An interview with Ed Casey where we discuss the intersections of his philosophical work with current political issues, including the Israel-Palestine conflict.

The essay brings a summation of human efforts seeking to understand our existence. Plato and Kant & cognitive science complete reduction of philosophy to a neural mechanism, evolved along elementary Darwinian principles. Plato in his famous Cave Allegory explains that between reality and our experience of it there exists a great chasm, a metaphysical gap, fully confirmed through particle-wave duality of quantum physics. Kant found that we have two kinds of perception, two senses: By the spatial outer sense we perceive (...) phenomena, objects in space. Our temporal inner sense lets us perceive our inner state, noumena . Kant's two senses are fully confirmed through bilateral brain duality of cognitive science. The bilateral brain serves inner, temporal sense, logic & noumena in the left hemisphere. The right brain half is for the outer, spatial sense, geometry & phenomena. We form a whole system, a bilateral interior cosmos, a kind of world model, expressing what may lie beyond the metaphysical gap. In the right brain we build a phenomenal cosmos, to resemble the outer environment. In the brain's left hemisphere a noumenal cosmos, a model of our private world including Saint Teresa of Avila's castillo interior. The cosmos is regularly updated with novel sense data integrated into our memory banks. This was recognized early by Helmholtz (1860s). Our lives, health & well-being depend on us keeping our interior cosmos in good order. This used to be seen as saving one's precious soul from perdition. While we endeavour to keep our phenomenal cosmos neat & orderly by protecting the environment from harm, our noumenal cosmos to be livable requires us to engage in ethical conduct. This bilateral cosmos is responsible for our common sense judgment power, that we depend on for being able to lead a good & benign life. The 200 million neurons of BA10 in the prefrontal lobe have global access to the interior cosmos, & apply massive feedback to identify environmental conditions rapidly. The global access also gives conscious presence of the individual to itself, all that is present in the interior cosmos, for total freedom of action. In the left brain private ego, we are guarded by faith in divine mercy, & guided to choose the best course of action, able to survive under the most adverse conditions. For this, we receive directions from the Holy Ghost in Saint Teresa's castillo interior. (shrink)

This paper identifies three positions on the relationship between language and experience, the third of which I was not acquainted with before from my reading. It seems absurd.

Conscious existence is the product of a neural brain mechanism, which is largely identical with Immanuel Kant's Oneness Function, a service performed by 200 million neurons in the prefrontal lobe, & makes possible our interior cosmos, the record of our interconnected, or general, experience. Essential for us humans is the well-being of our interior cosmos, or Saint Teresa of Avila's interior castle, in all interactions with each other \& the greater environment. Any disorders of our cosmos are liable to make (...) us fall ill, setting our existence on a path of psychosomatic etiology of a large class of mysterious undiagnosed diseases. (shrink)

Recent advances in neuroscience lead to a wider realm for philosophy to include the science of the Darwinian-evolved computational brain, our inner world producing organ, a non-recursive super- Turing machine combining 100B synapsing-neuron DNA-computers based on the genetic code. The whole system is a logos machine offering a world map for global context, essential for our intentional grasp of opportunities. We start from the observable contrast between the chaotic universe vs. our orderly inner world, the noumenal cosmos. So far, philosophy (...) has been rehearsing our thoughts, our human-internal world, a grand painting of the outer world, how we comprehend subjectively our experience, worked up by the logos machine, but now we seek a wider horizon, how humans understand the world thanks to Darwinian evolution to adapt in response to the metaphysical gap, the chasm between the human animal and its environment, shaping the organism so it can deal with its variable world. This new horizon embraces global context coded in neural structures that support the noumenal cosmos, our inner mental world, for us as denizens of the outer environment. Kant’s inner and outer senses are fundamental ingredients of scientific philosophy. Several sections devoted to Heidegger, his lizard debunked, but his version of the metaphysical gap & his doctrine of the logos praised. Rorty and others of the behaviorist school discussed also.

Possible worlds models of belief have difficulties accounting for unawareness, the inability to entertain (and hence believe) certain propositions. Accommodating unawareness is important for adequately modelling epistemic states, and representing the informational content to which agents have in principle access given their explicit beliefs. In this paper, I develop a model of explicit belief, awareness, and informational content, along with an sound and complete axiomatisation. I furthermore defend the model against the seminal impossibility result of Dekel, Lipman and Rustichini, according (...) to which three intuitive conditions preclude non-trivial unawareness on any possible worlds model of belief.

From the earliest times, American ethics, the rules for the moral \& intellectual life of the West, used to be founded upon the two principles of self-reliance and good neighborliness. Here we consider the underlying functions of neural brain circuits, organic structures that have evolved adaptively by Darwinian rules subject to selection pressure. In the left brain resides our self-reliant private Ego, making plans, launching initiatives. Your public Ego dwells in the right brain, looking around, meeting with your friendly neighbor. (...) A main component is our bilateral interior cosmos, providing us with all the detailed information about our environment as well as the universe at large. (shrink)

Origin of the Yellowstone hotspot & Columbia River Basalts has remained uncertain until now. Here, we present evidence of meteorite impact origin. The hotspot is shallow, only 200 km deep, invalidating a theory of mantle plume origin. The hotspot track runs from the Yellowstone National Park in NW Wyoming to the volcanic Modoc Plateau in NE California. We present evidence of apparent remnants of an impact crater existing in the Modoc, a large multi-ring structure at least 160 km diameter. Much (...) of the complex crater has become obliterated by later Cascadia and Sierra orogenies. The crater has a tall 4,100 foot central uplift cone, locally known as Chalk Mountain, consisting of diatomaceous earth, presumably the rebound cone of a meteorite impact. This falsifies a theoretical prohibition of cosmic impact volcanism. Based on recent insights into explosive volcanism a plausible mechanism is proposed for how meteorite impacts can lead to resurgent calderas of the Yellowstone type, & of apparent LIP origin from thin crust ET impacts, invalidating theoretical constructs of mantle plumes. We mention chaotic terrains, including plutons, arising antipodal to impacts. (shrink)

In this essay, our goal is to discover science in Martin Heidegger's Introduction to Metaphysics, lecture notes for his 1935 summer semester course, because, after all, his subject is metaphysica generalis, or ontology, and this could be construed as a theory of the human brain. Here, by means of verbatim quotes from his text, we attempt to show that indeed these lectures can be viewed as suggestion for an objective scientific theory of human perception, the human capacity for deciphering phenomena, (...) ie. hermeneutics in its broadest sense. His added notes from the 1953 edition, all of which are comments, not corrections, imply that he never abandoned these thoughts on metaphysics, despite all of his utterances about a need to overcome it, and their popular interpretations to that effect. In his presentation, he further develops the colorful and intuitive style, an hermeneutic language, that he had created in his earlier work Being and Time. Of human existence he speaks in such expressions as being-there -- ``Dasein" -- and being-in-the-world, the latter term no longer explicit in the 1935 lectures. The lectures can be read as a pre-scientific analysis of how man, being-there, perceives his environment, artfully managing to deal with the manifold challenges posed by the phenomenal structures of the universe. Man attentively recognizes and deciphers their pre-linguistic contents and, while trying to make sense of it all, puts into words his awareness. There are numerous passages in Heidegger's work where he in fairly concrete terms provides us with hints for a perceptive science that, as it turns out and is demonstrated below in this essay, can be explained in terms of recent advances in neuroscience. It would be implausible, even unthinkable, unimaginable, for there not to be found essential agreement between on one hand his philosophical insights gained by hermeneutics of Dasein, into how our brain functions to let us know what's happening & on the other hand, scientific discoveries obtained through anatomy, EEG, fMRI, TMS, electrode implants, etc, of brain structures & functions employed in perception of the momentary scene. A nexus between science and philosophy is provided in Heidegger's definitive treatment of the Logos, here interpreted as a structural version of Platonic forms (Burchard, 2014). This allows for neurolinguistic brain functions to serve as meta-context for Heidegger's being-in-the-world. The logical functions of Dasein's anatomical brain are performed by the logos machine, formerly the human soul, using top-down processing based on a global context, the noumenal cosmos which humans maintain internally. Heidegger's 1942/43 winter semester lectures Parmenides extend in unbroken fashion his 1935 work, proving that he never abandoned, as is widely claimed, his metaphysical avenue of thought. (shrink)

Guided by key insights of the four great philosophers mentioned in the title, here, in review of and expanding on our earlier work (Burchard, 2005, 2011), we present an exposition of the role played by language, & in the broader sense, λογοζ, the Logos, in how the CNS, the brain, is running the human being. Evolution by neural Darwinism has been forcing the linguistic nature of mind, enabling it to overcome & exploit the cognitive gap between an animal and its (...) world by recognizing environmental structures. Our work was greatly influenced by Heidegger’s lecture notes on metaphysics (Heidegger, 1935). We found agreement with recent progress in neuroscience, but also mathematical foundations of language theory, equating Logos with the mathematical concept of structure. The mystery of perception across the gap is analyzed as radiation and molecules impinging on sensory neurons that carry linguistic information about gross environmental structures, and only remotely about the physical reality of elementary particles. The most important logical brain function is Ego or Self, guiding the workings of the brain as a logos machine. Ego or Self operates from neurons in frontopolar cortex with global receptive fields. The logos machine can function only by availing itself of global context, its internally stored noumenal cosmos NK, and the categorical-conceptual apparatus CCA, updated continually through the neural default mode network (Raichle, 2005). In the Transcendental Deduction, Immanuel Kant discovered that Ego or Self is responsible for conscious control in perception relying on concepts & categories for a fitting percept to be incorporated intoNK. The entire CNS runs as a “movie-in-the-brain” (Parvizi & Damasio, 2001), at peak speed processing simultaneously in a series of cortical centers a stack of up to twelve frames in gamma rhythm of 25 ms intervals. We equate global context, or NK, with our human world, Heidegger’s Dasein being-in-the-world, and are able to demonstrate that the great philosopher in EM parallels neuro-science concerning the human mind.

Georg Cantor's absolute infinity, the paradoxical Burali-Forti class Ω of all ordinals, is a monstrous non-entity for which being called a "class" is an undeserved dignity. This must be the ultimate vexation for mathematical philosophers who hold on to some residual sense of realism in set theory. By careful use of Ω, we can rescue Georg Cantor's 1899 "proof" sketch of the Well-Ordering Theorem––being generous, considering his declining health. We take the contrapositive of Cantor's suggestion and add Zermelo's choice function. (...) This results in a concise and uncomplicated proof of the Well-Ordering Theorem. (shrink)

Perceptual experience is often said to be transparent; that is, when we have a perceptual experience we seem to be aware of properties of the objects around us, and never seem to be aware of properties of the experience itself. This is a introspective fact. It is also often said that we can infer a metaphysical fact from this introspective fact, e.g. a fact about the nature of perceptual experience. A transparency theory fills in the details for these two facts, (...) and bridges the gap between them. We have three aims: to scrutinize Michael Tye’s transparency theory :137–151, 2002; Consciousness revisited: materialism without phenomenal concepts, MIT Press, Cambridge, 2009; Philos Stud 170:39–57, 2014a), introduce a new transparency theory, and advance a meta-theoretical hypothesis about the interest, and import, of transparency theories.

It is observed that most development modalities employed over the years for achieving community development in Africa have not leaved up to expectation in terms of involving the majority of people in the quest for national transformation and development; rather, these modalities tend to complicate the very problems they are set out to solve. The situation is mostly like this because the adopted development strategies have not taken adequate cognizance the essence of effective communication methods and the importance of people’s (...) perspectives and peculiarities in these processes. Mostly, the so-called outsiders and experts in development matters who are physically and socially separated from the people think for them and about their development. This situation is inimical to genuine and sustainable development. It is important therefore to note that development can only be meaningful and sustainable when it is people generated; involving people’s real needs and their participation in the process of achieving them. It is at this point therefore that community theatre can come handy as it has the potentials to bring people together to discuss issues that disempowered them and participatorily proffer solutions to the negatives. Community theatre can be explored to work with rural and urban people; mostly the rural dwellers who are mostly disempowered. In view of this therefore, this paper posits that community theatre is a method of participatory communication towards achieving social change. (shrink)

Jeanette Edwards observes a pattern of questions of the form “Why do anthropology fieldwork in location X?” - she only hears the question posed of some places - and she explains this pattern by saying that some places are taken to be obviously legitimate for anthropology fieldwork whereas others are not. I draw distinctions between legitimate and illegitimate, obviously legitimate and not obviously legitimate, and better and worse. The distinctions lead to a different explanation.

In his Edifying Discourses, Soren Kierkegaard published a sermon entitled ‘The Unchangeableness of God’ in which he reiterated the dogma which dominated Catholic, Protestant and even Jewish expressions of classical supernaturalist theology from the first century A.D. until the advent of process theology in the twentieth century. The dogma that as a perfect being, God must be totally unchanging in every conceivable respect was expressed by Kierkegaard in such ways as: He changes all, Himself unchanged. When everything seems stable and (...) in the overturn of all things, He remains equally unchanged; no change touches Him, not even the shadow of a change; in unaltered clearness He, the father of lights, remained eternally unchanged. 1.

In this paper I make some distinctions, which I hope are of help for Laura Valentini and others. Are the recommendations of a theory of what the government should do possible and are they feasible? Is the project of the theorist possibility-sensitive and is the project feasibility-sensitive?

Imprecise probabilities are often modelled with representors, or sets of probability functions. In the recent literature, two ways of interpreting representors have emerged as especially prominent: vagueness interpretations, according to which each probability function in the set represents how the agent's beliefs would be if any vagueness were precisified away; and comparativist interpretations, according to which the set represents those comparative confidence relations that are common to all probability functions therein. I argue that these interpretations have some important limitations. I (...) also propose an alternative—the functional interpretation—according to which representors are best interpreted by reference to the roles they play in the theories that make use of them.

This essay examines Hobbes’ philosophy of space, with emphasis placed on the variety of interpretations that his concept of imaginary space has elicited from commentators. The process by which the idea of space is acquired from experience, as well as the role of nominalism, will be offered as important factors in tracking down the elusive content of Hobbes’ conception of imaginary space.

Moral naturalists are often said to have trouble making sense of inter-communal moral disagreements. The culprit is typically thought to be the naturalist’s metasemantics and its implications for the sameness of meaning across communities. The most familiar incarnation of this metasemantic challenge is the Moral Twin Earth argument. We address the challenge from the perspective of analytic naturalism and argue that making sense of inter-communal moral disagreement creates no special issues for this view.

Studie se zabývá tím, jak se v českých zemích obráželo bouřlivé období vývoje biologického myšlení od přelomu 19. a 20. století do první světové války, kdy vedle sebe existovaly velmi různé názory na evoluci. Mnohovrstevnatost teoretickou přitom doplňuje i kulturní a vědecká mnohovrstevnatost českých zemí, kde se jednak mísí vlivy německé a české biologie na svých autonomních institucích, a jednak lze spatřovat rozdíly i mezi lokálními centry Prahou a Brnem se svými badatelskými tradicemi a nezávislými vazbami na další centra ve (...) Vídni a evropských univerzitách. Centrem zájmu jsou teoreticky uvažující biologové, kteří buď sami dlouhodobě profilovali české biologické myšlení, anebo na něj měli díky zdejšímu působení přímý vliv. V letech ca 1900–1915 došlo k prvnímu otevřenému a diskutovanému vrcholu v české recepci evolucionismu a před jednoznačnými pozicemi a „velkými teoriemi“ má navrch spíše prostředkování diferencované zahraniční diskuse, podněty vlastní experimentální práce a opatrné očekávání od nového studia variability a dědičnosti.

Among the most popular strategies for justifying political obligations are those that appeal to the principle of fairness. These theories face the challenge, canonically articulated by Robert Nozick, of explaining how it is that persons are obligated to schemes when they receive goods that they do not ask for but cannot reject. John Simmons offers one defense of the principle of fairness, arguing that people could be bound by obligations of fairness if they voluntarily accept goods produced by a cooperative (...) scheme. Simmons, however, thinks that such a theory will do little work in justifying political obligations, since virtually no one voluntarily accepts state goods. This paper attempts to advance just such a theory by arguing that states are in fact genuine cooperative schemes and that Simmons is overly pessimistic in his appraisal of whether the majority of citizens accept the goods provided by their states.

Apparently the Western philosophical tradition has (wrongly) preferred speech over writing – so claims Jacques Derrida. In this paper, I consider whether utilitarianism involves such a preference. There are at least two arguments against the claim.

This paper examines Descartes' problematic relational theory of motion, especially when viewed within the context of his dynamics, the Cartesian natural laws. The work of various commentators on Cartesian motion is also surveyed, with particular emphasis placed upon the recent important texts of Garber and Des Chene. In contrast to the methodology of most previous interpretations, however, this essay employs a modern "spacetime" approach to the problem. By this means, the role of dynamics in Descartes' theory, which has often been (...) neglected in favor of kinematic factors, is shown to be central to finding a solution to the puzzle of Cartesian motion.

This document gathers together, in summary form, objections scattered across many papers and multiple online databases. Nevertheless, it omits some objections, notably complicated ones.

This paper argues for the value of philosophers in a school of social sciences within a university, for fixing what I call disciplinary constitutions. A disciplinary constitution is a statement of “How our discipline works: how we achieve the ends of our discipline.” A lot of people depend on a constitution, but such a thing usually runs into problems and philosophers can identify these problems and propose solutions. I suggest that it is essential for the autonomy of an ambitious school (...) to be able to do such work internally. (shrink)

This paper provides an exposition and defence of Lewis' theory of radical interpretation. The first part explains what Lewis' theory was; the second part explains what it wasn't, and in so doing addresses a number of common objections that arise as a result of widespread myths and misunderstandings about how Lewis' theory is supposed to work.

This essay explores the possibility of constructing a structural realist interpretation of spacetime theories that can resolve the ontological debate between substantivalists and relationists. Drawing on various structuralist approaches in the philosophy of mathematics, as well as on the theoretical complexities of general relativity, our investigation will reveal that a structuralist approach can be beneficial to the spacetime theorist as a means of deflating some of the ontological disputes regarding similarly structured spacetimes.

This document briefly summarizes several objections to Thomas Kuhn on science, including by Feyerabend, Davidson, and Fodor.

This is a one page handout reconstructing the paradox and identifying four solutions in the literature, as well as some concerns about them.

This paper offers a cheap solution to Laura Valentini’s paradox of ideal theory. An ideal theory cannot be sound by definition, since in the relevant sense of “ideal theory” it involves false propositions.

I present a sense of the term “ideal theory” based on Joseph Raz’s response to the situation of a lifeguard faced with three drowning on one side and two on the other and unable to save all. From what is of value, such a theory builds up a conception of an ideal political state or an aspect of it which we have reason to realize, but ignoring whether it is possible for us to realize this.

Is autonomy – governing yourself – compatible with letting yourself be governed by trust? This paper argues that autonomy is not only compatible with appropriate trust but actually requires it. Autonomy requires appropriate trust because it is undermined by inappropriate mistrust. An autonomous agent treats herself as answerable for her action-guiding commitments, where answerability requires openness to the rational influence of external, critical perspectives on those commitments. This openness to correction makes one vulnerable to manipulation and can be exploited in (...) ways that undermine autonomy instead of supporting it. We argue that autonomy is undermined by inappropriate trust, and that the inappropriateness lies in the agent’s failure to manifest appropriate responsiveness to evidence of untrustworthiness in the one trusted. The problem isn’t that autonomy requires dispensing with trust but that trust must itself be governed by appropriate responsiveness to evidence of untrustworthiness. Our view confronts two challenges. One challenge lies in explaining why you shouldn’t treat your vulnerability to manipulation as a general reason to let your trusting disposition lapse into an untrusting one. We argue that there is no such general reason to let your responsiveness to evidence of untrustworthiness be supplanted by a suspicious disposition to seek and require positive evidence of trustworthiness. A second, and deeper, challenge arises from the fact that in some especially sophisticated cases of manipulation there is no evidence of untrustworthiness to which you could respond. We argue that you cannot rationally cope with even this unresolvable risk of exploited trust by trusting only yourself. (shrink)

If by “demon” one understands an evil occult being, then its equivalent in the Islamic narrative is the intersection of the category jinn with that of the shayātīn: a demon is a shaytān from among the jinn. The literature in the Islamic tradition on these subjects is vast. In what follows, we will select some key elements from it to provide a brief summary: first on the nature of the jinn, their nature, and their relationship to God and human beings; (...) second, on the origin, nature, and role of Shaytān (Satan himself) and the shayātīn in the moral drama of Islam. Then, we will take a closer look at the relationship between jinn and humankind, according to Islam, and the phenomena of the demonic as it manifests itself in that relation. In the process, I will entertain, tentatively, some philosophical speculation as to the nature of that ultimately mysterious relation and phenomena, drawn from what we find in the religious sources.

[The version of this paper published by Oxford online in 2019 was not copy-edited and has some sense-obscuring typos. I have posted a corrected (but not the final published) version on this site. The version published in print in 2020 has these corrections.] Which is more fundamental, assertion or testimony? Should we understand assertion as basic, treating testimony as what you get when you add an interpersonal addressee? Or should we understand testimony as basic, treating mere assertion -- assertion without (...) testimony -- as what you get when you subtract that interpersonal relation? In this chapter, I’ll argue for the subtractive approach and for the more general thesis that its treatment of the interpersonal element in assertion makes understanding that interpersonal element the key to understanding how assertion expresses belief. My theory of belief-expression in assertion treats it as internalizing the transmission of belief in testimony. How we understand that internalizing move depends on how we conceptualize the interpersonal element in testimony. Since what I’ll call the Command Model does not give us the conceptual resources to make this move, we should adopt an alternative that I’ll call the Custodial Model, on which a testifier aims not to convince her addressee but to reason with him – to give him reasons to believe what she tells him grounded in her trustworthiness in thus attempting to influence him. The subtractive approach to assertion thus rests on a key distinction between the aims of reasoning and persuasion. (shrink)

Very little attention has been paid towards examining John Rawls’s liberal principle of legitimacy as a self-standing theory. Nevertheless, it offers a highly original way of thinking about state legitimacy. In this paper, I will offer a sketch of what such an account might look like. At its heart is the idea that the legitimacy of the state resides not in the consent of the governed, nor in the state’s conformity with the appropriate principles of justice, but rather in citizens’ (...) endorsement of the state and its underlying constitutional principles on the basis of their own comprehensive conceptions of justice. Such an account offers a stable middle ground between popular alternatives, and has a way of not just solving, but dissolving, the problem of legitimacy. (shrink)

Plotinus’ famous treatise against the Gnostics (33), together with contemporary and thematically related treatises on Intelligible Beauty (31), on Number (34), and on Free Will and the Will of the One (39), can be seen as providing the essential components of a Plotinian defense of polytheism against conceptual moves that, while associated for him primarily with Gnostic sectarians overlapping with Platonic philosophical circles, will become typical of monotheism in its era of hegemony. When Plotinus’ Gnostics ‘contract’ divinity into a single (...) God, they not only devalue the cosmos for its multiplicity and diversity, but also multiply intelligible principles unreasonably. This is because they have foreclosed the distinction, which is to become increasingly explicit in the later antique Platonists, between the intelligible and that which is given existentially, the domain belonging to Plotinus’ indeterminate multiplicity of ‘intelligible Gods’, as opposed to the dialectically determinate number of intelligible principles. Plotinus is prescient in recognizing that incipient monotheism threatens to erase the distinction between philosophy and theology, and between both of these and psychology, the final outcome of which can only be solipsism or nihilism. The defense of polytheism is seen in this fashion to be essential to the preservation of the space for philosophical discourse. (shrink)

This essay explores the vexed issue of individual corporeal substance in Descartes' natural philosophy. Although Descartes' often referred to individual material objects as separate substances, the constraints on his definitions of matter and substance would seem to favor the opposite view; namely, that there exists only one corporeal substance, the plenum. In contrast to this standard interpretation, however, it will be demonstrated that Descartes' hypotheses make a fairly convincing case for the existence of individual material substances; and the key to (...) this new found individuation is a long neglected set of passages in the Principles of Philosophy.

Jeanette Edwards did fieldwork in the English town of Bacup. Why do fieldwork there? She writes that she is often asked this, whereas the question is unlikely to be asked of an anthropologist who does fieldwork in Papua New Guinea, because it is “axiomatically” an acceptable place for fieldwork. I present two responses to Edwards’ thinking, one of which concerns an asymmetry in how “skeptics” present their questions.

Why do a conceptual analysis on a word that we already know how to use? Marilyn Strathern provides some information on garden cities and suburbs which suggests a novel solution to me.

Jeanette Edwards tells us that she is often asked about why she did fieldwork in the English town of Bacup, whereas she has not heard anthropologists who did fieldwork in Papua New Guinea asked why there. She commits herself to a certain explanation for this: potential inquirers assume that non-Western societies are legitimate objects of study for social anthropology but this is not assumed for Western societies. I propose another explanation: it is not about the legitimacy of the object of (...) study, rather “your” levels of commitment. Would you do that for anthropology? (shrink)

This article investigates the problem of the identity of the parts of space in Newton’s natural philosophy, as well as the holistic or structuralist nature of Newton’s ontology of space. Additionally, this article relates the lessons reached in this historical and philosophical investigation to analogous debates in contemporary space-time ontology. While previous contributions, by Nerlich, Huggett, and others, have proven to be informative in evaluating Newton’s claims, it will be argued that the underlying goals of Newton’s views have largely eluded (...) prior analysis and that Newton’s approach is similar, and lends support, to several current structuralist trends in the conception of space-time ontology.

This paper investigates the question of, and the degree to which, Newton’s theory of space constitutes a third-way between the traditional substantivalist and relationist ontologies, i.e., that Newton judged that space is neither a type of substance/entity nor purely a relation among such substances. A non-substantivalist reading of Newton has been famously defended by Howard Stein, among others; but, as will be demonstrated, these claims are problematic on various grounds, especially as regards Newton’s alleged rejection of the traditional substance/accident dichotomy (...) concerning space. Nevertheless, our analysis of the metaphysical foundations of Newton’s spatial theory will strive to uncover its unique and innovative characteristics, most notably, the distinctive role that Newton’s “immaterialist” spatial ontology plays in his dynamics.

Jeanette Edwards sounds as if she wishes to reject the question “Why did you do fieldwork there?” I propose a metaphysical route to this, which is to say, “The self before fieldwork is not my self,” but this conflicts with the traditional Lockean account of personal identity.

Joseph Raz criticizes John Rawls for a procedure supporting a non-adaptable constitution. This paper considers how a non-adaptable constitution can seem not so counterintuitive and also when.

This paper investigates Newton’s ontology of space in order to determine its commitment, if any, to both Cambridge neo-Platonism, which posits an incorporeal basis for space, and substantivalism, which regards space as a form of substance or entity. A non-substantivalist interpretation of Newton’s theory has been famously championed by Howard Stein and Robert DiSalle, among others, while both Stein and the early work of J. E. McGuire have downplayed the influence of Cambridge neo-Platonism on various aspects of Newton’s own spatial (...) hypotheses. Both of these assertions will be shown to be problematic on various grounds, with special emphasis placed on Stein’s influential case for a non-substantivalist reading. Our analysis will strive, nonetheless, to reveal the unique or forward-looking aspects of Newton’s approach, most notably, his critical assessment of substance ontologies, that help to distinguish his theory of space from his neo-Platonic contemporaries and predecessors.

An assurance theory of trust begins from the act of assurance – whether testimonial, advisorial or promissory – and explains trust as a cognate stance of resting assured. My version emphasizes the risks and rewards of trust. On trust’s rewards, I show how an assurance can give a reason to the addressee through a twofold exercise of ‘normative powers’: (i) the speaker thereby incurs an obligation to be sincere; (ii) if the speaker is trustworthy, she thereby gives her addressee the (...) reason. Each claim is controversial; my contribution lies in how I defend them together, linking the sincerity obligation to the provision of reasons. On trust’s risks, I defend a popular thesis about the nature of trust – that trust differs from mere reliance in how it risks betrayal – against the objection that the thesis ‘moralizes’ trust. Such betrayal need not be moral, I argue, because it may derive entirely from how the assurance purports to provide a reason. (shrink)

This is a sketch of the basis and role of consciousness and the minimally required elements and constraints of any setting that may produce consciousness. It proposes that consciousness (as we know it) is a biologically-mediated product of evolved recursive and hierarchically nested representational systems that obey information theoretic principles and Bayesian (probabilistic) feedback and feedforward predictive modeling processes.
