Assumptions of science

The process of building scientific knowledge relies on a few basic assumptions that are worth acknowledging. Science operates on the assumptions that:   there are natural causes for things that happen in the world around us. For example, if a ball falls to the ground, science assumes that there must be a natural explanation for why the ball moves downward once released. Still, science assumes that there is an explanation for gravity that relies on natural causes, just as there is for everything in nature. Science assumes that we can learn about gravity and why a ball falls by studying evidence from the natural world. For example, science assumes that the gravitational forces at work on a falling ball are related to those at work on other falling objects. In fact, they form much of the basis for how we interact with the world and each other e operates on the assumptions that natural causes explain natural phenomena, that evidence from the natural world can inform us about those causes, and that these causes are page introduces the foundational assumptions of science.

You feel that your students are sufficiently ready (probably 10th-12th grade), you may want to share the following basic assumptions of science (and possibly the basic limitations of scientific knowledge, as well). These assumptions and limitations form the basis for the several key concepts of science and the handy “rules of science” mentioned elsewhere on the ensi assumptions of science. Contingent = depending on existing technology and current ways of d from “nature of modern science and scientific knowledge” by martin nickels, professor of science workspage 13 of 21previous |  as we might like to avoid it, all scientific tests involve making assumptions — many of them justified.

This test is straightforward, but still relies on many assumptions: we assume that the bacteria can grow on the growth medium, we assume that substance b does not affect bacterial growth, we assume that one day is long enough for colonies to grow, and we assume that the color pen we use to mark the outside of the dishes is not influencing bacterial growth. Technically, these are all assumptions, but they are perfectly reasonable ones that can be tested. The scientist performing the experiment described above would justify many of her assumptions by performing additional tests in parallel with the experimental ones. And some assumptions might remain untested simply because all of our knowledge about the field suggests that the assumption is a safe one (e. All tests involve assumptions, but most of these are assumptions that can and have been verified separately. Nevertheless, when evaluating an idea in light of test results, it's important to keep in mind the test's assumptions and how well-supported they are. And if the test results end up lending support to the idea, it might be because the idea is correct and should be accepted, or it might be because a violated assumption has produced a false positive scientific tests involve making assumptions can be independently tested, increasing our confidence in our test complex hypotheses — for example, regarding the earth's atmosphere — sometimes rely on many sub-hypotheses, or assumptions.

Er science / cial ical ational nmental nmental social nmental ionary atical / theoretical ophy of science is a sub-field of philosophy concerned with the foundations, methods, and implications of science. The central questions of this study concern what qualifies as science, the reliability of scientific theories, and the ultimate purpose of science. This discipline overlaps with metaphysics, ontology, and epistemology, for example, when it explores the relationship between science and is no consensus among philosophers about many of the central problems concerned with the philosophy of science, including whether science can reveal the truth about unobservable things and whether scientific reasoning can be justified at all. In addition to these general questions about science as a whole, philosophers of science consider problems that apply to particular sciences (such as biology or physics). Some philosophers of science also use contemporary results in science to reach conclusions about philosophy philosophical thought pertaining to science dates back at least to the time of aristotle, philosophy of science emerged as a distinct discipline only in the middle of the 20th century in the wake of the logical positivism movement, which aimed to formulate criteria for ensuring all philosophical statements' meaningfulness and objectively assessing them. 1] karl popper and charles sanders peirce moved on from positivism to establish a modern set of standards for scientific uently, the coherentist approach to science, in which a theory is validated if it makes sense of observations as part of a coherent whole, became prominent due to w. Some thinkers such as stephen jay gould seek to ground science in axiomatic assumptions, such as the uniformity of nature. A vocal minority of philosophers, and paul feyerabend (1924–1994) in particular, argue that there is no such thing as the "scientific method", so all approaches to science should be allowed, including explicitly supernatural ones. Another approach to thinking about science involves studying how knowledge is created from a sociological perspective, an approach represented by scholars like david bloor and barry barnes. Finally, a tradition in continental philosophy approaches science from the perspective of a rigorous analysis of human ophies of the particular sciences range from questions about the nature of time raised by einstein's general relativity, to the implications of economics for public policy. The general questions of philosophy of science also arise with greater specificity in some particular sciences.

The question of what counts as science and what should be excluded arises as a life-or-death matter in the philosophy of medicine. Additionally, the philosophies of biology, of psychology, and of the social sciences explore whether the scientific studies of human nature can achieve objectivity or are inevitably shaped by values and by social relations. Article: demarcation popper in the guishing between science and non-science is referred to as the demarcation problem. 3][4] martin gardner has argued for the use of a potter stewart standard ("i know it when i see it") for recognizing pseudoscience. Attempts by the logical positivists grounded science in observation while non-science was non-observational and hence meaningless. Area of study or speculation that masquerades as science in an attempt to claim a legitimacy that it would not otherwise be able to achieve is referred to as pseudoscience, fringe science, or junk science. 8] physicist richard feynman coined the term "cargo cult science" for cases in which researchers believe they are doing science because their activities have the outward appearance of it but actually lack the "kind of utter honesty" that allows their results to be rigorously evaluated. In this account, science is not about generalizing specific instances but rather about hypothesizing explanations for what is observed. Also: scientific realism and science aim to determine ultimate truth, or are there questions that science cannot answer? Scientific realists claim that science aims at truth and that one ought to regard scientific theories as true, approximately true, or likely true. Conversely, scientific anti-realists argue that science does not aim (or at least does not succeed) at truth, especially truth about unobservables like electrons or other universes.

In their view, whether theories are true or not is beside the point, because the purpose of science is to make predictions and enable effective ts often point to the success of recent scientific theories as evidence for the truth (or near truth) of current theories. 18][19] antirealists point to either the many false theories in the history of science,[20][21] epistemic morals,[22] the success of false modeling assumptions,[23] or widely termed postmodern criticisms of objectivity as evidence against scientific realism. Values emerge from science, both as product and process and can be distributed among several cultures in the it is unclear what counts as science, how the process of confirming theories works, and what the purpose of science is, there is considerable scope for values and other social influences to shape science. 26] feminist philosophers of science, sociologists of science, and others explore how social values affect also: history of scientific method, history of science, and history of origins of philosophy of science trace back to plato and aristotle[27] who distinguished the forms of approximate and exact reasoning, set out the threefold scheme of abductive, deductive, and inductive inference, and also analyzed reasoning by analogy. Bacon's statue at gray's inn, south square, s bacon (no direct relation to roger, who lived 300 years earlier) was a seminal figure in philosophy of science at the time of the scientific revolution. 31] in particular, later in the 18th century, david hume would famously articulate skepticism about the ability of science to determine causality and gave a definitive formulation of the problem of induction. Logical positivism accepts only testable statements as meaningful, rejects metaphysical interpretations, and embraces verificationism (a set of theories of knowledge that combines logicism, empiricism, and linguistics to ground philosophy on a basis consistent with examples from the empirical sciences). They also embraced russell's logical atomism, ernst mach's phenomenalism—whereby the mind knows only actual or potential sensory experience, which is the content of all sciences, whether physics or psychology—and percy bridgman's operationalism. The logical positivist movement became a major underpinning of analytic philosophy,[34] and dominated anglosphere philosophy, including philosophy of science, while influencing sciences, into the 1960s. Nevertheless, it brought about the establishment of philosophy of science as a distinct subdiscipline of philosophy, with carl hempel playing a key role. Article: the structure of scientific kuhn, the addition of epicycles in ptolemaic astronomy was "normal science" within a paradigm, whereas the copernican revolution was a paradigm the 1962 book the structure of scientific revolutions, thomas kuhn argued that the process of observation and evaluation takes place within a paradigm, a logically consistent "portrait" of the world that is consistent with observations made from its framing.

He characterized normal science as the process of observation and "puzzle solving" which takes place within a paradigm, whereas revolutionary science occurs when one paradigm overtakes another in a paradigm shift. Thinkers seek to articulate axiomatic assumptions on which science may be based, a form of foundationalism. This is typically the implicit philosophy of working scientists, that the following basic assumptions are needed to justify the scientific method:That there is an objective reality shared by all rational observers;. For instance, hugh gauch argues that science presupposes that "the physical world is orderly and comprehensible. Lavender in contrast to the view that science rests on foundational assumptions, coherentism asserts that statements are justified by being a part of a coherent system. Article: epistemological feyerabend (1924–1994) argued that no description of scientific method could possibly be broad enough to include all the approaches and methods used by scientists, and that there are no useful and exception-free methodological rules governing the progress of science. Said that science started as a liberating movement, but that over time it had become increasingly dogmatic and rigid and had some oppressive features. Because of this, he said it was impossible to come up with an unambiguous way to distinguish science from religion, magic, or mythology. He saw the exclusive dominance of science as a means of directing society as authoritarian and ungrounded. 48] promulgation of this epistemological anarchism earned feyerabend the title of "the worst enemy of science" from his detractors. Article: sociology of scientific ing to kuhn, science is an inherently communal activity which can only be done as part of a community.

50] for him, the fundamental difference between science and other disciplines is the way in which the communities function. Others, especially feyerabend and some post-modernist thinkers, have argued that there is insufficient difference between social practices in science and other disciplines to maintain this distinction. For them, social factors play an important and direct role in scientific method, but they do not serve to differentiate science from other disciplines. On this account, science is socially constructed, though this does not necessarily imply the more radical notion that reality itself is a social r, some (such as quine) do maintain that scientific reality is a social construct:Physical objects are conceptually imported into the situation as convenient intermediaries not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the gods of homer ... Public backlash of scientists against such views, particularly in the 1990s, became known as the science wars. 53] here the approach to the philosophy of science is to study how scientific communities actually ental philosophy[edit]. However, they have much to say about science, some of which has anticipated themes in the analytical tradition. For example, friedrich nietzsche advanced the thesis in his "the genealogy of morals" that the motive for search of truth in sciences is a kind of ascetic ideal. With his berlin by franz general, science in continental philosophy is viewed from a world-historical perspective. Philosophers such as pierre duhem and gaston bachelard also wrote their works with this world-historical approach to science, predating kuhn by a generation or more. All of these approaches involve a historical and sociological turn to science, with a priority on lived experience (a kind of husserlian "life-world"), rather than a progress-based or anti-historical approach as done in the analytic tradition.

Largest effect on the continental tradition with respect to science was martin heidegger's critique of the theoretical attitude in general which of course includes the scientific attitude. 56] for this reason the continental tradition has remained much more skeptical of the importance of science in human life and philosophical inquiry. Another important development was that of michel foucault's analysis of the historical and scientific thought in the order of things and his study of power and corruption within the "science" of madness. Post-heideggerian authors contributing to the continental philosophy of science in the second half of the 20th century include jürgen habermas (e. Broad issue affecting the neutrality of science concerns the areas which science chooses to explore, that is, what part of the world and man is studied by science. Philip kitcher in his "science, truth, and democracy"[59] argues that scientific studies that attempt to show one segment of the population as being less intelligent, successful or emotionally backward compared to others have a political feedback effect which further excludes such groups from access to science. Thus such studies undermine the broad consensus required for good science by excluding certain people, and so proving themselves in the end to be ophy of particular sciences[edit]. Is no such thing as philosophy-free science; there is only science whose philosophical baggage is taken on board without examination. Daniel dennett, darwin's dangerous idea, addition to addressing the general questions regarding science and induction, many philosophers of science are occupied by investigating foundational problems in particular sciences. The late 20th and early 21st century has seen a rise in the number of practitioners of philosophy of a particular science. Article: philosophy of ophy of chemistry is the philosophical study of the methodology and content of the science of chemistry.

Article: philosophy of ophy of biology deals with epistemological, metaphysical, and ethical issues in the biological and biomedical sciences. 66] philosophers of science began to pay increasing attention to developments in biology, from the rise of the modern synthesis in the 1930s and 1940s to the discovery of the structure of deoxyribonucleic acid (dna) in 1953 to more recent advances in genetic engineering. Other key ideas such as the reduction of all life processes to biochemical reactions as well as the incorporation of psychology into a broader neuroscience are also addressed. Even if two individuals respond with the same answer on a likert scale, they may be experiencing very different issues in philosophy of psychology are philosophical questions about the nature of mind, brain, and cognition, and are perhaps more commonly thought of as part of cognitive science, or philosophy of mind. Philosophy of psychology also closely monitors contemporary work conducted in cognitive neuroscience, evolutionary psychology, and artificial intelligence, questioning what they can and cannot explain in ophy of psychology is a relatively young field, because psychology only became a discipline of its own in the late 1800s. Notable recent development in philosophy of psychology is functional contextualism or contextual behavioural science (cbs). It is most actively developed in behavioral science in general, the field of behavior analysis, and contextual behavioral science in particular (see the entry for the association for contextual behavioral science). The philosopher of science and medicine dominic murphy identifies three areas of exploration in the philosophy of psychiatry. The first concerns the examination of psychiatry as a science, using the tools of the philosophy of science more broadly. 82] the first concerns the definition and scope of economics and by what methods it should be studied and whether these methods rise to the level of epistemic reliability associated with the other special sciences. Article: philosophy of social philosophy of social science is the study of the logic and method of the social sciences, such as sociology, anthropology, and political science.

83] philosophers of social science are concerned with the differences and similarities between the social and the natural sciences, causal relationships between social phenomena, the possible existence of social laws, and the ontological significance of structure and french philosopher, auguste comte (1798–1857), established the epistemological perspective of positivism in the course in positivist philosophy, a series of texts published between 1830 and 1842. The first three volumes of the course dealt chiefly with the physical sciences already in existence (mathematics, astronomy, physics, chemistry, biology), whereas the latter two emphasised the inevitable coming of social science: "sociologie". 84] for comte, the physical sciences had necessarily to arrive first, before humanity could adequately channel its efforts into the most challenging and complex "queen science" of human society itself. Durkheim, marx, and weber are more typically cited as the fathers of contemporary social science. Positivism has also been espoused by 'technocrats' who believe in the inevitability of social progress through science and technology. Positivist perspective has been associated with 'scientism'; the view that the methods of the natural sciences may be applied to all areas of investigation, be it philosophical, social scientific, or otherwise. Today, practitioners of both social and physical sciences instead take into account the distorting effect of observer bias and structural limitations. This scepticism has been facilitated by a general weakening of deductivist accounts of science by philosophers such as thomas kuhn, and new philosophical movements such as critical realism and neopragmatism. Defining pseudoscience", philosophia naturalis, 33: 169–176, as cited in "science and pseudo-science" (2008) in stanford encyclopedia of philosophy. The stanford article states: "many writers on pseudoscience have emphasized that pseudoscience is non-science posing as science. The foremost modern classic on the subject (gardner 1957) bears the title fads and fallacies in the name of science.

2006 national science foundation report on science and engineering indicators quoted michael shermer's (1997) definition of pseudoscience: '"claims presented so that they appear [to be] scientific even though they lack supporting evidence and plausibility"(p. In contrast, science is "a set of methods designed to describe and interpret observed and inferred phenomena, past or present, and aimed at building a testable body of knowledge open to rejection or confirmation"(p. A pretended or spurious science; a collection of related beliefs about the world mistakenly regarded as being based on scientific method or as having the status that scientific truths now have," from the oxford english dictionary, second edition 1989. Douglas allchin, "values in science and in science education," in international handbook of science education, b. But as the new tradition in the philosophy of science began to demonstrate its effectiveness—by dissolving and rephrasing old problems as well as by generating new ones—philosophers began to shift allegiances to the new tradition, even though that tradition has yet to receive a canonical formulation. However, neo-positivism failed dismally to give a faithful account of science, whether natural or social. Although it has never been practiced consistently in the advanced natural sciences and has been criticized by many philosophers, notably popper (1959 [1935], 1963), logical positivism remains the tacit philosophy of many scientists. Regrettably, the anti-positivism fashionable in the metatheory of social science is often nothing but an excuse for sloppiness and wild speculation. 154, "expressed as a single grand statement, science presupposes that the physical world is orderly and comprehensible. The 'war' is between scientists who believe that science and its methods are objective, and an increasing number of social scientists, historians, philosophers, and others gathered under the umbrella of science studies.
