辩证逻辑

黑格尔对形式逻辑和辩证逻辑的看法辩证逻辑是德国哲学家黑格尔在十九世纪初引入的哲学术语。这个术语是他用来称呼自己关于一切“自然和精神事物”发展的规律的唯心主义学说的,又同被他作了歪曲解释的形式逻辑直接地对立起来。他正确地指出了他那个时代哲学理论的弊病之一,就是思维的规律和形式被形而上学地看作为某种一成不变的东西。其实,受工业生产的进步所制约的自然科学的发展已经表明,形而上学和它的     

评Б.М.凱德洛夫的《自然科学的对象和相互联系》

直到最近时期,在某些地方还感觉到(甚至现在还是这样)在自然科学家们同哲学家们的相互关系上有显明的“冷淡”。这里,事情不在于缺乏相互尊重,而是某些自然科学家有时不太感觉得到哲学研究工作对于自己经常的理论工作和实验工作有什么直接的必要性。显然,哲学研究同自然科学研究的相互关联是很不够的,而这种相     

罗任等教授谈苏联40年来哲学的发展

列宁格勒大学哲学系于1957年11月25—29日举行了学术会议,纪念伟大的十月社会主义革命四十周年。符·普·罗任教授作了“四十年来马克思列宁主义哲学的发展”的报告。报告分为三个部份。在第一部份“社会主义社会理论的创立和发展”中,报告人着重指出,在伟大的十月社会主义革命胜利之后,历史唯物主义问题被提到了首要地位,因为在我国建设社会主义当时已经成为我国亿万劳动人民的实际的、迫切的和创造性的事业。以伟大领袖列宁为首的、在战斗中经过考验和

Challenging racism, sexism, and social injustice: support for urban adolescents' critical consciousness development

This mixed-model study examined the relationship between urban adolescents' perceived support for challenging racism, sexism, and social injustice from peers, family, and community members and their critical consciousness development. These relationships were examined by relating participants' qualitative perceptions of support for challenging racism, sexism, and social injustice to quantitative data obtained from Likert-type measures of the reflection and action components of critical consciousness. Perceived support for challenging racism, sexism, and social injustice had a significant impact upon the reflection component of critical consciousness; the significance criterion was supported by effect size estimates. Support for challenging racism, sexism, and social injustice was not significantly related to the action component of critical consciousness. Participants perceived the most support for challenging racism, moderate support for challenging social injustice, and the least support for challenging sexism. Additionally, female participants perceived more support for challenging sexism than male participants. These results suggest that the informal interactions of urban adolescents play a role in shaping their critical consciousness, and hold implications for psychosocial interventions and research with marginalized populations.     

Impaired memory consolidation in rats produced with beta-adrenergic blockade

Despite abundant evidence that systemic administration of adrenergic drugs and hormones can produce retrograde memory enhancement, the literature contains no clear demonstration that postlearning systemic administration of adrenergic antagonists produces retrograde amnesia. Here we demonstrate retrograde amnesia for a stressful learning task (a spatial water maze) with systemic administration of the beta-adrenergic antagonist propranolol (5 mg/kg). The amnesic effect of the drug depended on the degree of learning in the subjects: Propranolol caused a robust retrograde amnesia in "good learners," but did not significantly affect memory in "poor learners." The findings provide critical additional support for the hypothesis that postlearning adrenergic activation modulates memory consolidation processes after emotionally stressful events and help explain previous failures to detect memory impairment after systemic administration of adrenergic blocking drugs.     

Suicidal Adolescents' Social Support from Family and Peers: Gender-Specific Associations with Psychopathology

Perceptions of social support from family, non-family adults, and peers were examined in relation to the psychopathology reported by 220 suicidal adolescents (152 females) during a psychiatric hospitalization. Results of regression analyses showed that, among females, family support was negatively related to hopelessness, depressive symptoms, and suicidal ideation. Among males, peer support was positively associated with depressive symptoms and suicidal ideation. Across gender, more peer support was associated with more externalizing behavior problems; whereas, family support was negatively related to these problems and to alcohol/substance abuse. Paralleling normative findings, age was positively associated with peer support, and females perceived more peer support than did males. Findings extend previous research on social support to suicidal adolescents, and broaden the literature by examining extrafamilial support and a broader range of relevant psychopathology. That is, perceived social support relates to psychiatric impairment differentially by gender, and normative, age-related variations in perceptions of social support are detected even among highly impaired adolescents. Clinical implications and directions for future research are discussed.     

The role of cognitive factors in the pathogenesis of obsessive-compulsive symptoms: a prospective study

Cognitive models of obsessive-compulsive disorder (OCD) posit that specific kinds of dysfunctional beliefs (e.g., pertaining to responsibility and the significance of intrusive thoughts) underlie the development of this disorder. The present study was designed to prospectively evaluate whether dysfunctional beliefs thought to underlie OCD act as a specific vulnerability factor in the pathogenesis of obsessive-compulsive symptomatology. Eighty-five individuals were prospectively followed over a period of time thought to be associated with an increased onset of OCD symptoms -- childbirth and the postpartum. The majority of these new mothers and fathers experienced intrusive infant-related thoughts and performed neutralizing behaviors similar to, but less severe than, those observed in OCD. Scores on a measure of dysfunctional beliefs thought to underlie OCD predicted the development of obsessive-compulsive symptoms after controlling for pre-existing OCD symptoms, anxiety, and depression. Dysfunctional beliefs also predicted the severity of checking, washing, and obsessional OCD symptom dimensions, but not neutralizing, ordering, or hoarding symptom dimensions. These data provide evidence for specific dysfunctional beliefs as risk factors in the development of some types of OCD symptoms.     

Object onset and parvocellular guidance of attentional allocation

The parvocellular visual pathway in the primate brain is known to be involved with the processing of color. However, a subject of debate is whether an abrupt change in color, conveyed via this pathway, is capable of automatically attracting attention. It has been shown that the appearance of new objects defined solely by color is indeed capable of modulating attention. However, given evidence suggesting that the visual system is particularly sensitive to new onsets, it is unclear to what extent such results reflect effects of color change per se, rather than effects of object onset. We assessed attentional capture by color change that occurred as a result of either new objects appearing or already-present "old" objects changing color. Results showed that although new object onsets accrued attention, changing the color of old objects did not. We conclude that abrupt color change per se is not sufficient to capture attention.     

论俄国的内在状况

俄罗斯民族是一个不关心政治的民族,她没有对自治的渴求,没有对政治权利的渴望.俄国要实现她的使命,必须遵循自己的理念和要求,而不是那些与她格格不入的理论.俄国有两个方面:国家和百姓.她们之间的理想状态是:人民不干预政府的或行政的事务,给政府无限的统治自由,让政府有行动的权利和相应的法律的权力;而国家并不干预人民的生活方式.给人民以政府保护下的充分的社会和精神生活自由,让人民有发表意见的权利和相应的言论自由.沙皇和百姓之间的正确关系一旦被恢复了,俄罗斯从苦难中就会被解救出来.
