Ontological difference,anthropological difference,and equal liberty

In this lecture, the author seeks to articulate in a systematic manner, although still tentative, the three ideas about which he has been developing his personal philosophy in the last period: “Ontological difference”, which after Heidegger and Derrida needs to become redefined in terms of a quasi‐transcendental problematic of alterity; “anthropological difference”, which covers the wholerange of oppositions which at the same time are inseparable from a representation of the “human” and impossible to define as invariable binaries; “equal liberty”, the combination of heterogeneous values which, since Ancient democracies and Modern republican insurrections, has installed the tension of emancipation at the heart of the political institution.     

Dissimilarity and attraction: when difference makes a difference.

Students in 93 university classes described themselves and their instructors on personality tests measuring traits relevant (ascendancy and personal relations) and irrelevant (sociability and cautiousness) to teaching skill. Dissimilarity (instructor being higher than student) on relevant trait dimensions was hypothesized to be instrumental for student satisfaction with an instructor's role performance. When students were classified as similar or dissimilar to their instructors on the personality dimensions, those most attracted to their instructors were those dissimilar on relevant (but not irrelevant) traits. The dissimilarity finding was not an artifact of differences in skill of instructor nor of differences in students' perceptions of their instructors' traits. A three-dimensional system was devised to specify when similarity and dissimilarity should promote attraction.     

Comparative visual search: a difference that makes a difference

In this article we present a new experimental paradigm: comparative visual search. Each half of a display contains simple geometrical objects of three different colors and forms. The two display halves are identical except for one object mismatched in either color or form. The subject's task is to find this mismatch. We illustrate the potential of this paradigm for investigating the underlying complex processes of perception and cognition by means of an eye-tracking study. Three possible search strategies are outlined, discussed, and reexamined on the basis of experimental results. Each strategy is characterized by the way it partitions the field of objects into "chunks." These strategies are: (i) Stimulus-wise scanning with minimization of total scan path length (a "traveling salesman" strategy), (ii) scanning of the objects in fixed-size areas (a "searchlight" strategy), and (iii) scanning of object sets based on variably sized clusters defined by object density and heterogeneity (a "clustering" strategy). To elucidate the processes underlying comparative visual search, we introduce besides object density a new entropy-based measure for object heterogeneity. The effects of local density and entropy on several basic and derived eye-movement variables clearly rule out the traveling salesman strategy, but are most compatible with the clustering strategy.     

Envy and difference

This paper explores five examples of envy, examining the similarities and differences between the clinical situations. The theory relating to envy is extensively reviewed and a critique of the Kleinian position is offered, suggesting that the aversion to separation and difference is not only prior to, but also has explanatory precedence over, the functioning of envy. Kleinian examples are explored in this light. The experience of separateness and difference is understood to lead to a number of outcomes: envy, admiration, competitiveness, a sense of low self-esteem and inadequacy, or a fear of being envied. It is argued that the individual's particular personality organization and their associated relational pattern will determine their experience of envy. Examples of schizoid, borderline, narcissistic and hysteric functioning in relation to envy are examined in some depth. The link between these phenomena and the death instinct is touched on.     

Sexuate difference, ontological difference: Between Irigaray and Heidegger

Animating Luce Irigaray’s oeuvre are two indissociable projects: the disruption of Western metaphysics and the thinking of sexual difference. The intersection of these two projects implies that any attempt to think through the meaning and significance of Irigaray’s notoriously fraught invocation of sexual difference must take seriously the way in which this invocation is itself always already inflected by her disruptive gesture. In this paper, I will attempt to elucidate one moment of this intersection by focusing on her critical engagement with Heidegger. In L’oubli de l’air, Irigaray criticizes Heidegger’s interpretation of the principle of identity as instantiating the same neglect of sexual difference that has been inscribed throughout the history of Western metaphysics. Moreover, Irigaray identifies the vestigial traces of this metaphysical legacy in Heidegger’s commitments to phenomenology. My claim, however, is that if we turn to Derrida’s second Geschlecht essay in order to mediate between Irigaray and Heidegger, the coimplicative nature of their projects comes into focus: on one hand, Derrida identifies within Heidegger’s work an incipient articulation of the very notion of sexuate difference that, on Irigaray’s reading, Heidegger’s work requires but nonetheless elides; on the other hand, Derrida’s rereading of Heidegger’s phenomenological commitments corroborates the philosophical significance of Irigaray’s intervention by recontextualizing the parameters that delimit her invocation of sexuate difference.     

The difference between t and z and the difference it makes

Tests of the null hypothesis for comparisons involving sample means use the t test when the conditions of the z test cannot be met. The 2 tests have different rationales and can lead to different conclusions regarding significance. In the present study, the authors compared the properties of t and z in simulation runs. The differences in the results are a result of fluctuations in the t test sample variances that do not exist in the z test, and those differences lead to differences in designating the significance of comparisons.     

The genetic difference principle

In the newly emerging debates about genetics and justice three distinct principles have begun to emerge concerning what the distributive aim of genetic interventions should be. These principles are: genetic equality, a genetic decent minimum, and the genetic difference principle. In this paper, I examine the rationale of each of these principles and argue that genetic equality and a genetic decent minimum are ill-equipped to tackle what I call the currency problem and the problem of weight. The genetic difference principle is the most promising of the three principles and I develop this principle so that it takes seriously the concerns of just health care and distributive justice in general. Given the strains on public funds for other important social programmes, the costs of pursuing genetic interventions and the nature of genetic interventions, I conclude that a more lax interpretation of the genetic difference principle is appropriate. This interpretation stipulates that genetic inequalities should be arranged so that they are to the greatest reasonable benefit of the least advantaged. Such a proposal is consistent with prioritarianism and provides some practical guidance for non-ideal societies--that is, societies that do not have the endless amount of resources needed to satisfy every requirement of justice.     

Contextual effects in difference judgments

Manipulating stimulus spacing, stimulus frequency, or stimulus range usually affects intensity judgments. In six experiments, I investigated the locus of analogues of these contextual effects in a “difference” estimation task. When all stimuli elicited the same taste quality, stimulus distribution affected the scale values only when water was included in the stimulus set (Experiments 1–3). When the subjective ranges of two taste qualities were manipulated, different scale values were obtained for the separate qualities in the two conditions (Experiment 4). Manipulation of the expected response distribution did not affect the scale values or the responses (Experiments 5–6). It is concluded that shifts in stimulus distributions or stimulus ranges result in shifts in subjective scale values. The contextual effects can be interpreted as relative shifts of a number of gustatory continua, with water lying on a separate continuum. Proposed is a model for context-dependent judgments, consisting of four stages: stimulus classification, stimulus placement, continuum placement, and continuum projection.     

What difference reveals about similarity

Detecting that two images are different is faster for highly dissimilar images than for highly similar images. Paradoxically, we showed that the reverse occurs when people are asked to describe how two images differ--that is, to state a difference between two images. Following structure-mapping theory, we propose that this disassociation arises from the multistage nature of the comparison process. Detecting that two images are different can be done in the initial (local-matching) stage, but only for pairs with low overlap; thus, "different" responses are faster for low-similarity than for high-similarity pairs. In contrast, identifying a specific difference generally requires a full structural alignment of the two images, and this alignment process is faster for high-similarity pairs. We described four experiments that demonstrate this dissociation and show that the results can be simulated using the Structure-Mapping Engine. These results pose a significant challenge for nonstructural accounts of similarity comparison and suggest that structural alignment processes play a significant role in visual comparison.     

On the difference it makes

Man's belief in God is often contrasted with man's disbelief, Atheism; but the nature of human belief is contrastable with the nature of the belief of demons. A point of contrast lies in the consequences of the different sort of reasons men and demons must be understood to have. One consequence has to do with the vision of the world, seeing the world as God's creation, which men are expected to achieve and demons are not. The logic of the ‘seeing as’ formula is explored and found wanting even though it seems inescapable in connection with human belief. In the end human belief appears more peculiar than demonic.
