Philosophy of science is the study of assumptions, foundations, and implications of science. The philosophy of science may be divided into two areas: Epistemology ofscience and metaphysics of science.

Philosophers of science are interested in: the history ofconcepts and terms and how they are currently used in science; the relation between propositions with arguments(Formal logic); the reasoning connecting hypotheses and conclusions (Scientific method); the manner in which science explains natural phenomena and predicts natural occurrences (observation); the types of reasoning that are used to arrive at scientific conclusions (deduction, induction, abduction); the formulation, scope, and limitsof scientific understanding; the means that should be used for determining when scientific information has adequate support (objectivity); and the implications of scientific methods and models, along with the technology that arises from scientific knowledge for the larger society (applied science).

Issues of ethics, such as bioethics and scientific misconduct, are not generally considered part of philosophy of science. These issues may be studied in ethics or science studies.

Nature of scientific concepts and statementsScience draws logical conclusions about the way the worldworks and the way in which scientific theory relates to the world. Science draws upon evidence from experimentation, logical deduction, and rational thought in order to examine the world. In making observations of the nature of individuals and their surroundings, scienceseeks to explain the concepts that are entwined with everyday lives. Science in general is neither "natural" in its approach nor moral in its purpose. It's simply science: the application of a logic (often in form of mathematics) to a set of objects or situations. In a fundamental sense science is just a logic.

Objectivity of observations in science

It is vitally important for science that the information about the surrounding world and the objects of study be as accurate and as reliable as possible. For the sake of this, measurements which are the source of this information must be as objective as possible. Before the invention of measuring tools (like weights, meter sticks,clocks, etc) the only source of information available to humans were their senses (vision, hearing, taste, tactile, sense of heat, sense of gravity, etc.). Because human senses differ from person to person (due to wide variations in personal chemistry, deficiencies, inheritedflaws, etc) there was no objective measurements before the invention of these tools. The consequence of this wasthe lack of a vigorous science.

With the advent of exchange of goods, trades, and agricultures there arose a need in such measurements, andscience (arithmetics, geometry, mechanics, etc) based on standardized units of measurements (stadia, pounds, seconds, etc) was born. To further abstract from unreliable human senses and make measurements more objective, science uses measuring devices (like spectrometers, voltmeters, interferometers, thermocouples, counters, etc) and lately - computers. In

3

most cases, the less human involvement in measuring process, the more accurate and reliable scientific data are. Currently most measurements are done by variety of mechanical and electronic sensors directly linked to computers—which further reduces chance of human error/contamination of information. This made possible toachieve astonishing accuracy of modern measurements. For example, current accuracy of measurement of mass is about10-10, of angles—about 10-9, and of time and length intervals in many cases reaches the order of 10-13 - 10-15. This made possible to measure, say, distance to Moon withsub-centimeter accuracy (see Lunar laser ranging experiment), to measure slight movement of tectonic plates using GPS system with sub-millimeter accuracy, or even to measure as slight variations in the distance between two mirrors separated by several kilometers as 10-

18 m—three orders of magnitude less than the size of a single atomic nucleus—see LIGO.

Theory-dependence of observation

A scientific method depends on objective observation in defining the subject under investigation, gaining information about its behavior and in performing experiments.

Observation involves perception as well as a cognitive process. That is, one does not make an observation passively, but is actively involved in distinguishing thething being observed from surrounding sensory data. Therefore, observations depend on some underlying understanding of the way in which the world functions, and that understanding may influence what is perceived, noticed, or deemed worthy of consideration. (See the Sapir-Whorf hypothesis for an early version of this understanding of the impact of cultural artifacts on our perceptions of the world.)

Empirical observation is supposedly used to determine theacceptability of some hypothesis within a theory. When someone claims to have made an observation, it is reasonable to ask them to justify their claim. Such a justification must make reference to the theory -

4

operational definitions and hypotheses - in which the observation is embedded. That is, the observation is a component of the theory that also contains the hypothesisit either verifies or falsifies. But this means that the observation cannot serve as a neutral arbiter between competing hypotheses. Observation could only do this "neutrally" if it were independent of the theory.

Thomas Kuhn denied that it is ever possible to isolate the theory being tested from the influence of the theory in which the observations are grounded. He argued that observations always rely on a specific paradigm, and thatit is not possible to evaluate competing paradigms independently. By "paradigm" he meant, essentially, a logically consistent "portrait" of the world, one that involves no logical contradictions. More than one such logically consistent construct can each paint a usable likeness of the world, but it is pointless to pit them against each other, theory against theory. Neither is a standard by which the other can be judged. Instead, the question is which "portrait" is judged by some set of people to promise the most in terms of “puzzle solving”.

For Kuhn, the choice of paradigm was sustained by, but not ultimately determined by, logical processes. The individual's choice between paradigms involves setting two or more “portraits" against the world and deciding which likeness is most promising. In the case of a general acceptance of one paradigm or another, Kuhn believed that it represented the consensus of the community of scientists. Acceptance or rejection of some paradigm is, he argued, more a social than a logical process.

That observation is embedded in theory does not mean thatobservations are irrelevant to science. Scientific understanding derives from observation, but the acceptance of scientific statements is dependent on the related theoretical background or paradigm as well as on observation. Coherentism and skepticism offer alternatives to foundationalism for dealing with the difficulty of grounding scientific theories in something more than observations.

Indeterminacy of theory under empirical testing

According to the Duhem–Quine thesis, after Pierre Duhem and W.V. Quine, any theory can be made compatible with any empirical observation by the addition of suitable ad hoc hypotheses. This is analogous to the way in which an infinite number of curves can be drawn through any finiteset of data points on a graph.

This thesis was accepted by Karl Popper, leading him to reject naïve falsification in favour of 'survival of the fittest', or most falsifiable, of scientific theories. InPopper's view, any hypothesis that does not make testablepredictions is simply not science. Such a hypothesis may be useful or valuable, but it cannot be said to be science. Confirmation holism, developed by W.V. Quine, states that empirical data are not sufficient to make a judgement between theories. In this view, a theory can always be made to fit with the available empirical data. However, that empirical evidence does not serve to determine between alternative theories does not necessarily imply that all theories are of equal value, as scientists often use guiding principles such as Occam's Razor.

One result of this view is that specialists in the philosophy of science stress the requirement that observations made for the purposes of science be restricted to intersubjective objects. That is, science is restricted to those areas where there is general agreement on the nature of the observations involved. It is comparatively easy to agree on observations of physical phenomena, harder for them to agree on observations of social or mental phenomena, and difficultin the extreme to reach agreement on matters of theology or ethics (and thus the latter remain outside the normal purview of science).

Empiricism

6

A central concept in the philosophy of science is empiricism, or dependence on evidence. Empiricism is the view that knowledge is derived from our experiences throughout our lives. In this sense, scientific statements are subject to and derived from our experiences or observations. Scientific hypotheses are developed and tested through empirical methods consistingof observations and experiments. Once reproduced widely enough, the information resulting from our observations and experiments counts as the evidence upon which the scientific community develops theories that purport to explain facts about the world.

Observations involve perception, and so are themselves cognitive acts. That is, observations are themselves embedded in our understanding of the way in which the world works; as this understanding changes, the observations themselves may apparently change. More accurately, our interpretation of observations may change. A well designed experiment will produce identicalresults when carried out in an identical fashion. Whenever the social context of the observer is a factor in an observation, objectivity is lost, and the observation is no longer useful in a scientific sense.

Scientists attempt to use induction, deduction and quasi-empirical methods, and invoke key conceptual metaphors towork observations into a coherent, self-consistent structure.

Scientific realism and instrumentalism

Scientific realism is the view that the universe really is as explained by scientific statements. Realists hold that things like electrons and magnetic fields actually exist. In contrast to realism, instrumentalism holds thatour perceptions, scientific ideas and theories do not necessarily reflect the real world accurately, but are useful instruments to explain, predict and control our experiences. To an instrumentalist, electrons and magnetic fields are convenient ideas that may or may not actually exist. For instrumentalists, the empirical method is used to do no more than show that theories are

7

consistent with observations. Instrumentalism is largely based on John Dewey's philosophy and, more generally, pragmatism, which was influenced by philosophers such as William James and Charles Sanders Peirce.

Constructivism

Main article: Constructivist epistemology

Constructivism is a view in philosophy according to whichall knowledge is "constructed" inasmuch as it is contingent on convention, human perception, and social experience.[citation needed] It originated in sociology under the term "social constructionism" and has been given the name"constructivism" when referring to philosophical epistemology, though "constructionism" and "constructivism" are often used interchangeably.[citation needed] In many ways, its views are similar to instrumentalism and pragmatism, or can appear so from the perspective of scientific realism. For this reason, and because of its association with relativism, the constructivist view of the philosophy of science is not widely accepted among scientists and has been criticized by realists in both the scientific and philosophical communities.[1][2][3][4][5] (see also: Science wars, Anti-realism)

Analysis and reductionism

Analysis is the activity of breaking an observation or theory down into simpler concepts in order to understand it. Analysis is as essential to science as it is to all rational enterprises. It would be impossible, for instance, to describe mathematically the motion of a projectile without separating out the force of gravity, angle of projection and initial velocity. Only after thisanalysis is it possible to formulate a suitable theory ofmotion.

Reductionism in science can have several different senses. One type of reductionism is the belief that all fields of study are ultimately amenable to scientific explanation. Perhaps a historical event might be explained in sociological and psychological terms, which

8

in turn might be described in terms of human physiology, which in turn might be described in terms of chemistry and physics. The historical event will have been reduced to a physical event. This might be seen as implying that the historical event was 'nothing but' the physical event, denying the existence of emergent phenomena.

Daniel Dennett invented the term greedy reductionism to describe the assumption that such reductionism was possible. He claims that it is just 'bad science', seeking to find explanations which are appealing or eloquent, rather than those that are of use in predictingnatural phenomena. He also says that:

There 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, 1995.

Arguments made against greedy reductionism through reference to emergent phenomena rely upon the fact that self-referential systems can be said to contain more information than can be described through individual analysis of their component parts. Examples include systems that contain strange loops, fractal organisation and strange attractors in phase space. Analysis of such systems is necessarily information-destructive because the observer must select a sample of the system that can be at best partially representative. Information theory can be used to calculate the magnitude of information loss and is one of the techniques applied by Chaos theory.

Grounds of validity of scientific reasoningThe most powerful statements in science are those with the widest applicability. Newton's Third Law — "for everyaction there is an opposite and equal reaction" — is a powerful statement because it applies to every action, anywhere, and at any time.

9

But it is not possible for scientists to have tested every incidence of an action, and found a reaction. How is it, then, that they can assert that the Third Law is in some sense true? They have, of course, tested many, many actions, and in each one have been able to find the corresponding reaction. But can we be sure that the next time we test the Third Law, it will be found to hold true?

Induction

One solution to this problem is to rely on the notion of induction. Inductive reasoning maintains that if a situation holds in all observed cases, then the situation holds in all cases. So, after completing a series of experiments that support the Third Law, one is justified in maintaining that the Law holds in all cases.

Explaining why induction commonly works has been somewhatproblematic. One cannot use deduction, the usual process of moving logically from premise to conclusion, because there is simply no syllogism that will allow such a move.No matter how many times 17th century biologists observedwhite swans, and in how many different locations, there is no deductive path that can lead them to the conclusionthat all swans are white. This is just as well, since, asit turned out, that conclusion would have been wrong. Similarly, it is at least possible that an observation will be done tomorrow that shows an occasion in which an action is not accompanied by a reaction; the same is trueof any scientific law.

One answer has been to conceive of a different form of rational argument, one that does not rely on deduction. Deduction allows one to formulate a specific truth from ageneral truth: all crows are black; this is a crow; therefore this is black. Induction somehow allows one to formulate a general truth from some series of specific observations: this is a crow and it is black; that is a crow and it is black; therefore all crows are black.

10

The problem of induction is one of considerable debate and importance in the philosophy of science: is inductionindeed justified, and if so, how?

Falsifiability

Main article: Falsifiability

Another way to distinguish science from pseudoscience (e.g. astronomy from astrology), first formally discussedby Karl Popper in 1919-20 and reformulated by him in the 1960s, is falsifiability. This principle states that in order to be useful (or even scientific at all), a scientific statement ('fact', theory, 'law', principle, etc) must be falsifiable, that is, able to be tested and proven wrong.

Popper described falsifiability using the following observations, paraphrased from a 1963 essay on "Conjectures and Refutations":

1. It is easy to confirm or verify nearly every theory — if we look for confirmations.

2. Confirmations are significant only if they are the result of risky predictions; that is, if, unenlightened by the theory, we should have expectedan event which was incompatible with the theory — anevent which would have refuted the theory.

3. "Good" scientific theories include prohibitions which forbid certain things to happen. The more a theory forbids, the better it is.

4. A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory.

5. Every genuine test of a theory is an attempt to falsify or refute it. Theories that take greater "risks" are more testable, more exposed to refutation.

6. Confirming or corroborating evidence is only significant when it is the result of a genuine test of the theory; "genuine" in this case means that it comes out of a serious but unsuccessful attempt to falsify the theory.

11

7. Some genuinely testable theories, when found to be false, are still upheld by their advocates — for example by introducing ad hoc some auxiliary assumption, or by reinterpreting the theory ad hoc in such a way that it escapes refutation. Such a procedure is always possible, but it rescues the theory from refutation only at the price of destroying, or at least lowering, its scientific status.

These observations are part of Popper's case for defending the idea that what makes a theory scientific isits falsifiability, or refutability. However, Popper's ideas have been heavily criticized by many philosophers, especially on the grounds that they do not adequately describe scientific activity. For instance, very few scientific theories specifically forbid events from happening, which are not open to ad-hoc adjustments (3 above). Similarly, taken in a strict sense, no theory is refutable on the basis of an event (at least not without a guiding set of background theories and ad-hoc restrictions). Nevertheless, Popper's notion of falisiability remains a cornerstone of the personal philosophy of many working scientists, e.g. Stephen Hawking.

Coherentism

Induction and falsification both attempt to justify scientific statements by reference to other specific scientific statements. Both must avoid the problem of thecriterion, in which any justification must in turn be justified, resulting in an infinite regress. The regress argument has been used to justify one way out of the infinite regress, foundationalism. Foundationalism claimsthat there are some basic statements that do not require justification. Both induction and falsification are formsof foundationalism in that they rely on basic statements that derive directly from observations.

The way in which basic statements are derived from observation complicates the problem. Observation is a cognitive act; that is, it relies on our existing

12

understanding, our set of beliefs. An observation of a transit of Venus requires a huge range of auxiliary beliefs, such as those that describe the optics of telescopes, the mechanics of the telescope mount, and an understanding of celestial mechanics. At first sight, theobservation does not appear to be 'basic'.

Coherentism offers an alternative by claiming that statements can be justified by their being a part of a coherent system. In the case of science, the system is usually taken to be the complete set of beliefs of an individual or of the community of scientists. W. V. Quineargued for a Coherentist approach to science. An observation of a transit of Venus is justified by its being coherent with our beliefs about optics, telescope mounts and celestial mechanics. Where this observation isat odds with one of these auxiliary beliefs, an adjustment in the system will be required to remove the contradiction.

Ockham's razor

“ William Ockham (c. 1295–1349) … is remembered as an influential nominalist, but his popular fame as a great logician rests chiefly on the maxim known as Ockham's razor: Entia non sunt multiplicanda praeter necessitatem. No doubt this represents correctly the general tendency of his philosophy, but it has not so far been found in any of his writings. His nearest pronouncement seems to be Numquam ponenda est pluralitas sine necessitate, which occurs in his theologicalwork on the Sentences of Peter Lombard (Super Quattuor Libros Sententiarum (ed. Lugd., 1495), i, dist. 27, qu. 2, K). In his Summa Totius Logicae, i. 12, Ockham citesthe principle of economy, Frustra fit per plura quod potest fieri per pauciora. (Kneale and Kneale, 1962, p. 243) ”

The practice of scientific inquiry typically involves a number of heuristic principles that serve as rules of thumb for guiding the work. Prominent among these are theprinciples of conceptual economy or theoretical parsimonythat are customarily placed under the rubric of Ockham's

13

razor, named after the 14th Century Franciscan friar William of Ockham who is credited with giving the maxim many pithy expressions, not all of which have yet to be found among his extant works. Ockham's razor, however, was not originally a principle of science but of theologyand the issue of parsimony comes, not from science, but from the vow of poverty that was modeled on the life of Christ. However, the origins of the idea do not necessarily take away from its overall usefulness.

The motto is most commonly cited in the form "entities should not be multiplied beyond necessity", generally taken to suggest that the simplest explanation tends to be the correct one. As interpreted in contemporary scientific practice, it advises opting for the simplest theory among a set of competing theories that have a comparable explanatory power, discarding assumptions thatdo not improve the explanation. The "other things being equal" clause is a critical qualification, which rather severely limits the utility of Ockham's razor in real practice, as theorists rarely if ever find themselves presented with competent theories of exactly equal explanatory adequacy.

Among the many difficulties that arise in trying to applyOckham's razor is the problem of formalizing and quantifying the "measure of simplicity" that is implied by the task of deciding which of several theories is the simplest. Although various measures of simplicity have been brought forward as potential candidates from time totime, it is generally recognized that there is no such thing as a theory-independent measure of simplicity. In other words, there appear to be as many different measures of simplicity as there are theories themselves, and the task of choosing between measures of simplicity appears to be every bit as problematic as the job of choosing between theories. Moreover, it is extremely difficult to identify the hypotheses or theories that have "comparable explanatory power", though it may be readily possible to rule out some of the extremes. Ockham's razor also does not say that the simplest account is to be preferred regardless of its capacity to

14

explain outliers, exceptions, or other phenomena in question. The principle of falsifiability requires that any exception that can be reliably reproduced should invalidate the simplest theory, and that the next-simplest account which can actually incorporate the exception as part of the theory should then be preferred to the first. As Albert Einstein puts it, "The supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience".

Social AccountabilityScientific Openness

A very broad issue affecting the neutrality of science concerns the areas over which science chooses to explore,so what part of the world and man is studied by science. Since the areas for science to investigate are theoretically infinite, the issue then arises as to what science should attempt to question or find out.

Philip Kitcher in his "Science, Truth, and Democracy"[6] 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 inthe end to be unscientific.

See also The Mismeasure of Man and Nazi eugenics.

Scientific infallibility

A critical question in the philosophy of science is, to what degree the current body of scientific knowledge can be taken as an indicator of what is actually true about the physical world in which we live? The acceptance of such knowledge as if it were absolutely true and

15

unquestionable (in the sense of theology or ideology) hasbeen called scientism. Claims of scientism ignore a key requirement of the scientific method that all claims be falsifiable and that, given adequate evidence, a scientist must abandon old theories and adopt new ones. In spite of the past record of incremental progress in science (a repeating cycle of widely accepted theoreticalviews being rejected and replaced with new widely accepted theoretical views), scientism envisions no further progress and accepts as correct the body of scientific knowledge as it is currently constituted.

Critiques of scientific method

Paul Feyerabend argued that no description of scientific method could possibly be broad enough to encompass all the approaches and methods used by scientists. Feyerabendobjected to prescriptive scientific method on the groundsthat any such method would stifle and cramp scientific progress. Feyerabend claimed, "the only principle that does not inhibit progress is: anything goes."[7]

Limitations of scienceMany people consider science to be the most powerful human system ever devised for the discovery of truth. Certainly, science has been extremely successful, in the sense that scientific theories underly the operation of all of modern technology. For example, humans could not have devised computers, aviation, telecommunications, civil engineering, or Western medicine without the guidance of science, because all of these fields depend deeply on the basic and particular properties of the physical universe for their operation.

However, there are limitations to what any truth-finding method based on objective replication of experiments can discover. Some fields, such as economics, ecology, or social science can be very hard to experiment with. Even more problematic is the study of human consciousness,

16

which is by nature subjective, yet undeniably "real" in some sense. The human race does not at this time possess reliable techniques to study these and other subjects; better methods of truth-determination for these difficultareas are (or should be) an ongoing project of epistemology, the study of knowledge.

This is why science, though extremely powerful, cannot byitself give rise to a truly complete or balanced worldview. Just as those who do not understand or do not trust science cut themselves off from what may be the largest and most accurate body of knowledge and techniquethat humankind has ever accumulated, anyone who studies only scientific fields denies a huge amount of knowledge, both currently known and potentially knowable.

Sociology and anthropology of scienceIn his book The Structure of Scientific Revolutions Kuhn argues that the process of observation and evaluation take place within a paradigm. 'A paradigm is what the members of a community of scientists share, and, conversely, a scientific community consists of men who share a paradigm' (postscript, part 1). On this account, science can be done only as a part of a community, and is inherently a communal activity.

For Kuhn, the fundamental difference between science and other disciplines is in 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. It is apparent that social factors play an important and direct role in scientific method, but that they do not serve to differentiate science from other disciplines. Furthermore, although on this account science is socially constructed, it does not follow that reality is a social construct. (See Science studies and the links there.) Kuhn’s ideas are equally applicable to both realist and anti-realist ontologies.

17

There are, however, those who maintain that scientific reality is indeed a social construct, to quote Quine:

“ 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, tothe gods of Homer . . . For my part I do, qua lay physicist, believe in physical objects and not in Homer's gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing, the physical objects and the gods differ only in degree and not in kind. Bothsorts of entities enter our conceptions only as cultural posits[8] ”

A major development in recent decades has been the study of the formation, structure, and evolution of scientific communities by sociologists and anthropologists includingMichel Callon, Elihu Gerson, Bruno Latour, John Law, Susan Leigh Star, Anselm Strauss, Lucy Suchman, and others. Some of their work has been previously loosely gathered in actor network theory. Here the approach to the philosophy of science is to study how scientific communities actually operate.

More recently Gibbons and colleagues (1994) have introduced the notion of mode 2 knowledge production.

Researchers in Information science have also made contributions, e.g., the Scientific Community Metaphor.

Continental philosophy of scienceIn the Continental philosophical tradition, science is viewed from a world-historical perspective. One of the first philosophers who supported this view was Georg Wilhelm Friedrich Hegel. Philosophers such as Ernst Mach,Pierre Duhem and Gaston Bachelard also wrote their works with this world-historical approach to science. Nietzsche

18

advanced the thesis in his "The Genealogy of Morals" thatscience was a new form of religion.

All of these approaches involve a historical and sociological turn to science, with a special emphasis on lived experience (a kind of Husserlian "life-world"), rather than a progress-based or anti-historical approach as done in the analytic tradition. Two other approaches to science include Edmund Husserl's phenomenology and Martin Heidegger's hermeneutics.

The largest effect on the continental tradition with respect to science was Martin Heidegger's assault on the theoretical attitude in general which of course includes the scientific attitude. For this reason one could suggest that the philosophy of science, in the Continental tradition, has not developed much further dueto its inability to overcome Heidegger's criticism.

Notwithstanding, there have been a number of important works: especially a Kuhnian precursor, Alexandre Koyré. Another important development was that of 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. His works were considered a great work of art and the science of madnesswas a significant achievement. It involved explaining madness as a science (knowledge) and therefore must be gratified.

Traditional Chinese philosophy of scienceIn ancient China, science and technology were subordinateto value. The formless and personal Tao of Confucianism was holistically mingled with forms and usefulness. Therefore, its philosophy of science and values like moral and pragmatic considerations was a single entity. Together with its holistic health and pacifism, skepticism of the totalitarianism of Taoism also formed part of its characteristics.

19

Philosophy of science by scientistsMany scientists and others who do not consider themselvesphilosophers have commented extensively on the philosophyof science as it relates to their particular discipline. Albert Einstein, for example, wrote a number of popular works that included speculations on the nature of scienceand its relationship to theology. Stephen Jay Gould commented on similar issues regarding biology.

More recently, the battles over teaching evolution and intelligent design in the public schools have brought certain philosophical issues to the fore (most notably, "What makes an area of study scientific?").
