For Vajrayana Buddhism, the now is an interval, a boundary, a point of tension and suspension with an atmosphere of uncertainty. It is a bifurcation point of variable length; its name is “bardo.” The bardo is immersed in the conventional, or “seeming” reality. It emerges from what is called the “unstained” ultimate or primordial emptiness or “basal clear light.” Further, the ultimate is not the sphere of cognition. Cognition, including cognition of time, belongs to conventional reality. Buddhahood, in contrast, is (...) a condition of uncompounded knowledge where basic mind blossoms without temporal or other cognitive distinctions, unmade, unfabricated, luminous and pristine. Cyclical existence involves both the ultimate and the conventional as it moves through six bardos—all of which are the effulgent of the basal clear light—until Buddhahood. The six are: the bardo of this life ; the bardo of dream; the bardo of meditation; the bardo of dying; the bardo of dharmata ; and the bardo of existence. Each realm is both ultimate and conventional, and has specific initiation-based yogas to investigate these differences. The process of transition from one to the next involves at least three bodies, one mind, and aspects of speech. In each bardo, the character of the now as embodiment and temporal knowing varies yet a complete and consistent cross-bardo yogic wisdom leads to its total cessation in the basal clear light; the now is extinguished. The author presents, from the viewpoint of a knowledgeable practitioner of over 30 years, an essay on Vajrayana Buddhist time, drawing implications for Fraser’s time typology. The essay will draw from English translations of significant older, tantric texts on dream yoga, deity yoga, the Chod, tantric time, the bardo of death, and empowerment. Useful practices that can be applied by the audience to test the tradition and author’s assertions will be suggested. (shrink)

Many explanations in molecular biology, neuroscience, and other fields of experimental biology describe mechanisms underlying phenomena of interest. These mechanistic explanations account for higher-level phenomena in terms of causally active parts and their spatiotemporal organization. What makes such a mechanistic description explanatory? The best-developed answer, Craver's causal-mechanical account, has several weaknesses. It does not fully explicate the target of explanation, interlevel relation, or interactive nonmodular character of many biological mechanisms as we understand them. An alternative account of MEx, emphasizing interdependence (...) among a mechanism's components, remedies these difficulties. (shrink)

Following Talia Mae Bettcher, many philosophers distinguish between ethical and epistemic conceptions of the first-person authority that we have over our gender identities. Rather than construing this authority as explained by our superior epistemic access to our own gender identities, many have argued that we should view this authority as explained by ethical obligations that we have towards others. But such views remain silent on what we ought to believe about others’ gender identities: when someone avows their gender identity, should (...) we believe them? Or is it enough to merely act as though we do? In this paper, I argue that mere action is not enough: we ought to believe what others say about their gender identities. I present several cases that motivate the claim that there is something distinctively wrong with merely ‘playing along’ with what another person says about their gender identity. I offer several answers for what explains why such cases involve wrongs. I argue that an adequate account of FPA cannot remain silent on belief but must instead take on an epistemic norm of FPA in addition to an ethical norm of FPA. (shrink)

According to the dispositional account of gender, to have a gender is to have some set of behavioral dispositions. Robin Dembroff (2020) levels a strong objection to Jennifer McKitrick’s (2015) dispositional view of gender, arguing that it can neither capture the extension of genderqueer identities nor treat them with the respect that they warrant. In this paper, I offer a defense of the dispositional view against these charges. I argue that accounts of dispositions tailored to deal with masks and finks—phenomena (...) that would prevent a disposition from manifesting or change a disposition if it were about to manifest—can avoid Dembroff’s extensional worry without reducing nonbinary identities to a matter of mere linguistic convention. I offer a revision to the dispositional account of genderqueer that incorporates Dembroff’s insights about the nature of destabilizing gender binaries. (shrink)

Dispositions can be masked: some state of affairs might obtain which would prevent an entity from displaying the manifestation characteristic of its disposition. Yet discussions of masks overlook a number of key problems, chief among them the probabilistic nature of many dispositional masks. In this paper, I highlight the manner in which past analyses of dispositional masks have been unable to solve the problem of masks. I propose an analysis of dispositional masks which focuses on this and a number of (...) other problems, which I argue can address them better than past accounts can. I argue that some entity masks some disposition just in case that entity makes it such that the disposition is less likely to manifest, or such that it will manifest to a lower degree. (shrink)

Evolutionary systems biology (ESB) aims to integrate methods from systems biology and evolutionary biology to go beyond the current limitations in both fields. This article clarifies some conceptual difficulties of this integration project, and shows how they can be overcome. The main challenge we consider involves the integration of evolutionary biology with developmental dynamics, illustrated with two examples. First, we examine historical tensions between efforts to define general evolutionary principles and articulation of detailed mechanistic explanations of specific traits. Next, these (...) tensions are further clarified by considering a recent case from another field focused on developmental dynamics: stem cell biology. In the stem cell case, incompatible explanatory aims block integration. Experimental approaches aim at mechanistic explanation while dynamical system models offer explanation in terms of general principles. We then discuss an ESB case in which integration succeeds: search for general attractors using a dynamical systems framework synergizes with the experimental search for detailed mechanisms. Contrasts between the positive and negative cases suggest general lessons for achieving an integrated understanding of developmental and evolutionary dynamics. The key integrative move is to acknowledge two complementary aims, both relevant to explanation: identifying the space of possible dynamic states and trajectories, and mechanistic understanding of causal interactions underlying a specific phenomenon of interest. These two aims can support one another in a joint project characterizing dynamic aspects of evolving lineages. This more inclusive project can lead to insights that cannot be reached by either approach in isolation. (shrink)

The influence of Michael Polanyi on William H. Poteat’s teaching from 1967 to 1976 was apparent but not paramount. Cultural conceptual analysis as taught and practiced by Poteat during this period included Polanyian texts, themes, and concepts, but drew extensively from other major conceptual innovators who provided radical alternatives to key cultural conceptual commitments of modernity. This was the period roughly between the completion of Intellect and Hope and the writing of Polanyian Meditations.

In this chapter we will argue that the capacities necessary to moral and legal agency can be understood as executive functions in the brain. Executive functions underwrite both the cognitive and volitional capacities that give agents a fair opportunity to avoid wrongdoing: to recognize their acts as immoral and/or illegal, and to act or refrain from acting based upon this recognition. When a person’s mental illness is serious enough to cause severe disruption of executive functions, she is very likely to (...) lack substantial capacities necessary to be law-abiding. Our analysis supports the Model Penal Code test for legal insanity over the traditional M’Naghten test, because the Model Penal Code test allows either severely diminished cognitive or volitional capacities to warrant an excuse to criminal culpability. We will provide a nuanced account of the ways in which mental illness can erode executive function, as well as an explanation as to why severe diminishment of executive functions caused by mental illness, but not some other causes, is exculpatory.

Abstract The market is sometimes thought to be a largely neutral means for coordinating cooperation among strangers under complex conditions because it is, as Hayek noted, a ?spontaneous order.? But in fact the market actively shapes the kinds of values it rewards, as do other spontaneous orders. Recognizing these biases allows us to see how such orders impinge on one another and on other communities basic to human life, sometimes negatively. In this way we may come to acknowledge the inevitability (...) of placing limits on spontaneous orders. (shrink)

Thomas Spragens attempts to rebuild liberal theory by arguing that realist, libertarian, egalitarian, and identity liberals all have valid insights, but develop them one‐sidedly. Re‐examining the work of sixteenth‐ and seventeenth‐century liberals leads, he contends, to a more balanced liberalism. Spragens's often‐impressive effort to reconstruct liberalism is undermined by insufficient appreciation of the role of the scale of the polity and by confusions about civic friendship. Appreciation of Hayekian insights about spontaneous order, and of the limits of citizen knowledge in (...) large polities, would help him solve the first problem. Distinguishing between friendship, friendliness, and social capital would help resolve the second. (shrink)

In this paper we attempt to reply to the thoughtful comments made on our book, Responsible Brains, by a stellar group of scholars. Our reply focuses on two topics discussed in the commenting papers: first, the issue of responsibility for negligent behavior; and second, the broad claim that facts about brain function are normatively inert. In response to worries that our theory lacks normative implications, we will concentrate on an area where our theory has clear relevance to law and legal (...) policy: juvenile responsibility.

Examining stem cell biology from a philosophy of science perspective, this book clarifies the field's central concept, the stem cell, as well as its aims, methods, models, explanations and evidential challenges. The first chapters discuss what stem cells are, how experiments identify them, and why these two issues cannot be completely separated. The basic concepts, methods and structure of the field are set out, as well as key limitations and challenges. The second part of the book shows how rigorous explanations (...) emerge from stem cell experiments, and compares these to other kinds of scientific explanation. Model organisms, the role of genes, and the significance of collaboration are also discussed. The last part of the book considers relations to systems biology and clinical medicine, arguing that both the mathematical models of the former, and ethical principles of the latter, are necessary for stem cell biology to deliver on its promises.

What things count as individuals, and how do we individuate them? It is a classic philosophical question often tackled from the perspective of analytic metaphysics. This volume proposes that there is another channel by which to approach individuation -- from that of scientific practices. From this perspective, the question then becomes: How do scientists individuate things and, therefore, count them as individuals? This volume collects the work of philosophers of science to engage with this central philosophical conundrum from a new (...) angle, highlighting the crucial topic of experimental individuation and building upon recent, pioneering work in the philosophy of science. An introductory chapter foregrounds the problem of individuation, arguing it should be considered prior to the topic of individuality. The following chapters address individuation and individuality from a variety of perspectives, with prominent themes being the importance of experimentation, individuation as a process, and pluralism in individuation's criteria. Contributions examine individuation in a wide range of sciences, including stem cell biology, particle physics, and community ecology. Other chapters examine the metaphysics of individuation, its bearing on realism/antirealism debates, and interrogate epistemic aspects of individuation in scientific practice. In exploring individuation from the philosophy of biology, physics, and other scientific subjects, this volume ultimately argues for the possibility of several criteria of individuation, upending the tenets of traditional metaphysics. It provides insights for philosophers of science, but also for scientists interested in the conceptual foundations of their work. (shrink)

Stem cell biology and systems biology are two prominent new approaches to studying cell development. In stem cell biology, the predominant method is experimental manipulation of concrete cells and tissues. Systems biology, in contrast, emphasizes mathematical modeling of cellular systems. For scientists and philosophers interested in development, an important question arises: how should the two approaches relate? This essay proposes an answer, using the model of Waddington’s landscape to triangulate between stem cell and systems approaches. This simple abstract model represents (...) development as an undulating surface of hills and valleys. Originally constructed by C. H. Waddington to visually explicate an integrated theory of genetics, development and evolution, the landscape model can play an updated unificatory role. I examine this model’s structure, representational assumptions, and uses in all three contexts, and argue that explanations of cell development require both mathematical models and concrete experiments. On this view, the two approaches are interdependent, with mathematical models playing a crucial but circumscribed role in explanations of cell development. (shrink)

What is a stem cell? The answer is seemingly obvious: a cell that is also a stem, or point of origin, for something else. Upon closer examination, however, this combination of ideas leads directly to fundamental questions about biological development. A cell is a basic category of living thing; a fundamental 'unit of life.' A stem is a site of growth; an active source that supports or gives rise to something else. Both concepts are deeply rooted in biological thought, with (...) rich and complex histories. The idea of a stem cell unites them, but the union is neither simple nor straightforward. This book traces the origins of the stem cell concept, its use in stem cell research today, and implications of the idea for stem cell experiments, their concrete results, and hoped-for clinical advances.

An oracle was reported to have said, "No one is wiser than Socrates." And in fact it was Socrates’ life’s work to interpret these words, which demanded and defined the practice of philosophy. Each of these original essays attends carefully to the specifics of the _Apology_, looking to its dramatic details, its philosophic teaching, and its complexity as a work of writing to bring into focus the "Socrates" of the _Apology_. Overall, the contributors, distinguished scholars of ancient philosophy, share a (...) belief in the unity of the letter and the spirit of Platonic philosophy: the conviction that the Platonic text cannot be reached except through reading and cannot be read except through thinking. In this way, the readings in this volume mirror Socrates’ own hermeneutical practice of uniting the demands of the mind and the demands of the text—the Socratic "examination." The result, true to the Socratic injunction that the unexamined life is not worth living, continues that practice of examination, here offering a reexamination of Socrates in the _Apology_. (shrink)

If there is collective scientific knowledge, then at least some scientific groups have beliefs over and above the personal beliefs of their members. Gilbert's plural-subjects theory makes precise the notion of ‘over and above’ here. Some philosophers have used plural-subjects theory to argue that philosophical, historical and sociological studies of science should take account of collective beliefs of scientific groups. Their claims rest on the premise that our best explanations of scientific change include these collective beliefs. I argue that Gilbert's (...) account of collective scientific belief does not provide a better explanation of scientific change than a non-collective alternative. A different defence of collective scientific belief and knowledge is needed. (shrink)

This paper examines a case of failed interdisciplinary collaboration, between experimental stem cell research and theoretical systems biology. Recently, two groups of theoretical biologists have proposed dynamical systems models as a basis for understanding stem cells and their distinctive capacities. Experimental stem cell biologists, whose work focuses on manipulation of concrete cells, tissues and organisms, have largely ignored these proposals. I argue that ‘failure to communicate’ in this case is rooted in divergent views of explanation: the theoretically-inclined modelers are committed (...) to a version of the covering-law view, while experimental stem cell biologists aim at mechanistic explanations. I propose a way to reconcile these two explanatory approaches to cell development, and discuss the significance of this result for interdisciplinary collaboration in systems biology and beyond.

Ontologies of living things are increasingly grounded on the concepts and practices of current life science. Biological development is a process, undergone by living things, which begins with a single cell and (in an important class of cases) ends with formation of a multicellular organism. The process of development is thus prima facie central for ideas about biological individuality and organismality. However, recent accounts of these concepts do not engage developmental biology. This paper aims to fill the gap, proposing the (...) lineage view of stem cells as an ontological framework for conceptualizing organismal development. This account is grounded on experimental practices of stem cell research, with emphasis on new techniques for generating biological organization in vitro. On the lineage view, a stem cell is the starting point of a cell lineage with a specific organismal source, time-interval of existence, and ‘tree topology’ of branch-points linking the stem to developmental termini. The concept of ‘enkapsis’ accommodates the cell-organism relation within the lineage view; this hierarchical notion is further explicated by considering the methods and results of stem cell experiments. Results of this examination include a (partial) characterization of stem cells’ developmental versatility, and the context-dependence of developmental processes involving stem cells. (shrink)

This essay examines the role of social interactions in the search for blood stem cells, in a recent episode of biomedical research. Linked to mid-20th century cell biology, genetics and radiation research, the search for blood stem cells coalesced in the 1960s and took a developmental turn in the late 1980s, with significant ramifications for immunology, stem cell and cancer biology. Like much contemporary biomedical research, this line of inquiry exhibits a complex social structure and includes several prominent scientific successes, (...) recognized as such by participating researchers. I use personal interviews and the published record to trace the social interactions crucial for scientific success in this episode. All recognized successes in this episode have two aspects: improved models of blood cell development, and new interfaces with other lines of research. The narrative of the search for blood stem cells thus yields a robust account of scientific success in practice, which generalizes to other scientific episodes and lends itself to expansion to include wider social contexts.

Epistemology of science is currently polarized. Descriptive accounts of the social aspects of science coexist uneasily with normative accounts of scientific knowledge. This tension leads students of science to privilege one of these important aspects over the other. I use an episode of recent immunology research to develop an integrative account of scientific inquiry that resolves the tension between sociality and epistemic success. The search for the hematopoietic stem cell by members of Irving Weissman’s laboratory at Stanford University Medical Center (...) exhibits both the goal-oriented character of contemporary immunology and the importance of social interactions in successful achievement of those goals. This episode includes three kinds of epistemic success: characterization of HSC, formation of new interdisciplinary interfaces, and reconciliation of apparently incompatible models. All three depend on coordinating the work of diverse participants via social interactions. Together, they reveal the crucial role of social interactions within and between research groups in producing epistemic success. These features of the search for the HSC generalize to immunology as a whole, and plausibly to other disciplines. This account thus resolves the polarizing tension in epistemology of science, and complements individualistic accounts of scientific knowledge and rationality. (shrink)

Ludwik Fleck’s theory of thought-styles has been hailed as a pioneer of constructivist science studies and sociology of scientific knowledge. But this consensus ignores an important feature of Fleck’s epistemology. At the core of his account is the ideal of ‘objective truth, clarity, and accuracy’. I begin with Fleck’s account of modern natural science, locating the ideal of scientific objectivity within his general social epistemology. I then draw on Fleck’s view of scientific objectivity to improve upon reflexive accounts of the (...) origin and development of the theory of thought-styles, and reply to objections that Fleck’s epistemological stance is self-undermining or inconsistent. Explicating the role of scientific objectivity in Fleck’s epistemology reveals his view to be an internally consistent alternative to recent social accounts of scientific objectivity by Harding, Daston and Galison. I use these contrasts to indicate the strengths and weaknesses of Fleck’s innovative social epistemology, and propose modifications to address the latter. The result is a renewed version of Fleck’s social epistemology, which reconciles commitment to scientific objectivity with integrated sociology, history and philosophy of science. (shrink)

Stem cells are defined as having capacities for both self-renewal and differentiation. Many different entities satisfy this working definition. I show that this general stem cell concept is relative to a cell lineage, temporal duration, and characters of interest. Experiments specify values for these variables. So claims about stem cells must be understood in terms of experimental methods used to identify them. Furthermore, the stem cell concept imposes evidential constraints on interpretation of experimental results. From these constraints, it follows that (...) claims about stem cell capacities are inherently uncertain. This result has important implications for stem cell research. (shrink)

Aristotle is one of the greatest philosophers who have written on the nature of man. And when he chose to write on man and his pursuit of happiness, he did it by describing carefully the virtues which together constitute the good life. He tells us that moral virtue in general is a habit of choice, essentially consisting in the preservation of the mean, relatively to the persons concerned, as determined by rule, i.e., by the rule by which the prudent man (...) would determine it. In the pursuit of true happiness, then, we must be guided by the prudent man. Hence the importance of prudence in the moral life. For Aristotle, as for St. Thomas, prudence is the auriga virtutum. It deserves careful study, and indeed, it has been studied profoundly by both Philosopher and Theologian. They are in agreement for the most part, but on one point at least they differ greatly. For a better understanding of a virtue Aristotle very often describes the corresponding vice. The contrast of virtue and vice is looked upon as an Aristotelian technique. But there is one vice to which Aristotle devotes no attention: the vice of imprudence. St. Thomas, on the other hand, has no hesitation in treating specifically of the vice of imprudence, its special place and its various parts. (shrink)

The philosophical faculty of the Jesuit Berchmanskolleg in Pullach has long since made its mark in the publishing world, and the new series of philosophical studies from Father Lotz and his associates, of which these two volumes are an auspicious beginning, shows every sign of living up to the high standard we have come to expect. Volume I is a collection of five essays: a comparison between the Thomistic and Kantian theory of knowledge, by Fr. de Vries; the transcendental method (...) in Kant and in Scholasticism, by Fr. Lotz; the Absolute in the Kritik der reinen Vernunft, by Fr. Brugger; formalism in Kant’s ethics, by Dr. Schmucker; and the relationship between Kant and Heidegger, by Fr. Coreth. It concludes with a particularly useful bibliography of scholastic literature on Kant between 1920 and 1955, compiled by Fr. Brugger. After Jansen, Maréchal is the scholastic writer with most published studies on Kant to his credit, and it is not surprising that his influence should make itself felt in the present volume. His monumental Le point de départ de la métaphysique marked a definite turning–point in the scholastic attitude towards Kant, and one has only to read this collection of studies to realise how the atmosphere has changed in the course of the last fifty years. Fr. de Vries devotes almost two–thirds of his essay to what St. Thomas and Kant hold in common with regard to the discursive nature of human understanding, the structure of the sense–image and its relation to the intellectual concept, though he also brings out the fundamental difference between the two on the questions of self–consciousness, natural theology and the reality of the external world. Not only does he show a healthy respect for the many grains of truth in the philosophy of Kant, but he insists that Thomists have much to learn from the German philosopher on the question of strict, critical method. Scholastics of the traditional school were satisfied with what Fr. Lotz describes as the “objective method” and rejected the “subjective” as smacking of subjectivism or idealism. In the longest essay of the five, Fr. Lotz compares the Kantian and Scholastic methods. Kant himself described his Kritik der reinen Vernunft as a “treatise on method rather than a scientific system”, and in the course of the book he condemns the objective approach as dogmatic and uncritical, leaving only the subjective method, which rules out any possibility of metaphysics. Fr. Lotz rightly asserts that even the most modern scholastic cannot dispense with the objective method, but he maintains that it demands to be completed by the subjective. Many scholastics will agree with him on the usefulness of the latter, and indeed an amount of research has been done in this field in recent decades. But how many will agree when he says that scholastic objectivism includes the subjective or transcendental method as the only way, or the only basis on which objectivism can stand? Maréchal’s influence is evident in his treatment of the faculties of the soul. But, however one may quibble at individual points in the book, it nevertheless remains a very valuable contribution to the scholastic literature on Kant. (shrink)
