I examine the development of Charles Lyell's principle of uniformity and its influence on the development of modern geology and biology and argue that distinguishing between philosophical starting points and empirical findings is essential for clarity in the discussion between science and religion. First, I explore Lyell's arguments against catastrophism and how these were both empirically and religiously motivated. I then consider how David Hume's empiricism, theory of causation, and rejection of miracles influenced Lyell. Using these insights, Lyell formulated his principle of uniformity, which he believed was based on current empirical findings, and rejected explanatory hypotheses that used the biblical Flood or other catastrophist accounts as violations of uniform causation and introductions of theological concepts into empirical science. I next examine the influence of Lyell's principle on Charles Darwin. Although Lyell opposed Darwinism for most of his life, Darwin relied heavily on Lyell, as is evidenced by references throughout The Origin of Species. I contend that the most important aspect of Lyell's principle for Darwin is that it makes natural evil (the struggle for survival) a process that has always been occurring rather than something introduced after the Fall as recorded in Genesis. Finally, I discuss the role that uniformity plays for Lyell, Darwin, and modern science as an interpretive principle rather than as an inference from empirical data, and I conclude by noting that keeping the distinction in mind between interpretive principles and empirical findings will help clarify debates between science and religion. 相似文献

James Drane's More Humane Medicine: A Liberal Catholic Bioethics is an outstanding contribution to the study of bioethics in our day. Catholics and others who are interested in the issues discussed here will benefit from this masterful treatment. The author opens with a set of definitions, starting with what he means by a "more humane medicine." Drane contends that a more humane medicine has become necessary and desired, but not because the traditional medical ethic as "a self-declared and self-imposed ethic, outlining what noble service to others entails" is no longer valid. Rather he defines it as an advance on the traditional ethic; a "new foundation" based on a "lived set of obligations derived from a felt commitment to other persons ... an ethics based on the relationship between doctors and patients and essentially an ethics of virtue." Drane's work is a "liberal Catholic Bioethics" in which he challenges his own faith tradition, the Roman Catholic Church, on such topics as sexuality, birth control, abortion, cloning, stem cell research, aging and dying, and euthanasia and physician-assisted suicide. The present article is a critical essay that analyzes the author's statements and conclusions. 相似文献

Natural concepts in a juvenile gorilla (gorilla gorilla gorilla) at three levels of abstraction

The extent to which nonhumans are able to form conceptual versus perceptual discriminations remains a matter of debate. Among the great apes, only chimpanzees have been tested for conceptual understanding, defined as the ability to form discriminations not based solely on simple perceptual features of stimuli, and to transfer this learning to novel stimuli. In the present investigation, a young captive female gorilla was trained at three levels of abstraction (concrete, intermediate, and abstract) involving sets of photographs representing natural categories (e.g., orangutans vs. humans, primates vs. nonprimate animals, animals vs. foods). Within each level of abstraction, when the gorilla had learned to discriminate positive from negative exemplars in one set of photographs, a novel set was introduced. Transfer was defined in terms of high accuracy during the first two sessions with the new stimuli. The gorilla acquired discriminations at all three levels of abstraction but showed unambiguous transfer only with the concrete and abstract stimulus sets. Detailed analyses of response patterns revealed little evidence of control by simple stimulus features. Acquisition and transfer involving abstract stimulus sets suggest a conceptual basis for gorilla categorization. The gorilla's relatively poor performance with intermediate-level discriminations parallels findings with pigeons, and suggests a need to reconsider the role of perceptual information in discriminations thought to indicate conceptual behavior in nonhumans. 相似文献

Denying Diversity: Perceptions of Beauty and Social Comparison Processes Among Latina,Black, and White Women 总被引:1,自引:0,他引:1
The purpose of this study was to investigate Latina, Black, and White women's conceptions of beauty and perceptions of cultural standards of beauty, as well as whether or not the participants were engaging in similar social comparison processes, specifically, the denial of personal disadvantage. One hundred and fifty-seven college women participated: 48 Latinas, 52 Black women, 51 White women, and 6 Others. Results indicate that there are significant differences in Latinas', Black women's, and White women's relationships with their bodies, and their relationships to dominant cultural standards of beauty. In addition, there were differences by race in the tendency to engage in the denial of personal disadvantage response. These findings contribute to the understanding of how racial identity affects, or interacts with, the experience of beauty standards among Latina, Black, and White women. 相似文献
