Peirce: Underdetermination,Agnosticism, and Related Mistakes

There are two ways that we might respond to the underdetermination of theory by data. One response, which we can call the agnostic response, is to suspend judgment: “Where scientific standards cannot guide us, we should believe nothing”. Another response, which we can call the fideist response, is to believe whatever we would like to believe: “If science cannot speak to the question, then we may believe anything without science ever contradicting us”. C.S. Peirce recognized these options and suggested evading the dilemma. It is a Logical Maxim, he suggests, that there could be no genuine underdetermination. This is no longer a viable option in the wake of developments in modern physics, so we must face the dilemma head on. The agnostic and fideist responses to underdetermination represent fundamentally different epistemic viewpoints. Nevertheless, the choice between them is not an unresolvable struggle between incommensurable worldviews. There are legitimate considerations tugging in each direction. Given the balance of these considerations, there should be a modest presumption of agnosticism. This may conflict with Peirce's Logical Maxim, but it preserves all that we can preserve of the Peircean motivation.     

The Solipsism of Pornography: Speech Act Theory and the Anti-Porn Position

The present essay takes as its point of departure the resurgence of the anti-porn argument claiming that pornography is harmful. It focuses especially on philosopher Rae Langton’s attempt to use speech act theory to defend the anti-porn position of Catherine MacKinnon. Langton’s argument is critiqued for assuming that we can ascertain the function of pornography without considering the situations of its use. It hence runs counter to the particularizing intent of speech act theory as such, which emphasizes the need to study speech in context. Rather than dismiss the anti-porn position Langton defends as faulty, the essay suggests that it remains an incontrovertible facet of the pornographic situation, and as such should be dialectically engaged. In the second half of the essay, therefore, the reasoning that informs the antiporn position is shown to be incompatible with the recurrent claim that porn is the expression of a male desire to dominate women. Rather, a closer look at Langton’s defense of the anti-porn argument helps us see that pornography is the expression of cognitive possibilities unique to the historical conditions that have brought it forth, and as such is every bit as self-conflicting as is capitalism itself.     

A Structural Validation of an Inventory Based on the Abridged Five Factor Circumplex Model (AB5C)

Nineteen upper-middle class, pre-marital, college couples volunteered to participate in a study on interpersonal relationships. Couples received a modified Rorschach, thematic test, Marriage Value Inventory, a sex questionnaire, and an intensive depth interview. A Q sort of 100 personality items was used to assess the Ss. It was hypothesized that couples would show smaller discrepancies than randomized pairs, except for items relating to dominance, dependency, nurturance, exhibitionism, masculinity and femininity, where the reverse was predicted. Results confirmed the homogamy prediction, but only the dependency need was significant of the complementary predictions. Perception scores and expressive behavior are seen as potential adjuncts to questionnaires and inventories in predicting marital choice.     

Psychological Hardiness Predicts Success in a Norwegian Armed Forces Border Patrol Selection Course

The present study investigates the effects of psychological hardiness and successful completion of a rigorous 250‐km ski march over 9 days in Arctic winter conditions. This ski march is the final portion of a selection program for border rangers in the Norwegian Armed Forces. Study participants were N = 178 soldiers with a mean age of 19.9 years (range 18–23). Hierarchical regression results showed that successful completion of the ski march was predicted by total hardiness scores, after controlling for nutrition factors, physical fitness and sensation seeking. A second hierarchical regression found that the commitment facet of hardiness was the most significant predictor of ski march success, again controlling for nutrition, physical fitness and sensation seeking. Analyses of daily participant surveys showed that the high commitment group reported the highest levels of positive daily coping, and also evaluated their performance more positively. This group also showed increasingly positive self‐evaluations as the exercise went on. Together, these results indicate that hardiness commitment is a key factor influencing performance in a rigorous and stressful endurance task requiring sustained effort, perhaps by enhancing active coping skills and self‐efficacy beliefs.     

Color makes a difference: two-dimensional object naming in literate and illiterate subjects

Previous work has shown that illiterate subjects are better at naming two-dimensional representations of real objects when presented as colored photos as compared to black and white drawings. This raises the question if color or textural details selectively improve object recognition and naming in illiterate compared to literate subjects. In this study, we investigated whether the surface texture and/or color of objects is used to access stored object knowledge in illiterate subjects. A group of illiterate subjects and a matched literate control group were compared on an immediate object naming task with four conditions: color and black and white (i.e., grey-scaled) photos, as well as color and black and white (i.e., grey-scaled) drawings of common everyday objects. The results show that illiterate subjects perform significantly better when the stimuli are colored and this effect is independent of the photographic detail. In addition, there were significant differences between the literacy groups in the black and white condition for both drawings and photos. These results suggest that color object information contributes to object recognition. This effect was particularly prominent in the illiterate group.     

The meta-contrast technique: relationships with personality traits and cognitive abilities in a healthy male study sample

The relationship between defensive strategies as measured by the Meta-Contrast Technique (MCT) and self-reported trait anxiety, trait aggression and defensiveness, as measured by the Karolinska Scales of Personality (KSP), was investigated in 83 healthy men. Further aims of the study were to describe and document how a healthy and demographically well defined group of subjects responded to the MCT, and to investigate whether age, personality traits and cognitive abilities influenced the reports of picture recognition thresholds in the MCT. The results indicated no agreement between the conceptualization of anxiety as measured by the MCT and anxiety as measured by the KSP inventory. Nor was there any agreement between defensive strategies in the MCT and trait defensiveness as defined with the KSP. However, age, personality traits, and cognitive abilities all contributed to explain the variations in the threshold values of recognition of stimuli pictures, all of which are of central importance in the scoring of MCT protocols.     

Educational level, socioeconomic status and aphasia research: a comment on Connor et al. (2001)--effect of socioeconomic status on aphasia severity and recovery

Is there a relation between socioeconomic factors and aphasia severity and recovery? describe correlations between the educational level and socioeconomic status of aphasic subjects with aphasia severity and subsequent recovery. As stated in the introduction by, studies of the influence of educational level and literacy (or illiteracy) on aphasia severity have yielded conflicting results, while no significant link between socioeconomic status and aphasia severity and recovery has been established. In this brief note, we will comment on their findings and conclusions, beginning first with a brief review of literacy and aphasia research, and complexities encountered in these fields of investigation. This serves as a general background to our specific comments on, which will be focusing on methodological issues and the importance of taking normative values in consideration when subjects with different socio-cultural or socio-economic backgrounds are assessed.     

The place of Buddhism in Santayana's moral philosophy

Within the moral philosophy of the Spanish‐American philosopher George San‐tayana (1863–1952), reference to Buddhism becomes an essential feature in his formulation of the notion of post‐rational morality, which is that ‘phase’ of morality which involves an effort to subordinate all precepts to one that points to some single eventual good. Post‐rational morality is synonymous with the spiritual life, an essential feature of which is detachment; and this is why the Buddhists can be said to be the ‘true masters’ of the subject. Santayana's claim that Buddhism “suffers from a fundamental contradiction” can also be seen as an opportunity for us to deepen our own understanding of that philosophy.
