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)

Immunology is central to contemporary biology and medicine, but it also provides novel philosophical insights. Its most significant contribution to philosophy concerns the understanding of biological individuality: what a biological individual is, what makes it unique, how its boundaries are established and what ensures its identity through time. Immunology also offers answers to some of the most interesting philosophical questions. What is the definition of life? How are bodily systems delineated? How do the mind and the body (...) interact? In this Element, Thomas Pradeu considers the ways in which immunology can shed light on these and other important philosophical issues. This title is also available as Open Access on Cambridge Core.

We analyse the effect of the regulatory T cells (Tregs) in the local control of the immune responses by T cells. We obtain an explicit formula for the level of antigenic stimulation of T cells as a function of the concentration of T cells and the parameters of the model. The relation between the concentration of the T cells and the antigenic stimulation of T cells is an hysteresis, that is unfold for some parameter values. We study the appearance of (...) autoimmunity from cross-reactivity between a pathogen and a self antigen or from bystander proliferation. We also study an asymmetry in the death rates. With this asymmetry we show that the antigenic stimulation of the Tregs is able to control locally the population size of Tregs. Other effects of this asymmetry are a faster immune response and an improvement in the simulations of the bystander proliferation. The rate of variation of the levels of antigenic stimulation determines if the outcome is an immune response or if Tregs are able to maintain control due to the presence of a transcritical bifurcation for some tuning between the antigenic stimuli of T cells and Tregs. This behavior is explained by the presence of a transcritical bifurcation. (shrink)

During the past thirty years, immunological metaphors, motifs, and models have come to shape much social theory and philosophy. Immunology, so it seems, often has served to naturalize claims about self, identity, and sovereignty—perhaps most prominently in Jacques Derrida’s later studies. Yet the immunological science that functions as “nature” in these social and philosophical arguments is derived from interwar and Cold War social theory and philosophy. Theoretical immunologists and social theorists knowingly participated in a common culture. Thus (...) the “naturalistic fallacy” in this case might be reframed as an error of categorization: its conditions of possibility would require ceaseless effort to purify and separate out the categories of nature and culture. The problem—inasmuch as there is a problem—therefore is not so much the making of an appeal to nature as assuming privileged access to an independent, sovereign category called “nature.”. (shrink)

In this fascinating and inventive work, A. David Napier argues that the central assumption of immunology—that we survive through the recognition and elimination of non-self—has become a defining concept of the modern age. Tracing this immunological understanding of self and other through an incredibly diverse array of venues, from medical research to legal and military strategies and the electronic revolution, Napier shows how this defensive way of looking at the world not only destroys diversity but also eliminates the possibility (...) of truly engaging difference, thereby impoverishing our culture and foreclosing tremendous opportunities for personal growth. To illustrate these destructive consequences, Napier likens the current craze for embracing diversity and the use of politically correct speech to a cultural potluck to which we each bring different dishes, but at which no one can eat unless they abide by the same rules. Similarly, loaning money to developing nations serves as a tool both to make the peoples in those nations more like us and to maintain them in the nonthreatening status of distant dependents. To break free of the resulting downward spiral of homogenization and self-focus, Napier suggests that we instead adopt a new defining concept based on embryology, in which development and self-growth take place through a process of incorporation and transformation. In this effort he suggests that we have much to learn from non-Western peoples, such as the Balinese, whose ritual practices require them to take on the considerable risk of injecting into their selves the potential dangers of otherness—and in so doing ultimately strengthen themselves as well as their society. _The Age of Immunology,_ with its combination of philosophy, history, and cultural inquiry, will be seen as a manifesto for a new age and a new way of thinking about the world and our place in it.

A survey of models in immunology is conducted and distinct kinds of models are characterized based on whether models are material or conceptual, the distinctiveness of their epistemic purpose, and the criteria for evaluating the goodness of a model relative to its intended purpose. I argue that the diversity of models in interdisciplinary fields such as immunology reflects the fact that information about the phenomena of interest is gathered from different sources using multiple methods of investigation. To each (...) model is attached a description specifying how information about a phenomenon of interest has been acquired, highlighting points of commonality and difference between the methodological and epistemic histories of the information encapsulated in different models. These points of commonality and difference allow investigators to integrate findings from different models into more comprehensive explanatory accounts, as well as to troubleshoot anomalies and faulty accounts by going back to the original building blocks.

Introduction to the Philosophy of Science: Cutting Nature at Its Seams is a clear and lively explanation of key concepts and issues in the philosophy of science. It surveys the field from positivism to social constructivism, focusing on the metaphysical implications of science as a form of knowledge gathering that explains what the world is really like, while simultaneously arguing for the superiority of a holistic model of scientific theories over competing models. An innovative feature is the use (...) of immunology as the central domain of illustration, in contrast to other philosophy of science texts that draw examples predominantly from physics. The text also presents Thomas Kuhn's model of science clearly and accurately, rectifying the notorious and widespread misinterpretations projected upon it in the past. Klee discusses both traditional models of science and alternative interpretations, most notably nonfeminist and feminist models inspired by the work of Kuhn. Richly illustrated and complete with a glossary of over eighty key terms, this book serves as an ideal text for undergraduates, because it presents a highly accessible and contemporary investigation of science as a form of inquiry capable of revealing to us the structure of the world.

Throughout his career, the problems that attracted Louis Pasteur almost invariably involved considerations of specificity of structure and/or of action. Thus, his work on asymmetric crystals showed that chemical form not only specifies crystalline structure, but affects the affinity of ferments as well. In his studies of diseases of silkworms, of beer, and of wine, he could unerringly distinguish with the microscope the specific agents of disease. From this emerged his concept of the specificity of species and against the nonspecificity (...) of spontaneous generation, whence the germ theory of disease. It was in the new field of immunology, however, where the manifestations of an exquisite specificity were most clearly seen. Here, Pasteur's vaccines worked because he chose the specific pathogen in order to induce a specific immunity, and he succeeded each time. But the two most prominent Pastorian successors in immunology, Elie Metchnikoff and Jules Bordet, were not equally successful. Although each contributed significantly to the birth of immunology, each advanced a theory that neglected the principle of specificity and paid a price in consequence. Metchnikoff's phagocytic theory of immunity could not survive the demonstrable specificity of humoral antibodies, while Bordet's physical adsorptive concept of the antibody-cell interaction quickly fell to Paul Ehrlich's demonstration of the stereochemical determination of immunological specificity.

How does one testify and, moreover, testify philosophically to the experience of receiving an organ transplant? What kinds of survival or forms of living are being fostered by newly emerging conjunctions between philosophy and biomedicine? Focusing on transplantation and immunology, we are going to reflect on some of the ways and styles in which motifs drawn from these biomedical fields have come to occupy an increasingly prominent place in recent philosophy expressing and formulating different concerns and paradigms. (...) Spurred on by Francisco J. Varela and Jean-Luc Nancy's autobiographical reflections on transplantation, we are going to consider distinct moments and preoccupations at work in the motifs of immunity, autoimmunity, the pharmakon and the graft in the thought of Jacques Derrida, Roberto Esposito and Bernard Stiegler.

An allergy is commonly understood to be an overreaction of the immune system to harmless substances that are misrecognised as foreign. This concept of allergy as an abnormal, misdirected immune response—a biological fault—stems from the idea that the immune system is an inherently defensive operation designed to protect the individual through an innate capacity to discriminate between the benign and toxic, or self and nonself. However, this definition of allergy represents a radical departure from its original formulation. Literally meaning ‘altered (...) reactivity’, the term was coined in 1906 by Austrian paediatrician Clemens von Pirquet, to describe the fundamentally mutable nature of the immune response.This paper argues that the conventional interpretation of allergy-as-pathology derives from specific concepts of ‘organism’, ‘response’, and ‘normal’ immune function that have—for over a century—governed the perception and study of immune phenomena within immunology. Through an examination of Louis Pasteur’s conceptualisation of the host body/microorganism relationship, I argue that immunology is founded on a view of the organism as a discrete, autonomous entity, and on a concomitant notion of the immune response as essentially reactive. Revisiting the concept of ‘altered reactivity’, this paper points to the fact that allergy was initially posited as a general theory of immune responsiveness and, importantly, one that poses a significant challenge to orthodox notions of immunopathology. It suggests that Pirquet’s unique view of immune responsiveness presents an account of organismic or biological identity that encapsulates, rather than reduces, its ecological complexity. (shrink)

Comparative political theory is at best an embryonic and marginalized endeavor. As practiced in most Western universities, the study of political theory generally involves a rehearsal of the canon of Western political thought from Plato to Marx. Only rarely are practitioners of political thought willing (and professionally encouraged) to transgress the canon and thereby the cultural boundaries of North America and Europe in the direction of genuine comparative investigation. Border Crossings presents an effort to remedy this situation, fully launching a (...) new era in political theory. Thirteen scholars from around the world examine the various political traditions of West, South, and East Asia and engage in a reflective cross-cultural discussion that belies the assumptions of an Asian "essence" and of an unbridgeable gulf between West and non-West. The denial of essential differences does not, however, amount to an endorsement of essential sameness. As viewed and as practiced by contributors to this ground-breaking volume, comparative political theorizing must steer a course between uniformity and radical separation--this is the path of "border crossings.".

Discovery proceeds in stages of construction, evaluation, and revision. Each of these stages is constrained by what is known or conjectured about what is being discovered. A new characterization of mechanism aids in specifying what is to be discovered when a mechanism is sought. Guidance in discovering mechanisms may be provided by the reasoning strategies of schema instantiation, modular subassembly, and forward/backward chaining. Examples are found in mechanisms in molecular biology, biochemistry, immunology, and evolutionary biology.

What counts as an individual in the living world? What does it mean for a living thing to remain the same through time, while constantly changing? Immunology answers these questions with its theory of "self" and "nonself" which has dominated the field since the 1940s. Thomas Pradeu argues that this theory is inadequate, because immune responses to self constituents and immune tolerance of foreign entities are the rule, not the exception.

Contemporary immunology has established its fundamental theory as a biological expression of personal identity, wherein the "immune self" is defended by the immune system. Protection of this agent putatively requires a cognitive capacity by which the self and the foreign are perceived and thereby discriminated; from such information, discernment of the environment is achieved and activation of pathways leading to an immune response may be initiated. This so-called cognitive paradigm embeds such functions as "perception," "recognition," "learning," and "memory" to (...) characterize immune processes, but the conceptual character of such functions has meanings that vary with the particular theory adopted. When different formulations of cognition are considered, immunology's conceptual infrastructure shifts: Extensions of conventional psychological understanding of representational cognition based on a subject-object dichotomy support notions of immune agency; alternatively, formulations of perception that dispense with representations and attendant notions of agency reconfigure the predicate epistemology dominating current immune theory. Reviewing immunological literature of the past five decades, these two understandings of perception – representational and non-representational – offer competing views of immune cognitive functions. These, in turn, provide competing philosophical understandings of immunology's conceptual foundations, which reflect parallel controversies dominating current debates in philosophy of mind and attendant discussions about personal identity.

The Limits of the Self, will be essential reading for anyone interested in the definition of biological individuality and the understanding of the immune system.

Philosophical understanding of experimental scientific practice is impeded by disciplinary differences, notably that between philosophy and sociology of science. Severing the two limits the stock of philosophical case studies to narrowly circumscribed experimental episodes, centered on individual scientists or technologies. The complex relations between scientists and society that permeate experimental research are left unexamined. In consequence, experimental fields rich in social interactions have received only patchy attention from philosophers of science. This paper sketches a remedy for both the symptom (...) and its root cause. An empirical study of social interactions in an established field of biomedicine grounds a robust account of success in experimental practice. The core idea is the concept of collaboration, of participants working together on a common project toward a shared goal. The interactive social integument of experimental research is both examined and enacted in a study integrating socio-historical research and philosophical investigation. The two approaches are used in concert to explicate the concept of scientific objectivity. Their joint explication of this contested epistemic ideal demonstrates that philosophical and sociological approaches can work together toward a social epistemology of scientific practice. The explication is in three stages. First, a minimal framework for investigating collaborative activities is established. Social action is understood and evaluated in terms of the connection between shared goals that participants hope to accomplish together, and the coordinated means by which they try to do so. This connection is explicated as participation, a relation mediating between a group and its members, which includes minimal constraints of instrumental rationality. Second, this framework is fleshed out via empirical study of scientific practices. The focal case examines the intersection of immunology and stem cell research in mid-20th century biomedicine, tracing the key social interactions within and among laboratory groups, as the field of blood stem cell research emerged in the 1960s and advanced throughout the next four decades. The study yields a robust empirical result. Participants consistently recognize two aspects of scientific success: construction of improved models of blood cell development, and formation of new boundaries among scientific groups. In the third and final stage, this result is generalized to other experimental episodes and shown to fit with recent accounts of models in scientific practice. The generalized result approximates a familiar normative view of scientific knowledge. An epistemic ideal of scientific objectivity in practice is then derived from this robust general result, using the minimal constraints on rational participation. The derivation is analogous to specification of ends in moral philosophy; given the means taken and assuming some hope of success, what must the goal of scientific inquiry be like? The aim of science so conceived corresponds to a classic conception of scientific objectivity: knowledge independent of epistemic criteria specific to particular persons or groups. This result weaves together sociological and philosophical accounts of science, explicating the epistemic ideal of objectivity in relation to social aspects of scientific practice. This undercuts the entrenched dualism between normative, vs. descriptive approaches to scientific knowledge. Socio-historical study of science does not deflate, but vindicates, scientific objectivity. Philosophy and sociology are recast as collaborating participants in articulating social epistemology of science. (shrink)

Thomas Pradeu’s The Limits of the Self provides a precise account of biological identity developed from the central concepts of immunology. Yet the central concepts most relevant to this task are themselves deemed inadequate, suffering from ambiguity and imprecision. Pradeu seeks to remedy this by proposing a new guiding theory for immunology, the continuity theory. From this, an account of biological identity is provided in terms of uniqueness and individuality, ultimately leading to a defense of the heterogeneous organism (...) as expressing the highest degree of individuality.

According to a widely held view, scientific modelling consists in entertaining a set of model descriptions that specify a model. Rather than studying the phenomenon of interest directly, scientists investigate the phenomenon indirectly via a model in the hope of learning about some of the phenomenon’s features. I call this view the description-driven modelling (DDM) account. I argue that although an accurate description of much of scientific research, the DDM account is found wanting as regards the mechanistic modelling found in (...) many branches of biology. By analysing research practices in cancer immunology concerning the development of mechanistic models of the process of cancer metastasis, this paper presents and argues for a complementary account of scientific modelling, herein called the experimentation-driven modelling (EDM) account. In EDM, scientists investigate a set of experimental systems and then integrate the results obtained from experiments into a mechanistic model. While EDM shares some key features with DDM, the two are epistemically very different approaches to research. (shrink)

In ancient philosophy life has priority: non-living matter is made intelligible by living activity. The modern evolutionary synthesis reverses this priority: life is a passive result of blind, non-living material processes. But recent work in science and philosophy puts that reversal in question, by emphasizing how living beings are self-organizing and active. “Naturalizing” this new emphasis on living activity requires not simply a return to ancient philosophy but a new ontology, a new concept of nature. To explore (...) that ontology, I draw on Merleau-Ponty’s philosophy, studying the link between the organism and its environment, the body and the world, as reflecting a nature in which things are already linked in a moving whole. I focus on the topics of expression and movement, putting Merleau-Ponty into conversation with recent discussions in philosophy of science, especially in immunology and in evolutionary theory, and attending to Bergsonian and Hegelian threads in the background of Merleau-Ponty’s thinking.

The self/non-self model, first proposed by F.M. Burnet, has dominated immunology for 60 years now. According to this model, any foreign element will trigger an immune reaction in an organism, whereas endogenous elements will not, in normal circumstances, induce an immune reaction. In this paper we show that the self/non-self model is no longer an appropriate explanation of experimental data in immunology, and that this inadequacy may be rooted in an excessively strong metaphysical conception of biological identity. We (...) suggest that another hypothesis, one based on the notion of continuity, gives a better account of immune phenomena. Finally, we underscore the mapping between this metaphysical deflation from self to continuity in immunology and the philosophical debate between substantialism and empiricism about identity.

Biological self reference idioms in brain-centered or nervous-system-centered self determination of the consious Self reveal an interesting contrast with biological self-determination by immunological self/non-self discrimination. This contrast is both biological and epistemological. In contrast to the consciousness conscious of itself, the immunological self-determination imposes a protective mechanism against self-recognition (Coutinho et al. 1984), which adds to a largely unconscious achievement of the biological Self (Popper 1977; Medawar 1959). The latter viewpoint is in contrast with the immunological Self-determination as an essentially (...) cognitive process as expressed in the analysis of Tauber (1994). Comparison of the immune system in vertebrates and invertebrates, according to new biological insights, has contributed to a better understanding of the relative role of innate (or inherited) immunity versus immunity acquired during each individual life. Also in this respect, immunological self-achievement shows both a striking analogy and a fundamental discrepancy with the activity of the nervous system. The analysis of immunological Self/non-self discrimination versus brain-centered self-determination adds to the understanding of the function paradigm in biological self-reference idioms, especially when regarding the importance of the connectivity notion in both systems. Adopting functional explanatory schemes for understanding immunological self-non-self discrimination, as well as for the understanding of functional mapping of the brain at (conscious) activity (Friston et al. 1993; Frith et al. 1995), forwards the notion of effective/functional connectivity. Network connectivity not only is a primary question in solving the dimensionality question for immunological ‘idiotypic networks’ (Jerne 1974a, b; 1984), it may also have an important value in describing phase transitions in the development of both immune and nervous systems.

Immunology is a notoriously complex field with distinct concepts and terminology. Yet immunologists regularly and effectively collaborate with other researchers, notably clinicians and experts in population health. How does such ‘collaboration without convergence’ work? This paper offers an answer. Immunology exhibits three features that support collaboration in the absence of major consensus on theories, methods, or concepts. These are: a multifaceted target of inquiry, therapeutic aspirations, and a clear interdisciplinary pathway. Building on these features, I sketch a general (...) account of “low-effort interdisciplinarity” and connect this result to recent work on population health. (shrink)

In the postgenomic era, interactions between organism and environment are central in disciplines such as epigenetics, medical physiology, and immunology. Particularly in the more "applied" medical fields, an emphasis lies on interactions of the organism with other organisms, that is, other living things. There is, however, a growing amount of research investigating the impact of abiotic triggers on the immune system. While the distinction between biota and abiota features heavily in other contexts, its status is not explicit within (...) class='Hi'>immunology. Do immunologists distinguish living from nonliving triggers? In this article, I will carve out whether and in which ways the biotic/abiotic distinction operates in immunology. I will look into responses to biotic and abiotic stressors in plant and invertebrate model species and ask how and why they are conceptually separated. I will trace the reasons by investigating the disciplinary situatedness of immune phenomena and the import of vertebrate immunology when conceptualizing immune responses in other model organisms. I will then investigate how the convergence of biotic and abiotic stress responses in plants and invertebrates adds to the recent philosophical programs advocating an ecological perspective on immune systems.

The traditional conception of immune function is that of a system which differentiates the organism’s own tissues (the self) from any foreign invaders (nonself), preserving the former by rejecting the latter. In a mammalian pregnancy, however, the immunologically foreign foetus is accepted by the gestator’s immune system. This presents a serious challenge to the self–nonself theory which has sometimes been called the immunological paradox of pregnancy. In this paper I shall defend the self–nonself theory against the critique posed by Thomas (...) Pradeu. In addition I critically examine the alternative he proposes—the continuity theory. The main problem I will raise for any theory of immunology is that the phenomenon to be explained in pregnancy is the non-rejection of the foetus despite the triggering of the gestator’s immune system. I will argue that contemporary modified versions of the self–nonself theory can rise to this challenge but that continuity theory cannot. As such, the immunology of pregnancy gives us a good reason to favour contemporary self–nonself theory over the continuity theory. (shrink)

Did Chinese mysticism vanish after its first appearance in ancient Taoist philosophy, to surface only after a thousand years had passed, when the Chinese had adapted Buddhism to their own culture? This first integrated survey of the mystical dimension of Taoism disputes the commonly accepted idea of such a hiatus. Covering the period from the Daode jing to the end of the Tang, Livia Kohn reveals an often misunderstood Chinese mystical tradition that continued through the ages. Influenced by but (...) ultimately independent of Buddhism, it took forms more various than the quietistic withdrawal of Laozi or the sudden enlightenment of the Chan Buddhists. On the basis of a new theoretical evaluation of mysticism, this study analyzes the relationship between philosophical and religious Taoism and between Buddhism and the native Chinese tradition. Kohn shows how the quietistic and socially oriented Daode jing was combined with the ecstatic and individualistic mysticism of the Zhuangzi, with immortality beliefs and practices, and with Buddhist insight meditation, mind analysis, and doctrines of karma and retribution. She goes on to demonstrate that Chinese mysticism, a complex synthesis by the late Six Dynasties, reached its zenith in the Tang, laying the foundations for later developments in the Song traditions of Inner Alchemy, Chan Buddhism, and Neo-Confucianism.
