An argument that the deepest disagreement can on occasion be resolved albeit over time.

The main argument of this paper is that philosophical difficulties regarding scientific discovery arise mainly because philosophers base their arguments on a flawed picture of scientific research. Careful examination of N. R. Hanson's treatment of Kepler's discovery not only puts the rationality of this discovery beyond question, it also reveals what its rationality consists in. We can retrieve the point stressed by Hanson concerning the rational character of discoveries such as Kepler's even as we reject the type of "logical" analysis (...) he proposes. (shrink)

In the first half of the paper, it is argued that while the prospects for a criterion for demarcating scientific theories from pseudoscientific ones are exceedingly dim, it is a mistake to fall back to the position that these differ only with regard to how well they are confirmed. One may admit that different pseudoscientific theories are flawed in different ways yet still insist that their flaws are structural rather than empirical in character. In the second half of the paper, (...) this view is extended to cover the cases of pseudoscientific correlations and therapies, and it is suggested that the pseudosciences are best thought of as radically flawed practices.

Duhem's discussion of physical theories as natural classifications is neither antithetical nor incidental to the main thrust of his philosophy of science. Contrary to what is often supposed, Duhem does not argue that theories are better thought of as economically organizing empirical laws than as providing information concerning the nature of the world. What he is primarily concerned with is the character and justification of the scientific method, not the logical status of theoretical entities. The crucial point to notice is (...) that he took the principle of the autonomy of physics to be of paramount importance and he developed the conception of natural classification in opposition to accounts of physical theories that contravened it.

RÉSUMÉ : Le but de W.V. Quine, dans «Deux dogmes de l’empirisme», n’est pas de prouver contre tous que la distinction analytique/synthétique est intenable ni de fournir une conception originale de la connaissance. Il veut plutôt ébranler l’attrait de l’empiriste pour la distinction et montrer ce en quoi réside un empirisme exempt de dogme. En me concentrant sur §§1-3 et §6, je soutiens que son traitement de l’analyticité est structuré par des hypothèses philosophiques fondamentales et que la conception de la (...) connaissance qu’il défend l’habite depuis fort longtemps. «Deux Dogmes» est moins facilement invalidé quand il est interprété en référence aux premières conférences de Quine sur Carnap.

The purpose of this paper is to draw attention to a pattern of development, the significance of which has not been generally recognized. This pattern is characterized by an initial occurrence of what I shall call an overdetermined problem - i.e. a problem with no solution compatible with accepted belief and practice - followed by a resolution of the problem which relies on and exploits a change in what was previously taken as given.

Summary The argument of this paper is (1) that, contrary to what is often thought, there are cases of disagreement among scientists concerning the relative acceptability of theories which do not turn on nonrational or extra-scientific considerations, (2) that agreement cannot be secured without adversely affecting the scientific enterprise as we know it, and (3) that disagreement can be accommodated within a theory of scientific rationality and progress based on the idea that the relative acceptability of scientific theories is a (...) function of their relative problem-solving effectiveness.The diversity of our opinions does not proceed from some men being more rational than others but solely from the fact that our thoughts pass through diverse channels and the same objects are not considered by all.’ Descartes, Discourse on Method.

Russell (in _Principles of Mathematics_) and Wittgenstein (in _Tractatus Logico-Philosophicus_) largely agree on the twin questions of why pairs of congruent objects cannot always be made to coincide and why surfaces can never be uniformly two colours at once. Both philosophers take space and colour to be mathematically representable, construe the relevant impossibilities as mathematical and hold that mathematical impossibility is at root logical. It is not by chance that Russell says nothing about the phenomena in his Introduction to the (...) _Tractatus_ or surprising that Wittgenstein was unmoved by the objection that his account of colour incompatibility puts paid to his early philosophy.

Study of Wittgenstein's claim in the Preface of the Tractatus that his thoughts are unassailably true and his declaration at the end of the work that his propositions are nonsensical.

There is nothing in Wittgenstein's philosophical writings remotely approaching an unambiguous expression of right-wing or left-wing sentiments. The words "politics" and "political" do not figure in his work and politicians are referred to only in passing. All that can reasonably be argued is that his philosophy has indirect implications for how we should collectively live our lives, approach political problems or think about political theory. In this paper I critically examine claims that have been made regarding the significance of his (...) writings for politics with an eye to showing they are textually dubious or otherwise misleading. (shrink)

Wittgenstein is often portrayed as a radical, even a revolutionary thinker and equally often said to lend aid and comfort to political conservatism. perhaps even as supplying it with a new and more profound rationale. While such interpretations of Wittgenstein are a useful antidote to the widely-held view that he was preoccupied with narrowly academic issues, neither can withstand much scrutiny. A consideration of why not does, however, clarify the general thrust of his thought and its significance for philosophy today.

The object of this paper is twofold: to show that resistance to scientific change on the part of scientists need signal neither irrationality nor the presence of extra-scientific influences; and to show how such resistance can be accommodated within a theory of rational choice. After considerations have been outlined suggesting that scientists cannot rationally resist new scientific theories unless theory choice is subjectivistic (section I), evidence is adduced favoring the contrary view (section II). In section III, a non-subjectivistic, non-relativistic conception (...) of rational choice is proposed which recognizes the possibility of scientists' rationally resisting new scientific developments. Finally, in section IV, some minor misunderstandings concerning resistance are discussed. (shrink)

The problem of colour exclusion is not fatal to Ludwig Wittgenstein’s early philosophy, nor was it the catalyst for his later philosophy. The remarks in the Tractatus about the impossibility of the simultaneous occurrence of two colours at a point in the visual field sit comfortably with the remarks in the rest of the book, the discussion of mathematical physics above all. Furthermore Wittgenstein’s second thoughts about the impossibility were a consequence, not the cause, of the subsequent turn in his (...) philosophy. (shrink)

Science figured in no small way in Wittgenstein’s philosophy, not least in his remarks about representation. Early and late he regarded theories like Newtonian mechanics as means of representing the world rather than as representations.While the notion of a form of representation looms largest in his early writings, it also informs his later remarks. His appropriation of the mathematical physicist’s conception of representation is as fundamental to Remarks on Colour (1950) as to the Tractatus (1918/1922).

§§1–7 of the Investigations should be taken at face value and not read against the grain. Wittgenstein is best understood as saying what he means and meaning what he says, and it is a mistake to suppose the examples of the shopkeeper and builders in §§1–2 cannot be read straightforwardly. The seven sections function as a prologue alerting the reader to the type of problem he intends to tackle and the type of approach he intends to pursue.

Review of David Faust, The Limits of Scientific Reasoning.

A response to Graham Stevens’s response to Lugg, ‘Russell as a Precursor of Quine’ (Bertrand Russell Society Quarterly, nos. 128-129, pp. 9-21). Stevens challenges the argument of this paper that from 1912, if not earlier, Russell was “a naturalistically-minded epistemologist in the Quinean mould”. He maintains that to the contrary “Russell cannot be accurately characterized as an empiricist” and “Russell’s greatest influence on Quine’s naturalistic project did not stem from his epistemology but from his semantics”. In the present note it (...) is argued Stevens overlooks that Russell is in the empiricist camp as well as the naturalist camp and the empiricist elements of Russell’s philosophy are secondary to his naturalism.

On Russell's and Quine's "naturalism".

Philosophical Investigations §§19–20 have received little critical attention and their importance has mostly gone unappreciated. In this paper these sections are examined a few sentences at a time in the order they were written with an eye to determining what Wittgenstein does and does not say and how he has been and can be misinterpreted. In addition it is suggested that the material deserves careful consideration because it sheds light on Wittgenstein’s way of tackling philosophical problems, illuminates his pronouncements about (...) philosophy later in the Investigations, and serves as a valuable antidote to the widely-held view that whenever he discusses a philosophical problem he ends up advancing a philosophical thesis.

Criticism of Larry Laudan's views on disagreement and progress in science.

Although Wittgenstein maintains that there are no theses in philosophy, he is regularly interpreted as advancing or committed to such theses. In this paper I consider a striking case in point, Merrill Ring’s discussion of §19(b), §20(a) and §20(b) of the Philosophical Investigations. I compare Ring's account of the text with Wittgenstein's actual words and stress the importance of refraining from taking Wittgenstein to be engaged in an explanatory or theoretical enterprise.

In diesem Beitrag liefere ich eine Interpretation und Verteidigung der These Thomas Kuhns von der Priorität von Paradigmen. Ich behaupte, daß Kuhns Argument für diese These wichtiger, als gewöhnlich angenommen wird, ist, und zwar sowohl für die Klärung seiner Ideen als auch für die Wissenschaftstheorie im allgemeinen. Anerkennt man seine Kritik an der üblichen Auffassung, daß Regeln den Paradigmen vorausgehen, so erscheint vieles von dem, was er über andere Gegenstände sagt, in einem neuen Licht, und viele Schwierigkeiten, die Philosophen bei (...) ihren Versuchen zur Erklärung des Wissenschaftswandels angetroffen haben, erweisen sich als unbegründet.

Analysis of how intellectual historians and sociologists of science differ.

Putnam argues that reductionism, “the doctrine that the laws of such ‘higher level’ sciences as psychology and sociology are reducible to the laws of lower-level sciences - biology, chemistry, ultimately to the laws of elementary particle physics”, is wrong. In this note, I take issue with some of Putnam’s arguments.

Brief response to Brian Baigrie's "The Justification of Kepler’s Ellipse" (1990).

There is no satisfactory way of distinguishing the parodies of science from the genuine thing. Philosophers tend to think science and pseudoscience differ in kind, but the fact is they differ mostly in degree.

The distinction between saying and showing in Tractatus Logico-Philosophicus is not self-refuting, unbelievable or nonsensical. It makes good sense given Wittgenstein's equation of saying with communicable information and showing with necessarily true thought. The key to understanding his thinking is his claim in the Preface that unassailable and definitive truths are expressed in the book, and the subsidiary assumption that asserting empty truths is nonsensical. His conception of pictures, propositions, logic, mathematics, mathematical physics, mysticism, the inexpressible and solipsism as showing (...) is of a piece with his conception of necessary/a priori truths as tautologies broadly understood. (shrink)

Philosophers concerned with the character of scientific disputes tend to divide into two camps. On the one side there are those who hold that scientists can always settle their differences by appealing to shared assumptions; on the other side there are those who maintain that in many cases scientists must resort to (nonrational ) persuasion to establish their views. The trouble is that for all their strong points both approaches labour under enormous difficulties. Scientific disagreement is often much deeper than (...) the first conception allows while persuasion, propaganda and the like are far less prevalent than the second one requires. On examining scientific practice is becomes clear that philosophers on both sides err in supposing that scientists can resolve their differences in a purely scientific fashion just to the extent that they can single out one of their views on the basis of assumptions that they hold in common. For one thing scientists make progress even though they rarely employ the strategy of reversion to neutral territory. And for another the strategy of reversion to neutral territory is at odds with the important methodological requirement that all relevant information be taken into account. Instead of thinking of scientists as resolving their differences by reviewing their respective positions in the light of their shared assumptions, we should think of them as fashioning positions on which they can agree, as arguing to shared conclusions rather than from shared premises. The relevant picture is one of scientists gradually narrowing the distance that separates them, of their converging on a mutually acceptable viewpoint. Far from being prerequisites for scientists' resolving their disputes, shared assumptions are what result from their managing to resolve them. How scientists who disagree deeply make progress is thus much less of a problem than is usually supposed. What determines whether scientists' conclusions constitute advances is not wether they were obtained by the expedient of reversion to neutral territory but whether each of the available options was fully ventilated. When scientists take into account all the relevant considerations (including those introduced into the discussion by their opponents and those that they can reasonably be expected to know), the question of whether they can be said to have made progress no longer arises. More generally, we misconstrue the manner in which scientists resolve their differences because we allow ourselves to be guided by our philosophical preconceptions about scientific knowledge and we devote insufficient attention to what happens in practice. Instead of exploring how scientists reason to mutually acceptable conclusions, we wrongly assume that they cannot but proceed by reverting to neutral territory. What is needed is not a general account of consensus formation but rather a fresh look at the multitude of ways in which scientists make progress by dint of argument and debate. Considered as a phenomenon in its own right scientific disagreement poses no special problem; it is puzzling only when it is considered within the framework of traditional epistemology. (shrink)

Critical notice of T.W. Adorno et aI., The Positivist Dispute in German Sociology. (Paper has many typographical errors but it is readable.).

I like to say there is no scientific method as such, but rather only the free and utmost use of intelligence.P.W. BridgmanIt is generally believed—see, for example, Lakatos, Dorling, Koertge, Gellner, and Finnocchiaro—that Feyerabend is committed to the view that science is an essentially irrational enterprise. In this paper, I argue initially that this is so only if Feyerabend is saddled with an unreasonable notion of rationality. Next, I point out, first, that there is a reasonable notion of rationality which (...) is compatible with Feyerabend's non-method ‘anything goes’; and, second, that unless coupled with some form of rationalism this non-method is obviously and trivially false. (shrink)

The argument of this paper is that Kuhn's account of rational theory choice is too permissive and that an account that recognizes the large-scale nature of the system of scientific beliefs is more plausible and has more practical force.
