The Trek Separation Theorem states necessary and sufficient conditions for a linear directed acyclic graphical model to entail for all possible values of its linear coefficients that the rank of various sub-matrices of the covariance matrix is less than or equal to n, for any given n. In this paper, I extend the Trek Separation Theorem in two ways: I prove that the same necessary and sufficient conditions apply even when the generating model is partially non-linear and contains some cycles. (...) This justifies application of constraint-based causal search algorithms to data generated by a wider class of causal models that may contain non-linear and cyclic relations among the latent variables.

Popper’s original definition of truthlikeness relied on a central insight: that truthlikeness combines truth and information, in the sense that a proposition is closer to the truth the more true consequences and the less false consequences it entails. As intuitively compelling as this definition may be, it is untenable, as proved long ago; still, one can arguably rely on Popper’s intuition to provide an adequate account of truthlikeness. To this aim, we mobilize some classical work on partial entailment (...) in defining a new measure of truthlikeness which satisfies a number of desiderata. The resulting account has some interesting and surprising connections with other accounts on the market, thus shedding new light on current attempts of systematizing different approaches to verisimilitude.

This paper explores allowing truth value assignments to be undetermined or "partial" and overdetermined or "inconsistent", thus returning to an investigation of the four-valued semantics that I initiated in the sixties. I examine some natural consequence relations and show how they are related to existing logics, including ukasiewicz's three-valued logic, Kleene's three-valued logic, Anderson and Belnap's relevant entailments, Priest's "Logic of Paradox", and the first-degree fragment of the Dunn-McCall system "R-mingle". None of these systems have nested implications, and I (...) investigate twelve natural extensions containing nested implications, all of which can be viewed as coming from natural variations on Kripke's semantics for intuitionistic logic. Many of these logics exist antecedently in the literature, in particular Nelson 's "constructible falsity". (shrink)

In order to avoid the problems faced by standard realist analyses of the “relation” of instantiation, Baxter and, following him, Armstrong each analyze the instantiation of a universal by a particular in terms of their partial identity. I introduce two related conceptions of partial identity, one mereological and one non-mereological, both of which require at least one of the relata of the partial identity “relation” to be complex. I then introduce a second non-mereological conception of partial (...) identity, which allows for both relata to be simple. I take these three conceptions to exhaust the plausible ways of construing two entities as being partially identical. I then argue that there is no analysis (including those offered by Baxter and Armstrong) of a universal and a particular as being partially identical consistent with any of these three conceptions that (i) is coherent, (ii) is consistently realist, (iii) does not lead to absurd consequences, and (iv) offers a “solution” to the problem of instantiation that avoids the problems with the other standard realist responses. In so arguing, I offer a criticism of the analysis of instantiation as partial identity that is independent of the standard criticism that it entails the necessity of predication. (shrink)

Permissivism is the view that sometimes an agent's total evidential state entails both that she is epistemically permitted to believe that P and that she is epistemically permitted to believe that Q, where P and Q are contradictories. Uniqueness is the denial of Permissivism. Permissivism has recently come under attack on several fronts. If these attacks are successful, then we may be forced to accept an unwelcome asymmetry between epistemic and practical rationality. In this essay I clarify the debate by (...) distinguishing two versions of Permissiveness and Uniqueness. I then respond to several recent challenges to Permissivism in an attempt to even the score between Permissivism and Uniqueness. I will also respond to a worry – arising out of my discussion – that a defense of Permissivism itself introduces an unwelcome asymmetry between epistemic and practical rationality. (shrink)

The author contests the claim made independently by F.M. Kamm and Thomas Hurka that combatants ought to assign greater weight to collateral harm done to their compatriot noncombatants then they assign to collateral harm done to enemy non-combatants. Two arguments by analogy offered in support of such partiality, one of which appeals to permissible self/other asymmetry in cases of harming the few to save the many, and the second of which appeals to parents' justifiable partiality to their children, are found (...) wanting. The author also rebuts Kamm's argument that combatants should assign greater weight to collateral harm done to neutrals than to compatriot non-combatants. However, he contends that in some cases a neutral state's right to sovereignty may entail that a combatant ought to choose the act that will collaterally kill a greater number of compatriot non-combatants over one that involves collaterally killing a lesser number of neutrals.

Rejuvenation of cells by reprogramming toward the pluripotent state raises increasing attention. In fact, generation of induced pluripotent stem cells (iPSCs) completely reverses age‐associated molecular features, including elongation of telomeres, resetting of epigenetic clocks and age‐associated transcriptomic changes, and even evasion of replicative senescence. However, reprogramming into iPSCs also entails complete de‐differentiation with loss of cellular identity, as well as the risk of teratoma formation in anti‐ageing treatment paradigms. Recent studies indicate that partial reprogramming by limited exposure to reprogramming (...) factors can reset epigenetic ageing clocks while maintaining cellular identity. So far, there is no commonly accepted definition of partial reprogramming, which is alternatively called interrupted reprogramming, and it remains to be elucidated how the process can be controlled and if it resembles a stable intermediate state. In this review, we discuss if the rejuvenation program can be uncoupled from the pluripotency program or if ageing and cell fate determination are inextricably linked. Alternative rejuvenation approaches with reprogramming into a pluripotent state, partial reprogramming, transdifferentiation, and the possibility of selective resetting of cellular clocks are also discussed.

I argue that plausible claims in the logic of partial grounding, when combined with a plausible analysis of that concept, entail the falsity of plausible grounding claims. As our account of the concept of partial grounding and its logic should be consistent with plausible grounding claims, this is problematic. The argument hinges on the idea that some facts about what grounds what are grounded in others, which is an idea the paper aims to motivate.

Summary Critics have said that Kuhn's account of scientific revolutions represents them as subjective and irrational processes, in which mystical conversions and community pressures rather than good reasons determine choices between theories. Kuhn rejects the charge, insisting that there is partial communication among proponents of competing paradigm candidates and their arguments are rational though not coercive. The critics reply that in fact Kuhn's position entails total non-communication and irrationality. A Kuhnian account of partial communication is thus necessary. Kuhn's (...) attempt to give one, based on the notion that the good reasons advanced in paradigm debates function asvalues, fails. But a more satisfactory account can be given if it is recognized that paradigm-debaters will, in one or both of two ways, share paradigmsother than the ones at issue. Further, Kuhn's position both should and can accommodate a notion of theory reduction; his unqualified rejection of reduction is an unnecessary weakness, even apart from questions about the rationality of revolutions. The paper concludes with a brief examination of the contrast between Kuhn's and Feyerabend's strategies for the advancement of science. (shrink)

Bypassing Lewis’ Triviality Results. A Kripke-Style Partial Semantics for Compounds of Adams’ Conditionals Alberto Mura University of Sassari Abstract According to Lewis’ Triviality Results (LTR), conditionals cannot satisfy the equa­tion (E) P(C if A) = P(C | A), except in trivial cases. Ernst Adams (1975), however, provided a probabilistic semantics for the so-called simple conditionals that also sat­isfies equation (E) and provides a probabilistic counterpart of logical consequence (called p-entailment). Adams’ probabilistic semantics is coextensive to Stalnaker­Thomason’s (1970) and (...) Lewis’ (1973) semantics as far as simple conditionals are concerned. A theorem, proved in McGee 1981, shows that no truth-functional many-valued logic allows a relation of logical consequence coextensive with Adams’ p-entailment. This paper presents a modified modal (Kripke-style) version of de Finetti’s se­mantics that escapes McGee’s result and provides a general truth-conditional se­mantics for indicative conditionals. It agrees with Adams’ logic and is not affected by LTR. The new framework encompasses and extends Adams’ probabilistic se­mantics (APS) to compounds of conditionals. A generalised set of axioms for prob­ability over the set of tri-events is provided, which coincide with the standard axioms over the set of the two-valued ordinary sentences. -/- Keywords: Conditionals, Probability logic, de Finetti, Tri-events, Adams’ logic, Stal­naker’s thesis, Partial logic, Lewis’ triviality results, Ramsey test.

Are countries especially entitled, if not obliged, to prioritize the interests or well-being of their own citizens during a global crisis, such as a global pandemic? We call this partiality for compatriots in times of crisis “crisis nationalism”. Vaccine nationalism is one vivid example of crisis nationalism during the COVID-19 pandemic; so is the case of the US government’s purchasing a 3-month supply of the global stock of the antiviral Remdesivir for domestic use. Is crisis nationalism justifiable at all, and, (...) if it is, what are its limits? We examine some plausible arguments for national partiality, and conclude that these arguments support crisis nationalism only within strict limits. The different arguments for partiality, as we will note, arrive at these limits for different reasons. But more generally, so we argue, any defensible crisis nationalism must not entail the violation of human rights or the worsening of people’s deprivation. Moreover, we propose that good faith crisis nationalism ought to be sensitive to the potential moral costs of national partiality during a global crisis and must take extra care to control or offset these costs. Thus, crisis nationalism in the form of vaccine nationalism or the hoarding of global supplies of therapeutics during a global pandemic exceeds the bounds of acceptable partiality. (shrink)

It is plausible to think that practices of caring are partly constituted by a caregiver's commitment to a cared-for. However, discussions of caring often contain no explicit discussion of such commitments, and do not attempt to draw any philosophical conclusions from the nature of caring relations as committed. A discussion of caring practices that emphasizes the importance of commitment therefore has the potential to generate important new insights for our understanding of caring. This essay begins that project by arguing that (...) a commitment-centric conception of caring entails the truth of moral partialism. Although many care-ethicists are sympathetic to partialism, the arguments in its defense remain controversial. As I show in this article, however, partialism is necessarily true given the committed nature of caring. This is because the concept of commitment is itself a necessarily partial one: to say that we are equally committed to everyone or everything is equivalent to saying that we are not committed to anything. Thus, when viewed as a species of commitment, it is part of the concept of caring that it requires us to put the needs of those we care for before the needs of those unknown to us. (shrink)

In the literature on mereology it is often accepted that mereological universalism entails extensionalism. More precisely, many accept that, if parthood is assumed to be a partial order, the thesis that every plurality of entities has a mereological fusion entails the thesis that different composite entities have different proper parts. Central to this idea is the principle known as ‘Weak Supplementation’ which many take to impose an important constraint on the relation of proper parthood. In this paper I argue (...) that this claim is false as the principle that I will call ‘Minimal Supplementation’ appears to be capable of doing all the work done by Weak Supplementation but without entailing extensionalism if conjoined with universalism and core mereology.

This article presents a catalogue of some of the ways in which Proust's novel fails to make sense. The major categories of non-sense examined here are: minor inconsistencies due to the unfinished quality of the work; chronological incoherences; and inconsistent distinctions between narrator and author, with particular attention to textual entailments of the differences between the author and his semi-autobiographical narrator in terms of homosexuality, Jewishness and snobbery.

Both syntactic and semantic solutions are given for the entailment problem of duality theory. The test algebra theorem provides both a syntactic solution to the entailment problem in terms of primitive positive formulae and a new derivation of the corresponding result in clone theory, viz. the syntactic description of $\operatorname{Inv(Pol}(R))$ for a given set R of finitary relations on a finite set. The semantic solution to the entailment problem follows from the syntactic one, or can be given (...) in the form of an algorithm. It shows, in the special case of a purely relational type, that duality-theoretic entailment is describable in terms of five constructs, namely trivial relations, intersection, repetition removal, product, and retractive projection. All except the last are concrete, in the sense that they are described by a quantifier-free formula. It is proved that if the finite algebra $\underline{M}$ generates a congruence-distributive variety and all subalgebras of $\underline{M}$ are subdirectly irreducible, then concrete constructs suffice to describe entailment. The concept of entailment appropriate to strong dualities is also introduced, and described in terms of coordinate projections, restriction of domains, and composition of partial functions. (shrink)

If semantic consequence is analyzed with extensive games, logical reasoning can be accounted for by looking at how players solve entailment games. However, earlier approaches to game semantics cannot achieve this reduction, by want of explicitly dened preferences for players. Moreover, although entailment games can naturally translate the idea of argumentation about a common ground, a cognitive interpretation is undermined by the complexity of strategic reasoning. We thus describe a class of semantic extensive entailment game with algorithmic (...) players, who have preferences for parsimonious spending of computational resources and thus compute partial strategies under qualitative uncertainty about future histories. We prove the existence of local preferences for moves and of strategic fixpoints that allow to map game-trees to tableaux proofs, and exhibit a strategy prole that solves the fixpoint selection problem, and can be mapped to systematic constructions of semantic trees, yielding a completeness result by translation. We then discuss the correspondence between proof heuristics and strategies in our games, the relations of our games to gts, and possible extensions to other entailment relations. We conclude that the main interest of our result lies in the possibility to bridge argumentative and cognitive models of logical reasoning, rather than in new meta-theoretic results. All proofs are given in appendix. (shrink)

The essence of the meaning of a declarative sentence is given by stating its truth conditions, and consequently semantics, the study of meaning, must include a theory of truth conditions. Such a theory must not only describe accurately the truth conditions of declarative sentences, it must also answer the question of when two sentences have the same truth conditions. The fundamental semantic relation of having the same truth conditions cannot be ignored by any reasonable theory.This paper is an attempt to (...) find a partial account of this relation by using game theoretical semantics as developed by Hintikka and his followers. The account given will establish a connection between this approach to semantics and the theory of firstdegree entailment formulated by Anderson and Belnap. (shrink)

Ruling Passions is Simon Blackburn’s latest attempt to defend a theory of practical reason which he calls “expressivism”.2 In the first three chapters Blackburn outlines an account of how we should understand statements of right, good and virtue, as well as their negative counterparts (“the Ethical [or Moral] Proposition”, as he terms this amalgam). This he calls “quasi-realism”. I shall describe what this position entails in the first section. Secondly I shall consider the opposition to this view advanced by McDowell (...) (1987), who in turn takes his inspiration from Wiggins (1976a, 1976b). Finally I shall assess Blackburn’s reply to McDowell and Wiggins (found in Chapter 4 of RP), and argue that it is inadequate.

A rather promising value theory for environmental philosophers combines the well-known fitting attitude (FA) account of value with the rather less well-known account of value as richness. If the value of an entity is proportional to its degree of richness (which has been cashed out in terms of unified complexity and organic unity), then since natural entities, such as species or ecosystems, exhibit varying degrees of richness quite independently of what we happen to feel about them, they also possess differing (...) degrees of mind-independent and subject-independent value. In particular, their value is not dependent on the desires or preferences of humans. The fitting attitudes account of value, at least as it is standardly developed, demands isomorphic evaluative responses on the part of all valuers. In particular, it entails that all valuers should have isomorphic preferences. But this seems absurd. I consider three different strategies with which the fitting attitude theorist can deflect this challenge. The first makes use of an account of non-standard value relations in terms of permissible preference orderings. The second appeals to value appearances and the associated notions of value distance and value perspective. The third involves an account of the ultimate bearers of value as properties, rather than as propositions or states of affairs. These strategies are not all mutually incompatible. While it isn’t possible to combine the first and second strategies, it is possible to combine the first and third strategies, and also to combine the second and the third. (shrink)

The paper builds on both a simply typed term system ${\cal PR}^\omega$ and a computation model on Scott domains via so-called parallel typed while programs (PTWP). The former provides a notion of partial primitive recursive functional on Scott domains $D_\rho$ supporting a suitable concept of parallelism. Computability on Scott domains seems to entail that Kleene's schema of higher type simultaneous course-of-values recursion (scvr) is not reducible to partial primitive recursion. So extensions ${\cal PR}^{\omega e}$ and PTWP $^e$ are (...) studied that are closed under scvr. The twist are certain type 1 Gödel recursors ${\cal R}_k$ for simultaneous partial primitive recursion. Formally, ${\cal R}_k\vec{g}\vec{H}xi$ denotes a function $f_i \in D_{\iota\to\iota}$ , however, ${\cal R}_k$ is modelled such that $f_i$ is finite, or in other words, a partial sequence. As for PTWP $^e$ , the concept of type $\iota\to\iota$ writable variables is introduced, providing the possibility of creating and manipulating partial sequences. It is shown that the PTWP $^e$ -computable functionals coincide with those definable in ${\cal PR}^{\omega e}$ plus a constant for sequential minimisation. In particular, the functionals definable in ${\cal PR}^{\omega e}$ denoted ${\cal R}^{\omega e}$ can be characterised by a subclass of PTWP $^e$ -computable functionals denoted ${\rm PPR}^{\omega e}$ . Moreover, hierarchies of strictly increasing classes ${\cal R}^{\omega e}_n$ in the style of Heinermann and complexity classes ${\rm PPR}^{\omega e}_n$ are introduced such that $\forall n\ge 0. {\cal R}^{\omega e}_n ={\rm PPR}^{\omega e}_n$ . These results extend those for ${\cal PR}^\omega$ and PTWP [Nig94]. Finally, scvr is employed to define for each type $\sigma$ the enumeration functional $E^\sigma$ of all finite elements of $D_\sigma$. (shrink)

Bayesian confirmation theory is rife with confirmation measures. Many of them differ from each other in important respects. It turns out, though, that all the standard confirmation measures in the literature run counter to the so-called “Reverse Matthew Effect” (“RME” for short). Suppose, to illustrate, that H1 and H2 are equally successful in predicting E in that p(E | H1)/p(E) = p(E | H2)/p(E) > 1. Suppose, further, that initially H1 is less probable than H2 in that p(H1) < p(H2). (...) Then by RME it follows that the degree to which E confirms H1 is greater than the degree to which it confirms H2. But by all the standard confirmation measures in the literature, in contrast, it follows that the degree to which E confirms H1 is less than or equal to the degree to which it confirms H2. It might seem, then, that RME should be rejected as implausible. Festa (2012), however, argues that there are scientific contexts in which RME holds. If Festa’s argument is sound, it follows that there are scientific contexts in which none of the standard confirmation measures in the literature is adequate. Festa’s argument is thus interesting, important, and deserving of careful examination. I consider five distinct respects in which E can be related to H, use them to construct five distinct ways of understanding confirmation measures, which I call “Increase in Probability”, “Partial Dependence”, “Partial Entailment”, “Partial Discrimination”, and “Popper Corroboration”, and argue that each such way runs counter to RME. The result is that it is not at all clear that there is a place in Bayesian confirmation theory for RME. (shrink)

The paper builds on a simply typed term system ${\cal PR}^\omega $ providing a notion of partial primitive recursive functional on arbitrary Scott domains $D_\sigma$ that includes a suitable concept of parallelism. Computability on the partial continuous functionals seems to entail that Kleene's schema of higher type simultaneous course-of-values recursion (SCVR) is not reducible to partial primitive recursion. So an extension ${\cal PR}^{\omega e}$ is studied that is closed under SCVR and yet stays within the realm of (...) subrecursiveness. The twist are certain type 1 Gödel recursors ${\cal R}_k$ for simultaneous partial primitive recursion. Formally, the value ${\cal R}_k\vec{g}\vec{H} x i$ is a function $f_i$ of type $\iota \to \iota$ , however, ${\cal R}_k$ is modelled such that $f_i$ is a finite element of $D_{\iota\to\iota}$ or in other words, a partial sequence. It is shown that the Ackermann function is not definable in ${\cal PR}^{\omega e}$. (shrink)

It has been shown in Spirtes(1995) that X and Y are d-separated given Z in a directed graph associated with a recursive or non-recursive linear model without correlated errors if and only if the model entails that ρXY.Z = 0. This result cannot be directly applied to a linear model with correlated errors, however, because the standard graphical representation of a linear model with correlated errors is not a directed graph. The main result of this paper is to show how (...) to associate a directed graph with a linear model L with correlated errors, and then use d-separation in the associated directed graph to determine whether L entails that a particular partial correlation is zero.

In this chapter I defend the mind-blindness theory of autism, by showing how it can accommodate data which might otherwise appear problematic for it. Specifically, I show how it can explain the fact that autistic children rarely engage in spontaneous pretend-play, and also how it can explain the executive-function deficits which are characteristic of the syndrome. I do this by emphasising what I take to be an entailment of the mind-blindness theory, that autistic subjects have difficulties of access to (...) their own mental states, as well as to the mental states of other people.

The potential for jointly using or integrating Western science and indigenous knowledge, especially in such fields as environmental management, is a hotly debated topic nowadays. However, the difficulties involved in such a task are not always fully understood and co-management experiences achieved only partially the expected outcomes. In this contribution, I show how a sound combination of the two bodies of knowledge would be possible only if there is a way to accommodate different interpretations of reality and knowledge criteria. The (...) issue should then be faced at the epistemological level too, discussing the possibility and implications of a genuine epistemic pluralism. With reference, among others, to Feyerabend’s later writings, here I illustrate some possible insights for addressing the matter that a Western perspectivist stance could provide. (shrink)

Luck egalitarians equalize the outcome enjoyed by people who exemplify the same degree of distributive desert by removing the influence of luck. They also try to calibrate differential rewards according to the pattern of distributive desert. This entails that they have to decide upon, among other things, the rate of reward, i.e., a principled way of distributing rewards to groups exercising different degrees of the relevant desert. However, the problem of the choice of reward principle is a relatively and undeservedly (...) neglected issue among luck egalitarians. The main goal of this paper is to highlight the importance and difficulty of this problem, and to elaborate upon G. A. Cohen's community-oriented response to it. In the last section, I provide a taxonomy of distributive pluralism, contrasting Cohen’s view with other (not so genuine) pluralisms - especially with all-things-considered varieties - while trying to motivate readers to adopt the more robust form of pluralism.

Any inferential system in which the addition of new premises can lead to the retraction of previous conclusions is a non-monotonic logic. Classical conditional probability provides the oldest and most widely respected example of non-monotonic inference. This paper presents a semantic theory for a unified approach to qualitative and quantitative non-monotonic logic. The qualitative logic is unlike most other non- monotonic logics developed for AI systems. It is closely related to classical (i.e., Bayesian) probability theory. The semantic theory for qualitative (...) non-monotonic entailments extends in a straightforward way to a semantic theory for quantitative partial entailment relations, and these relations turn out to be the classical probability functions.

This paper gives an explication of our intuitive notion of strength of justification in a controversial debate. It defines a thesis' degree of justification within the bipolar argumentation framework of the theory of dialectical structures as the ratio of coherently adoptable positions according to which that thesis is true over all coherently adoptable positions. Broadening this definition, the notion of conditional degree of justification, i.e.\ degree of partial entailment, is introduced. Thus defined degrees of justification correspond to our (...) pre-theoretic intuitions in the sense that supporting and defending a thesis t increases, whereas attacking it decreases, t's degree of justification. Moreover, it is shown that (conditional) degrees of justification are (conditional) probabilities. Eventually, the paper explains that it is rational to believe theses with a high degree of justification insofar as this strengthens the robustness of one's position. (shrink)

That a philosophical thesis entails a vicious regress is commonly taken to be decisive evidence that the thesis is false. In this paper, I argue that the existence of a vicious regress is insufficient to reject a proposed analysis provided that certain constraints on the analysis are met. When a vicious regress is present, some further consequence of the thesis must be established that, together with the presence of the vicious regress, shows the thesis to be false. The argument is (...) provided largely through the examination of Michael Bergmann's vicious regress argument against strong awareness internalism and a partial defense of that thesis against Bergmann.

This article takes issue with two prominent views in the current debate around epistemic partiality in friendship. Strong views of epistemic partiality hold that friendship may require biased beliefs in direct conflict with epistemic norms. Weak views hold that friendship may place normative expectations on belief formation but in a manner that does not violate these norms. It is argued that neither view succeeds in explaining the relationship between epistemic norms and friendship norms. Weak views inadvertently endorse a form of (...) motivated reasoning, failing to resolve the normative clash they seek to avoid. Strong views turn out to be incoherent once we consider the question of whether the requirement to form an epistemically partial belief is independent of whether the belief in question would be true. It is then argued that an epistemology of friendship should recognise the special role that understanding plays in friendship. On this view, friendship normatively requires understanding the truth about our friends. This entails that epistemic partiality, far from being a requirement, is in fact at odds with good friendship.

Liberal nationalism is a boundary‐making project, and a feature of this boundary‐making enterprise is the belief that the compatriots have a certain priority over strangers. For this reason it is often thought that liberal nationalism cannot be compatible with the demands of global egalitarianism. In this essay, I examine the sense in which liberal nationalism privileges compatriots, and I argue that, properly understood, the idea of partiality for compatriots in the context of liberal nationalism is not at odds with global (...) equal concern for all persons. In particular, I argue that the three central goals and aspirations of liberal nationalism—promoting individual autonomy and cultural identity, the realization of deliberative democracy, and the aspiration for social justice within the state—do not entail or require a form of compatriot partiality that is inconsistent with the demands of global egalitarian justice.

The 1979 partial nuclear reactor meltdown at Three Mile Island was simultaneously hyper-visible and hidden from public view. It was the subject of non-stop media attention, but its causes and consequences required expert explanation. No fire or explosion marked the moment when insensible radionuclides escaped the facility. Yet, residents recalled a variety of troubling sights, sounds, odors, tastes, and sensations. Public distrust percolated in the interstices between government assertions that little radiation had escaped the facility and residents’ sense memories (...) of the incident. This article traces intertwined networks of activists from Japan and Pennsylvania as they mobilized legally, politically, and scientifically to develop evidence about the offsite effects of Three Mile Island. Exploring the distinct cosmology of evidence that activists marshaled, the article shows how they placed the messy, contingent, dynamic living world at the center of inquiries about the meltdown’s consequences. Activists developed new practices of biological witness that reconfigured the interplay between scientific, legal, and moral authority, while concurrently reformulating sufferers’ subjectivities and notions of scientific objectivity. In the process, they suggested that environmental justice entailed epistemic justice. Their cosmology of evidence served as an argument and a material proof that the beloved but suffering living world, and the sciences used to understand it, could and should frame the governance of industrial society’s invisible harms.

The aim of this study is to address the “Grounding Grounding Problem,” that is, the question as to what, if anything, grounds facts about grounding. I aim to show that, if a seemingly plausible principle of modal recombination between fundamental facts and the principle customarily called “Entailment” are assumed, it is possible to prove not only that grounding facts featuring fundamental, contingent grounds are derivative but also that either they are partially grounded in the grounds they feature or they (...) are “abysses”.

This paper presents an information-based logic that is applied to the analysis of entailment, implicature and presupposition in natural language. The logic is very fine-grained and is able to make distinctions that are outside the scope of classical logic. It is independently motivated by certain properties of natural human reasoning, namely partiality, paraconsistency, relevance, and defeasibility: once these are accounted for, the data on implicature and presupposition comes quite naturally.The logic is based on the family of semantic spaces known (...) as bilattices, originally proposed by Ginsberg (1988), and used extensively by Fitting (1989, 1992). Specifically, the logic is based on a subset of bilattices that I call evidential bilattices, constructed as the Cartesian product of certain algebras with themselves. The specific details of the epistemic agent approach of the logical system is derived from the work of Belnap (1975, 1977), augmented by the use of evidential links for inferencing. An important property of the system is that it has been implemented using an extension of Fitting's work on bilattice logic programming (1989, 1991) to build a model-based inference engine for the augmented Belnap logic. This theorem prover is very efficient for a reasonably wide range of inferences. (shrink)

In this article, we propose a new account concerning the interlock between intentions and motor representations (henceforth: MRs), showing that the interface problem is not as deep as previously proposed. Before discussing our view, in the first section we report the ideas developed in the literature by those who have tried to solve this puzzle before us. The article proceeds as follows. In Sections 2 and 3, we address the views by Butterfill and Sinigaglia, and Mylopoulos and Pacherie, respectively, and (...) argue that both solutions entail a translation between representational formats, which both accounts aim to avoid. In Section 4, we present our brand‐new claim, according to which intentions and MRs partially share the same motor format, inasmuch as executable action concepts are naturally represented in the agent's motor system together with the action's outcomes. Indeed, since intentions are constituted by executable action concepts and since there is evidence that action concepts are represented (and, thus, built) in the same motor format as action outcomes, the interlock between intentions and MRs no longer constitutes a problem. Then, in Section 5, we report empirical evidence in support of our claim, and before concluding, in Section 6 we briefly clarify our relations with two very recent accounts that criticized the proposals by Mylopoulos and Pacherie and Butterfill and Sinigaglia: Shepherd's and Burnston's. Finally, in Section 7, we offer some remarks about the philosophical idea defended here. The basic insight is that interface without translation is possible because action concepts are such stuff as MRs are made on. (shrink)

This paper argues for a comprehensive conception of empathy as comprising epistemic, affective, and motivational elements and introduces the ancient Stoic theory of attachment (Greek,oikeiōsis) as a model for describing the embodied, emotional response to others that we take to be distinctive of empathy. Our argument entails that in order to provide a suitable conceptual framework for the interdisciplinary study of empathy one must extend the scope of recent “simulationalist” and “enactivist” accounts of empathy in two important respects. First, against (...) the enactivist assumption that human mindreading capacities primarily rely on an immediate, quasi-perceptual understanding of other’s intentional states, we draw on Alfred Schutz’ analysis of social understanding to argue that reflective types of understanding play a distinct, but equally fundamental role in empathic engagements. Second, we insist that empathy also involves an affective response toward the other and their situation (as the empathizer perceives this). We suggest analyzing this response in terms of the Stoic concepts of attachment, concern, and a fundamental type of prosocial motivation, that can best be described as an “extended partiality.” By way of conclusion, we integrate the above concepts into a comprehensive conceptual framework for the study of empathy and briefly relate them to current debates about empathic perception and prosocial motivation. The result, we argue, is an account that stays neutral with regard to the exact nature of the processes involved in producing empathy and can therefore accommodate discussion across theoretical divides—e.g., those between enactivist, simulationalist, and so-called theory-theorist approaches.

The power to exercise control is a crucial feature of agency. Necessarily, if S cannot exercise some degree of control over anything - any state of affairs, event, process, object, or whatever - S is not an agent. If S is not an agent, S cannot act intentionally, responsibly, or rationally, nor can S possess or exercise free will. In my dissertation I reflect on the nature of control, and on the roles consciousness plays in its exercise. I first consider (...) the fragmented state of philosophical and empirical work on control. I argue that a mature philosophy of agency stands in need of a detailed personal-level account of control, and I begin by explicating a notion I call intentional control. On this explication, an agent J exercises intentional control in service of an intention X to the degree that behavior of J's for which X plays a (non-deviant) causal role approximates the representational content of X. With this explication in hand, I offer analyses of theoretically salient points along a degreed spectrum (covering, e.g., the exercise of minimal, successful, and perfect intentional control). Next, I develop an account of the degrees of intentional control's possession. This involves elucidation of ingredients of intentional control, i.e. those features of agents and environments that constitute an agent's causal potency and skill. It turns out that an agent's possession of control regarding an intention is intimately tied to her ability to repeatedly execute that intention across some specified (hypothetical) set of scenarios. Finally, I discuss a number of potentially fruitful applications of the account. In chapter three I confront a strong intuition, persistent in both philosophy and cognitive science, that consciousness is somehow intimately involved in the exercise of control. In this connection recent empirical work indicates the causal powers of consciousness remain poorly understood. I argue that Functional Agnosticism - the view that any claim regarding a function of consciousness for behavior is currently underdetermined by the data - is the wisest position on the causal powers of consciousness. Recognition of this unsatisfying state of affairs motivates reflection on what might enable progress beyond it. I argue that establishing a causal function for consciousness is facilitated by clarity on several issues. First, what is the sense of consciousness at issue? I isolate state consciousness, discuss the potential relevance of various types of conscious states, and distinguish between ambitious and modest approaches to the causal powers of state consciousness. In short, ambitious approaches seek to understand the causal contributions of a conscious mental state in virtue of the fact that the state is conscious; modest approaches seek to understand the causal contributions of conscious mental states, full stop. I argue that for various theoretical purposes, both approaches can be useful. Second, what is the sense of control at issue? I argue that for many important theoretical purposes, intentional control is the relevant sense. Finally, I illustrate the usefulness of clarity on these issues by examining recent work on the roles of conscious and unconscious vision for action. This work suggests that some important subset of our overt action is controlled by non-conscious processes. I apply insights developed earlier, noting common mistakes made in this literature, and highlighting important empirical possibilities these mistakes obscure. In later chapters I develop a novel account of conscious control. In chapter four I develop a central part of the account, which involves a view on the intentional structure of conscious trying. The leading view entails that conscious trying possesses a descriptive (or thetic) structure. Based on relevant empirical work concerning deafferented and paralyzed patients, I argue for the view that conscious trying is (at least) partially constituted by directive (or telic) structure. Finally, I argue that the exercise of conscious control is best understood as an exercise of intentional control for which the experience of trying plays a constitutive role. After presenting arguments for this view and defending the view against objections, I discuss the importance of conscious control for a mature philosophy of mind and agency. (shrink)

ArgumentThis paper argues that Samuel Clarke's account of agent causation (i) provides a philosophical basis for moderate voluntarism, and (ii) both leads to and benefits from the acceptance of partial occasionalism as a model of causation for material beings. Clarke's account of agent causation entails that for an agent to be properly called an agent (i.e. causally efficacious), it is essential that the agent is free to choose whether to act or not. This freedom is compatible with the existence (...) of conceptually necessary connections. Hence, Clarke can harmonize God's freedom of choosing with the existence of eternal and necessary relations among things. Moreover, in Clarke's account, only intelligent entities can be properly understood as efficacious causes. Beings deprived of intelligence are not agents or efficacious causes at all and their effects are thus the result of the immediate action of some intelligent being operating upon them. (shrink)

This paper shows that versions of prioritarianism that focus at least partially on well-being levels at certain times conflict with conventional views of prudential value and prudential rationality. So-called timeslice prioritarianism, and pluralist views that ascribe importance to timeslices, hold that a benefit matters more, the worse off the beneficiary is at the time of receiving it. We show that views that evaluate outcomes in accordance with this idea entail that an agent who delays gratification makes an outcome worse, even (...) if it is better for the agent and worse for no one else. We take this to show that timeslice prioritarianism and some pluralist views violate Weak Pareto, and we argue that these versions of prioritarianism are implausible. (shrink)

Paradefinite logics are logics that can be used for handling contradictory or partial information. As such, paradefinite logics should be both paraconsistent and paracomplete. In this paper we consider the simplest semantic framework for introducing paradefinite logics. It consists of the four-valued matrices that expand the minimal matrix which is characteristic for first degree entailments: Dunn–Belnap matrix. We survey and study the expressive power and proof theory of the most important logics that can be developed in this framework.

In this paper, I resolve a potential contradiction between two of Hume's central tenets: that complex perceptions consist of simple perceptions and that distinct things are separable. The former implies that a complex perception is not separable from its constituent simple perceptions, as a change in its constituents destroys its identity. The latter entails that the complex perception is separable from these simple perceptions, since it is distinct from them. This is a contradiction. I resolve it by appealing to a (...) third kind of distinction in addition to the two kinds Hume mentions: real distinctions and distinctions of reason. This third distinction is a partial distinction. I argue that just as the separability principle does not apply to distinctions of reason, neither does it apply to perceptions that are only partially distinct from other perceptions. Hence, the apparent contradiction is resolved. (shrink)

Scholars have addressed restrictions on individual liberty, or deprivations thereof, that do not entail prison or jail—including area restrictions, revoking driver’s licenses, and GPS bracelets. In all legal domains, the effects of these measures on the lives of targeted individuals can be significant, primarily with respect to their capability to guide their own behavior. Some are applied categorically rather than individually, do not involve a fair trial or hearing, or are applied preventively or after the targeted individual has completed a (...) prison sentence. My aim in this article is to extend our view from prison as the quintessential method of depriving individuals of their liberty to control of individuals without locking them up. I address degrees of individual liberty and inquire into legal protections for individuals who are partially free but deprived of liberty in some areas of life. (shrink)

Various authors have argued that in the future not only will it be technically feasible for human minds to be transferred to other substrates, but this will become, for most humans, the preferred option over the current biological limitations. It has even been claimed that such a scenario is inevitable in order to solve the challenging, but imperative, multi-agent value alignment problem. In all these considerations, it has been overlooked that, in order to create a suitable environment for a particular (...) mind – for example, a personal universe in a computational substrate – numerous other potentially sentient beings will have to be created. These range from non-player characters to subroutines. This article analyzes the additional suffering and mind crimes that these scenarios might entail. We offer a partial solution to reduce the suffering by imposing on the transferred mind the perception of indicators to measure potential suffering in non-player characters. This approach can be seen as implementing literal empathy through enhanced cognition. (shrink)
