The theory of lower previsions is designed around the principles of coherence and sure-loss avoidance, thus steers clear of all the updating anomalies highlighted in Gong and Meng's "Judicious Judgment Meets Unsettling Updating: Dilation, Sure Loss, and Simpson's Paradox" except dilation. In fact, the traditional problem with the theory of imprecise probability is that coherent inference is too complicated rather than unsettling. Progress has been made simplifying coherent inference by demoting sets of probabilities from fundamental building blocks to secondary representations (...) that are derived or discarded as needed.

Coherentism maintains that coherent beliefs are more likely to be true than incoherent beliefs, and that coherent evidence provides more confirmation of a hypothesis when the evidence is made coherent by the explanation provided by that hypothesis. Although probabilistic models of credence ought to be well-suited to justifying such claims, negative results from Bayesian epistemology have suggested otherwise. In this essay we argue that the connection between coherence and confirmation should be understood as a relation mediated by the causal relationships (...) among the evidence and a hypothesis, and we offer a framework for doing so by fitting together probabilistic models of coherence, confirmation, and causation. We show that the causal structure among the evidence and hypothesis is sometimes enough to determine whether the coherence of the evidence boosts confirmation of the hypothesis, makes no difference to it, or even reduces it. We also show that, ceteris paribus, it is not the coherence of the evidence that boosts confirmation, but rather the ratio of the coherence of the evidence to the coherence of the evidence conditional on a hypothesis.

Analyzing geometric properties of high-dimensional loss functions, such as local curvature and the existence of other optima around a certain point in loss space, can help provide a better understanding of the interplay between neural network structure, implementation attributes, and learning performance. In this work, we combine concepts from high-dimensional probability and differential geometry to study how curvature properties in lower-dimensional loss representations depend on those in the original loss space. We show that saddle points in the original space are (...) rarely correctly identified as such in expected lower-dimensional representations if random projections are used. The principal curvature in the expected lower-dimensional representation is proportional to the mean curvature in the original loss space. Hence, the mean curvature in the original loss space determines if saddle points appear, on average, as either minima, maxima, or almost flat regions. We use the connection between expected curvature in random projections and mean curvature in the original space (i.e., the normalized Hessian trace) to compute Hutchinson-type trace estimates without calculating Hessian-vector products as in the original Hutchinson method. Because random projections are not suitable to correctly identify saddle information, we propose to study projections along dominant Hessian directions that are associated with the largest and smallest principal curvatures. We connect our findings to the ongoing debate on loss landscape flatness and generalizability. Finally, for different common image classifiers and a function approximator, we show and compare random and Hessian projections of loss landscapes with up to about 7×10^6 parameters. (shrink)

The field of of imprecise probability has matured, in no small part because of Teddy Seidenfeld’s decades of original scholarship and essential contributions to building and sustaining the ISIPTA community. Although the basic idea behind imprecise probability is (at least) 150 years old, a mature mathematical theory has only taken full form in the last 30 years. Interest in imprecise probability during this period has also grown, but many of the ideas that the mature theory serves can be difficult to (...) apprehend to those new to the subject. Although these fundamental ideas are common knowledge in the ISIPTA community, they are expressed, when they are expressed at all, obliquely, over the course of years with students and colleagues. -/- A single essay cannot convey the store of common knowledge from any research community, let alone the ISIPTA community. But, this essay nevertheless is an attempt to guide those familiar with the basic Bayesian framework to appreciate some of the elegant and powerful ideas that underpin the contemporary theory of lower previsions, which is the theory that most people associate with the term ‘imprecise probabilities’.

Recent debate about the error theory has taken a ‘formal turn’. On the one hand, there are those who argue that the error theory should be rejected because of its difficulties in providing a convincing formal account of the logic and semantics of moral claims. On the other hand, there are those who claim that such formal objections fail, maintaining that arguments against the error theory must be of a substantive rather than a formal kind. In this paper, we argue (...) that formal objections to the error theory cannot be eschewed but must be met head-on. (shrink)

Dilation occurs when an interval probability estimate of some event E is properly included in the interval probability estimate of E conditional on every event F of some partition, which means that one’s initial estimate of E becomes less precise no matter how an experiment turns out. Critics maintain that dilation is a pathological feature of imprecise probability models, while others have thought the problem is with Bayesian updating. However, two points are often overlooked: (1) knowing that E is stochastically (...) independent of F (for all F in a partition of the underlying state space) is sufficient to avoid dilation, but (2) stochastic independence is not the only independence concept at play within imprecise probability models. In this paper we give a simple characterization of dilation formulated in terms of deviation from stochastic independence, propose a measure of dilation, and distinguish between proper and improper dilation. Through this we revisit the most sensational examples of dilation, which play up independence between dilator and dilatee, and find the sensationalism undermined by either fallacious reasoning with imprecise probabilities or improperly constructed imprecise probability models.

Jim Joyce argues for two amendments to probabilism. The first is the doctrine that credences are rational, or not, in virtue of their accuracy or “closeness to the truth” (1998). The second is a shift from a numerically precise model of belief to an imprecise model represented by a set of probability functions (2010). We argue that both amendments cannot be satisfied simultaneously. To do so, we employ a (slightly-generalized) impossibility theorem of Seidenfeld, Schervish, and Kadane (2012), who show that (...) there is no strictly proper scoring rule for imprecise probabilities. -/- The question then is what should give way. Joyce, who is well aware of this no-go result, thinks that a quantifiability constraint on epistemic accuracy should be relaxed to accommodate imprecision. We argue instead that another Joycean assumption — called strict immodesty— should be rejected, and we prove a representation theorem that characterizes all “mildly” immodest measures of inaccuracy.

The desirable gambles framework offers the most comprehensive foundations for the theory of lower pre- visions, which in turn affords the most general ac- count of imprecise probabilities. Nevertheless, for all its generality, the theory of lower previsions rests on the notion of linear utility. This commitment to linearity is clearest in the coherence axioms for sets of desirable gambles. This paper considers two routes to relaxing this commitment. The first preserves the additive structure of the desirable gambles framework and (...) the machinery for coherent inference but detaches the interpretation of desirability from the multiplicative scale invariance axiom. The second strays from the additive combination axiom to accommodate repeated gambles that return rewards by a non-stationary processes that is not necessarily additive. Unlike the first approach, which is a conservative amendment to the desirable gambles framework, the second is a rad- ical departure. Yet, common to both is a method for describing rewards called discounted utility. (shrink)

A characterization result of dilation in terms of positive and negative association admits an extremal counterexample, which we present together with a minor repair of the result. Dilation may be asymmetric whereas covariation itself is symmetric. Dilation is still characterized in terms of positive and negative covariation, however, once the event to be dilated has been specified.

Epistemic decision theory (EDT) employs the mathematical tools of rational choice theory to justify epistemic norms, including probabilism, conditionalization, and the Principal Principle, among others. Practitioners of EDT endorse two theses: (1) epistemic value is distinct from subjective preference, and (2) belief and epistemic value can be numerically quantified. We argue the first thesis, which we call epistemic puritanism, undermines the second.

Information-based epistemology maintains that ‘being informed’ is an independent cognitive state that cannot be reduced to knowledge or to belief, and the modal logic KTB has been proposed as a model. But what distinguishes the KTB analysis of ‘being informed’, the Brouwersche schema (B), is precisely its downfall, for no logic of information should include (B) and, more generally, no epistemic logic should include (B), either.

The purpose of this paper is to show that if one adopts conditional probabilities as the primitive concept of probability, one must deal with the fact that even in very ordinary circumstances at least some probability values may be imprecise, and that some probability questions may fail to have numerically precise answers.

A sound and complete axiomatization of two tabloid blogs is presented, Leiter Logic (KB) and Deontic Leiter Logic (KDB), the latter of which can be extended to Shame Game Logic for multiple agents. The (B) schema describes the mechanism behind this class of tabloids, and illustrates the perils of interpreting a provability operator as an epistemic modal. To mark this difference, and to avoid sullying Brouwer's good name, the (B) schema for epistemic modals should be called the Blog Schema.

Traditionally, logic has been the dominant formal method within philosophy. Are logical methods still dominant today, or have the types of formal methods used in philosophy changed in recent times? To address this question, we coded a sample of philosophy papers from the late 2000s and from the late 2010s for the formal methods they used. The results indicate that the proportion of papers using logical methods remained more or less constant over that time period but the proportion of papers (...) using probabilistic methods was approximately three times higher in the late 2010s than it was in the late 2000s. Further analyses explored this change by looking more closely at specific methods, specific levels of technical engagement, and specific subdisciplines within philosophy. These analyses indicate that the increasing proportion of papers using probabilistic methods was pervasive, not confined to particular probabilistic methods, levels of sophistication, or subdisciplines.

This chapter is a work in applied metaphysics. Recent discussions of monism and metaphysical dependence are deployed to develop a view—the doctrine of divine priority (DDP)—that is a viable alternative to the doctrine of divine simplicity (DDS). DDS and the traditional motivation for it are discussed, then DDP is introduced by way of an analogy involving Jonathan Schaffer’s distinction between two forms of monism. It is argued that DDP is an alternative to DDS by showing that it is consistent with (...) the traditional motivation for the latter view, and argued that DDP is a viable alternative by showing that objections to its peculiar implications rest on assumptions that can reasonably be rejected. In the concluding section, the findings of the main discussion are summarized and DDP’s potential theological import is illustrated with a brief discussion of a possible solution to the Problem of the Trinity it affords.

This unpublished paper, which readers should feel free to cite, is posted primarily for the historical record. In recent work that has, deservedly, received some attention, Paul R. Daniels presents and defends a non-standard theory of persistence that he dubs transdurantism, according to which persisting objects are temporally extended simples. This is exactly what I do in work dating back to 2004. (This work began with an earlier draft of this paper, which was presented to the University of Rochester's Philosophy (...) Department in 2005, and culminated in this version, which I believe dates from 2010.) While this might be a total coincidence, I doubt that it is, especially given that 'transdurantism' appears as a name for a theory of persistence associated with me in at least two places in the literature, one of which includes a citation of this paper. The paper begins with a discussion of what I call 'locative relations' (the relations borne by material objects to the regions of space and time they occupy), which draws relevant distinctions that others have failed to draw. The results of this discussion are then used in constructing spatial analogues for the three established theories of persistence--endurantism, perdurantism, and exdurantism--as well as for transdurantism. Next, these four views concerning persistence are explicitly formulated and a defense of their formulation is offered. Finally, transdurantism's advantages and disadvantages relative to the other theories are discussed. The main goal of the paper is to challenge the trichotomy between the established theories by arguing that transdurantism is also a viable view concerning persistence through time. [Note: Befitting its status as a historical document, with the exception of some light editing to fix typos that might impede understanding, no changes have been made to the paper.]. (shrink)

We often ascribe possibility to the scenes that are displayed by mental or nonmental sensory images. The paper presents a novel argument for thinking that we are prima facie justified in ascribing metaphysical possibility to what is displayed by suitable visual images, and it argues that many of our imagery‐based ascriptions of metaphysical possibility are therefore prima facie justified. Some potential objections to the arguments are discussed, and some potential extensions of them, to cover nonvisual forms of imagery and nonmetaphysical (...) forms of possibility, are endorsed.

In The Decline of the West Spengler puts forward a type of philosophical anthropology, an account of the structures of human experiential consciousness and a method of “physiognomic” analysis, which I argue has dimensions that can be understood as akin to existential phenomenology. Humanity, for Spengler, is witness to the creative flux of “Becoming” and constructs a world of phenomena bounded by death, underpinned by the two prime feelings of dread and longing and structured by the two forms of Destiny (...) (Time) and Direction (Space). Human existence, Spengler argues, is future-directed and open in the sense that there is a certain degree of freedom in the ways in which humanity can actualize its existential possibilities. In the course of elaborating the existential implications of this future-orientation, Spengler introduces the concept of care (Sorge), the fundamental experiential structure. (shrink)

Visualizings, the simplest imaginings which employ visual imagery, have certain characteristic features; they are perspectival, for instance. Also, it seems that some but not all of our visualizings are imaginings of seeings. But it has been forcefully argued, for example by M.G.F. Martin and Christopher Peacocke, that all visualizings are imaginings of visual sensations. I block these arguments by providing an account of visualizings which allows for their perspectival nature and other features they typically have, but which also explains how (...) we can visualize things without thereby imagining visual sensations. (shrink)

Why do we tend to ascribe possibility to what we can imagine? One strategy for answering that question involves the thought that, just as sensory episodes often involve its seeming to us as though the world is certain ways, so imaginings involve its seeming to us that what we have imagined is possible. This chapter argues that while some imaginings do feature appearances of possibility, very many others do not; and it explores the broader relevance of its conclusions for modal (...) epistemology.

I argue that identifying the person with the brain is scientism (not science), that the brain is not the person, and that it is the person who learns. In fact the brain only responds to the learning of embodied experience within the extra-neural network of intersubjective communications. Learning is a dynamic, cultural activity, not a neural program. Brain-based learning is unnecessary for educators and may be dangerous in that a culturally narrow ontology is taken for granted, thus restricting our creativity and imagination, and narrowing the human community.

In this condensed survey, I look to recent perspectives on evolution suggesting that cultural change likely alters the genome. Since theories of development are nested within assumptions about evolution (evo-devo), I next review some oft-cited developmental theories and other psychological theories of the 20th century to see if any match the emerging perspectives in evolutionary theory. I seek theories based neither in nature (genetics) nor nurture (the environment) but in the creative play of human communication responding to necessity. This survey (...) finally looks to more recent work to do with the appearance of independent self-consciousness in the individual following empathic group awareness. The result of such self-created group awareness and symbolic communication is seen to be cultural consciousness, unique to humanity, from which individual consciousness and personhood derive. I conclude by noting the general implications for these approaches in our schools, politics, and in ultimate ontological questions. (shrink)

This paper addresses the generally neglected topic of Vandana Shiva’s ontology. It is argued that there is a significant ontological component to Shiva’s ecofeminist philosophy and that this ontology underpins her ecological and feminist views. Shiva’s ontology provides a standpoint from which she can critique dichotomous ontologies of domination and oppression, and from which she can identify life-sustaining modes of existence. It is argued that this ontology is implicit in most of her works and is best grasped through the analysis (...) of her critique of Western scientific metaphysics. It is further argued that this implied ontology is a continuation of the Hindu-ecofeminist ontology of Prakriti explicitly set forth in Shiva’s Staying Alive (1989). Both forms of Shiva’s ontology, the explicit and the implicit, will be reconstructed and their points of continuity detailed. (shrink)

This paper argues that the recent renewal of interest in the philosophy of Oswald Spengler, particularly concerning its warnings of the imminent demise of Western Civilisation, is misplaced. Arguments concerning the accuracy of his predictions or cultural analysis have overlooked the necessity of evaluating the coherence of the philosophical system that Spengler used to generate and justify his speculative declarations. Such an evaluation indicates a number of apparent contradictions at the heart of Spengler’s historical model. The attempt to resolve these (...) contradictions has resulted in a sharp division of interpretation amongst Spengler commentators, into positivist and relativist camps. Neither interpretation, I suggest, is capable of rendering Spengler’s historical system coherent. It is therefore argued that Spengler’s philosophy is fundamentally flawed. (shrink)

Rønnow-Rasmussen’s book explores the distinction between two kinds of value: good, and good-for. Rønnow-Rasmussen provides a reductive theory of both kinds of goodness: a fitting attitude account of goodness, on which facts about value reduce to facts about the norms governing agents’ attitudes. But Rønnow-Rasmussen argues that they conflict in an especially sharp way, so that we have a kind of choice about which to prioritise, and no obvious grounds on which to choose one over the other. I articulate some (...) virtues of the book but also doubts about the central thesis. (shrink)

Oswald Spengler is best known as a philosopher of history. However, one can trace in volume one of his The Decline of the West a sustained consideration of philosophical issues pertaining to the nature and practice of science that I suggest can be considered to be a philosophy of science. Not only has Spengler’s philosophy of science been largely overlooked, so too has its peculiar fictionalist character. By elaborating on the fictionalist character of Spengler’s scientific views I shall consider his (...) work in comparison with that of Hans Vaihinger, a contemporary of Spengler and noted fictionalist with regards to science. This comparison not only supports my interpretation of Spengler’s philosophy of science as fictionalist, it also throws into relief the numerous affinities between the thought of two philosophers who are not usually associated, in particular with regards to their accounts of the origins of science in the structures of human consciousness. This fictionalist affinity in turn suggests the need for a wholesale reappraisal of Spengler’s philosophical outlook. (shrink)

[Pre-peer review draft available to download.] Our imaginative capacities shape the making of images, while the making of images has the ability to shape our imaginative capacities. What are the connections between vision and mental visual images that allow for this traffic between the contents of our minds and external images? And how are image-makers able to exploit the distinctive powers of imagery, to extend the modes of representation that are available to us, and hence also to extend the resources (...) upon which our imaginations can draw? The chapter explores various aspects of those issues. It starts by exploring “visual imagery” as a general category; and it identifies one very striking range of cases that encompasses both suitable mental and nonmental visual images. It develops a philosophical account of what is distinctive about the range of visual images thus identified. Subsequent sections then use the resulting ideas to investigate some of the ways in which various strategies for creating visual images exploit in remarkably inventive ways possibilities that are latent within the general phenomenon of imagistic representation.

This entry discusses the relationship between disability and well‐being. Disabilities are commonly thought to be unfortunate, but whether this is true is unclear, and, if it is true, it is unclear why it is true. The entry first explains the disability paradox, which is the apparent discrepancy between the level of well‐being that disabled people self‐report, and the level of well‐being that nondisabled people predict disabled people to have. It then turns to an argument that says that disabilities must be (...) bad, because it is wrong to cause them in others. Later sections discuss whether disabilities might be intrinsically bad or even bad by definition. The final section addresses the claim that disabilities are bad only because society discriminates against people with disabilities. (shrink)

In the fourth, I look at other texts within the Anselmian corpus, notably the De humanibus moribus and the Dicta Anselmi.

Ecofeminist philosophy is a development of feminist philosophy that addresses the intersection of sexism and environmental issues. Coined by Francoise d’Eaubonne, the term “ecofeminism” refers to a diverse collection of feminist thought that shares the conviction that the present environmental crisis is due not solely to the anthropomorphic nature of dominant conceptualisations of human-nature relations, with their emphasis on notion of mastery and control, but also to their androcentric nature. Technology features frequently in ecofeminist writings, in analyses of technocracy (Birkeland (...) 1993), Nuclear Power (Caputi 1993), reproductive technologies (Diamond 1990), or the production of computer interfaces (Romberger 2011), to give but a few examples. Despite being a recurrent theme, technology itself as a phenomenon is rarely directly considered. For many ecofeminists technology seems to operate as an umbrella term for a collection of artefacts whose positive or negative characteristics are ultimately contingent upon the manner in which they are employed. The individual technologies appear as value neutral. There are of course exceptions to this piecemeal approach to technological artefacts, and in this chapter I shall focus upon two ecofeminist philosophers whose consideration of technology moves from the individual instance towards a more general account of the nature of technology. The first, Karen Warren, gives technology a central place in her philosophical analysis. However, I shall suggest, her commitment to an instrumental understanding of technology renders her approach problematic. I will then consider the work of Vandana Shiva. Standard analyses of Shiva’s work tend to overlook the philosophical dimensions of her thought, in particular the continuous emphasis on science and technology. I argue that Shiva puts forward a sophisticated technological determinist philosophy of that emphasises the role of political and patriarchal interests in technological development and subsequent social and environmental interventions.

Verbal irony constitutes a rough class of indirect intentional communication involving a complex interaction of language-specific and communication-general phenomena. Conversationalists use verbal irony in conjunction with paralinguistic signals such as speech prosody. Researchers examining acoustic features of speech communication usually focus on how prosodic information relates to the surface structure of utterances, and often ignore prosodic phenomena associated with implied meaning. In the case of verbal irony, there exists some debate concerning how these prosodic features manifest themselves in conversation. A (...) form-function approach can provide a valuable tool for understanding speakers' varied vocal strategies in this domain. Here I describe several ways conversationalists employ prosodic contrasts, laughter, and other speech characteristics in their attempts to communicate effectively and efficiently. The presented examples, culled from spontaneous conversation recordings, reveal just a small sample of the enormous variation in delivery styles speakers adopt when communicating with ironic language.

Time’s arrow is necessary for progress from a past that has already happened to a future that is only potential until creatively determined in the present. But time’s arrow is unnecessary in Einstein’s so-called block universe, so there is no creative unfolding in an actual present. How can there be an actual present when there is no universal moment of simultaneity? Events in various places will have different presents according to the position, velocity, and nature of the perceiver. Standing against (...) this view is traditional common sense since we normally experience time’s arrow as reality and the present as our place in the stream of consciousness, but we err to imagine we are living in the actual present. The present of our daily experience is actually a specious present, according to E. Robert Kelly (later popularized by William James), or duration, according to Henri Bergson, an habitus, as elucidated by Kerby (1991), or, simply, the psychological present (Adams, 2010) – all terms indicating that our experienced present so consists of the past overlapping into the future that any potential for acting from the creative moment is crowded out. Yet, for philosophers of process from Herakleitos onward, it is the philosophies of change or process that treat time’s arrow and the creative fire of the actual present as realities. In this essay, I examine the most well known but possibly least understood process cosmology of Alfred North Whitehead to seek out this elusive but actual present. In doing so, I will also ask if process philosophy is itself an example of the creative imagination and if this relates to doing science. I conclude Whitehead's process philosophy falls short of allowing for the actual creative spontaneity of a dynamic (eternal) present. (shrink)

Why is there a long-standing debate about paraphrase in poetry? Everyone agrees that paraphrase can be useful; everyone agrees that paraphrase is no substitute for the poem itself. What is there to disagree about? Perhaps this: whether paraphrase can specify everything that counts as a contribution to the meaning of a poem. There are, we say, two ways to take the question; on one way of taking it, the answer is that paraphrase cannot. Does this entail that there is meaning (...) mysteriously locked in a poem, meaning that cannot be represented in any way other than via the poem itself? If that were so it would have profound implications for poetry’s capacity to convey insight. We suggest reasons for thinking that the entailment does not hold. Throughout, we connect the traditional debate over paraphrase, which has largely been conducted within the fields of philosophy and literary theory, with recent empirically oriented thinking about the communicability of meaning, represented by work in pragmatics. We end with a suggestion about what is to count as belonging to meaning, and what as merely among the things that determine meaning. (shrink)

_Theurgy and the Soul_ is a study of Iamblichus of Syria, whose teachings set the final form of pagan spirituality prior to the Christianization of the Roman Empire. Gregory Shaw focuses on the theory and practice of theurgy, the most controversial and significant aspect of Iamblichus's Platonism. Theurgy literally means "divine action." Unlike previous Platonists who stressed the elevated status of the human soul, Iamblichus taught that the soul descended completely into the body and thereby required the performance of (...) theurgic rites—revealed by the gods—to unite the soul with the One. Iamblichus was once considered one of the great philosophers whose views on the soul and the importance of ritual profoundly influenced subsequent Platonists such as Proclus and Damascius. The Emperor Julian followed Iamblichus's teachings to guide the restoration of traditional pagan cults in his campaign against Christianity. Although Julian was unsuccessful, Iamblichus's ideas persisted well into the Middle Ages and beyond. His vision of a hierarchical cosmos united by divine ritual became the dominant world view for the entire medieval world and played an important role in the Renaissance Platonism of Marsilio Ficino. Even Ralph Waldo Emerson wrote that he expected a reading of Iamblichus to cause a "revival in the churches." But modern scholars have dismissed him, seeing theurgy as ritual magic or "manipulation of the gods." Shaw, however, shows that theurgy was a subtle and intellectually sophisticated attempt to apply Platonic and Pythagorean teachings to the full expression of human existence in the material world.

A number of recent historians claim to have defeated what they call the ‘conflict thesis’, the idea that there exists some inevitable conflict between Darwinism and Christianity. This is often thought to be part of a broader ‘warfare thesis’, which posits an inevitable conflict between science and religion. But, all they have defeated is one, relatively uninteresting form of this thesis. There remain other forms of the conflict theses that remain entirely plausible, even in light of the historical record.

This paper explores the existential motivation for the formation of extremist echo chambers through a phenomenological analysis. We advance two claims. Firstly, following Ortega y Gasset, that virtuality is a constant framework for experience. And secondly, following Merleau-Ponty, that there is persistent embodiment in online spaces. On this account virtuality is a permanent feature of embodiment, existing prior to technological intervention while at the same time being modifiable by technological artefacts. Understanding virtuality in this way allows us to analyse the (...) existential phenomenological characteristics of extremist echo chambers online. We argue that due to the persistence of embodiment throughout, and the restructuring of the virtual axes of experience, such online spaces can and do influence political praxis in offline spaces.

This paper argues that Oswald Spengler has an innovative philosophical position on the nature and interrelation of mathematics and science. It further argues that his position in many ways parallels that of Martin Heidegger. Both held that an appreciation of the mathematical nature of contemporary science was critical to a proper appreciation of science, technology and modernity. Both also held that the fundamental feature of modern science is its mathematical nature, and that the mathematical operates as a projection that establishes (...) in advance the manner in which an object will present itself. They also assert that modern science, mathematics and metaphysics all have their roots in the ‘mathematical’, whose essence is itself nothing numerical. (shrink)

Growing concern with the panpsychist's ostensive inability to solve the ‘combination problem’ has led some authors to adopt a view titled ‘Cosmopsychism’. This position turns panpsychism on its head: rather than many tiny atomic minds, there is instead one cosmos-sized mind. It is supposed that this view voids the combination problem, however I argue that it does not. I argue that there is a ‘de-combination problem’ facing the cosmopsychist, which is equivalent to the combination problem as they are both concerned (...) with subjects being proper parts of other subjects. I then propose two methods for both theorists to avoid the problem of subject-subject proper parthood relations: a distinction between absolute and relative phenomenal unity, and a modification of the essential nature of subjects. Of these two options, I find the latter option wanting and propose that the first should be adopted. (shrink)

Earl Conee and Richard Feldman have recently argued that the evidential support relation should be understood in terms of explanatory coherence: roughly, one's evidence supports a proposition if and only if that proposition is part of the best available explanation of the evidence. Their thesis has been criticized through alleged counterexamples, perhaps the most important of which are cases where a subject has a justified belief about the future. Kevin McCain has defended the thesis against Byerly's counterexample. I argue that (...) McCain's defense is inadequate before pointing toward a more promising solution for explanationism. The Byerly–McCain exchange is important because it casts light on the difficult issues of the standards for justification and the nature of epistemic support. Furthermore, McCain's defense of explanationism about epistemic support represents an important recent development of the burgeoning explanationist program in epistemology and philosophy of science.

In this paper I consider the prospects for a skeptical version of infallibilism. For the reasons given above, I think skeptical invariantism has a lot going for it. However, a satisfactory theory of knowledge must account for all of our desiderata, including that our ordinary knowledge attributions are appropriate. This last part will not be easy for the infallibilist invariantist. Indeed, I will argue that it is much more difficult than those sympathetic to skepticism have acknowledged, as there are serious (...) problems with regarding paradigmatic, typical knowledge attributions as loose talk, exaggerations, or otherwise practical uses of language. So, I do not think the pragmatic story that skeptical invariantism needs is one that works without a supplemental error theory of the sort left aside by purely pragmatic accounts of knowledge attributions. In its place, I will offer a compromise pragmatic and error view that I think delivers everything that skeptics can reasonably hope to get. (shrink)

The development of synthetic biology calls for accurate understanding of the critical functions that allow construction and operation of a living cell. Besides coding for ubiquitous structures, minimal genomes encode a wealth of functions that dissipate energy in an unanticipated way. Analysis of these functions shows that they are meant to manage information under conditions when discrimination of substrates in a noisy background is preferred over a simple recognition process. We show here that many of these functions, including transporters and (...) the ribosome construction machinery, behave as would behave a material implementation of the informationmanaging agent theorized by Maxwell almost 150 years ago and commonly known as Maxwell’s demon (MxD). A core gene set encoding these functions belongs to the minimal genome required to allow the construction of an autonomous cell. These MxDs allow the cell to perform computations in an energy-efficient way that is vastly better than our contemporary computers. (shrink)

History and the modern sciences are characterized by what is sometimes called a methodological naturalism that disregards talk of divine agency. Some religious thinkers argue that this reflects a dogmatic materialism: a non-negotiable and a priori commitment to a materialist metaphysics. In response to this charge, I make a sharp distinction between procedural requirements and metaphysical commitments. The procedural requirement of history and the sciences—that proposed explanations appeal to publicly-accessible bodies of evidence—is non-negotiable, but has no metaphysical implications. The metaphysical (...) commitment is naturalistic, but is both a posteriori and provisional, arising from the fact that for more than 400 years no proposed theistic explanation has been shown capable of meeting the procedural requirement. I argue that there is nothing to prevent religious thinkers from seeking to overturn this metaphysically naturalistic stance. But in order to do so they would need to show that their proposed theistic explanations are the best available explanations of a range of phenomena. Until this has been done, the metaphysical naturalism of history and the sciences remains defensible. (shrink)

Theistic evolutionists often suggest that one can reconcile evolutionary theory with biblical teaching. But in fact Christians have accepted Darwinian theory only after reinterpreting the opening chapters of Genesis. Is such a reinterpretation justified? Within Western Christian thought, there exists a hermeneutical tradition that dates back to St Augustine and which offers guidelines regarding apparent conflicts between biblical teaching and natural philosophy (or “science”). These state that the literal meaning of the text may be abandoned only if the natural-philosophical conclusions (...) are established beyond doubt. But no large-scale scientific theory, such as Darwin’s, can claim this degree of certainty. It follows that to justify their reinterpretation of Genesis 1–3, Christians must either argue that the literal sense of the biblical text can be maintained or accept that the Augustinian view of biblical authority is untenable. Three alternative views are discussed: a first that attempts to limit the scope of biblical authority, a second that distinguishes between the Bible and the Word of God, and a third that abandons the idea that religious faith offers certain knowledge. While the third view seems the most defensible, it comes at a cost: the recognition that, as John Locke put it, “reason must be our last judge and guide in everything.”. (shrink)
