This article investigates the semantics of sentences that express numerical averages, focusing initially on cases such as 'The average American has 2.3 children'. Such sentences have been used both by linguists and philosophers to argue for a disjuncture between semantics and ontology. For example, Noam Chomsky and Norbert Hornstein have used them to provide evidence against the hypothesis that natural language semantics includes a reference relation holding between words and objects in the world, whereas metaphysicians such as Joseph Melia and (...) Stephen Yablo have used them to provide evidence that apparent singular reference need not be taken as ontologically committing. We develop a fully general and independently justified compositional semantics in which such constructions are assigned truth conditions that are not ontologically problematic, and show that our analysis is superior to all extant rivals. Our analysis provides evidence that a good semantics yields a sensible ontology. It also reveals that natural language contains genuine singular terms that refer to numbers. (shrink)

Psychiatric and neurological disorders have historically provided key insights into the structure-function rela- tionships that subserve human social cognition and behavior, informing the concept of the ‘social brain’. In this review, we take stock of the current status of this concept, retaining a focus on disorders that impact social behavior. We discuss how the social brain, social cognition, and social behavior are interdependent, and emphasize the important role of development and com- pensation. We suggest that the social brain, and its (...) dysfunction and recovery, must be understood not in terms of specific structures, but rather in terms of their interaction in large-scale networks.

We lead off this issue of Childhood and Philosophy with a collection of testimonies, homages, and brief memoirs offered from around the world in response to the death of the founder of Philosophy for Children, Matthew Lipman on December 26, 2010, at the age of 87. To characterize Lipman as “founder” is completely accurate, but barely evokes the role he played in conceiving, giving birth to, and nurturing this curriculum cum pedagogy that became a movement, and which has taken root (...) in over 40 countries, from Iceland to Nigeria to Taiwan to Chile and everywhere in between. The movement itself is broader than the program, which has in fact experienced multiple transformations in multiple contexts over its half-century of life. In fact, as many of the testimonies below either state outright or imply, the movement is an emancipatory one and thus implicitly political, infused with all the long-suffering hope for our species inspired in us by the fact of natality, and by our own intuitive faith in the transformative power of reason—or as Lipman came to call it, “reasonableness.” For those seized by its educational possibilities, it presents a sudden influx of sunlight and fresh air into an institution long stultified by its own rigid habitus, and promises the reconstruction of schooling in the image of authentic democratic practice that recognizes and honors the unique capacities of children. As Philosophy in the Classroom—Lipman’s first and now classic statement of educational philosophy--puts it, the movement promises a re-orientation of the goal of education from information (or “learning”) to meaning, and inaugurates the dialogue with childhood and children that follows from that. Lipman was not just founder of this movement but creator, inventor, developer, convener, organizer, faithful soldier, ambassador, apologist, polemicist, propagandist, and, finally, undying optimist.

At the very least, even though Chinese schools do not look very different from those in the West, China offers an opportunity for Philosophy for Children to question its basis, its methodology, its aims. It seems to be expressing a different cultural voice, and to be disposed to the kind of dialogue we are more used to claiming than practicing. Both Kunming and Shanghai provide, in their own ways, formidable contexts: the deep, strong and disciplined educators of Railway Station School (...) of Kunming and the scholarly, sophisticated and committed members of the Shanghai institute for Research in the Human Sciences seem determined to take Philosophy for Children, not just beyond their own limits as Chinese, but beyond the limits Philosophy for Children has already established for itself in the West. Philosophy for Children in China, then, looks like a wonderful opportunity to think ourselves--what we are as educators engaged in the practice of philosophy--again. An invitation to think ourselves again. Is this not what dialogue and philosophy are about? It’s up to us to accept the invitation. (shrink)

Suicide is a complex act whose meanings, while sometimes tragic, vary widely. This chapter surveys the ethical landscape surrounding algorithmic methods of suicide prevention especially as it pertains to social media activity and to the moderation of online suicide communities. We begin with a typology of suicide, distinguishing between varied goals in which suicide may factor as a means. Suicides should be understood as an act with varied eliciting desires, meanings, consequences, and ethics. Further,while many suicides may be grounded on (...) irrational desire, we argue that a desire to suicide may nonetheless be rational in some cases. We then offer a survey of the attempts by social media corporations to create suicide prediction algorithms and launch interventions aimed at preventing suicide as well as an overview of the current ethical debate. We argue that the values embedded within algorithmic suicide prevention nudges are “thick” in a substantive sense and deserving of scrutiny. Given that debates about the rationality, meaning, and permissibility of suicide are common and subject to intracultural and cross-cultural differences, we maintain that the task of suicide prediction is ill-suited to algorithmic approaches. Despite an algorithm’s ability to quantify a complex phenomenon like suicide risk and its appearance of objectivity, any suicide prediction algorithm is thoroughly subjective and involves moral judgments all the way down. Any such algorithm would necessarily impose a normative stance on suicide onto its user base that is subject to reasonable intra and cross-cultural disagreement. (shrink)

While artificial womb technology is currently being studied for the purpose of improving neonatal care, I contend that this technology ought to be pursued as a means to address the unprecedented rate of unintended pregnancies. But ectogenesis, alongside other emerging reproductive technologies, is problematic insofar as it threatens to disrupt the natural link between procreation and parenthood that is normally thought to generate rights and responsibilities for biological parents. I argue that there remains only one potentially viable account of parenthood: (...) the voluntarist account, which construes parental rights as robust moral obligations that must be voluntarily undertaken. The problem is that this account mistakenly presumes a patriarchal divide between procreation and parenthood. I propose a reframing of procreation and parenthood from a feminist perspective that recognises gestational motherhood as involving robust moral obligations that ought to be voluntarily undertaken. If this were the case, all gestational mothers would be, by definition, willing mothers. To make this happen I argue that ectogenesis technology must be a widely available reproductive option.

Indiscipline in schools has attracted the attention of many people and has eventually become the focus of discussions on many platforms. The purpose of the study was to find out the perceptions of teachers and students at the Abuakwa South Municipality of Ghana on student indiscipline behaviours. The study employed the descriptive survey and the approach was concurrent mixed method, involving bothquantitative and qualitative paradigms. Purposive and simple random sampling methods were used to obtaina sample size of five hundred and (...) thirty (530) respondents. The main instruments used for the study were questionnaire and a semi-structured interview guide. Data was analysed using inferential statistics and content analysis. Findings from the study revealed that; there was no perceptual difference between students and teachers views on acts that constitute disciplinary behaviours. Additional, there were differences in thestudents and teachers perceptions of the influences of peer pressure on students’ disciplinary behaviours. Itwas recommended among others that peer counselling sessions should be organized periodically among students for them to be aware of acceptable behaviours in the school system and how they can maintain desirable behaviours.

Social scientists, political scientists and philosophers debate key concepts such as democracy, power and autonomy. Contested concepts like these pose questions: Are terms such as “democracy” hopelessly ambiguous? How can two theorists defend alternative accounts of democracy without talking past each other? How can we understand debates in which theorists disagree about what democracy is? This paper first discusses the popular strategy to answer these questions by appealing to Rawls’s distinction between concepts and conceptions. According to this approach, defenders of (...) rival conceptions of, e.g. justice can disagree without talking past each other because they share the concept of justice. It is argued that this idea is attractive but limited in application and that it fails to do justice to the dynamic and normative aspects of concept formation. Reflective equilibrium is then suggested as an alternative approach. It replaces the static contrast between a conceptual ‘core’ and competing conceptions by a dynamic perspective of concept formation as a partly normative undertaking: pre-theoretic language use and commitments can provide a shared starting point for developing alternative accounts which yield different concepts of, e.g. justice. This perspective provides a new understanding of how it is possible that different theorists defend rival accounts of, e.g. justice, without talking past each other. (shrink)

This paper works out the scheme of “institutional competences” that underlies the famous Hart and Sacks Legal Process Materials first distributed in final mimeographed form in1958. The Materials were not published during the life times of their authors but were nonetheless a major influence on American legal thought from their first distribution as course materials at Harvard Law School until their abrupt fall from prominence in the early 1970s. The Materials offer the scheme as a solution to the apparent anomaly (...) in a democracy of the law making power in both public and private law of unelected judges serving long terms. The paper critiques the Hart and Sacks solution, called law making through “reasoned elaboration,” which they claimed was sharply distinct from legislative law making or administrative fiat. The paper argues that in both public and private law the materials the judge is to elaborate are characterized by contradictory internal logics. The judge has to choose between them without a meta-criterion. In cases with high stakes, extra-juristic normative orientations, whether moral theories or political ideologies, will come into play, regardless of the judge’s commitment to excluding them. The second part of the paper places Hart and Sacks in a larger historical and comparative context of efforts to solve the problem of social order by way of legal rationality. These two parts were preceded in the original paper by a long discussion, now lost but never very satisfying to me, of the Hart and Sacks theory of “private ordering” in relation to state regulatory power. I wrote the paper for extra credit in the spring of 1970 as a third year student at the Yale Law School. I’ve corrected a few typos but haven’t changed it in any other way. I never published it but it was circulated to a limited extent among Legal Process devotees. Eskridge and Frickey, editors of the Materials as published finally in 1994, credit it, along with another unpublished student paper by Roberto Unger, with hastening the demise of the Materials as a master text. The first part of this version of the paper was recently published in Droit et Philosophie, no. 13, p. 97-117 (2021). (shrink)

This study provides a unified theory of properties, relations, and propositions (PRPs). Two conceptions of PRPs have emerged in the history of philosophy. The author explores both of these traditional conceptions and shows how they can be captured by a single theory.

This paper constructs a model of metaphysical indeterminacy that can accommodate a kind of ‘deep’ worldly indeterminacy that arguably arises in quantum mechanics via the Kochen-Specker theorem, and that is incompatible with prominent theories of metaphysical indeterminacy such as that in Barnes and Williams (2011). We construct a variant of Barnes and Williams's theory that avoids this problem. Our version builds on situation semantics and uses incomplete, local situations rather than possible worlds to build a model. We evaluate the resulting (...) theory and contrast it with similar alternatives, concluding that our model successfully captures deep indeterminacy. (shrink)

Scientific information plays an important role in shaping policies and recommendations for behaviors that are meant to improve the overall health and well-being of the public. However, a subset of the population does not trust information from scientific authorities, and even for those that do trust it, information alone is often not enough to motivate action. Feelings of shame can be motivational, and thus some recent public policies have attempted to leverage shame to motivate the public to act in accordance (...) with science-based recommendations. We argue that because these shame policies are employed in non-communal contexts, they are both practically ineffective and morally problematic: shame is unlikely to be effective at motivating the public to behave in accordance with science-based policy, and shaming citizens is an unethical way to get them to comply. We argue that shame-based policies are likely to contribute to further distrust in scientific authority. (shrink)

The phenomenology of a priori intuition is explored at length (where a priori intuition is taken to be not a form of belief but rather a form of seeming, specifically intellectual as opposed to sensory seeming). Various reductive accounts of intuition are criticized, and Humean empiricism (which, unlike radical empiricism, does admit analyticity intuitions as evidence) is shown to be epistemically self-defeating. This paper also recapitulates the defense of the thesis of the Autonomy and Authority of Philosophy given in the (...) author’s “A Priori Knowledge and the Scope of Philosophy” (Philosophical Studies, 1996).

The paper begins with a clarification of the notions of intuition (and, in particular, modal intuition), modal error, conceivability, metaphysical possibility, and epistemic possibility. It is argued that two-dimensionalism is the wrong framework for modal epistemology and that a certain nonreductionist approach to the theory of concepts and propositions is required instead. Finally, there is an examination of moderate rationalism’s impact on modal arguments in the philosophy of mind -- for example, Yablo’s disembodiment argument and Chalmers’s zombie argument. A less (...) vulnerable style of modal argument is defended, which nevertheless wins the same anti-materialist conclusions sought by these other arguments. (shrink)

Este artículo examina la rica textura de los themata de Holton. Holton argumenta que dentro de las normas racionales establecidas hay espacio para elementos subjetivos, incluida la imaginación científica. Sostiene que estas influencias entre pares, conocidas como themata, no solo no obstaculizan el progreso científico, sino que también sirven como un conducto para nuevos descubrimientos científicos. El objetivo del artículo es obtener una comprensión integral de su impacto en la academia y la investigación científica, investigando su posible convergencia o divergencia (...) con otros marcos cognitivos en la filosofía de la ciencia, como las categorías de Kant, los paradigmas de Kuhn y los programas de investigación de Lakatos. Al comparar los themata con estos marcos bien establecidos comúnmente utilizados para desentrañar el conocimiento y la investigación científica, este estudio tiene como objetivo aclarar posibles confusiones y profundizar nuestra comprensión de la influencia a menudo pasada por alto o subestimada ejercida por los themata en la ciencia. En un sentido específico, esta investigación destaca el papel vital desempeñado por la imaginación y las estructuras de pensamiento preexistentes en la formulación y avance de teorías científicas. A través de este análisis, se proporciona una comprensión integral de la esencia de los themata, destacando la importancia de reconocer y comprender los themata como componentes esenciales de la investigación científica en ciertos momentos. Como resultado, esta investigación refuerza la validez de la afirmación, objeto de debate continuo, de que los datos empíricos, la experiencia matemática o el razonamiento lógico por sí solos no pueden suplantar a estos componentes integrales.

The purpose of this chapter is to describe what we see as several important new directions for philosophy of medicine. This recent work (i) takes existing discussions in important and promising new directions, (ii) identifies areas that have not received sufficient and deserved attention to date, and/or (iii) brings together philosophy of medicine with other areas of philosophy (including bioethics, philosophy of psychiatry, and social epistemology). To this end, the next part focuses on what we call the “epistemological turn” in (...) recent work in the philosophy of medicine; the third part addresses new developments in medical research that raise interesting questions for philosophy of medicine; the fourth part is a discussion of philosophical issues within the practice of diagnosis; the fifth part focuses on the recent developments in psychiatric classification and scientific and ethical issues therein, and the final part focuses on the objectivity of medical research.

The Fifth Element (1997) is a French science-fiction film in English, directed and co-written by Luc Besson. The title and the plot of the film refer to a central notion of Greek philosophy, that is, pemptousia, or quintessence. Pre-Socratic philosophers such as Thales, Anaxagoras, Anaximenes and others, were convinced that all natural beings – in fact, nature itself – consist in four primary imperishable elements or essences (ousiai), i.e., fire, earth, water, and air. To these four, Aristotle added aether, a (...) fifth essence (pemptousia). The introduction of aether gave birth to a great tradition in late Antique and Medieval philosophy, and eventually it came to signify not an additional primary element, but the core-essence of all beings, their fundamental ontological structure. Besson’s film draws its inspiration on this philosophical tradition but its cinematographic rendering of the concept of Quintessence is typical of the contemporaneous views on the core characteristics of matters. The modernity that stimulates the film is equally anti-transcendentalist and anti-essentialist. Thus, the fifth element of the film is existentially personified and genderized making the traditional philosophical significance of the term to be adjusted by modernity in an immanent and temporal context where in addition aesthetics plays a crucial role.

Professor Fletcher challenges the traditional account of the development of tort doctrine as a shift from an unmoral standard of strict liability for directly causing harm to a moral standard based on fault. He then sets out two paradigms of liability to serve as constructs for understanding competing ideological viewpoints about the proper role of tort sanctions. He asserts that the paradigm of reciprocity, which looks only to the degree of risk imposed by the parties to a lawsuit on each (...) other, and to the existence of possible excusing conditions, provides greater protection of individual interests than the paradigm of reasonableness, which assigns liability instrumentally on the basis of a utilitarian calculus. Finally, Professor Fletcher examines stylistic differences between the two paradigms which may explain the modern preference for the paradigm of reasonableness. (shrink)

Radical empiricism is the view that a person's experiences (sensory and introspective), or a person's observations, constitute the person's evidence. This view leads to epistemic self-defeat. There are three arguments, concerning respectively: (1) epistemic starting points; (2) epistemic norms; (3) terms of epistemic appraisal. The source of self-defeat is traced to the fact that empiricism does not count a priori intuition as evidence (where a priori intuition is not a form of belief but rather a form of seeming, specifically intellectual (...) as opposed to sensory). Moderate rationalism, by contrast, avoids self-defeat. (shrink)

Scientific essentialism is the view that some necessities can be known only with the aid of empirical science. The thesis of the paper is that scientific essentialism does not extend to the central questions of philosophy and that these questions can be answered a priori. The argument is that the evidence required for the defense of scientific essentialism is reliable only if the intuitions required by philosophy to answer its central questions is also reliable. Included is an outline of a (...) modal reliabilist theory of basic evidence and a concept-possession account of the reliability of a priori intuition. (shrink)

This paper provides a defense of two traditional theses: the Autonomy of Philosophy and the Authority of Philosophy. The first step is a defense of the evidential status of intuitions (intellectual seemings). Rival views (such as radical empiricism), which reject the evidential status of intuitions, are shown to be epistemically self-defeating. It is then argued that the only way to explain the evidential status of intuitions is to invoke modal reliabilism. This theory requires that intuitions have a certain qualified modal (...) tie to the truth. This result is then used as the basis of the defense of the Autonomy and Authority theses. The paper closes with a defense of the two theses against a potential threat from scientific essentialism. (shrink)

The topic of a priori knowledge is approached through the theory of evidence. A shortcoming in traditional formulations of moderate rationalism and moderate empiricism is that they fail to explain why rational intuition and phenomenal experience count as basic sources of evidence. This explanatory gap is filled by modal reliabilism -- the theory that there is a qualified modal tie between basic sources of evidence and the truth. This tie to the truth is then explained by the theory of concept (...) possession: this tie is a consequence of what, by definition, it is to possess (i.e., to understand) one’s concepts. A corollary of the overall account is that the a priori disciplines (logic, mathematics, philosophy) can be largely autonomous from the empirical sciences. (shrink)

The concept of interactional expertise – characterized by sociologists Harry Collins and Robert Evans as the ability to speak the language of a discipline without the corresponding ability to practice – can serve as a powerful way of breaking down expert/non-expert dichotomies and providing a role for new voices in specialist communities. However, in spite of the vast uptake of this concept and its potential to fruitfully address many important issues related to scientific expertise, there has been surprisingly little critical (...) analysis of it. We seek to remedy this situation by considering potential benefits of interactional expertise and the ways in which the current conception can – and cannot – realize those benefits. In particular, we argue that interactional expertise hasn’t reached its full potential for addressing who ought to be involved in scientific research and decision-making, largely owing to an unnecessarily restrictive way of operationalizing the concept. In its place, we offer a broader, more pluralistic account of interactional expertise – one that is in line with the original spirit of the concept, but also captures the diversity that we see as being an important aspect of interactional experts and the value they can bring to the table.

Broadening access to both computational and educational resources is crit- ical to diffusing machine learning (ML) innovation. However, today, most ML resources and experts are siloed in a few countries and organizations. In this article, we describe our pedagogical approach to increasing access to applied ML through a massive open online course (MOOC) on Tiny Machine Learning (TinyML). We suggest that TinyML, applied ML on resource-constrained embedded devices, is an attractive means to widen access because TinyML leverages low-cost and globally (...) accessible hardware and encourages the development of complete, self-contained applications, from data collection to deployment. To this end, a collaboration between academia and industry produced a four part MOOC that provides application-oriented instruction on how to develop solutions using TinyML. The series is openly available on the edX MOOC platform, has no prerequisites beyond basic programming, and is designed for global learners from a variety of backgrounds. It introduces real-world applications, ML algorithms, data-set engineering, and the ethi- cal considerations of these technologies through hands-on programming and deployment of TinyML applications in both the cloud and on their own microcontrollers. To facili- tate continued learning, community building, and collaboration beyond the courses, we launched a standalone website, a forum, a chat, and an optional course-project com- petition. We also open-sourced the course materials, hoping they will inspire the next generation of ML practitioners and educators and further broaden access to cutting-edge ML technologies. (shrink)

It is argued that the distinction between the mental and the nonmental is at bottom logical. The paper begins by sketching and defending a theory of intensional logic in which the notion of logically and metaphysically basic relations (called connections) can be defined. This notion is then employed in an analysis of intentionality: a connection is intentional iff it can contingently connect some individual to some proposition or concept independently of whether it connects the individual to some necessarily equivalent proposition (...) or concept. After potential counterexamples have been explained away, the paper then extends the analysis to a general analysis of mentality. Finally, a "transcendental" argument is given for the thesis that at least some mental relations must be logically and metaphysically basic. (shrink)

This paper argues that participation in an intimate relationship can generate additional or stronger reasons for one to act paternalistically toward the intimate. Moreover, participation in such a relationship can also weaken or cancel some of the presumptive reasons of respect one would otherwise have not to interfere.

Intellectualism about human virtue is the thesis that virtue is knowledge. Virtue intellectualists may be eliminative or reductive. If eliminative, they will eliminate our conventional vocabulary of virtue words-'virtue', 'piety', 'courage', etc.-and speak only of knowledge or wisdom. If reductive, they will continue to use the conventional virtue words but understand each of them as denoting nothing but a kind of knowledge (as opposed to, say, a capacity of some other part of the soul than the intellect, such as the (...) will or the appetites). Virtue intellectualists may be pluralists or monists. If pluralist, they identify the virtues with distinct kinds of knowledge. If monist, they identify all the virtues with one and the same kind of knowledge. In a number of dialogues-including the Euthyphro, Apology, Charmides, Euthydemus, Laches, Lysis, Protagoras, and Republic I-Socrates gives arguments that support Reductive Monist Intellectualism (RMI) about human virtue. I disarm an influential objection to RMI as the correct interpretation of Socrates. (shrink)

A close look at Frege's proof in "Foundations of Arithmetic" that every number has a successor. The examination reveals a surprising gap in the proof, one that Frege would later fill in "Basic Laws of Arithmetic".

Recent work in philosophy of language has raised significant problems for the traditional theory of propositions, engendering serious skepticism about its general workability. These problems are, I believe, tied to fundamental misconceptions about how the theory should be developed. The goal of this paper is to show how to develop the traditional theory in a way which solves the problems and puts this skepticism to rest. The problems fall into two groups. The first has to do with reductionism, specifically attempts (...) to reduce propositions to extensional entities-either extensional functions or sets. The second group concerns problems of fine grained content-both traditional 'Cicero'/'Tully' puzzles and recent variations on them which confront scientific essentialism. After characterizing the problems, I outline a non-reductionist approach-the algebraic approach-which avoids the problems associated with reductionism. I then go on to show how the theory can incorporate non-Platonic (as well as Platonic) modes of presentation. When these are implemented nondescriptively, they yield the sort of fine-grained distinctions which have been eluding us. The paper closes by applying the theory to a cluster of remaining puzzles, including a pair of new puzzles facing scientific essentialism. (shrink)

Slavery in Ancient Greece, Absolutist Monarchy in pre-modern Europe, and the European conquest of the New World strike us, from our contemporary perspective, as injustices on a massive scale. But given the impact of these large-scale historical activities on the particular course taken by Western history, they almost undeniably played an important role in the evolution of modern liberalism. Bernard Williams suggests a startling claim—that liberal universalists cannot condemn past injustices, because those injustices were necessary conditions of the development of (...) the modern liberalism that they affirm. This paper examines this possible objection to liberal universalists who greatly value their liberal way of life, paying particular attention to the lamentable necessities thesis: the claim that modern liberalism would not have come into existence but for the occurrence of past injustices. It motivates the lamentable necessities thesis, and argues that those who accept it, and greatly value modern liberalism, are precluded from regretting all-things-considered certain past injustices. Finally, it makes the case that liberal universalists who greatly value modern liberalism may condemn past injustices necessary to its emergence, even if they are unable to regret them in the relevant sense.

It also contains a fuller discussion of how to neutralize the threat of scientific essentialism to the autonomy of (...) philosophy. (shrink)

We investigate an enrichment of the propositional modal language L with a "universal" modality ■ having semantics x ⊧ ■φ iff ∀y(y ⊧ φ), and a countable set of "names" - a special kind of propositional variables ranging over singleton sets of worlds. The obtained language ℒ $_{c}$ proves to have a great expressive power. It is equivalent with respect to modal definability to another enrichment ℒ(⍯) of ℒ, where ⍯ is an additional modality with the semantics x ⊧ ⍯φ (...) iff Vy(y ≠ x → y ⊧ φ). Model-theoretic characterizations of modal definability in these languages are obtained. Further we consider deductive systems in ℒ $_{c}$ . Strong completeness of the normal ℒ $_{c}$ logics is proved with respect to models in which all worlds are named. Every ℒ $_{c}$ -logic axiomatized by formulae containing only names (but not propositional variables) is proved to be strongly frame-complete. Problems concerning transfer of properties ([in]completeness, filtration, finite model property etc.) from ℒ to ℒ $_{c}$ are discussed. Finally, further perspectives for names in multimodal environment are briefly sketched. (shrink)

The paper investigates Ernst Cassirer’s structuralist account of geometrical knowledge developed in his Substanzbegriff und Funktionsbegriff. The aim here is twofold. First, to give a closer study of several developments in projective geometry that form the direct background for Cassirer’s philosophical remarks on geometrical concept formation. Specifically, the paper will survey different attempts to justify the principle of duality in projective geometry as well as Felix Klein’s generalization of the use of geometrical transformations in his Erlangen program. The second aim (...) is to analyze the specific character of Cassirer’s geometrical structuralism formulated in 1910 as well as in subsequent writings. As will be argued, his account of modern geometry is best described as a “methodological structuralism”, that is, as a view mainly concerned with the role of structural methods in modern mathematical practice.

This is the only complete logic for properties, relations, and propositions (PRPS) that has been formulated to date. First, an intensional abstraction operation is adjoined to first-order quantifier logic, Then, a new algebraic semantic method is developed. The heuristic used is not that of possible worlds but rather that of PRPS taken at face value. Unlike the possible worlds approach to intensional logic, this approach yields a logic for intentional (psychological) matters, as well as modal matters. At the close of (...) the paper, the origin of incompleteness in logic is investigated. The culprit is found to be the predication relation, a relation on properties and relations that is expressed in natural language by the copula. (shrink)

It is argued that, because of scientific essentialism, two currently popular arguments against the mind-body identity thesis -- the multiple-realizability argument and the Nagel-Jackson knowledge argument -- are unsatisfactory as they stand and that their problems are incurable. It is then argued that a refutation of the identity thesis in its full generality can be achieved by weaving together two traditional Cartesian arguments -- the modal argument and the certainty argument. This argument establishes, not just the falsity of the identity (...) thesis, but also the metaphysical possibility of disembodiment. (shrink)

Presented here is an argument for the existence of universals. Like Church's translation- test argument, the argument turns on considerations from intensional logic. But whereas Church's argument turns on the fine-grained informational content of intensional sentences, this argument turns on the distinctive logical features of 'that'-clauses embedded within modal contexts. And unlike Church's argument, this argument applies against truth-conditions nominalism and also against conceptualism and in re realism. So if the argument is successful, it serves as a defense of full (...) ante rem realism. The argument emphasizes the need for a unified treatment of intensional statements -- modal statements as well as statements of assertion and belief. The larger philosophical moral will be that ante rem universals are uniquely suited to carry a certain kind of modal information. Linguistic entities, mind-dependent universals, and instance-dependent universals are incapable of serving that function. (shrink)
