The levels that compose biological hierarchies each have their own energetic, spatial and temporal structure. Indeed, it is the discontinuity in energy relationships between levels, as well as the similarity of sub-systems that support them, that permits levels to be defined. In this paper, the temporal structure of living hierarchies, in particular that pertaining to Human society, is examined. Consideration is given to the period defining the lifespan of entities at each level and to a periodic event considered fundamental to (...) the maintenance of that level. The ratio between the duration of these two periods is found to be approximately 2.5 × 104. A similar relationship is found when lower, non-living levels of molecules and atoms are considered. This suggests that there is a constant factor of amplification between analogous periodic events at successive levels of the Human hierarchy. (shrink)

There is a certain measure of perplexity concerning the significance of endopolyploidy. It seems that this results from a narrow frame of reference from which investigators view the phenomenon; that is, a predilection for emphasizing the specialized functional aspect of endopolyploidy as it operates in species at the present time overrides any consideration of the rôle that this state may play in the life of a species in its encounter with the forces of natural selection either in the past or (...) in the future.There does not seem to be any obvious relationship between the degree of endopolyploidy that a species can exhibit and either its basic DNA content or the structure of its nucleus. The significance of endopolyploidy may reside not so much in any specialized function that the condition can support, but rather in the properties that are consequent upon the endopolyploid condition itself and which are distinct from those that apply to diploid cells. Some of the properties of the endopolyploid state, and examples of their manifestation in plants and animals, are discussed. The conclusion is that these properties have a potential that opens possibilities for new paths of development and serves as a factor upon which natural selection can operate. (shrink)

In this paper I defend an account of the nature of propositional content according to which the proposition expressed by a declarative sentence is a certain type of action a speaker performs in uttering that sentence. On this view, the semantic contents of proper names turn out to be types of reference acts. By carefully individuating these types, it is possible to provide new solutions to Frege’s puzzles about names in identity- and belief-sentences.

Dynamical Grammar explores the consequences for language acquisition, language evolution, and linguistic theory of taking the underlying architecture of the language faculty to be that of a complex adaptive dynamical system. It contains the first results of a new and complex model of language acquisition which the authors have developed to measure how far language input is reflected in language output and thereby get a better idea of just how far the human language faculty is hard-wired.

In 1913 Wittgenstein raised an objection to Russell’s multiple relation theory of judgment that eventually led Russell to abandon his theory. As he put it in the Tractatus, the objection was that “the correct explanation of the form of the proposition, ‘A makes the judgement p’, must show that it is impossible for a judgement to be a piece of nonsense. (Russell’s theory does not satisfy this requirement,” (5.5422). This objection has been widely interpreted to concern type restrictions on the (...) constituents of judgment. I argue that this interpretation is mistaken and that Wittgenstein’s objection is in fact a form of the problem of the unity of the proposition. (shrink)

According to color subjectivism, colors are mental properties, processes, or events of visual experiences of color. I first lay out an argument for subjectivism founded on claims from visual science and show that it also relies on a philosophical assumption. I then argue that subjectivism is untenable because this view cannot provide a plausible account of color perception. I describe three versions of subjectivism, each of which combines subjectivism with a theory of perception, namely sense datum theory, adverbialism, and the (...) virtual color proposal, and argue that each version faces serious objections. Considering these three theories of perception to be exhaustive of those available to the subjectivist, I conclude that subjectivism is untenable and that the scientifically motivated argument for this view is unsound. I then offer the diagnosis that the philosophical assumption on which this argument relies is mistaken. (shrink)

To deal with syntactic structure, one needs to go beyond a simple model based on associative structures, and to adopt a dynamical systems perspective, where each phrase and sentence of a language is represented as a trajectory in a syntactic phase space. Neural assemblies could possibly be used to produce dynamics that in principle could handle syntax along these lines.

A first-person proposition is a proposition that only a single subject can assert or believe. When I assert ‘I am on fire’ I assert a first-person proposition that only I have access to, in the sense that no one else can assert or believe this proposition. This is in contrast to third-person propositions, which can be asserted or believed by anyone.

What moral standards ought nation-states abide by when selecting immigration policies? Peter Higgins argues that immigration policies can only be judged by considering the inequalities that are produced by the institutions - such as gender, race and class - that constitute our social world.Higgins challenges conventional positions on immigration justice, including the view that states have a right to choose whatever immigration policies they like, or that all immigration restrictions ought to be eliminated and borders opened. Rather than suggesting (...) one absolute solution, he argues that a unique set of immigration policies will be just for each country. He concludes with concrete recommendations for policymaking.

The problem of the source of necessity is the problem of explaining what makes necessary truths necessarily true. Simon Blackburn has presented a dilemma intended to show that any reductive, realist account of the source of necessity is bound to fail. Although Blackburn's dilemma faces serious problems, reflection on the form of explanations of necessities reveals that a revised dilemma succeeds in defeating any reductive account of the source of necessity. The lesson is that necessity is metaphysically primitive and irreducible.

Wood and Spekkens argue that any causal model explaining the EPRB correlations and satisfying the no-signalling constraint must also violate the assumption that the model faithfully reproduces the statistical dependences and independences—a so-called ‘fine-tuning’ of the causal parameters. This includes, in particular, retrocausal explanations of the EPRB correlations. I consider this analysis with a view to enumerating the possible responses an advocate of retrocausal explanations might propose. I focus on the response of Näger, who argues that the central ideas of (...) causal explanations can be saved if one accepts the possibility of a stable fine-tuning of the causal parameters. I argue that in light of this view, a violation of faithfulness does not necessarily rule out retrocausal explanations of the EPRB correlations. However, when we consider a plausible retrocausal picture in some detail, it becomes clear that the causal modelling framework is not a natural arena for representing such an account of retrocausality. _1_ Causal Models, Quantum Mechanics, and Faithfulness _2_ Fine-Tuning _2.1_ Fine-tuning in a retrocausal model _3_ Possible Responses _4_ Quantum Causal Models and Retrocausality _4.1_ A more detailed retrocausal account _4.2_ A model of the EPRB probabilities _4.3_ Mapping to a causal model _5_ Conclusion.

Karl Marx’s acerbic observation in the opening lines of _The Eighteenth Brumaire_ that “all facts and personages of great importance in world history occur the first time as tragedy, the second as farce” may be profitably applied to a reconsideration of literary farce sui generis, a genre represented in this article by a long-neglected work of utopian fiction, Archibald Marshall’s _Upsidonia_ (1915). Although _Upsidonia_’s current disregard is arguably undeserved, the article’s chief interest is not to reclaim the novel on aesthetic (...) grounds but to illuminate the mechanics of what Marx would call its “serious buffoonery.” In its persistent reversal of capitalist principles and relations, _Upsidonia_ naturally invites readers to revisit Marx, whose mordant gambit may serve as a key to Marshall’s own farcical plot and praxis, rooted in return and repetition, the essential maneuvers of farce itself.

What legal rights and duties immigrants should have is among the most ferociously debated topics in the politics of liberal societies today. However, as this article will show, there is remarkably little disagreement of great magnitude among political theorists and philosophers of immigration on the rights and duties of resident immigrants (even in contrast to the closely related philosophical discussion of justice in immigrant admissions). Specifically, this article will survey philosophical positions both on what legal rights immigrants (documented permanent residents, (...) guestworkers, and undocumented immigrants) ought to have (including to citizenship and against deportation), and on what liberal societies may justly do to require immigrants to integrate. This article will reveal that there is a substantial, growing gap between contemporary politics worldwide and what the moral norms of liberalism seem to entail concerning the rights and duties of immigrants.

Adults and infants display a robust ability to perceive the unity of a center-occluded object when the visible ends of the object undergo common motion (e.g. Kellman, P.J., Spelke, E.S., 1983. Perception of partly occluded objects in infancy. Cognitive Psychology 15, 483±524). Ecologically oriented accounts of this ability focus on the primacy of motion in the perception of segregated objects, but Gestalt theory suggests a broader possibility: observers may perceive object unity by detecting patterns of synchronous change, of which common (...) motion is a special case. We investigated this possibility with observations of adults and 4-month-old infants. Participants viewed a center-occluded object whose visible surfaces were either misaligned or aligned, stationary or moving, and unchanging or synchronously changing in color or bright- ness in various temporal patterns (e.g. ¯ashing). Both alignment and common motion con- tributed to adults' perception of object unity, but synchronous color changes did not. For infants, motion was an important determinant of object unity, but other synchronous changes and edge alignment were not. When a stationary object with aligned edges underwent syn- chronous changes in color or brightness, infants showed high levels of attention to the object, but their perception of its unity appeared to be indeterminate. An inherent preference for fast over slow ¯ash rates, and a novelty preference elicited by a change in rate, both indicated that infants detected the synchronous changes, although they failed to use them as information for object unity. These ®ndings favor ecologically oriented accounts of object perception in which surface motion plays a privileged role. Ó 1999 Elsevier Science B.V. All rights reserved. (shrink)

The problem of the nature of color is typically put in terms of the following question about the intentional content of visual experiences: what’s the nature of the property we attribute to physical objects in virtue of our visual experiences of color? This problem has proven to be tenacious largely because it’s not clear what the constraints are for an answer. With no clarity about constraints, the proposed solutions range widely, the most common dividing into subjectivist views which hold that (...) attributed colors are mental properties or mental events} and a variety of realist views, which hold that colors are properties of physical objects. These realist views, in turn, divide into views that hold that attributed colors are dispositions of physical objects to produce color experiences (dispositionalism),° nondispositional relations between objects and perceivers (the relational view)," physical properties of physical objects (physicalism),‘ or sui generis properties of physical objects (primitivism and impressionism).‘ I’ll examine a proposed constraint which Mark Johnston (1992) calls Revelation. According to Revelation, the appearance of color in our ordinary visual experience provides us with unqualified access to the nature of color. While every proposal about the nature of color must take a stand on how the.. (shrink)

In order for a state to rightfully exercise self-determination by means of setting policies concerning migrants and migration, they must be legitimate, Gillian Brock argues in _Justice for People on the Move_. Legitimacy, in Brock’s view, requires that states satisfy three (jointly sufficient) conditions: they must respect their own citizens’ human rights; they must be a part of a legitimate state system; and they must adequately contribute to the maintenance of this state system. In her new book, Brock also argues (...) persuasively for a variety of migration-related policies that states ought to adopt (concerning, for example, addressing the needs of refugees, regularization of undocumented migrants, and protections for temporary labor migrants). In previous work (Brock, _Global Justice: A Cosmopolitan Account_, Oxford University Press, New York, 2009; Brock and Blake, _Debating Brain Drain: May Governments Restrict Emigration?_, Oxford University Press, New York, 2015), Brock has compellingly defended the justice of policies designed to allay the harmful effects of brain drain. In this commentary, I wish to argue that the legitimacy standard Brock defends in _Justice for People on the Move_ is an obstacle to the justified adoption of the migration-related policies Brock demonstrates here and in previous work to be substantively morally justified, if not required by justice. If a state is not legitimate, then it lacks the moral standing to adopt migration policies that are otherwise morally justified. I do not intend to question the importance of the concept of state legitimacy for political philosophy generally. However, I wish to argue that that in the context of migration justice, considerations of state legitimacy may be contrary to the goal of defending a view on what policies a state ought to adopt. It may be more useful simply to consider whether or not there is moral justification for a particular state to adopt a particular policy. (shrink)

There has been in recent years a huge surge of interest in the so-called extended Wigner’s friend scenario (EWFS). In short, a series of theorems (with some variation in detail) puts pressure on the ability of different agents in the scenario to account for each of the others’ measured outcomes: the outcomes cannot be assigned single well-defined values while also satisfying other reasonable physical assumptions. These theorems have been interpreted as showing that there can be no absolute, third-person, ‘God’s eye’ (...) description of our reality. The focus of this paper is the strongest of these no-go theorems, the ‘local friendliness’ theorem of Bong et al. (2020, _Nature Physics_, _16_, 1199–1205), which gives earnest consideration to the possibility of a measurement that unitarily reverses an entire lab system, including a conscious agent, thereby erasing the agent’s memory. The purpose of this paper is to begin the philosophical conversation regarding key questions concerning this process: Are the events in the lab merely ‘erased’, or do they in some sense not exist at all? What would it be like to be unitarily reversed? Should an agent care about any experiences they have inside the lab before they are reversed? This analysis employs a parallel case of memory erasure, to which this case can be contrasted, arising in the context of drug-induced amnesia as a result of administering anaesthesia during medical procedures (Carbonell, 2014, _Bioethics_, _28_(5), 245–254). I argue that the consequences of unitarily reversing an agent are much more dramatic than simply memory erasure—the set of events themselves, and the personal timeline of the agent, leave no record at all inside or outside the lab. I consider the ramifications of this for the picture of reality that arises from the EWFS. (shrink)

How should we characterize the nature of perceptual experience? Some theorists claim that colour experiences, to take an example of perceptual experiences, have both intentional properties and properties called 'colour qualia', namely, mental qualitative properties which are what it is like to be conscious of colour. Since proponents of colour qualia hold that these mental properties cannot be explained in terms of causal relations, this position is in opposition to a functionalist characterization of colour experience.

We describe some of the signs and symptoms of left visuo-spatial neglect. This common, severe and often long-lasting impairment is the most striking consequence of right hemisphere brain damage. Patients seem to (over-)attend to the right with subsequent inability to respond to stimuli in contralesional space. We draw particular attention to how patients themselves experience neglect. Furthermore, we show that the neglect patient's loss of awareness of left space is crucial to an understanding of the condition. Even after left space (...) has been brought into the patient's consciousness (either by local cueing on the left or by an emphasis on global properties of the scene as a whole), this awareness of left space rapidly declines. We suggest that much of the symptomology of left neglect can be interpreted as a disconnection between brain mechanisms that are relatively specialized for local (detail) visual processing and global (panoramic) processing. This failure of communication between functional (subpersonal) mechanisms then has consequences for how perceptual and representational content enters into awareness. Failure of the local contents of left space to be consciously accessed is, in turn, an important aspect of why left neglect is so difficult to remediate. Patients can ''know'' that they have neglect but are cut off from the perceptual awareness that would enable them to overcome their attentional bias to the right. (shrink)

In Jackendoff's Parallel Architecture, the well-formed expressions of a language are licensed by correspondences between phonology, syntax, and conceptual structure. I show how this architecture can be used to make sense of the existence of parasitic gap constructions. A parasitic gap is one that is rendered acceptable because of the presence of another gap in the same sentence. Compare *a person whoi everyone who talks to ti likes Chris, which shows an illicit extraction from a relative clause, and a person (...) whoi everyone who talks to pgi likes ti, which shows a parasitic gap in the relative clause. Languages differ in terms of the range of configurations in which they allow parasitic gaps; these configurations appear to form a hierarchy. These observations raise some fundamental questions: Why do parasitic gaps exist at all? Why are different syntactic configurations possible for P-gaps and why just these configurations? Why is there a parasitic gap hierarchy? The answers that I propose make crucial use of constructional overgeneralization of across-the-board extraction in coordinate constructions, formulated straightforwardly in the framework of Jackendoff's Parallel Architecture.

It is the prevailing paradigm in contemporary physics to model the dynamical evolution of physical systems in terms of a real parameter conventionally denoted as 't' ('little tee'). We typically call such dynamical models laws of nature' and t we call 'physical time'. It is common in the philosophy of time to regard t as time itself, and to take the global structure of general relativity as the ultimate guide to physical time, and so consequently the true nature of time. (...) In this paper we defend the idea that physical time, t, is rather better defined as an operational modelling parameter: we measure relations between changing physical quantities using bespoke physical systems---i.e. clocks---that coordinate local coincidences. We argue that the sorts of physical systems that make good clocks---what we call precision clocks---are those that exhibit self-sustained oscillations known as limit cycles, which are ubiquitous in open, driven, stable, dissipative systems. We develop the physical and philosophical ramifications of this conception of physical time, particularly the notion that physical time does not track something 'out there' in the world. As a result, we speculate that physical time is perhaps not as different from manifest time as many philosophers of time (and apparently general relativity) seem to suggest. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Capitalism in “Wealthy Hellas”? PETER W. ROSE Josiah ober has taken on the very ambitious task of analyzing a vast swath of ancient Greek history— precisely the periods—as his opening quotation from Byron (1) implies—most admired by those who have devoted any time to the study of Greek antiquity: Fair Greece! sad relic of departed worth! Immortal, though no more! Though fallen, great!1 At the same time, again (...) as suggested by the repetition of Byron’s lines (206, also mentioned on 293), Ober’s book falls within the large category of celebratory works about ancient Greece—like Werner Jaeger’s once popular three volumes of Paideia or, at the outset of the twentieth century, Alfred Zimmern ’s The Greek Commonwealth.2 It does not, on the other hand, fit in with a plethora of relatively recent, relatively short (as opposed to George Grote’s twelve volumes) histories of Greece aimed at the potentially lucrative textbook market for general more comprehensive overviews of Greek civilization.3 As such, the basis on which Ober celebrates ancient Greece merits close scrutiny. history and the overriding thesis ober’s conception of “history” here is heavily weighted towards the theoretical elaboration and justification of an Josiah Ober, The Rise and Fall of Classical Greece (Princeton University Press 2015), hardback, 415 pages.

Five initial chapters of a total of eleven are devoted to that task before five chronologically focused chapters, which offer a cursory romp through Greek history from ca. 1000 BCE to 334 BCE and some brief suggestions about the period down to the decisive takeover of Greece by Rome, usually dated to 31 BCE. The volume is capped by a final summary and overview chapter. Ober is admirably forthright about his agenda. Immediately in his preface he declares, “in states where citizens keep rulers in check, public authority protects individual rights and the rule of law pertains most of the time. These political conditions promote economic growth. The conjunction of democratic politics and a strong economy is, in practice, available only to affluent citizens of highly developed countries.... Democracy and growth define the normal, although not yet the usual, conditions of modernity” (xiii, my emphasis).4 This somewhat utopian conception of the present-day interface of democratic institutions and economic growth—posited as an unquestioned desideratum in sublime disregard of “ecology” in the literal sense5—underlies Ober’s whole project. While acknowledging the obvious negatives of ancient slavery,6 “denial of rights to women, and glorified war,” he argues “if we are interested in the conjunction of political and economic exceptionalism, we must start somewhere, and classical Greece was the society in which the wealth-and-democracy package first emerged in a form that can be studied in depth” (xv). Athenian democracy has been at the center of Ober’s impressive scholarly career at least since the publication of his study of fourth-century BCE Athenian rhetoric, Mass and Elite in Democratic Athens (Princeton 1989). “Athens” or “democracy” have featured in the titles of all his subsequent book publications7—not to mention the extraordinary output of more specialized essays in multiple venues. One overriding question about his latest book is whether the unique phenomenon of Athenian democracy is being unduly generalized to “Classical Greece.” 142 capitalism in “wealthy hellas”? The special focus of his interest here in ancient Greece, the “conjunction of political and economic exceptionalism,” is further clarified in his opening chapter which begins with the quotation from Byron cited above: “Byron’s vision of greatness was inspired by ancient Greek cultural and intellectual achievement: art and architecture, literature, visual and performance art, scientific and moral thought.... Hellas was great because of a cultural accomplishment that was supported by sustained economic growth. That growth was made possible by a distinctive approach to politics” (1–2). Greek cultural achievements, however, are bracketed (and in practical terms dismissed)8 in favor of the “wealth-anddemocracy... (shrink)

Palmer demarcates the bounds of our understanding of color experience by symmetries in the color space. He claims that if there are symmetries, there can be functionally undetectable color transformations. However, even if there are symmetries, Palmer's support for the possibility of undetectable transformations assumes phenomenal internalism. Alternatively, phenomenal externalism eliminates Palmer's limit on our understanding of color experience.

A recent series of experiments have demonstrated that a classical fluid mechanical system, constituted by an oil droplet bouncing on a vibrating fluid surface, can be induced to display a number of behaviours previously considered to be distinctly quantum. To explain this correspondence it has been suggested that the fluid mechanical system provides a single-particle classical model of de Broglie’s idiosyncratic ‘double solution’ pilot wave theory of quantum mechanics. In this paper we assess the epistemic function of the bouncing oil (...) droplet experiments in relation to quantum mechanics. We find that the bouncing oil droplets are best conceived as an analogue illustration of quantum phenomena, rather than an analogue simulation, and, furthermore, that their epistemic value should be understood in terms of how-possibly explanation, rather than confirmation. Analogue illustration, unlike analogue simulation, is not a form of ‘material surrogacy’, in which source empirical phenomena in a system of one kind can be understood as ‘standing in for’ target phenomena in a system of another kind. Rather, analogue illustration leverages a correspondence between certain empirical phenomena displayed by a source system and aspects of the ontology of a target system. On the one hand, this limits the potential inferential power of analogue illustrations, but, on the other, it widens their potential inferential scope. In particular, through analogue illustration we can learn, in the sense of gaining how-possibly understanding, about the putative ontology of a target system via an experiment. As such, the potential scientific value of these extraordinary experiments is undoubtedly a significant one. (shrink)

Consciousness as used here, refers to the private, subjective experience of being aware of our perceptions, thoughts, feelings, actions, memories including the intimate experience of a unified self with the capacity to generate and control actions and psychological contents. This compelling, intuitive consciousness-centric account has, and continues to shape folk and scientific accounts of psychology and human behavior. Over the last 30 years, research from the cognitive neurosciences has challenged this intuitive social construct account when providing a neurocognitive architecture for (...) a human psychology. Growing evidence suggests that the executive functions typically attributed to the experience of consciousness are carried out competently, backstage and outside subjective awareness by a myriad of fast, efficient non-conscious brain systems. While it remains unclear how and where the experience of consciousness is generated in the brain, we suggested that the traditional intuitive explanation that consciousness is causally efficacious is wrong-headed when providing a cognitive neuroscientific account of human psychology. Notwithstanding the compelling 1st-person experience that convinces us that subjective awareness is the mental curator of our actions and thoughts, we argue that the best framework for building a scientific account is to be consistent with the biophysical causal dependency of prior neural processes. From a 3rd person perspective,, we propose that subjective awareness lacking causal influence, is than our experience of being aware, our awareness of our psychological content, knowing that we are aware, and the belief that that such experiences are evidence of an agentive capacity shared by others. While the human mind can be described as comprising both conscious and nonconscious aspects, both ultimately depend on neural process in the brain. In arguing for the counter-intuitive epiphenomenal perspective, we suggest that a scientific approach considers all mental aspects of mind including consciousness in terms of their underlying, preceding biological changes, in the realization that most brain processes are not accompanied by any discernible change in subjective awareness.

I show that her argument does not rest solely on color science, but also on a philosophically controversial assumption, namely, that visual states of color supervene on physiological states. However, this assumption, on the part of philosophers or vision scientists, has the effect of simply ruling out certain versions of functionalism. While (...)

I examine a dispute about the nature of practical reason, and in particular moral reason, generated by Thomas Nagel's proposal of an internalist rationalism which claims we can explain motivation in terms of reason and belief alone.

Arguments on either side of this debate typically assume that a rationalist or Humean conclusion can be reached independently of a claim about the nature of moral judgment. I'll maintain, to (...) the contrary, that a resolution of this dispute can only be achieved on the basis of such a claim. (shrink)
