Interpretation, Constraint, and the Prospects of Scientific Realism I explore the interaction between theory-based interpretations of scientific evidence and constraints on theories provided by that evidence. Interpretation is often viewed as a source of error and a reason for scepticism about scientific results. But, I argue, while interpretation does generate epistemic risk, it also points to new sources of evidence that can constrain our theories. This is especially clear in the development of instrumentation that increases the range of our interactions (...) with nature. While the design of such instruments and the interpretation of their outputs are deeply dependent on theory-based interpretations, these outputs can still challenge those very theories. At the same time, theory-guided instrumentation provides us access to aspects of nature that we cannot study with our unaided senses. This access allows us to extend the range of evidence that we collect, and thus increases the constraints on our theories. As a result, theory-guided evidence collection has a positive impact on the prospects of scientific realism since these increasing constraints on our theories provide our only reason for thinking that we may be approaching the development of true theories.

The practice of a priori conceptual analysis requires that the concept being analyzed be available in the analyst's mind. The difficulties of analysis and the existence of disagreements among analysts are explained by distinguishing the implicit knowledge we have of these concepts from the explicit knowledge we seek. This view of disagreement assumes that those who disagree are typically attempting to analyze a single shared concept. In this paper, reasons are developed for replacing this guiding assumption with the alternative assumption (...) that members of a conceptual community often have similar, but not identical, concepts. Adopting this alternative requires that we rethink the nature and aims of conceptual analysis. (shrink)

Creative Intelligence: Essays in the Pragmatic Attitude represents an attempt at intellectual cooperation. No effort has been made, however, to attain unanimity of belief nor to proffer a platform of "planks" on which there is agreement. The consensus represented lies primarily in outlook, in conviction of what is most likely to be fruitful in method of approach. As the title page suggests, the volume presents a unity in attitude rather than a uniformity in results. Consequently each writer is definitively responsible (...) only for his own essay. The reader will note that the Essays endeavor to embody the common attitude in application to specific fields of inquiry which have been historically associated with philosophy rather than as a thing by itself. Beginning with philosophy itself, subsequent contributions discuss its application to logic, to mathematics, to physical science, to psychology, to ethics, to economics, and then again to philosophy itself in conjunction with esthetics and religion. The reader will probably find that the significant points of agreement have to do with the ideas of the genuineness of the future, of intelligence as the organ for determining the quality of that future so far as it can come within human control, and of a courageously inventive individual as the bearer of a creatively employed mind.

This book develops an explanation for the roles of observation and theory in scientific endeavor that occupies the middle ground between empiricism and rationalism, and captures the strengths of both approaches. Brown argues that philosophical theories have the same epistemological status as scientific theories and constructs an epistemological theory that provides an account of the role that theory and instruments play in scientific observation. His theory of perception yields a new analysis of objectivity that combines the traditional view of (...) observation as the foundation of scientific objectivity with the contemporary recognition that observation is theory-dependent.

Professor Brown describes and criticises the major classical model of rationality and offers a new model of this central concept in the history of philosophy and of science.

" --Maurice A. Finocchiaro,Isis "The best and most original aspect of the book is its overall conception.

In recent years empiricism has been under persistent attack, and serious questions have been raised about the ability of empiricism to provide the basis for a viable philosophy of science. The attack has been sufficiently vigorous, and in some quarters sufficiently successful, that many now maintain that empiricism is dead. My aim in this paper is to argue that, rather than being ready for embalmment and emplacement in the museum of philosophic oddities, empiricism is very much alive, and the central (...) thesis of empiricism remains the cornerstone for any viable philosophy of science. This is not to say that the recent attacks on empiricism have been without a point, rather, they have put anyone who would defend empiricism in the position of having to rethink many datails of the empiricist viewpoint. But it is the details, the way in which empiricism has been elaborated by its proponents, not the central empiricist insight, that must be reconsidered. (shrink)

Philosophy of science is still, in the minds of many, identified with positivism. This is understandable since twentieth century philosophy of science originates with the work of the Vienna Circle. Positivism is most famous for the verification theory of meaning, the doctrine that the meaning of any proposition is the method by which it is verified, and that any nonanalytic locution which cannot be proven or disproven by some empirical test has no cognitive significance. Positivism is an attempt to construct (...) a “scientific philosophy” in the worst sense: it is maintained that (with the exception of propositions which are analytic and thus vacuous) only those propositions which occur in the sciences are meaningful, all other discourse having at best some emotive value, but no cognitive content, and all of this is maintained within the confines of an exceedingly narrow notion of scientific knowledge. This notion is so narrow that its advocates found themselves in danger of having to relegate most of physics to the realm of nonsense since physics contains many statements which are strictly universal and thus cannot be conclusively verified.

Scientific theories are analyzed in terms of the role that they play in science rather than in terms of their logical structure. It is maintained that theories: provide descriptions of the fundamental features of their domains; on the basis of 1, explain non-fundamental features of their domains; provide a guide for further research in their domains. Any set of propositions that carries out these functions with respect to some domain counts as a theory. This view of theories is developed and (...) defended, and provides the basis for reconsidering a number of issues in the philisophy of science. It is argued that theories need not be unrestrictedly universal with respect to space and time; that the distinction between observable and theoretical entities fails because observables do function as theoretical entities in scientific theories, that there is no genuine philosophical problem of reduction; that the notion of "levels" can be replaced by the notion of "domains"; and that theories are the basic unit of scientific knowledge.

The novel has always provided a vehicle for commenting on various aspects of human existence. We are familiar with the political novel, the historical novel, or the metaphysical novel, and in this sense Sorrentino's Mulligan Stew, with its running commentary on novels, novelists, critics and publishers, may be viewed as a critical novel. A critical novel, however, has a striking feature which it does not share with the other sorts of novels mentioned above in that a critical novel is itself (...) a novel, and a member of the class of objects on which it is commenting. This is a structure that logicians call “self-reference” and the phenomenon of self-reference has provided a central theme in twentieth century logic and philosophy. (shrink)

“There is, in addition, a second reason for doubting that scientists reject paradigms because confronted with anomalies or counterinstances. In developing it my argument will itself foreshadow another of this essay's main theses. The reasons for doubt sketched above were purely factual; they were, that is, themselves counterinstances to a prevalent epistemological theory. As such, if my present point is correct, they can at best help to create a crisis or, more accurately, to reinforce one that is already very much (...) in existence. By themselves they cannot and will not falsify that philosophical theory, for its defenders will do what we have already seen scientists doing when confronted by anomaly. They will devise numerous articulations and ad hoc modifications of their theory in order to eliminate any apparent conflict. Many of the relevant modifications and qualifications are, in fact, already in the literature. If, therefore, these epistemological counterinstances are to constitute more than a minor irritant, that will be because they help to permit the emergence of a new and different analysis of science within which they are no longer a source of trouble. Furthermore, if a typical pattern, which we shall later observe in scientific revolutions, is applicable here, these anomalies will then no longer seem to be simply facts. From within a new theory of scientific knowledge, they may instead seem very much like tautologies, statements of situations that could not conceivably have been otherwise.”. (shrink)

The thesis that certain competing scientific theories are incommensurable was introduced by Kuhn and Feyerabend in 1962 and has been a subject of widespread critique. Critics have generally taken incommensurable theories to be theories which cannot be compared in a rational manner, but both Kuhn and Feyerabend have explicitly rejected this interpretation, and Feyerabend has discussed ways in which such comparisons can be made in a number of his writings. This paper attempts to clarify the incommensurability thesis through the examination (...) of a number of examples, both scientific and nonscientific, of cases in which incommensurable points of view compete. There follows a discussion of Kuhn's analogy between paradigm change and gestalt shifts, the ways in which incommensurable theories can be compared, and one key reason why the incommensurability thesis has been so often misinterpreted by its critics.

The shortage of organs for transplantation by its nature prompts ethical dilemmas. For example, although there is an imperative to save human life and reduce suffering by maximising the supply of vital organs, there is an equally important obligation to ensure that the process by which we increase the supply respects the rights of all stakeholders. In a relatively unexamined practice in the USA, organs are procured from unrepresented decedents without their express consent. Unrepresented decedents have no known healthcare wishes (...) or advance care planning document; they also lack a surrogate. The Revised Uniform Anatomical Gift Act of 2006 sends a mixed message about the procurement of organs from this patient population and there are hospitals that authorise donation. In addition, in adopting the RUAGA, some states included provisions that clearly allow organ procurement from unrepresented decedents. An important unanswered question is whether this practice meets the canons of ethical permissibility. The current Brief Report presents two principled approaches to the topic as a way of highlighting some of the complexities involved. Concluding remarks offer suggestions for future research and discussion. (shrink)

In his later writings Kuhn reconsidered his earlier account of incommensurability, clarifying some aspects, modifying others, and explicitly rejecting some of his earlier claims. In Kuhn’s new account incommensurability does not pose a problem for the rational evaluation of competing scientific theories, but does pose a problem for certain forms of realism. Kuhn maintains that, because of incommensurability, the notion that science might seek to learn the nature of things as they are in themselves is incoherent. I develop Kuhn’s new (...) account of incommensurability, respond to his anti-realist argument, and sketch a form of realism in which the realist aim is a pursuable goal.Keywords: Incommensurability; Thomas Kuhn; Rationality; Skill; Theory choice; Translation.

A number of philosophers have argued that a naturalized epistemology cannot be normative, and thus that the norms that govern science cannot themselves be established empirically. Three arguments for this conclusion are here developed and then responded to on behalf of naturalized epistemology. The response is developed in three stages. First, if we view human knowers as part of the natural world, then the attempt to establish epistemic norms that are immune to scientific evaluation faces difficulties that are at least (...) as severe as the purported difficulties for naturalized epistemology. Second, some examples of the ways in which norms are proposed and evaluated in the course of scientific research are considered and it is concluded that science has no need for trans?scientific norms. Finally, the three arguments introduced at the outset have no force when they are viewed in the light of the preceding discussion. (shrink)

A major theme of recent philosophy of science has been the rejection of the empiricist thesis that, with the exception of terms which play a purely formal role, the language of science derives its meaning from some, possibly quite indirect, correlation with experience. The alternative that has been proposed is that meaning is internal to each conceptual system, that terms derive their meaning from the role they play in a language, and that something akin to "meaning" flows from conceptual framework (...) to experience. Much contemporary debate on the nature of conceptual change is a direct outgrowth of this holistic view of concepts, and much of the inconclusiveness of that debate derives from the lack of any clear understanding of what a conceptual system is, or of how conceptual systems confer meaning on their terms.

New concepts are constantly being introduced into our thinking. Conceptual Systems explores how these new concepts are entered into our systems along with sufficient continuity with older ideas to ensure understanding. The encyclopaedic breadth of this text highlights the many different aspects and disciplines that together present an insightful view into the various theories of concepts. Harold Brown, a reputable author in the philosophy of science examines several historically influential theories of concepts as well as providing a clear (...) view on the general theory of conceptual change. Interesting case studies examine examples of conceptual change in the history of physics including the move in seventeenth century physics from Galileo to Descates to Newton; and the conceptual framework of the "standard model" in the late twentieth century high- energy physics. The key central themes in the philosophy of science that are explored in- depth in this enormous book make it an essential read for academics in this field. (shrink)

The thesis of this paper is that philosophers are often too hasty in rejecting justifications because the argument that yields the justification is circular. Circularity is distinguished from vicious circularity and several examples are examined in which a proposed justification is circular in a precise sense, but not viciously circular. These include an observational procedure which could yield a velocity in excess of the velocity of light even though the impossibility of such velocities is assumed at a key step in (...) analyzing the data, and an argument that uses a specific argument form to show that that form is invalid.

Recent work in the philosophy of science has taken a decidedly historicist turn. A number of writers have rejected the traditional thesis that science develops through the accumulation of firmly established truths, maintaining instead that scientific research is founded on beliefs which are presupposed without having been proven. Since these presuppositions are not established truths they are subject to revision, and a change in the presuppositions of a discipline results in a fundamental restructuring of that discipline, i.e., a scientific revolution. (...) There are a number of versions of this general approach currently under debate, and there is considerable disagreement on how the various versions are to be interpreted. The central issue of this debate is the nature of scientific revolutions and it will be useful for our purposes to establish a point of reference by sketching an extreme view of scientific revolutions, a view which is often attributed to Kuhn and Feyerabend.

This paper argues that when used judiciously Bayes's law has a role to play in the evaluation of scientific hypotheses. Several examples are presented in which a rational response to evidence requires a judgement whether to apply Bayes's law or whether, for example, to redistribute prior probabilities. The paper concludes that reflection on Bayes's law illustrates how an adequate account of the rational evaluation of hypotheses requires an account of judgement--a point which several philosophers have noted despite few attempts to (...) develop an adequate theory of judgement.

Three major views of the observation?theory relation are now extant: (1) Observation and theory are mutually independent and observation provides the basis for evaluating theories. (2) Observations are theory?dependent and do not provide objective grounds for evaluating theories. (3) The concept of observation should be extended in a way that includes many so?called ?theoretical?entities? among the observables. Analyses of these views set the stage for a new approach that incorporates lessons learned from discussions of earlier accounts. The central idea of (...) this new approach is that empirical testing requires comparison of results arrived at by derivation from the theory being tested (plus appropriate auxiliary premises) with results derived from an interaction with aspects of nature in the theory's domain. These routes are independent in that each can be pursued without knowledge of the details or results of the alternative route. The approach accounts for the role of empirical results in evaluating theories without requiring that these results be theory?free or more certain than theoretical results. It also provides a basis for understanding the conditions under which a conflict between observation and theory can result in rejection of the observational result. (shrink)
