The Structure of Scientific Revolutions - Wikipedia, the free encyclopedia - 1 views

  • The Structure of Scientific Revolutions by Thomas S. Kuhn, is an analysis of the history of science, published in 1962 by the University of Chicago Press. Its publication was a landmark event in the history, philosophy, and sociology of scientific knowledge and it triggered an ongoing worldwide assessment and reaction in—and beyond—those scholarly communities. In this work, Kuhn challenged the then prevailing view of progress in "normal science". Scientific progress had been seen primarily as "development-by-accumulation" of accepted facts and theories. Kuhn argued for an episodic model in which periods of such conceptual continuity in normal science were interrupted by periods of revolutionary science.
  • What is arguably the most famous example of a revolution in scientific thought is the Copernican Revolution. In Ptolemy's school of thought, cycles and epicycles (with some additional concepts) were used for modeling the movements of the planets in a cosmos that had a stationary Earth at its center. As accuracy of celestial observations increased, complexity of the Ptolemaic cyclical and epicyclical mechanisms had to increase to maintain the calculated planetary positions close to the observed positions. Copernicus proposed a cosmology in which the Sun was at the center and the Earth was one of the planets revolving around it.
  • Copernicus' contemporaries rejected his cosmology, and Kuhn asserts that they were quite right to do so: Copernicus' cosmology lacked credibility.

  • One of the aims of science is to find models that will account for as many observations as possible within a coherent framework. Together, Galileo's rethinking of the nature of motion and Keplerian cosmology represented a coherent framework that was capable of rivaling the Aristotelian/Ptolemaic framework.
  • In any community of scientists, Kuhn states, there are some individuals who are bolder than most. These scientists, judging that a crisis exists, embark on what Thomas Kuhn calls revolutionary science, exploring alternatives to long-held, obvious-seeming assumptions. Occasionally this generates a rival to the established framework of thought. The new candidate paradigm will appear to be accompanied by numerous anomalies, partly because it is still so new and incomplete. The majority of the scientific community will oppose any conceptual change, and, Kuhn emphasizes, so they should. To fulfill its potential, a scientific community needs to contain both individuals who are bold and individuals who are conservative.
  • Those scientists who possess an exceptional ability to recognize a theory's potential will be the first whose preference is likely to shift in favour of the challenging paradigm. There typically follows a period in which there are adherents of both paradigms. In time, if the challenging paradigm is solidified and unified, it will replace the old paradigm, and a paradigm shift will have occurred.
  • Chronologically, Kuhn distinguishes between three phases. The first phase, which exists only once, is the pre-paradigm phase, in which there is no consensus on any particular theory, though the research being carried out can be considered scientific in nature. This phase is characterized by several incompatible and incomplete theories.
  • If the actors in the pre-paradigm community eventually gravitate to one of these conceptual frameworks and ultimately to a widespread consensus on the appropriate choice of methods, terminology and on the kinds of experiment that are likely to contribute to increased insights, then the second phase, normal science, begins, in which puzzles are solved within the context of the dominant paradigm. As long as there is consensus within the discipline, normal science continues.
  • Over time, progress in normal science may reveal anomalies, facts that are difficult to explain within the context of the existing paradigm. While usually these anomalies are resolved, in some cases they may accumulate to the point where normal science becomes difficult and where weaknesses in the old paradigm are revealed. Kuhn refers to this as a crisis. Crises are often resolved within the context of normal science. However, after significant efforts of normal science within a paradigm fail, science may enter the third phase, that of revolutionary science, in which the underlying assumptions of the field are reexamined and a new paradigm is established. After the new paradigm's dominance is established, scientists return to normal science, solving puzzles within the new paradigm.
  • SSR is viewed by postmodern and post-structuralist thinkers as having called into question the enterprise of science by demonstrating that scientific knowledge is dependent on the culture and historical circumstances of groups of scientists rather than on their adherence to a specific, definable method.
  • SSR has also been embraced by creationists who see creationism as an incommensurate worldview in contrast to naturalism while holding science as a valuable tool.[7]

Michael Shermer: What Is Skepticism, Anyway? - 1 views

  • Consider global warming: Are you a global warming skeptic? Or are you skeptical of the global warming skeptics? In this case, I used to be a global warming skeptic, but now I'm skeptical of the global warming skeptics, which makes me a global warming believer based on the facts as I understand them at the moment. The "at the moment" part is what makes conclusions in science and skepticism provisional.
  • Thus, science and skepticism are synonymous, and in both cases it's okay to change your mind if the evidence changes. It all comes down to this question: What are the facts in support or against a particular claim?
  • Being a skeptic just means being rational and empirical: thinking and seeing before believing.
  • ...3 more annotations...
  • Skepticism is not "seek and ye shall find," but "seek and keep an open mind."
  • Skepticism is the rigorous application of science and reason to test the validity of any and all claims.
  • Typically pseudoscientists will make statements that are unverified, or verified by a source within their own belief circle.
  •  
    This Article highlights the connection between skepticism, science, and belief.  This dovetails with our discussion of paradigm shifts and how scientific results gain credibility through the peer review process where the data and methods are scrutinized along with the truth claims by qualified peers.

eHRAF World Cultures - 0 views

  •  
    WE PEOPLE OF THE UNITED STATES ARE A MIXED BREED. WE HAVE COME from all parts of the world; all races of men compose our biological aggregate. We have created an official ideology to fit this condition which declares than men of all races and all cultures are equally precious in the eyes of God and are, therefore, equal,-and here we pause for a long afterthought-"At least, they should be equal, in the thoughts and actions of men." In the second thought we see the ever-present basic conflict that permeates our way of life: a deep faith in the principles of equality which we proudly proclaim, and a fundamental, unofficial, unacknowledged, and almost guilty belief that certain Americans are the "real" ones and superior, while all others are second-class citizens and inferior. Our communities' social systems reflect this conflict when attempting to organize the lives of men who hold these opposing beliefs. Commonsense observation of these communities, buttressed by the more exact findings of social science, demonstrates that despite our equalitarian credo two types of separate and subordinate groups have emerged in the United States. All dark-skinned races with Mongoloid or Negroid ancestry are placed by our social system in subordinate groups, and all deviant cultural groups, speaking different languages, professing different faiths, and exhibiting exotic manners and customs are set apart and classed as inferior.

Perspectives on Tierney's Darkness in El Dorado - 2 views

    "This would be unfortunate, for the book offers a controversial account of the impact of Western research on an indigenous population that should urge us to think hard about our work. Even before its publication, Darkness in El Dorado became a Janusfaced text that in calling attention to methodological and ethical shortcomings of scientific research in the Amazon also brought attention to faults in its own production. This should not obscure its contribution or make us forget that the central issue in this drama, after all, should be the Yanomami" "At the books heart is a twostranded argument concerning the work among the Yanomami by the anthropologist Napoleon Chagnon and the geneticist James Neel. One strand follows their involvement in a complex set of medical practices centering on the collection of blood samples and a measles vaccination campaign. The other traces Chagnons spectacular career as the creator of the Yanomami as anthropologys wellknown fierce people. While Tierneys focus is on individuals, his book locates them in two relevant contexts: the cold war and the Vietnam War, during which currents of evolutionary genetics, sociobiology, and cultural anthropology claiming that aggression plays a positive role in human evolution found broad support, and the Venezuelan petrostate culture of clientelism, which fostered a network of corrupt politicians and businessmen with interests in the Yanomami and their territory for reasons of profit and power. His discussion argues that the work of Chagnon, Neel, and other scientists brought the Yanomami neither empowerment nor wellbeing but fragmentation and destruction" "The first strand of the book, which occupies less than onetenth of Tierneys text but has received the most public attention, argues that Neel and Chagnon collected blood samples for the Atomic Energy Commission to compare mutation rates in populations contaminated by radiation with those in one uncontaminated by it and at the same time carried out

On Reflections on Darkness in El Dorado - 0 views

    "However, some important points are mistaken or missing. Contrary to Alan Fix, research on Yanomami began not in the 1960s but as early as 1800. Now there are more than 60 books, albeit of widely varying quality, on aspects of Yanomami. Sufficient literature exists to recognize a field of specializationYanomami Studies or Yanomamology. It is possible to identify points of agreement and disagreement among the numerous and diverse writers who have published on Yanomami and draw conclusions" "None of some 60 books previously published on the Yanomami ever drew attention to the violations of professional ethics and abuses of human rights by anthropologists in the ways and to the extent that Tierney does. Not one of those books was subjected to a panel discussion and open forum at any AAA convention, any forum in a journal like CA, investigations in three countries, discussions in international media and cyberspace, etc" "Tierney exposed the ugliest affair in the entire history of anthropology. It cannot be summarily dismissed by a vocal minority as simply a matter of personal animosities, turf war, postmodernist critique of science or scientism, objectivist versus activist, differing interpretations of Yanomami aggression, sensationalist or tabloid journalism, etc. As Susan Lindee recognizes and contrary to Raymond Hames, not all of the fundamental claims made by Tierney have been discussed, let alone refuted."

  • Korean, in contrast, conflates Motion with Path and elements of Figure and Ground in transitive clauses for caused Motion, but conflates motion with Deixis and spells out Path and Manner separately in intransitive clauses for spontaneous motion.
  • sensitivity to language-specific patterns in the way they talk about motion from as early as 17–20 months.
  • learners of English quickly generalize their earliest spatial words — Path particles like up, down, and in — to both spontaneous and caused changes of location and, for up and down, to posture changes, while learners of Korean keep words for spontaneous and caused motion strictly separate and use different words for vertical changes of location and posture changes.

  • Does the language you speak affect how you think about the world?
  • English and Mandarin talk about time differently—English predominantly talks about time as if it were horizontal, while Mandarin also commonly describes time as vertical
  • Another study showed that the extent to which Mandarin–English bilinguals think about time vertically is related to how old they were when they first began to learn English.
  • ...3 more annotations...
  • In another experiment native English speakers were taught to talk about time using vertical spatial terms in a way similar to Mandarin.
  • language is a powerful tool in shaping thought about abstract domains and
  • one's native language plays an important role in shaping habitual thought (e.g., how one tends to think about time) but does not entirely determine one's thinking in the strong Whorfian sense.
