The discussion is a response to Dews on the question of how Schelling's Freiheitsschrift should be interpreted. It falls into two halves, the first defending my interpretation, and the second expanding on the case that Dews makes for the unavoidability of metaphysics in the theory of human freedom, with which I am in full agreement. The main criticism that Dews makes of my reading is that the argument I attribute to Schelling concerning the metaphysical significance of evil rests on Kantian assumptions regarding the existence of pure practical reason, which Schelling rejects. I argue that, though certainly matters are more complicated than my earlier discussion made them seem, Schelling remains sufficiently close to Kant for the argument I attribute to avoid inconsistency. In the second half I raise what I claim to be a neglected but important question: Why is the legacy of classical German philosophy not regarded as significant for contemporary discussion of human freedom? My answer in brief is that the concept of freedom has undergone a profound contraction. In this context I also try to define more precisely what is distinctive of Schelling's view of human freedom. 相似文献

This article addresses the still popular but incorrect idea that monofractal (sometimes called “fractal” for short) structure might be a definitive signature of nonlinearity and, as a corollary, that monofractal analyses are nonlinear analyses. That this point (i.e., “fractal = nonlinear”) is incorrect remains novel to many readers. We suspect that unfamiliarity with autocorrelation has helped eclipse the linearity of fractal structure from more popular appreciation. In this article, in order to explain the linear nature of monofractality and its difference from multifractality, we present an introduction to the autocorrelation function and review short-lag memory, nonstationary motions, and the intermediary set of fractionally integrated processes that conventional fractal analyses quantify. Understanding from our own experiences how surprising the linearity of fractals is to accept, we attempt to make our points clear with as much graphic depiction as math. We hope to share our own experiences in struggling with this potentially strange-sounding idea that, really, monofractals are linear while at the same time contrasting them to multifractals that can indicate nonlinearity. 相似文献

Werther Effect research has almost solely focused on the behavioral level of media effects. Clinically relevant predispositions like depression as well as the moderating role of media effects on a perceptional level have been omitted so far. To bridge this gap, we reanalyzed the data of an experiment conducted by Rustad, Small, Jobes, Safer, and Peterson: volunteer students' ratings for their self-risk of depression and suicide as well as their perceptions of others' suicide risk were investigated. While a Werther Effect could not be observed, there is a general overestimation of media influences on others--presumed Werther Effects--that are moderated by the personal degree of depression. 相似文献

Entorhinal neurons receive extensive intracortical projections, and form the primary input to the hippocampus via the perforant pathway. The glutamatergic cells of origin for the perforant pathway are distinguished by their expression of reelin, a glycoprotein involved in learning and synaptic plasticity. The functional significance of reelin signaling within the entorhinal cortex, however, remains unexplored. To determine whether interrupting entorhinal reelin signaling might have consequences for learning and memory, we administered recombinant receptor-associated protein (RAP) into the lateral entorhinal cortex (LEC) of young Long-Evans rats. RAP prevents reelin from binding to its receptors, and we verified the knockdown of reelin signaling by quantifying the phosphorylation state of reelin’s intracellular signaling target, disabled-1 (DAB1). Effective knockdown of reelin signaling was associated with impaired performance in the hippocampus-dependent version of the water maze. Moreover, inhibition of reelin signaling induced a localized loss of synaptic marker expression in the LEC. These observations support a role for entorhinal reelin signaling in spatial learning, and suggest that an intact reelin signaling pathway is essential for synaptic integrity in the adult entorhinal cortex. 相似文献

I argue from a hermeneutic point of view that formal elements of poetry can only be identified because poetry is based on
both the phenomenon and the conception of poetry, both of which precede the attempt to identify formal elements as the defining
moment of poetry. Furthermore, I argue with Gadamer that poetry is based on a rupture with and an epoche of our non-poetic use of language in such a way that it liberates “fixed” universal aspects of everyday language, and that
through establishing itself in a new, self-referential and monologue unity, it individualizes speech. From the hermeneutic position, poetry is a form of speaking rather than a “fixed” object. As such, I will try to make sense
of what Paul Celan said in his famous “Meridian” speech: namely, that the poem is “actualized language, set free under the
sign of a radical individuation, which at the same time stays mindful of the limits drawn by language, the possibilities opened
by language.” 相似文献

Knock-out studies in mice suggest a role of the CHRNA4 gene in anxiety. In the present study we extend this finding to humans by means of a genetic association study. In a sample of N = 574 healthy White participants, the CHRNA4 rs1044396 polymorphism is related to the common variance of several conceptualizations of negative emotionality. Compared to carriers of at least one T-allele, carriers of the homozygous C/C genotype described themselves as more anxious and emotionally unstable on various psychometric personality questionnaires. The scope of the genetic effect is remarkable because other prominent genetic markers for anxiety show specificity for the diagnostic tool used. The present study is the first study that demonstrates the relevance of the CHRNA4 gene for negative emotionality in humans and sets a starting point for further investigations that could inform on the treatment of various affective psychiatric disorders. 相似文献

The mechanisms for the substantial variation in the durations of visual fixations in scene perception are not yet well understood. During free viewing of paintings, gaze-contingent irrelevant distractors (Exp. 1) and non-gaze-related time-locked display changes (Exp. 2) were presented. We demonstrated that any visual change-its onset and offset-prolongs the ongoing fixation (i.e., delays the following saccade), strongly suggesting that fixation durations are under the direct control of the stimulus information. The strongest influence of distraction was observed for fixations preceded by saccades within the parafoveal range (<5° of visual angle). We assume that these fixations contribute to the focal in contrast to the ambient mode of attention (Pannasch & Velichkovsky, Visual Cognition, 17, 1109-1131, 2009; Velichkovsky, Memory, 10, 405-419, 2002). Recent findings about two distinct "subpopulations of fixations," one under the direct and another under the indirect control of stimulation (e.g., Henderson & Smith, Visual Cognition, 17, 1055-1082, 2009), are reconsidered in view of these results. 相似文献

Recent structural and functional imaging studies have provided evidence for continued development of brain regions involved in social cognition during adolescence. In this paper, we review this rapidly expanding area of neuroscience and describe models of neurocognitive development that have emerged recently. One implication of these models is that neural development underlies commonly observed adolescent phenomena such as susceptibility to peer influence and sensitivity to peer rejection. Experimental behavioural evidence of rejection sensitivity in adolescence is currently sparse. Here, we describe a study that directly compared the affective consequences of an experimental ostracism manipulation (Cyberball) in female adolescents and adults. The ostracism condition led to significantly greater affective consequences in the adolescents compared with adults. This suggests that the ability to regulate distress resulting from ostracism continues to develop between adolescence and adulthood. The results are discussed in the context of models of neurocognitive development. 相似文献
