This paper looks at emergence in physical theories and argues that an appropriate way to understand socalled “emergent protectorates” is via the explanatory apparatus of the renormalization group. It is argued that mathematical singularities play a crucial role in our understanding of at least some well-defined emergent features of the world.

One of the strongest strands in Nancy's philosophy is an attempt to rethink community and the very idea of the social in a way that does not ground these ideas in some individual subject or subjectivity. The fundamental argument of this book is that being is always 'being with', that 'I' is not prior to 'we', that existence is essentially co-existence. He thinks this being together, not as a comfortable enclosure in a pre-existing group, but as a mutual abandonment and (...) exposure to each other, one that would preserve the 'I' and its freedom in a mode of imagining community as neither a 'society of spectacle' nor via some form of 'authenticity'.

A singular thought about an object o is one that is directly about o in a characteristic way—grasp of that thought requires having some special epistemic relation to the object o, and the thought is ontologically dependent on o. One account of the nature of singular thought exploits a Russellian Structured Account of Propositions, according to which contents are represented by means of structured n-tuples of objects, properties, and functions. A proposition is singular, according to this framework, (...) if and only if it contains an object as a constituent. One advantage of the framework of Russellian Structured propositions is that it promises to provide a metaphysical basis for the notion of a singular thought about an object, grounding it in terms of constituency. In this paper, we argue that the attempt to ground the peculiar features of singular thoughts in terms of metaphysical constituency fails, and draw some consequences of our discussion for other debates.

Toward a theory of n-tuples of individuals and concepts as surrogates for Russellian singular propositions and singular concepts. Alonzo Church proposed a powerful and elegant theory of sequences of functions and their arguments as singular-concept surrogates. Church’s account accords with his Alternative (0), the strictest of his three competing criteria for strict synonymy. The currently popular objection to strict criteria like (0) on the basis of the Russell-Myhill paradox is here rebutted. As Church recognized, Russell-Myhill is not (...) a problem specifically for Alternative (0). Rather it is a disproof of unrestricted concept comprehension. Unrestricted comprehension is also inconsistent with facts about sets of properties. It is demonstrated furthermore that the principal rival conception of propositions--propositions conceived as classes of possible worlds--is subject to a fatal philosophical collapse: It follows on that conception, given that each of us is fallible, that everyone believes everything. Although it is far superior to its principal rival conception, Church’s proposed theory is vulnerable under (0) to a version of Russell’s notorious Gray’s /Elegy/ objection. Some amendments to Church’s proposal are proffered that address Russell’s objection, including an amendment first proposed in the present author’s /Frege’s Puzzle/ (1986). Church’s response (personal correspondence) is considered. (shrink)

In this introduction, I consider different problems posed by the use of singular terms in fiction (section 1), paying especial attention to proper names and, in particular, to names of real people, places, etc. As we will see (section 2), descriptivist and Millian theories of reference face different kinds of problems in explaining the use of fictional names in fiction-related contexts. Moreover, the task of advancing a uniform account of names in these contexts—an account which deals not only with (...) fictional names but also with “real” names—will prove to be very hard no matter whether we favour realist or antirealist intuitions about fictional discourse (section 3). Section 4 offers an overview of the content of this volume, with emphasis on the discussion between Manuel García-Carpintero and Stacie Friend about the meaning of “real” names in fiction-related contexts, the main topic of the Third Blasco Disputatio.

De re or singular thoughts are, intuitively, those essentially or constitutively about a particular object or objects; any thought about different objects would be a different thought. How should a philosophical articulation or thematization of their nature look like? In spite of extended discussion of the issue since it was brought to the attention of the philosophical community in the late fifties by Quine (1956), we are far from having a plausible response. Discussing the matter in connection with the (...) status of the Kripkean category of the contingent a priori, Donnellan (1979) argued that what can be properly classified as knowable a priori about utterances like those involving ‘one meter’ or ‘Neptune’ famously proposed by Kripke (1980) cannot be the very same singular content that is contingent he distinguished to that end between knowing a true proposition expressed by an utterance, and knowing that an utterance expresses a true proposition. Evans (1979) replied that, for a very specific sort of cases involving “descriptive names”, a related proto-two-dimensionalist account should be preferred, on which it is not the singular contingent content, but rather a general descriptive one which is knowable a priori. In a series of papers, Robin Jeshion (2000, 2001) has recently attacked Donnellan's proposal, arguing in favour of the most straightforward interpretation of Kripke's claim: in the relevant cases, the very same singular content can be both contingent and knowable a priori. This paper appeals to a generalized version of two-dimensional semantics to advance an account of the Kripkean cases along the lines of Evans's, and argues that Jeshion's compelling arguments against Donnellan's view do not apply to this version.

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the “singularity”. The basic argument here was set out by the statistician I.J. Good in his 1965 article “Speculations Concerning the First Ultraintelligent Machine”: Let an ultraintelligent machine be defined as a machine that can far (...) surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an “intelligence explosion”, and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. The key idea is that a machine that is more intelligent than humans will be better than humans at designing machines. So it will be capable of designing a machine more intelligent than the most intelligent machine that humans can design. So if it is itself designed by humans, it will be capable of designing a machine more intelligent than itself. By similar reasoning, this next machine will also be capable of designing a machine more intelligent than itself. If every machine in turn does what it is capable of, we should expect a sequence of ever more intelligent machines. This intelligence explosion is sometimes combined with another idea, which we might call the “speed explosion”. The argument for a speed explosion starts from the familiar observation that computer processing speed doubles at regular intervals. Suppose that speed doubles every two years and will do so indefinitely. Now suppose that we have human-level artificial intelligence 1 designing new processors. Then faster processing will lead to faster designers and an ever-faster design cycle, leading to a limit point soon afterwards. The argument for a speed explosion was set out by the artificial intelligence researcher Ray Solomonoff in his 1985 article “The Time Scale of Artificial Intelligence”.1 Eliezer Yudkowsky gives a succinct version of the argument in his 1996 article “Staring at the Singularity”: “Computing speed doubles every two subjective years of work..

I would like to thank the authors of the 26 contributions to this symposium on my article “The Singularity: A Philosophical Analysis”. I learned a great deal from the reading their commentaries. Some of the commentaries engaged my article in detail, while others developed ideas about the singularity in other directions. In this reply I will concentrate mainly on those in the first group, with occasional comments on those in the second. A singularity (or an intelligence explosion) is a rapid (...) increase in intelligence to superintelligence (intelligence of far greater than human levels), as each generation of intelligent systems creates more intelligent systems in turn. The target article argues that we should take the possibility of a singularity seriously, and argues that there will be superintelligent systems within centuries unless certain specific defeating conditions obtain.

Tim Crane (2011) characterizes the cognitive role of singular thought via singular mental files: the application of such files to more than one object is senseless. As many do, he thus stresses the contrast between ‘singular’ and ‘general’. I give a counterexample, plurally-directed singular thought, and I offer alternative characterizations of singular thought—better described as ‘objects-directed thought’—initially in terms of the defeasibility of the descriptions associated with one's thinking of an object, and then more broadly (...) in terms of whether descriptions of the object or description-independent epistemic routes to the object are primarily operative in an agent's thinking. (shrink)

On the traditional relationalist conception of singular thought, a thought has singular content when it is based on an ‘information relation’ to its object. Recent work rejects relationalism and suggests singular thoughts are distinguished from descriptive thoughts by their inferential role: only thoughts with singular content can be employed in ‘direct’ inferences, or inferences that ‘trade on identity’. Firstly this view is insufficiently clear, because it conflates two distinct ideas—one about a kind of inference, the other (...) a kind of process that grounds inferences—under the title, ‘trading on identity’. Secondly, this leaves us without a notion that can be used as an alternative to relationalism about singular thought. The first notion is no more applicable to singular than to descriptive thought. The second may help us better understand singular thought, but does so, not by replacing the view that singular thoughts are information-based, but by helping us understand the nature of information-based thought.

This essay develops the thesis that Frege’s notion of grasping does not refer to some special psychological relation between a subject and a proposition. Instead, the verb “to grasp” is a contextually defined technical term that, taken by itself, has no meaning. If that is right, then not only Frege’s resentment to the idea of grasping singular propositions is unfounded. The view that intentionality without representations is possible, championed by some advocates of the New Theory of Reference, is groundless (...) as well. (shrink)

A singular thought can be characterized as a thought which is directed at just one object. The term ‘thought’ can apply to episodes of thinking, or to the content of the episode (what is thought). This paper argues that episodes of thinking can be just as singular, in the above sense, when they are directed at things that do not exist as when they are directed at things that do exist. In this sense, then, singular thoughts are (...) not object-dependent. (shrink)

Although the view that sees proper names as referential singular terms is widely considered orthodoxy, there is a growing popularity to the view that proper names are predicates. This is partly because the orthodoxy faces two anomalies that Predicativism can solve: on the one hand, proper names can have multiple bearers. But multiple bearerhood is a problem to the idea that proper names have just one individual as referent. On the other hand, as Burge noted, proper names can have (...) predicative uses. But the view that proper names are singular terms arguably does not have the resources to deal with Burge’s cases. In this paper I argue that the Predicate View of proper names is mistaken. I first argue against the syntactic evidence used to support the view and against the predicativist’s methodology of inferring a semantic account for proper names based on incomplete syntactic data. I also show that Predicativism can neither explain the behaviour of proper names in full generality, nor claim the fundamentality of predicative names. In developing my own view, however, I accept the insight that proper names in some sense express generality. Hence I propose that proper names—albeit fundamentally singular referential terms—express generality in two senses. First, by being used as predicates, since then they are true of many individuals; and second, by being referentially related to many individuals. I respond to the problem of multiple bearerhood by proposing that proper names are polyreferential, and also explain the behaviour of proper names in light of the wider phenomenon I called category change, and show how Polyreferentialism can account for all uses of proper names.

De re or singular thoughts are, intuitively, those essentially or constitutively about a particular object or objects; any thought about different objects would be a different thought. How should a philosophical articulation or thematization of their nature look like? In spite of extended discussion of the issue since it was brought to the attention of the philosophical community in the late fifties by Quine (1956), we are far from having a plausible response. This is glaringly revealed by the contrasting (...) recent takes on the issue by writers such as Soames (2005) – who adopts the view by Donnellan (1979) to be outlined presently – and Jeshion (2001), otherwise sharing a similar direct-reference approach to the prototypical expression of those contents. Discussing the matter in connection with the status of the Kripkean category of the contingent a priori in the just mentioned article, Donnellan (1979) argued that what can be properly classified as knowable a priori about utterances like those involving ‘one meter’ or ‘Neptune’ famously proposed by Kripke (1980) cannot be the very same singular content that is contingent; he distinguished to that end between knowing a true proposition expressed by an utterance, and knowing that an utterance expresses a true proposition. (Thus, for instance, if, while listening to an utterance in a language that I do not know, I am told by a reliable person who knows the language and whom I trust that the utterance is true, I come thereby to know that the sentence expresses a truth, without knowing the truth that it expresses.) Evans (1979) replied that, for a very specific sort of cases involving “descriptive names”, a related proto-two-dimensionalist account should be preferred, on which it is not the singular contingent content, but rather a general descriptive one which is knowable a priori. In a series of papers, Robin Jeshion (2000, 2001) has recently attacked Donnellan's proposal, arguing in favour of the most straightforward interpretation of Kripke's claim: in the relevant cases, the very same singular content can be both contingent and knowable a priori.

What is required for an individual to entertain a singular thought about an object they have encountered before but that is currently no longer within their perceptual range? More specifically, does the individual have to think about the object as having been encountered in the past? I consider this question against the background of the assumption that non-human animals are cognitively ‘stuck in the present’. Does this mean that, for them, ‘out of sight is out of mind’, as, e.g., (...) Schopenhauer seems to have thought? I suggest an alternative answer, also drawing on some empirical work on animal cognition. (shrink)

‘Singular Causes First’ rejects Hume's thesis that singular causal facts are reducible to generic ones, adopting a reverse position, taking singular causes as basic. Using idealized examples, Cartwright shows that strategies to establish causal claims without using singular causal facts as inputs all fail, including probabilistic theories of causality. Not only is singular causal input necessary if probabilities are to imply causal connections, the resulting causal output is also at base singular.

A tacit assumption in the literature devoted to singular thought is that singular thought constitutes a unitary phenomenon, and so a correct account of it must encompass all instances. In this essay, I argue against such a unitary account. The superficial feature of singularity might result from ver y different deep-level phenomena. Following Taylor (2010) and Crane (2013), I distinguish between the referential fitness and the referential success of a thought. I argue that facts responsible for referential fitness (...) (e.g., mental files or individual concepts), as well as facts responsible for referential success (e.g., acquaintance conditions on referential success), are relevant in explaining the data pertaining to a theory of singular thought. What makes this approach particularly attractive is that there are good independent reasons to introduce both kinds of facts in theorizing about thought. (shrink)

This paper is about the Descriptivism/Singularism debate, which has loomed large in 20-century philosophy of language and mind. My aim is to defend Singularism by showing, first, that it is a better and more promising view than even the most sophisticated versions of Descriptivism, and second, that the recent objections to Singularism (based on a dismissal of the acquaintance constraint on singular thought) miss their target.

Postmodernism’s unifying theme of the absent center raises an important question for metaphysics done in the Catholic tradition. Is novelty a “totally other” that utterly eludes human knowing? In posing this question, postmodernism spurs this tradition on to consider afresh how it integrates novelty and contingency. The following study concludes that no adequate account of this integration is possible without a rich concept of the singular. Rahner’s and Balthasar’s metaphysics of the singular shows that contingency, far from being (...) an impasse to a deeper penetration into reality, is the heart of creative process in both human and non-human events. Rahner’s doctrine of substance and Balthasar’s doctrine of analogy deconstruct the relativism in postmodernism’s view of the singular, even as they develop a more extensive view of the singular for which some strains of postmodernism seem instinctively to be groping.

This chapter provides a rich philosophical discussion of superintelligence, a widely discussed piece that has encouraged philosophers of mind to take transhumanism, mind uploading, and the singularity more seriously. It starts with the argument for a singularity: is there good reason to believe that there will be an intelligence explosion? Next, the chapter considers how to negotiate the singularity: if it is possible that there will be a singularity, how can we maximize the chances of a good outcome? Finally, it (...) considers the place of humans in a post‐singularity world, with special attention to questions about uploading: can an uploaded human be conscious, and will uploading preserve personal identity? The chapter also analyzes whether there are certain constraints on design of artificial intelligence (AI) and AI+ that we might impose, in order to increase the chances of a good outcome. (shrink)

The singularity hypothesis is a radical hypothesis about the future of artificial intelligence on which self-improving artificial agents will quickly become orders of magnitude more intelligent than the average human. Despite the ambitiousness of its claims, the singularity hypothesis has been defended at length by leading philosophers and artificial intelligence researchers. In this paper, I argue that the singularity hypothesis rests on scientifically implausible growth assumptions. I show how leading philosophical defenses of the singularity hypothesis (Chalmers 2010, Bostrom 2014) fail (...) to overcome the case for skepticism. I conclude by drawing out philosophical implications of this discussion for our understanding of consciousness, personal identity, digital minds, existential risk, and ethical longtermism.

The aim is to uncover the foundations of quine's distinction between definite singular terms and general terms in predicative position, And hence of the general schema of predication, 'fx'. While each term in such a predication specifies its own item, The items so specified exhibit a typical difference exemplified in the basic case by the difference between spatio-Temporal particulars and properties of such particulars. A generally consequential difference of role is that while both terms are applied to the item (...) of lower type, Only the definite singular term has the function of identifying it. (shrink)

In philosophy, “singular thought” refers to our capacity to represent entities as individuals, rather than as possessors of properties. Philosophers who defend singularism argue that perception allows us to mentally latch onto objects and persons directly, without conceptualizing them as being of a certain sort. Singularists assume that singular thought forms a unified psychological kind, regardless of the nature of the individuals represented. Empirical findings on the special psychological role of persons as opposed to inanimates threaten singularism. They (...) raise the possibility that tracking individuals specifically as persons might require conceptualizing them in certain ways, for example, as persons. In this paper, we take such a possibility seriously but ultimately reject it. Instead, we propose to revise a prominent singularist theory, the theory of mental files, in order to accommodate data on the psychological distinctiveness of persons: We advocate the postulation of perceptual person-files. Perceptual tracking via person-files is different from object-tracking but also from descriptive classification under the sortal concept PERSON. (shrink)

In a recent paper, Armstrong and Stanley argue that despite being initially compelling, a Russellian account of singular thought has deep difficulties. I defend a certain sort of Russellian account of singular thought against their arguments. In the process, I spell out a notion of propositional constituency that is independently motivated and has many attractive features.

Singular terms used in fictions for fictional characters raise well-known philosophical issues, explored in depth in the literature. But philosophers typically assume that names already in use to refer to “moderatesized specimens of dry goods” cause no special problem when occurring in fictions, behaving there as they ordinarily do in straightforward assertions. In this paper I continue a debate with Stacie Friend, arguing against this for the exceptionalist view that names of real entities in fictional discourse don’t work there (...) as they do in simple-sentence assertions, but rather as fictional names do.

In his posthumously published Broken Hegemonies, Reiner Schürmann shows how the ‘tragic denial’ of the differend – between the universal and the singular, natality and mortality, institution and destitution – gives rise to hegemonies. When ‘the sovereign fantasm’ that grounds and anchors the hegemony expires, the hegemony gets withered away. Taking Schürmann’s insights as point of departure, this paper attempts to think of singularisation to come in messianic sense, as truly anarchic thought worthy of our time, that is, to (...) think without hegemonies. Such a messianic/eschatological tragic-anarchic thought can’t be understood as the dialectical operation of the universal’s antagonism to the particular. Beyond the dialectical opposition of the universal and the particular, differend of the singularisation to come can only be understood as the unheard of an-arché, that is, living without ‘why’.

In this paper I challenge the widespread assumption that the conditions for singular reference are more or less the same as the conditions for singular thought. I claim that we refer singularly to things without thinking singularly about them more often than it is usually believed. I first argue that we should take the idea that singular thought is non-descriptive thought very seriously. If we do that, it seems that we cannot be so liberal about what counts (...) as acquaintance; only perception will do. I also briefly discuss and reject semantic instrumentalism. Finally, I argue that while singular reference is cheap, singular thought comes only at a price. (shrink)

It is widely supposed that if there is to be a plausible connection between the truth of a de re attitude report about a subject and that subject’s possession of a singular thought, then ‘acquaintance’-style requirements on singular thought must be rejected. I show that this belief rests on poorly motivated claims about how we talk about the attitudes. I offer a framework for propositional attitude reports which provides both attractive solutions to recalcitrant puzzle cases and the key (...) to preserving acquaintance constraints. The upshot is that there is an independently motivated response to the principal argument against acquaintance. (shrink)

The focus of this paper will be on singular thoughts. In the first section I will present Jeshion’s cognitivism; a view that holds that one should characterize singular thoughts by their cognitive roles. In the second section I will argue that, contrary to Jeshion’s claims, results from studies of object tracking in cognitive psychology do not support cognitivism. In the third section I will discuss Jeshion’s easy transmission of singular thought and argue that it ignores a relevant (...) distinction between general and specific understanding of names. Finally, the last section will argue that conscious attention should replace Jeshion’s significance condition as a necessary condition for one to have a singular thought. The paper will show that we need to take seriously the acquaintance requirement for singular thoughts, as even the easy transmission of singular thoughts with the use of names will be called into question.

This article is a critical notice of Bob Hale and Crispin Wright's *The Reason's Proper Study* (OUP).

In many people, caffeine causes slight muscle tremors, particularly in their hands. In general, the Caffeine → Muscle Tremors causal connection is a noisy one: someone can drink coffee and experience no hand shaking, and there are many other factors that can lead to muscle tremors. Now suppose that Jane drinks several cups of coffee and then notices that her hands are trembling; an obvious question is: did this instance of coffee drinking cause this instance of hand-trembling? Structurally similar questions (...) arise throughout everyday life: Did this pressing of the ‘k’ key cause this change in the pixels on the computer monitor? Did these episodes of smoking cause this lung cancer? Did this studying cause this test score? And so on. These questions all ask about singular causation in a particular situation, in contrast with general causation across multiple cases. They are thus particularly salient in situations in which we care about that specific case, as in many legal contexts, social interactions, physical explanations of anomalous events, and more.

Although we are still in the dark when it comes to giving necessary and jointly sufficient criteria for what it takes to be thinking a singular thought, the paradigm cases are just ones where an agent is thinking about some particular object. When we erroneously think that Vulcan is a planet, our thought appears to be singular since it is, after all, about Vulcan. A promising way to explain this is to claim that there is something, a merely (...) hypothetical entity, that is Vulcan. There have been notable supporters for positing hypothetical entities for some time now, but the account of how we create hypothetical entities is still underdeveloped. In fact, we face a puzzle if we assume: hypothetical entities are created by us; we create a given hypothetical entity only when we falsely hypothesize something to be the unique F; we create the hypothetical entity long before we learn that there is no unique F. How can we possibly manage to conditionally and unknowingly create some entity when there is no unique F? In showing how this is possible, it will become clear that we have good reason for preferring a view that posits hypothetical entities over the alternative ways of accounting for our apparently singular thoughts about Vulcan, Pegasus, the Fountain of Youth, and so on.

Their contributions go beyond speculation, providing deep insights into the main issues and a balanced picture of the debate. (shrink)

Ray Kurzweil and others have posited that the confluence of nanotechnology, artificial intelligence, robotics, and genetic engineering will soon produce posthuman beings that will far surpass us in power and intelligence. Just as black holes constitute a ldquo;singularityrdquo; from which no information can escape, posthumans will constitute a ldquo;singularity:rdquo; whose aims and capacities lie beyond our ken. I argue that technological posthumanists, whether wittingly or unwittingly, draw upon the long-standing Christian discourse of ldquo;theosis,rdquo; according to which humans are capable of (...) being God or god-like. From St. Paul and Luther to Hegel and Kurzweil, the idea of human self-deification plays a prominent role. Hegel in particular emphasizes that God becomes wholly actualized only in the process by which humanity achieves absolute consciousness. Kurzweil agrees that God becomes fully actual only through historical processes that illuminate and thus transform the entire universe. The difference is that for Kurzweil and many other posthumanists, our offspringmdash;the posthumansmdash;will carry out this extraordinary process. What will happen to Home sapiens in the meantime is a daunting question. (shrink)

What is a singular object? An idea, a building, a color, a sentiment, a human being. Each in turn comes under scrutiny in this exhilarating dialogue between two of the most interesting thinkers working in philosophy and architecture today. From such singular objects, Jean Baudrillard and Jean Nouvel move on to fundamental problems of politics, identity, and aesthetics as their exchange becomes an imaginative exploration of the possibilities of modern architecture and the future of modern life. Among the (...) topics the two speakers take up are the city of tomorrow and the ideal of transparency, the gentrification of New York City and Frank Gehry’s surprising Guggenheim Museum in Bilbao. As Nouvel prompts Baudrillard to reflect on some of his signature concepts, the confrontation between such philosophical concerns and the specificity of architecture gives rise to novel and striking formulations—and a new way of establishing and understanding the connections between the practitioner and the philosopher, the object and the idea. This wide-ranging conversation builds a bridge between the fields of architecture and philosophy. At the same time it offers readers an intimate view of the meeting of objects and ideas in which the imagined, constructed, and inhabited environment is endlessly changing, forever evolving. Jean Baudrillard is one of the most influential thinkers of his generation and author of _The Vital Illusion_. Jean Nouvel has designed buildings throughout the world, including the new Guthrie Theater in Minneapolis, and is a recipient of France’s Grand Prix d’Architecture. Robert Bononno, a translator and teacher, lives in New York City. (shrink)

Kant's distinction between intuitive and discursive knowledge precludes his giving intuitions linguistic representation. Singular terms represent concepts given what kant calls a 'singular use' and are analyzable as definite descriptions. That the object described exists and that there is only one such object can be given linguistic representation only through an explicit assertion of existence and uniqueness. As an intuitionist in mathematics kant holds that mathematics proclaims the constructibility and not the existence of its objects.

Neo-Fregeans take their argument for arithmetical realism to depend on the availability of certain, so-called broadly syntactic tests for whether a given expression functions as a singular term. The broadly syntactic tests proposed in the neo-Fregean tradition are the so-called inferential test and the Aristotelian test. If these tests are to subserve the neo-Fregean argument, they must be at least adequate, in the sense of correctly classifying paradigm cases of singular terms and non-singular terms. In this paper, (...) I pursue two main goals. On the one hand, I show that the tests’ current state-of-the-art formulations are inadequate and, hence, cannot subserve the neo-Fregean argument. On the other hand, I propose revisions that are adequate and, hence, can subserve this argument. (shrink)

According to many actualists, propositions, singular propositions in particular, are structurally complex, that is, roughly, (i) they have, in some sense, an internal structure that corresponds rather directly to the syntactic structure of the sentences that express them, and (ii) the metaphysical components, or constituents, of that structure are the semantic values — the meanings — of the corresponding syntactic components of those sentences. Given that reference is "direct", i.e., that the meaning of a name is its denotation, an (...) apparent consequence of this view is that any proposition expressed by a sentence containing a name that denotes a contingent being S is itself contingent — notably, the proposition [S does not exist]. Assuming that an entity must exist to have a property, necessarily, [S does not exist] must exist in order to be true. It seems to follow that, necessarily, [S does not exist] is not true and, hence, that S is not contingent after all. Past approaches to the problem — notably, those of Prior and Adams — lead to highly undesirable consequences for quantified modal logic. In this paper, several solutions to this puzzle are developed that preserve actualism, the structured view of propositions, the direct theory of reference, and the intuition that [S does not exist] is indeed possible without the adverse consequences for QML of previous solutions.

In a series of papers, Robin Jeshion has forcefully criticized both Donnellan's and Evans’ claims on the contingent a priori, and she has developed an “acquaintanceless” account of singular thoughts as an alternative view. Jeshion claims that one can fully grasp a singular thought expressed by a sentence including a proper name, even if its reference has been descriptively fixed and one’s access to the referent is “mediated” by that description. But she still wants to reject “semantic instrumentalism”, (...) the view that “there are no substantive conditions of any sort on having singular thought. We can freely generate singular thoughts at will by manipulating the apparatus of direct reference.” Her account of singular thoughts is a psychological one, rejecting any epistemic requirement. Having singular thoughts is for her a matter of deploying “mental files” or “dossiers” that play a significant role in the cognitive life of the individual. This paper elaborates on an alternative descriptivist-friendly view, which has important points of contact with Jeshion’s. It differs, particularly in that it is an epistemic view; it is only a broadly understood acquaintance view, as it will transpire, but this does not make it a mere terminological variation on Jeshion’s acquaintanceless one. To argue for it, the paper discusses some relevant aspects of the semantics of fictional discourse. (shrink)

This paper contains two traditions of diagrammatic studies namely one, the Euler–Venn–Peirce diagram and the other, following tradition of Aristotle, the square of oppositions. We put together both the traditions to study representations of singular propositions, their negations and the inter relationship between the two. Along with classical negation we have incorporated negation of another kind viz. absence. We have also considered the changes that take place in the context of open universe.

Singularities in general relativity and quantum field theory are often taken not only to motivate the search for a more-fundamental theory (quantum gravity, QG), but also to characterise this new theory and shape expectations of what it is to achieve. Here, we first evaluate how particular types of singularities may suggest an incompleteness of current theories. We then classify four different 'attitudes' towards singularities in the search for QG, and show, through examples in the physics literature, that these lead to (...) different scenarios for the new theory. Two of the attitudes prompt singularity resolution, but only one suggests the need for a theory of QG. Rather than evaluate the different attitudes, we close with some suggestions of factors that influence the choice between them. (shrink)

This paper deals with the mutations in Wittgenstein’s treatment of the notions of “generality” and of “singularity”, from his first philosophy, in the Tractatus Logico-Philosophicus, to his later mature philosophy represented by the Philosophical Investigations. As we shall see, Wittgenstein’s philosophical handling of the notion of “visual perception” plays a key role in those conceptual transformations.
