Abstract. Working in Britain and in Poland, the authors independently arrived at an interpretation of spirituality as a natural phenomenon. From the point of view of the British author, spirituality is based on a biological predisposition that has been selected for in the process of evolution because it has survival value. In several important ways this approach is in harmony with the psychological perspective of the Polish author that sees spirituality as a socioculturally structured and determined attempt to cope with the existential human situation. Thus interpreted, spirituality is a human universal appearing in many secular as well as religious forms, although its most typical manifestations have been in religious experience. In this essay we discuss research data in support of this theoretical point of view and highlight some of the issues in bringing the two theoretical perspectives together.  相似文献

SUMMARY

The role of aging and culture in the attainment of wisdom is examined m this chapter. The concept of wisdom m industrialised societies is briefly explored. It is argued that both biology and culture can be positive or negative factors m the capacity of a person to be “wise.” It is concluded that, for many, the negative impact of biological factors of aging are overwhelming, but, for a few, aging enriches their insight.  相似文献

The momentum of advances in biology is evident in the history of patents on life forms. As we proceed forward with greater understanding and technological control of developmental biology there will be many new and challenging dilemmas related to patenting of human parts and partial trajectories of human development. These dilemmas are already evident in the current conflict over the moral status of the early human embryo. In this essay, recent evidence from embryological studies is considered and the unbroken continuity of organismal development initiated at fertilization is asserted as clear and reasonable grounds for moral standing. Within this frame of analysis, it is proposed that through a technique of Altered Nuclear Transfer, non-organismal entities might be created from which embryonic stem cells could be morally procured. Criteria for patenting of such non-organismal entities are considered. An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights and Patents,” held in Warsaw, Poland on 23–24 April, 2004.  相似文献

Abstract. The morality of human beings, defined here as our ability to determine whether our actions are right or wrong, depends not just on following rules but also on understanding the impact of our actions on another person. How we understand the impact of our actions on another person depends on our state of consciousness, which is mediated by our brain and nervous system. We describe how we understand our morality to flow naturally from the biological state we are living in and how we see our biology and our morality as mutually interactive. A change in one changes the other. Another way of saying this is that changing either our morality or our biology changes both—changes who we are and what we do.  相似文献

The original proposal of H. H. Pattee (1971) Pattee, H. H. 1971. “Can life explain quantum mechanics?”. In Quantum theory and beyond, Edited by: Bastin, T. 307319. Cambridge: Cambridge University Press.  [Google Scholar] of basing quantum theoretical measurement theory on the theory of the origin of life, and its far reaching consequences, is discussed in the light of a recently emerging biological paradigm of internal measurement. It is established that the “measurement problem” of quantum physics can, in principle, be traced back to the internal material constraints of the biological organisms, where choice is a fundamental attribute of the self-measurement of matter. In this light, which is shown to be a consequence of Pattee's original suggestion, it is proposed that biological evolution is a gradual liberation from the inert unity of “subject” and “object” of inanimate matter (as “natural law” and “initial conditions”), to a split biological existence of them and, as a consequence, the “message of evolution” is freedom, rather than complexity in itself. Some classical philosophical systems are brought into context to show that the epistemologies of several strictly philosophical systems of the social sciences are well acquainted with the problem and their solutions support our conclusions.  相似文献

Highly fluorescent silver nanoparticles (Ag-NPs), soluble in a ferroelectric host of polymer molecules such as poly(vinylidene fluoride) (PVF2), have been created in the form of nanofluids. The content of Ag-NPs (flocculates) is varied in steps 0.1–0.2 wt% up to a value of 5.0 wt% in tailoring a broad green emission band over 520–620 nm out of a hybrid percolation Ag–PVF2 composite. A maximum intensity arises in this band at as small a percolation threshold as ~0.1 wt% Ag-NPs. It contains three distinct bands of peak values 541, 565, and 582 nm in an Ag-NPs tunable response of the localized surface plasmons. The emission-dependent anti-Stokes excitation spectrum contains a similar group of three bands 348, 401, and 421 nm. For Ag-contents above 0.1 wt%, interdependent intensities in the emission and excitation bands drop rapidly by as much as five times, conferring a metal–polymer percolation network. The results open wide applications for biological labels and light emitters using such nanofluids.  相似文献

本研究采用访谈法,考查4~6岁儿童对生物的“人为不介入原理”的理解。研究结果表明:1.学前儿童没有表现出明显的“泛灵论”倾向。2.学前儿童对“人为不介入原理”的理解随年龄增长而呈现提高趋势,多数6岁儿童已经能够利用这一原理区分生物和非生物。3.学前儿童对不同领域刺激物的认知表现出不平衡性,对动物的认知优先发展,植物次之,对人造物认知的发展落后于对生物认知的发展。4.学前儿童表现出初步的分类概念。  相似文献
