We address the question of whether it is possible to operate a time machine by manipulating matter and energy so as to manufacture closed timelike curves. This question has received a great deal of attention in the physics literature, with attempts to prove no- go theorems based on classical general relativity and various hybrid theories serving as steps along the way towards quantum gravity. Despite the effort put into these no-go theorems, there is no widely accepted definition of a time (...) machine. We explain the conundrum that must be faced in providing a satisfactory definition and propose a resolution. Roughly, we require that all extensions of the time machine region contain closed timelike curves; the actions of the time machine operator are then sufficiently "potent" to guarantee that closed timelike curves appear. We then review no-go theorems based on classical general relativity, semi-classical quantum gravity, quantum field theory on curved spacetime, and Euclidean quantum gravity. Our verdict on the question of our title is that no result of sufficient generality to underwrite a confident "yes" has been proven. Our review of the no-go results does, however, highlight several foundational problems at the intersection of general relativity and quantum physics that lend substance to the search for an answer.

Visualizing and mental imagery are thought to be cognitive states by all sides of the imagery debate. Yet the phenomenology of those states has distinctly visual ingredients. This has potential consequences for the hypothesis that vision is cognitively impenetrable, the ability of visual processes to ground perceptual warrant and justification, and the distinction between cognitive and perceptual phenomenology. I explore those consequences by describing two forms of visual ambiguity that involve visualizing: the ability to visually experience a picture surface as (...) flat after it has caused volumetric nonconceptual contents, and the ability to use a surface initially perceived as flat to visualize three-dimensional scenes. In both cases, the visual processes which extract viewer-centered volumetric shapes have to rely solely on monocular depth cues in the absence of parallax and stereopsis. Those processes can be cognitively penetrated by acts of visualizing, including ones that draw on conceptual information about kinds. However, the penetrability of the visual processes does not weaken their ability to provide perceptual warrant and justification for beliefs. The reason is that picture perceptions—whether they are stimulus -driven or based on acts of visualizing—are different to object perceptions both phenomenologically and in terms of their functional roles as states. Thus, although the penetrability of the visual processes does mean that subjects can have visual experiences with contradictory contents, perceptual belief is adopted at most towards one set of contents, and questions of warrant and justification are raised only for those contents. A rule-proving exception is provided by trompe-l’oeils. (shrink)

A philosopher once wrote the following words:If I examine the PTOLOMAIC and COPERNICAN systems, I endeavour only, by my enquiries, to know the real situation of the planets; that is, in other words, I endeavour to give them, in my conception, the same relations, that they bear towards each other in the heavens. To this operation of the mind, therefore, there seems to be always a real, though often an unknown standard, in the nature of things; nor is truth or (...) falsehood variable by the various apprehensions of mankind. Though all human race should for ever conclude, that the sun moves, and the earth remains at rest, the sun stirs not an inch from his place for all these reasonings; and such conclusions are eternally false and erroneous.

Worrall argued that structural realism provides a ‘synthesis’ of the main pro-realist argument – the ‘No Miracles Argument’, and the main anti-realist argument – the ‘Pessimistic Induction’. More recently, however, it has been claimed that each of these arguments is an instance of the same probabilistic fallacy – sometimes called the ‘base-rate fallacy’. If correct, this clearly seems to undermine structural realism and Magnus and Callender have indeed claimed that both arguments are fallacious and ‘without [them] we lose the rationale (...) for … structural realism ’. I here argue that what have been shown to be fallacious are simply misguided formalisations of ‘the’ arguments and that when they are properly construed they continue to provide powerful motivation for favouring structural realism.

This report reviews what quantum physics and information theory have to tell us about the age-old question, How come existence? No escape is evident from four conclusions: (1) The world cannot be a giant machine, ruled by any preestablished continuum physical law. (2) There is no such thing at the microscopic level as space or time or spacetime continuum. (3) The familiar probability function or functional, and wave equation or functional wave equation, of standard quantum theory provide mere continuum idealizations (...) and by reason of this circumstance conceal the information-theoretic source from which they derive. (4) No element in the description of physics shows itself as closer to primordial than the elementary quantum phenomenon, that is, the elementary device-intermediated act of posing a yes-no physical question and eliciting an answer or, in brief, the elementary act of observer-participancy. Otherwise stated, every physical quantity, every it, derives its ultimate significance from bits, binary yes-or-no indications, a conclusion which we epitomize in the phrase, it from bit. (shrink)

This chapter argues that scientific and philosophical progress in our understanding of the living world requires that we abandon a metaphysics of things in favour of one centred on processes. We identify three main empirical motivations for adopting a process ontology in biology: metabolic turnover, life cycles, and ecological interdependence. We show how taking a processual stance in the philosophy of biology enables us to ground existing critiques of essentialism, reductionism, and mechanicism, all of which have traditionally been associated with (...) substance ontology. We illustrate the consequences of embracing an ontology of processes in biology by considering some of its implications for physiology, genetics, evolution, and medicine. And we attempt to locate the subsequent chapters of the book in relation to the position we defend. (shrink)

Do aesthetic reasons have normative authority over us? Could there be anything like an aesthetic ‘ought’ or an aesthetic obligation? I argue that there are no aesthetic obligations. We have reasons to act certain ways regarding various aesthetic objects – most notably, reasons to attend to and appreciate those objects. But, I argue, these reasons never amount to duties. This is because aesthetic reasons are merely evaluative, not deontic. They can only entice us or invite us – they can never (...) compel us. Beauty gives us goods without shoulds. (shrink)

I argue that incomprehensibility (what the ancient skeptics called acatalepsia) plays a central role in the skepticism of both Bayle and Hume. I challenge a commonly held view (recently argued by Todd Ryan) that Hume, unlike Bayle, does not present oppositions of reason--what Kant called antimonies.

In this article I contrast 17th and 18th explanations of hysteria including those of Sydenham and Willis with those given by Plato and pre-modern medicine. I show that beginning in the second decade of the 17th century the locus of the disorder was transferred to the nervous system and it was no longer connected with the womb as in Hippocrates and Galen; hysteria became identified with hypochondria, and was a disease contracted by men as well as women. I discuss the (...) purely mechanical explanation of hysteria given by Robert Boyle who attributed its cause to corporeal ideas as well as overly sensitive disposition of the nervous system. I relate this the mechanical theory of the nervous system prominent in Descartes' writings on physiology. The paper closes with a discussion of the contrast between early modern explanations of hysteria and the nature of man with those of Freud in the early 20th century. (shrink)

This paper argues for the importance of Chapter 33 of Book 2 of Locke's _Essay Concerning Human Understanding_ ("Of the Association of Ideas) both for Locke's own philosophy and for its subsequent reception by Hume. It is argued that in the 4th edition of the Essay of 1700, in which the chapter was added, Locke acknowledged that many beliefs, particularly in religion, are not voluntary and cannot be eradicated through reason and evidence. The author discusses the origins of the chapter (...) in Locke's own earlier writings on madness and in discussions of Enthusiasm in religion. While recognizing association of ideas as derived through custom and habit is the source of prejudice as Locke argued, Hume went on to show how it also is the basis for what Locke himself called "the highest degree of probability", namely "constant and never-failing Experience in like cases" and our belief in “steady and regular Causes.”.

Many policies and ethical guidelines recommend developing “trustworthy AI”. We argue that developing morally trustworthy AI is not only unethical, as it promotes trust in an entity that cannot be trustworthy, but it is also unnecessary for optimal calibration. Instead, we show that reliability, exclusive of moral trust, entails the appropriate normative constraints that enable optimal calibration and mitigate the vulnerability that arises in high-stakes hybrid decision-making environments, without also demanding, as moral trust would, the anthropomorphization of AI and thus (...) epistemically dubious behavior. The normative demands of reliability for inter-agential action are argued to be met by an analogue to procedural metacognitive competence (i.e., the ability to evaluate the quality of one’s own informational states to regulate subsequent action). Drawing on recent empirical findings that suggest providing reliability scores (e.g., F1-scores) to human decision-makers improves calibration in the AI system, we argue that reliability scores provide a good index of competence and enable humans to determine how much they wish to rely on the system.

Country music has not gotten much attention in philosophy. I introduce two philosophical issues that country music raises. First, country music is simple. Some people might think that its simplicity makes country music worse; I argue that simplicity is aesthetically valuable. The second issue is country music’s ideal of authenticity; fans and performers think that country should be real or genuine in a particular way. But country music scholars have debunked the idea that country authenticity gets at anything real; widespread (...) ideas about country authenticity are rooted in a racist and fabricated picture of country music. In discussing these two issues, I highlight the importance of community in country music. (shrink)

Essentialism in philosophy is the position that things, especially kinds of things, have essences, or sets of properties, that all members of the kind must have, and the combination of which only members of the kind do, in fact, have. It is usually thought to derive from classical Greek philosophy and in particular from Aristotle’s notion of “what it is to be” something. In biology, it has been claimed that pre-evolutionary views of living kinds, or as they are sometimes called, (...) “natu-ral kinds”, are essentialist. This static view of living things presumes that no tran-sition is possible in time or form between kinds, and that variation is regarded as accidental or inessential noise rather than important information about taxa. In contrast it is held that Darwinian, and post-Darwinian, biology relies upon varia-tion as important and inevitable properties of taxa, and that taxa are not, therefore, kinds but historical individuals. Recent attempts have been made to undercut this account, and to reinstitute essentialism in biological kind terms. Others argue that essentialism has not ever been a historical reality in biology and its predecessors. In this chapter, I shall outline the many meanings of the notion of essentialism in psychology and social science as well as science, and discuss pro- and anti-essentialist views, and some recent historical revisionism. It turns out that nobody was essentialist to speak of in the sense that is antievolutionary in biology, and that much confusion rests on treating the one word, “essence” as meaning a single notion when in fact there are many. I shall also discuss the philosophical implica-tions of essentialism, and what that means one way or the other for evolutionary biology. Teaching about evolution relies upon narratives of change in the ways the living world is conceived by biologists. This is a core narrative issue. (shrink)

This paper briefly describes process metaphysics, and argues that it is better suited for describing life than the more standard thing, or substance, metaphysics. It then explores the implications of process metaphysics for conceptualizing evolution. After explaining what it is for an organism to be a process, the paper takes up the Hull/Ghiselin thesis of species as individuals and explores the conditions under which a species or lineage could constitute an individual process. It is argued that only sexual species satisfy (...) these conditions, and that within sexual species the degree of organization varies. This, in turn, has important implications for species' evolvability. One important moral is that evolution will work differently in different biological domains. (shrink)

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...) expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

Time in electromagnetism shares many features with time in other physical theories. But there is one aspect of electromagnetism's relationship with time that has always been controversial, yet has not always attracted the limelight it deserves: the electromagnetic arrow of time. Beginning with a re-analysis of a famous argument between Ritz and Einstein over the origins of the radiation arrow, this chapter frames the debate between modern Einsteinians and neo-Ritzians. It tries to find a clean statement of what the arrow (...) is and then explains how it relates to the cosmological and thermodynamic arrows, representing the most developed and sophisticated attack yet, in either the physics or philosophy literature, on the electromagnetic arrow of time.

The vision of natural kinds that is most common in the modern philosophy of biology, particularly with respect to the question whether species and other taxa are natural kinds, is based on a revision of the notion by Mill in A System of Logic. However, there was another conception that Whewell had previously captured well, which taxonomists have always employed, of kinds as being types that need not have necessary and sufficient characters and properties, or essences. These competing views employ (...) different approaches to scientific methodologies: Mill’s class-kinds are not formed by induction but by deduction, while Whewell’s type-kinds are inductive. More recently, phylogenetic kinds (clades, or monophyletic-kinds) are inductively projectible, and escape Mill’s strictures. Mill’s version represents a shift in the notions of kinds from the biological to the physical sciences. (shrink)

Frege’s claim that proper names have senses has come to seem untenable following Kripke’s argument that names are rigid designators. It is commonly thought that if names had senses, their referents would vary with circumstances of evaluation. The article defends Frege’s claim by arguing that names have word-reflexive senses. This analysis of names’ senses does not violate Kripke’s noncircularity condition, and it differs crucially from related views of Bach and Katz. That names have reflexive senses confirms Frege’s own solution to (...) his puzzle about the content of identity sentences, solves Kripke’s Pierre and Peter puzzles about belief ascription, and entails that bearerless names have meanings. Furthermore, names’ having reflexive senses explains why they designate rigidly. (shrink)

One routinely undergoes a noetic feeling (also called “metacognitive feeling” or “epistemic feeling”), the so-called “feeling of knowing”, whenever trying to recall a person’s name. One feels the name is known despite being unable to recall it. Other experiences also fall under this category, e.g., the tip-of-the-tongue experience, the feeling of confidence. A distinguishing characteristic of noetic feelings is how they are crucially related to the facts we know, so much so that the activation of semantic memory can easily result (...) in the production of noetic feelings – a regularity that memory research has often exploited. And yet little is known about the mechanism that produces noetic feelings. Is it solely brain-based or does it depend upon the extracerebral body for its production of feelings? To arrive at an answer, various studies in metamemory research will be analyzed to determine what ought to be made of the mechanism responsible for noetic feelings. I argue that evidence suggests that it relies upon extracerebral processes, in particular cardiovascular processes, the result being support for an embodied view of metacognition. (shrink)

The idea that education should equip people to lead flourishing lives and help others to do so is now becoming salient in policy-making circles. Philosophy of education can help here by clarifying what flourishing consists in. This essay examines one aspect of this. It rejects the view that well-being goods are derivable from human nature, as in the theories of Howard Gardner and Edmond Holmes. It locates them, rather, as cultural products, but not culturally-relative ones, drawing attention to the proliferating (...) forms they have taken over the past three or four centuries. It looks to aesthetics and art criticism as a guide to a philosophical treatment of well-being goods more generally. It also takes off from aesthetics and art criticism in seeking to identify reliable authorities on the flourishing life. On this, it rejects elitist conceptions in favour of a more democratic model, emphasising its importance in education for citizenship. (shrink)

The paper explores the handling of singular analogy in quantitative inductive logics. It concentrates on two analogical patterns coextensive with the traditional argument from analogy: perfect and imperfect analogy. Each is examined within Carnap’s λ-continuum, Carnap’s and Stegmüller’s λ-η continuum, Carnap’s Basic System, Hintikka’s α-λ continuum, and Hintikka’s and Niiniluoto’s K-dimensional system. Itis argued that these logics handle perfect analogies with ease, and that imperfect analogies, while unmanageable in some logics, are quite manageable in others. The paper concludes with a (...) modification of the K-dimensional system that synthesizes independent proposals by Kuipers and Niiniluoto. (shrink)

Everyone will agree that education ought to prepare young people to lead a meaningful life, but there are different ways in which this notion can be understood. A religious interpretation has to be distinguished from the secular one on which this paper focuses. Meaningfulness in this non-religious sense is a necessary condition of a life of well-being, having to do with the nesting of one’s reasons for action within increasingly pervasive structures of activity and attachment. Sometimes a life can seem (...) meaningless when it is not so in fact. In more extreme cases it may in fact be to some extent meaningless. Equipping young people for a meaningful life is a worthwhile, but not all-important educational aim. Educators should help them not only to see their lives as meaningful but also to lead lives that <are> meaningful. This involves continuous engagement in the nesting of reasons mentioned above. Where autonomy is also an aim, temperamental attunement to possible options – rather than exposure to all possible options – and time to explore them are important considerations. Questions arise here both about social justice and about whether current school curriculum and timetabling arrangements help or hinder pupils in living a meaningful life. (shrink)

The relation between body and mind is one of the oldest riddles that has puzzled mankind. That material and mental events may interact is accepted even by the law: our mental capacity to concentrate on the task can be seriously reduced by drugs. Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical events, upon the mind of the recipient of the (...) letter. This is what the authors of this book call the 'interaction of mental and physical events'. We know very little about this interaction; and according to recent philosophical fashions this is explained by the alleged fact that we have brains but no thoughts. The authors of this book stress that they cannot solve the body mind problem; but they hope that they have been able to shed new light on it. Eccles especially with his theory that the brain is a detector and amplifier; a theory that has given rise to important new developments, including new and exciting experiments; and Popper with his highly controversial theory of 'World 3'. They show that certain fashionable solutions which have been offered fail to understand the seriousness of the problems of the emergence of life, or consciousness and of the creativity of our minds. In Part I, Popper discusses the philosophical issue between dualist or even pluralist interaction on the one side, and materialism and parallelism on the other. There is also a historical review of these issues. In Part II, Eccles examines the mind from the neurological standpoint: the structure of the brain and its functional performance under normal as well as abnormal circumstances. The result is a radical and intriguing hypothesis on the interaction between mental events and detailed neurological occurrences in the cerebral cortex. Part III, based on twelve recorded conversations, reflects the exciting exchange between the authors as they attempt to come to terms with their opinions. (shrink)

Richard Peters argued for a general education based largely on the study of truth-seeking subjects for its own sake. His arguments have long been acknowledged as problematic. There are also difficulties with Paul Hirst's arguments for a liberal education, which in part overlap with Peters'. Where justification fails, can historical explanation illuminate? Peters was influenced by the prevailing idea that a secondary education should be based on traditional, largely knowledge-orientated subjects, pursued for intrinsic as well as practical ends. Does history (...) reveal good reasons for this view? The view itself has roots going back to the 16th century and the educational tradition of radical Protestantism. Religious arguments to do with restoring the image of an omniscient God in man made good sense, within their own terms, of an encyclopaedic approach to education. As these faded in prominence after 1800, old curricular patterns persisted in the drive for ‘middle-class schools’, and new, less plausible justifications grew in salience. These were based first on faculty psychology and later on the psychology of individual differences. The essay relates the views of Peters and Hirst to these historical arguments, asking how far their writings show traces of the religious argument mentioned, and how their views on education and the development of mind relate to the psychological arguments.

Abstract Charles Darwin, in his discussions with Asa Gray and in his published works, doubted whether God could so arrange it that exactly the desired contingent events would occur to cause particular outcomes by natural selection. In this paper, I argue that even a limited or neo-Leibnizian deity could have chosen a world that satisfied some arbitrary set of goals or functions in its outcomes and thus answer Darwin's conundrum. In more general terms, this supports the consistency of natural selection (...) with providentialism, and makes “theistic evolutionism” a coherent position to hold. (shrink)

In England and Wales we have had a National Curriculum since 1988. How can it have survived so long without aims to guide it? This IMPACT pamphlet argues that curriculum planning should begin not with a boxed set of academic subjects of a familiar sort, but with wider considerations of what schools should be for. We first work out a defensible set of wider aims backed by a well-argued rationale. From these we develop sub-aims constituting an aims-based curriculum. Further detail (...) is provided here on one of the most central educational aims, to do with equipping each child to live a flourishing personal and civic life.

Genes are thought to have evolved from long-lived and multiply-interactive molecules in the early stages of the origins of life. However, at that stage there were no replicators, and the distinction between interactors and replicators did not yet apply. Nevertheless, the process of evolution that proceeded from initial autocatalytic hypercycles to full organisms was a Darwinian process of selection of favourable variants. We distinguish therefore between Neo-Darwinian evolution and the related Weismannian and Central Dogma divisions, on the one hand, and (...) the more generic category of Darwinian evolution on the other. We argue that Hull’s and Dawkins’ replicator/interactor distinction of entities is a sufficient, but not necessary, condition for Darwinian evolution to take place. We conceive the origin of genes as a separation between different types of molecules in a thermodynamic state space, and employ a notion of reproducers. (shrink)

The Double Content view is the first comprehensive theory of art that is able to satisfactorily explain the nature of all kinds of artworks in a unified way — whether paintings, novels, or musical and theatrical performances. The basic thesis is that all such representational artworks involve two levels or kinds of representation: a first stage in which a concrete artifact represents an artwork, and a second stage in which that artwork in turn represents its subject matter. "Dilworth applies his (...) theory across the arts and to a variety of issues, demonstrating that it has far-reaching implications for our philosophical understanding of the nature of art.” - Stephen Davies, Associate Professor of Philosophy, University of Auckland..

Causal theories of perception typically have problems in explaining deviant causal chains. They also have difficulty with other unusual putative cases of perception involving prosthetic aids, defective perception, scientifically extended cases of perception, and so on. But I show how a more adequate reflexive causal theory, in which objects or properties X cause a perceiver to acquire X-related dispositions toward that very same item X, can provide a plausible and principled perceptual explanation of all of these kinds of cases. A (...) critical discussion of David Lewis's perceptual descriptivist views is also provided, including a defense of the logical possibility of systematic misperception or perceptual error for a perceiver, in spite of its empirical improbability.

The outlines of a novel, fully naturalistic theory of perception are provided, that can explain perception of an object X by organism Z in terms of reflexive causality. On the reflexive view proposed, organism Z perceives object or property X just in case X causes Z to acquire causal dispositions reflexively directed back upon X itself. This broadly functionalist theory is potentially capable of explaining both perceptual representation and perceptual content in purely causal terms, making no use of informational concepts. (...) However, such a reflexive, naturalistic causal theory must compete with well entrenched, supposedly equally naturalistic theories of perception that are based on some concept of information, so the paper also includes some basic logical, naturalistic and explanatory criticisms of such informational views. (shrink)

ABSTRACT: The Reflexive Theory of Perception (RTP) claims that perception of an object or property X by an organism Z consists in Z being caused by X to acquire some disposition D toward X itself. This broadly behavioral perceptual theory explains perceptual intentionality and correct versus incorrect, plus successful versus unsuccessful, perception in a plausible evolutionary framework. The theory also undermines cognitive and perceptual modularity assumptions, including informational or purely epistemic views of perception in that, according to the RTP, any (...) X-caused and X-directed dispositions are genuinely perceptual—including affective, attitudinal, and immediately activated purely action-directed behavioral dispositions. Thus the RTP has the potential to provide the foundations for a broadly behavioral counter-revolution in cognitive science. (shrink)

Elijah Chudnoff’s case for irreducible cognitive phenomenology hinges on seeming to see the truth of a mathematical proposition (Chudnoff 2015). In the following, I develop an augmented version of Chudnoff’s case, not based on seeming to see, or intuition, but based on being in a state with presentational phenomenology of high-level content. In contrast to other cases for cognitive phenomenology, those based on Strawson’s case (Strawson 2011), I argue that the case presented here is able to withstand counterarguments, which attempt (...) to reduce cognitive phenomenology to sensory phenomenology. To support my argument, I present findings from Bowden and Jung-Beeman’s experiments with the Aha! Experience (Bowden & Jung-Beeman 2004), and argue that the Aha! Experience is a species of the experience of understanding presented here. I interpret the results of these experiments to provide further evidence for irreducible cognitive phenomenology. (shrink)

The artefacts produced by artists during their creation of works of art are very various: paintings, writings, musical scores, and so on. I have a general thesis to offer about the relations of artefacts and artworks, but within the confines of this article I shall mainly discuss cases drawn from the art of painting, central specimens of which seem to be autographic in Nelson Goodman's sense, namely such that even the most exact duplication of them does not count as producing (...) the same work of art. My view will be that an artwork (such as a painting) and its associated artefact are not identical, and nor is the artefact in any sense part of the painting in question,2 but that nevertheless it is still possible to maintain the view that paintings are autographic (which view I shall call l the autographic thesis). I shall proceed initially through presentation of some counter-examples to common assumptions as to the relations of artefacts and artworks, and then present an alternative 'representational' theory of their relations.

This paper will investigate the basic question of the nature of perception, as theoretically approached from a purely naturalistic standpoint. An adequate theory must not only have clear application to a world full of pre-existing biological examples of perception of all kinds, from unicellular perception to conscious human perception, but it must also satisfy a series of theoretical or philosophical constraints, as enumerated and discussed in Section 1 below. A perceptual theory invoking _reflexive dispositions_--that is, dispositions directed toward the very (...) same worldly perceived objects or properties that caused them--will be defended as one legitimate such naturalistic theory.

Actual situations where folk philosophy might have predicted precognition effects were studied and dealt with experimentally and theoretically. Extremely strong experimental results were obtained but the findings supported not precognition but the Many Bubble Interpretation, which uses at this time dynamical systems theory as applied to the physics of the brain. Further experiments and theoretical work were discussed.

The idea of dreams being mere internal artifacts of the mind does not seem to be essential to externalism and extended mind theories, which seem as if they would function as well without this additional assumption. The Many Bubble Interpretation could allow a simpler rationale to externalist theories, which may be even simpler if the assumption that dreams have no worthwhile content outside the mind is omitted.

Present progress in mind science is racing away in the direction of denying the existence of human freewill and animal and human sentience.

I argue that the physical marks on a canvas resulting from an artist's intentional, stylistic and expressive acts cannot themselves be the artist's expression, but instead they serve to signify or indicate those acts. Thus there is a kind of indicative content associated with a picture that is distinct from its subject matter (or 'representational content'). I also argue that this kind of indicative content is closely associated with the specific artistic medium chosen by the artist as her expressive medium, (...) for which reason I call this kind of content medium content (or medium-related content).

The field of machine perception is based on standard informational and computational approaches to perception. But naturalistic informational theories are widely regarded as being inadequate, while purely syntactic computational approaches give no account of perceptual content. Thus there is a significant need for a novel, purely naturalistic perceptual theory not based on informational or computational concepts, which could provide a new paradigm for mechanistic perception. Now specifically evolutionary naturalistic approaches to perception have been—perhaps surprisingly—almost completely neglected for this purpose. Arguably (...) perceptual mechanisms enhance evolutionary fitness by facilitating sensorily mediated causal interactions between an organism Z and items X in its environment. A ‘reflexive’ theory of perception of this kind is outlined, according to which an organism Z perceives an item X just in case X causes a sensory organ zi of Z to cause Z to acquire a disposition toward the very same item X that caused the perception. The rest of the paper shows how an intuitively plausible account of mechanistic perception can be developed and defended in terms of the reflexive theory. Also, a compatibilist option is provided for those who wish to preserve a distinct informational concept of perception. (shrink)

In Languages of Art, Nelson Goodman presents a general theory of symbolic notation. However, I show that his theory could not adequately explain possible cases of natural language notational uses, and argue that this outcome undermines, not only Goodman's own theory, but any broadly type versus token based account of notational structure.Given this failure, an alternative representational theory is proposed, in which different visual or perceptual aspects of a given physical inscription each represent a different letter, word, or other notational (...) item. Such a view is strongly supported by the completely conventional relation between inscriptions and notation, as shown by encryption techniques etc. (shrink)

Scholars of ideology in social-scientific disciplines, including psychology, sociology, and political science, stand to benefit from taking seriously the philosophical contributions of Professor Peter Railton. This is because Railton provides much-needed conceptual precision—and a rare sense of epistemological and moral clarity—to a topic that is notoriously slippery and prone to relativistic musing and the drawing of false equivalences. In an essay entitled “Morality, Ideology, and Reflection: Or, the Duck Sits Yet,” Railton (2000/2003) aptly identified the purpose of ideological analysis as (...) the unmasking of “nonepistemic” interests—that is, interests other than truth-seeking, accuracy, or warrant —that contribute to the development, adoption, and dissemination of political and religious belief systems.

Clearly we can perceive both objects, and various aspects or appearances of those objects. But how should that complexity of perceptual content be explained or analyzed? I argue that perceptual representations normally have a double or two level nested structure of content, so as to adequately incorporate information both about contextual aspects Y(X) of an object X, and about the object X itself. On this double content (DC) view, perceptual processing starts with aspectual data Y?(X?) as a higher level of (...) content, which data does not itself provide lower level X-related content, but only an aspectually encoded form of such data. Hence the relevant perceptual data Y?(X?) must be. (shrink)

It is generally accepted that Mill’s classification of names as nonconnotative terms is incompatible with Frege’s thesis that names have senses. However, Milldescribed the senses of nonconnotative terms—without being aware that he was doing so. These are the senses for names that were sought in vain by Frege. When Mill’s and Frege’s doctrines are understood as complementary, they constitute a fully satisfactory theory of names.
