Historians tend to speak of the problem of the origin of species or the species question, as if it were a monolithic problem. In reality, the phrase refers to a, historically, surprisingly fluid and pluriform scientific issue. It has, in the course of the past five centuries, been used in no less than ten different ways or contexts. A clear taxonomy of these separate problems is useful or relevant in two ways. It certainly helps to disentangle confusions that have (...) inevitably emerged in the literature in its absence. It may, secondly, also help us to gain a more thorough understanding, or sharper view, of the history of evolutionary thought. A consequent problem-centric look at that history through the lens of various origin of species problems certainly yields intriguing results, including and particularly for our understanding of the genesis of the Wallace–Darwin theory of evolution through natural selection.

In lieu of an abstract, here is a brief excerpt of the content:704 BOOK REVIEWS The Search for the Origins of Christian Worship: Sources and Methods for the Study of Early Liturgy. By PAUL F. BRADSHAW. New York/Oxford: Oxford University Press, 1992. Pp. xi + 217. $35.00 (cloth). Despite broad and general acceptance of the study of liturgy as an academic discipline comprising (among other things) historical, theological, anthropological, aesthetic, and ritual aspects, liturgical scholars themselves are still engaged in refining (...) the contours of this discipline. With regard to historical perspectives on liturgy, for example, contemporary liturgical scholars have both relied upon the ground-breaking work of authors such as Anton Baumstark, Jean Danielou, Gregory Dix, and Josef Jungmann and urged caution in appropriating their insights too facilely or uncritically. More precisely, the kind of research such scholars were able to do on the sources they examined, the editing of new editions of those same sources, the fact of the discovery of additional sources, and the crucial issue of how to interpret what historical sources have to say require that contemporary liturgiologists revisit the early sources of the liturgy ever more carefully and precisely. Paul Bradshaw's contribution in The Search for the Origins of Christian Worship is nothing short of ground-breaking for the contribution it makes to contemporary liturgical method in general and to the study of liturgical sources in particular. With admirable clarity and modesty in tone Bradshaw accomplishes his aim: " to offer a guide or handbook for the journey through the field of liturgical origins" (x). He makes no claim that even a careful study of liturgical origins or liturgical history comprises the discipline and craft of liturgiology. What he does claim and exemplify in this remarkable hook is that the study of the sources of liturgy requires careful contextualization as well as precise textual and source criticism of the documents so that what can he legitimately gleaned from historical investigation continues to be a major factor in liturgical study. Bradshaw published some of the material in this carefully constructed monograph in an article in Studia Liturgica 17 (1987): 26-34 and in his contributions to The Making of Jewish and Christian Worship (1991) and Fountain of Life (1991). Among the author's noteworthy accomplishments is the way he has incorporated this material into a new synthesis here. The first three chapters deal with the Jewish background of Christian worship, worship in the New Testament, and principles for interpreting early Christian liturgical evidence. Bradshaw states and exemplifies one of his chief theses here: that any sense BOOK REVIEWS 705 of a linear progression from Jewish liturgical forms at the time of Jesus through the early Christian centuries is impossible to sustain for at least two reasons. First, the Jewish sources themselves at the time of Christ were not uniform, as exemplified by the fact that some manuscripts presumably attesting to the Jewish practices at the time of Jesus were not compiled until centuries later. And even then the normativity of such texts was not universally held. Second, the pluriformity in church life customarily derived from the scientific study of the scriptures should also be expected to derive from the scientific study of liturgical sources, for example, because of the difference between and evolution within the liturgy both East and West. With regard to what are customarily more precisely termed " liturgical sources " Bradshaw offers significant insights in chapter four about individual documents (e.g., the Didache, the Apostolic Tradition, and the Apostolic Constitutions) and, even more importantly, their interrelationship. The modesty in tone of the whole book is nowhere more evident than when he observes that one needs to be cautious in determining whether these documents describe or prescribe what should be done liturgically and when he muses about why some of the evidence in these texts should have appeared there at all. This caution is sustained in chapter five describing "other major liturgical sources," namely, the apostolic fathers, patristic texts, and the diary of Egeria. Here again the descriptive/prescriptive issue resurfaces especially regarding Justin's accounts of liturgy in his First Apology, insights about initiation rites in patristic homilies and catecheses, and the ceremonies of the Easter triduum recounted by Egeria. In chapters six through eight... (shrink)

Human beings are strange animals. Although evolutionary theory has brilliantly accounted for the features we share with other creatures—from the genetic code that directs the construction of our bodies to the details of how our muscles and neurons work—we still stand out in countless ways. Our brains are exceptionally large, we alone have truly grammatical language, and we alone compose symphonies, drive cars, eat spaghetti with a fork and wonder about the origins of the universe.

The practice of justifying scientific explanations generates argumentative patterns in which several types of arguments may play a role. This paper is aimed at identifying these patterns on the basis of an exploration of the institutional conventions regarding the nature, the shape and the quality of scientific explanations as reflected in the writings of influential philosophers of science. First, a basic pattern for justifying scientific explanations is described. Then, two types of extensions of this pattern are presented. (...) These extensions are derived from philosophical accounts of requirements for the quality of explanations and the choice of the best explanation from a number of candidate explanations respectively. The description of the second extension will make clear how pragmatic argumentation plays a role in argumentative patterns within the scientific domain. (shrink)

Scientific inquiry has led to immense explanatory and technological successes, partly as a result of the pervasiveness of scientific theories. Relativity theory, evolutionary theory, and plate tectonics were, and continue to be, wildly successful families of theories within physics, biology, and geology. Other powerful theory clusters inhabit comparatively recent disciplines such as cognitive science, climate science, molecular biology, microeconomics, and Geographic Information Science (GIS). Effective scientific theories magnify understanding, help supply legitimate explanations, and assist in formulating predictions. (...) Moving from their knowledge-producing representational functions to their interventional roles (Hacking 1983), theories are integral to building technologies used within consumer, industrial, and scientific milieus. -/- This entry explores the structure of scientific theories from the perspective of the Syntactic, Semantic, and Pragmatic Views. Each of these views answers questions such as the following in unique ways. What is the best characterization of the composition and function of scientific theory? How is theory linked with world? Which philosophical tools can and should be employed in describing and reconstructing scientific theory? Is an understanding of practice and application necessary for a comprehension of the core structure of a scientific theory? How are these three views ultimately related? (shrink)

Almost everyone has an intuitive notion of what a random number is. For example, consider these two series of binary digits: 01010101010101010101 01101100110111100010 The first is obviously constructed according to a simple rule; it consists of the number 01 repeated ten times. If one were asked to speculate on how the series might continue, one could predict with considerable confidence that the next two digits would be 0 and 1. Inspection of the second series of digits yields no such comprehensive (...) pattern. There is no obvious rule governing the formation of the number, and there is no rational way to guess the succeeding digits. The arrangement seems haphazard; in other words, the sequence appears to be a random assortment of 0's and 1's. (shrink)

What could be more certain than the fact that 2 plus 2 equals 4? Since the time of the ancient Greeks mathematicians have believed there is little---if anything---as unequivocal as a proved theorem. In fact, mathematical statements that can be proved true have often been regarded as a more solid foundation for a system of thought than any maxim about morals or even physical objects. The 17th-century German mathematician and philosopher Gottfried Wilhelm Leibniz even envisioned a ``calculus'' of reasoning such (...) that all disputes could one day be settled with the words ``Gentlemen, let us compute!'' By the beginning of this century symbolic logic had progressed to such an extent that the German mathematician David Hilbert declared that all mathematical questions are in principle decidable, and he confidently set out to codify once and for all the methods of mathematical reasoning.

An acceptable empiricist account of laws of nature would havesignificant implications for a number of philosophical projects. For example, such an account may vitiate argumentsthat the fundamental constants of nature are divinelydesigned so that laws produce a life permittinguniverse. On an empiricist account, laws do not produce the universe but are designed by us to systematize theevents of a universe which does in fact contain life; so any ``fine tuning'' of natural law has a naturalistic explanation.But there are problems for (...) the empiricist project. This paper develops a ``perspectival'' version of the Humean bestsystem approach and argues that this version solves the standard problems faced by the empiricist project.Furthermore, the paper argues, this version is best able to answer the proponents of divine design while leaving scientificlaw a suitably objective matter.[I]t is possible tocondense the enormous mass of results to a large extent – that is to find laws which summarize...Richard Feynman It has become fashionable in some circles to argue thatscience is ultimately a sham, that we scientists read order into nature, not out of nature, and that the laws of physicsare our laws, not nature's. I believe this is arrant nonsense. You would be hard-pressed to convince a physicist thatNewton's inverse square law of gravitation is a purely cultural concoction. The laws of physics, I submit, reallyexist in the world out there, and the job of the scientist is to uncover them, not invent them. True, at any giventime, the laws you find in the textbooks are tentative and approximate, but they mirror, albeit imperfectly, a reallyexisting order in the physical world. Of course, many scientists do not recognize that in accepting the reality of anorder in nature-the existence of laws `out there' – they are adopting a theological world view. P. C. W. Davies.

A scientific theory is successful, according to Stanford (2000), because it is suficiently observationally similar to its corresponding true theory. The Ptolemaic theory, for example, is successful because it is sufficiently similar to the Copernican theory at the observational level. The suggestion meets the scientific realists' request to explain the success of science without committing to the (approximate) truth of successful scientific theories. I argue that Stanford's proposal has a conceptual flaw. A conceptually sound explanation, I claim, (...) respects the ontological order between properties. A dependent property is to be explained in terms of its underlying property, not the other way around. The applicability of this point goes well beyond the realm of the debate between scientific realists and antirealists. Any philosophers should keep the point in mind when they attempt to give an explanation of a property in their field whatever it may be. (shrink)

In a 1993 paper, I argued that empirical treatments of the epistemologyused by scientists in experimental work are too abstract in practice tocounter relativist efforts to explain the outcome of scientificcontroversies by reference to sociological forces. This was because, atthe rarefied level at which the methodology of scientists is treated byphilosophers, multiple mutually inconsistent instantiations of theprinciples described by philosophers are employed by contestingscientists. These multiple construals change within a scientificcommunity over short time frames, and these different versions ofscientific methodology (...) can determine the outcome of a controversy. Iillustrated with a comparatively detailed analysis of the methodologyused by biologists debating the existence of an entity called thebacterial mesosome between the mid-1950s and the mid-1970s. This 1993piece has drawn several critiques in the philosophical literature. Inthis present piece I respond to these critiques and argue that they failto address the core argument of the original paper, and I reflectfurther on the methodologies of philosophers of science pursuingempirical or `naturalistic' epistemology.

Empirically successful scientific theories are intellectual hurricanes. They flood lowlands set aside for worries about definitions. They carry away philosophical reflections that are less dense than the accumulated scientific findings that give these storms their strength, and they fundamentally reshape the conceptual landscape. The history of scholarship reveals that once an empirically corroborated scientific theory explains and predicts phenomena in some domain noticeably better than the available alternatives (whether those alternatives are scientific theories or not), among (...) experts at least, the process of conceptualizing those phenomena, thereafter, mostly floats along on the surface of debates about the comparative scientific merits of that theory and its competitors. Earlier debates about definitions lose most of their interest until new theories arise that generate new, less easily managed empirical findings in the pertinent domains. Across the centuries, the fates of such concepts as ‘inertia’ and ‘planet’ are fitting illustrations of these patterns, as are, more recently, the fates of such concepts as ‘gene’ and ‘deciding’ (aka “decision making”).

The unpredictability of the development and results of a research program is often invoked in favor of a free, desinterested science that would be led mainly by scientific curiosity, in contrast with a use-inspired science led by definite practical expectations. This paper will challenge a crucial but underexamined assumption in this line of defense of scientific freedom, namely that a free science is the best system of science to generate unexpected results. We will propose conditions favoring the occurrence (...) of unexpected facts in the course of a scientific investigation and then establish that use-inspired science actually scores better in this area.

Modern societies depend on a growing production of scientific knowledge, which is based on the functional differentiation of science into still more specialised scientific disciplines and subdisciplines. This is the basis for the paradox of scientific expertise: The growth of science leads to a fragmentation of scientific expertise. To resolve this paradox, the present paper investigates three hypotheses: 1) All scientific knowledge is perspectival. 2) The perspectival structure of science leads to specific forms of knowledge (...) asymmetries. 3) Such perspectival knowledge asymmetries must be handled through second order perspectives. We substantiate these hypotheses on the basis of a perspectivist philosophy of science grounded in Peircean semiotics and autopoietic systems theory. Perspectival knowledge asymmetries are an unavoidable and necessary part of the growth of scientific knowledge, and more awareness of this fact can help avoid blind and futile struggles between scientific perspectives, and direct efforts toward more appropriate ways of handling these fundamental knowledge asymmetries. Concretely, we show how different kinds of scientific knowledge, expertise, disagreement and learning can be correlated to the perspectival structure of science, and propose how polyocular communication based on observations of the observations made by specialised perspectives can be used to handle such perspectival knowledge asymmetries. This can help overcome the observed problems in carrying out cross-disciplinary research and in the collective use of different kinds of scientific expertise, and thereby make society better able to solve complex, real-world problems.

The scientist's decision of accepting a given proposition is assumed to be dependent on two factors: the scientist's 'private' information about the value of that statement and the proportion of colleagues who also accept it. This interdependence is modelled in an economic fashion, and it is shown that it may lead to multiple equilibria. The main conclusions are that the evolution of scientific knowledge can be path, dependent, that scientific revolutions can be due to very small changes in (...) the empirical evidence, and that not all possible equilibria are necessarily efficient, neither in the economic nor in the epistemic sense. These inefficiencies, however, can be eliminated if scientists can form coalitions. (shrink)

It is often said that knowledge is power, but more often than not relevant knowledge is not used when political decisions are made. This book examines how political decisions relate to scientific knowledge and what factors determine the success of scientific research in influencing policy. The authors take a comparative and historical perspective and refer to well-known theoretical frameworks, but the focus of the book is on three case studies: the discourse of racism, Keynesianism, and climate change. These (...) cases cover a number of countries and different time periods. In all three the authors see a close link between 'knowledge producers' and political decision makers, but show that the effectiveness of the policies varies dramatically. This book will be of interest to scientists, decision makers and scholars alike. (shrink)

A pervasive feature of the sciences, particularly the applied sciences, is an experimental focus on a few (often only one) possible causal connections. At the same time, scientists often advance and apply relatively broad models that incorporate many different causal mechanisms. We are naturally led to ask whether there are normative rules for integrating multiple local experimental conclusions into models covering many additional variables. In this paper, we provide a positive answer to this question by developing several inference rules that (...) use local causal models to place constraints on the integrated model, given quite general assumptions. We also demonstrate the practical value of these rules by applying them to a case study from ecology.
