Philosophy and Cross-Cultural Conversation: Some Comments on the Project of Comparative Philosophy

This paper seeks to highlight the East-West asymmetry in philosophical exchanges. It draws attention to the absence of Eastern thought in the curriculum of philosophy in the West and suggests that cliches and stereotypes about cultures in general and thought-traditions in particular are perpetuated in this manner. The aim of the paper is to encourage 'cross-cultural conversation' among philosophers. A critical review of the project of 'comparative philosophy' is made to disclose the fact that despite the difficulties of such an endeavor, it is an attempt to bring thought-traditions together and is thereby useful for promoting intercultural understanding.     

Towards a Rough Mereology-Based Logic for Approximate Solution Synthesis. Part 1

We are concerned with formal models of reasoning under uncertainty. Many approaches to this problem are known in the literature e.g. Dempster-Shafer theory [29], [42], bayesian-based reasoning [21], [29], belief networks [29], many-valued logics and fuzzy logics [6], non-monotonic logics [29], neural network logics [14]. We propose rough mereology developed by the last two authors [22-25] as a foundation for approximate reasoning about complex objects. Our notion of a complex object includes, among others, proofs understood as schemes constructed in order to support within our knowledge assertions/hypotheses about reality described by our knowledge incompletely.     

Optimism and Revolt of the Oppressed: A Comparison of Two Polish Jewish Ghettos of World War II

One World War II Jewish ghetto that revolted, the Warsaw Ghetto, is compared to one that did not, the Lodz Ghetto, in order to examine the causes of violent resistance. This structured focused comparative method (George, 1979) illuminates problems with previous explanations for revolt and nonrevolt in Jewish ghettos and suggest psychological variables that might have led to or precluded organized violence. Specifically, it appears that these two ghettos differed in their perceptions about their future. The residents of the Warsaw Ghetto believed they had no hope of survival while residents of the Lodz Ghetto remained optimistic. These differing perceptions seem to have led to the different outcomes. Possible causes of these percetpions are also discussed.     

Further remarks on the role of cognition in the comparative analysis of behavior

Recent interest in comparative psychology has stimulated much research and debate concerning cognitive processes in animal behavior. The present paper relates to this general area by treating particular issues in the analysis of comparative cognition: specifically, how cognition is inferred from animal behavior; whether the postulation of intervening cognitive processes furthers our understanding of behavior; and how rival approaches help advance the science of behavior.     

Comparative Religious Ethics and the Politics of Christian Identity

I present a brief historical narrative of the legacy of Christian ethics in comparative religious ethics (CRE) that attempts to make sense of the tensions within the field from the perspective of the politics of identity with reference to its changing content and practices—its internal history—and what might be called the background conditions—its external history—that shaped not only the content and methods of CRE but also its self‐understanding. Given the politics of Christian identity and the historical development of religious ethics within the American academy, I recommend that scholars of CRE adopt a more confessional mode of inquiry that makes explicit their ultimate commitments.     

“‘Othering’ with Grace and Courage”

This essay considers the complexity and dynamic of seeking to balance an openness to the religious “other” and their beliefs with the honest acknowledgement of real and often deep incommensurability between one's own and the other's deepest convictions. This kind of hospitable and mutually edifying encounter is possible by putting into practice the method of comparative theology which, while urging the faithful in every tradition to establish their own religious identity, also facilitates learning from the other and makes room for sharing one's own testimony. Not only theological and confessional but also autobiographical and life narratives matter in this process.     

Attentional sets influence perceptual load effects,but not dilution effects

Perceptual load theory [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–468.; Lavie, N., & Tsal, Y. (1994) Perceptual load as a major determinant of the locus of selection in visual attention. Perception & Psychophysics, 56, 183–197.] proposes that interference from distractors can only be avoided in situations of high perceptual load. This theory has been supported by blocked design manipulations separating low load (when the target appears alone) and high load (when the target is embedded among neutral letters). Tsal and Benoni [(2010a). Diluting the burden of load: Perceptual load effects are simply dilution effects. Journal of Experimental Psychology: Human Perception and Performance, 36, 1645–1656.; Benoni, H., & Tsal, Y. (2010). Where have we gone wrong? Perceptual load does not affect selective attention. Vision Research, 50, 1292–1298.] have recently shown that these manipulations confound perceptual load with “dilution” (the mere presence of additional heterogeneous items in high-load situations). Theeuwes, Kramer, and Belopolsky [(2004). Attentional set interacts with perceptual load in visual search. Psychonomic Bulletin & Review, 11, 697–702.] independently questioned load theory by suggesting that attentional sets might also affect distractor interference. When high load and low load were intermixed, and participants could not prepare for the presentation that followed, both the low-load and high-load trials showed distractor interference. This result may also challenge the dilution account, which proposes a stimulus-driven mechanism. In the current study, we presented subjects with both fixed and mixed blocks, including a mix of dilution trials with low-load trials and with high-load trials. We thus separated the effect of dilution from load and tested the influence of attentional sets on each component. The results revealed that whereas perceptual load effects are influenced by attentional sets, the dilution component is not. This strengthens the notion that dilution is a stimulus-driven mechanism, which enables effective selectivity.     

Partial Monotonic Protothetics

This paper has four parts. In the first part, I present Leniewski's protothetics and the complete system provided for that logic by Henkin. The second part presents a generalized notion of partial functions in propositional type theory. In the third part, these partial functions are used to define partial interpretations for protothetics. Finally, I present in the fourth part a complete system for partial protothetics. Completeness is proved by Henkin's method [4] using saturated sets instead of maximally saturated sets. This technique provides a canonical representation of a partial semantic space and it is suggested that this space can be interpreted as an epistemic state of a non-omniscient agent.     

Comparing Latent Structures of the Grade of Membership,Rasch, and Latent Class Models

This paper focuses on model interpretation issues and employs a geometric approach to compare the potential value of using the Grade of Membership (GoM) model in representing population heterogeneity. We consider population heterogeneity manifolds generated by letting subject specific parameters vary over their natural range, while keeping other population parameters fixed, in the marginal space (based on marginal probabilities) and in the full parameter space (based on cell probabilities). The case of a 2 × 2 contingency table is discussed in detail, and a generalization to 2^J tables with J ≥ 3 is sketched. Our approach highlights the main distinction between the GoM model and the probabilistic mixture of classes by demonstrating geometrically the difference between the concepts of partial and probabilistic memberships. By using the geometric approach we show that, in special cases, the GoM model can be thought of as being similar to an item response theory (IRT) model in representing population heterogeneity. Finally, we show that the GoM item parameters can provide quantities analogous to more general logistic IRT item parameters. As a latent structure model, the GoM model might be considered a useful alternative for a data analysis when both classes of extreme responses, and additional heterogeneity that cannot be captured by those latent classes, are expected in the population.
