The purpose of this study is to discuss the dynamic interdependence of knowledge and economic growth. We show that the traditional economics, which treats knowledge as parameters and is mainly developed within linearized, stable and static frameworks can hardly explain the modern economic complexity. We argue that it is necessary to treat creativity, learning and knowledge utilization as endogenous dynamic processes of social and economic evolution. To handle with the complicated dynamic interdependence of wealth and knowledge accumulation, we need to apply genuine nonlinear dynamic theory. In particular, we discuss possible benefits of government's intervention in education and science to the society when the social and economic evolution is characterized of nonlinearity, instability and multi‐equilibria. 相似文献

The postmodern world seems to have conclusively lost faith in the heady promises of human emancipation through rational understanding that have pervaded the Western world since the time of the Enlightenment. As the end of the millennium approaches and the evidence of man‐made environmental degradation accumulates nihilism and malaise color the future. This article argues that a clear understanding of both evolutionary forces and human consciousness permits to formulate a guardedly optimistic alternative view. It is advanced that the very sense of despair current circumstances have created may trigger a move toward a new form of psycho‐functional adaptation, simultaneously constituting a first instance of “conscious evolution” and fulfilling the progressive promise intrinsic in the full use of our rational faculties. 相似文献

The “choreography of everyday life refers to the existence of rules of daily life, correspondingly to those of dances: the rules impose order upon individual behavior beyond the level of pure improvisation. The fact that acts of everyday life repeat themselves supports the idea that there exist some mechanisms generating order to daily practices. The replicative model of evolution is a candidate to explain this process of routinization. At the beginning of a replicative cycle behavioral patterns might change radically. In the course of time integrative and competitive selective forces start working. Finally some established rules, choreography, determining daily practices will emerge. In this mature phase identical replication takes place. 相似文献

Using free energy rate density (Φm) I differentiate two evolutionary strategies common to cosmic, biological, and cultural systems: the horizontal when energy increases proportional to mass, with no increase in complexity; and the vertical when it increases disproportionately to the mass and complexity increases. The vertical process is a continuing increase in complexity such that the system becomes vulnerable to collapse when energy sources fail. This is illustrated by a comparison of four Mayan Indian groups in Guatemala. 相似文献

We carried out an investigation with primary-school children on the relationship between both use and comprehension of emotional-state language and emotion understanding. Participants were 100 students between 7 and 10 years old (mean age=8 years and 10 months; SD=15.3 months), equally divided by gender. They completed four tests evaluating their language ability, use of emotional-state language, comprehension of emotional-state language and emotion understanding (EU) respectively. Significant correlations were found between both use and comprehension of emotional-state talk and children's EU. In addition, regression analyses showed that comprehension of emotional-state language, rather than its use, plays a significant role in explaining children's emotion understanding. 相似文献

This paper argues for culture as a significant determinant of the modern human genome. As progress in the fields of genetics and evolutionary biology have gained greater insights into evolutionary process, aspects of classical proposals explaining how phenotypic responses to environmental experience could make their way into the genotype have returned in new guises. Recent proposals recognize environmental context as a key source of genetic variation by directly altering selection pressures to mask and unmask adaptive value of expressed traits, by reorganizing the combination and expression of genes during ontogeny to provide novel variants for selection, and by influencing developmental trajectories through epigenetic systems acutely sensitive to ontogenetic contexts. The emergence of a robust human socio-cultural niche, shielding humans from more proximate evolutionary pressures that marked our ancestral evolution, has arguably provided the strongest directive force on modern human evolution. Language is discussed as an exemplar of a cultural niche with a powerful self-organizing dynamic and the potential to dramatically alter the human genome. 相似文献

David Hume argued that ought cannot be derived from is. That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume''s words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith. 相似文献

Because the definition of behavior changes as our understanding of behavior changes, giving a final definition is impossible. One can, however, rule out some possibilities and propose some others based on what we currently know. Behavior is not simply movement, but must be defined by its function. Also, our understanding of behavior must agree with evolutionary theory. I suggest 4 basic principles: (a) only whole organisms behave; (b) behavior is purposive; (c) behavior takes time; and (d) behavior is choice. Saying that parts of an organism behave is nonsense, and, moreover, evolutionary theory explains the existence of organisms mainly through their adaptive behavior. Behavior is purposive in that behavior is shaped by its consequences, through an organism''s lifetime or through interactions with the environment across many generations of natural selection. Behavior takes time in that behavior is interaction with the environment that cannot take place at a moment. Moreover, at a moment in time, one cannot definitely identify the function of behavior. Identification of an activity requires a span of time. Behavior is choice in the sense that a suitable span of time always includes time spent in more than 1 activity. Activities include parts that are themselves activities on a smaller time scale and compete for time. Thus, behavior constitutes time allocation. An accounting problem arises whenever any behavior is attributed to multiple consequences. In the molar multiscale view, this raises the question of whether 2 activities can occur at the same time. The question remains open. 相似文献

In this article the author holds that progress in philosophy is a vague concept. Its criteria are not universally acknowledged. All that is clear is that philosophy does not develop in a linear way. Philosophy is polydiscoursive. As for the past fifty years, the author believes three important things happened in philosophy. (1) It has been shown that consciousness exists not within one individual but spreads within a community of people; (2) philosophy has discovered autism, a result that helps us to understand a human being as neither a biological nor a social individual but a third thing—a dreaming being who is not only asocial but also tongueless, where speech and consciousness are separated; and (3) contemporary philosophy has learned to distinguish between sign and symbol. And it has been realized that the human mind is neither an instinct nor a computer but an objectified suffering, a transformed emotion. 相似文献

Throughout his career, a central feature of Roy Schafer's theorizing has been to highlight the role of activity and personal agency in every facet of human experience. This theme has remained at the forefront of Schafer's work, despite being embedded within different frames of reference. In this paper, the author highlights Schafer's focus on activity, notes some clinical problems to which it can give rise, and suggests the way that Schafer has attempted to deal with these difficulties. 相似文献
