Debates about scientific realism are closely connected to almost everything else in the philosophy of science, for they concern the very nature of scientific knowledge. Scientific realism is a positive epistemic attitude toward the content of our best theories and models, recommending belief in both observable and unobservable aspects of the world described by the sciences. This epistemic attitude has important metaphysical and semantic dimensions, and these various commitments are contested by a number of rival epistemologies of science, known collectively (...) as forms of scientific antirealism. This article explains what scientific realism is, outlines its main variants, considers the most common arguments for and against the position, and contrasts it with its most important antirealist counterparts.

Eliminative materialism is the thesis that our common-sense conception of psychological phenomena constitutes a radically false theory, a theory so fundamentally defective that both the principles and the ontology of that theory will eventually be displaced, rather than smoothly reduced, by completed neuroscience. Our mutual understanding and even our introspection may then be reconstituted within the conceptual framework of completed neuroscience, a theory we may expect to be more powerful by far than the common-sense psychology it displaces, and more substantially (...) integrated within physical science generally. My purpose in this paper is to explore these projections, especially as they bear on (1) the principal elements of common-sense psychology: the propositional attitudes (beliefs, desires, etc.), and (2) the conception of rationality in which these elements figure.

In this paper I develop five worries concerning Cartwright’s realism about entities and capacities. The first is that while she was right to insist on the ontic commitment that flows from causal explanation, she was wrong to tie these commitments solely to the entities that do the causal explaining. This move obscured the nature of causal explanation and its connection to laws. The second worry is that when she turned her attention to causal inference, by insisting on the motto of (...) ‘the most likely cause’, she underplayed her powerful argument for realism. For she focused her attention on an extrinsic feature of causal inference (or, indeed, of any ampliative inference), that is the demand of high probability, leaving behind the intrinsic qualities that causal explanation should have in order to provide the required understanding. The third worry is that her objections to Inference to the Best Explanation were unnecessarily tied to her objections about the falsity of fundamental laws. The fourth worry is that though her argument for positing capacities and being realist about them was supposed to take strength from its parallel with Sellars’s powerful argument for the indispensable explanatory role of positing unobservable entities, there are important disanalogies between the two arguments which cast doubt on the indispensability of capacities. The final (fifth) worry is that laws—perhaps brute regularities—might well have to come back from the front door, since they are still the most plausible candidates for explaining why objects have the capacities to do what they can do.

This paper examines the role of ?situations? in John Dewey's philosophy of logic. To do this properly it is necessary to contrast Dewey's conception of experience and mentality with views characteristic of modern epistemology. The primary difference is that, rather than treat experience as peripheral and or external to mental functions (reason, etc.), we should treat experience as a field in and as a part of which thinking takes place. Experience in this broad sense subsumes theory and fact, hypothesis and (...) evidence, reason and observation, thought and perception. Logic in this view is a formal study of the generic features of all possible kinds of experience in this broad (thick, deep, wide, multifaceted) sense. The goal of this paper is to explain what Dewey thinks a situation is in the context of this view of experience, and to argue for the fundamental importance of that idea for logic and philosophy in general.

In this paper we focus on two claims, put forward by Feyerabend in his later writings , which constitute the metaphysical core of his view of scientific inquiry. The first, that we call the pliability thesis, is the claim that the world can be described by indefinitely many conceptual systems, none of them enjoying a privileged status. The second, that we call the resistance thesis, is the claim that the pliability of the world is limited, i.e., not all the different (...) conceptual systems that can be used to describe the world will be equally successful: the world offers resistance to some attempts to describe it. We show that, in spite of the later Feyerabend’s notorious antirealist leanings, the pliability thesis is fully compatible with a robustly realist view of science, and we suggest that, surprisingly, Feyerabend’s insights concerning the limited pliability of the world turn out to be those of a potential ally of sophisticated versions of scientific realism.

An interpretation of John Dewey’s views about realism, science, and naturalistic philosophy is presented. Dewey should be seen as an unorthodox realist, with respect to both general metaphysical debates about realism and with respect to debates about the aims and achievements of science.

The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...) and anti-realists have been talking past one another. We then formulate a dilemma for advocates of either argument, answer potential objections to our criticism, discuss what remains (if anything) of these two major arguments, and then speculate about a future philosophy of science freed from these two arguments. In so doing, we connect the point about base rates to the wholesale/retail distinction; we believe it hints at an answer of how to distinguish profitable from unprofitable realism debates. In short, we offer a probabilistic analysis of the feeling of ennui afflicting contemporary philosophy of science. (shrink)

At a New York cocktail party shortly after the war, a young and insecure physics postgraduate was heard to blurt out to a woman he had met there: ‘I just want to know what Truth is!’ This was Thomas Kuhn and what he meant was that specific truths such as those of physics mattered less to him than acquiring metaphysical knowledge of the nature of truth. Soon afterwards, he gave up physics, but rather than take up philosophy directly, he approached (...) it by way of the history of science. The work that followed, especially The Structure of Scientific Revolutions , published in 1962 and now with sales of well over a million copies, makes his the most important contribution to the history and philosophy of science of the twentieth century.

This paper explores the influence of the fifth-century Christian Neoplatonist Pseudo-Dionysius the Areopagite (Denys) on the twentieth-century philosopher of science Paul Feyerabend. I argue that the later Feyerabend took from Denys a metaphysical claim—the ‘doctrine of ineffability’—intended to support epistemic pluralism. The paper has five parts. Part one introduces Denys and Feyerabend’s common epistemological concern to deny the possibility of human knowledge of ultimate reality. Part two examines Denys’ arguments for the ‘ineffability’ of God as presented in On the Divine (...) Names . Part three then explores how Feyerabend imported Denys’ account of divine ineffability into his own metaphysics to provide a novel argument for epistemic pluralism. Part four explains the significance of an appreciation of Dionyius’ influence for our understanding of Feyerabend. I conclude that Denys was a significant and neglected influence upon the later Feyerabend. (shrink)

This paper is a critique of ‘integrative medicine’ as an ideal of medical progress on the grounds that it fails to realise the cognitive value of alternative medicine. After a brief account of the cognitive value of alternative medicine, I outline the form of ‘integrative medicine’ defended by the late Stephen Straus, former director of the US National Centre for Complementary and Alternative Medicine. Straus’ account is then considered in the light of Zuzana Parusnikova’s recent criticism of ‘integrative medicine’ and (...) her distinction between ‘cognitive’ and ‘opportunistic’ engagement with alternative medicine. Parusnikova warns that the medical establishment is guilty of ‘dogmatism’ and proposes that one can usefully invoke Karl Popper’s ‘critical rationalism’ as an antidote. Using the example of Straus, I argue that an appeal to Popper is insufficient, on the grounds that ‘integrative medicine’ can class as a form of cognitively-productive, critical engagement. I suggest that Parusnikova’s appeal to Popper should be augmented with Paul Feyerabend’s emphasis upon the role of ‘radical alternatives’ in maximising criticism. ‘Integrative medicine’ fails to maximise criticism because it ‘translates’ alternative medicine into the theories and terminology of allopathic medicine and so erodes its capacity to provide cognitively-valuable ‘radical alternatives’. These claims are then illustrated with a discussion of ‘traditional’ and ‘medical’ acupuncture. I conclude that ‘integrative medicine’ fails to exploit the cognitive value of alternative medicine and so should be rejected as an ideal of medical progress. (shrink)

“Bohr was primarily a philosopher, not a physicist, but he understood that natural philosophy... carries weight only if its every detail can be subjected to the... test of experiment”. As a result his approach differed from that of the school-philosophers whom he regarded with a somewhat “sceptical attitude, to say the least” and whose lack of interest in “the important viewpoint which had emerged during the development of atomic physics” he noticed with regret. But it also differed, and to a (...) considerable degree, from the spirit of what Professor T. S. Kuhn has called a “normal science.” Looking at Bohr's method of research we see that technical problems, however remote, are always related to a philosophical point of view; they are never treated as “tiny puzzles” whose solution is valuable in itself, even if one has not the faintest idea what it means, and where it leads: “For me” Bohr writes to Sommerfeld in 1922 “[the quantum theory] is not a matter for petty didactic details, but a serious attempt to reach... an inner coherence.” Emphasis is put on matters of principle and minor discrepancies, or “puzzles” in the sense of Kuhn, instead of being deemphasized, and assimilated to the older paradigm, are turned into fundamental difficulties by looking at them from a new direction, and by testing their background “in its furthest consequences by exaggeration”. A noteworthy example of Bohr's “non-normal” and rather metaphysical approach to physics is his scepticism in the face of the success of his own atomic model. (shrink)

Discussions of the interpretation of quantum theory are at present obstructed by (1) the increasing axiomania in physics and philosophy which replaces fundamental problems by problems of formulation within a certain preconceived calculus, and (2) the decreasing (since 1927) philosophical interest and sophistication both of professional physicists and of professional philosophers which results in the replacement of subtle positions by crude ones and of dialectical arguments by dogmatic ones. More especially, such discussions are obstructed by the ignorance of both opponents, (...) and also defenders of the Copenhagen point of view, as regards the arguments which once were used in its defence. The publication of Bunge's Quantum Theory and Reality and especially of Popper's contribution to it are taken as an occasion for the restatement of Bohr's position and for the refutation of some quite popular, but surprisingly naive and uninformed objections against it. Bohr's position is distinguished both from the position of Heisenberg and from the vulgarized versions which have become part of the so-called "Copenhagen Interpretation" and whose inarticulateness has been a boon for all those critics who prefer easy victories to a rational debate. Einstein's main counterargument is discussed, and Bohr's refutation restated. The philosophical background and earlier forms of Bohr's views are stated also. Considering that these views are more detailed, better adapted to the facts of the microdomain than any existing alternative it follows that fundamental discussion must first return to them. Their uniqueness is not asserted, however. Here the author still maintains that a hundred shabby flowers are preferable to a single blossom, however exquisite. But a hundred shabby flowers plus an exquisite blossom are more desirable still. (shrink)

Scientific realism has three dimensions: a metaphysical commitment to the existence of a mind-independent world; a semantic commitment to a literal interpretation of scientific claims; and an epistemological commitment to scientific knowledge of both observable and unobservable entities. The semantic dimension is uncontroversial, and the epistemological dimension, though contested, is well articulated in a number of ways. The metaphysical dimension, however, is not even well articulated. In this paper, I elaborate a plausible understanding of mind independence for the realist – (...) plausible in conceding the force of sceptical arguments to the effect that there is no one correct way to carve nature at its joints, but realist in proposing an objective basis for carving nonetheless. Walking this line between implausible realism and full-blown constructivism leads down the path of three forms of relativism or pluralism: one concerning the ways in which scientists “package” properties into entities; another concerning the precise metaphysical natures of these entities; and another concerning the context relativity of their behaviour.

This article agrees with Philip Kitcher that we should aim for a well-ordered science, one that answers the right questions in the right ways. Crucial to this is to address questions of use: Which scientific account is right for which system in which circumstances? This is a difficult question: evidence that may support a scientific claim in one context may not support it in another. Drawing on examples in physics and other sciences, this article argues that work on the warrant (...) of theories in philosophy of science needs to change. Emphasis should move from the warrant of theories in the abstract to questions of evidence for use. (shrink)

How can philosophy of science be of more practical use? One thing we can do is provide practicable advice about how to determine when one empirical claim is relevant to the truth of another; i.e., about evidential relevance. This matters especially for evidence-based policy, where advice is thin—and misleading—about how to tell what counts as evidence for policy effectiveness. This paper argues that good efficacy results (as in randomized controlled trials), which are all the rage now, are only a very (...) small part of the story. To tell what facts are relevant for judging policy effectiveness, we need to construct causal scenarios about will happen when the policy is implemented. (shrink)

This is the first of two papers addressing Browning’s “Designation, Characterization, and Theory in Dewey’s Logic” (2002) where he distinguishes a series of pre-theoretical and theoretical stages for developing a theory of logic. The second of these two papers will recommend a modified version of this scheme of stages of inquiry into inquiry. The present paper recounts Browning’s original version of these stages and the ramifications of not clearly distinguishing them. I respond to Browning’s claim that in Burke 1994 I (...) made two such mistakes of not properly distinguishing theoretical and pre-theoretical stages of inquiry into inquiry. (shrink)

This paper addresses the political constraints on science through a pragmatist critique of Philip Kitcher’s account of “well-ordered science.” A central part of Kitcher’s account is his analysis of the significance of items of scientific research: contextual and purpose-relative scientific significance replaces mere truth as the aim of inquiry. I raise problems for Kitcher’s account and argue for an alternative, drawing on Peirce’s and Dewey’s theories of problem-solving inquiry. I conclude by suggesting some consequences for understanding the proper conduct of (...) science in a democracy. (shrink)

The framework of quantum frames can help unravel some of the interpretive difficulties i the foundation of quantum mechanics. In this paper, I begin by tracing the origins of this concept in Bohr's discussion of quantum theory and his theory of complementarity. Engaging with various interpreters and followers of Bohr, I argue that the correct account of quantum frames must be extended beyond literal space–time reference frames to frames defined by relations between a quantum system and the exosystem or external (...) physical frame, of which measurement contexts are a particularly important example. This approach provides superior solutions to key EPR-type measurement and locality paradoxes. (shrink)

There is sufficient evidence that intellectual property rights are corrupting medical research. One could respond to this from a moral or from an epistemic point of view. I take the latter route. Often in the sciences factual discoveries lead to new methodological norms. Medical research is an example. Surprisingly, the methodological change required will involve political change. Instead of new regulations aimed at controlling the problem, the outright socialization of research seems called for, for the sake of better science. I (...) appeal to an analogy between socialized medicine and socialized research. †To contact the author, please write to: Department of Philosophy, University of Toronto, Toronto, Ontario M5R 2M8, Canada; e‐mail: [email protected].

In recent years, pragmatism in general and John Dewey in particular have been of increasing interest to philosophers of science. Dewey's work provides an interesting alternative package of views to those which derive from the logical empiricists and their critics, on problems of both traditional and more recent vintage. Dewey's work ought to be of special interest to recent philosophers of science committed to the program of analyzing ``science in practice.'' The core of Dewey's philosophy of science is his theory (...) of inquiry---what he called ``logic.'' There is a major lacuna in the literature on this point, however: no contemporary philosophers of science have engaged with Dewey's logical theory, and scholars of Dewey's logic have rarely made connections with philosophy of science. This paper aims to fill this gap, to correct some significant errors in the interpretation of key ideas in Dewey's logical theory, and to show how Dewey's logic provides resources for a philosophy of science.

The paper includes a series of letters exchanged between the author and the late Professor Feyerabend, concerning the best "method" for military intelligence, as a test case for the role of conceptual frameworks in philosophy of science. The letters deal with issues like: Is it possible to make an intelligence estimate without a conceptual framework? Does such a framework have any 'positive' role? If so, how should a conceptual framework in intelligence be built? What risks lurk within it? Is it (...) possible to indicate methods for intelligence estimates which are 'better' and more 'successful' than others? (shrink)

CURRENT CONTROVERSIES about the Mind-Body Identity Theory form a case-study for the investigation of the methods practiced by linguistic philosophers. Recent criticisms of these methods question that philosophers can discern lines of demarcation between "categories" of entities, and thereby diagnose "conceptual confusions" in "reductionist" philosophical theories. Such doubts arise once we see that it is very difficult, and perhaps impossible, to draw a firm line between the "conceptual" and the "empirical," and thus to differentiate between a statement embodying a conceptual (...) confusion and one that expresses a surprising empirical result. The proponent of the Identity Theory are identical with certain brain-processes) holds that his opponents' arguments to the effect that empirical inquiry could not identify brain-processes and sensations are admirable illustrations of this difficulty. For, he argues, the classifications of linguistic expressions that are the ground of his opponents' criticism are classifications of a language which is as it is because it is the language spoken at a given stage of empirical inquiry. But the sort of empirical results that would show brain processes and sensations to be identical would also bring about changes in our ways of speaking. These changes would make these classifications out of date. To argue against the Identity Theory on the basis of the way we talk now is like arguing against an assertion that supernatural phenomena are identical with certain natural phenomena on the basis of the way in which superstitious people talk. There is simply no such thing as a method of classifying linguistic expressions that has results guaranteed to remain intact despite the results of future empirical inquiry. Thus in this area there is no method which will have the sort of magisterial neutrality of which linguistic philosophers fondly dream. (shrink)

The crudest form of materialism will be taken as the basis of argument. If it can successfully evade the objections of some philosophers, then a more refined doctrine will be even less troubled.

I discuss two popular but apparently contradictory theses: -/- T1. The democratic control of science – the aims and activities of science should be subject to public scrutiny via democratic processes of representation and participation. T2. The scientific control of policy, i.e. technocracy – political processes should be problem-solving pursuits determined by the methods and results of science and technology. Many arguments can be given for (T1), both epistemic and moral/political; I will focus on an argument based on the role (...) of non-epistemic values in policy-relevant science. I will argue that we must accept (T2) as a result of an appraisal of the nature of contemporary political problems. Technocratic systems, however, are subject to serious moral and political objections; these difficulties are sufficiently mitigated by (T1). I will set out a framework in which (T1) and (T2) can be consistently and compellingly combined. (shrink)
