) stress. Coopted by lymphocytes, the ancient mutagenic processing systems retained their diversification functions instilling the adaptive immune cells with enhanced evolvability and defensive capacity to resist infection and damage. As reviewed here, the ubiquity and conserved character of specialized variation-generating mechanisms from bacteria to lymphocytes highlight the importance of these mechanisms for evolution of life in general.

There are philosophers of mind who believe that externalism with regard to mental content leads inevitably to the conclusion, that the mind should be identified with something external to the cognitive system. These philosophers are convinced that contents of our thoughts are not located in our heads on the basis of Putnam's belief that the contents of linguistic expressions are not located in head. The aim of this paper is to show that despite the above widespread convictions, externalism with regard (...) to mental content allows to identify mental states with the states of the cognitive system. If the question regarding the localization of the mind makes any sense, the mind has to be identified with the entity located within the cognitive system of an individual. I will show that an externalist is not in a position to identify the mental with contents of representational states of the cognitive system. She is unable to identify the mind and mental states with physical bearers too. What is the common mistake of these two options is an unacceptable idealization according to which it is possible to separate content from a bearer. The only possible option that externalist could embrace is the one that says that a mental state should be identified with physical bearers bearing content. Such bearers are the physical objects that thanks to the system in which they exist can stand for other objects. Form the externalistic point of view this power of standing for something is determined, at least partially, by external factors. (shrink)

It has long been taken for granted that the immune system’s capacity to protect an individual from infection and disease depends on the power of the system to distinguish between self and nonself. However, accumulating data have undermined this fundamental concept. Evidence against the self/nonself discrimination model left researchers in need of a new overarching framework able to capture the immune system’s reactivity. Here, I highlight that along with the self/nonself model, another powerful representation of the immune system’s reactivity has (...) been developed in the twentieth century immunology. According to this alternative view, the immune system is not a killer of nonself strangers but a peace-maker helping to establish harmony with the environment. The balance view of the system has never become part of the dominant paradigm. However, it is gaining more and more currency as new research develops. Advances in mucosal immunology confirm that instead of distinguishing between self and foreign the immune system reacts to microbial, chemical and self-induced alterations to produce responses that counterbalance effects of these changes. (shrink)

The immune system, to protect the body, must discriminate between the pathogenic and non-pathogenic microbes and respond to them in different ways. How the mucosal immune system manages to make this distinction is poorly understood. We suggest here that the distinction between pathogenic and non-pathogenic microbes is made by an integrated system rather than by single types of cells or single types of receptors; a systems biology approach is needed to understand immune recognition.

Advocates of the computational theory of mind claim that the mind is a computer whose operations can be implemented by various computational systems. According to these philosophers, the mind is multiply realisable because—as they claim—thinking involves the manipulation of syntactically structured mental representations. Since syntactically structured representations can be made of different kinds of material while performing the same calculation, mental processes can also be implemented by different kinds of material. From this perspective, consciousness plays a minor role in mental (...) activity. However, contemporary neuroscience provides experimental evidence suggesting that mental representations necessarily involve consciousness. Consciousness does not only enable individuals to become aware of their own thoughts, it also constantly changes the causal properties of these thoughts. In light of these empirical studies, mental representations appear to be intrinsically dependent on consciousness. This discovery represents an obstacle to any attempt to construct an artificial mind. (shrink)

Originating in the work of Ernst Haeckel and Wilhelm Preyer, and advanced by a Prussian embryologist, Wilhelm Roux, the idea of struggle for existence between body parts helped to establish a framework, in which population cell dynamics rather than a predefined harmony guides adaptive changes in an organism. Intended to provide a causal-mechanical view of functional adjustments in body parts, this framework was also embraced later by early pioneers of immunology to address the question of vaccine effectiveness and pathogen resistance. (...) As an extension of these early efforts, Elie Metchnikoff established an evolutionary vision of immunity, development, pathology, and senescence, in which phagocyte-driven selection and struggle promote adaptive changes in an organism. Despite its promising start, the idea of somatic evolution lost its appeal at the turn of the twentieth century giving way to a vision, in which an organism operates as a genetically uniform, harmonious entity.

Central to vaccination-induced responses, antibodies are suggested by Vaz to operate as observer-dependent entities that owe their status to categorization schemes of immunologists. Inspired by color research by Maturana, he argues that antibodies should be distinguished from immunoglobulins, which unlike the former can be considered as constituents of structural dynamics of an organism, products of millions of years of evolution. However, a deeper understanding of the historical roots of the concept of immunoglobulin and associated “languaging” and naming processes reveals that (...) immunoglobulins, as much as antibodies, are contingent on conceptual schemes of immunology.

To enable microbial colonisation of the gut mucosa, the intestinal immune system must not only react to danger signals but also recognize cues that indicate safety. Safety recognition, paradoxically, is mediated by the same environmental sensors that are involved in signalling danger. Indeed, in addition to their well established role in inducing inflammation in response to stress signals, pattern recognition receptors (PRRs) and a variety of metabolic sensors also promote gut-microbiota symbiosis by responding to "microbial symbiosis factors", "resolution-associated molecular patterns", (...) markers of energy extraction and other signals indicating the absence of pathogenic infection and tissue damage. Here we focus on how the paradoxical role of immune receptors and other environmental sensors define the microbiota signature of the individual. (shrink)

Commensal and pathogenic organisms employ camouflage and mimicry to mediate mutualistic interactions and predator escape. However, the immune mechanisms accounting for the establishment and maintenance of symbiotic bacterial populations are poorly understood. A promising hypothesis suggests that molecular mimicry, a condition in which different organisms share common antigens, is a mechanism of establishing tolerance between commensals and their hosts. On this view, certain bacteria may mimic the structural features of some of their host’s T-cell receptors (TCRs), namely those that survive (...) thymic selection due to their lack of complementarity to self-antigens. With such “holoimmunity” the mimicking micro-organisms avoid immune recognition as the copied TCRs become mirror images of an extended super-organismal self, consisting of symbiotic and host antigens. Accordingly, analysis of genomic and metagenomic data suggests a tripartite mimicry between TCRs, self-antigens, and commensal antigens that would serve as the basis for immune tolerance between these populations. And conversely, in an autoimmune scenario, both symbiotic microbes and the mimicked host tissue would be targeted for immune destruction. (shrink)

Coordination of immune responses in the gut is a complex task. In order to fight pathogens and maintain a defined population of commensal microbes, the mucosal immune system has to coordinate information from the external (luminal) and internal (abluminal) environment and respond accordingly. Dendritic cells (DCs) are crucial cell types involved in this process as they integrate these signals and direct immunogenic or tolerogenic responses. Here, we review how various functions of DCs depend on microbial stimuli and how these stimuli (...) influence the course of immune activation. (shrink)

One of the fundamental questions of life sciences is one of whether there are genuinely random biological processes. An affirmative or negative answer to this question may have important methodological consequences. It appears that a number of biological processes are explicitly classified as random. One of them is the so-called somatic hypermutation. However, closer analysis of somatic hypermutation reveals that it is not a genuinely random process. Somatic hypermutation is called random because the exact outcome of this process is difficult (...) to predict in practice. The case of somatic hypermutation suggests that there may be no scientific evidence of a single case of ontologically random process in the biological world. (shrink)

[Przekład] Pogląd głoszący, że układ odpornościowy rozróżnia to, co swoje, od tego, co obce, był jednym z centralnych założeń immunologii w drugiej połowie XX wieku. Pogląd ten miał wpływ na projekty eksperymentalne i interpretowanie danych. Jednakże w obliczu nowych dowodów empirycznych konieczny jest w immunologii nowy aparat konceptualny.

There is a deep-seated neopositivist view which regards the language of science as a neutral medium of communication, radically different from indirect symbolic forms of discourse characteristic of arts and humanities. But naturalists, like poets and social scientists, also draw on the dominant images in their culture to organize their thoughts and simplify complex concepts. By conceptualizing one thing in terms of another, metaphors in science not only aid mutual communication between researchers but also structure their understanding of experience and (...) reality. Too transparent to be noticed and critically analyzed within the framework of science itself, metaphors act as lenses, making selected aspects of complex phenomena visible to study and investigation (Reynolds 2018). By linking two seemingly unrelated ideas, for example, those of a machine and DNA replication, metaphors establish new interactions of meaning evoking shared associated connotations between these interacting concepts (Black 1962). This, in turn, may not only transform the perception of a target domain but also open up new prospects for experimental and interpretative avenues. Understanding Metaphors by Andrew Reynolds draws on this vision of metaphors as indispensable tools of scientific thinking to elucidate their role in the life sciences. (shrink)

Immunity by William Paul is an overview of fundamental principles of immunology and their experimental basis. The book includes not only well- established facts about the immune system but also recent findings (the role of Th17 cells, regulatory T cells, inflammasomes, etc.), which are skillfully incorporated into the framework of immunological understanding. The presentation is clear and emotionally charged, which makes the reading of Immunity enjoyable. Despite the original intentions, though, the book may appear too challenging for a lay reader (...) to serve as a popular introduction to immunology. Instead, it may help to put already acquired immunological knowledge in order benefiting advanced biology students and researchers. At a deeper level, Immunity provokes questions concerning what counts as relevant and what counts as a landmark in immunology. (shrink)

The fight to find effective, long-lasting treatments for cancer has led many researchers to consider protein degrading entities. Recent developments in PROteolysis TArgeting Chimeras (PROTACs) have signified their potential as possible cancer therapies. PROTACs are small molecule, protein degraders that function by hijacking the built-in Ubiquitin-Proteasome pathway. This review mainly focuses on the general design and functioning of PROTACs as well as current advancements in the development of PROTACs as anticancer therapies. Particular emphasis is given to PROTACs designed against various (...) types of Leukemia/Blood malignancies. (shrink)

The Metaphysics of Cooperation presents the intellectual achievements of the Polish associative socialist and pioneer of social sciences, Edward Abramowski. The volume is divided into five sections, each of them contains an analysis of Polish philosopher's work according to the issues he dealt with: sociology, ethics, politics, cooperativism, and psychology. Each part also contains a selection of his writings. Its intention is to show Abramowski's works in the context of global intellectual history and to include them in the current political (...) debates. Abramowski makes fraternity or cooperation the main concepts of his social metaphysics. The Polish version of cooperativism can be inspiring both for contemporary researchers and political activists in the post-economic-crisis Europe. It also opens up a space for creating more democratic political and economic institutions. (shrink)

The following article challenges the traditional reading of the Rural Dionysia scene in Aristophanes’ Acharnians. It is often assumed that the text contains a reference to an animal sacrifice, which is arguably absent from this comedy. Moreover, the vast majority of scholars claim that the lines 244 ff. were uttered after the procession of worshippers reached the altar in the orchestra. However, as I argue, these verses were most probably spoken by the characters in front of the door of the (...) comic hero’s house and only subsequently did the procession form and move towards the altar.

Having been involved in a slew of recent scandals, many of the world’s largest technology companies embarked on devising numerous codes of ethics, intended to promote improved standards in the conduct of their business. These efforts have attracted largely critical interdisciplinary academic attention. The critics have identified the voluntary character of the industry ethics codes as among the main obstacles to their efficacy. This is because individual industry leaders and employees, flawed human beings that they are, cannot be relied on (...) voluntarily to conform with what justice demands, especially when faced with powerful incentives to pursue their own self-interest instead. Consequently, the critics have recommended a suite of laws and regulations to force the tech companies to better comply with the requirements of justice. At the same time, they have paid little attention to the possibility that individuals acting within the political context, e.g. as lawmakers and regulators, are also imperfect and need not be wholly compliant with what justice demands. This paper argues that such an omission is far from trivial. It creates a heavy argumentative burden on the part of the critics that they by and large fail to discharge. As a result, the case for Big Tech regulation that emerges from the recent literature has substantial lacunae and more work needs to be done before we can accept the critics’ calls for greater state involvement in the industry.

Is it wrong to distract? Is it wrong to direct others’ attention in ways they otherwise would not choose? If so, what are the grounds of this wrong – and, in expounding them, do we have to at once condemn large chunks of contemporary digital commerce (also known as the attention economy)? In what follows, I attempt to cast light on these questions. Specifically, I argue – following the pioneering work of Jasper Tran and Anuj Puri – that there is (...) a right to attention, and that its existence underlies some of our claims regarding the wrongness of distractions. However, I depart from both these authors in two respects: first, I present a new way of deriving the right to attention, grounding it in the more fundamental right to mental integrity. Second, I remain agnostic on whether the contemporary business practices of capturing attention in exchange for a variety of digital products and services are plagued by routine violations of the right.

Abstract:Non-anthropocentric approaches to environmental ethics face problems that cannot be resolved within a holistic framework of natural value since such frameworks posit abstract and general properties as the bearers of intrinsic value and thus ignore the moral claims of individual organisms. Two paradigm examples of such approaches, Aldo Leopold's Land Ethic and Arne Neass' Deep Ecology suffer from this problem. Christine Korsgaard's argument for the conceptual separation of intrinsic and instrumental valuing, however, serves as a strong theoretical grounding for a (...) reconceptualization of the value of nature, which can best be described as an enlightened anthropocentrism, while preserving the spirit of Leopold's and Naess' proposals.

David Lewis cautions that although a no-collapse interpretation of quantum mechanics entails immortality for trans-world selves, the nature of the branching leaves us crippled, lonely, deathly ill, and mentally infirm, meaning that immortal life, on such terms, amounts to an existence in eternal torment. This paper argues that the problem Lewis points to is in fact one of individuation and that a synthesis of Lewis’ own notion of perdurance and Robert Nozick’s closest continuer theory, when cast in the mould of (...) a deterministic multiverse, individuates trans-world selves in such a way as to allow to prune the infinitesimal expectation of a miserable eternal existence from the histories of most trans-world agents. Thus, contrary to Lewis’ warning that if personal identity is a trans-world notion, then we should all shake in our shoes, this paper argues that even if we are trans-world selves, we almost certainly have nothing to worry about.

This paper offers a critical review of the notion of a “singular cognitive role”, which is central to some recent theories of singular thought. According to those theories, whether a thought is singular depends on the role it plays in the subject’s cognitive activity. We compare the two most developed accounts of this type: Crane’s :21–43 2011, The Objects of Thought2013) and Jeshion’s. Both theories aim to capture the notion of a singular cognitive role in terms of mental files. We (...) argue that Jeshion’s theory is much more promising as it provides a more detailed and non-circular characterization of the mental files responsible for singular thinking. We examine the prospects for enhancing that account in light of three major concerns about it present in the literature. First, we discuss whether the weakest aspect of the whole proposal, i.e. the condition for the initiation of mental files, can be replaced without debilitating the rest of the theory. Second, we examine Goodman’s : 437–461 2014, The Philosophical Quarterly2015) argument against mental file theories of singular thought and show that it does not affect Jeshion’s account. Third, we argue against Sawyer :264–283 2012) that Jeshion’s notion of a singular cognitive role is in strong opposition to acquaintance-based theories of singular thought and cannot be incorporated into any of them. Thus, the paper concludes that Jeshion’s proposal, despite its shortcomings, is currently the most promising account of a singular cognitive role. (shrink)

Arne Neass’ Ecosophy and the Stoic attitude towards environmental ethics are often believed to be incompatible primarily because the first is often understood as championing an ecocentric standpoint while the latter espouses an egocentric (as well as an anthropocentric) view. This paper argues that such incompatibility is rooted in a misunderstanding of both Ecosophy and Stoicism. Moreover, the paper argues that a synthesis of both the Ecosophical and Stoic approaches to environmental concerns results in a robust and satisfying attitude toward (...) the environment, namely an enlightened self-interest, which not only guards our fragile environment from abuse, but also provides self-interested reasons and motivations for the protection of our natural surroundings.

This paper argues, against the prevailing view, that consent to privacy policies that regular internet users usually give is largely unproblematic from the moral point of view. To substantiate this claim, we rely on the idea of the right not to know (RNTK), as developed by bioethicists. Defenders of the RNTK in bioethical literature on informed consent claim that patients generally have the right to refuse medically relevant information. In this article we extend the application of the RNTK to online (...) privacy. We then argue that if internet users can be thought of as exercising their RNTK before consenting to privacy policies, their consent ought to be considered free of the standard charges leveled against it by critics.

This Dissertation argues for a care-centrically grounded account of relational personhood and widely realized diachronic personal identity. The moral distinction between persons and non-persons is arguably one of the most salient ethical lines we can draw since many of our most fundamental rights are delineated via the bounds of personhood. The problem with drawing such morally salient lines is that the orthodox, rationalistic definition of personhood, which is widespread within philosophical, medical, and colloquial spheres, excludes, and thereby de-personifies, a large (...) number and a great variety of human beings such as neonates, young children, the elderly who suffer from dementia, individuals with severe cognitive disabilities, and patients in vegetative states. The reconceptualization of personhood necessary for a more inclusive definition ought to originate with an appropriate moral grounding. To this end, this Dissertation grounds the notion of personhood in the care ethical sphere, thereby emphasizing the role of care relations in the maintenance of the moral consideration of vulnerable individuals. This Dissertation argues that grounding the concept of a person in care relations entails a relational account of personhood, which, along with the insights of the Extended Mind and Social Manifestation Theses, leads to an extended and externalized understanding of diachronic identity, which allows fragile people to be held in their personal identities even if they themselves lack the capacities usually associated with moral personhood. As we trace a person’s identity through time, we track the various relational properties, which constitute personal narratives and thus act as a glue that binds such dynamic and often unique properties into stable, trackable narratives. Since care relations are morally relevant on a care-centric account of personhood, what is lost in cases where such care relating ceases is not merely of sentimental value, but of great moral importance as well. Morally meaningful care relations are not replaceable, and, by extension, neither are the narratives that are constituted by such unique and irreplaceable instances of relating. This Dissertation argues that the constitutive care relational nature of personal narratives makes such narratives irreplaceable and is precisely what makes persons so morally precious. (shrink)

Abstractabstract:The aim of this article is to analyze the close relation between social theory (“sociological phenomenalism”) and the political ideology of the Polish thinker Edward Abramowski. Abramowski’s “applied sociology” involved: (1) the sociology of “fraternity,” examining basic forms of socialization; (2) combining social revolution with ethical self-improvement; and (3) the dissemination of “social laboratories” through the development of a network of cooperatives. As “experiments of the will,” the cooperatives allowed Abramowski to combine science, imagination, and ethics in a coherent project (...) of political utopia-building, extending the possible forms of community. Finally, the article shows that in Abramowski’s case, the meaning of utopia as an element embedded in a wide range of political practices derives from his vision of social science. Due to the influence that Abramowski’s thought had on political reality in Poland, the concept of “experimental” utopia entered the vocabulary of modern social sciences in Poland for good. (shrink)

David Lewis’ contemplations regarding divine foreknowledge and free will, along with some of his other more substantial work on modal realism and his counterpart theory can serve as a springboard to a novel solution to the foreknowledge and metaphysical freedom puzzle, namely a proposal that genuine metaphysical freedom is compatible with determinism, which is quite different from the usual compatibilist focus on the compatibility between determinism and moral responsibility. This paper argues that while Lewis opens the doors to such a (...) possibility, in order to fully elucidate a genuinely metaphysical compatibilist account, Lewis’ own counterpart theory must be abandoned in favour of an account of trans-world identity that is theoretically framed by a modified version of Robert Nozick’s closest continuer theory.
