推类是中国古代推理的主要模式。其结构通常由"言事"与"言道"两个部分组成。"言事"与"言道"的核心是"喻"。其理论根据是:所言事与道之间共同存在的"义"。找到事与道之间共同的"义",便可"扶义而动,推理而行"。由"事"理过渡到"道"理。推类的本质是论证。如果我们较好地掌握了"言事"与"言道"这二者的关系及"引譬"、"援类"的思维方式,对于正确理解中国古代思想家们的思想和丰富我们的思维方式具有重要意义。 相似文献

陈毅元帅的战争诗词是20世纪生动形象的革命战争史，又是壮美深沉的民族精英心灵史：在审美上既重风骨，又富意境；在形式上古近体并重，且创作颇丰。陈毅其人品性高洁，风骨凛然，其诗亦然，是20世纪传统诗词当之无愧的大家。 相似文献

后现代主要并非指的是一种时态,而是一种思想态度和意识,以及一种崭新的思考问题的方法。师生关系是一种特殊的社会关系,是教育的全部蕴念所在。根据后现代基本精神,本文力图重新审视教育过程中目前已被广泛认可的师生关系,从一种全面的、多元化、多层次的视角反思传统的师生关系,从而对师生关系问题形成新的有益的认识,即师生关系应从二元对立的主客关系转变为相互作用的共生关系,由单向的知识传授关系转变为双向的平等对话关系,从理性保障的师生关系转变为情感保障的师生关系。 相似文献

Pigeons responded in a successive-encounters procedure that consisted of a search period, a choice period, and a handling period. The search period was either a fixed-interval or a mixed-interval schedule presented on the center key of a three-key chamber. Upon completion of the search period, the center key was turned off and the two side keys were lit. A pigeon could either accept a delay followed by food (by pecking the right key) or reject this option and return to the search period (by pecking the left key). During the choice period, a red right key represented the long alternative (a long handling delay followed by food), and a green right key represented the short alternative (a short handling delay followed by food). The experiment consisted of a series of comparisons for which optimal diet theory predicted no changes in preference for the long alternative (because the overall rates of reinforcement were unchanged), whereas the hyperbolic-decay model predicted changes in preference (because the delays to the next possible reinforcer were varied). In all comparisons, the results supported the predictions of the hyperbolic-decay model, which states that the value of a reinforcer is inversely related to the delay between a choice response and reinforcer delivery. 相似文献

冯契认为,一切概念都有摹写现实与规范现实的双重作用,逻辑原则也体现着后验性与先验性的统一.在逻辑理论的证成问题上,"概念的双重作用"要求逻辑理论的建构必须坚持后验性与先验性的统一.有见于现代逻辑论证理论的普遍主义、先验主义倾向,非形式逻辑试图从后验性与先验性、普遍性与情境性的统一中去证成自身. 相似文献

对法律行为附加停止条件,是当事人自由意志的体现,与法律应否承认该法律行为从而赋予其强制力没有必然联系。停止条件的法律意义不在于影响法律行为效力的产生,而在于影响法律行为效力的内容。就是说停止条件不应该是法律行为的生效要件,而应该被看作是决定法律行为中特定之履行或者执行的因素。 相似文献

关洪涛 《河北职业技术学院学报》2007,7(1):41-43
悬赏广告是日常生活中常见的现象,同时也是一个在法理上很复杂的问题,其复杂性在于对其在法律性质上认识的不统一。就悬赏广告的特点、中外对于悬赏广告的三种不同的学说以及它们之间的差异、悬赏广告法律行为的效力争议等方面进行了阐述。 相似文献

服装设计并非洋洋洒洒的效果图或稀奇古怪的款式造型，而是服装造型与服装材料之间美的和谐、美的升华。任何优秀的服装都是设计与材料的完美结合。从某种意义上说，服装设计就是服装的造型风格的设计。服装造型的体现要有相应的辅料来支持。不同的辅料具有不同的表现性，辅料特征对服装的造型起到了至关重要的作用。可以说，服装的造型风格在很大程度上是由辅料的风格决定的。 相似文献

ABSTRACT: Lifelong learning is something which one does for oneself that no one else can do for one: it is a public and personal human activity, rather than private or individualistic. One of the features of the education system is the paucity of a language for learning as process and participative experience. Personalised learning requires a sense of the worthwhileness of 'being a learner'– a virtue in the 21st century. A sense of one's own worth as a person is essential to understanding one's identity as a learner. Research suggests the human capacity to learn can be understood as a form of consciousness which is characterised by particular values, attitudes and dispositions, with a lateral and a temporal connectivity. This 'consciousness' has several dimensions which are all related to becoming a person, with a learning identity. They also enable the learner to become aware of and appropriate what is of worth and map onto the sorts of core values that learning communities espouse. Awareness of self and of one's own worth as a person is a necessary condition for 'becoming a learner' and for identifying and engaging with 'what is of worth'. Furthermore, a sense of self as a learner is formed in relationship, and understood as one learns to tell one's own story, as a participant in the conversation of the learning community. Character is the way in which we refer to that quality of personhood in which there is rooted the capacity to change and learn over time. 相似文献

孟子的文论思想是先秦儒家文论的重要组成部分，特别是在文学欣赏与文学批评方面孟子的思想更是独树一帜，它涉及到创作主体、创作背景、语言表现，读者修养、阅读态度等一系列重大问题。在中国古代文学批评史上，除了刘勰、严羽等少数几位文学理论大师以外，还从来没有哪位哲人能像孟子这样把文学批评问题阐述得如此深刻，如此系统。具体来说，孟子的文论思想主要包括以下三个部分：(一)知人论世；(二)以意逆志：(三)养气知言。 相似文献

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return
on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates
and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio
(VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for
a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower
for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following
a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments,
and that few current theories of causal judgment explicitly predict this pattern of results. 相似文献
