Commitment to sparseness amounts to the idea that there is an objective, worldly privileging of certain properties over others that makes the privileged properties suited to play certain roles, and is responsible for their playing such roles. In this chapter I offer a brief, opinionated overview of sparseness. I begin by examining a set of problems that I call “problems of abundance”, which generate canonical motivations for sparseness. I then survey some influential approaches to sparseness and (...) the roles that they attribute to sparse properties, noting that on most approaches sparse properties are deeply connected to inquiry. Finally I consider some problems for sparseness, focusing on the purported connections between sparseness and inquiry, particularly in philosophy of science and inquiry into the social world.

In the past fifteen years or so there has been a lot of attention paid to theories of “sparse” universals, particularly because of the work of D. M. Armstrong. These theories are of particular interest to those of us concerned with the distinction between natural and non-natural properties, since, as David Lewis has observed, it seems possible to analyze naturalness in terms of sparse universals. Moreover, Armstrong claims that we should conceive of universals as being “immanent” as opposed to “transcendent”, (...) and if universals are immanent then, as we will see, there is pressure to admit they are sparse as well. But I will argue that neither of these alleged reasons to accept a sparse conception of universals succeeds: the outlook for a fully general analysis of naturalness in terms of universals is not good, and the apparent advantages of immanence over transcendence are illusory.

Answers are given to two questions concerning the existence of some sparse subsets of $\mathscr{H} = \{0, 1,..., H - 1\} \subseteq * \mathbb{N}$ , where H is a hyperfinite integer. In § 1, we answer a question of Kanovei by showing that for a given cut U in H, there exists a countably determined set $X \subseteq \mathscr{H}$ which contains exactly one element in each U-monad, if and only if U = a · N for some $a \in \mathscr{H} (...) \backslash \{0\}$ . In §2, we deal with a question of Keisler and Leth in [6]. We show that there is a cut $V \subseteq \mathscr{H}$ such that for any cut U, (i) there exists a U-discrete set $X \subseteq \mathscr{H}$ with X + X = H (mod H) provided $U \subsetneqq V$ , (ii) there does not exist any U-discrete set $X \subseteq \mathscr{H}$ with X + X = H (mod H) provided $\supsetneqq V$ . We obtain some partial results for the case U = V. (shrink)

Are the sparse properties drawn from all the levels of nature, or only the fundamental level? I discuss the notion of sparse property found in Armstrong and Lewis, show that there are tensions in the roles they have assigned the sparse properties, and argue that the sparse properties should be drawn from all the levels of nature.

Sparse languages play an important role in classical structural complexity theory. In this paper we introduce a natural definition of sparse problems for parameterized complexity theory. We prove an analog of Mahaney's theorem: there is no sparse parameterized problem which is hard for the tth level of the W hierarchy, unless the W hierarchy itself collapses up to level t. The main result is proved for the most general form of parametric many:1 reducibility, where the parameter functions are not assumed (...) to be recursive. This provides one of the few instances in parameterized complexity theory of a full analog of a major classical theorem. The proof involves not only the standard technique of left sets, but also substantial circuit combinatorics to deal with the problem of small weft, and a diagonalization to cope with potentially nonrecursive parameter functions. The latter techniques are potentially of interest for further explorations of parameterized complexity analogs of classical structural results. (shrink)

Four dimensionalism, the thesis that persisting objects are four dimensional and thus extended in time as well as space, has become a serious contender as an account of persistence. While many four dimensionalists are mereological universalists, there are those who find mereological universalism both counterintuitive and ontologically profligate. It would be nice then, if there was a coherent and plausible version of four dimensionalism that was non-universalist in nature. I argue that unfortunately there is not. By its very nature four (...) dimensionalism embraces theses about the nature of objects and their borders that make any version of non-universalist four dimensionalism either incoherent or at least highly implausible.

Zombies are bodies without minds: creatures that are physically identical to actual human beings, but which have no conscious experience. Much of the consciousness literature focuses on considering how threatening philosophical reflection on such creatures is to physicalism. There is not much attention given to the converse possibility, the possibility of minds without bodies, that is, creatures who are conscious but whose nature is exhausted by their being conscious. We can call such a ‘purely conscious’ creature a ghost.

David Lewis is typically interpreted as a class nominalist. One consequence of class nominalism, which he embraced, is that the reduction of ordered pairs, triples, etc to unordered sets of sets is conventional. The reaction by his Australian counterparts D.M. Armstrong and Peter Forrest was that Lewis was not being ontologically serious. This chapter evaluates this debate over serious ontology. It is argued that in one sense Lewis is ontologically serious, but that his additional commitment to structuralism about classes should (...) push him to adopt a trope-theoretic account of naturalness, which opens up another way to respond to the charge of not doing serious ontology. This conclusion is supported by certain remarks he makes in his correspondence, thus revealing how his thinking about properties appears to have evolved from property-egalitarianism to a sparse theory of tropes.

According to sparse modalism, the notion of essence can be analysed in terms of necessity and naturalness. In this paper, I develop and defend a version of sparse modalism that is equipped with a non-standard, relativized conception of naturalness. According to this conception, properties and relations can be natural to different degrees relative to different kinds of things, and relations can be natural to different degrees relative to different slots. I argue that this relativized version of sparse modalism can accommodate (...) various cases that the standard, non-relativized version can’t. The alternative version can accommodate cases where a relation is essential to a relatum but merely necessary to another, cases where a property is essential to an object but merely necessary to another, and cases where a less-than-perfectly natural property is essential to an object.

Natural kind terms appear to behave like singular terms. If they were genuine singular terms, appearing in true sentences, that would be some reason to believe that there are entities to which the terms refer, the natural kinds. Paul Needham has attacked my arguments that natural kind terms are singular, referring expressions. While conceding the correctness of some of his criticisms, I defend and expand on the underlying view in this paper. I also briefly sketch an account of what natural (...) kinds in fact are—natural complexes of sparse (natural) universals. (shrink)

Dispositional essentialism maintains that all sparse properties are essentially powerful. Two conceptions of sparse properties appear compatible with dispositional essentialism: sparse properties as pure powers or as powerful qualities. This paper compares the two views, criticizes the powerful qualities view, and then develops a new theory of pure powers, termed Point Theory. This theory neutralizes the main advantage powerful qualities appear to possess over pure powers—explaining the existence of powers during latency periods. The paper discusses the relation between powers and (...) space-time points, whether pure powers need to occupy space, and how to account for the movement of pure powers through space-time. Given Point Theory, dispositional essentialists should maintain that sparse properties are pure powers. (shrink)

This article analyses the different connotations of “normality” and “being natural,” bringing together the theoretical discussion from both human medicine and veterinary medicine. We show how the interpretations of the concepts in the different areas could be mutually fruitful. It appears that the conceptions of “natural” are more elaborate in veterinary medicine, and can be of value to human medicine. In particular they can nuance and correct conceptions of nature in human medicine that may be too idealistic. Correspondingly, the wide (...) ranging conceptions of “normal” in human medicine may enrich conceptions in veterinary medicine, where the discussions seem to be sparse. We do not argue that conceptions from veterinary medicine should be used in human medicine and vice versa, but only that it could be done and that it may well be fruitful. Moreover, there are overlaps between some notions of normal and natural, and further conceptual analysis on this overlap is needed. (shrink)

A fundamental question in visual neuroscience is: Why are the response properties of visual neurons as they are? A modern approach to this problem emphasizes the importance of adaptation to ecologically valid input, and it proceeds by modeling statistical regularities in ecologically valid visual input (natural images). A seminal model was linear sparse coding, which is equivalent to independent component analysis (ICA), and provided a very good description of the receptive fields of simple cells. Further models based on modeling residual (...) dependencies of the ‘‘independent” components have later been introduced. These models lead to emergence of further properties of visual neurons: the complex cell receptive fields, the spatial organization of the cells, and some surround suppression and Gestalt effects. So far, these models have concentrated on the response properties of neurons, but they hold great potential to model various forms of inference and learning. (shrink)

Many human languages have complex grammatical machinery devoted to temporality, but very little is known about how this came about. This paper investigates how people convey temporal information when they cannot use any conventional languages they know. In a laboratory experiment, adult participants were asked to convey information about simple events taking place at a given time, in spoken language and in silent gesture. It was shown that in spoken language, participants formed utterances according to the rules of their native (...) language, but in silent gesture, the temporal information was presented initially, and structurally separately, from the other information in the utterance. The experimental results are consistent with findings from natural systems emerging in situations of communicative stress: unsupervised adult second language learning and homesign. This confirms that presenting temporal information separately and initially is a robust strategy to talk about past and future when only sparse communicative means are available. (shrink)

Among those who posit properties, liberals (mostly nominalists) admit abundant, ontologically free properties, which particulars possess whenever they satisfy the same predicate and belong to the same class, however artificial. I call them “L-properties” (for “Liberal”). Some liberals also admit that some few L-properties are natural, while most of them are artificial (the same applies to the corresponding classes). Others (mostly but not only realists) commit to a more discriminating use of the category: properties are sparse, they make for the (...) objective similarities among particulars, and more importantly, they allow to analyze “objective similarity” and “class naturalness” in terms of property-possessing and sharing. They give particulars their “true nature”, and I call them “A-properties” (for “Analytical”). This article provides a defense of this second type of properties, in the particular case of sortals. To that end, a new fact is put forward: that sorts are classes which are natural not as a primitive feature, but in virtue of what the particulars which belong to them are, and which makes them _naturally belong_ to them. I then argue that this fact entails the existence of the desired type of properties, “sortal A-properties”, although leaving open the question of how they should be construed. (shrink)

The conduct of hostilities is very bad for the environment, yet relatively little attention has been focused on environmental military ethics by just war theorists and revisionist philosophers of war. Contemporary ecological concerns pose significant challenges to jus in bello. I begin by briefly surveying existing literature on environmental justice during wartime. While these jus in bello environmental issues have been addressed only sparsely by just war theorists, environmental jus ad bellum has rarely been tackled within JWT or the morality (...) of war. In line with the theme of this special issue, I focus my discussion of war and the natural environment primarily on the jus ad bellum level. I set out with the presumption against the use of force, and its possible exceptions. The principal question raised is whether environmental harm can trigger a new justification for war. Beyond just cause, I consider what might be a proportionate response to “environmental aggression,” or negligent harm to nature. The use of force is clearly justified in response to military attacks, against the natural environment or otherwise. Where harm to nature or its inhabitants are not caused by military aggression, just war theory criteria point in favor of responding via measures short of war. Finally, I suggest that responding by means that are not themselves harmful to nature serves to fulfill the further jus ad bellum criterion of “right intention.”. (shrink)

For all of his failures to secure patronage, John Dee was successful compared with his contemporaries. We know more about his patronage relations than those of any other natural philosopher in Tudor England. Only by comparing him with other English client practitioners can we understand how unusual and even productive were Dee’s relations with his patrons. This article makes those comparisons and offers an overview of Dee’s patronage, but in the main it explores three of the unusual aspects.The first is (...) Dee’s good relationship with female patrons and patronage brokers, notably Queen Elizabeth. The second is the kind of office that Dee sought. His greatest efforts were aimed at securing the headship of a collegiate institution such as Eton College or the Hospital of St Cross. Not only did they fit his aspiration to set up a research institute, but all were offices in the Queen’s direct gift, and so played to Dee’s strengths. Nevertheless, Dee was frustrated at nearly every turn. It is suggested that a major cause was the young Dee’s links with both Sir John Cheke’s network of Protestant humanists, who became Marian exiles, and with ‘Louvainist’ Catholic exiles opposed to Edward VI and Elizabeth. We see how Dee was consistently passed over in favour of other members of these circles. Notwithstanding this, it is concluded that Dee was relatively successful, given the English court’s refusal to patronise speculative natural philosophy, even that offered by Thomas Digges, William Gilbert or Francis Bacon. Finally, some of Dee’s supposed failings as a client, such as the sparseness of printed works, are shown to have been systemic. (shrink)

The authors explicate Aquinas's conception of mathematics. They show that in his work the Aristotelian conception is prevalent, according to which this discipline is—together with physics and metaphysics—a theoretical science, whose subject is the study of real quantity and its necessary properties. But, alongside this dominant and prevalent conception, Aquinas's work contains a number of indications that cast doubt. These sparse and rather marginal reflections lead the authors to conclude that Aquinas's texts contain a "constructivist" conception of mathematics in rudimentary (...) form. According to this approach, mathematics is not a theoretical science examining real quantity but, rather, a special kind of "art" by means of which mathematical objects are "created." From a constructivist point of view the authors then attempt to formulate a conception of mathematics that would accord with the basic Aristotelian assumptions of Aquinas's thought. (shrink)

I argue that there is no metaphysically substantive property of truth. Although many take this thesis to be central to deflationism about truth, it is sometimes left unclear what a metaphysically substantive property of truth is supposed to be. I offer a precise account by relying on the distinction between the property and concept of truth. Metaphysical substantivism is the view that the property of truth is a sparse property, regardless of how one understands the nature of sparse properties. I (...) then offer two new arguments against metaphysical substantivism that employ ideas involving recombination and truthmaking. First, I argue that there are no theoretically compelling reasons to posit the existence of a metaphysically substantive property of truth. Secondly, I argue that if we do posit the existence of such a property, then we end up with a view that is either contradictory or unmotivated. What we’re left with is a metaphysically deflationary account of the property of truth that fully respects the metaphysical ambitions of truthmaker theory, and that is consistent with both the view that truth is a deflated, explanatorily impotent concept and the view that truth is an explanatorily powerful concept.

This chapter is an edited transcription of an author-meets-critics session at the Truth 20|20 Conference, on Douglas Edwards’ award-winning book, The Metaphysics of Truth (2018, Oxford University Press). The Metaphysics of Truth tackles fundamental questions about the role of truth in connections between language and the world. Edwards proposes a pluralist account, according to which sentences in different domains get to be true in different ways. Kellen’s questions center around how to locate Edwards’s pluralist account given certain distinctions between varieties (...) of truth pluralism, and on how to determine what domains certain sentences belong to, especially mixed compounds. Taylor’s comments critically investigate Edwards’ critiques of deflationism, particularly to do with what the deflationist can say about whether truth counts as a ‘sparse’ or ‘abundant’ property, and whether deflationists are able to explain important differences between sparse properties such as being magnetic, and abundant properties, which deflationists will likely think include being true. Lynch provides several questions about the metaphysics of Edwards’s account, including the nature of the determination relation, and the nature of the property of truth itself, and whether Edwards’s account of that property manages to distinguish itself from something a truth minimalist would be happy with.

In the natural and social sciences, it is common to use toy models—extremely simple and highly idealized representations—to understand complex phenomena. Some of the simple surrogate models used to understand opaque machine learning (ML) models, such as rule lists and sparse decision trees, bear some resemblance to scientific toy models. They allow non-experts to understand how an opaque ML model works globally via a much simpler model that highlights the most relevant features of the input space and their effect on (...) the output. The obvious difference is that the common target of a toy and a full-scale model in the sciences is some phenomenon in the world, while the target of a surrogate model is another model. This essential difference makes toy surrogate models (TSMs) a new object of study for theories of understanding, one that is not easily accommodated under current analyses. This paper provides an account of what it means to understand an opaque ML model globally with the aid of such simple models. (shrink)

This paper presents an account of what it is for a property or relation (or ‘attribute’ for short) to be logically simple. Based on this account, it is shown, among other things, that the logically simple attributes are in at least one important way sparse. This in turn lends support to the view that the concept of a logically simple attribute can be regarded as a promising substitute for Lewis’s concept of a perfectly natural attribute. At least in part, the (...) advantage of using the former concept lies in the fact that it is amenable to analysis, where that analysis—i.e., the account put forward in this paper—requires the adoption neither of an Armstrongian theory of universals nor of a primitive notion of naturalness, fundamentality, or grounding.

Metaphysicians often distinguish between joints and basic ways. Joints are the unified and joint-carving properties that trace the structure of the world. They are theorized under the ideology of structural, perfectly natural, or sparse properties. Basic ways are the ultimate and independent properties that give rise to all others. They are theorized under the ideology of grounding, where the ungrounded properties are the basic ways. While these notions are often seen as rivals, I argue that we need both, because the (...) joints and the basic ways crosscut. For the sake being exhaustive and ecumenical, I distinguish between natural and normative sorts of joints and basic ways. I argue that, for either sort, if there is such a sort of joint and basic way, then there are joints that are not basic ways and there are basic ways that are not joints. (shrink)

According to Sparse views of perceptual content, the phenomenal character of perceptual experience is exhausted by the experiential presentation of ‘low-level’ properties such as (in the case of vision) shapes, colors, and textures Whereas, according to Rich views of perceptual content, the phenomenal character of perceptual experience can also sometimes involve experiencing ‘high-level’ properties such as natural kinds, artefactual kinds, causal relations, linguistic meanings, and moral properties. An important dialectical tool in the debate between Rich and Sparse theorists is the (...) so-called ‘method of phenomenal contrast’. I explore how this method of phenomenal contrast interacts with the sort of content-externalism made familiar by Putnam. I show that the possibility of Twin Earth style cases places important restrictions on the range of properties that the method of phenomenal contrast could plausibly apply to. Moreover, these restrictions would apply to some paradigmatically low-level properties as well as to some of the frequently advanced high-level properties. I also draw some general lessons about the different ways one might conceive of the relation between phenomenal character and representational content. (shrink)

Essentialists hold that at least a certain range of entities can be meaningfully said to have natures, essences, or essential features independently of how these entities are described, conceptualized or otherwise placed with respect to our specifically human interests, purposes or activities. Modalists about essence, on the one hand, take the position that the essential truths are a subset of the necessary truths and the essential properties of entities are included among their necessary properties. Non-modalists about essence, on the other (...) hand, oppose the reduction of essence to modality and hold, rather, that essence is more basic than, and explanatory of, modality. This chapter begins with a brief summary of Kit Fine’s well-known challenges to the modal account of essence and considers a recent attempt by “sparse modalists” like Sam Cowling and Nathan Wildman to respond to Fine’s counterexamples by adding a sparseness constraint to the “bare” modal account of essence. A further question arises, however, as to whether and how Fine’s definitional approach can avoid his own counterexamples against the modal approach to essence. The chapter concludes with some final thoughts concerning the theoretical roles ascribed to essence by modalists and non-modalists. (shrink)

It is widely agreed among philosophers of science today that no formal pattern can possibly be found in the origins of scientific theory. There is no such thing as a "logic of discovery," insists this view--a scientific hypothesis is susceptible to methodological critique only in its relation to empirical consequences derived after the hypothesis itself has emerged through a spontaneous creative inspiration. Yet confronted with the tautly directed thrust of theory-building as actually practiced at the cutting edge of scientific research, (...) this romantic denial of method in the genesis of ideas takes on the appearance of myth. It is the contention of this article that as empirical data ramify in logical complexity, they deposit a hard sediment of theory according to a standard inductive pattern so primitively compelling that it must be recognized as one of the primary forms of inferential thought. This process, here called "ontological induction," is a distillation out of unwieldly observed regularities of more conceptually tractable states hypothesized to underlie them, and is the wellspring of our beliefs in theoretical entities. Previous failure to recognize this pattern of induction has undoubtedly been in substantial measure a result of inadequate attention to the structural details of scientific propositions; for in order to exhibit the nature of ontological induction clearly, it is first necessary to make extended forays through sparsely explored methodological terrain--notably, the nature of scientific "variables," the logical form of "laws," and the type-hierarchy of scientific concepts.

What determines qualitative sameness and difference? This book explores four principal accounts of the ontological basis of properties, including universals, trope theory, resemblance nominalism, and class nominalism, considering the assumptions and ontolological commitments which are required to make each into a plausible account of properties. -/- The latter half of the book investigates the applications of property theory and the different conceptions of properties which might be adopted with these in mind: first, the possibility and desirability of individuating properties, and (...) the distinction between sparse and abundant conceptions of properties; second, the distinction between intrinsic and extrinsic properties; third, the relationship between properties and their causal powers, and whether this is necessary or contingent; fourth, the relationship between properties and causation, modality, and laws of nature; finally, whether properties exist objectively, and if they do, what our epistemic position is with respect to such entities.

Page's “localist” code, a population code with occasional, maximally firing elements, does not seem to us usefully or testably different from sparse population coding. Some of the evidence adduced by Page for his proposal is not actually evidence for it, and coding by maximal firing is challenged by lower firing observed in neuronal responses to natural stimuli.

It seems to be a fact about language that people carry on competent and intelligent conversations, day to day, without being able to explain the words they're using. People don't have definitions, even tacit ones, for their words. This is possible in part because language users live in a social network, relying on one another as well as the structure of the world, which takes the burden of definition off the shoulders of the ordinary language user. ;Still, even simple words (...) in fact stand for extremely complex and not especially natural kinds of things. In many cases, it's unlikely that we can look to the traditional sources---either to the definitions of even the most informed experts, or to the regular structures in nature and human practices---for endowing words with meaning. In this dissertation, I work at the margins of the theory of reference, to develop an account of the factors that make it possible for us to introduce words into language. Social kinds are paradigmatic instances of the phenomenon of establishing reference. ;I argue that establishing reference imposes less of a cognitive burden on language users than classic and contemporary accounts suppose. In particular, we often introduce words into language without even having the ability to identify what factors are involved in settling their reference. The reason is that the world---even the world of candidate social kinds---is a sparse place. A rich set of distributed conceptual factors figure into setting up the candidates for reference and hence for settling the reference of newly introducing words, even when the person fixing reference doesn't invoke these factors. I consider the factors that make the world sparse, in particular focusing on both conceptual and historical factors. Moreover, I suggest that studying reference to social kinds doesn't only shed light on how reference fixing works and on the nature of social kinds, but also can be applied reciprocally to reference, understanding language and reference themselves to be social kinds.

Five aspects of visual change detection are reviewed. The first concerns the concept of change itself, in particular the ways it differs from the related notions of motion and difference. The second involves the various methodological approaches that have been developed to study change detection; it is shown that under a variety of conditions observers are often unable to see large changes directly in their field of view. Next, it is argued that this “change blindness” indicates that focused attention is (...) needed to detect change, and that this can help map out the nature of visual attention. The fourth aspect concerns how these results affect our understanding of visual perception—for example, the implication that a sparse, dynamic representation underlies much of our visual experience. Finally, a brief discussion is presented concerning the limits to our current understanding of change detection. (shrink)

It is widely agreed that play and games contribute to the good life. One might naturally wonder how games in particular so contribute? Granted, games can be very good, what exactly is so good about them when they are good? Although a natural starting point, this question is perhaps naive. Games come in all shapes and sizes, and different games are often good in very different ways. Chess, Bridge, Bingo, Chutes and Ladders, Football, Spin the Bottle, Dungeons & Dragons, Pac-Man, (...) Minecraft and Charades are all games, and can all contribute to a good life, but each will characteristically enrich someone’s life in its own distinctive way. Some games facilitate socializing and sociability, other games improve physical fitness, some develop a sense of fair play and reciprocity, while others enhance concentration and analytic skills. Asking ‘what is good about games?’ and assuming a simple answer is as naïve as asking ‘what is good about fiction?’ or ‘what is good about sex?’ However, a less naïve question and philosophically interesting question is not hard to formulate. Plausibly, much of the heterogeneity of the value of games stems from the different kinds of instrumental value of different games. Perhaps we should therefore ask in what ways the activity of playing games is characteristically good for its own sake. Unfortunately, the philosophical literature on the non-instrumental value of playing games is sparse. One of the few sustained treatments of the topic can be found in an underappreciated exchange between Thomas Hurka and John Tasioulas. Interestingly, despite taking different views of what it is to play a game, they both make room for the non-instrumental value of play and achievement in game play and they both argue that these two goods stand in important an important explanatory relation. However, they take diametrically opposed views as to which of these good is more basic. Roughly, on Hurka’s view, the good of achievement is more basic, and it is because of the non-instrumental value of achievement that what Hurka calls “playing in a game,” which involves playing, is itself non-instrumentally good because of the non-instrumental value of achievement. The idea is that if something is non-instrumentally good then loving that thing is also non-instrumentally good, and that playing in a game involves loving the activity for its own sake. In this way, the value of achievement in a game grounds the value of playing in a game. Tasioulas takes exactly the opposite approach. He argues that there must be something independently good about playing a game which grounds the value of achievement in that game. On his view, the typical grounding good or “framing value” of games is play itself – what I am here calling “playing.” In this essay, I raise some objections to both Hurka’s view and Tasioulas’s view and develop a positive alternative conception of the non-instrumental value of games. I argue that while each view is insightful in its own way, neither gets things exactly right. For a start, the way in which they characterize the key concepts is problematic. Hurka’s definition of ‘play a game’, which he lifts from Suits, is problematic, while both of their characterizations of play are problematic for reasons I rehearse here. They also take an unduly narrow view of the possible role of achievement in game play, both effectively conflating achievement with “excellence.” I argue, by contrast, that there is an important sense in which even someone who is not very good at the game by any objective standard can still reap the goods of achievements in games. At the same time, those who play games typically do not do so for the sake of achievements as such, though they may do something which is in a sense tantamount to this, or so I shall argue. Finally, I argue that neither Hurka’s “achievement first” order of explanation nor Tasioulas’s “play first” order of explanation is fully correct. I argue for what I call a “variable priority” view. On this view, the value of play sometimes grounds the value of achievement in a game, while in other cases the independently grounded value of achievement in a game provides a further ground for the value of play, though even in that case play is independently good for its own sake. I begin by laying out Hurka’s and Tasioulas’s views. (shrink)

This chapter takes as its point of departure the frequent injunction in Beckett’s late prose works to build or construct an environment for a character to inhabit. It is proposed that this instruction is central to the textual operations of the late prose. Making use of the work of Philippe Hamon on text and architecture, and through a close reading of Beckett’s short prose piece (originally written as a libretto for Morton Feldman), it is argued that, despite its sparse nature, (...) ‘Neither’ can, in large part, still be read as exemplifying Hamon’s insights into the operations of the textual and the architectural as these were manifest in the classic realist novel. The specific challenges which Beckett’s late prose present, however, require a supplementary critical vocabulary in order to account for the manner in which the textual and the architectural interpenetrate and expose each other in the twentieth century.

Set in the minimalist abode of a sparsely furnished hotel room, Awaiting Oblivion narrates the encounter between a man and a woman, anonymously known as Il and Elle, respectively. The plot revolves around their relationship, the nature of which is the concern of their dialogue. Their dialogue intermittently emerges through a narrative voice that is, however, infused with the very same confusion and vacillation as is their own speech. The man and woman are caught in an undulating relation of attraction (...) and repulsion, as they endeavour to rediscover the desire they once felt for one another. The themes of waiting and forgetting are manifested within the plot in their vain efforts to remember a past event whilst, paradoxically, simultaneously awaiting the event’s recurrence. This event constitutes their first encounter, the memory of which will affect their future relationship. However, each person has his own perception of how this initial encounter had transpired, the memory of which is constantly being revised, over time. The couple engage in lengthy conversations in their attempts to overcome this discrepancy. First, Il expresses his perception of the event. Sensing problematic elements in his account, Elle recounts her version of how things had transpired, while Il attempts accurately to transcribe her words. With time, Il and Elle are able to arrive at a mutually balanced view of the event. Ironically, it is through waiting and forgetting that they are able to arrive at this point. (shrink)

Reason has reasons of which ‘reason’ knows nothing. It was this essential insight, along with the methodological prioritisation of a phenomenology of cognition and the recognition of the epistemological distinctiveness of judgment, that a young Bernard Lonergan gleaned from his study of John Henry Newman's Grammar of Assent. Given that the ‘later’, post‐Insight (1953) Lonergan enacted a more explicit transposition of his thought into a hermeneutical and existential framework, one might be tempted to assume that this coincided with a drift (...) away from his tutelage under the nineteenth‐century Englishman. Indeed, an examination of the secondary literature detailing their relationship would suggest as much. Yet, in the hope of contributing to the regrettably sparse Newman‐Lonergan scholarship and proposing a modest recalibration therein, I argue that the more existential, hermeneutical, and committed to the philosophical turn to concrete socio‐historical subjectivity Lonergan grew, the more fruit his early Newmanian formation bore. By analysing Newman's proto‐Lonerganian anticipations in the areas of self‐appropriation, conversion, the relationship of subjectivity to objectivity, and the hermeneutical nature of consciousness, I will contend that Newman—a presciently continental mind writing as one untimely born into an analytical milieu—was the wellspring from which Lonergan never ceased to draw.

I defend a one category ontology: an ontology that denies that we need more than one fundamental category to support the ontological structure of the world. Categorical fundamentality is understood in terms of the metaphysically prior, as that in which everything else in the world consists. One category ontologies are deeply appealing, because their ontological simplicity gives them an unmatched elegance and spareness. I’m a fan of a one category ontology that collapses the distinction between particular and property, replacing it (...) with a single fundamental category of intrinsic characters or qualities. We may describe the qualities as qualitative charactersor as modes, perhaps on the model of Aristotelian qualitative (nonsubstantial) kinds, and I will use the term “properties” interchangeably with “qualities”. The qualities are repeatable and reasonably sparse, although, as I discuss in section 2.6, there are empirical reasons that may suggest, depending on one’s preferred fundamental physical theory, that they include irreducibly intensive qualities. There are no uninstantiated qualities. I also assume that the fundamental qualitative natures are intrinsic, although physics may ultimately suggest that some of them are extrinsic. On my view, matter, concrete objects, abstract objects, and perhaps even spacetime are constructed from mereological fusions of qualities, so the world is simply a vast mixture of qualities, including polyadic properties (i.e., relations). This means that everything there is, including concrete objects like persons or stars, is a quality, a qualitative fusion, or a portion of the extended qualitative fusion that is the worldwhole. I call my view mereological bundle theory. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Selected Letters by William, Henry JamesWilliam James EarleWilliam and Henry James. Selected Letters. Edited by Ignas K. Skrupskelis and Elizabeth M. Berkeley. Introduction by John J. McDermott. Charlottesville VA: University Press of Virginia, 1997. Pp. xxxi + 570. $ 39.95.Almost fifty years of letters to and from the very diversely brilliant James brothers: in this volume a generous, and probably ample, selection of 216 from a total of (...) 740 surviving letters or postcards, from an original total, according to the present editors, of twice as many. This volume of correspondence reflects the deep, unquestioned, unshakable familial (and virtually statutory) closeness of William and Henry who happened, as adults, to be seldom in the same place. There is, it must be said, very little explicit philosophy, narrowly or broadly defined, in these letters, but the philosophical reader will—or ought to—find much raw material for philosophical reflection. For example, a reasonable historicist thesis of how brotherhood, or family connection generally, plays itself out is supported by these documents. The nineteenth century is not the same as the twentieth. For example, here is William’s comment on the will of his sister, Alice, who left more to her companion and care-giver, Katherine Loring, a [End Page 479] women of extraordinary virtue and burden, than to her brother Robertson: “I can well sympathize with Alice’s desire to leave her something handsome; but I must say that her own consent (being apparently privy to the will) strikes me as tant soit peu lacking in delicacy. Surely no one of us would like to be in such a position in her family or any other” (271). This would be, in 1998, a rather unenlightened and ungenerous attitude, but is natural enough in 1892, even if not quite inevitable, not being shared by Alice herself. There is, incidentally, much discussion of wills and bequests, for the Jameses were of the genteel class, people with small family money and modest private incomes for whom the wherewithal to maintain homes with servants and to provide themselves with country houses and recuperative European vacations was always a faintly embarrassing, and occasionally a pressing, problem.It is probably also true that the much-discussed question of Henry’s homosexuality has, somehow, to be recast in historically relative terms. Here is an early report—1869—of Henry’s from Oxford: “As I walked along the river I saw hundreds of the mighty lads of England, clad in white flannel & blue, immense, fair-haired, magnificent in their youth, lounging down the stream in their punts or pulling in straining crews & rejoicing in their godlike strength” (41). This could not, the point is, be said by anyone, gay or straight, in 1998. Yet Henry is neither generally naive nor uncritically anglophile. He says of the Warwickshire scenery, which in a way he likes, that it is “too monotonously sweet & smooth—too comfortable, too ovine, too bovine, too English in a word.” And he adds, a little surprisingly: “It seems like a vast show region kept up at the expense of the poor” (41). This is only one of many appealing comments not sparsely scattered, but unpredictably, in letters of more ordinary news. Here’s one I liked occasioned by seeing theater in Paris: “We talk about it & write about it & criticize & dogmatize & analyse to the end of time: but those brave players stand forth & exemplify it & act—create—produce!” (66).Of course the “wit and wisdom” are not the monopoly of Henry. Here is William being wise: “We all learn sooner or later that we must gather ourselves up and more or less arbitrarily concentrate our interests, throw much overboard to save any” (55–56). Again: “It is a sweet world, in the interstices of its bedevilment & brutality” (321). And William being funny: “Boils are surely the most slowly evolving things in nature—Christian doctrine is nothing to them” (393). He is talking about his own boils and was subject, at every period, to ailments and infirmities: “Since writing to you, I have been swimming in deep seas of influenza, gout and Erysipelas of the face” (443). Or as he, in 1900, sums it up: “My... (shrink)

Infant language learners are faced with the difficult inductive problem of determining how new words map to novel or known objects in their environment. Bayesian inference models have been successful at using the sparse information available in natural child-directed speech to build candidate lexicons and infer speakers’ referential intentions. We begin by asking how a Bayesian model optimized for monolingual input generalizes to new monolingual or bilingual corpora and find that, especially in the case of the bilingual input, the model (...) shows a significant decrease in performance. In the next experiment, we propose the ME Model, a modified Bayesian model, which approximates infants’ mutual exclusivity bias to support the differential demands of monolingual and bilingual learning situations. The extended model is assessed using the same corpora of real child-directed speech, showing that its performance is more robust against varying input and less dependent than the Intentional Model on optimization of its parsimony parameter. We argue that both monolingual and bilingual demands on word learning are important considerations for a computational model, as they can yield significantly different results than when only one such context is considered.

Philosophical theories of various sorts rely on there being robust boundaries between kinds of content. One way of drawing such boundaries is to place them between subject matters, like physics and aesthetics, and the domains of sentences falling within them. Yet contemporary literature exploring the nature of discourse domains is relatively sparse. The goal of this paper is to articulate the core features of discourse domains for them to provide the sought-after explanatory utility of establishing robust boundaries between discursive contents. (...) Analyzing the role that discourse domains have under alethic theories yields valuable information about the ways in which domains subject themselves to being defined and how alethic theories can explain the variability of truth-aptness or truth across sentences from distinct domains. The concluding argument is that because of certain issues with defining domains as unambiguous classes of sentences when individuated on the grounds of topical subject matters, philosophers should consider a commitment to indeterminism about the extensions of fundamental domains. According to this view, although domains can be defined as relatively well-individuated classes of sentences based on topical distinctions, the temporal development of our conceptual frameworks and the phenomenon of mixed content compromise our ability to definitively account for the domain membership of all truth-apt sentences. Such an indeterminacy argument is relevant for all who rely on there being robust boundaries between topically individuated discursive contents. (shrink)

The paper develops an account of minimal traces devoid of representational content and exploits an analogy to a predictive processing framework of perception. As perception can be regarded as a prediction of the present on the basis of sparse sensory inputs without any representational content, episodic memory can be conceived of as a “prediction of the past” on the basis of a minimal trace, i.e., an informationally sparse, merely causal link to a previous experience. The resulting notion of episodic memory (...) will be validated as a natural kind distinct from imagination. This trace minimalist view contrasts with two theory camps dominating the philosophical debate on memory. On one side, we face versions of the Causal Theory that hold on to the idea that episodic remembering requires a memory trace that causally links the event of remembering to the event of experience and carries over representational content from the content of experience to the content of remembering. The Causal Theory, however, fails to account for the epistemic generativity of episodic memory and is psychologically and information-theoretically implausible. On the other side, a new camp of simulationists is currently forming up. Motivated by empirical and conceptual deficits of the Causal Theory, they reject not only the necessity of preserving representational content, but also the necessity of a causal link between experience and memory. They argue that remembering is nothing but a peculiar form of imagination, peculiar only in that it has been reliably produced and is directed towards an episode of one’s personal past. Albeit sharing their criticism of the Causal Theory and, in particular, rejecting its demand for an intermediary carrier of representational content, the paper argues that a causal connection to experience is still necessary to fulfill even the minimal requirements of past-directedness and reliability.

Tactical deception occurs when an individual is able to use an “honest” act from his normal repertoire in a different context to mislead familiar individuals. Although primates have a reputation for social skill, most primate groups are so intimate that any deception is likely to be subtle and infrequent. Published records are sparse and often anecdotal. We have solicited new records from many primatologists and searched for repeating patterns. This has revealed several different forms of deceptive tactic, which we classify (...) in terms of the function they perform. For each class, we sketch the features of another individual's state of mind that an individual acting with deceptive intent must be able to represent, thus acting as a “natural psychologist.” Our analysis will sharpen attention to apparent taxonomic differences. Before these findings can be generalized, however, behavioral scientists must agree on some fundamental methodological and theoretical questions in the study of the evolution of social cognition.

Sub-Saharan emerging countries experience electrical shortages resulting in power rationing, which ends up hampering economic activities. This paper proposes an approach for very short-term blackout forecast in grid-tied PV systems operating in low reliability weak electric grids of emerging countries. A pilot project was implemented in Arusha-Tanzania; it mainly comprised of a PV-inverter and a lead-acid battery bank connected to the local electricity utility company, Tanzania Electric Supply Company Limited. A very short-term power outage prediction model framework based on a (...) hybrid random forest algorithm was developed using open-source Python machine learning libraries and using a dataset generated from the pilot project’s experimental microgrid. Input data sampled at a 15-minute interval included day of the month, weekday, hour, supply voltage, utility line frequency, and previous days’ blackout profiles. The model was composed of an adaptive similar day module that predicts 15 minutes ahead from a sliding window lookup table spanning 2 weeks prior to the prediction target day, after which ASD prediction was fused with RF prediction, giving a final optimised RF-ASD blackout prediction model. Furthermore, the efficacy analysis of the short-term blackout prediction of the formulated RF, ASD, and RF-ASD regression and classification algorithms was compared. Considering the stochastic nature of blackouts, their performance was found to be fair in short-term blackout predictions of the test site’s weak grid using limited input data from the point of coupling of the user. The models developed were only able to predict blackouts if they occurred frequently and contiguously, but they performed poorly if they were sparse or dispersed. (shrink)

Diverse micro‐organisms populate a global deep biosphere hosted by rocks and sediments beneath land and sea, containing more biomass than any other biome except forests. This paper reviews an emerging palaeobiological archive of these dark habitats: microfossils preserved in ancient pores and fractures in the crust. This archive, seemingly dominated by mineralized filaments (although rods and coccoids are also reported), is presently far too sparsely sampled and poorly understood to reveal trends in the abundance, distribution, or diversity of deep life (...) through time. New research is called for to establish the nature and extent of the fossil record of Earth's deep biosphere by combining systematic exploration, rigorous microanalysis, and experimental studies of both microbial preservation and the formation of abiotic pseudofossils within the crust. It is concluded that the fossil record of Earth's largest microbial habitat may still have much to tell us about the history of life, the evolution of biogeochemical cycles, and the search for life on Mars.

Truth pluralists say that the nature of truth varies between domains of discourse: while ordinary descriptive claims or those of the hard sciences might be true in virtue of corresponding to reality, those concerning ethics, mathematics, institutions might be true in some non-representational or “anti-realist” sense. Despite pluralism attracting increasing amounts of attention, the motivations for the view remain underdeveloped. This paper investigates whether pluralism is well-motivated on ontological grounds: that is, on the basis that different discourses are concerned with (...) different kinds of entities. Arguments that draw on six different ontological contrasts are examined: concrete versus abstract entities; mind-independent versus mind-dependent entities; sparse versus merely abundant properties; objective versus projected entities; natural versus non-natural entities; and ontological pluralism. I argue that the additional premises needed to move from such contrasts to truth pluralism are either implausible or unmotivated, often doing little more than to bifurcate the nature of truth when a more theoretically conservative option is available. If there is a compelling motivation for pluralism, I suggest, it’s likely to lie elsewhere. (shrink)

We present statistical analyses of the large‐scale structure of 3 types of semantic networks: word associations, WordNet, and Roget's Thesaurus. We show that they have a small‐world structure, characterized by sparse connectivity, short average path lengths between words, and strong local clustering. In addition, the distributions of the number of connections follow power laws that indicate a scale‐free pattern of connectivity, with most nodes having relatively few connections joined together through a small number of hubs with many connections. These regularities (...) have also been found in certain other complex natural networks, such as the World Wide Web, but they are not consistent with many conventional models of semantic organization, based on inheritance hierarchies, arbitrarily structured networks, or high‐dimensional vector spaces. We propose that these structures reflect the mechanisms by which semantic networks grow. We describe a simple model for semantic growth, in which each new word or concept is connected to an existing network by differentiating the connectivity pattern of an existing node. This model generates appropriate small‐world statistics and power‐law connectivity distributions, and it also suggests one possible mechanistic basis for the effects of learning history variables (age of acquisition, usage frequency) on behavioral performance in semantic processing tasks.
