Previous studies have shown that children retreat from argument‐structure overgeneralization errors (e.g., *Don’t giggle me) by inferring that frequently encountered verbs are unlikely to be grammatical in unattested constructions, and by making use of syntax‐semantics correspondences (e.g., verbs denoting internally caused actions such as giggling cannot normally be used causatively). The present study tested a new account based on a unitary learning mechanism that combines both of these processes. Seventy‐two participants (ages 5–6, 9–10, and adults) rated overgeneralization errors with higher (...) (*The funny man’s joke giggled Bart) and lower (*The funny man giggled Bart) degrees of direct external causation. The errors with more‐direct causation were rated as less unacceptable than those with less‐direct causation. This finding is consistent with the new account, under which children acquire—in an incremental and probabilistic fashion—the meaning of particular constructions (e.g., transitive causative = direct external causation) and particular verbs, rejecting generalizations where the incompatibility between the two is too great.

In the biomedical context, policy makers face a large amount of potentially discordant evidence from different sources. This prompts the question of how this evidence should be aggregated in the interests of best-informed policy recommendations. The starting point of our discussion is Hunter and Williams’ recent work on an automated aggregation method for medical evidence. Our negative claim is that it is far from clear what the relevant criteria for evaluating an evidence aggregator of this (...) sort are. What is the appropriate balance between explicitly coded algorithms and implicit reasoning involved, for instance, in the packaging of input evidence? In short: What is the optimal degree of ‘automation’? On the positive side: We propose the ability to perform an adequate robustness analysis as the focal criterion, primarily because it directs efforts to what is most important, namely, the structure of the algorithm and the appropriate extent of automation. Moreover, where there are resource constraints on the aggregation process, one must also consider what balance between volume of evidence and accuracy in the treatment of individual evidence best facilitates inference. There is no prerogative to aggregate the total evidence available if this would in fact reduce overall accuracy. (shrink)

To solve the referential sub-problem of negative existentials one must explain why we interpret uses of, e.g., ‘Sherlock Holmes doesn’t exist’ as saying something coherent and intuitively true, even though the speaker purports to refer to something. Pragmatic Meinongism solves this problem by allowing ‘does not exist’ to be pragmatically modulated to express an inclusive sense under which it can be satisfied by something. I establish three points in defense of pragmatic Meinongism: it is superior to Russell-inspired (...) solutions; it is supported by independent evidence of pragmatic modulation; and it requires no dubious ontological commitments.

Children learn their native language by exposure to their linguistic and communicative environment, but apparently without requiring that their mistakes be corrected. Such learning from “positive evidence” has been viewed as raising “logical” problems for language acquisition. In particular, without correction, how is the child to recover from conjecturing an over-general grammar, which will be consistent with any sentence that the child hears? There have been many proposals concerning how this “logical problem” can be dissolved. In this study, (...) we review recent formal results showing that the learner has sufficient data to learn successfully from positive evidence, if it favors the simplest encoding of the linguistic input. Results include the learnability of linguistic prediction, grammaticality judgments, language production, and form-meaning mappings. The simplicity approach can also be “scaled down” to analyze the learnability of specific linguistic constructions, and it is amenable to empirical testing as a framework for describing human language acquisition.

Natural language is full of patterns that appear to fit with general linguistic rules but are ungrammatical. There has been much debate over how children acquire these “linguistic restrictions,” and whether innate language knowledge is needed. Recently, it has been shown that restrictions in language can be learned asymptotically via probabilistic inference using the minimum description length (MDL) principle. Here, we extend the MDL approach to give a simple and practical methodology for estimating how much linguistic data are required to (...) learn a particular linguistic restriction. Our method provides a new research tool, allowing arguments about natural language learnability to be made explicit and quantified for the first time. We apply this method to a range of classic puzzles in language acquisition. We find some linguistic rules appear easily statistically learnable from language experience only, whereas others appear to require additional learning mechanisms (e.g., additional cues or innate constraints).

The question of whether or not to partition data for the purposes of inferring phylogenetic hypotheses remains controversial. Opinions have been especially divided since Kluge's (1989, Systematic Zoology 38, 7–25) claim that data partitioning violates the requirement of total evidence (RTE). Unfortunately, advocacy for or against the RTE has not been based on accurate portrayals of the requirement. The RTE is a basic maxim for non-deductive inference, stipulating that evidence must be considered if it has relevance to an (...) inference. Evidence is relevant if it has a positive or negative effect on a given conclusion. In the case of ℈partitioned’ phylogenetic inferences, the RTE is violated, and the basis for rational belief in any conclusion is compromised, unless it is shown that the partitions are evidentially irrelevant to one another. The goal of phylogenetic systematics is to hypothesize past causal conditions to account for observed shared similarities among two or more species. Such inferences are non-deductive, necessitating consideration of the RTE. Some phylogeneticists claim the parsimony criterion as justification for the RTE. There is no relation between the two – parsimony is a relation between a hypothesis and causal question(s). Parsimony does not dictate the content of premises prior to an inference. ℈Taxonomic congruence,’ ℈supertrees,’ and ℈conditional combination’ methods violate the RTE. Taxonomic congruence and supertree methods also fail to achieve the intended goal of phylogenetic inference, such that ℈consensus trees’ and ℈supertrees’ lack an empirical basis. ℈Conditional combination’ is problematic because hypotheses derived from partitioned data cannot be compared – a causal hypothesis inferred to account for a set of effects only has relevance to those effects, not any comparative relevance to other causal hypotheses. A similar problem arises in the comparisons of hypotheses derived from different causal theories. (shrink)

Norris et al.'s claim that feedback is unnecessary is compromised by (1) a questionable application of Occam's razor, given strong evidence for feedback in perception; (2) an idealization of the speech recognition problem that simplifies those aspects of the input that create conditions where feedback is useful; (3) Norris et al.'s use of decision nodes that incorporate feedback to model some important empirical results; and (4) problematic linking hypotheses between crucial simulations and behavioral data.

Voluntarism about beliefs is the view that persons can be free to choose their beliefs for non-epistemic (truth-related) reasons (cf. Williams 1973). One problem for belief voluntarism is that it can lead to Moore-paradoxality. The person might believe that -/- a.) there are also good epistemic reasons for her belief, or that b.) there are no epistemic reasons one way or the other, or that c.) there are good epistemic reasons against her belief. -/- If the person is aware (...) of the fact that she chose her belief for non-epistemic reasons, then she would believe one of the following three things (using "evidence" as a term for all kinds of epistemic reasons): -/- a.) I believe that p but not because of the good evidence in favour of it; b.) I believe that p but that has nothing to do with the evidence; c.) I believe that p but the evidence speaks against it. -/- We could add a fourth case in which the person suspends belief on the subject matter despite the evidence: -/- d.) The evidence supports "p" but I have no view on the matter. -/- All the different versions a-d are somehow Moore-paradoxical. They constitute different ways of mistrusting one's own belief (cf. Wittgenstein 1958, p.190). Given that one cannot, for conceptual reasons, mistrust one's beliefs, it follows that a person cannot be in one of the above predicaments described by a-d. Hence, voluntarism about beliefs is false, at least if we are dealing with cases in which the person is aware of the fact that she chose her belief for non-epistemic reasons. It won't help to focus on cases in which the person is not aware of that fact, either because she has forgotten the genesis of her belief or because the process of belief acquisition was unconscious. -/- Bas van Fraassen's conception of a stance (cf. van Fraassen 2002)-a mix of commitments, values, goals-gives us reason to rethink the possibility of voluntarism. Might we be free to choose our stances for non-epistemic reasons? I argue here that the answer is negative. First, it is not clear at all whether stances can be objects of choice, properly speaking. And: Can we make sense of the idea of a free choice here? Furthermore, I argue that similar problems of Moore-paradoxality would arise for voluntarism about stances. If one does not want to completely devalue the idea of a stance, one should avoid voluntarism. (shrink)

God and Evidence presents a new set of compelling problems for theistic philosophers. The problems pertain to three types of theistic philosopher, which Lovering defines here as 'theistic inferentialists,' 'theistic non-inferentialists,' and 'theistic fideists.' Theistic inferentialists believe that God exists, that there is inferential probabilifying evidence of God's existence, and that this evidence is discoverable not simply in principle but in practice. Theistic non-inferentialists believe that God exists, that there is non-inferential probabilifying evidence of God's existence, (...) and that this evidence is discoverable not simply in principle but in practice. Theistic fideists believe that God exists, that there is no discoverable probabilifying evidence (inferential or non-inferential) of God's existence, and that it is nevertheless acceptable-morally if not otherwise-to have faith that God exists. Lovering argues that each type of theistic philosopher faces a problem unique to his type and that they all share two particular problems. Some of these problems take us down an entirely new discursive path; others down a new discursive path branching off from an old one. (shrink)

IN THE beginning Parmenides sought to deny the void. But he found himself trapped by his language and his thought into admitting what he sought to deny. Wisely, he counseled others to avoid the whole region in which the problem arises, lest they too be unwarily ensnared. Plato, being less easily intimidated and grasping for the first time the urgency of the paradox, unearthed each snare in turn until he felt he had found a safe path through the forbidden (...) terrain in a new conception of being and the derivation of its linguistic consequences in the Sophist. Aristotle evidently took Parmenides’ advice; and save for a few groping scholastics, perhaps Leibniz, Brentano, and Meinong, and Frege only in passing, no one else attempted the crossing before Russell made his spectacular dash through the posted ground from the completely new direction of linguistic reference. Again the problem lay dormant for half a century until Strawson constructed a new low road through ordinary language and Quine improved Russell’s high algebraic pass. Refinements of these routes have been forthcoming, especially from Searle and Kripke, until today it might appear that there are two super highways through Parmenides’ forbidden country of nonbeing. In this essay I will first argue that these new linguistic highways are no more than flimsy camouflage hiding but not resolving the old paradoxes. I will then show how Plato’s ontological way out, though more difficult, is the straight and narrow path. (shrink)

Whilst certain verbs may appear in both the intransitive inchoative and the transitive causative constructions (The ball rolled/The man rolled the ball), others may appear in only the former (The man laughed/*The joke laughed the man). Some accounts argue that children acquire these restrictions using only (or mainly) statistical learning mechanisms such as entrenchment and pre-emption. Others have argued that verb semantics are also important. To test these competing accounts, adults (Experiment 1) and children aged 5–6 and 9–10 (Experiment 2) (...) were taught novel verbs designed to be construed — on the basis of their semantics — as either intransitive-only or alternating. In support of the latter claim, participants' grammaticality judgments revealed that even the youngest group respected these semantic constraints. Frequency (entrenchment) effects were observed for familiar, but not novel, verbs (Experiment 1). We interpret these findings in the light of a new theoretical account designed to yield effects of both verb semantics and entrenchment/pre-emption. (shrink)

We show that if R is a nonconstant regular (semi-)local subring of a rational function field over an algebraically closed field of characteristic zero, Hilbert's Tenth Problem for this ring R has a negative answer; that is, there is no algorithm to decide whether an arbitrary Diophantine equation over R has solutions over R or not. This result can be seen as evidence for the fact that the corresponding problem for the full rational field is also (...) unsolvable. (shrink)

The meta-problem is 'the problem of explaining why we think that there is a problem of consciousness' (Chalmers, 2018, p. 6). This presupposes that we think there is a problem in the first place. We challenge the breadth of this 'we', arguing that there is already sufficient empirical evidence to cast doubt on the claim. We then add to this body of evidence, presenting the results of a new cross-cultural study extending the work of (...) Sytsma and Machery (2010). (shrink)

Only recently research in social psychology has started to systematically investigate intergroup attitudes among members of stigmatized minority groups. In particular, the study of the way people with mental health problems perceive the social groups around them is so far very scarce. In this work, we focused on people with schizophrenia, analyzing their attitudes toward another stigmatized group, namely Black individuals. In Study 1, the attitudes toward White and Black people were assessed in a sample of respondents with a diagnosis (...) of schizophrenia and in a sample of non-clinical individuals. Results showed the presence of less negative attitudes toward the minority outgroup among the clinical sample. In Study 2, we aimed at investigating what members belonging to the majority group believe about the attitudes toward Black people held by individuals with a diagnosis of schizophrenia. In general, results suggested a general awareness in lay persons that people with a diagnosis of schizophrenia, as compared to people with no history of mental disorders, hold reduced negative attitudes toward Black individuals. Overall, these results may help to enrich our knowledge about social cognition among members of stigmatized groups in general and, more specifically, among individuals with a diagnosis of schizophrenia.

One common mistake in discussions about the ethics of infant male circumcisioni is to attempt to answer the question of the practice's permissibility by appealing to general principles and bypassing the empirical evidence about purported benefits and harms of the practice.Joseph Mazor1 avoids the mistake of appealing only to general principles. He correctly argues that it is not sufficient to invoke a child's right to bodily integrity or to self-determinationii. Moreover, he does not appeal to parents’ rights to religious (...) or cultural freedom in order to make his case for the permissibility of parents having their sons circumcised for religious or cultural reasons.However, in invoking empirical considerations, he is insufficiently careful. For example, he includes, on the negative side of the circumcision ledger, a reduction in sexual pleasure, yet it is not clear that even his own reasoning warrants this. The problem is that he seems to want both, to acknowledge the absence of clear evidence for this claim, and to accept it as one of the costs of circumcision.He says that Michael Benatar and I2 ‘carefully reviewed the medical evidence’1 about circumcision. In the paper that he cites, we noted that competing claims were made about the effect of circumcision on sexual pleasureiii and we established that no conclusion could be drawn from the limited and conflicting evidence available on this question. Dr Mazor notes that critics could point to those studies that lend support to the conclusion that circumcision reduces sexual pleasure, but he concedes that this would be controversial,1 …. (shrink)

Imagine slicing your hand with a steak knife. Inevitably, this leads to a characteristic unpleasant sensation, and just as reliably, to a withdrawal of the wounded limb. But can this rather mundane fact--and other similar facts--shed any light on the mind-body problem or the issue of the role of experience in causing behavior? In my dissertation, I explore this issue head on, and in the process clarify and criticize the arguments of philosophers who have given an affirmative answer to (...) this question--philosophers such as William James and Herbert Spencer. These arguments have coupled evidence like the above with the fact that human beings have evolved, in order to make the case that epiphenomenalism with respect to qualia is false. My first task will be to formulate a rigorous version of a James-Spencer style argument, which will occupy us in Chapter 1. Chapter 2 is dedicated to answering a number of objections to the argument, in an effort to show that if there is a problem with it, this problem lies elsewhere. Chapter 3 explores alternative arguments in the spirit of the original one formulated in Chapter 1, and discusses any resulting effects on the plausibility of the conclusion. Chapter 4 is the capstone chapter of the dissertation. In it, I discuss a crucial objection to all arguments in the spirit of that given in the first chapter--namely, that physicalism has analogous flaws to epiphenomenalism where accommodating the relevant evidence is concerned. My conclusions in this final chapter are twofold. First, that even if there is no fatal flaw in the general strategy the evolutionary argument employs, it works against all forms of dualism, not just epiphenomenalism. And second, the accusations made in the objection are correct; physicalism suffers from problems analogous to those faced by epiphenomenalism. Although the primary findings of the dissertation are negative, there are many lessons we can take from them along the way. Most prominent among them is an improved perspective on the appropriate roles of empirical findings and armchair philosophical theorizing in debate over the mind-body problem. (shrink)

It has recently been proposed that the evolution of human cooperativeness might, at least in part, have started as the cooptation of behavioral strategies evolved for solving problems of coordination to solve problems with higher incentives to defect, i.e. problems of cooperation. Following this line of thought, we systematically tested human subjects for spillover effects from simple coordination tasks (2x2 Stag Hunt games, SH) to problems of cooperation (2x2 Prisoner’s Dilemma games, PD) in a laboratory experiment with rigorous controls to (...) rule out subject confusion or habituation. Supporting the hypothesis that decision mechanisms for cooperation problems are linked with decision mechanisms for coordination, our main finding is that cooperation levels in PD games embedded in a sequence of SH games were significantly increased compared to a baseline sequence consisting only of PDs when subjects played in fixed pairs. No such effects could be found when players were randomly rematched each round. Additional findings include that this spillover effect cannot prevent a decay of cooperation over time, that there is no indication of a reversed effect, i.e. no signs of negative spillovers from failed cooperation to miscoordination, and that subjects self-reported preferences in SH games are prosocial.

The seeming absence of negative evidence in the input that children receive during language acquisition has long been regarded as a serious problem for non-nativist linguistic theories. Among the solutions that have been suggested for this problem, preemption by competing structures is doubtless the most intensively researched and widely accepted. However, while preemption works well in the domain of morphology, it cannot apply categorically in the domain of syntax, as this would preclude the existence of semantically (...) overlapping constructions, such as the ditransitive and the prepositional dative, which can be used alternatively with many, but not all, verbs of literal or metaphorical transfer. This paper investigates one specific version of preemption briefly entertained by Pinker (Language learnability and language development, Harvard University Pressm, 1984), which would account both for the existence of semantically overlapping constructions and for the fact that these constructions may preempt each other in the case of individual verbs. Typically, such pairs of grammatical constructions differ in their information-structural restrictions and speakers tend to choose the construction that best fits a given discourse context; when speakers use a construction even though there is an alternative that fits the discourse context better, children may take this as evidence that the alternative is not available for the specific verb in question. Two corpus studies are presented, comparing the information-structural profile of prepositional dative constructions containing verbs that may alternate between the dative and the ditransitive with the information structural profile of verbs that are restricted to the prepositional dative. For Pinker's preemptive mechanism to be feasible, there should be a clear and systematic difference in the information-structural profile of these two classes of verbs. However, no such difference can be found in actual usage. (shrink)

1. To list Pound’s triumphs of recognition in the realm of art, music, or literature is by itself no more enlightening than to catalog his oversights. Thus, for example, his instant and almost uncanny responsiveness to the work of Henri Gaudier-Brzeska is not more informative than his bizarre ranking of Francis Picabia’s paintings above those of Picasso or Matisse. Clearly it is essential to know, with as much specificity as possible, exactly what Pound said about a particular work of art (...) or literature and, equally important, given the frequent shifts of emphasis and interest throughout his long career, just when these opinions were first formulated. Like every reader of the The Cantos, I am conscious of the enormous service rendered by Pound scholars whose research is giving us a more complete inventory of the poet’s various statements and positions, and it would be foolish to take my point here as a derogation of such efforts. But a list, no matter how complete, is not an argument, and an inventory, no matter how scrupulously assembled, is not an explanation; a recurrent problem in Pound studies is that too often the compoilation of discrete items of information is seen as a sufficient answer to problems of interpretation and understanding. In other words, I think it essential that discussions of pound and the Visual Arts move beyond the quagmire resulting from still another frain-storm of “factual atoms” chronicling his various passions and dislikes.2. Far from implying, however, that we must therefore simply accept Pound’s brilliant discoveries and pass over his “howling blunders,” my position would emphasize the need to take his ideas seriously enough to confront them, to test them against the material to which they are a response and for which they often seek to provide an explanatory account. There are times, as I have argued in an analogous context, when it is less demeaning to give a man credit for his worst errors than to remove from him the capacity to err.3. What we require, I believe, is less a catalog of all of Pound’s specific statements about various artists, with each utterance assigned a positive or negative prefix depending upon our own personal and currently sanctioned hierarchy of values, than a careful study of the place of those statements in the logic and texture of Pound’s own work. The attempt to focus attention on The Cantos’ network of artistic references—its invocation of masterpieces and privileged moments of cultural achievement—will yield only trivial results unless the inner dynamic linking Pound’s various exampla and the actual role these play in the poem’s argument become clearer in the process. Michael André Bernstein, associate professor of English and comparative literature at the University of California, Berkeley, is the author of The Tale of the Tribe: Ezra Pound and the Modern Verse Epic and Prima della Rivoluzione , a volume of verse.

Recent years have seen a renewal of the perennial debate concerning innate ideas: Noam Chomsky has argued that much of our knowledge of natural languages is innate; Jerry Fodor has defended the innateness of most concepts. ;Part One concerns the historical controversy over nativism. On the interpretation there developed, nativists have defended two distinct theses. One, based on arguments from the poverty of the stimulus, is a psychological theory postulating special-purpose learning mechanisms. The other, deriving from arguments entailing that learning (...) from experience is impossible, is the meta-psychological view that we can hope for no real explanation of how learning occurs. ;In Part Two, the views of contemporary nativists are discussed against this background. Fodor's claim that our concepts are 'triggered' rather than 'learned' provides no account of concept-acquisition. Instead, it expresses his view that concept-acquisition resists any psychological explanation. But while 'brute-causal' interaction with the world may be necessary to the fixation of reference--and hence to the attainment of concepts--it is insufficient. Mind-world interaction is 'cognitively mediated' and it is in explaining the nature of this mediation that psychology will play a role. ;Chomsky holds that we have a special-purpose faculty for learning language. His 'a posteriori' arguments from the poverty of the stimulus, being based on unsubstantiated empirical claims about the pld and the course of learning, are rejected. Another 'a priori' argument exists, however, involving only the general observation that since the pld contain little information about what is not a sentence, a special mechanism is required to prevent overgeneration. But negative data are lacking in every learning domain. So since it is implausible that all learning requires special faculties, there must be a general-purpose strategy that can skirt the 'negative evidence' problem. Whether it is used for language-learning remains moot. But what really motivates the Chomskian is his awe at what children achieve, namely, 'cognizance' of a grammar. Grammars prove, however, to be 'psychologically real' in such a weak sense that the phenomena of language mastery provides little grist to the nativist's mill. (shrink)

Misconduct has permeated almost every community across the globe and Christian churches have not been spared either. The two basic questions that the current study addresses were what are some of the reported behaviours of male pastors that constitute misconduct in the Apostolic Faith Mission in Zimbabwe church?; and is there any policy framework in the AFM in Zimbabwe designed to repair distressed relationships between offending pastors and the church? Results showed that in the AFM in Zimbabwe, pastoral misconduct is (...) seen as a negative force that militates against sustaining harmony in the church. As such, whenever a male pastor commits an act of misconduct, disciplinary action is taken against him. It was also found that constructive dialogue to address misconduct is still a blind spot in the church under review. And because there is no policy framework to amend distressed relationships after administering discipline, social interactions between offending pastors and the church remain antagonistic. In view of the identified problem, this study proposed that the AFM in Zimbabwe might need to embrace a peace building framework because it has the propensity to repair broken relationships and to build friendships, social networks and trust between people. This framework can be instrumental in repairing distressed relations between offending pastors and the church at large. The strength of peace building lies in the values of brotherly love, forgiveness, reconciliation and relationship building, which are compatible with Christianity. (shrink)

The bulk of this book is the second series of John Dewey Lectures, delivered by Professor Ayer in April 1970. To this, Ayer has added a criticism of Roy Harred’s purported refutation of Hume and a chapter about "non-truth-functional" conditionals that rounds out the lectures. Leaving Harred aside, this book provides an elegant, concise, and up-to-date introduction to the problem of induction and related issues concerning probability. Hume is here vindicated. Beginning by giving what may be the best, updated (...) paraphrase of Hume’s negative argument about causal judgments, Ayer explicates the subsumed atomicity, the denial of natural necessity, and the claimed vacuity or circularity of introducing the "uniformity of nature." Ayer goes on to distinguish a priori or logical probabilities, statistical or frequency judgments, and credibility or ground floor inductive judgments, and he summarily argues that the admissibility of the first two forms of judgment, properly understood, provides no real justification for credibility judgments, which, though not defined as subjective, turn out to need some support from our decision to project and therefore entrench certain predicates, or take as lawlike certain generalizations, rather than others. Ayer here includes a very clear explication and criticism of Carnap’s way out in the Logical Concept of Probability, and elsewhere. Ayer acutely summarizes and discusses the Hempel and Goodman paradoxes, taking a position substantially in agreement with Quine and Goodman, and welds this discussion into a Humean conclusion: "In a certain sense cases are what we choose them to be. We do not decide what facts habitually go together but we do decide what combinations are to be imaginatively projected. The despised savages who beat gongs at solar eclipses to summon back the sun are not making any factual error. It is a true generalization that whenever they beat the gongs the sun does shine again, and if they always keep up the ceremony, it is also a true generalization that the sun comes out again only when they beat the gongs. If we despise them, it is because they tell a fictional story about what would happen if they did not beat the gongs, which we do not accept. They see what goes on as well as we do; it is just that we have a different and, we think, a better idea of the way the world works." To say all this is just, of course, to summarize and refurbish Hume’s position on causality. But to do that has two very real values now: 1) It underlines and exposes the epistemic basis of the position taken by Hume’s heirs; 2) It makes clear what are the departures required if one is to differ in substance from Hume and Ayer.—J.

For most of the history of prejudice research, negativity has been treated as its emotional and cognitive signature, a conception that continues to dominate work on the topic. By this definition, prejudice occurs when we dislike or derogate members of other groups. Recent research, however, has highlighted the need for a more nuanced and “inclusive” (Eagly 2004) perspective on the role of intergroup emotions and beliefs in sustaining discrimination. On the one hand, several independent lines of research have shown that (...) unequal intergroup relations are often marked by attitudinal complexity, with positive responses such as affection and admiration mingling with negative responses such as contempt and resentment. Simple antipathy is the exception rather than the rule. On the other hand, there is mounting evidence that nurturing bonds of affection between the advantaged and the disadvantaged sometimes entrenches rather than disrupts wider patterns of discrimination. Notably, prejudice reduction interventions may have ironic effects on the political attitudes of the historically disadvantaged, decreasing their perceptions of injustice and willingness to engage in collective action to transform social inequalities.These developments raise a number of important questions. Has the time come to challenge the assumption that negative evaluations are inevitably the cognitive and affective hallmarks of discrimination? Is the orthodox concept of prejudice in danger of side-tracking, if not obstructing, progress towards social justice in a fuller sense? What are the prospects for reconciling a prejudice reduction model of change, designed to get people to like one another more, with a collective action model of change, designed to ignite struggles to achieve intergroup equality?

The problem of negative existentials is one of the classic problems in philosophy of language. Latter-day developments in semantics resolved this problem without our help, but due to accidents of history no one noticed.

Philosophical debates over statistical evidence have long been framed and dominated by L. Jonathan Cohen's Paradox of the Gatecrasher and a related hypothetical example commonly called Prison Yard. These examples, however, raise an issue not discussed in the large and growing literature on statistical evidence – the question of what statistical evidence is supposed to be evidence of. In actual practice, the legal system does not start with a defendant and then attempt to determine if that (...) defendant has committed some unspecified or under-specified act, as these examples appear to suppose. Rather, both criminal and civil litigation start with a sufficiently specified act and then attempt to determine if the defendant has committed it. And when we start with a more fully specified act, the statistics look very different, and these prominent examples no longer present the paradox they are claimed to support. Examining the issue of specification, however, does more than simply undercut the prominent examples in a long and extensive literature. The examination also raises normative issues challenging the legal system's traditional reluctance to base liability on the conjunction of probabilities. (shrink)

Given the tremendous burst of activity in the philosophy of science during the last quarter century, the number of books by trained philosophers dealing with the logic of biology is surprisingly small. Simon’s book resembles Morton Beckner’s The Biological Way of Thought in its comprehensive ambitions: "trying to discover what, if anything, is distinctive about biological science, its concepts, and its mode of explaining." The most obvious difference of the two books is Simon’s long central chapter on "Theories, Models, and (...) the Concept of the Gene," which deals with the history of genetics from Mendel’s predecessors to the successors of Watson and Crick. Beckner paid little explicit attention to the history of biology. Another difference lies in Beckner’s dogged assessment of all problems in the logic of biology from the perspective of what he called the Humean Pattern of Explanation—a detailed and difficult variant of the approach of Hempel, Oppenheim, and Nagel. Simon’s philosophical position is more flexible than Beckner’s. He provides an acceptable review of the literature of the last decade and a half; some of his conclusions are most interesting—even when incompletely supported by his arguments; and the utility of his book is insured by the fact that it is necessary to go back over twelve years to find another with which it can be compared. The first chapter contains a very effective critique of J. J. C. Smart’s thesis that biology is no more an autonomous science than is electrical engineering, but is merely applied physics and chemistry. Smart had argued from the grounds that all biological generalizations implicitly refer to terrestrial evolution and are not truly universal, and Simon demonstrates the general lack of success of all efforts to demonstrate a difference in kind between so-called laws of nature and empirical generalizations of the sort found in biology. The second chapter continues in this same vein, drawing an interesting contrast between phylogenetic explanation in biology and the explanation of individual events in human history, and claiming that ‘explanatory’ status may be granted to accounts which do not meet the requirements of the deductive-nomological model, as in the case of Darwin’s theories of the geographical distribution of plants and animals and the persistence of rudimentary organs. The author’s negative reaction to much of the recent philosophical literature concerning the role of functional analysis in biology seems particularly well placed. Following Hempel, most philosophers writing in the past ten years have regarded the occurrence of the item whose function is in question as the event to be explained. Simon correctly points out that in the biological literature, statements indicating the presence of this item are part of the explanans, usually one component in an explanation of the normal functioning of the organism. He also insists that functional or teleological statements cannot effectively be replaced by nonteleological ones. A functional account is one that relates an entity to the role it plays in an organized system. In the first of several serene non-sequiturs which mar the latter half of this book, Simon insists that the above account shows that the notion of function is essentially an "extrinsic" one and that teleological principles generally cannot be used to account for experience. No better argument than an appeal to Kant’s authority backs up this conclusion. The third chapter deals with the recent history of genetics; its summary makes the claim that "at no time during this history was it correct to say that one model was replaced by another one; rather, the development appears to have been one involving successive correction and refining of earlier conceptions. There has been no revolution: geneticists have always succeeded in either repelling or accommodating critical attacks on the model." The evidence presented earlier in the chapter confers some plausibility on this conclusion, but no more: Simon takes no notice of the controversy surrounding Kuhn and the notion of scientific revolutions, and provides no criteria by which to distinguish "revolutions" from "accommodations." The precise nature of the methodological continuity to be found in the history of genetics is crucial for the view that "biology, or at least genetics, must be regarded as incapable of yielding a complete explanation of the phenomena that come within its purview; if the ultimate principles appealed to are not those of chemistry and physics and hence essentially nonbiological, the explanation cannot be regarded as complete." The text does not clearly indicate the extent to which the author agrees with the statement just quoted; perhaps he only attributes it to "many biologists" impressed by the successes of molecular genetics. It is clear the Simon regards something he calls the "Cartesian attitude" as pervasive in biology. "Biologists are committed to attempting to explain the phenomena of life in terms of the nonliving... The property of being alive or being associated with a living system is simply not treated as a logical primitive within biological science." But this seems to take us back full circle—to the position of Smart, that biology is no more than applied physics and chemistry. Simon disagrees with Smart. How does he stand vis-a-vis this last statement of the Cartesian spirit he finds so pervasive in biology? I think he disagrees with it, but it is very hard to tell. Perhaps the answer is that the resolution of the issue of the autonomy of biology is a pragmatic matter, relative to a complex set of needs and commitments: the sorts of things that determine life styles, political attitudes, and religious points of view, as well as the growth of scientific understanding. The question of the precise configuration of Simon’s pragmatism remains very vague indeed—a consequence of his over use of the style of impersonal attribution rather than direct assertion. Simon says generally sane and familiar things about Biology and the Idea of Progress and about Biology and Ethics. The really startling assertion of the penultimate chapter, that "consciousness" is neither a biological nor a behavioral predicate, and that its foundations are essentially moral and legal, is unfortunately supported by no argument whatsoever. Instead, the reader is urged to examine two of the author’s previous articles.—E. M. (shrink)

Negative compatibility effects in the masked-prime paradigm are usually obtained when primes are masked effectively. With ineffective masks—and primes above the perceptual threshold—positive compatibility effects occur. We investigated whether this pattern reflects a causal relationship between conscious awareness and low-level motor control, or whether it reflects the fact that both are affected in the same way by changes in physical stimulus attributes. In a 5-session perceptual learning task, participants learned to consciously identify masked primes. However, they showed unaltered NCEs (...) that were not different from those produced by participants in a control group without equivalent perceptual learning. A control experiment demonstrated that no NCEs occur when prime identification is made possible by ineffective masking. The results suggest that perceptual awareness and low-level motor control are affected by the same factors, but are fundamentally independent of each other. (shrink)

The paradigm of referent tracking is based on a realist presupposition which rejects so-called negative entities (congenital absent nipple, and the like) as spurious. How, then, can a referent tracking-based Electronic Health Record deal with what are standardly called ‘negative findings’? To answer this question we carried out an analysis of some 748 sentences drawn from patient charts and containing some form of negation. Our analysis shows that to deal with these sentences we need to introduce a new (...) ontological relationship between a particular and a universal, which holds when no instance of the universal has a specific qualified ontological relation with the particular. This relation is found to be able to accommodate nearly all occurrences of negative findings in the examined sample, in ways which involve no reference to negative entities. (shrink)

The swamping problem is to explain why knowledge is epistemically better than true belief despite being no more true, if truth is the sole fundamental epistemic value. But Carter and Jarvis argue that the swamping thesis at the heart of the problem ‘is problematic whether or not one thinks that truth is the sole epistemic good’. I offer a counterexample to this claim, in the form of a theory of epistemic value for which the swamping thesis is not (...) problematic: evidence monism. Then I argue that another kind of response to the swamping problem given by Sylvan 2018 does not escape the problem unscathed, because it is not only instrumentalism that gives rise to the swamping problem. The upshot is that, given a standard account of fundamental value, the swamping problem favours evidence monism over truth monism. (shrink)

Our limited a priori-reasoning skills open a gap between our finding a proposition conceivable and its metaphysical possibility. A prominent strategy for closing this gap is the postulation of ideal conceivers, who suffer from no such limitations. In this paper I argue that, under many, maybe all, plausible unpackings of the notion of ideal conceiver, it is false that ideal negative conceivability entails possibility.

In this paper we consider the problem of how to measure the strength of statistical evidence from the perspective of evidence amalgamation operations. We begin with a fundamental measurement amalgamation principle : for any measurement, the inputs and outputs of an amalgamation procedure must be on the same scale, and this scale must have a meaningful interpretation vis a vis the object of measurement. Using the p value as a candidate evidence measure, we examine various commonly (...) used approaches to amalgamation of evidence across similar studies, including standard forms of meta-analysis. We show that none of these methods satisfies MAP. Thus an underlying measurement problem remains. We argue that a successful approach to evidence amalgamation necessitates a solution to the problem of evidence measurement, and we suggest some lines of reasoning that might guide further work towards this end.

People implicitly associate different emotions with different locations in left-right space. Which aspects of emotion do they spatialize, and why? Across many studies people spatialize emotional valence, mapping positive emotions onto their dominant side of space and negative emotions onto their non-dominant side, consistent with theories of metaphorical mental representation. Yet other results suggest a conflicting mapping of emotional intensity (a.k.a., emotional magnitude), according to which people associate more intense emotions with the right and less intense emotions with the (...) left — regardless of their valence; this pattern has been interpreted as support for a domain-general system for representing magnitudes. To resolve the apparent contradiction between these mappings, we first tested whether people implicitly map either valence or intensity onto left-right space, depending on which dimension of emotion they attend to (Experiments 1a, b). When asked to judge emotional valence, participants showed the predicted valence mapping. However, when asked to judge emotional intensity, participants showed no systematic intensity mapping. We then tested an alternative explanation of findings previously interpreted as evidence for an intensity mapping (Experiments 2a, b). These results suggest that previous findings may reflect a left-right mapping of spatial magnitude (i.e., the size of a salient feature of the stimuli) rather than emotion. People implicitly spatialize emotional valence, but, at present, there is no clear evidence for an implicit lateral mapping of emotional intensity. These findings support metaphor theory and challenge the proposal that mental magnitudes are represented by a domain-general metric that extends to the domain of emotion. (shrink)

In our 2021 paper, “Houston: Do we have a problem?”, we argued that contra popular belief, there is no conflict between existence of ETI and theism in general and Christian theism in particular. In this paper we argue further that the existence of ETI, especially ETI who are sophisticated enough to travel space, is evidence for theism. That is, ETI confirms the hypothesis that God exists over its naturalist competitor.

La représentation de la Crucifixion dans de grandes compositions aux tympans des églises est un phénomène tardif dans l’Occident médiéval : elle pose le problème de l’intégration de l’iconographie monumentale dans le contexte religieux et homilétique. Les premiers exemples de la fin du XIe siècle étaient liés aux hérésies cathare et petrobrusienne du sud de la France1. Au XIVee siècle, la diffusion du thème rend plus difficile une approche globale de la question. Dans le contexte précis et bi...

In this paper, I provide a new argument in support of a concessive response to the Ravens Paradox. The argument I offer stems from Mark Schroeder's Gricean explanation for why existential judgments about normative reasons for action are unreliable. In short, I argue that Schroeder's work suggests that, in the case of the Ravens Paradox, people are running together the issue of what's assertible about evidence with what's true about evidence. Once these issues are pulled apart, we have (...) reason to think that the negative existential judgment about evidence that drives the Ravens Paradox is mistaken, and thus that there is in fact no paradox here at all.

A number of philosophers have argued that causation is not an objective feature of the microphysical world but rather is a perspectival phenomenon that holds only between “coarse-grained” entities such as those that figure in the special sciences. This view seems to pose a problem for arguments for physicalism that rely on the alleged causal completeness of physics. In this paper, I address this problem by arguing that the completeness of physics has two components, only one of which (...) is causal. These two components of completeness can be used in an argument for physicalism that is supported by strong inductive evidence even in the absence of microphysical causation. (shrink)

The Problems of Philosophy is a 1912 book by Bertrand Russell, in which Russell attempts to create a brief and accessible guide to the problems of philosophy. Focusing on problems he believes will provoke positive and constructive discussion, Russell concentrates on knowledge rather than metaphysics: If it is uncertain that external objects exist, how can we then have knowledge of them but by probability. There is no reason to doubt the existence of external objects simply because of sense data. Russell (...) guides the reader through his famous 1910 distinction between knowledge by acquaintance and knowledge by description and introduces important theories of Plato, Aristotle, René Descartes, David Hume, John Locke, Immanuel Kant, Georg Wilhelm Friedrich Hegel and others to lay the foundation for philosophical inquiry by general readers and scholars alike. "In the following pages I have confined myself in the main to those problems of philosophy in regard to which I thought it possible to say something positive and constructive, since merely negative criticism seemed out of place. For this reason, theory of knowledge occupies a larger space than metaphysics in the present volume, and some topics much discussed by philosophers are treated very briefly, if at all. (shrink)

The infinite time Turing machine analogue of Post's problem, the question whether there are semi-decidable supertask degrees between 0 and the supertask jump 0∇, has in a sense both positive and negative solutions. Namely, in the context of the reals there are no degrees between 0 and 0∇, but in the context of sets of reals, there are; indeed, there are incomparable semi-decidable supertask degrees. Both arguments employ a kind of transfinite-injury construction which generalizes canonically to oracles.

In this paper, I have two primary goals. First, I show that the causal-based story approach in A hybrid formal theory of arguments, stories and criminal evidence is ill suited to negative causation. In the literature, the causal-based approach requires that hypothetical stories be causally linked to the explanandum. Many take these links to denote physical or psychological causation, or temporal precedence. However, understanding causality in those terms, as I will show, cannot capture cases of negative causation, (...) which are of interest to the Law. In keeping with this, I also discuss some of the difficulties Hybrid Theory invites by remaining silent on the nature of the causal links. In my second aim, I sketch a way for Hybrid Theory to overcome this problem. By replacing the original, underlying causal structure with contrastive causation in the law, Hybrid Theory can represent reasoning in which the evidence that is appealed to is causally linked via negative causation to the explananda.

Automatic detection of information changes in the visual environment is crucial for individual survival. Researchers use the oddball paradigm to study the brain’s response to frequently presented stimuli and occasionally presented stimuli. The component that can be observed in the difference wave is called visual mismatch negativity, which is obtained by subtracting event-related potentials evoked by the deviant from ERPs evoked by the standard. There are three hypotheses to explain the vMMN. The sensory fatigue hypothesis considers that weakened neural activity (...) caused by repetition results in decreased ERPs of the standard. The memory trace hypothesis proposes that vMMN results from increased responses to the deviant. The predictive coding hypothesis attributes the difference to enhanced responses for deviants and suppression for standards. However, when distinguishing between these effects, previous researchers did not consider the effect of low-level features on the vMMN. In this experiment, we used face sequences composed of different emotions and presented an oddball sequence, a reverse oddball sequence, and an equiprobable sequence to participants. The deviant of the oddball sequence was subtracted from the standard of the oddball sequence, the reverse oddball sequence, and the same type of stimulus of the equiprobable sequence to get oddball-vMMN, reverse oddball-vMMN, and equiprobable-vMMN, respectively. The results showed no significant difference between vMMN2 and vMMN3 in 100–350 ms following stimulus onset, while the vMMN effect was significant, indicating that the probability of the standard did not affect vMMN, which supported the memory trace hypothesis. Additionally, the fearful-related vMMN were more negative than the neutral-related vMMN within the range of 100–150 ms, suggesting a negative bias. We analyzed the source location of different vMMNs. There was no significant difference in brain regions between different vMMNs. Time-frequency analysis showed that the deviant had stronger theta-band oscillatory than the standard. However, there was no difference between vMORs2 and vMORs3, indicating that vMORs reflect an enhanced response to the deviant in terms of neural oscillation, supporting the memory trace hypothesis.
