In response to scholarship which has shown that seventeenth-century Scottish scholasticism was influenced by John Duns Scotus (1265/66–1308), Jean-Pascal Anfray has argued that Scottish scholasticism was only indirectly influenced by Scotism, especially by Jesuit thinkers like Francisco Suárez (1548–1618), using the Aberdeen Doctor James Sibbald (1595–1647) and his theory of the body-soul composite as a litmus test. In reply to Anfray’s claims, this article undertakes three interconnected tasks. First, it renews calls for philosophical Scotism to be defined according to a (...) principles-based approach focusing on Scotus’s metaphysics of essence in contrast to a quasi-falsificationist approach. Second, it shows how Sibbald adopts the Scotist metaphysics of essence over the very different Suárezian metaphysics of essence. Third, it demonstrates how Sibbald endorses Scotus’s qualified pluralism in accounting for the body-soul composite. Sibbald thus turns out to be more directly Scotist (and less Suárezian) than first thought. (shrink)

Over 35 years, Daniel Dennett has articulated a rich and expansive philosophical outlook. There have been elaborations, refinements, and changes of mind, exposi- tory and substantive. This makes him hard to pin down. Does he, for example, think intentional states are real? In places, he sounds distinctly instrumentalist; elsewhere, he avows realism, ‘sort of’. What is needed is a map, charting developments and tracing dialectical threads through his extensive writings and the different regions of his thought. This is what (...) class='Hi'>Matthew Elton’s impressive book supplies.

Matthew Soteriou provides an original philosophical account of sensory and cognitive aspects of consciousness. He explores distinctions of temporal character in our mental lives--especially in relation to the exercise of agency--and illuminates the more general issue of the place and role of mental action in the metaphysics of mind.

A popular belief sustains that being honest is not profitable. John Baines sustains that morality is a powerful tool for success in life. Morals for the 21st Century is not a simple reformulation of natural morals, but an absolutely new proposal of morals in which the author categorically asserts and presents experiments to the effect that morality is firmly set on scientific premises, for the first time breaking the ideological and theological bases which have always served as their support. (...) The morals proposed by John Baines are situated in the world of the laws of energy, that is, in the strict domain of physics. Every person that complies with this moral code, will be complying with himself: by respecting this moral code, he will be respecting himself: sowing the laws of this moral code in the earth of his being, he will harvest multiplying each grain, proving the benefits of complying with this eternal order of things, without need of fear or faith. "Genuine morals correspond to the harmonization guidelines of the Universe and Nature, so that those who carefully observe their laws will always be successful..." Also available in Spanish, Arabic.

In an earlier paper I argued that we do not have an objective conception of best interests and that this is a particular problem because the courts describe that they use an ‘…objective approach or test. That test is the best interests of the patient’ when choosing for children. I further argued that there was no obvious way in which we could hope to develop an objective notion of best interests. As well as this, I argued that a best-interest-based approach (...) was a particular problem around the time of death of some children. A response from a legal perspective argued that, while there is not a clear conception of objective best interests, the courts have a well-described approach to finding a child's objective best interests. In this paper, I argue that without clear agreement on an objective conception of best interests, the courts are unable to locate an objective sense of best interests and that the solutions do not solve the problems that were identified in the initial paper ‘Death and best interests’.

It is commonly held that the experiences involved in cases of perception, illusion and hallucination all have the same nature. Disjunctivists deny this. They maintain that the kind of experience you have when you perceive the world isn’t one you could be having if you were hallucinating. A number of important debates in the philosophy of mind and epistemology turn on the question of whether this disjunctivist view is tenable. This is the first book-length introduction to this contested issue. (...) class='Hi'>Matthew Soteriou explains the accounts of perception that disjunctivists seek to defend, such as naïve realism, and the accounts to which they are opposed, such as sense-datum theories and representationalist theories. He goes on to introduce and assess key questions that arise in these debates: Is disjunctivism consistent with what has been established by the science of perception? Does introspective reflection support naïve realism? Can disjunctivism be motivated by appeal to the role that perception plays in enabling us to think demonstratively about mind-independent objects and qualities in our environment? Does disjunctivism offer the best account of perceptual knowledge? What can disjunctivists say about the nature of hallucination and illusion? Including chapter summaries, annotated further reading and a glossary, this book is an ideal starting point for anyone studying disjunctivism for the first time, as well as for more advanced students and researchers.

In Feminism and the Power of Law Carol Smart argued “law must also be tackled at the conceptual level if feminist discourses are to take a firmer root” (Smart in Feminism and the power of law, Routledge, London, 1989, 5). In Canada, the Women’s Legal Education and Action Fund (LEAF) ’tackled‘ the concept of comparison in the age equality case of Withler v Canada, 2008 BCCA 539. Rejecting ’similarly situated ‘(or ’groups‘) comparison as inconsistent with substantive equality, LEAF advocated a (...) “contextual” approach to import gender into the Withler frame. However, LEAF did not identify a male comparator even though all of the plaintiffs were women. Accordingly, it is unclear whether LEAF’s contextual approach obviates comparison, permits comparing some women to other women, or is synonymous with ‘grounds’ comparison. I argue LEAF could have named the patriarchal state as the male comparator in Withler, thereby aligning their contextual approach with ‘grounds’ comparison and offering substantive equality a ’firmer root’.

In this paper I argue that if one subscribes to dispositionalism — the view that natural properties are irreducibly dispositional in character — then one ought to favour a Platonic view of properties. That is, dispositionalists ought to view properties as transcendent universals. I argue for this on the grounds that only with transcendent universals in play can two central dispositionalist platitudes be accounted for in a satisfactory way. Given that dispositionalism is becoming an increasingly influential view in the metaphysics (...) of science, my argument, if successful, suggests that Platonism will see something of a revival in contemporary metaphysics. This new kind of Platonism is shown to have some striking metaphysical and epistemological consequences. (shrink)

We advance a theory of inductive inference designed to predict the conditional probability that certain natural categories satisfy a given predicate given that others do (or do not). A key component of the theory is the similarity of the categories to one another. We measure such similarities in terms of the overlap of metabolic activity in voxels of various posterior regions of the brain in response to viewing instances of the category. The theory and similarity measure are tested against averaged (...) probability judgments elicited from a separate group of subjects. Fruit serve as categories in the present experiment; results are compared to earlier work with mammals. (shrink)

In Measuring the Immeasurable Mind: Where Contemporary Neuroscience Meets the Aristotelian Tradition, Matthew Owen argues that despite its nonphysical character, it is possible to empirically detect and measure consciousness. -/- Toward the end of the previous century, the neuroscience of consciousness set its roots and sprouted within a materialist milieu that reduced the mind to matter. Several decades later, dualism is being dusted off and reconsidered. Although some may see this revival as a threat to consciousness science aimed at (...) measuring the conscious mind, Owen argues that measuring consciousness, along with the medical benefits of such measurements, is not ruled out by consciousness being nonphysical. Owen proposes the Mind-Body Powers model of neural correlates of consciousness, which is informed by Aristotelian causation and a substance dualist view of human nature inspired by Thomas Aquinas, who often followed Aristotle. In addition to explaining why there are neural correlates of consciousness, the model provides a philosophical foundation for empirically discerning and quantifying consciousness. En route to presenting and applying the Mind-Body Powers model to neurobiology, Owen rebuts longstanding objections to dualism related to the mind-body problem. With scholarly precision and readable clarity, Owen applies an oft forgotten yet richly developed historical vantage point to contemporary cognitive neuroscience. (shrink)

Children ‘born of war’ refer to people of any age conceived as the result of sexual violence at the hands of armed forces or groups during war, displacement, genocide or military occupation. Due to the circumstances of their birth, children ‘born of war’ can experience social stigma, discrimination and exclusion, resulting in diminished life chances and opportunities. At the same time, children ‘born of war’ fall through the cracks of global policy frameworks. In this article, we explore the reasons for (...) this, arguing that the nature of the harm these children endure renders their status as a victim group elusive. We propose a survivor-centred approach drawing on the lived experiences of children ‘born of war’. The approach recognizes the agency of children and draws attention to their expressed desire to contribute to, and participate in, processes of social reconstruction and reconciliation. (shrink)

Assertion is governed by an epistemic norm requiring knowledge. This idea has been hotly debated in recent years, garnering attention in epistemology, philosophy of language, and linguistics. This chapter presents and extends the main arguments in favor of the knowledge norm, from faulty conjunctions, several conversational patterns, judgments of permission, excuse, and blame, and from showing how. (Paired with a chapter by Peter J. Graham and Nikolaj J. L. L. Pedersen, "Knowledge is Not Our Norm of Assertion.").

"What is gender? More importantly, what should gender look like in the 21st century?

In Zizek and Politics, Geoff Boucher and Matthew Sharpe go beyond standard introductions to spell out a new approach to reading Zizek, one that can be highly critical as well as deeply appreciative. They show that Zizek has a raft of fundamental positions that enable his theoretical positions to be put to work on practical problems. Explaining these positions with clear examples, they outline why Zizek's confrontation with thinkers such as Derrida, Foucault and Deleuze has so radically changed how (...) we think about society. They then go on to track Zizek's own intellectual development during the last twenty years, as he has grappled with theoretical problems and the political climate of the War on Terror. This book is a major addition to the literature on Zizek and a crucial critical introduction to his thought. (shrink)

Principlism, the bioethical theory championed by Tom Beauchamp and James Childress, is centered on the four moral principles of beneficence, non-maleficence, respect for autonomy, and justice. Two key processes related to these principles are specification—adding specific content to general principles—and balancing—determining the relative weight of conflicting principles. I argue that both of these processes necessarily involve an appeal to human goods and evils, and therefore require a theory of the good. A significant problem with principlism is that it lacks a (...) theory of the good and consequently does not have an adequate solution to the problems of specification and balancing. My conclusion is that principlism must adopt some account of human well-being in order to be a satisfactory bioethical framework. (shrink)

I argue that Sarah Sawyer's and Herman Cappelen's recent accounts of how speakers talk and think about the same concept or topic even when their understandings of that concept or topic substantially diverge risk multiplying our metasemantic categories unnecessarily and fail to prove explanatory. When we look more closely at our actual practices of samesaying, we find that speakers with seemingly incompatible formulations of a subject matter take one another to samesay when they are attempting to arrive at a correct (...) understanding of that subject matter. These speakers adopt what I call a prospective externalist perspective on the subject matter in question. I then argue that there are contexts where judgments of samesaying are more routinely defeated because speakers are taking up a perspective I call retrospective internalism. From this perspective, speakers are aiming to render maximally intelligible the linguistic behavior of other speakers that appear to them to deviate from their own. Whether or not we count speakers as samesaying with us will therefore depend on the kind of the perspective we adopt. Different perspectives, it will turn out, often yield different verdicts. On my perspective-based approach, there is no need to hypostatize or inflate our metasemantic taxonomies. (shrink)

One of the liveliest debates about cognition concerns whether our cognition sometimes extends beyond our brains and bodies. One party says Yes, another No. This paper shows that debate between these parties has been epistemologically confused and requires reorienting. Both parties frequently appeal to empirical considerations and to extra-empirical theoretical virtues to support claims about where cognition is. These things should constrain their claims, but cannot do all the work hoped. This is because of the overlooked fact, uncovered in this (...) paper, that we could never distinguish the rival views empirically or by typical theoretical virtues. I show this by drawing on recent work on testing, predictive accuracy, and theoretical virtues. The recommendation to emerge is that we step back from debate about where cognition is, to the epistemology of what cognition is. (shrink)

Responses to public health emergencies can entail difficult decisions about restricting individual liberties to prevent the spread of disease. The quintessential example is quarantine. While isolating sick patients tends not to provoke much concern, quarantine of healthy people who only might be infected often is controversial. In fact, as the experience with severe acute respiratory syndrome (SARS) shows, the vast majority of those placed under quarantine typically don't become ill. Efforts to enforce involuntary quarantine through military or police powers also (...) can backfire, stoking both panic and disease spread. Yet quarantine is part of a limited arsenal of options when effective treatment or prophylaxis is not available, and some evidence suggests it can be effective, especially when it is voluntary, home-based and accompanied by extensive outreach, communication and education efforts. Even assuming that quarantine is medically effective, however, it still must be ethically justified because it creates harms for many of those affected. Moreover, ethical principles of reciprocity, transparency, non-discrimination and accountability should guide any implementation of quarantine. (shrink)

Contemporary scholarship concerning science diplomacy is increasingly taking a historical approach. In our introduction to this special issue, we argue that this approach promises insight into science diplomacy because of the tools historians of science bring to their work. In particular, we observe that not only are historians of science currently poised to chart the diplomatic aspects involved in the transnational circulation of technoscientific knowledge, materials, and expertise. They are ready to bring critical global analysis to an important phenomenon that (...) has too often been treated as a benign diplomacy device deployed by the Global North without equal reference to the Global South. Through cases discussed in the articles of the special issue, however, we see that historically, in the Global South as well as the Global North, science diplomacy has often functioned to mediate the circulation of technoscientific knowledge and materials, and its historical study helps to better illuminate the resulting knowledge-power nexus.

This paper proposes a new and testable view about the nature of species and other evolving lineages, according to which they are feedback systems. On this view, it is a mistake to think gene flow, niche sharing, and trait frequency similarities between populations are among variables that interact to cause some further downstream variable that distinguishes evolving lineages from each other, some sort of “species cohesion” for example. Instead, gene flow, niche sharing, similarities between populations, and other causal variables feed (...) into each other—instances of these at earlier times help cause instances of these same variables at later times. And any lineage-identifying cohesion just is the recurrence or cycling of these feedback relations within metapopulations over generations. Such cohesion can then be represented as variable M within multi-dimensional variable spaces, where values of M vary dynamically with the frequency and magnitude of feedback relations. Related conditions for being a species or other evolving lineage are then clarified. To argue for the development and testing of this view, the paper shows how it improves upon others. (shrink)

Over the past few decades, significant advances have been made in public engagement with, and the democratization of, science and technology. Despite notable successes, such developments have often struggled to enhance public trust, avert crises of expertise and democracy, and build more socially responsive and responsible science and innovation. A central reason for this is that mainstream approaches to public engagement harbor what we call “residual realist” assumptions about participation and publics. Recent coproductionist accounts in science and technology studies offer (...) an alternative way of seeing participation as coproduced, relational, diverse, and emergent but have been somewhat reluctant to articulate what this means in practice. In this paper, we make this move by setting out a new framework of interrelating paths and associated criteria for remaking public participation with science and democracy in more experimental, reflexive, anticipatory, and responsible ways. This framework comprises four paths to: forge reflexive participatory practices that attend to their framings, emergence, uncertainties, and effects; ecologize participation through attending to the interrelations between diverse public engagements in wider systems; catalyze practices of anticipatory reflection to bring about responsible democratic innovations; and reconstitute participation as constitutive of systems of technoscience and democracy.

I defend affirmative action on the ground that it increases certain people’s ability to exercise their basic liberties, rather than because it rectifies injustice in the narrow context of educational admission procedures. I present this justification using a Rawlsian contractualist framework to forge a “nonideal principle of justice.” Drawing on social science, I argue that this principle supports affirmative-action policies like those in the contemporary U.S., and blocks the objection that such policies are unfair. In closing, I show how my (...) account can be used to refine some features of contemporary affirmative-action policies, and I reflect more generally on the value of nonideal principles of justice for tackling exigent topics.

In 2019 public trust in politicians was at an all-time low in many parts of the world. Then again, it had been low for quite some time.1 Public trust in epistemic authority is a more complicated matter.

But worries about the erosion of epistemic standards in public (...) discourse are easily overstated, and some polling data have shown that publics are not as distrustful of experts as we might fear.2Nonetheless, there are some political and social...

The rapidly expanding field of critical animal studies now offers a myriad of theoretical and philosophical positions from which to choose. This timely book provides an overview and analysis of the most influential of these trends. Approachable and concise, it is intended for readers sympathetic to the project of changing our ways of thinking about and interacting with animals yet relatively new to the variety of philosophical ideas and figures in the discipline. It uses three rubrics—identity, difference, and indistinction—to differentiate (...) three major paths of thought about animals. The identity approach aims to establish continuity among human beings and animals so as to grant animals equal access to the ethical and political community. The difference framework views the animal world as containing its own richly complex and differentiated modes of existence in order to allow for a more expansive ethical and political worldview. The indistinction approach argues that we should abandon the notion that humans are unique in order to explore new ways of conceiving human-animal relations. Each approach is interrogated for its relative strengths and weaknesses, with specific emphasis placed on the kinds of transformational potential it contains. (shrink)

Here, I consider Derek Parfit’s Normativity Objection to naturalist realism, according to which normative-natural property or fact reductions are “conceptually excluded”. While a lot of philosophers inclined toward non-naturalism share this view or something close to it, plenty of philosophers remain unconvinced, and the literature offers little guidance to the perplexed. I suggest a way to improve the argument – indeed, I think it is the best and perhaps only plausible way to make good on the claim of conceptual exclusion. (...) But the improved argument relies on the highly controversial claim that normative cognition is transparentin the following sense: normative concepts reveal the nature of the properties they aim to ascribe. This nature, the argument continues, is inconsistent with naturalist strictures. (shrink)

In ‘Computing Machinery and Intelligence’, Turing, sceptical of the question ‘Can machines think?’, quickly replaces it with an experimentally verifiable test: the imitation game. I suggest that for such a move to be successful the test needs to be relevant, expansive, solvable by exemplars, unpredictable, and lead to actionable research. The Imitation Game is only partially successful in this regard and its reliance on language, whilst insightful for partially solving the problem, has put AI progress on the wrong foot, prescribing (...) a top-down approach for building thinking machines. I argue that to fix shortcomings with modern AI systems a nonverbal operationalisation is required. This is provided by the recent Animal-AI Testbed, which translates animal cognition tests for AI and provides a bottom-up research pathway for building thinking machines that create predictive models of their environment from sensory input.

Although Kant defends a cosmopolitan ideal, his philosophy is problematically vague regarding how to achieve it, which lends support to the empty formalism charge. How Kant would respond to the crisis in Syria reveals that judgement plays too central a role, because Kantian principles lead to equally reasonable but opposite conclusions on how to weigh the duty of hospitality to refugees against a state’s duty to its own citizens, the right of prevention towards ISIS against the duty not to harm (...) non-combatants, and the responsibility to protect the people of Syria against the duty of non-interference in its internal affairs.

Prioritarianism is an ethical theory that gives extra weight to the well-being of the worse off. In contrast, dominant policy-evaluation methodologies, such as benefit-cost analysis, cost-effectiveness analysis, and utilitarianism, ignore or downplay issues of fair distribution. Based on a research group founded by the editors, this important book is the first to show how prioritarianism can be used to assess governmental policies and evaluate societal conditions. This book uses prioritarianism as a methodology to evaluate governmental policy across a variety of (...) policy domains: taxation, health policy, risk regulation, education, climate policy, and the COVID-19 pandemic. It is also the first to demonstrate how prioritarianism improves on GDP as an indicator of a society's progress over time. Edited by two senior figures in the field with contributions from some of the world's leading economists, this volume bridges the gap from the theory of prioritarianism to its practical application.

A popular version of anti-Humeanism is one that views fundamental properties as being irreducibly dispositional in nature, and it is a view to which I am attracted. Proponents of this view typically object to Humean regularity theories of laws on the basis that they do not explain why our world is regular rather than chaotic from moment to moment. It is thought that, for this reason, Humeanism does not provide firm enough foundations for induction. However, in this paper I argue (...) that it is far from clear how these anti-Humeans can themselves explain this regularity. This is because it is far from clear how they can explain why the entities in our world do not change their dispositional properties arbitrarily over time. This is a neglected problem, which I call the retention problem. In an attempt to solve this problem, several naturalistic explanations of retention are explored. Unfortunately, none of these explanations is free of problems, showing that dispositional forms of anti-Humeanism may not have as many advantages as some have assumed where the problem of induction is concerned.

The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Recent arguments over whether certain public health interventions should be mandatory raise questions about what counts as a "mandate." A mandate is not the same as a mere recommendation or the standard of practice. At minimum, a mandate should require an active opt-out and there should be some penalty for refusing to abide by it. Over-loose use of the term "mandate" and the easing of opt-out provisions could eventually pose a risk to the gains that truly mandatory public health interventions, (...) such as childhood vaccines, have provided over the last 50 years. Already, confusion about what counts as a mandate, and about what criteria should be used to determine when a public health intervention should be implemented as a mandate, has led to some inappropriate public policy decisions. For instance, by any reasonable criteria, the yearly influenza vaccine should be mandatory for health care workers. To enforce this mandate, those who refuse vaccination should be required to sign a waiver, and patients - especially those at high risk from flu - should be informed when they receive care from unvaccinated practitioners.

In modal subordination, a modal sentence is interpreted relative to a hypothetical scenario introduced in an earlier sentence. In this paper, I argue that this phenomenon reflects the fact that the interpretation of modals is an ANAPHORIC process. Modal morphemes introduce sets of possible worlds, representing alternative hypothetical scenarios, as entities into the discourse model. Their interpretation depends on evoking sets of worlds recording described and reference scenarios, and relating such sets to one another using familiar notions of restricted, preferential (...) quantification. This proposal relies on an extended model of environments in dynamic semantics to keep track of associations between possible worlds and ordinary individuals; it assumes that modal meanings and other lexical meanings encapsulate quantification over possible worlds. These two innovations are required in order for modals to refer to sets of possible worlds directly as static objects in place of the inherently dynamic objects—quite different from the referents of pronouns and tenses—used in previous accounts. The simpler proposal that results offers better empirical coverage and suggests a new parallel between modal and temporal interpretation. (shrink)

I offer an account of truth that combines elements of deflationism and traditional correspondence theories. We need such an intermediary account, I argue, in order to adequately answer two kinds of questions: "Why do we find it obvious that 'p' is true iff p?" and "Why is it contingent that 'p' is true iff p?" If what it is for 'p' to be true is explained by simply saying that p, as the deflationist claims, it is hard to see how (...) it could be contingent that 'p' is true iff p. But if it is claimed instead that what it is for a sentence to be true is for it to correspond to a fact, we still need some explanation of why 'p's correspondence with reality insure that p, and vice versa. What we need, I claim, is to recognize a structure to truth: truth for sentences, utterances, and other non-propositional entities depends on, and is analyzable in terms of, the expression of true propositions. Propositional truth can then be treated as insubstantial, as deflationary, and truth for other entities as substantial, consisting of correspondence to a fact . ;This account of truth, which I call Weak Deflationism, anchors the dissertation. In an introductory chapter, I give a partial defense of realism about propositions and properties, later defending Platonism against attacks by David Lewis. After formulating Weak Deflationism, I examine its implications for such matters as the "absurd comparison" objection, the truthmaker project in ontology, and non-factualist theories in metaethics. In a final chapter, I provide a Kripke-inspired modification of Weak Deflationism aimed to avoid liar-like paradox. Premised on a distinction between propositions that predicatively involve truth, i.e., truth-dependent propositions, and those that do not, truth-independent propositions, I argue that truth for the latter is deflationary and that truth for the former consists in being determined by the totality of truth-independent fact. Falsity is understood as truth of the negation. Liars are then counted neither true nor false, and paradox is averted. (shrink)

The general issue addressed in this dissertation is: what do the models of formal model-theoretic semantics represent? In chapter 2, I argue that those of first-order classical logic represent meaning assignments in possible worlds. This motivates an inquiry into what the interpretations of first-order quantified model logic represent, and in Chapter 3 I argue that they represent meaning assignments in possible universes of possible worlds. A possible universe is unpacked as one way model reality might be. The problem arises here (...) as to how we are to understand the distinction between the actual and the possible as it relates to modal reality. ;Along with the development of the main arguments in Chapters 2 and 3, the dissertation assesses the status of semantic accounts or logical properties and relations. Specifically, what does the model-theoretic account of a logically possible situation add to the syntactic account ? ;Proofs of invalidity in terms of the models of formal semantics do not establish that it is possible for the premises to be true and the conclusion false, since a formal model is merely given by a consistent set of sentences. Unless there is some way to generate a non-formal model from a formal one, such proofs do not really go beyond syntactic notions. The dissertation ends by concluding that there is no way to generate a non-formal model from a formal one without relying on logical intuitions that are syntactical. ;Hence efforts to construct a semantic basis for model logic independent of syntactic commitments are misguided. However, in classical logic the independence of the semantic account from the syntactic one is grounded on the intuition that it is metaphysically possible for there to be a denumerably infinite totality of objects.
