Jacques Monod (1971) argued that certain molecular processes rely critically on the property of chemical arbitrariness, which he claimed allows those processes to “transcend the laws of chemistry”. It seems natural, as some philosophers have done, to interpret this in modal terms: a biological relationship is chemically arbitrary if it is possible, within the constraints of chemical “law”, for that relationship to have been otherwise than it is. But while modality is certainly important for understanding chemical arbitrariness, understanding its biological (...) role also requires an account of the concrete causal-functional features that distinguish arbitrary from non-arbitrary phenomena. In this paper I elaborate on this under-emphasised aspect by offering a general account of these features: arbitrary relations are instantiated by mechanisms that involve molecular adapters, which causally couple two properties or processes which would otherwise be uncorrelated. Additionally, adapters work by acting as intermediate rather than cooperating causes. (shrink)

Two extremely detailed accounts of temporal experience can be found in the work of C. D. Broad. These accounts have been subject to considerable criticism. I argue that, when we look more carefully at Broad’s work, we find that much of this criticism fails to find its target. I show that the objection that ultimately proves troubling for Broad stems from his commitment to two principles: i) the Thin-PSA, and ii) the ‘Overlap’ claim. I use this result to demonstrate that (...) we can learn two extremely important lessons from Broad’s work on temporal experience. -/- The first lesson is that there is a structural problem facing any account that commits to these two principles. This is significant given that a number of recent accounts of temporal experience are so committed. The second lesson is that the problem facing these accounts stems only from commitment to the Thin-PSA and ‘Overlap’, rather than to commitment to a particular conception of how experiences are to be individuated. This, I argue, gives us reason to reject Tye’s recent claim that the problems facing accounts of temporal experience can be dissolved simply by making stipulations about how experiences are to be individuated.

For the past thirty years, the late Tom Regan bucked the trend among secular animal rights philosophers and spoke patiently and persistently to the best angels of religious ethics in a stream of publications that enjoins religious scholars, clergy, and lay people alike to rediscover the resources within their traditions for articulating and living out an animal ethics that is more consistent with their professed values of love, mercy, and justice. My aim in this article is to showcase some of (...) the wealth of insight offered in this important but under-utilized archive of Regan’s work to those of us, religious or otherwise, who wish to challenge audiences of faith to think and do better by animals.

This study in moral, political, and legal philosophy contends that it is morally impermissible to circumcise male minors without a medical indication (nontherapeutic circumcision). Male minors have a moral anticipatory autonomy right-in-trust not to be circumcised. This right depends on norms of autonomy and bodily integrity. These norms generate three direct non-consequentialist arguments against nontherapeutic circumcision: (1) the loss of nonrenewable functional tissue, (2) genital salience, and (3) limits on a parental right to permanently modify their sons' bodies. An indirect (...) argument holds (4) that if it is morally impermissible to remove the female prepuce (clitoral hood), then it is also morally impermissible to remove the male prepuce (foreskin). Although there is debate across medical cultures, a reasonable understanding supports the claim that nontherapeutic circumcision causes some harms and imposes unwarranted risks on male minors. The overall moral case applies to secular circumcisions and, with some qualifications, to religious circumcisions in Judaism and Islam. Arguments of political philosophy that invoke the freedom of religion, toleration, multiculturalism, and social meaning qualify somewhat, but do not eliminate, the case against circumcising male minors without a medical indication. Nevertheless, the arguments deployed in this study do not warrant legal interference at this time with secular and religious practices of nontherapeutic circumcision. (shrink)

In this article I argue that the value of epistemic justification cannot be adequately explained as being instrumental to truth. I intend to show that false belief, which is no means to truth, can nevertheless still be of epistemic value. This in turn will make a good prima facie case that justification is valuable for its own sake. If this is right, we will have also found reason to think that truth value monism is false: assuming that true belief does (...) have value, there is more of final epistemic value than mere true belief.

The standard treatment of conditional probability leaves conditional probability undefined when the conditioning proposition has zero probability. Nonetheless, some find the option of extending the scope of conditional probability to include zero-probability conditions attractive or even compelling. This article reviews some of the pitfalls associated with this move, and concludes that, for the most part, probabilities conditional on zero-probability propositions are more trouble than they are worth.

Much of the intuitive appeal of evidentialism results from conflating two importantly different conceptions of evidence. This is most clear in the case of perceptual justification, where experience is able to provide evidence in one sense of the term, although not in the sense that the evidentialist requires. I argue this, in part, by relying on a reading of the Sellarsian dilemma that differs from the version standardly encountered in contemporary epistemology, one that is aimed initially at the epistemology of (...) introspection but which generalizes to theories of perceptual justification as well.

To what extent are cognitive capacities, especially perceptual capacities, informationally encapsulated and to what extent are they cognitively penetrable? And why does this matter? Two reasons we care about encapsulation/penetrability are: (a) encapsulation is sometimes held to be definitional of modularity, and (b) penetrability has epistemological implications independent of modularity. I argue that modularity does not require encapsulation; that modularity may have epistemological implications independently of encapsulation; and that the epistemological implications of the cognitive penetrability of perception are messier than (...) is sometimes thought.

Human cognitive acts are directed towards objects extended in space of a wide range of different types. What follows is a new proposal for bringing order into this typological clutter. The theory of spatially extended objects should make room not only for the objects of physics but also for objects at higher levels, including the objects of geography and of related disciplines. It should leave room for different types of boundaries, including both the bona fide boundaries which we find in (...) the physical world and the fiat (or human-demarcation-induced) boundaries with which much of geography has to deal. Two distinct axiomatic theories of boundaries are accordingly presented, and the need for both is examined in some detail. The resultant dual framework is shown to have application above all for our understanding of issues involving contact, division, and separation, issues which have posed serious difficulties for the ontological theories of boundaries that have been proposed hitherto.

There is, in some quarters, concern about high–level machine intelligence and superintelligent AI coming up in a few decades, bringing with it significant risks for humanity. In other quarters, these issues are ignored or considered science fiction. We wanted to clarify what the distribution of opinions actually is, what probability the best experts currently assign to high–level machine intelligence coming up within a particular time–frame, which risks they see with that development, and how fast they see these developing. We thus (...) designed a brief questionnaire and distributed it to four groups of experts in 2012/2013. The median estimate of respondents was for a one in two chance that high-level machine intelligence will be developed around 2040-2050, rising to a nine in ten chance by 2075. Experts expect that systems will move on to superintelligence in less than 30 years thereafter. They estimate the chance is about one in three that this development turns out to be ‘bad’ or ‘extremely bad’ for humanity. (shrink)

Maurice Merleau-Ponty is often interpreted as claiming that opportunities for action are directly present in perceptual experience. However, he does not provide much evidence for how or why this would occur, and one can doubt that this is an appropriate interpretation of his phenomenological descriptions. In particular, it could be argued the Merleau-Pontyian descriptions mistakenly attribute pre-perceptual or post-perceptual elements such as allocation of attention or judgment to the perceptual experience itself. This paper argues for the Merleau-Pontyian idea that opportunities (...) for action are present in perceptual experience. It further argues that the phenomenological descriptions can be supported and explained via reference to contemporary research on motor imagery. In particular, it will be argued that non-conscious, covert motor imagery is used to prepare for and regulate skilled actions, and that it is plausible that this imagery combines with perception (likely vision) to create a single experience of the environment as enabling action. The paper will also show that contemporary views on motor imagery are broadly compatible with Merleau-Ponty’s aims. (shrink)

Recent work by Peijnenburg, Atkinson, and Herzberg suggests that infinitists who accept a probabilistic construal of justification can overcome significant challenges to their position by attending to mathematical treatments of infinite probabilistic regresses. In this essay, it is argued that care must be taken when assessing the significance of these formal results. Though valuable lessons can be drawn from these mathematical exercises (many of which are not disputed here), the essay argues that it is entirely unclear that the form of (...) infinitism that results meets a basic requirement: namely, providing an account of infinite chains of propositions qua reasons made available to agents.

What sort of logic do we get if we adopt a supervaluational semantics for vagueness? As it turns out, the answer depends crucially on how the standard notion of validity as truth preservation is recasted. There are several ways of doing that within a supervaluational framework, the main alternative being between “global” construals (e.g., an argument is valid iff it preserves truth-under-all-precisifications) and “local” construals (an argument is valid iff, under all precisifications, it preserves truth). The former alternative is by (...) far more popular, but I argue in favor of the latter, for (i) it does not suffer from a number of serious objections, and (ii) it makes it possible to restore global validity as a defined notion.

Quine’s desert is generally contrasted with Meinong’s jungle, as a sober ontological alternative to the exuberant luxuriance that comes with the latter. Here I focus instead on the desert as a sober metaphysical alternative to the Aristotelian garden, with its tidily organized varieties of flora and fauna neatly governed by fundamental laws that reflect the essence of things and the way they can be, or the way they must be. In the desert there are no “natural joints”; all the boundaries (...) we find are lines we have drawn, artificial fencings that merely reflect of our own demarcations, our classifications, our desperate need to ward off the flux and meet an excusable but ungrounded demand for order and stability. The desert returns a picture of reality that is radically anti-realist. And yet the picture does not amount to a form of irrealism. The desert is out there and is what it is regardless of how we feel. And it is not completely structureless. It’s just that the structure it has is very thin and does not correspond to the sort of structure that so-called metaphysical realists—and scientific realists alike—tend to attribute to it. (shrink)

I focus on three mereological principles: the Extensionality of Parthood (EP), the Uniqueness of Composition (UC), and the Extensionality of Composition (EC). These principles are not equivalent. Nonetheless, they are closely related (and often equated) as they all reflect the basic nominalistic dictum, No difference without a difference maker. And each one of them—individually or collectively—has been challenged on philosophical grounds. In the first part I argue that such challenges do not quite threaten EP insofar as they are either self-defeating (...) or unsupported. In the second part I argue that they hardly undermine the tenability of EC and UC as well. (shrink)

Will future lethal autonomous weapon systems (LAWS), or ‘killer robots’, be a threat to humanity? The European Parliament has called for a moratorium or ban of LAWS; the ‘Contracting Parties to the Geneva Convention at the United Nations’ are presently discussing such a ban, which is supported by the great majority of writers and campaigners on the issue. However, the main arguments in favour of a ban are unsound. LAWS do not support extrajudicial killings, they do not take responsibility away (...) from humans; in fact they increase the abil-ity to hold humans accountable for war crimes. Using LAWS in war would probably reduce human suffering overall. Finally, the availability of LAWS would probably not increase the probability of war or other lethal conflict—especially as compared to extant remote-controlled weapons. The widespread fear of killer robots is unfounded: They are probably good news. (shrink)

In "Evil and the Justice of God", N.T. Wright presses the point that attempting to solve the philosophical problem of evil is an immature response to the existence of evil--a response that belittles the real problem of evil, which is just the fact that evil is bad and needs to be dealt with. As you might expect, I am not inclined to endorse this sort of sweeping indictment of the entire field of research on the philosophical problem of evil. (I (...) sort of doubt that Wright really meant to either.) But I do think that there is a kernel of truth in what I take to be Wright's fundamental objection to attempts to solve the philosophical problem of evil. In the first section of what follows, I will try briefly to explain why. I will then go on to argue that, despite this fact, certain efforts at solving the problem of evil avoid Wright's objection. Indeed, drawing on recent work by Elenore Stump, I will argue that one perfectly legitimate way to try to solve the philosophical problem of evil is to follow precisely what seems to be the main piece of advice in "Evil and the Justice of God": namely, to look more seriously than we have at the attitudes taken toward evil by human authors of and characters in the Bible, and to attend more carefully to what the Bible says about how God deals with evil.

This book aims to develop certain aspects of Gottlob Frege’s theory of meaning, especially those relevant to intensional logic. It offers a new interpretation of the nature of senses, and attempts to devise a logical calculus for the theory of sense and reference that captures as closely as possible the views of the historical Frege. (The approach is contrasted with the less historically-minded Logic of Sense and Denotation of Alonzo Church.) Comparisons of Frege’s theory with those of Russell and others (...) are given. It is in the end shown that developing Frege’s theory in these ways reveals serious problems hitherto largely unnoticed, including those possibly rendering a Fregean intensional logic inconsistent even if his naïve class theory is excluded.

This is a supplement to our book "Le tribolazioni del filosofare. Comedia metaphysica ne la quale si tratta de li errori & de le pene de l’Infero". It features an entirely new canto of the poem (originally thought to be lost) along with an extensive commentary. The canto covers the first ring of the circle of the Sullen, which hosts the Adverse to the Possible, and deals with several philosophical questions concerning the metaphysics of modality.

This paper defends a new argument for enabling citizen participation in government: individuals must have genuine opportunities to try to change the law in order to be able to satisfy duties of conscience. Without such opportunities, citizens who regard systems of related laws as partially unjust face a moral dilemma. If they comply with these laws willingly without also trying to change them, they commit a pro tanto wrong by willingly participating in injustice . If they disobey, or if they (...) obey only to avoid sanction, they respond inadequately to the morally important purposes that the laws advance despite their injustice. Government should help citizens avoid this dilemma. This argument bolsters the non-instrumentalist view that responsiveness in the political process is desirable even if it does not promote just legislative outcomes. It also helps to explain what governments owe to citizens with minority political views. (shrink)

In this essay, the tension that Benacerraf identifies for theories of mathematical truth is used as the vehicle for arguing against a particular desideratum for semantic theories. More specifically, I place in question the desideratum that a semantic theory, provided for some area of discourse, should run in parallel with the semantic theory holding for the rest of the language. The importance of this desideratum is also made clear by means of tracing out the subtle implications of its rejection.

This article aims to serve as an accessible introduction to the idea of "ontotheology" and to the so-called "ontotheological critique of Western metaphysics" for which the twentieth-century German philosopher Martin Heidegger is especially well known. I begin by distinguishing two uses of "ontotheology" employed respectively by Kant and Heidegger, and go on to develop the Heideggerian interpretation and critique of ontotheology under three main headings: The Onto-theo-logical Constitution of Western Metaphysics; Ontotheology's Problematic Legacy: Anxiety, Calculation, Oblivion; and Ontotheology and God. (...) The article concludes with an annotated bibliography of helpful resources for learning more about ontotheology, the critique of ontotheology, and directions the critique has taken after Heidegger.

I argue that Universalism (the thesis that mereological composition is unrestricted) entails Extensionalism (the thesis that sameness of composition is sufficient for identity) as long as the parthood relation is transitive and satisfies the Weak Supplementation principle (to the effect that whenever a thing has a proper part, it has another part disjoint from the first).

Though most children can easily answer the question, "Who's your daddy?", the concept of paternity is complex and multifaceted. Courts have stumbled in answering it. In order to ground paternal rights and obligations in a satisfactory way, we need to disaggregate the various elements of stereotypical paternity. It is not sufficient merely to separate social from biological paternity. The latter concept, itself, is complex. We need to separate the procreative element of paternity from the genetic relationship.

The philosophy of AI has seen some changes, in particular: 1) AI moves away from cognitive science, and 2) the long term risks of AI now appear to be a worthy concern. In this context, the classical central concerns – such as the relation of cognition and computation, embodiment, intelligence & rationality, and information – will regain urgency.

Leibniz said that the universe, if God-created, would exist at a unique, conjoint, physical maximum: Of all possible worlds, it would be richest in phenomena, but its richness would arise from the simplest physical laws and initial conditions. Using concepts of ‘‘variety’’ and algorithmic informational complexity, Leibniz’ claim can be reframed as a testable theory. This theory predicts that the laws and conditions of the actual universe should be simpler, and the universe richer in phenomena, than the presence of observers (...) would require. Tegmark has shown that inhabitants of an infinite multiverse would likely observe simple laws and conditions, but also phenomenal richness just great enough to explain their existence. Empirical observations fit the claim of divine choice better than the claim of an infinite multiverse. The future of the universe, including its future information-processing capacity, is predicted to be endless. -/- . (shrink)

I defend the thesis that psychological states can be literally ascribed only to living creatures and not to nonliving machines, such as sophisticated robots. Defenders of machine consciousness do not sufficiently appreciate the importance of the biological nature of a subject for the psychological significance of its behavior. Simulations of a computer-controlled, nonliving autonomous robot cannot carry the same psychological meaning as animate behavior. Being a living creature is an essential link between genuinely expressive behavior and justified psychological ascriptions.

One logic or many? I say—many. Or rather, I say there is one logic for each way of specifying the class of all possible circumstances, or models, i.e., all ways of interpreting a given language. But because there is no unique way of doing this, I say there is no unique logic except in a relative sense. Indeed, given any two competing logical theories T1 and T2 (in the same language) one could always consider their common core, T, and settle (...) on that theory. So, given any language L, one could settle on the minimal logic T0 corresponding to the common core shared by all competitors. That would be a way of resisting relativism, as long as one is willing to redraw the bounds of logic accordingly. However, such a minimal theory T0 may be empty if the syntax of L contains no special ingredients the interpretation of which is independent of the specification of the relevant L-models. And generally—I argue—this is indeed the case. (shrink)

Judith Butler’s influential work in feminist theory is significant for its insight that sexist discourse in popular culture affects the agency and consciousness of individuals, but offers an inadequate account of how such discourse might be said to touch, shape, or affect selves. Supplementing Butler’s account of signification with a Deweyan pragmatic account of meaning-making and selective emphasis enables a consistent account of the relationship between discourse and subjectivity with a robust conception of the bodily organism. An analysis of the (...) popular discourse surrounding Hillary Clinton in the 2008 Presidential campaign demonstrates why this hybrid pragmatic/poststructuralist account is necessary. (shrink)

One finds, in Maxwell's writings on thermodynamics and statistical physics, a conception of the nature of these subjects that differs in interesting ways from the way that they are usually conceived. In particular, though—in agreement with the currently accepted view—Maxwell maintains that the second law of thermodynamics, as originally conceived, cannot be strictly true, the replacement he proposes is different from the version accepted by most physicists today. The modification of the second law accepted by most physicists is a probabilistic (...) one: although statistical fluctuations will result in occasional spontaneous differences in temperature or pressure, there is no way to predictably and reliably harness these to produce large violations of the original version of the second law. Maxwell advocates a version of the second law that is strictly weaker; the validity of even this probabilistic version is of limited scope, limited to situations in which we are dealing with large numbers of molecules en masse and have no ability to manipulate individual molecules. Connected with this is his concept of the thermodynamic concepts of heat, work, and entropy; on the Maxwellian view, these are concepts that must be relativized to the means we have available for gathering information about and manipulating physical systems. The Maxwellian view is one that deserves serious consideration in discussions of the foundation of statistical mechanics. It has relevance for the project of recovering thermodynamics from statistical mechanics because, in such a project, it matters which version of the second law we are trying to recover. (shrink)

I articulate and the defend the following two claims: (i) it is a mistake to think that the structure of the world should mirror the structure of the theories by which we represent it, and through which we try to decipher it, simply because those theories appear to work; (ii) among the most deplorable consequences of this mistake is the widespread tendency to think that there must be a plurality of realities, or several different and irreducible levels of a stratified (...) reality, merely because our credo includes a plurality of theories each of which appears to be as important and trustworthy as it is irreducible to (if not overtly in conflict with) the others.

Neo-Humean instrumentalists hold that anagent's reasons for acting are grounded in theagent's desires. Numerous objections have beenleveled against this view, but the mostcompelling concerns the problem of ``aliendesires'' – desires with which the agent doesnot identify. The standard version ofneo-Humeanism holds that these desires, likeany others, generate reasons for acting. Avariant of neo-Humeanism that grounds anagent's reasons on her values, rather than allof her desires, avoids this implication, but atthe cost of denying that we have reasons to acton innocent whims. (...) A version of neo-Humeanismthat holds that an agent has reason to satisfyall of her desires that are not in conflictwith her values appears to allow us to grantthe reason-giving force of innocent whims whiledenying the reason-giving force of alien desires.

Certain consequentialists have responded to deontological worries regarding personal projects or options and agent-centered restrictions or constraints by pointing out that it is consistent with consequentialist principles that people develop within themselves, dispositions to act with such things in mind, even if doing so does not lead to the best consequences on every occasion. This paper argues that making this response requires shifting the focus of moral evaluation off of evaluation of individual actions and towards evaluation of whole character traits (...) and patterns of behavior. However, this weds consequentialism to a sort of psychological determinism, with which it is incompatible, because it makes any sort of assessment in terms of right or wrong incoherent. The paper concludes by sketching an ethical theory that abandons right and wrong as its organizing concepts, but nevertheless preserves much of the spirit of consequentialism. Relationships between whole patterns of behavior and the production of good and bad consequences can be studied and analyzed, and this information can be used to improve society and ourselves, without it being required that any individual persons acts or dispositions to behave be evaluated as right or wrong.

There is a natural philosophical impulse (and, correspondingly, a great deal of pressure) to always ask for explanations, for example, explanations of why we act as we do. Kevin Mulligan has gone a very long way in disentangling the many different because’s, and the many senses of ‘because’, that tend to clutter our efforts to manage that impulse. This short dialogue is meant as a humble tribute to his work in this area.

In the first section, I characterize skeptical theism more fully. This is necessary in order to address some important misconceptions and mischaracterizations that appear in the essays by Maitzen, Wilks, and O’Connor. In the second section, I describe the most important objections they raise and group them into four “families” so as to facilitate an orderly series of responses. In the four sections that follow, I respond to the objections.

In his latest book, Michael Devitt rejects Chomsky’s mentalist conception of linguistics. The case against Chomsky is based on two principal claims. First, that we can separate the study of linguistic competence from the study of its outputs: only the latter belongs to linguistic inquiry. Second, Chomsky’s account of a speaker’s competence as consisiting in the mental representation of rules of a grammar for his language is mistaken. I shall argue, first, that Devitt fails to make a case for separating (...) the study of outputs from the study of competence, and second, that Devitt mis-characterises Chomsky’s account of competence, and so his objections miss their target. Chomsky’s own views come close to a denial that speaker’s have knowledge of their language. But a satisfactory account of what speakers are able to do will need to ascribe them linguistic knowledge that they use to speak and understand. I shall explore a conception of speaker’s knowledge of language that confirrns Chomsky’s mentalist view of linguistics but which is immune to Devitt’s criticism. (shrink)

The theory that all processes in the universe are computational is attractive in its promise to provide an understandable theory of everything. I want to suggest here that this pancomputationalism is not sufficiently clear on which problem it is trying to solve, and how. I propose two interpretations of pancomputationalism as a theory: I) the world is a computer and II) the world can be described as a computer. The first implies a thesis of supervenience of the physical over computation (...) and is thus reduced ad absurdum. The second is underdetermined by the world, and thus equally unsuccessful as theory. Finally, I suggest that pancomputationalism as metaphor can be useful. – At the Paderborn workshop in 2008, this paper was presented as a commentary to the relevant paper by Gordana Dodig-Crnkovic " Info-Computationalism and Philosophical Aspects of Research in Information Sciences".

Cognition is commonly taken to be computational manipulation of representations. These representations are assumed to be digital, but it is not usually specified what that means and what relevance it has for the theory. I propose a specification for being a digital state in a digital system, especially a digital computational system. The specification shows that identification of digital states requires functional directedness, either for someone or for the system of which it is a part. In the case or digital (...) representations, to be a token of a representational type, where the function of the type is to represent.

On the face of it, Maurice Merleau-Ponty’s views bear a strong resemblance to contemporary disjunctivist theories of perception, especially John McDowell’s epistemological disjunctivism. Like McDowell (and other disjunctivists), Merleau-Ponty seems to be a direct realist about perception and holds that veridical and illusory perceptions are distinct. This paper furthers this comparison. Furthermore, it is argued that elements of Merleau-Ponty’s thought provide a stronger case for McDowell’s kind of epistemological view than McDowell himself provides. Merleau-Ponty’s early thought can be used to (...) develop a unique version of epistemological disjunctivism that is worth consideration alongside contemporary views on perceptual knowledge.

It is not a particularly hard thing to want or seek explanations. In fact, explanations seem to be a large and natural part of our cognitive lives. Children ask why and how questions very early in development and seem genuinely to want some sort of answer, despite our often being poorly equipped to provide them at the appropriate level of sophistication and detail. We seek and receive explanations in every sphere of our adult lives, whether it be to understand why (...) a friendship has foundered, why a car will not start, or why ice expands when it freezes. Moreover, correctly or incorrectly, most of the time we think we know when we have or have not received a good explanation. There is a sense both that a given, successful explanation satisfies a cognitive need, and that a questionable or dubious explanation does not. There are also compelling intuitions about what make good explanations in terms of their form, that is, a sense of when they are structured correctly. (shrink)

Empirical philosophers of science aim to base their philosophical theories on observations of scientific practice. But since there is far too much science to observe it all, how can we form and test hypotheses about science that are sufficiently rigorous and broad in scope, while avoiding the pitfalls of bias and subjectivity in our methods? Part of the answer, we claim, lies in the computational tools of the digital humanities, which allow us to analyze large volumes of scientific literature. Here (...) we advocate for the use of these methods by addressing a number of large-scale, justificatory concerns—specifically, about the epistemic value of journal articles as evidence for what happens elsewhere in science, and about the ability of DH tools to extract this evidence. Far from ignoring the gap between scientific literature and the rest of scientific practice, effective use of DH tools requires critical reflection about these relationships. (shrink)

The concern of deductive logic is generally viewed as the systematic recognition of logical principles, i.e., of logical truths. This paper presents and analyzes different instantiations of the three main interpretations of logical principles, viz. as ontological principles, as empirical hypotheses, and as true propositions in virtue of meanings. I argue in this paper that logical principles are true propositions in virtue of the meanings of the logical terms within a certain linguistic framework. Since these principles also regulate and control (...) the process of deduction in inquiry, i.e., they are prescriptive for the use of language and thought in inquiry, I argue that logic may, and should, be seen as an instrument or as a way of proceeding (modus procedendi) in inquiry.

We make some remarks on the mathematics and metaphysics of the hole argument, in response to a recent article in this journal by Weatherall ([2018]).

There is much discussion about whether the human mind is a computer, whether the human brain could be emulated on a computer, and whether at all physical entities are computers (pancomputationalism). These discussions, and others, require criteria for what is digital. I propose that a state is digital if and only if it is a token of a type that serves a particular function - typically a representational function for the system. This proposal is made on a syntactic level, assuming (...) three levels of description (physical, syntactic, semantic). It suggests that being digital is a matter of discovery or rather a matter of how we wish to describe the world, if a functional description can be assumed. Given the criterion provided and the necessary empirical research, we should be in a position to decide on a given system (e.g. the human brain) whether it is a digital system and can thus be reproduced in a different digital system (since digital systems allow multiple realization).
