Rabbi and Magister: Overlapping intellectual models of the twelfth-century renaissance

Elka Klein’s writings have illuminated reciprocal and distinctive characteristics of the social and intellectual lives of Jewry in Iberia and by comparison Northern Europe during the High Middle Ages. This article honors her insights, by comparing the development of biblical hermeneutics at the Abbey of St. Victor in Paris and in the writings of Abraham ibn Ezra. Hugh of St. Victor’s introduction to the study of Scripture, Didascalicon, provides a program for the individual student to integrate all branches of human knowledge into the search for Divine Wisdom that may be found only in Scripture. The innovation in Hugh’s program is the emphasis on the “literal” or “historical” sense of Scripture as the solid basis for the development of theological study. Grammar and rhetoric were stepping stones that led the young theologians to higher levels of Divine Wisdom. The introduction to Abraham ibn Ezra’s commentary on the Pentateuch constitutes a parallel point of orientation for twelfth-century Jewish readers. A close reading of ibn Ezra’s prologue maps the hermeneutical approaches that different communities – Christian, rabbinic Jewish, and Karaite – utilized in their expositions of the Pentateuch. After critiquing each community, ibn Ezra offers his own approach that builds an overall framework for correct interpretation on the foundation of grammar and the rabbinic oral tradition. From this perspective, the article demonstrates that during this period Jews and Christians, both in Iberia and Northern Europe, focused on harmonizing reason and revelation. Both communities used grammar as the primary criterion for evaluating the accumulation of traditional sources. Both approaches intended to develop students, who were capable of understanding that “reason is the angel that mediates between God and humanity.”     

Gaining knowledge via other minds: Children's flexible trust in others as sources of information

In five experiments, we examined 3‐ to 6‐year‐olds’ understanding that they could gain knowledge indirectly from someone who had seen something they had not. Consistent with previous research, children judged that an informant, who had seen inside a box, knew its contents. Similarly, when an informant marked a picture to indicate her suggestion as to the content of the box, 3‐ to 4‐year‐olds trusted this more frequently when the informant had seen inside the box than when she had not. Going beyond previous research, 3‐ to 4‐year‐olds were also sensitive to informants’ relevant experience when they had to look over a barrier to see the marked picture, or ask for the barrier to be raised. Yet when children had to elicit the informant's suggestion, rather than just consult a suggestion already present, even 4‐ to 5‐year‐olds were no more likely to do so when the informant had seen the box's content than when she had not, and no more likely to trust the well‐informed suggestion than the uninformed one. We conclude that young children who can ask questions may not yet fully understand the process by which they can gain accurate information from someone who has the experience they lack.     

Links between physical fitness and cardiovascular reactivity and recovery to psychological stressors: A meta-analysis.

A meta-analysis of published studies with adult human participants was conducted to evaluate whether physical fitness attenuates cardiovascular reactivity and improves recovery from acute psychological stressors. Thirty-three studies met selection criteria; 18 were included in recovery analyses. Effect sizes and moderator influences were calculated by using meta-analysis software. A fixed effects model was fit initially; however, between-studies heterogeneity could not be explained even after inclusion of moderators. Therefore, to account for residual heterogeneity, a random effects model was estimated. Under this model, fit individuals showed significantly attenuated heart rate and systolic blood pressure reactivity and a trend toward attenuated diastolic blood pressure reactivity. Fit individuals also showed faster heart rate recovery, but there were no significant differences in systolic blood pressure or diastolic blood pressure recovery. No significant moderators emerged. Results have important implications for elucidating mechanisms underlying effects of fitness on cardiovascular disease and suggest that fitness may be an important confound in studies of stress reactivity.
