It is a little understood fact that the system of formal logic presented in Wittgenstein’s Tractatusprovides the basis for an alternative general semantics for a predicate calculus that is consistent and coherent, essentially independent of the metaphysics of logical atomism, and philosophically illuminating in its own right. The purpose of this paper is threefold: to describe the general characteristics of a Tractarian-style semantics, to defend the Tractatus system against the charge of expressive incompleteness as levelled by Robert Fogelin, and to (...) give a semantics for a formal language that is the Tractarian equivalent of a first-order predicate calculus. Of note in regard to the latter is the fact that a Tractatusstyle truth-definition makes no appeal to the technical trick of defining truth in terms of the satisfaction of predicates by infinite sequences of objects, yet is materially equivalent to the usual Tarski-style truth-definitions.

Asperó and Schindler have completely solved the Axiom [Formula: see text] vs. [Formula: see text] problem. They have proved that if [Formula: see text] holds then Axiom [Formula: see text] holds, with no additional assumptions. The key question now concerns the relationship between [Formula: see text] and Axiom [Formula: see text]. This is because the foundational issues raised by the problem of Axiom [Formula: see text] vs. [Formula: see text] arguably persist in the problem of Axiom [Formula: see text] vs. (...) [Formula: see text]. The first of our two main theorems is that Axiom [Formula: see text] is equivalent to Axiom [Formula: see text], and as a corollary we show that Axiom [Formula: see text] fails in all the known models of [Formula: see text]. This suggests that [Formula: see text] actually refutes Axiom [Formula: see text]. Our second main theorem is that the [Formula: see text] Conjecture holds assuming [Formula: see text]. This is the strongest partial result known on this conjecture which is one of the central open problems of [Formula: see text]-theory and [Formula: see text]-logic. These results identify a fundamental asymmetry between the Continuum Hypothesis and any axiom which is both [Formula: see text]-expressible and which implies [Formula: see text], on the basis of generic absoluteness for the simplest of the nontrivial sentences of Third-Order Number Theory. These are the [Formula: see text]-sentences with no parameters. Such sentences are those which simply assert the existence of a set [Formula: see text] for which some property involving only quantification over [Formula: see text] holds. (shrink)

In these essays, Hugh J. McCann develops a unified perspective on human action. Written over a period of twenty-five years, the essays provide a comprehensive survey of the major topics in contemporary action theory. In four sections, the book addresses the ontology of action ; the foundations of action ; intention, will, and freedom; and practical rationality. McCann works out a compromise between competing perspectives on the individuation of action ; explores the foundations of action and defends a volitional (...) theory; argues for a libertarian view of both the formation and the execution of intention; and considers the question of consistency in rational intentions, as well as the relationship between practical and theoretical reasoning. -/- Among the original features of McCann's work are his defense of both fine- and coarse-grained actions and his arguments for a noncausal theory of the relation between intention and action. He also suggests that intentions need not be consistent, either with each other or with beliefs about success. And he contends that intention formation is an intrinsically ratiocinative procedure, distinct from reasoning about what action would be best. (shrink)

Niche construction is a concept that captures a wide array of biological phenomena, from the environmental effects of metabolism to the creation of complex structures such as termite mounds and beaver dams. A central point in niche construction theory is that organisms do not just passively undergo developmental, ecological, or evolutionary processes, but are also active participants in them Evolution: From molecules to men, Cambridge University Press, Cambridge, 1983; Laland KN, Odling-Smee J, Feldman MW, In: KN Laland and T Uller (...) Evolutionary causation: Biological and philosophical reflections, MIT Press, Cambridge, MA, 2019). In this paper, we distinguish between two fundamentally different ways in which organisms are active participants: as agents and as contributors. Roughly, organisms act as agents when niche constructing effects are a result of a goal-directed behavior over which the organisms have some degree of control. Organisms act as contributors when the niche constructing effects do not arise from a goal to perform the constructive activity. As illustrative examples we discuss plants altering leaf-morphology to optimize light exposure as reported by Sultan and bacteria creating novel niches through excreting energy-rich metabolites. The difference between agential and contributional niche construction is important for understanding the different ways organisms can actively participate in development, ecology, and evolution. Additionally, this distinction can increase our understanding of how the capacity of agency is distributed across the tree of life and how agency influences developmental and evolutionary processes.

This book takes a look at American educational history and focuses on the collaboration between teachers, policymakers, philosophers, and activists.

Our actions, individually and collectively, inevitably affect others, ourselves, and our institutions. They shape the people we become and the kind of world we inhabit. Sometimes those consequences are positive, a giant leap for moral humankind. Other times they are morally regressive. This propensity of current actions to shape the future is morally important. But slippery slope arguments are a poor way to capture it. That is not to say we can never develop cogent slippery slope arguments. Nonetheless, given their (...) most common usage, it would be prudent to avoid them in moral and political debate. They are often fallacious and have often been used for ill. They are normally used to defend the moral status quo. Even when they are cogent, we can always find an alternate way to capture their insights. Finally, by accepting that the moral roads on which we travel are slippery, we become better able to successfully navigate them. (shrink)

In this paper, we outline a framework for understanding the different kinds of knowledge required for medical practice and use this framework to show how scientism undermines aspects of this knowledge. The framework is based on Michael Polanyi’s claim that knowledge is primarily the product of the contemplations and convictions of persons and yet at the same time carries a sense of universality because it grasps at reality. Building on Polanyi’s ideas, we propose that knowledge can be described along two (...) intersecting “dimensions”: the tacit–explicit and the particular–general. These dimensions supersede the familiar “objective−subjective” dichotomy, as they more accurately describe the relationship between medical science and medical practice. Scientism, we argue, excludes tacit and particular knowledge and thereby distorts “clinical reality” and impairs medical practice and medical ethics. (shrink)

Biologists explain organisms’ behavior not only as having been programmed by genes and shaped by natural selection, but also as the result of an organism’s agency: the capacity to react to environmental changes in goal-driven ways. The use of such ‘agential explanations’ reopens old questions about how justified it is to ascribe agency to entities like bacteria or plants that obviously lack rationality and even a nervous system. Is organismic agency genuinely ‘real’ or is it just a useful fiction? In (...) this paper we focus on two questions: whether agential explanations are to be interpreted ontically, and whether they can be reduced to non-agential explanations (thereby dispensing with agency). The Kantian approach we identify interprets agential explanations non-ontically, yet holds agency to be indispensable. Attributing agency to organisms is not to be taken literally in the way we attribute physical properties such as mass or acceleration, but nor is it a mere heuristic or predictive tool. Rather, it is an inevitable consequence of our own rational capacity: as long as we are rational agents ourselves, we cannot avoid seeing agency in organisms. (shrink)

I hold no view as to what actions are basic, but I shall attempt to show in what follows that actions like raising an arm never are. My contention is that these actions involve actions of physical exertion on the part of the agent, the involvement being of a sort generally taken to be excluded by an actions being basic.

Path-dependence offers a promising way of understanding the role historicity plays in explanation, namely, how the past states of a process can matter in the explanation of a given outcome. The two main existing accounts of path-dependence have sought to present it either in terms of dynamic landscapes or branching trees. However, the notions of landscape and tree both have serious limitations and have been criticized. The framework of causal networks is both more fundamental and more general that that of (...) landscapes and trees. Within this framework, I propose that historicity in networks should be understood as symmetry breaking. History matters when an asymmetric bias towards an outcome emerges in a causal network. This permits a quantitative measure for how path-dependence can occur in degrees, and offers suggestive insights into how historicity is intertwined both with causal structure and complexity.

Hans Georg Gadamer is responsible for the re-emergence of hermeneutics in modern philosophy. This fourth volume of the Continental Philosophy series opens with an account by Gadamer of his own life and work and their relation to the achievements of hermeneutics. Gadamer and Hermeneutics then presents a series of essays that link Gadamer to other major contemporary philosophers. There are special sections on Gadamer's relationship to Heidegger, Ricoeur, Barthes, Derrida and Habermas. The volume concludes with three essays around the questions (...) of metaphor, science and the text, each essay shedding a special light on the hermeneutic process. (shrink)

Philosophers of science and metascientists alike typically model scientists’ behavior as driven by credit maximization. In this article I argue that this modeling assumption cannot account for how scientists have a default level of trust in each other’s assertions. The normative implication of this is that science policy should not focus solely on incentive reform.

Most philosophers have given up George Berkeley’s proof for the existence of God as a lost cause, for in it, Berkeley seems to conclude more than he actually shows. I defend the proof by showing that its conclusion is not the thesis that an infinite and perfect God exists, but rather the much weaker thesis that a very powerful God exists and that this God’s agency is pervasive in nature. This interpretation, I argue, is consistent with the texts. It is (...) also an important component of Berkeley’s philosophical project, which consists of launching many small arguments against his philosophical and theological opponents. (shrink)

A model of interreligious theology that seeks to reconcile the ideal of religious tolerance with an acknowledgement of the extent to which religious communities construct identity on the basis of religious differences.

This article examines the emergence of the Nyāya distinction between vāda and jalpa as didactic-scientific and agonistic-sophistical forms of debate, respectively. Looking at the relevant sutras in Gautama’s Nyāya-sūtra (NS 1.2.1-3) in light of the earlier discussion of the types of debate in Caraka Saṃhitā 8, the article argues that certain ambiguities and obscurities in the former text can be explained on the hypothesis that the early Nyāya presupposed an agonistic understanding of vāda similar to what we find in Caraka.

Contemporary argumentation theory has developed an impressive array of norms, goals and virtues applicable to ideal argument. But what is the moral status of these prescriptions? Is an interlocutor who fails to live up to these norms guilty of a moral failing as well as an epistemic or cognitive error? If so, why? In answering these questions, I argue that deliberation’s epistemic and cognitive goods attach to important ethical goods, and that respect for others’ rationality, the ethics of joint action, (...) and the importance of consensus join forces with these goods to provide strong reasons for cleaving to high standards of argument. I sketch an illustrative continuum of argument practices of different deliberative-cum-ethical standards, and consider how one should ethically respond when faced with an interlocutor employing less than ideal standards.

What level of government subsidy of higher education is justified, in what form, and for what reasons? We answer these questions by applying the hypothetical insurance approach, originally developed by Ronald Dworkin in his work on distributive justice. On this approach, when asking how to fund and deliver public services in a particular domain, we should seek to model what would be the outcome of a hypothetical insurance market: we stipulate that participants lack knowledge about their specific resources and risks, (...) and ask what insurance contracts they would take out to secure different types of benefit and protection in the domain in question. The great benefit of the hypothetical insurance approach is that it allows us to take apparently intractable questions about interpersonal distribution and transform them into questions about intrapersonal distributions: that is, questions about how an individual would choose to distribute risks and resources across the various lives that they might end up living, in light of their individual ambitions and preferences. Applying this approach to higher education, we argue that the UK model of higher education funding in which the costs of an individual's higher education are shared between general taxation and the individual herself, with the latter element to be paid retrospectively through an income-contingent state-backed loan, is vindicated as just. In particular, we argue that it is more just than alternatives such as a graduate tax, full funding through general taxation, and full privatisation. (shrink)

“Meta-argument allegations” consist of protestations that an interlocutor’s speech is wrongfully offensive or will trigger undesirable social consequences. Such protestations are meta-argument in the sense that they do not interrogate the soundness of an opponent’s argumentation, but instead focus on external features of that argument. They are allegations because they imply moral wrongdoing. There is a legitimate place for meta-argument allegations, and the moral and epistemic goods that can come from them will be front of mind for those levelling such (...) allegations. But I argue there is a dark side to such allegations, and their epistemic and moral costs must be seriously weighed. Meta-argument allegations have a concerning capacity to derail discussions about important topics, stymieing argumentational interactions and the goods they provide. Such allegations can license efforts to silence, punish and deter—even as they provoke the original speaker to retaliate in kind. Used liberally, such allegations can escalate conflicts, block open-mindedness, and discourage constructive dialogues. In response, I defend “argumentational tolerance”—a principled wariness in employing meta-argument allegations—as a virtue of ethical argument. (shrink)

The challenge this book addresses is to demonstrate how, in teaching content knowledge, the development of intellectual and moral dispositions as virtues is not merely a good idea, or peripheral to that content, but deeply embedded in the logic of searching for knowledge and truth. It offers a powerful example of how philosophy of education can be brought to bear on real problems of educational research and practice – pointing the reader to re-envision what it means to educate children by (...) developing the person, instead of simply knowledge and skills. Connected intimately to the practice of teaching and teacher education, the book sets forth an alternative theory of education where the developing person is at the center of education set in a moral space and a political order. To this end, a framework of public and personal knowledge forms the content, to which personal dispositions are integral, not peripheral. The book’s pedagogy is invitational, welcoming its readers as companions in inquiry and thought about the moral aspects of what we teach as knowledge. (shrink)

ABSTRACT Biomedical experimentation on animals is justified, researchers say, because of its enormous benefits to human beings. Sure, animals suffer and die, but that is morally insignificant since the benefits of research incalculably outweigh the evils. Although this utilitarian claim appears straightforward and relatively uncontroversial, it is neither straightforward nor uncontroversial. This defence of animal experimentation is likely to succeed only by rejecting three widely held moral presumptions. We identify these assumptions and explain their relevance to the justification of animal (...) experimentation. We argue that, even if non‐human animals have considerably less moral worth than humans, experimentation is justified only if the benefits are overwhelming. By building on and expanding on arguments offered in earlier papers, we show that researchers cannot substantiate their claims on behalf of animal research. We conclude that there is currently no acceptable utilitarian defence of animal experimentation. Moreover, it is unlikely that there could be one. Since most apologists of animal experimentation rely on utilitarian justifications of their practice, it appears that biomedical experimentation on animals is not morally justified. (shrink)

Integrity looks dangerous. Passionate willpower, focused devotion and driving self-belief nestle all-too-closely to extremism, narcissism and intolerant hubris. How can integrity skirt such perils? This question opens the perennial issue of whether devout, driven devotees can guard themselves from antisocial extremes. Current proposals to inoculate integrity from moral danger hone in on integrity’s reflective side. I argue that this epistemic approach disarms integrity’s dangers only by stripping it of everything that initially made it worthwhile. Instead, I argue that integrity contains (...) substantive moral principles serving to surgically target the dangers the trait would otherwise pose. The person of integrity avoids extremism not by questioning whether her values are right, but by recognizing that in a social world whether her values are right is not the only factor that bears on how she should act. Normatively, the proposed account allows integrity to retain its intuitive allures of willpower, direction and unified character. Descriptively, it explains the surprising capacity for principled compromise displayed by canonical figures of integrity. Ultimately, integrity empowers us to be fit for society, even as we are true to ourselves. (shrink)
