This paper evaluates Jonathan Quong’s attempt to defend a version of political liberalism from the asymmetry objection. I object that Quong’s defence relies on a premise that has not been adequately supported and does not look as if it can be given adequate support.

Political liberalism offers perhaps the most developed and dominant account of justice and legitimacy in the face of disagreement among citizens. A prominent objection states that the view arbitrarily treats differently disagreement about the good, such as on what makes for a good life, and disagreement about justice. In the presence of reasonable disagreement about the good, political liberals argue that the state must be neutral, but they do not suggest a similar response given reasonable disagreement about what justice (...) requires. A leading political liberal, Jonathan Quong, has recently offered a rebuttal to this asymmetry objection. His reply rests on an innovative distinction between justificatory and foundational disagreement. Quong claims that disagreements about justice in a well ordered society are justificatory while disagreements about the good are foundational, and suggests that this fact blocks the asymmetry objection. We assess Quong's solution and argue that it fails to justify legitimate state action on matters of justice but not the good. We conclude that the asymmetry objection continues to undermine political liberalism. (shrink)

Abstract The debate about the ethics of uninhabited aerial vehicles (UAVs) is failing to keep pace with the rise of the technology. Therefore, all the key players, including ethicists, lawyers, and roboticists, are keen to offer their views on the use of these drone aircraft. Some are opposed to their use, citing a range of ethical, legal and operational issues, while others argue for their ethically mandated use. B.J. Strawser fits into this latter category. He develops a principle of ?unnecessary (...) risk?, from which he argues that we have an ethical obligation to employ UAVs if we can do so without incurring a loss of capability. Strawser defends his argument against a number of potential objections, most questionably, the argument that the use of distance weaponry such as drones, against another state without distance weaponry, crosses some moral threshold that makes the combat immoral. Utilising Jeff McMahan's work on the inequality of combatants, Strawser essentially argues that there are no grounds for a ?fair fight?. However, this paper will argue that it is not so easy to overturn the doctrine of the moral equality of combatants, nor dismiss the problem with asymmetry. It will demonstrate that if the asymmetry reaches a certain level, the justification for resorting to war may be removed and some sort of policing action may remain the only option. (shrink)

This article seeks to make two significant contributions to the debate surrounding the asymmetry objection to political liberalism. The first is to distinguish between and explicate moderate and radical versions of the asymmetry objection as two discrete forms that this criticism can take. The second contribution is to defend the radical version of the asymmetry objection as a serious challenge to political liberalism. It does this by arguing that the commitment to reciprocity that underpins (...) the principle of legitimacy can be the subject of reasonable disagreement, which therefore undermines the asymmetry central to political liberalism between the legitimacy of being able to coerce compliance with principles of right but not principles of the good on the grounds that the latter can be the subject of reasonable disagreement whereas the former cannot.

Reasonable people disagree deeply about the nature of the good life. But reasonable people also disagree fundamentally about principles of justice. If this is true, then why does political liberalism permit the state to act on reasons of justice, but not for reasons grounded in conceptions of the good life? There appears to be an indefensible asymmetry in the way political liberalism treats disagreements about justice and disagreements about the good life. This is the asymmetry objection to (...) political liberalism. The principal aim of this article is to show that the asymmetry objection can be refuted. This is done by drawing a distinction between two different types of reasonable disagreement that can occur between citizens. The first type is foundational disagreement . Disagreements of this type are characterized by the fact that the participants do not share any premises which can serve as a mutually acceptable standard of justification. The second type of disagreement, justificatory disagreement , occurs when participants do share premises that serve as a mutually acceptable standard of justification, but they nevertheless disagree about certain substantive conclusions. Making this distinction allows me to show why political liberalism’s asymmetric treatment of justice and the good life is both defensible and desirable. Key Words: John Rawls • perfectionism • political liberalism • public reason • reasonable pluralism. (shrink)

According to asymmetric comparativism, it is worse for a person to exist with a miserable life than not to exist, but it is not better for a person to exist with a happy life than not to exist. My aim in this paper is to explain how asymmetric comparativism could possibly be true. My account of asymmetric comparativism begins with a different asymmetry, regarding the (dis)value of early death. I offer an account of this early death asymmetry, appealing (...) to the idea of conditional goods, and generalize it to explain how asymmetric comparativism could possibly be true. I also address the objection that asymmetric comparativism has unacceptably antinatalist implications. (shrink)

While the fundamental laws of physics are time-reversal invariant, most macroscopic processes are irreversible. Given that the fundamental laws are taken to underpin all other processes, how can the fundamental time-symmetry be reconciled with the asymmetry manifest elsewhere? In statistical mechanics, progress can be made with this question. What I dub the ‘Zwanzig–Zeh–Wallace framework’ can be used to construct the irreversible equations of SM from the underlying microdynamics. Yet this framework uses coarse-graining, a procedure that has faced much criticism. (...) I focus on two objections in the literature: claims that coarse-graining makes time-asymmetry ‘illusory’ and ‘anthropocentric’. I argue that these objections arise from an unsatisfactory justification of coarse-graining prevalent in the literature, rather than from coarse-graining itself. This justification relies on the idea of measurement imprecision. By considering the role that abstraction and autonomy play, I provide an alternative justification and offer replies to the illusory and anthropocentric objections. Finally, I consider the broader consequences of this alternative justification: the connection to debates about inter-theoretic reduction and the implication that the time-asymmetry in SM is weakly emergent. 1Introduction 1.1Prospectus2The Zwanzig–Zeh–Wallace Framework3Why Does This Method Work? 3.1The special conditions account3.2When is a density forwards-compatible?4Anthropocentrism and Illusion: Two Objections 4.1The two objections in more detail4.2Against the justification by measurement imprecision5An Alternative Justification 5.1Abstraction and autonomy5.2An illustration: the Game of Life6Reply to Illusory7Reply to Anthropocentric8The Wider Landscape: Concluding Remarks 8.1Inter-theoretic relations8.2The nature of irreversibility.

In 2019, several US states passed “heartbeat” bills. Should such bills go into effect, they would outlaw abortion once an embryonic heartbeat can be detected, thereby severely limiting an individual’s access to abortion. Many states allow health care professionals to refuse to provide an abortion for reasons of conscience. Yet heartbeat bills do not include a positive conscience clause that would allow health care professionals to provide an abortion for reasons of conscience. I argue that this asymmetry is unjustified. (...) The same criteria that justify protecting conscientious refusals to provide abortion also justify protecting positive conscientious appeals regarding abortion. Thus, if the law provides legal exemptions for health care professionals who, as a matter of conscience, refuse to provide abortions where it is legal, it should also provide exemptions for health care professionals who, as a matter of conscience, feel obligated to provide abortions where it is illegal.

This paper examines a recent attempt by Evan Jobe to account for the asymmetric character of many scientific explanations. It is argued that a purported counterexample to Jobe's account, from Clark Glymour, is inconclusive, but that the account faces independent objections. It is also suggested, contrary to Jobe, that the explanatory relation is not always asymmetric. Sometimes a singular sentence C can figure in a DN derivation of another singular sentence E and E can also figure in a DN derivation (...) of C. Yet while we are inclined to regard the first derivation as an explanation of E, we are not inclined to regard the second derivation as an explanation of C. As Sylvain Bromberger pointed out in a now classic article (1966), one can explain the period of a pendulum by reference to its length and yet, although one can give a DN derivation of the length of a pendulum by reference to its period, this derivation does not seem to represent an explanation. Evan Jobe has recently offered an interesting account of such explanatory asymmetries and Clark Glymour has in turn proposed a counterexample which seems to show that Jobe's account is defective. The aim of this paper is two-fold. I shall attempt to show that (a) Glymour's proposed counterexample can be rejected on the grounds that it violates an independently plausible restriction on the role that equalities may play in DN explanation, and that (b) although Glymour's counterexample can be avoided in this way, Jobe's account is defective in several other respects.

A peer commentary on an AJOB article by Kyle Fritz called "Unjustified Asymmetry: Positive Claims of Conscience and Heartbeat Bills.".

The unificationist theory of causal explanation offers a theory of causation and explanation with no causal primitives. Kitcher proposed that it offered an account of explanatory asymmetry, but his proposal has been criticized for being too dependent on contingent facts and surreptitiously supposing causal realism. In addition, critics have argued that unificationism cannot account for asymmetry in a world with symmetric laws of physics and is lead to accept backwards explanation in certain epistemic situations. Unificationism has been defended (...) from some of these objections. We critique those defenses, rejecting some and developing others, as well as adding new ones. In doing so, we argue that objectors are wrong to treat explanatory asymmetry as an a priori matter and that unificationism is appropriately sensitive to the right sort of empirical facts. (shrink)

Strong dispositional monism, the position that all fundamental physical properties consist in dispositional relations to other properties, is naturally construed as property structuralism. J. Lowe’s circularity/regress objection constitutes a serious challenge to SDM that questions the possibility of a purely relational determination of all property essences. The supervenience thesis of A. Bird’s graph-theoretic asymmetry reply to CRO can be rigorously proved. Yet the reply fails metaphysically, because it reveals neither a metaphysical determination of identities on a purely relational (...) basis nor a determination specifically of identities in the sense of essences. Asymmetry is thus not by itself sufficient for a solution to CRO. But it cannot even help to answer CRO when a model for the determination of essences is taken as a basis. Nor is asymmetry necessary for a reply, as property structures may well be symmetric. A metaphysics of dispositional properties as grounded in a purely relational structure faces serious obstacles, and the properties would not be fundamental. Since essence and grounding are notions of metaphysical priority, there can be no essentially dispositional metaphysically fundamental properties, and the prospects of a “coherentist” metaphysics of basic properties are dim. A modal retreat that refrains from a post-modal conception of essence and simply claims that fundamental properties play dispositional roles by metaphysical necessity is unsatisfactory. (shrink)

The notions of ground and ontological dependence have made a prominent resurgence in much of contemporary metaphysics. However, objections have been raised. On the one hand, objections have been raised to the need for distinctively metaphysical notions of ground and ontological dependence. On the other, objections have been raised to the usefulness of adding ground and ontological dependence to the existing store of other metaphysical notions. Even the logical properties of ground and ontological dependence are under debate. In this article, (...) I focus on how to account for the judgements of non-symmetry in several of the cases that motivate the introduction of notions like ground and ontological dependence. By focusing on the notion of explanation relative to a theory, I conclude that we do not need to postulate a distinctively asymmetric metaphysical notion in order to account for these judgements.

Process theories of causality seek to explicate causality as a property of individual causal processes. This paper examines the capacity of such theories to account for the asymmetry of causation. Three types of theories of asymmetry are discussed; the subjective, the temporal, and the physical, the third of these being the preferred approach. Asymmetric features of the world, namely the entropic and Kaon arrows, are considered as possible sources of causal asymmetry and a physical theory of (...) class='Hi'>asymmetry is subsequently developed with special reference to the questions of objectivity and backwards causation.

We seem less likely to endorse moral expertise than reasoning expertise or aesthetic expertise. This seems puzzling given that moral norms are intuitively taken to be at least more objective than aesthetic norms. One possible diagnosis of the asymmetry is that moral judgments require autonomy of judgement in away that other judgments do not. However, the author points out that aesthetic judgments that have been ‘borrowed’ by aesthetic experts generate the same autonomy worry as moral judgments which are borrowed (...) by moral experts. The author then explores various approaches to accepting the testimony of moral experts and concludes that the asymmetry may best be explained by (1) the conditions for moral expertise being more difficult to satisfy than those of aesthetic expertise and (2) the intuitive greater seriousness of accepting the moral judgments of others, since moral norms are generally viewed as more binding than aesthetic norms.

In a previous paper, we argued that death's badness consists in the deprivation of pleasurable experiences which one would have had, had one died later rather than at the time of one's actual death. Thus, we argued that death can be a bad thing for the individual who dies, even if it is an experiential blank. But there is a pressing objection to this view, for if the view is correct, then it seems that it should also be the (...) case that it is a bad thing for a person that he is born when he actually is born, rather than earlier. That is, if the deprivation account is the correct account of death's badness, then it appears that one should have symmetric attitudes to prenatal and posthumous nonexistence. But clearly we do not in general have symmetric attitudes toward the period before our birth and the period after our death; in general, we do not think of our late births as a bad thing, but we can indeed consider our early deaths as bad for us. Thus, it appears that there is a problem for the deprivation account of death's badness. (shrink)

Lucretius thought that we should be as indifferent to the time of our death as we are toward the time of our birth. This paper will critique the ways in which Thomas Nagel, Frederik Kaufman and Christopher Belshaw have appealed to a psychological notion of the self in an attempt to defend our asymmetric intuitions against Lucretius’ claim. Four objections are marshalled against the psychological–self strategy: (1) the psychological notion of the self fails to capture all of our intuitions about (...) selfhood; (2) some of the intuitions to which proponents of a psychological notion of the self appeal are drawn from irrelevant or misleading ethical and epistemological aspects of certain examples they consider; (3) the arguments developed on the basis of a psychological notion of the self do not answer Lucretius in the right way; and (4) the psychological–self explanation overlooks an important distinction between awareness–dependent and awareness–independent explanations. While the psychological–self explanation of the asymmetry in our attitudes toward the time of our birth and the time of our death may explain why Nagel, Kaufman and Belshaw have asymmetric attitudes, it fails to explain why most people have such attitudes.

Recent research has demonstrated an asymmetry between the origins and endpoints of motion events, with preferential attention given to endpoints rather than beginnings of motion in both language and memory. Two experiments explore this asymmetry further and test its implications for language production and comprehension. Experiment 1 shows that both adults and 4-year-old children detect fewer within-category changes in source than goal objects when tested for memory of motion events; furthermore, these groups produce fewer references to source than (...) goal objects when describing the same motion events. Experiment 2 asks whether the specificity of encoding source/goal relations differs in both spatial memory and the comprehension of novel spatial vocabulary. Results show that endpoint configuration changes are detected more accurately than source configuration changes by both adults and young children. Furthermore, when interpreting novel motion verbs, both age groups expect more fine-grained lexical distinctions in the domain of endpoint configurations compared to that of source configurations. These studies demonstrate that a cognitive-attentional bias in spatial representation and memory affects both the detail of linguistic encoding during the use of spatial language and the specificity of hypotheses about spatial referents that learners build during the acquisition of the spatial lexicon.

In The Elm and The Expert (Fodor 1994), Jerry Fodor claims that in order to solve the mind/body problem (consciousness excluded), a computational psychology needs to be combined with a naturalistic theory of content such as the asymmetric dependence theory put forward in ‘A Theory of Content II’ (in Fodor 1990, pp. 89‐136). However, since this theory was first proposed, it has been reproached for a number of failings, perhaps the most significant of which is the objection that it (...) simply begs the question. In this paper I provide an outline of the story so far, covering Fodor's objectives, the theory he proposes to meet them and the objection in question, before going on to argue that a promising attempt to answer this objection will not bear fruit given the way in which Fodor tackles the original problems. I then argue that the seeming intractability of this objection is due to Fodor's striving to solve all the problems that a naturalistic theory presents in one fell swoop, and conclude by suggesting how, given a careful choice of targets and a well organised methodology, asymmetric dependence might yet prove to be an attractive theory of content.

An influential thought-experiment by Derek Parfit sought to establish that people have a preference for unpleasant events to lie in the past rather than the future. In recent discussions of Parfit’s argument, this purported preference is modelled as a discounting phenomenon, as is the tensed emotion of relief, which Arthur Prior argued demonstrated that there is an objective metaphysical difference between the past and the future. Looking at recent work demonstrating some psychological past/future asymmetries that are more clearly instances of (...) discounting I argue that this existing philosophical literature fails to distinguish between what are clearly two quite different psychological phenomena. This affects recent attempts to respond to Prior’s metaphysical argument, because it is not clear that they have identified the right phenomenon to be explained. It also affects Parfit’s thought-experiment, because the purported unitary ‘preference’ may in fact be an amalgam of these two quite different psychological phenomena. (shrink)

In defense of the Deprivation Approach to the badness of death against the Lucretian objection that death is relevantly similar to prenatal nonexistence, John Martin Fischer and Anthony L. Brueckner have suggested that whereas death deprives us of things that it is rational for us to care about, prenatal nonexistence does not. I have argued that this suggestion, even if correct, does not make for a successful defense of the Deprivation Approach against the Lucretian objection. My criticism involved (...) a thought experiment in which a person avoids being tortured. Recently, Taylor Cyr has defended Fischer and Brueckner’s approach, arguing that my thought experiment is incoherent. In this response, I question both the truth and relevance of Cyr’s incoherence claim. (shrink)

Future-bias is the preference, all else being equal, for positive states of affairs to be located in the future not the past, and for negative states of affairs to be located in the past not the future. Three explanations for future-bias have been posited: the temporal metaphysics explanation, the practical irrelevance explanation, and the three mechanisms explanation. Understanding what explains future-bias is important not only for better understanding the phenomenon itself, but also because many philosophers think that which explanation is (...) the correct one has implications for our evaluation of the normative status of future-bias. In this paper we focus on the connection between future-bias and the temporal value asymmetry. The latter refers to the fact that people tend to assign more value to a state of affairs when it is located in the future, as opposed to being equidistant in the past. All three candidate explanations offered for future-bias proceed by explaining the temporal value asymmetry, and then supposing that future-bias is simply a manifestation of that asymmetry. Recently, however, it has been argued that the conditions under which people display the temporal value asymmetry and future-bias are different, and that this is reason to doubt that the latter is a manifestation of the former. In this paper we empirically test one response to this argument against the manifestation thesis—the simulation response—according to which once we control for the degree to which people can simulate the object of their preference, we find that people display future-bias and the temporal value asymmetry in the same conditions. We find no evidence in favour of the simulation response. Moreover, our results support some previous research that suggests that the temporal value asymmetry is less robust than previously thought, and this in itself casts doubt on the idea that future bias is just a manifestation of this asymmetry.

This paper asks why causal asymmetries should give rise to explanatory asymmetries. One way to give some rationale for the asymmetries of causal explanation is to adopt a pragmatic view of explanation and to stress the fact that causes can be used to manipulate their effects. This paper argues, however, that when one recognizes that causal asymmetry is fundamentally an asymmetry of "connectedness", one can see how causal asymmetry leads to an objective difference between explanations in terms (...) of causes and explanations in terms of effects. The pragmatic differences are subsidiary. (shrink)

I assess the thesis that counterfactual asymmetries are explained by an asymmetry of the global entropy at the temporal boundaries of the universe by developing a new semantic element for counterfactuals called objective assertibility and a method of evaluating counterfactuals that constrains consideration to possibilities where the early universe has low entropy. The resulting theory vindicates the common practice of holding the past mostly fixed under counterfactual supposition while at the same time allowing the counterfactual's antecedent to obtain by (...) a natural physical development. While excellent for evaluating a wide variety of ordinary counterfactuals, it does not fully succeed as an explanation of counterfactual asymmetry. (shrink)

In multiple parts of the Critique of Pure Reason, Kant describes how time is dependent on space – which is the fundament of his distinction between inner and outer sense. However, he does not provide us with an argument for this dependency. In this article, two reasons for this dependency thesis are introduced. The first one aims at providing a conceptual link between time and space but runs into conflict with the Transcendental Aesthetic. The second one shifts our focus from (...) the conceptual level to a priori possible objects of experience: Time cannot provide such objects, which are different from our subjective states due to its one-dimensionality. Only space makes such objects possible. (shrink)

Is there a prima facie obligation to produce additional individuals whose lives would be worth living? In his paper ‘Is it Good to Make Happy People?’, Stuart Rachels argues not only that there is, but, also, that precisely as much weight should be assigned to the quality of life that would be enjoyed by such potential persons, if they were to be actualized, as to the quality of life enjoyed by actually existing persons. In response, I shall argue, first, that (...) Rachels’ view is exposed to very serious objections, and secondly, that his arguments in support of his position involve a crucial assumption, which cannot be sustained, concerning the relation between, on the one hand, propositions about good‐making and bad‐making properties, and, on the other, propositions about right‐making and wrong‐making ones. I shall then argue that there is a very plausible position concerning the conditions under which an action can be morally wrong which entails the following asymmetry: there is a prima facie obligation not to bring into existence individuals whose lives are not worth living, but there is no corresponding obligation to create additional individuals whose lives would be worth living.

This paper addresses the conflicting environmental interests of a firm and the community, an important stakeholder. The short-term profit maximization objective of a firm may stand in contrast with what the community wants – a "safe and clean environment". This paper argues that the information regarding the environmental impact of a firm's products, processes, and waste may be asymmetrically distributed between the firm and the community. The resultant information asymmetry may influence the probability of a firm acting opportunistically, and (...) ultimately, a firm's ethical behavior. The paper identifies information asymmetry between a firm and community, as well as that within the community. The perceived information asymmetry across various community segments may perhaps be a determinant of environmental discrimination. The paper further contends that information asymmetry may diminish in the long run. Finally it examines the implications of information asymmetry for firms and government policy. (shrink)

In this paper I explore the relationship between the “Humean” regularity view of causation, the view that a cause is a necessary condition of its effect, and the asymmetry of causation—the principle that if an event e1 causes e2, then it is false that e2 causes e1. I argue that the regularity view, in combination with the view that a cause is a necessary condition of its effect, is inconsistent with the asymmetry of causation, and that the inconsistency (...) can be removed by a modification of the view that a cause is a necessary condition of its effect that captures what is plausible in that view. I defend Hume, then, against the objection that he cannot accommodate a cause as being a necessary condition of its effect without absurdly denying the asymmetry of causation. This is only a limited defense, though, for I do not address the issue on which the tenability of the regularity view ultimately depends: viz., whether it can distinguish between causal laws and accidental generalizations without appealing to natural necessity.

The paper reviews Balashov’s Asymmetry Thesis concerning co-existing (point-sized) enduring objects, on the one hand, and perduring ones, on the other. In this regard, it becomes crucial to investigate whether, at a given spacetime point p, it is located only the respective temporal part of a perdur- ing whole, or that whole as well. Two alternatives ought to be distinguished and, then, I will argue as follows: If the perduring whole is located where its parts are, the original (...) class='Hi'>asymmetry- thesis has to be rejected. If, however, the perduring whole is not located where its parts are, the spatiotemporal locations of the parts can no longer be used to ground the co-existence relation. But, with the modified co-existence relation the asymmetry between perdurantism and endurantism turns out to be even much stronger than it has been assumed. (shrink)

The standard versions of predicativism are committed to the following two theses: proper names are count nouns in all their occurrences, and names do not refer to objects but express name-bearing properties. The main motivation for predicativism is to provide a uniform explanation of referential names and predicative names. According to predicativism, predicative names are fundamental and referential names are explained by appealing to a null determiner functioning like “the” or “that.” This paper has two goals. The first is to (...) reject the predicativists’ explanation of the two types of names. I present three syntactic counterexamples to the predicativists’ account of referential names: incorporation, modification, and measure phrase uses. The second goal is to present a novel strategy to explain the two types of names. I propose that referential names are fundamental but that there are null morphemes available for transforming a name into a count noun (and possibly into other syntactic categories). (shrink)

Recording of neural activity during grasping actions in macaques showed that grasp-related sensorimotor transformations are accomplished in a circuit constituted by the anterior part of the intraparietal sulcus (AIP), the ventral (F5) and the dorsal (F2) region of the premotor area. In humans, neuroimaging studies have revealed the existence of a similar circuit, involving the putative homolog of macaque areas AIP, F5, and F2. These studies have mainly considered grasping movements performed with the right dominant hand and only a few (...) studies have measured brain activity associated with a movement performed with the left non-dominant hand. As a consequence of this gap, how the brain controls for grasping movement performed with the dominant and the non-dominant hand still represents an open question. A functional magnetic resonance imaging (fMRI) experiment has been conducted, and effective connectivity (dynamic causal modeling, DCM) was used to assess how connectivity among grasping-related areas is modulated by hand (i.e., left and right) during the execution of grasping movements toward a small object requiring precision grasping. Results underlined boosted inter-hemispheric couplings between dorsal premotor cortices during the execution of movements performed with the left rather than the right dominant hand. More specifically, they suggest that the dorsal premotor cortices may play a fundamental role in monitoring the configuration of fingers when grasping movements are performed by either the right and the left hand. This role becomes particularly evident when the hand less-skilled (i.e., the left hand) to perform such action is utilized. The results are discussed in light of recent theories put forward to explain how parieto-frontal connectivity is modulated by the execution of prehensile movements. (shrink)

Some things look more complex than others. For example, a crenulate and richly organized leaf may seem more complex than a plain stone. What is the nature of this experience—and why do we have it in the first place? Here, we explore how object complexity serves as an efficiently extracted visual signal that the object merits further exploration. We algorithmically generated a library of geometric shapes and determined their complexity by computing the cumulative surprisal of their internal skeletons—essentially quantifying the (...) “amount of information” within each shape—and then used this approach to ask new questions about the perception of complexity. Experiments 1–3 asked what kind of mental process extracts visual complexity: a slow, deliberate, reflective process (as when we decide that an object is expensive or popular) or a fast, effortless, and automatic process (as when we see that an object is big or blue)? We placed simple and complex objects in visual search arrays and discovered that complex objects were easier to find among simple distractors than simple objects are among complex distractors—a classic search asymmetry indicating that complexity is prioritized in visual processing. Next, we explored the function of complexity: Why do we represent object complexity in the first place? Experiments 4–5 asked subjects to study serially presented objects in a self‐paced manner (for a later memory test); subjects dwelled longer on complex objects than simple objects—even when object shape was completely task‐irrelevant—suggesting a connection between visual complexity and exploratory engagement. Finally, Experiment 6 connected these implicit measures of complexity to explicit judgments. Collectively, these findings suggest that visual complexity is extracted efficiently and automatically, and even arouses a kind of “perceptual curiosity” about objects that encourages subsequent attentional engagement.

BackgroundIn Parkinson's disease, the side of motor symptoms onset may influence disease progression, with a faster motor symptom progression in patients with left side lateralization. Moreover, worse neuropsychological outcomes after subthalamic nucleus deep brain stimulation have been described in patients with predominantly left-sided motor symptoms. The objective of this study was to evaluate if the body side of motor symptoms onset may predict motor outcome of bilateral STN-DBS.MethodsThis retrospective study included all consecutive PD patients treated with bilateral STN-DBS at Grenoble (...) University Hospital from 1993 to 2015. Demographic, clinical and neuroimaging data were collected before and 1 year after surgery. The predictive factors of motor outcome at one-year follow-up, measured by the percentage change in the MDS-UPDRS-III score, were evaluated through univariate and multivariate linear regression analysis.ResultsA total of 233 patients were included with one-year follow-up after surgery [143 males ; 121 right body onset; 112 left body onset; mean age at surgery, 55.31 ± 8.44 years; mean disease duration, 11.61 ± 3.87]. Multivariate linear regression analysis showed that the left side of motor symptoms onset did not predict motor outcome.ConclusionsIn this retrospective study, the body side of motor symptoms onset did not significantly influence the one-year motor outcome in a large cohort of PD patients treated with bilateral STN-DBS.

According to the New Angle, any explanation of the Knobe effect must be gradable and asymmetric. It has been argued that only Hindriks’ approach meets both criteria. First, we argue that Holton’s hypothesis also meets the criteria. Second, we show that the authors are not justified in taking the criteria to be empirically justified. We have failed to replicate the asymmetry result in two experiments. Moreover, gradability can be objective or epistemic. We show that the New Angle presupposes objective (...) gradability. In our experiments, the patterns of responses to questions about epistemic and objective gradability are the same, irrespective of whether the feature is objectively gradable (e.g., blameworthiness) or not (e.g., intentionality). Our results thus question the extent to which the New Angle is empirically grounded. Moreover, they raise doubt whether the answers to questions about epistemic and objective gradability can be taken at face value at all. (shrink)

In this paper, I propose a solution to a challenge formulated by Judith Jarvis Thomson: We have to explain why the moral asymmetry between doing and allowing harm is a deep feature of our moral thinking. In a nutshell, my solution is this: It could not be otherwise. Accepting the asymmetry is indispensable for the construction and maintenance of stable moral communities. -/- My argument centrally involves mental resource management. Moral communities depend on their members’ commitment to moral (...) norms. And, I argue, community members can only be committed to these norms in the required ways without overextending their mental resources if morality contains the doing/allowing asymmetry. -/- This has two noteworthy implications. Firstly, we can and should stop discussing the asymmetry in normative ethics and, instead, regard it as “moral axiom” we cannot but accept. Secondly, even consequentialists have to accept the asymmetry but, by doing so, their view loses part of its intuitive appeal. Lastly, I turn to an objection. One might think that my indispensability argument confuses issues in moral psychology with issues in normative ethics. I reject the objection on broadly pragmatist grounds. (shrink)

This paper presents a new challenge to the thesis that moral responsibility for an omission requires the ability to do the omitted action, whereas moral responsibility for an action does not require the ability to do otherwise than that action. Call this the asymmetry thesis. The challenge arises from the possibility of cases in which an omission is identical to an action. In certain of such cases, the asymmetry thesis leads to a contradiction. The challenge is then extended (...) to recent variations of the asymmetry thesis defended by John Martin Fischer and Carolina Sartorio. Finally, a possible objection to the challenge is addressed.

there seems to be some kind of asymmetry, at least in some cases, between moral testimony and non-moral testimony, between aesthetic testimony and non-aesthetic testimony, and between religious testimony and non-religious testimony. In these domains, at least in some cases, we object to deference, and for this reason expect people to form their beliefs on non-testimonial grounds, in a way that we do not object to deference in paradigm cases of testimonial knowledge. Our philosophical puzzle is therefore: what explains (...) these (apparent) asymmetries (or are they merely apparent)? My aim here is to criticize three accounts of these testimonial asymmetries and to suggest an alternative strategy for solving our puzzle. I’ll consider the idea that testimony cannot be a source of understanding (§2), the idea that testimony cannot be a source of acquaintance (§3), and the idea that testimonial belief is not conducive to moral virtue (§4). These accounts all explain the badness of testimonial belief, in the relevant cases, by appeal to its consequences for the believer—respectively, a lack of understanding, acquaintance, or moral virtue. I’ll conclude by suggesting a way forward (§5): we should try to understand the badness of testimonial belief, in the relevant cases, as deriving from its consequences for the believer’s society.

In this paper, I present a non standard objection to moral impartialism. My idea is that moral impartialism is questionable when it is committed to a principle we have reasons to reject: the principle of self-other symmetry. According to the utilitarian version of the principle, the benefits and harms to the agent are exactly as relevant to the global evaluation of the goodness of his action as the benefits and harms to any other agent. But this view sits badly (...) with the “Harm principle” which stresses the difference between harm to others and harm to the self. According to the deontological version, we have moral duties to ourselves which are exactly symmetrical to our duties to others. But there are reasons to believe that the idea of a duty to the self is not coherent. (shrink)

This paper explores an empirical puzzle, namely, how inter-organizational relationships can be sustained between organizations that draw upon distinctive—and potentially conflicting—institutional logics under conditions of power asymmetry. This research analyses cases of these relationships and suggests some key conditions underlying them. Examining relationships between ‘Fair Trade’ organizations and corporate retailers, a series of contingent factors behind the dynamic persistence of such relationships are proposed, namely: the presence of pre-existing ‘hybrid logics’; the use of boundary-spanning discourses; joint tolerance of conflict; (...) and co-creation of common rules. These four elements are supported by a fifth mediating factor, i.e. the presence and use of a Fair Trade certification system in the collaboration. The latter appears as a central vehicle facilitating cross-logic relationships—it can be seen as a ‘boundary object’ embodying a series of narratives and discourses that are open to multiple interpretations corresponding to the dominant institutional logics of each partner organization.

Ascriptions of truth give rise to an explanatory asymmetry. For instance, we accept ‘ is true because Rex is barking’ but reject ‘Rex is barking because is true’. Benjamin Schnieder and other philosophers have recently proposed a fresh explanation of this asymmetry : they have suggested that the asymmetry has a conceptual rather than a metaphysical source. The main business of this paper is to assess this proposal, both on its own terms and as an option for (...) deflationists. I offer a pair of objections to the proposal and defend them from counter-objections. To conclude, I discuss how else to explain the asymmetry, and set out the implications for deflationism and correspondence theories of truth. (shrink)

How does causation in the physical world relate to implication in logic? This article presents implication as fundamentally a relation of inclusion between propositions. Given this, it is argued that an event cannot “causally imply” another, also given the laws of nature. Then, by applying the notion of inclusion to physical objects, a relation “within the possibilities of” is developed, which generates a partial order on sets of entities and is independent of time. Based on this, it is shown that (...) changes of physical objects in time (at any rate, a great many of them) imply, and thus counterfactually depend on, what we call “causes” – an asymmetric dependence which is robust despite the perspectival nature of the concept of “cause”.

In some jurisdictions there is a puzzling asymmetry between consent and refusal, where, for some kinds of treatment, the adolescent patient has the power to permit her own treatment but her refusal does not have the same kind of normative significance as refusal of treatment by a competent adult. In this journal I recently offered a clarification and defence of this asymmetry in terms of a paternalistic justification of the sharing of normative powers between adolescents and other parties. (...) Lawlor offers a number of objections to this account. Three of his objections can be dealt with quickly. But one of them is much more challenging: the asymmetry of consent and refusal entails a practice of making sham offers. They do not really offer a choice at all. Genuine offers seem to require a commitment to be symmetrically responsive to whatever decision outcome is reached by the recipient of the offer. When we reflect upon the way that offers can be made in complex social contexts, where different parties have a ‘say’ in what ought to be done, the symmetry of responsiveness need not apply. Offers can be genuine, without being symmetrically responsive. Contrary to the seemingly plausible objection, the asymmetry of consent and refusal does not entail sham offers, or the offer of ‘sham choices’. (shrink)

This paper argues that, assuming some widely held views about how vision justifies beliefs, there is an important epistemic asymmetry between visual perception and the perception of bodily sensations. This asymmetry arises when we consider the epistemic significance of the distinction between low-level and high-level properties in perceptual experience. I argue that a distinction exists between low-level and high-level properties of bodily sensations which parallels that distinction in the objects of visual experience. I then survey evidence revealing systematic (...) unreliability in an important dimension of our perception of low-level bodily sensational properties. I argue that this unreliability results in an epistemic asymmetry with vision. I conclude by sketching some implications of this asymmetry for developing a general, unified theory of perceptual justification. (shrink)
