Explication usually plays the role of the method of language revision. The paper sticks to the Carnapian project of explication and develops some of the formal requirements imposed on the explicatum. However, it departs from Carnap’s view when it comes to how to construe the simplicity condition. It is suggested that in some cases the simplicity condition, which in the Carnapian project plays the derived role with respect to the other three conditions—the similarity, exactness, and fruitfulness conditions—may be substantive for (...) the overall evaluation of explications. Based on a case study of three different explications of the H-D concept of confirmation :391–437, 1991; Erkenntnis 41:183–188, 1994; Gemes in Philos Sci 60:477–487, 1993; Erkenntnis 49:1–20, 1998; Sprenger in Philos Compass 6:497–508, 2011), we show that there are cases where competing explicata of a common explicandum satisfy the first three conditions equally well. In those cases, then, the simplicity condition is supposed to make the difference. However, instead of using Carnap’s construal of simplicity, we suggest a Principle of instrumental simplicity according to which, ceteris paribus, the simpler the explicatum is, the more likely is its ‘survival’ in competition with other explicata. Moreover, it is suggested that whereas the similarity, exactness and fruitfulness conditions are, in some sense, formal criteria, the simplicity condition is rather tested empirically. (shrink)

Proponents of the no-miracles argument contend that scientific realism is “the only philosophy that doesn’t make the success of science a miracle.” Bas van Fraassen argued, however, that the success of our best theories can be explained in Darwinian terms—by the fact they are survivors of a winnowing process in which unsuccessful theories are rejected. Critics of this selectionist explanation complain that while it may account for the fact we have chosen successful theories, it does not explain why any particular (...) one of those theories succeeds. Against this I defend the claim that if selectionists manage to account for the former, they have no burden to account for the latter; the success of any particular one of our best theories might as well be an extraordinary coincidence. I refer to this enhanced selectionist reply as “coincidentalism” and argue that it is a serious but underappreciated response to the no-miracles argument. More generally, I argue the considerations raised in favor of this response show that versions of the no-miracles argument focusing on the success of particular theories are misguided. (shrink)

A logical empiricist “baseline statement” can formalize some propositions established by a body of evidence or set of observations. However, it may not necessarily capture, of two propositions it entails, whether all the subsets of the evidence that establish one proposition also establish the other, vice versa, or neither. Yet, according to this paper, which obtains should sometimes matter for confirmation. It illustrates by showing how this “evidential dependence” can be used to address problems with generalizations of grue-like predicates, and (...) do so still within a very simple broadly Hempelian framework.

Recently it has been argued that certain neuropsychological findings on the decision-making, instrumental learning, and moral understanding in psychopathic offenders offer reasons to consider them not criminally responsible, due to certain epistemic and volitional impairments. We reply to this family of arguments, that collectively we call the irresponsibility of the psychopath argument. This type of argument has a premise that describes or prescribes the deficiencies that grant or should grant partial or complete criminal exculpation. The other premise contends that neuropsychological (...) evidence shows that psychopaths have incapacitates that are sufficient to ascribe complete or partially exculpatory deficiencies. The focus of our criticism is this latter premise. We argue that it requires that psychopathy should correlate significantly with certain rational incapacities that manifest across contexts. We show that the available neuropsychological data do not support the claim that psychopaths have such general exculpatory incapacities. (shrink)

It has long been known that the popular account of egocentric thoughts developed by David Lewis is in conflict with a natural account of communication, according to which successful communication requires the transmission of a thought content from speaker to hearer. In this paper, I discuss a number of proposed attempts to reconcile these two accounts of egocentric thought and communication. Each of them postulates two kinds of mental content, where one is egocentric, and the other is transmitted from speaker (...) to hearer in communication. I argue that Ninan’s account, which involves multi-centered contents, and Kölbel’s and Moss’s accounts, which postulate centered and uncentered proxy contents, respectively, are unsatisfactory. Therefore, I propose a two-dimensionalist account, according to which egocentric thoughts are represented by primary intensions, while the thoughts shared by speaker and hearer in cases of successful communication are represented by secondary intensions. Finally, I argue that aside from being able to reconcile Lewis’s account of egocentric thoughts with the natural account of communication, two-dimensionalism also provides the means for modeling agreement and disagreement.

In the introduction to his Realism, mathematics and modality, and in earlier papers included in that collection, Hartry Field offered an epistemological challenge to platonism in the philosophy of mathematics. Justin Clarke-Doane Truth, objects, infinity: New perspectives on the philosophy of Paul Benacerraf, 2016) argues that Field’s challenge is an illusion: it does not pose a genuine problem for platonism. My aim is to show that Clarke-Doane’s argument relies on a misunderstanding of Field’s challenge.

It's widely supposed that unification is an epistemic virtue: the degree to which a theory is unified contributes to its overall confirmation. However, this supposition has consequences which haven't been noted, and which undermine the leading accounts of unification. For, given Hempel's equivalence condition, any epistemic virtue must be such that logically equivalent theories must equally well unify any body of evidence, and logically equivalent bodies of evidence must be equally well unified by any theory. Yet the leading accounts of (...) unification in Bayesian terms, or those in terms of argument patterns, cannot satisfy these constraints conditions. The reason for this runs deep: these accounts of unification make unity depend on factors that vary between equivalent theories: the probabilistic relations of their components, or their relations to argument patterns. The solution is to abandon such accounts and instead adopt an account of unity based on worldly relations such as causation, rather than inferential relations. Such an account effortlessly satisfies the equivalence conditions, and so may describe the epistemic virtue of unity. (shrink)

One of the main logical functions of the truth predicate is to enable us to express so-called ‘infinite conjunctions’. Several authors claim that the truth predicate can serve this function only if it is fully disquotational, which leads to triviality in classical logic. As a consequence, many have concluded that classical logic should be rejected. The purpose of this paper is threefold. First, we consider two accounts available in the literature of what it means to express infinite conjunctions with a (...) truth predicate and argue that they fail to support the necessity of transparency for that purpose. Second, we show that, with the aid of some regimentation, many expressive functions of the truth predicate can actually be performed using truth principles that are consistent in classical logic. Finally, we suggest a reconceptualisation of deflationism, according to which the principles that govern the use of the truth predicate in natural language are largely irrelevant for the question of what formal theory of truth we should adopt. Many philosophers think that the paradoxes pose a special problem for deflationists; we will argue, on the contrary, that deflationists are in a much better position to deal with the paradoxes than their opponents.

Bird’s Essays in Collective Epistemology, Oxford University Press, Oxford, 2014) account of social knowledge denies that scientific social knowledge supervenes solely on the mental states of individuals. Lackey objects that SK cannot accommodate a knowledge-action principle and the role of group defeaters. I argue that Lackey’s knowledge-action principle is ambiguous. On one disambiguation, it is false; on the other, it is true but poses no threat to SK. Regarding group defeaters, I argue that there are at least two options available (...) to the defender of SK, both taken from literature on individual defeaters and applied to group defeaters. Finally, I argue that Lackey’s description of the case of Dr. N.—as a case in which the scientific community does not know but is merely in a position to know—is mistaken. It assumes that Dr. N.’s publication is not scientific knowledge. An analogy to the individual case shows that it is plausible that the scientific community is not merely in a position to know, although its members are. This leaves intact a conception of social knowledge on which it does not supervene on the mental states of individuals. (shrink)

It has recently been argued that indeterminacy and indeterminism make most ordinary counterfactuals false. I argue that a plausible way to avoid such counterfactual skepticism is to postulate the existence of primitive modal facts that serve as truth-makers for counterfactual claims. Moreover, I defend a new theory of ‘might’ counterfactuals, and develop assertability and knowledge criteria to suit such unobservable ‘counterfacts’.

As far as our experience goes, we live in a dynamic present. Those two phenomenal features of experience—presentness and dynamism—are obviously connected. However, how they are connected is not obvious at all. In this paper, I criticise the view according to which the former can explain the latter, which I call sophisticated representationalism. My criticism will be based on an ambiguity in the notion of tense found in the philosophical literature, that between the perspectival understanding and the dynamic understanding of (...) tenses. The distinction is not just of independent interest, but it has a role in providing indirect evidence for the claim that the feeling of passage of time should be understood in non-representationalist terms.

Indicative judgments pertain to what is true. Epistemic modal judgments pertain to what must or might be true relative to a body of information. A standard view is that epistemic modals implicitly quantify over alternative possibilities, or ways things could turn out. On this view, a proposition must be true just in case it is true in all the possibilities consistent with the available information, and a proposition might be true just in case it is true in at least one (...) possibility consistent with the available information. I report three experiments testing this view of epistemic modals. The results show that although modal judgments are sensitive to information about alternative possibilities, the standard quantification theory mischaracterizes the ordinary meaning of modals. I then report two more experiments testing the hypothesis that epistemic modals express willingness to attribute knowledge based on the available information. The results support this hypothesis. The results also show that the difference between “inside” and “outside” probabilistic information, familiar from the judgment and decision-making literature, affects epistemic modal judgments.

Mark Schroeder’s expressivist program has made substantial progress in providing a compositional semantics for normative terms. This paper argues that it risks achieving this semantic progress at the cost of abandoning a key theoretical motivation for embracing expressivism in the first place. The problem can be summarized as a dilemma. Either Schroeder must allow that there are cases in which agents are in disagreement with one another, or can make valid inferences, but that these disagreements or inferences are not expressible (...) in natural language; or his version of expressivism must abandon one of the key theoretical advantages expressivist theories seemed to possess over cognitivism, the ability to provide a very straightforward explanation of the action- and attitude-guiding role of normative judgments.

Sometimes it is epistemically beneficial to form a belief on authority. When you do, what happens to other reasons you have for that belief? Linda Zagzebski’s total-preemption view says that these reasons are “preempted”: you still have them, but you do not use them to support your belief. I argue that this situation is problematic, because having reasons for a belief while not using them forfeits you doxastic justification. I present an alternative account of belief on authority, the proper-basing view, (...) which enables the agent to base her belief on as many reasons as she has. A salient result is that the notion of a preemptive reason, useful though it may be in accounting for acting on authority, does not have any place in an account of believing on authority or in epistemology more generally.

This paper considers the prospects for a theory of intergenerational rights in light of certain ontologies of time. It is argued that the attempt to attribute rights to future persons or obligations to present persons towards future persons, faces serious difficulties if the existence of the future is denied. The difficulty of attributing rights to non-existent future persons is diagnosed as a particularly intractable version of the ‘problem of cross-temporal relations’ that plagues No-Futurist views like presentism. I develop a version (...) of the problem of cross-temporal relations regarding cross-temporal normative relations. I then consider and reject various solutions to the problem available to No-Futurists. The upshot of the discussion is that which ontology of time we choose sets constraints on the kinds of explanations we may offer for our future-directed obligations. (shrink)

objects are standardly taken to be causally inert, but this claim is rarely explicitly argued for. In the context of his platonism about musical works, in order for musical works to be audible, Julian Dodd argues that abstracta are causally efficacious in virtue of their concrete tokens participating in events. I attempt to provide a principled argument for the causal inertness of abstracta by first rejecting Dodd’s arguments from events, and then extending and generalizing the causal exclusion argument to the (...) abstract/concrete distinction. For reasons of parsimony, if concrete tokens or instantiations of abstract objects account for all causal work, then there is no reason to attribute causal efficacy to abstracta, and thus reason to maintain their causal inertness. I then consider how one of the main arguments against causal exclusion, namely Stephen Yablo’s notion of “proportionality”, could be modified to support the causal efficacy of abstracta. I argue that from a few simple premises Yablo’s account in fact supports their causal inertness. Having a principled reason for the causal inertness of abstracta appears to entail that the musical platonist must admit that we never literally hear the musical work, but only its performances. I sketch a solution to this problem available to Dodd, so that the musical platonist can maintain that musical works are abstract objects and are causally inert while retaining their audibility.

This paper defends the permissibility solution to the lottery paradox against an objection by Anna-Maria Asunta Eder. Eder argues that the permissibility solution should also be applicable to the preface paradox, but conflicts with a plausible principle about epistemic permissions when so applied. This paper replies by first criticizing Eder’s considerations in defense of her principle; in particular, it argues that the plausibility of her principle is to a large extent parasitic on the spurious plausibility of the principle of factual (...) detachment. The paper then presents a direct argument against Eder’s principle, which shows that her principle conflicts with a Pareto-style condition on permissible belief. (shrink)

According to one of the more popular endurantist packages on the market, a package I will call multilocational endurantism, enduring objects are exactly located at multiple instantaneous regions of spacetime. However, for all we know, the world might turn out to be spatiotemporally gunky and spatiotemporal gunk entails that this package is false. The goal of this paper is to sketch a view which retains the spirit of multilocational endurantism while also recognizing the possibility of certain types of objects which (...) endure through gunk.

My main aim is to argue that most conceptions of doxastic agency do not respond to the skeptic’s challenge. I begin by considering some reasons for thinking that we are not doxastic agents. I then turn to a discussion of those who try to make sense of doxastic agency by appeal to belief’s reasons-responsive nature. What they end up calling agency is not robust enough to satisfy the challenge posed by the skeptics. To satisfy the skeptic, one needs to make (...) sense of the possibility of believing for nonevidential reasons. While this has been seen as an untenable view for both skeptics and anti-skeptics, I conclude by suggesting it is a position that has been too hastily dismissed. (shrink)

Edouard Machery has argued that the notion of concept should be eliminated from scientific theorising about cognition on the grounds that what psychologists call concepts do not form a natural kind and that keeping this notion would encumber scientific progress. His view is that the class of concepts really divides into three distinct yet co-referential kinds of bodies of knowledge typically used in distinct cognitive processes. The main purpose of this paper is to challenge Machery’s eliminativist conclusion on the grounds (...) that his alternative to concepts fails to be combined with any prominent account of content determination. As a case of philosophical scrutiny of a psychological proposal, the paper also intends to show how philosophical and psychological interests in concepts can be brought together. (shrink)

Wright holds that the following two theses are jointly incoherent: Rules determine correct language use. These rules are discoverable via internal reflection on language use. I argue that incoherence is derivable from alone and examine two types of probabilistic accounts that model a modification of, one in terms of inexact knowledge, the other in terms of viewing semantic rules as reasons for linguistic actions. Both accommodate tolerance by breaking the link between justified assertion and truth, but incoherence threatens their conception (...) of justified assertion. I argue that the rules-as-reasons approach can relocate sharp boundaries to a place where they are not only more tolerable, but to be expected. (shrink)

I argue that information is a goal-relative concept for Bayesians. More precisely, I argue that how much information is provided by a piece of evidence depends on whether the goal is to learn the truth or to rank actions by their expected utility, and that different confirmation measures should therefore be used in different contexts. I then show how information measures may reasonably be derived from confirmation measures, and I show how to derive goal-relative non-informative and informative priors given background (...) information. Finally, I argue that my arguments have important implications for both objective and subjective Bayesianism. In particular, the Uniqueness Thesis is either false or must be modified. Moreover, objective Bayesians must concede that pragmatic factors systematically influence which priors are rational, and subjective Bayesians must concede that pragmatic factors sometimes partly determine which prior distribution most accurately represents an agent’s epistemic state.

Are there different sizes of infinity? That is, are there infinite sets of different sizes? This is one of the most natural questions that one can ask about the infinite. But it is of course generally taken to be settled by mathematical results, such as Cantor’s theorem, to the effect that there are infinite sets without bijections between them. These results settle the question, given an almost universally accepted principle relating size to the existence of functions. The principle is: for (...) any sets A and B, if A is the same size as B, then there is a bijection from A to B. The aim of the paper, however, is to argue that this question is in fact wide open: to argue that we are not in a position to know the answer, because we are not in one to know the principle. The aim, that is, is to argue that for all we know there is only one size of infinity. (shrink)

Nominalism about attributes has serious difficulties in accounting for truths involving abstract nouns. Prominent among such truths are statements of comparative similarity among attributes. This paper argues that one cannot account for the truth of such statements without invoking attributes.

The “received wisdom” in contemporary analytic philosophy is that intuition talk is a fairly recent phenomenon, dating back to the 1960s. In this paper, we set out to test two interpretations of this “received wisdom.” The first is that intuition talk is just talk, without any methodological significance. The second is that intuition talk is methodologically significant; it shows that analytic philosophers appeal to intuition. We present empirical and contextual evidence, systematically mined from the JSTOR corpus and HathiTrust’s Digital Library, (...) which provide some empirical support for the second rather than the first hypothesis. Our data also suggest that appealing to intuition is a much older philosophical methodology than the “received wisdom” alleges. We then discuss the implications of our findings for the contemporary debate over philosophical methodology. (shrink)

In this paper we present tableau methods for two-dimensional modal logics. Although models for such logics are well known, proof systems remain rather unexplored as most of their developments have been purely axiomatic. The logics herein considered contain first-order quantifiers with identity, and all the formulas in the language are doubly-indexed in the proof systems, with the upper indices intuitively representing the actual or reference worlds, and the lower indices representing worlds of evaluation—first and second dimensions, respectively. The tableaux modulate (...) over different notions of validity such as local, general, and diagonal, besides being general enough for several two-dimensional logics proposed in the literature. We also motivate the introduction of a new operator into two-dimensional languages and explore some of the philosophical questions raised by it concerning the relations there are between actuality, necessity, and the a priori, that seem to undermine traditional intuitive interpretations of two-dimensional operators.

The focus of this paper will be on singular thoughts. In the first section I will present Jeshion’s cognitivism; a view that holds that one should characterize singular thoughts by their cognitive roles. In the second section I will argue that, contrary to Jeshion’s claims, results from studies of object tracking in cognitive psychology do not support cognitivism. In the third section I will discuss Jeshion’s easy transmission of singular thought and argue that it ignores a relevant distinction between general (...) and specific understanding of names. Finally, the last section will argue that conscious attention should replace Jeshion’s significance condition as a necessary condition for one to have a singular thought. The paper will show that we need to take seriously the acquaintance requirement for singular thoughts, as even the easy transmission of singular thoughts with the use of names will be called into question.

Derivational robustness may increase the degree to which various pieces of evidence indirectly confirm a robust result. There are two ways in which this increase may come about. First, if one can show that a result is robust, and that the various individual models used to derive it also have other confirmed results, these other results may indirectly confirm the robust result. Confirmation derives from the fact that data not known to bear on a result are shown to be relevant (...) when it is shown to be robust. Second, robustness may increase the degree to which the robust result is indirectly confirmed if it increases the weight with which existing evidence indirectly confirms it. This may happen when it strengthens the connection between the core and the robust result by showing that auxiliaries are not responsible for the result. (shrink)

The problem of error is an old argument for atheism that can be found in Medieval and Early Modern Philosophy. Although it is not widely discussed in the contemporary literature in the Philosophy of Religion, I resurrect it and give it a modern spin. By relying on empirical studies in moral psychology that demonstrate that moral judgments from human beings are generally susceptible to certain psychological biases, such as framing and order effects, I claim that if God is responsible for (...) making human beings such that we have these biases, this means that God is not a perfect being. The findings in empirical moral psychology create a problem for the existence of God, traditionally conceived. (shrink)

In a recent paper Barnes proposes to characterize ontological emergence by identifying the emergent entities with those entities which are both fundamental and dependent. Barnes offers characterizations of the notions of fundamentality and dependence, but is cautious about committing to the specifics of these notions. This paper argues that Barnes’s characterization of emergence is problematic in several ways. Firstly, emergence is a relation, and merely delimiting relata of this relation tells us little about it. Secondly, the group of entities delimited (...) as dependent and fundamental do not appear to be the group of emergent entities. Rather, some entities appear to be dependent and fundamental and not emergent, whilst other entities appear to be emergent and not dependent and fundamental. The moral drawn is that in order to provide a characterization of emergence one must go beyond what Barnes says explicitly. It is also shown that a potentially fruitful way of doing this would be to further specify the notion of dependence at issue revealing it to be asymmetric and perhaps merely nomological. (shrink)

Perdurantists hold that we persons—just like other ordinary objects—persist by perduring, by having temporal parts, or stages, located over time. Perdurantists also standardly endorse the B-theory of time. And, in light of this endorsement, they typically characterize our tensed beliefs as self-ascriptions of properties, made not by us but by our stages. For instance, for me to believe that Angela Merkel is currently the chancellor of Germany is for my now-located stage to self-ascribe the property of being simultaneous with Merkel’s (...) chancellorship. The problem with this way of understanding tensed belief is that it undermines—if not outright contradicts—the perdurantist’s best options for resisting the Too Many Thinkers objection. In what follows, I show why this is. I then consider what I take to be the perdurantist’s most promising alternative account of tensed belief. I argue that this alternative either leaves perdurantists no better off with respect to the Too Many Thinkers objection or, instead, leaves them vulnerable to another objection, one that they would otherwise have no problem resisting.

Can scientific evidence prompt us to revise philosophical theories or folk theoretical accounts of phenomena of the mind? We will argue that it can—but only under the condition that they make a so-called ‘ontological commitment’ to something that is actually subject to empirical inquiry. In other words, scientific evidence pertaining to neuroanatomical structure or causal processes only has a refuting effect if philosophical theories and folk notions subscribe to either account. We will illustrate the importance of ‘ontological commitment’ with the (...) ‘neuroanatomical approach’ to amusement as proposed in a recent paper by Palencik :419–434, 2007). We will show that the scientific evidence presented in said neuroanatomical approach has no bearing on the conceptual issues, in that the philosophical theories and folk distinction that are criticized do not subscribe to any account of the underlying neuroanatomical structure or causal processes. Our suggestions in this paper are not limited to philosophical accounts of humor but apply to the relationship of philosophy, common sense and science in general. (shrink)

We explore which types of probabilistic updating commute with convex IP pooling. Positive results are stated for Bayesian conditionalization, imaging, and a certain parameterization of Jeffrey conditioning. This last observation is obtained with the help of a slight generalization of a characterization of externally Bayesian pooling operators due to Wagner :336–345, 2009). These results strengthen the case that pooling should go by imprecise probabilities since no precise pooling method is as versatile.

Christian List and Philip Pettit have recently developed a model of group agency on which an autonomous group agent can be formed, by deductive inference, from the beliefs and preferences of the individual group members. In this paper I raise doubts as to whether this type of group agent is a moral agent. The sentimentalist approach to moral responsibility sees a constitutive role for moral emotions, such as blame, guilt, and indignation, in our practices of attributing moral responsibility. These moral (...) emotions are important for the alignment of moral understandings, and for valuing other members of the moral community. I argue that while the intentional objects of beliefs and preferences are propositions, the intentional objects of moral emotions are other agents. Because agents are not subject to rules of inference, we cannot generate group agent emotions—such as guilt—in the same way as we can generate group agent beliefs and preferences. And because the group agents lack moral emotions, we have reason to resist treating them as moral agents. (shrink)

The Platonic account of modality says, roughly, that truths about alien possibilities are grounded in uninstantiated universals. Recently, Ingram has raised a problem for this kind of view, which is that it apparently requires negative facts to play a truthmaking role. Ingram offers an alternative Platonic account which makes use of modal instantiation relations. In this paper, I highlight some of the costs of Ingram’s new account and argue that a more appealing version of Platonism—and modal theory in general—is one (...) that is supplemented with an ontology of totality facts.

In Objectivity, Daston and Galison argue that scientific objectivity has a history. Objectivity emerged as a distinct nineteenth-century “epistemic virtue,” flanked in time by other epistemic virtues. The authors trace the origins of scientific objectivity by identifying changes in images from scientific atlases from different periods, but they emphasize that the same history could be narrated using different sorts of scientific objects. One could, for example, focus on the changing uses of “type specimens” in biological taxonomy. Daston :153–182, 2004) indeed (...) provides a detailed account of the history of the type specimen which purports to show this. I argue that this attempt hinges on a conceptual confusion and therefore fails. I show that the actual history of the type specimen does not reinforce the account of epistemic virtues from Objectivity, but rather threatens to subvert it. (shrink)

The paper discusses Bayesian convergence when the truth is excluded from the analysis by means of a simple coin-tossing example. In the fair-balance paradox a fair coin is tossed repeatedly. A Bayesian agent, however, holds the a priori view that the coin is either biased towards heads or towards tails. As a result the truth is ignored by the agent. In this scenario the Bayesian approach tends to confirm a false model as the data size goes to infinity. I argue (...) that the fair-balance paradox reveals an unattractive feature of the Bayesian approach to scientific inference and explore a modification of the paradox. (shrink)

This paper addresses the problem of judgment aggregation in science. How should scientists decide which propositions to assert in a collaborative document? We distinguish the question of what to write in a collaborative document from the question of collective belief. We argue that recent objections to the application of the formal literature on judgment aggregation to the problem of judgment aggregation in science apply to the latter, not the former question. The formal literature has introduced various desiderata for an aggregation (...) procedure. Proposition-wise majority voting emerges as a procedure that satisfies all desiderata which represent norms of science. An interesting consequence is that not all collaborating scientists need to endorse every proposition asserted in a collaborative document. (shrink)

It is an ongoing controversy whether natural selection is a cause of population change, or a mere statistical description of how individual births and deaths accumulate. In this paper I restate the problem in terms of the reference class problem, and propose how the structure of stable equilibrium can provide a solution in continuity with biological practice. Insofar natural selection can be understood as a tendency towards equilibrium, key statisticalist criticisms are avoided. Further, in a modification of the Newtonian-force analogy, (...) it can be suggested that a better metaphor for natural selection is that of an emergent force, similar in nature to entropic forces: with magnitude and direction, but lacking a spatiotemporal origin or point of application.

Many philosophical disputes, most prominently disputes in ontology, have been suspected of being merely verbal and hence pointless. My goal in this paper is to offer an account of merely verbal disputes and to address the question of what is problematic with such disputes. I begin by arguing that extant accounts that focus on the semantics of the disputed statement S do not capture the full range of cases as they might arise in philosophy. Moreover, these accounts bring in heavy (...) theoretical machinery. I attempt to show that we can capture the full range of cases with an approach that is theoretically lightweight. This approach explains verbal disputes as a pragmatic phenomenon where parties use the same utterance type S with different speaker’s meaning. Moreover, it provides an answer to the crucial question Jackson’s pragmatic account leaves, at best, highly implicit. Based on my account, we can distinguish between different ways in which disputes can be verbal and different extents to which they are defective. Distinguishing between these varieties of verbalness furthermore allows us to specify what kind of substantive issues remain to be discussed once the linguistic confusion is resolved. (shrink)

Though there is a wide and varied literature on ethical supererogation, there has been almost nothing written about its epistemic counterpart, despite an intuitive analogy between the two fields. This paper seeks to change this state of affairs. I will begin by showing that there are examples which intuitively feature epistemically supererogatory doxastic states. Next, I will present a positive theory of epistemic supererogation that can vindicate our intuitions in these examples, in an explanation that parallels a popular theory of (...) ethical supererogation. Roughly, I will argue that a specific type of epistemic virtue—the ability to creatively think up plausible hypotheses given a body of evidence—is not required of epistemic agents. Thus, certain exercises of this virtue can result in supererogatory doxastic states. In presenting this theory, I will also show how thinking about epistemic supererogation can provide us a new way forward in the debate about the uniqueness thesis for epistemic rationality. (shrink)

According to the Psychological Account of personal identity, personal identity across time is maintained by some form of psychological overlap or continuance. I show that the Psychological Account has trouble accommodating cases of transient retrograde amnesia. In such cases, the transitivity of psychological continuity may break down. I consider various means of responding to this problem, arguing that the best available response will undercut our ability to rely on intuitions about brain transplantation to support the Psychological Account. When the Psychological (...) Account is re-interpreted in such a way as to overcome the problems posed by cases of transient retrograde amnesia, it turns out that standard brain transplantation cases involve details which are strictly irrelevant according to the theory. On the other hand, these features seem to drive our intuitions about survival in these cases. In this way, my argument undermines one of the key motivations for adopting the Psychological Account.

Kantian philosophy of space, time and gravity is significantly affected in three ways by particle physics. First, particle physics deflects Schlick’s General Relativity-based critique of synthetic a priori knowledge. Schlick argued that since geometry was not synthetic a priori, nothing was—a key step toward logical empiricism. Particle physics suggests a Kant-friendlier theory of space-time and gravity presumably approximating General Relativity arbitrarily well, massive spin-2 gravity, while retaining a flat space-time geometry that is indirectly observable at large distances. The theory’s roots (...) include Seeliger and Neumann in the 1890s and Einstein in 1917 as well as 1920s–1930s physics. Such theories have seen renewed scientific attention since 2000 and especially since 2010 due to breakthroughs addressing early 1970s technical difficulties. Second, particle physics casts additional doubt on Friedman’s constitutive a priori role for the principle of equivalence. Massive spin-2 gravity presumably should have nearly the same empirical content as General Relativity while differing radically on foundational issues. Empirical content even in General Relativity resides in partial differential equations, not in an additional principle identifying gravity and inertia. Third, Kant’s apparent claim that Newton’s results could be known a priori is undermined by an alternate gravitational equation. The modified theory has a smaller symmetry group than does Newton’s. What Kant wanted from Newton’s gravity is impossible due its large symmetry group, but is closer to achievable given the alternative theory. (shrink)

The psychology and phenomenology of our knowledge of other minds is not well captured either by describing it simply as perception, nor by describing it simply as inference. A better description, I argue, is that our knowledge of other minds involves both through ‘perceptual co-presentation’, in which we experience objects as having aspects that are not revealed. This allows us to say that we perceive other minds, but perceive them as private, i.e. imperceptible, just as we routinely perceive aspects of (...) physical objects as unperceived. I discuss existing versions of this idea, particularly Joel Smith’s, on which it is taken to imply that our knowledge of other minds is, in these cases, perceptual and not inferential. Against this, I argue that perceptual co-presentation in general, and mind-perception in particular, yields knowledge that is simultaneously both perceptual and inferential. (shrink)

I suggest a way in which metaphysics might cure us of our desire for immortality. Supposing that time is composed of instants, or even that time could be composed of instants, leads to the conclusion that there is nothing good that immortality offers, nothing we might reasonably want, that is in principle unavailable to a mere mortal. My argument proceeds in three stages. First, I suggest a necessary condition for a feature to ground the desirability of a life or a (...) portion thereof. Second, after distinguishing between three different features that could plausibly be meant by ’immortality’, I argue that if time could be composed of instants, only one of those features satisfies the necessary condition, and it evidently fails to ground the desirability of a life. Third, I argue that no feature that entails any of the three features grounds the desirability of a life either. I conclude with reflections on what this means for our longing for immortality.

Philosophers have shown that the Aristotelian conception of mind and body is capable of resolving the problems confronting dualism. In this paper the resolution of the mind–body problem is extended with a scientific solution by integrating the Aristotelian framework with evolutionary theory. It is discussed how the theories of Fisher and Hamilton enable us to construct and solve hypotheses about how the mind evolved out of matter. These hypotheses are illustrated by two examples: the evolutionary transition from cells to multicellular (...) organisms, and the evolutionary transition from babbling to doing things with words and later reasoning and giving reasons. The first transitions resulted in the sensitive psyche of the other animals, the second in the rational psyche of humans. It is discussed how exploratory behaviour of lower-level entities facilitated these evolutionary transitions. (shrink)

Within the causal modeling literature, debates about the Causal Faithfulness Condition have concerned whether it is probable that the parameters in causal models will have values such that distinct causal paths will cancel. As the parameters in a model are fixed by the probability distribution over its variables, it is initially puzzling what it means to assign probabilities to these parameters. I propose that to assign a probability to a parameter in a model is to treat that parameter as a (...) function of a variable in an augmented model. By combining this proposal with widely adopted principles regarding which variables must be included in a model, I argue that the various proposed counterexamples to CFC involving coordinated parameters are not genuine counterexamples. I then consider the cases in which CFC fails due not to coordination, but by coincidence, and propose explanatory and predictive bases for ruling out such coincidences without presuming that they are improbable. The aim of the proposed defenses is not to show that CFC never fails, but rather to argue that its use in a particular context may be defended using general modeling assumptions rather than by relying on claims about how often it fails.

Some have argued that our intuitive reactions to a number of cases of moral responsibility can only be preserved at the expense of a unified account of moral responsibility for acts and omissions. I argue against this conclusion, proposing that a plausible condition on responsibility, the Causal Condition can, when properly elaborated, justify the relevant intuitive data.

Wolfgang Spohn’s Frege prize lecture, like the work on which it is based, is a tour de force of rich, elegant, coherent argument about how the projected world that we experience is constructed. But we do not live in this projected world nor reason about it. The things Spohn constructs are there from the start—or so my Stanford School pragmatism teaches. This paper explores a deep difference in philosophical approaches—Spohn’s elegant proofs versus the stocky, tangled arguments I advocate—and illustrates how (...) these play out in far more detailed disputes about the nature of causality and causal inference.

In this paper, I provide the framework for an account of group assertion. On my view, there are two kinds of group assertion, coordinated and authority-based, with authority-based group assertion being the core notion. I argue against a deflationary view, according to which a group’s asserting is understood in terms of individual assertions, by showing that a group can assert a proposition even when no individual does. Instead, I argue on behalf of an inflationary view, according to which it is (...) the group itself that asserts, a conclusion supported by the fact that paradigmatic features of assertion apply only at the level of the group. A central virtue of my account is that it appreciates the important relationship that exists between most groups and their spokespersons, as well as the consequences that follow from this relationship. My view, thus, provides the framework for distinguishing when responsibility for an assertion lies at the collective level, and when it should be shouldered by an individual simply speaking for herself.

This paper defends a deontological egalitarianism in the ethics of future generations. Concerns about the non-identity problem have been taken as a reason to develop sufficientarian approaches to intergenerational justice. This paper argues for a solution to the non-identity problem that refers to the claims of future persons. In principle, the content of these claims could be spelled out with a sufficientarian and an egalitarian approach. What speaks against sufficientarianism, however, is that the sufficiency threshold, unless it is set very (...) low, would have to be set arbitrarily. The hidden justification behind a higher threshold would be egalitarian. It draws its plausibility from the justified belief that future persons have a claim on us that we leave equally valuable shares of natural resources to them. (shrink)

Free action and microphysical determination are incompatible but this is so only in virtue of a genuine conflict between microphysical determination with any active behavior. I introduce active behavior as the veridicality condition of agentive experiences and of perceptual experiences and argue that these veridicality conditions are fulfilled in many everyday cases of human and non-human behavior and that they imply the incompatibility of active behavior with microphysical determination. The main purpose of the paper is to show that the view (...) proposed about active behavior leads to a natural compromise between libertarianism and compatibilism, which avoids the flaws of both positions while preserving their central insights.

The modalities come into the world by being projections or objectivizations of our epistemic constitution. Thus this paper is a statement of Humean projectivism. In fact, it goes beyond Simon Blackburn’s version. It is also designed as a comprehensive counter-program to David Lewis’ program of Humean supervenience. In detail, the paper explains: Already the basic fact that the world is a world of states of affairs is due to the nature of our epistemic states. Objects, which figure in states of (...) affairs and which embody metaphysical modality, are constitutable by their essential properties and in fact constituted by us according to our ontological policies. What the facts are, to which the correspondence notion of truth refers, is determined by applying an epistemic or pragmatic notion of truth to the world. Causation is a specific objectivization of our conditional beliefs. Nomicity is a ‘habit of belief’, a specific way of generalizing epistemic attitudes. This covers the basic metaphysical and natural modalities. The paper attempts to convey that talking of projection or objectivization is not just imagery, but a constructively realizable program.

It is sometimes claimed that the Bayesian framework automatically implements Ockham's razor---that conditionalizing on data consistent with both a simple theory and a complex theory more or less inevitably favours the simpler theory. It is shown here that the automatic razor doesn't in fact cut it for certain mundane curve-fitting problems.

I present a possible worlds semantics for a hyperintensional belief revision operator, which reduces the logical idealization of cognitive agents affecting similar operators in doxastic and epistemic logics, as well as in standard AGM belief revision theory. belief states are not closed under classical logical consequence; revising by inconsistent information does not perforce lead to trivialization; and revision can be subject to ‘framing effects’: logically or necessarily equivalent contents can lead to different revisions. Such results are obtained without resorting to (...) non-classical logics, or to non-normal or impossible worlds semantics. The framework combines, instead, a standard semantics for propositional S5 with a simple mereology of contents. (shrink)

In the history of external information systems, the World Wide Web presents a significant change in terms of the accessibility and amount of available information. Constant access to various kinds of online information has consequences for the way we think, act and remember. Philosophers and cognitive scientists have recently started to examine the interactions between the human mind and the Web, mainly focussing on the way online information influences our biological memory systems. In this article, we use concepts from the (...) extended cognition and distributed cognition frameworks and from transactive memory theory to analyse the cognitive relations between humans and the Web. We first argue that while neither of these approaches neatly capture the nature of human-Web interactions, both offer useful concepts to describe aspects of such interactions. We then conceptualize relations between the Web and its users in terms of cognitive integration, arguing that most current Web applications are not deeply integrated and are better seen as a scaffold for memory and cognition. Some highly personalised applications accessed on wearable computing devices, however, may already have the capacity for deep integration. Finally, we draw out some of the epistemic implications of our cognitive analysis. (shrink)

The Integrated Information Theory (IIT) is a leading scientific theory of consciousness, which implies a kind of panpsychism. In this paper, I consider whether IIT is compatible with a particular kind of panpsychism known as Russellian panpsychism, which purports to avoid the main problems of both physicalism and dualism. I will first show that if IIT were compatible with Russellian panpsychism, it would contribute to solving Russellian panpsychism’s combination problem, which threatens to show that the view does not avoid the (...) main problems of physicalism and dualism after all. I then show that IIT and Russellian panpsychism are not compatible as they currently stand, because of a problem which I will call the coarse-graining problem. After I explain the coarse-graining problem, I offer two possible solutions, each involving a small modification of IIT. Given either of these modifications, IIT and Russellian panpsychism may be fully compatible after all and jointly enable significant progress on the mind-body problem. (shrink)

It is fairly widely accepted that Saul Kripke, Keith Donnellan, and others showed in the 1960s-1980s that proper names, in particular uses by speakers, can refer to things free of anything like the epistemic requirements posited by Gottlob Frege and Bertrand Russell. This paper separates two aspects of the Frege-Russell view of name reference: (i) the metaphysical thesis that names in particular uses refer to things in virtue of speakers thinking of those things and (ii) the epistemic thesis that thinking (...) of things requires a means of determining (in the sense of figuring out or identifying) which thing one is thinking of. My question is whether the Kripke-Donnellan challenge should lead us to reject (i), (ii), or both. Contrary to a popular line of thinking that sees practices or conventions, rather than singular thinking, as determinative of linguistic reference, my answer is that we should reject only the epistemic thesis, not the metaphysical one.

The present paper unravels ontological and normative conditions of personhood for the purpose of critiquing ‘Cognitivist Views’. Such views have attracted much attention and affirmation by presenting the ontology of personhood in terms of higher-order cognition on the basis of which normative practices are explained and justified. However, these normative conditions are invoked to establish the alleged ontology in the first place. When we want to know what kind of entity has full moral status, it is tempting to establish an (...) ontology that fits our moral intuitions about who should qualify for such unique normative standing. But this approach conflates personhood’s ontology and normativity insofar as it stresses the primacy of the former while implicitly presupposing the latter; it thereby suffers from a ‘Normative Fallacy’ by inferring from ‘ought’ to ‘is’. Following my critique of Cognitivism, I sketch an alternative conception, contending that, whereas the Cognitivist ontology of personhood presupposes the normative, a social ontology is constituted by it. In due consideration of evidence from developmental psychology, the social embeddedness of persons—manifested in the ability of taking a ‘second-person stance’—is identified as a key feature of personhood that precedes higher-order cognition, and is directly linked to basic normative concerns.

While ideal interventions are acknowledged by many as valuable tools for the analysis of causation, recent discussions have shown that, since there are no ideal interventions on upper-level phenomena that non-reductively supervene on their underlying mechanisms, interventions cannot—contrary to a popular opinion—ground an informative analysis of constitution. This has led some to abandon the project of analyzing constitution in interventionist terms. By contrast, this paper defines the notion of a horizontally surgical intervention, and argues that, when combined with some innocuous (...) metaphysical principles about the relation between upper and lower levels of mechanisms, that notion delivers a sufficient condition for constitution. This, in turn, strengthens the case for an interventionist analysis of constitution. (shrink)

This paper investigates the representation of authors with different linguistic backgrounds in academic publishing. We first review some common rebuttals of concerns about linguistic injustice. We then analyze 1039 authors of philosophy journals, primarily selected from the 2015 Leiter Report. While our data show that Anglophones dominate the output of philosophy papers, this unequal distribution cannot be solely attributed to language capacities. We also discover that ethics journals have more Anglophone authors than logic journals and that most authors are affiliated (...) with English-speaking universities, suggesting other factors may also play significant roles. Moreover, some interesting results are revealed when we combine the factor of sex with place of affiliation and linguistic background. It indicates that while certain linguistic injustice is inevitable in academic publishing, it may be more complex than thought. We next introduce Broadbent’s :457–476, 2012, Philosophy of epidemiology, Palgrave Macmillan, New York, 2013, Stud Hist Philos Biol Biomed Sci 48:250–257, 2014) contrastive account of causation to give a causal explanation of our findings. Broadbent’s account not only well characterizes the multifaceted causality in academic publishing but also provides a methodological guideline for further investigation. (shrink)

In metaphysics, there are a number of distinct but related questions about the existence of “further facts”—facts that are contingent relative to the physical structure of the universe. These include further facts about qualia, personal identity, and time. In this article I provide a sequence of examples involving computer simulations, ranging from one in which the protagonist can clearly conclude such further facts exist to one that describes our own condition. This raises the question of where along the sequence the (...) protagonist stops being able to soundly conclude that further facts exist. (shrink)

In recent years, many philosophers and scientists have argued or accepted that it is impossible to learn primitive sensory concepts like “blue” and “red”. This paper defends a more qualified picture. I try to show that some received characterisations of “learning” are nonequivalent and point towards different learning-nonlearning distinctions. And, on some ways of specifying such a distinction, it might be correct that we do not and cannot “learn” a concept of blue. But on other ways of specifying such a (...) distinction, we can and do sometimes “learn” a concept of blue from experiences of blue. The latter part of the argument connects with some traditional “abstractionist” views, and I defend the present claims in view of some widely circulated concerns about “abstracting” concepts from experience. I close with some reflections on how one might, in view of all this, think about “the learning-nonlearning distinction”. (shrink)
