Abstract In this paper I present a short outline of an Indicativity Theory of Knowledge, for the cases of Perceptual Knowledge and Knowledge by Memory. I explain the main rationale for a token-indicativity approach, and how it is fleshed out precisely in terms of chances. I elaborate on the account of the value of knowledge it provides, and what that value is. I explain why, given the rationale of conceiving Knowledge as token indicativity, separate sub-accounts in terms of chances should (...) be extracted for the different modes of Knowledge, elaborating on the common core of high token-indicativity. In the main section that outlines the account of Perceptual Knowledge, the main Indicativity condition is presented, as are the main condition of in what sense high token indicativity should yields high chance, the important Discriminability condition, and its associated Contrast Class.

Discrimination laws usually prohibit discrimination based on some traits, like race, caste, and sex, and not on others, like sports team allegiance. Should socioeconomic class be included among the protected traits? We examine an argument for the view that it should which leads to the conclusion that both direct and indirect socioeconomic discrimination should be prohibited by the state. The argument has three premises: (1) direct paradigmatic discrimination should be prohibited by law; (2) if direct paradigmatic discrimination should be (...) prohibited by law, then so should direct socioeconomic discrimination; and (3) where direct discrimination based on a certain trait should be prohibited by law, so should indirect discrimination on the basis of the same trait. Since we assume most readers will accept (1), the paper is largely devoted to the defense of (2) and (3). The outlawing of direct socioeconomic discrimination would involve an adjustment of the political and legal status quo, but we argue that it should nevertheless be implemented. By contrast, a prohibition on indirect socioeconomic discrimination would require a radical change to the way in which our societies are structured, because many of our laws, policies, and practices systematically (re)produce inequality to the disproportionate detriment of the poor. Our main aim, therefore, is not to defend the prohibition of indirect socioeconomic discrimination, but to show that most people’s views about discrimination are in deep tension with their attitude to current law. Resolving this tension would require for most of us to revise our beliefs either about whether indirect socioeconomic discrimination should be prohibited or about (1)–(3). One might reject the view that law should prohibit socioeconomic discrimination and still accept this claim about a deep tension in most people’s views on discrimination. (shrink)

The quantization error in a fixed-size Self-Organizing Map (SOM) with unsupervised winner-take-all learning has previously been used successfully to detect, in minimal computation time, highly meaningful changes across images in medical time series and in time series of satellite images. Here, the functional properties of the quantization error in SOM are explored further to show that the metric is capable of reliably discriminating between the finest differences in local contrast intensities and contrast signs. While this capability of the (...) QE is akin to functional characteristics of a specific class of retinal ganglion cells (the so-called Y-cells) in the visual systems of the primate and the cat, the sensitivity of the QE surpasses the capacity limits of human visual detection. Here, the quantization error in the SOM is found to reliably signal changes in contrast or colour when contrast information is removed from or added to the image, but not when the amount and relative weight of contrast information is constant and only the local spatial position of contrast elements in the pattern changes. While the RGB Mean reflects coarser changes in colour or contrast well enough, the SOM-QE is shown to outperform the RGB Mean in the detection of single-pixel changes in images with up to five million pixels. This could have important implications in the context of unsupervised image learning and computational building block approaches to large sets of image data (big data). (shrink)

In this paper, I provide a probabilistic account of factual knowledge, based on the notion of chance, which is a function of an event given a prior history. This account has some affinity with my chance account of token causation, but it neither relies on it nor presupposes it. Here, I concentrate on the core cases of perceptual knowledge and of knowledge by memory. The analysis of knowledge presented below is externalist. The underlying intuition guiding the treatment of knowledge in (...) this paper is that knowledge boils down to high token discriminative indicativeness. Type indicativeness or type discriminability are neither necessary nor sufficient for knowledge: the token aspect comes out in the strong dependence on the specific circumstances and chances of the case. The main condition of the first section, the indicativity condition, properly refined, yields pertinent indicativity as a main constituent. Very roughly, it involves the chance of the content clause p being higher given the subject's believing that p than otherwise. The discriminability condition in question captures the sense of discriminability appropriate for knowledge and yield the indicativity condition: it is an extension of the indicativity condition KI. Roughly, the subject’s ability to discriminate the object in front of her being red from its being green is captured by holding fixed, in the indicativity condition, the condition “the object in front of her is red or green.” A major element in the analysis is the so-called Contrast Class, which governs the scope of discriminability. This is the class of features that have to be taken into account in the discriminability condition, and it is characterized by two constraints. Very roughly, according to the first constraint, for a feature to be in the contrast class, it must not represent a sub-type of the predicate in the content clause. According to the second constraint, which is a central condition with many implications, the chance that the object specified in the content clause has a feature represented in the contrast class must not under the circumstances be too low. This constraint, within the framework of the discriminability condition, brings out a major constitutive aspect of knowledge: knowledge amounts to a limited vulnerability to mistakes of the belief in question under the circumstances at hand. The contrast class plays a major role in my treatment of skepticism. The second constraint on the Contrast Class together with the VHP condition below bring out precisely the way in which perceptual knowledge is fallible. (shrink)

Wason's standard 2-4-6 task requires discovery of a single rule and leads to around 20% solutions, whereas the dual goal (DG) version requires discovery of two rules and elevates solutions to over 60%. We report an experiment that aimed to discriminate between competing accounts of DG facilitation by manipulating the degree of complementarity between the to-be-discovered rules. Results indicated that perfect rule complementarity is not essential for task success, thereby undermining a key tenet of the goal complementarity account of DG (...) facilitation. The triple heterogeneity account received a good degree of support since more varied triple exploration was associated with facilitatory DG conditions, in line with this account's prediction that task success is associated with the creative search of the problem space. The contrast class account (an extension of Oaksford & Chater's, 1994, iterative counterfactual model) was also corroborated in that the generation of descending triples was demonstrated to be the dominant predictor of DG success. We focus our discussion on conceptual ideas relating to the way in which iterative counterfactual testing and contrast class identification may work together to provide a powerful basis for effective hypothesis testing.

I argue that causation is a contrastive relation: c-rather-than-C* causes e-rather-than-E*, where C* and E* are contrast classes associated respectively with actual events c and e. I explain why this is an improvement on the traditional binary view, and develop a detailed definition. It turns out that causation is only well defined in ‘uniform’ cases, where either all or none of the members of C* are related appropriately to members of E*.

Changing and often class-dependent non-stationarities of signals are a big challenge in the transfer of common findings in cognitive workload estimation using Electroencephalography (EEG) from laboratory experiments to realistic scenarios or other experiments. Additionally, it often remains an open question whether actual cognitive workload reflected by brain signals was the main contribution to the estimation or discriminative and class-dependent muscle and eye activity, which can be secondary effects of changing workload levels. Within this study, we investigated a novel (...) approach to spatial filtering based on beamforming adapted to changing settings. We compare it to no spatial filtering and Common Spatial Patterns (CSP). We used a realistic maneuvering task, as well as an auditoryn-backsecondary task on a tugboat simulator as two different conditions to induce workload changes on professional tugboat captains. Apart from the typical within condition classification, we investigated the ability of the different classification methods to transfer between then-backcondition and the maneuvering task. The results show a clear advantage of the proposed approach over the others in the challenging transfer setting. While no filtering leads to lowest within-condition normalized classification loss on average in two scenarios (22 and 10%), our approach using adaptive beamforming (30 and 18%) performs comparably to CSP (33 and 15%). Importantly, in the transfer from one to another setting, no filtering and CSP lead to performance around chance level (45 to 53%), while our approach in contrast is the only one capable of classifying in all other scenarios (34 and 35%) with a significant difference from chance level. The changing signal composition over the scenarios leads to a need to adapt the spatial filtering in order to be transferable. With our approach, the transfer is successful due to filtering being optimized for the extraction of neural components and additional investigation of their scalp patterns revealed mainly neural origin. Interesting findings are that rather the patterns slightly change between conditions. We conclude that the approaches with low normalized loss depend on eye and muscle activity which is successful for classification within conditions, but fail in the classifier transfer since eye and muscle contributions are highly condition-specific.

In this paper the arguments for optimal data selection and the contrast class account of negations in the selection task and the conditional inference task are summarised, and contrasted with the matching bias approach. It is argued that the probabilistic contrast class account provides a unified, rational explanation for effects across these tasks. Moreover, there are results that are only explained by the contrast class account that are also discussed. The only major anomaly is (...) the explicit negations effect in the selection task (Evans, Clibbens, & Rood, 1996), which it is argued may not be the result of normal interpretative processes. It is concluded that the effects of negation on human reasoning provide good evidence for the view that human reasoning processes may be rational according to a probabilistic standard. (shrink)

In an influential paper, Wendy Parker argues that agreement across climate models isn’t a reliable marker of confirmation in the context of cutting-edge climate science. In this paper, I argue that while Parker’s conclusion is generally correct, there is an important class of exceptions. Broadly speaking, agreement is not a reliable marker of confirmation when the hypotheses under consideration are mutually consistent—when, e.g., we’re concerned with overlapping ranges. Since many cutting-edge questions in climate modeling require making distinctions between mutually (...) consistent hypotheses, agreement across models will be generally unreliable in this domain. In cases where we are only concerned with mutually exclusive hypotheses, by contrast, agreement across climate models is plausibly a reliable marker of confirmation. (shrink)

Commentary of Justin Garson, "Madness and idiocy: Reframing a basic problem of philosophy of psychiatry." Philosophy, Psychiatry, & Psychology.

In contrast to popular presumptions and prior research on women ofthe “postfeminist” generation, this study found anappreciation for recent historicalchanges in women’s opportunities, and an awareness of persisting inequalities and discrimination. The findings reveal support for feminist goals, coupled with ambiguity about the concept offeminism. Although some of the women could be categorized alonga continuum of feminist identification, half were “fence-sitters” or were unable to articulate a position. There were variations in perspectives amongthose with different life experiences, as well (...) as by racial and class background. (shrink)

1. Contextualism seeks to acknowledge the power of sceptical arguments while permitting to be true at least some of the assertions of knowledge and justification we commonly make. It seems to me now just as if I am in an office in Edinburgh. According to the sceptic the claim that I am in fact in an office in Edinburgh is unjustified, since there is no reason I can give for this belief that is not also consistent with (or undermined by) (...) the alternative hypothesis that I am in fact on a beach in Hawaii being deceived by an evil demon into thinking that I am in an office in Edinburgh.

We report two studies on the effect of implicitly versus explicitly conveying affirmation and denial problems about conditionals. Recently Evans and Handley (1999) and Schroyens et al. (1999b, 2000b) showed that implicit referencing elicits matching bias: Fewer determinate inferences are made, when the categorical premise (e.g., B) mismatches the conditional's referred clause (e.g., A). Also, the effect of implicit affirmation (B affirms not-A) is larger than the effect of implicit denial (B denies A). Schroyens et al. hypothesised that this interaction (...) is due to uncertainty in the case-wise affirmation of the contrast class of negated elements involved in implicit affirmations. In Experiment 1 we tested this hypothesis by manipulating the set size of the conditional clauses. The results confirm that binary sets, where the contrast class is a singleton, eliminate the differential effect of implicit affirmation and denial. With non-binary sets the interaction is not modulated by the scope of the contrast class (3, 5, 9 elements). Experiment 2 further investigated the role of contrast classes by using class inclusion to construct implicit affirmations (Mammal vs Mammal or Monkey) and implicit denial (No-Mammal vs Mammal or Monkey), in addition to the standard implicit problems mediated by contrast-class inclusion [(No-)Mammal/No-Mammal; Reptile; Snake). Findings indicate that class inclusion (Mammal/Monkey; Reptile/ Snake) only marginally affects performance, and is independent of the type of problem. This would suggest that the implicitness problem-type interaction is dependent on constructing contrast classes. However, the experiment failed to replicate the interaction, even on the subset of problems repeating the abstract letter/number format of Experiment 1. Moreover, with the natural binary set-sizes (vowels/consonants) the implicitness effect was eliminated entirely. (shrink)

Now more than ever it is clear that the global economy needs to be assessed and governed from a moral point of view. Such moral assessment can, however, come in at least two quite different forms. Political philosophers have tended to focus on a range of issues (e.g. poverty, human rights, or general distributive justice) whose basic moral importance is “external” to and wholly independent of how the global economy is socially organized. The result has been relative neglect of a (...) quite different class of “internal” moral issues, which do in various ways depend on the complex legal and social relations that now organize the global economic scene. These include a dizzying array of politically important but poorly understood fairness concerns—concerns such as “non-discrimination,” “special and differential treatment,” “fair trade,” “fair play,” “fair competition,” “level playing fields,” “equitable growth,” “fair wages,” and “exploitation.” My aim in this discussion is to suggest a framework for understanding how several such fairness notions might be systematically connected and have an internal rather than external character. Specifically, I suggest that the content and internal nature of several such fairness notions can be explicated in terms of a more fundamental idea of “structural equity.” From the point of view of political philosophy, the issue turns on the sorts of principles that might ground moral assessment of the global economy. External principles are justified and apply quite independently of what the global economy and its social organization happens to be like. Humanitarian principles are a natural example: in asking whether or not the current global economy is set up so as to bring as many people as possible out of poverty, the assumed goal of poverty reduction can be seen as important and morally necessary quite independently of how the global economy is institutionally organized, and indeed independently of its very existence. Internal principles, by contrast, are not justified, and do not apply, independently of the global economy and its organizing institutions.. (shrink)

The traditional Bayesian qualitative account of evidential support (TB) takes assertions of the form 'E evidentially supports H' to affirm the existence of a two-place relation of evidential support between E and H. The analysans given for this relation is $C(H,E) =_{def} Pr(H\arrowvertE) \models Pr(H)$ . Now it is well known that when a hypothesis H entails evidence E, not only is it the case that C(H,E), but it is also the case that C(H&X,E) for any arbitrary X. There is (...) a widespread feeling that this is a problematic result for TB. Indeed, there are a number of cases in which many feel it is false to assert 'E evidentially supports H&X', despite H entailing E. This is known, by those who share that feeling, as the 'tacking problem' for Bayesian confirmation theory. After outlining a generalization of the problem, I argue that the Bayesian response has so far been unsatisfactory. I then argue the following: (i) There exists, either instead of, or in addition to, a two-place relation of confirmation, a three-place, 'contrastive' relation of confirmation, holding between an item of evidence E and two competing hypotheses H₁ and H₂. (ii) The correct analysans of the relation is a particular probabilistic inequality, abbreviated C(H₁, H₂, E). (iii) Those who take the putative counterexamples to TB discussed to indeed be counterexamples are interpreting the relevant utterances as implicitly contrastive, contrasting the relevant hypothesis H₁ with a particular competitor H₂. (iv) The probabilistic structure of these cases is such that ∼C(H₁, H₂, E). This solves my generalization of the tacking problem. I then conclude with some thoughts about the relationship between the traditional Bayesian account of evidential support and my proposed account of the three-place relation of confirmation. (shrink)

The differentiation of trait anxiety and depression in nonclinical and clinical populations is addressed. Following the tripartite model, it is assumed that anxiety and depression share a large portion of negative affectivity, but differ with respect to bodily hyperarousal and anhedonia. In contrast to the tripartite model, NA is subdivided into worry and dysthymia, which leads to a four-variable model of anxiety and depression encompassing emotionality, worry, dysthymia, and anhedonia. Item-level confirmatory factor analyses and latent class cluster analysis (...) based on a large nation-wide representative German sample substantiate the construct validity of the model. Further evidence concerning convergent and discriminant validity with respect to related constructs is obtained in two smaller nonclinical and clinical samples. Factors influencing the association between components of anxiety and depression are discussed. (shrink)

In political philosophy and in economics, unfair inequality is usually assessed between individuals, nowadays often on luck-egalitarian grounds. You have more than I do and that's unfair. By contrast, in epidemiology and sociology, unfair inequality is traditionally assessed between groups. More is concentrated among people of your class or race than among people of mine, and that's unfair. I shall call this difference the egalitarian ‘divorce’. Epidemiologists, and their ‘divorce lawyers’ Paula Braveman, Norman Daniels, and Iris Marion Young, (...) explain that not every inequality between individuals is an inequity. Only inequality between social status groups is unfair. Only such inequality stems from problems like partiality, discrimination, oppression, inequality-related population health problems, and unfair distribution of prospects. And it alone is actionable. By contrast, inequality between individuals, e.g. in longevity, is natural, inevitable, less important, or otherwise less informative — not unjust. In ‘divorce trial’ mode, I respond to epidemiologists that group inequalities lack the intrinsic disvalue that they ascribe them. They may be instrumentally or contingently bad or wrong, not essentially so. I then shift to ‘remarriage’: although group inequalities lack intrinsic badness or wrongness, for multiple reasons they remain useful to measure. (shrink)

To successfully learn using open Internet resources, students must be able to critically search, evaluate and select online information, and verify sources. Defined as critical online reasoning, this construct is operationalized on two levels in our study: the student level using the newly developed Critical Online Reasoning Assessment, and the online information processing level using event log data, including gaze durations and fixations. The written responses of 32 students for one CORA task were scored by three independent raters. The resulting (...) score was operationalized as “task performance,” whereas the gaze fixations and durations were defined as indicators of “process performance.” Following a person-oriented approach, we conducted a process mining analysis, as well as a latent class analysis to test whether—following the dual-process theory—the undergraduates could be distinguished into two groups based on both their process and task performance. Using PM, the process performance of all 32 students was visualized and compared, indicating two distinct response process patterns. One group of students, defined as “strategic information processers,” processed online information more comprehensively, as well as more efficiently, which was also reflected in their higher task scores. In contrast, the distributions of the process performance variables for the other group, defined as “avoidance information processers,” indicated a poorer process performance, which was also reflected in their lower task scores. In the LCA, where two student groups were empirically distinguished by combining the process performance indicators and the task score as a joint discriminant criterion, we confirmed these two COR profiles, which were reflected in high vs. low process and task performances. The estimated parameters indicated that high-performing students were significantly more efficient at conducting strategic information processing, as reflected in their higher process performance. These findings are so far based on quantitative analyses using event log data. To enable a more differentiated analysis of students’ visual attention dynamics, more in-depth qualitative research of the identified student profiles in terms of COR will be required. (shrink)

The increasing prominence of men’s studies in the academic panorama has allowed for further investigation not only on women’s, but also on men’s literary identities. The Ibis Trilogy by Amitav Ghosh offers new insights on the subject by staging several queer masculinities. The present essay analyses the non-conforming identity of Kesri Singh from the perspective of men’s studies. Firstly, the essay compares and contrasts the socially imposed masculinity with Kesri’s divergent one. Secondly, it highlights the strategy deployed by the warrior (...) in order to protect his psychological and physical integrity in a toxic environment. Given the strong historical background of the novels, references are provided to account for the patriarchal context in which Kesri develops. Further sources of discrimination such as race and class are also explored, according to an intersectional feminist approach. Thus, it will be proved that a male gender related discourse covers ample narrative space in the Trilogy; it also reflects the critical opposition by Ghosh to the Western colonialism and Indian caste division. Moreover, it will be exposed the manipulative use of the male gender as an instrument to enforce colonialism and classism. Therefore, the Trilogy presents masculinity as a highly debatable, multifaceted notion which undergoes a negotiation in meaning throughout the novels. This premise leads to a broader definition of the concept, which provides a new, significant viewpoint on the subject. (shrink)

Many perception and processing effects of the lexical status of tone have been found in behavioral, psycholinguistic, and neuroscientific research, often pitting varieties of tonal Chinese against non-tonal Germanic languages. While the linguistic and cognitive evidence for lexical tone is therefore beyond dispute, the word prosodic systems of many languages continue to escape the categorizations of typologists. One controversy concerns the existence of a typological class of “pitch accent languages,” another the underlying phonological nature of surface tone contrasts, which (...) in some cases have been claimed to be metrical rather than tonal. We address the question whether the Sequence Recall Task, which has been shown to discriminate between languages with and without word stress, can distinguish languages with and without lexical tone. Using participants from non-tonal Indonesian, semi-tonal Swedish, and two varieties of tonal Mandarin, we ran SRTs with monosyllabic tonal contrasts to test the hypothesis that high performance in a tonal SRT indicates the lexical status of tone. An additional question concerned the extent to which accuracy scores depended on phonological and phonetic properties of a language’s tone system, like its complexity, the existence of an experimental contrast in a language’s phonology, and the phonetic salience of a contrast. The results suggest that a tonal SRT is not likely to discriminate between tonal and non-tonal languages within a typologically varied group, because of the effects of specific properties of their tone systems. Future research should therefore address the first hypothesis with participants from otherwise similar tonal and non-tonal varieties of the same language, where results from a tonal SRT may make a useful contribution to the typological debate on word prosody.

Intersectionality is the notion that concerns the complexity of the experiences of individuals in virtue of their belonging to multiple socially significant categories. One of its main insights is that the way society is structured around categories such as gender, race, sexuality, class, etc., produces distinctive and specific forms of discrimination and privilege for groups in the intersections. In this paper, we suggest conceiving intersectionality as a general metaphysical framework wherein specific claims to the effect that the experiences of (...) discrimination of Black women, among others, can be fruitfully formulated and examined. The main claim is that intersectional experiences emerge from the conjunction of social categories when social structures make them relevant vis-à-vis discrimination and privilege. We then argue that our view has three main virtues: metaphysical neutrality, explanatory flexibility and methodological openness. Explaining these virtues will allow us to contrast our proposal with alternatives from the recent literature. (shrink)

The quality of early childhood education and care (ECEC) is important for children’s development. One instrument that was developed to assess an aspect of ECEC quality is the Classroom Assessment Scoring System for pre-kindergarten children (CLASS Pre-K). We examined the factorial validity of the instrument using data from 177 German preschool classrooms. The three-factor teaching through interaction model (Hamre et al., 2013) was contrasted to a one-factor, a two-factor, and a bifactor model as proposed by Hamre et al. (2014). (...) Our results indicated that the three-factor structure with the domains of emotional support, classroom organization, and instructional support fit the data best. The fit of the teaching through interaction model was satisfying after adding a cross-loading of the dimension language modeling on emotional support, and two correlated residuals. Evidence of convergent and discriminant validity are provided. In terms of factor structure and pattern score comparisons, the results were similar to previous U.S. and German studies. The discussion concerns the justifiability of the factor model revisions and draws directions for further research. We concluded that our study offers further evidence of the applicability of the CLASS Pre-K for the assessment of teacher-child interaction quality in the German context. (shrink)

To apply reinforcement learning to difficult classes such as real-environment learning, we need to use a method robust to perceptual aliasing problem. The exploitation-oriented methods such as Profit Sharing can deal with the perceptual aliasing problem to a certain extent. However, when the agent needs to select different actions at the same sensory input, the learning efficiency worsens. To overcome the problem, several state partition methods using history information of state-action pairs are proposed. These methods try to convert a POMDP (...) environment into an MDP environment, and thus they are sometimes very useful. However, their computation cost is very high especially in large state spaces. In contrast, memory-less approaches try to escape from the aliased states by outputting actions stochastically. However, these methods output actions stochastically even in unaliased states, and thus the learning efficiency is bad. If we desire to guarantee the rationality in POMDPs, it is efficient to output actions stochastically only in the aliased states and to output one action deterministically in the other unaliased states. Hence, to discriminate between aliased states and unaliased states, the utilization of χ² -goodness-of-fit test is proposed by Miyazaki et al. They point out that, in aliased states, the distributions of the state transitions by random search and a particular policy are different. This difference doesn't occur owing to non-deterministic actions. Hence, if the agent can collect enough samples to implement the test, the agent can distinguish between aliased states and unaliased states well. However, such a test needs a large amount of data, and it's a problem how the agent collects samples without worsening learning efficiency. If the agent uses random search in the course of learning, the learning efficiency worsens especially in unaliased states. Therefore, in this research, we propose a new method called Extended On-line Profit Sharing with Judgement (EOPSwJ) to detect important incomplete perception, which doesn't need large computation cost and numerous samples. We use two criterions for detecting important incomplete perceptions to attain a task. One is the rate of transitions to each state, and the other is the deterministic rate of actions. We confirm the availability of EOPSwJ using two simulations. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Studies in Advaita Vedanta: Towards an Advaita Theory of ConsciousnessChakravarthi Ram-PrasadStudies in Advaita Vedanta: Towards an Advaita Theory of Consciousness. By Sukharanjan Saha. Kolkata: Jadavpur University, 2004. Pp. 231.Studies in Advaita Vedanta: Towards an Advaita Theory of Consciousness, by Sukhar-anjan Saha, is a collection of papers each of which has something to say about consciousness in Advaita, although some of the papers have a rather tenuous connection to (...) this theme. Saha brings to bear a lifetime of study of Advaita and its philosophical contexts in these essays. The one notable lacuna in his approach is the tendency to ignore virtually all contemporary literature on Advaita, and to concentrate almost entirely on the original Sanskrit texts themselves—although he is clearly at home in a variety of modern philosophical techniques. His views are, in themselves, interesting and carefully spelled out.In "The Many Faces of the 'I,' " Saha draws on well-known uses of aham in Śaṅkara, Vācaspati, and Padmapāda to draw the larger conclusion that Advaita is willing to allow for multiple, context-variant senses of 'I,' in contrast to both a Naiyāyika like Gadhādhara and Western thinkers like Husserl."Advaita Analysis of Suffering" is an elegant and surprising essay. Much of it appears to be a fairly general survey of the manner in which different Hindu and Buddhist thinkers identify a positive cognitive error in understanding reality—avidyā—as the cause of suffering. But Saha notes that the classical consensus on suffering is not an empirical statement; there are ordinary success stories, after all. He then ingeniously uses this fact to show that suffering is something structural to existence. Śaṅkara's example of someone who feels "I am fair-complexioned" is a smug indication of the suffering brought to bear on others who are not, in a society that favors fair complexion. Suffering, Saha argues, is socially relative; it relates to value structures more than mere physical discomfort. If all were of the highest or lowest varna, there would be neither pride nor striving, neither bragging nor lamenting. The metaphysical discussion on suffering, it turns out, is really a commentary on Hindu society.Saha heroically—in the light of modern, especially Western scholarship, which sees Śaṅkara as an arch-conservative proponent of brahminical values—tends to see the Advaitin as a social reformer. In the essay above, he sees ś an.kara as teaching precisely the social lesson against discrimination when he talks of suffering. Saha returns to this theme in "Śaṅkara and Varna Distinctions in Hinduism." He puts forward the argument that since Śaṅkara held that all social distinctions were not ultimate (pāramārthika), and since class/varna distinctions are social ones while liberating knowledge is ultimate, varna is irrelevant to liberation. How those traditionally excluded from brahminical philosophy will respond to this generosity is another matter. [End Page 107]In "Inner Sense and Higher Order Consciousness," Saha usefully explains how Nyāya takes an awareness of awareness to be a matter of inner sense, while Advaita denies this. It is sometimes hard to follow him through the essay, as it is not always clear what is being argued. But the contours of the standard Nyāya and Advaita positions on putative higher-order consciousness are laid out competently. The Nyāya position is clear enough, in that the higher-order awareness is an inner perception, with the mind playing the role of an 'inner' organ for the self. So the self becomes conscious of an object through the mind, and that act of consciousness itself becomes an object of the mind; in the latter instance, the mind functions to generate a higher-order consciousness, taking the first mental state as its object. This is relatively clear, but puts a great burden on Nyāya to give a cogent theory of mind, such that the idea of the mind as an inner sense organ becomes persuasive. But this challenge lies beyond the scope of Saha's essay.Gradually, Saha's argument emerges. Advaita takes the mind to be separate from consciousness, which is the untouched ātman. So, there may well be mental... (shrink)

Anti‐discrimination laws draw a distinction between two kinds of discrimination by non‐state actors. Intimate choices are protected even if they are morally wrong. For example, even if it is morally wrong to discriminate on the basis of race in deciding whom to date, marry or befriend, anti‐discrimination laws permit these acts. By contrast, commercial decisions are commonly regulated. I argue that the reasons for regulating commercial decisions also extend to an intermediate case, commercial facilitators of marriage choices. In the (...) context of the caste system, I argue that commercial facilitators should be banned from allowing customers to filter by caste. The argument is based on two considerations. First, this could mitigate the harmful effects of such discriminatory marriages choices in the (re)production of the oppressive caste system. Second, even if the ban fails in changing behaviour, it serves as an expressive goal of communicating the state's opposition to the caste system. (shrink)

Can an act harm someone—a future someone, someone who does not exist yet but will—if that person would never exist but for that very action? This is one question raised by the non-identity problem. Many would argue that the answer is No: an action harms someone only insofar as it is worse for her, and an action cannot be worse for someone if she would not exist without it. The first part of this paper contends that the plausibility of the (...) ‘no harm’ argument stems from an equivocation. The second half argues for an account of harm that is both causal and contrastive. Finally, the paper contends that the contrastive account disarms the no harm argument and furthermore neutralizes a related argument that has been problematic for some previously proposed solutions to the non-identity problem.

Discrimination is a central epistemic capacity but typically, theories of discrimination only use discrimination as a vehicle for analyzing knowledge. This paper aims at developing a self-contained theory of discrimination. Internalist theories of discrimination fail since there is no compelling correlation between discriminatory capacities and experiences. Moreover, statistical reliabilist theories are also flawed. Only a modal theory of discrimination is promising. Versions of sensitivity and adherence that take particular alternatives into account provide necessary and sufficient conditions on discrimination. Safety in (...) contrast is not sufficient for discrimination as there are cases of safety that are clearly instances of discrimination failure. The developed account of discrimination between objects will be extended to discrimination between kinds and between types. (shrink)

Si le droit français « dit » la race, il lui nie une existence normative. A l’inverse, le droit de l’Union en fait un critère distinctif susceptible d’activer des dispositions juridiques liées au principe de non-discrimination. Ce changement de paradigme conduit le juge interne à modifier son approche traditionnelle des droits de l’Homme fondée sur le principe d’égalité. Les décisions du juge et du rapporteur public portent les traces d’aménagements dénominatifs lorsqu’il raisonne dans le cadre d’une approche plus relativiste, légitimant la différence de traitement.

This paper provides evidence for a contrastive account of explanation that is motivated by pragmatic theories that recognize the contribution that context makes to the interpretation of a prompt for explanation. This study replicates the primary findings of previous work in explanation-based category learning, extending that work by illustrating the critical role of the context in this type of learning. Participants interacted with items from two categories either by describing the items or explaining their category membership. We manipulated the feature (...) overlap between the categories and examined both the explanations generated and acquired knowledge of the categories. Explanations for membership in a given category were influenced by the unprompted contrast category, indicating an important role for contrastive processing in the generation of explanations. The influence of the contrast category was similarly seen in the transfer performance of the participants. (shrink)

The problem of mental causation is discussed by taking into account some recent developments in the philosophy of science. The problem is viewed from the perspective of the new interventionist theory of causation developed by Woodward. The import of the idea that causal claims involve contrastive classes in mental causation is also discussed. It is argued that mental causation is much less a problem than it has appeared to be.

Conscious visual perception can fail in many circumstances. However, little is known about the causes and processes leading to failures of visual awareness. In this study, we introduce a new signal detection measure termed subjective discriminability of invisibility that allows one to distinguish between subjective blindness due to reduction of sensory signals or to lack of attentional access to sensory signals. The SDI is computed based upon subjective confidence in reporting the absence of a target . Using this new measure, (...) we found that target misses were subjectively indistinguishable from physical absence when contrast reduction, backward masking and flash suppression were used, whereas confidence was appropriately modulated when dual task, attentional blink and spatial uncertainty methods were employed. These results show that failure of visual perception can be identified as either a result of perceptual or attentional blindness depending on the circumstances under which visual awareness was impaired.

This book re-evaluates New Left and Marxist texts from the 1980s, in order to explore problems facing the study of 'class' which have emerged within Australian and international theories. The author contrasts the popular ideas of Connell, Bourdieu and the 'Death of Class' thesis, with those of lesser known texts, concluding that no single definition can account for the various historical meanings of class. Instead, loosely following Castoriadis, the concept of class can best be understood as (...) creatively imagined and institutionalised. Paternoster proposes that class is best studied through historical phenomenology, which can be used to link political economy, cultural sociology and anthropological ethnographies. This approach allows the contributions of Marxist and New Left authors to be reintegrated with contemporary theories. Doing so highlights the significance of labour populism, while cautioning against the ahistorical applications of texts such as Boudieu's Distinction. Reimagining Class in Australia will be of interest to students and scholars across a range of disciplines, including sociology, history, political economy and anthropology. (shrink)

A discriminator logic is the 1 -assertional logic of a discriminator variety V having two constant terms 0 and 1 such that V ⊨ 0 1 iff every member of V is trivial. Examples of such logics abound in the literature. The main result of this research announcement asserts that a certain non-Fregean deductive system SBPC, which closely resembles the classical propositional calculus, is canonical for the class of discriminator logics in the sense that any discriminator logic S can (...) be presented as an axiomatic extension of SBPC by a set of extensional logical connectives taken from the language of S. The results outlined in this research announcement are extended to several generalisations of the class of discriminator logics in the main work. (shrink)
