Between Science and Technology
Authors: Agassi Joseph
Published: November 2002

Basic research or fundamental research is distinct from both pure and applied research, in that it is pure research with expected useful results. The existence of basic or fundamental research is problematic, at least for both inductivists and instrumentalists, but also for Popper. Assuming scientific research to be the search for explanatory conjectures and for refutations, and assuming technology to be the search of conjectures and some corroborations, we can easily place basic or fundamental research between science and technology as a part of their overlap. As a bonus, the present view of basic or fundamental research as an overlap explains the specific hardship basic research workers encounter.
Values, Health, and Medicine
Authors: Goosens William K.
Published: November 2002

This paper argues for the importance of approaching medicine, as a theoretical science, through values. The normative concepts of benefit and harm are held to provide a framework for the analysis of medicine which reflects the obligations of the doctor-patient relationship, suffices to define the key concept of medical relevance, yields a general necessary condition for the basic concepts of medicine, explains the role of such nonnormative conceptions as discomfort, dysfunction, and incapacity, and avoids the mistakes of other normative approaches which hold that unhealthy conditions are disvaluable or should be treated. Neutralist analyses are criticized, especially those approaching health through proper functioning.
Why is Mechanics Based on Acceleration?
Authors: Adler Carl G.
Published: November 2002

The unique role of the second derivative of position with respect to time in classical mechanics is investigated. It is indicated that mechanics might have been developed around other order derivatives. Examples based on and are presented. Kirchhoff s argument for using ẍ is given and generalized.
Rational Belief and Probability Kinematics
Authors: van Fraassen Bas C.
Published: November 2002

A general form is proposed for epistemological theories, the relevant factors being: the family of epistemic judgments, the epistemic state, the epistemic commitment (governing change of state), and the family of possible epistemic inputs (deliverances of experience). First a simple theory is examined in which the states are probability functions, and the subject of probability kinematics introduced by Richard Jeffrey is explored. Then a second theory is examined in which the state has as constituents a body of information (rational corpus) and a recipe that determines the accepted epistemic judgments on the basis of this corpus. Through an examination of several approaches to the statistical syllogism, a relation is again established with Jeffrey's generalized conditionalization.
Justification and the Psychology of Human Reasoning
Authors: Stich Stephen P. , Nisbett Richard E.
Published: November 2002

This essay grows out of the conviction that recent work by psychologists studying human reasoning has important implications for a broad range of philosophical issues. To illustrate our thesis we focus on Nelson Goodman's elegant and influential attempt to “dissolve” the problem of induction. In the first section of the paper we sketch Goodman's account of what it is for a rule of inference to be justified. We then marshal empirical evidence indicating that, on Goodman's account of justification, patently invalid inferential rules turn out to be “justified.” We conclude that something is seriously wrong with Goodman's story about justification. In the second section we attempt to patch Goodman's account. The notion of epistemic authority and the social aspect of justification play central roles in the alternative account of justification that we propose.
The Structure of Physical Explanation
Authors: Forge John
Published: November 2002

Some features of physical science relevant for a discussion of physical explanation are mentioned. The D-N account of physical explanation is discussed, and it is seen to restrict the scope of explanation in physical science because it imposes the requirement that the explanandum must be deducible from the explanans. Analysis shows that an alternative view of scientific explanation, called the instance view, allows a wider range of physical explanations. The view is seen to be free from a certain class of counter examples to the D-N theory.
Theory Choice and Resistance to Change
Authors: Lugg Andrew
Published: November 2002

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.
The Trouble with Homunculus Theories
Authors: Margolis Joseph
Published: November 2002

The so-called post-Wittgensteinian Oxford philosophers are often criticized not only for failing to provide for the causal explanation of human behavior and psychological states, but also for failing to recognize that psychological explanations require appeal to sub-personal or molecular processes. Three strategies accommodating this criticism appear in so-called homunculus theories and include: (1) that the sub-systems be assigned intentional or informational content purely heuristically; (2) that the intentional or informational content of molar states be analyzed without remainder in terms of molecular processing; (3) that the entire or salient range of mental or informational molar states be accessible at the molecular level, or vice versa. Option (2) proves to be the most radical and is favored by Dennett. (1) relevantly requires a reduction of the intentional. (3) is illustrated in various ways by the views of Freud, Chomsky, Fodor. (2) is shown to depend on (1) or to be idle; and (3) embraces at least in part an appeal to molar-level explanation. The argument developed attempts to show the sense in which discourse about molar and molecular-level phenomena in the psychological context is fundamentally different from macroscopic and microtheoretical-level discourse about physical phenomena. The conclusion drawn is that neither a molar nor a sub-personal level theory is suitably explanatory in the psychological sense: a psychological theory is committed rather to a set of sub-personal components of such systems, that serve to explain molar phenomena.
Uniqueness and Historical Laws
Authors: Fales Evan
Published: November 2002

This paper presents an argument for the claim that historical events are unique in a nontrivial sense which entails the inapplicability of the Hempelian D-N model to historical explanations. Some previous criticisms of Hempel are shown to be general criticisms of the D-N model which can be outflanked in cases where a reduction to fundamental laws is available. I then survey grounds for denying that explanations by reasons can be effectively reduced to causal explanations, and for rejecting methodological individualism. I conclude with some positive remarks concerning the structure of historical explanations and sense in which historical events are unique.
A Probabilistic Theory of Extensive Measurement
Authors: Falmagne Jean-Claude
Published: November 2002

Algebraic theories for extensive measurement are traditionally framed in terms of a binary relation ≲ and a concatenation (x,y) → xy. For situations in which the data is “noisy,” it is proposed here to consider each expression y ≲ x as symbolizing an event in a probability space. Denoting P(x,y) the probability of such an event, two theories are discussed corresponding to the two representing relations:

Axiomatic analyses are given, and representation theorems are proven in detail.
Discussion: Hypothetico-Deductivism is Hopeless
Authors: Glymour Clark
Published: November 2002

An attractive and apparently indestructible idea about confirmation is that a hypothesis h is confirmed by evidence e if h is a logical consequence of e, or of h and the right sort of other stuff. This idea was advanced in various ways by Ayer (1936), Hempel (1965), Carnap (1959), and still recurs constantly in discussions of confirmation; recently for example, in Schlesinger (1976) and Horwich (1978). The typical modern version of the idea goes like this: a sentence h is confirmed by a sentence e with respect to a theory T if e is true and h & T is consistent and h & T entails e (hereafter, h & T ⊢ e) but T does not entail e (hereafter, T ⊬ e).
Why Gibbs Phase Averages Work—The Role of Ergodic Theory
Authors: Malament David B. , Zabell Sandy L.
Published: November 2002

We propose an “explanation scheme” for why the Gibbs phase average technique in classical equilibrium statistical mechanics works. Our account emphasizes the importance of the Khinchin-Lanford dispersion theorems. We suggest that ergodicity does play a role, but not the one usually assigned to it.
Evolution, Population Thinking, and Essentialism
Authors: Sober Elliott
Published: November 2002

Ernst Mayr has argued that Darwinian theory discredited essentialist modes of thought and replaced them with what he has called “population thinking”. In this paper, I characterize essentialism as embodying a certain conception of how variation in nature is to be explained, and show how this conception was undermined by evolutionary theory. The Darwinian doctrine of evolutionary gradualism makes it impossible to say exactly where one species ends and another begins; such line-drawing problems are often taken to be the decisive reason for thinking that essentialism is untenable. However, according to the view of essentialism I suggest, this familiar objection is not fatal to essentialism. It is rather the essentialist's use of what I call thenatural state modelfor explaining variation which clashes with evolutionary theory. This model implemented the essentialist's requirement that properties of populations be defined in terms of properties of member organisms. Requiring suchconstituent definitionsis reductionistic in spirit; additionally, evolutionary theory shows that such definitions are not available, and, moreover, that they are not needed to legitimize population-level concepts. Population thinking involves the thesis that population concepts may be legitimized by showing their connections witheach other, even when they are not reducible to concepts applying at lower levels of organization. In the paper, I develop these points by describing Aristotle's ideas on the origins of biological variation; they are a classic formulation of the natural state model. I also describe how the development of statistical ideas in the 19th century involved an abandoning of the natural state model.
Probability Kinematics and Representation of Belief Change
Authors: Domotor Zoltan
Published: November 2002

Bayesian, Jeffrey and Field conditionals are compared and it is shown why the last two cannot be reduced to the first. Maximum relative entropy is used in two kinds of justification of the Field conditional and the dispensability of entropy principles in general is discussed.
A Pragmatic Approach to Explanations
Authors: Gärdenfors Peter
Published: November 2002

It is argued that it is not sufficient to consider only the sentences included in the explanans and explanandum when determining whether they constitute an explanation, but these sentences must always be evaluated relative to a knowledge situation. The central criterion on an explanation is that the explanans in a non-trivial way increases the belief value of the explanandum, where the belief value of a sentence is determined from the given knowledge situation. The outlined theory of explanations is applied to some well-known examples and is also compared to other theories of explanation.
On Luce's Theory of Meaningfulness
Authors: Roberts Fred S.
Published: November 2002

This paper studies the theory of uniqueness of scales of measurement, and in particular, the theory of meaningfulness of statements using scales. The paper comments on the general theory of meaningfulness adopted by Luce in connection with his work on dimensionally invariant numerical laws. It comments on Luce's generalization of the concept of meaningfulness of a statement involving scales to a concept of meaningfulness of an arbitrary relation relative to the defining relations in a relational structure. It is argued that in studying the concept of meaningfulness, it is necessary to consider invariance under endomorphisms, not just automorphisms. The difference between the endomorphism and automorphism concepts of meaningfulness is studied. Luce's primary result, that automorphism meaningfulness is preserved under isomorphism, is extended to the result that endomorphism meaningfulness is preserved under homomorphism.
The Role of Normative Assumptions in Historical Explanation
Authors: Currie Gregory
Published: November 2002

This paper concerns the problem of how to give historical explanations of scientist's decisions to prefer one theory over another. It is argued that such explanations ought to contain only statements about the beliefs and preferences of the agents involved, and, in particular, ought not to include evaluative premises about the theories themselves. It is argued that Lakatos's attempt to build into such historical explanations premises of an evaluative kind is deficient. The arguments of Laudan to the effect that such explanations depend crucially upon evaluative assumptions about the rationality or irrationality of decisions are examined. It is argued that they do not establish the need for such assumptions.

Similar criticisms are then shown to be applicable to a version of the ‘hermeneutical’ model of explanation for human actions.
A Limited Conventionalist Critique of Newtonian Space-Time
Authors: Zaret David
Published: November 2002

In this paper, I examine a number of alternative global structures for Newtonian space-time, and corresponding Newtonian theories of mechanics and gravitation. I argue that since these theories differ only with respect to questions concerning the relative distribution of inertial and gravitational forces, the choice between them is a matter of convention. Therefore, the global structure of Newtonian space-time is also a matter of convention. Since this result is based on a consideration of the nature of inertial and gravitational forces, rather than on general reductionist principles, it is a “limited conventionalist” result.
Fixing the Reference of Theoretical Terms
Authors: Nola Robert
Published: November 2002

Kripke and Putnam have proposed that terms may be introduced to refer to theoretical entities by means of causal descriptions such as 'whatever causes observable effects O'. It is argued that such a reference-fixing definition is ill-formed and that theoretical beliefs must be involved in fixing the reference of a theoretical term. Some examples of reference-fixing are discussed e.g., the term 'electricity'. The Kripke-Putnam theory can not give an account of how terms may be introduced into science and then subsequently be discovered to be non-referring. A modified account of reference-fixing is suggested in which terms such as Gilbert's ‘electric effluvia’ and ‘phlogiston’ can be introduced into science and then be found to lack a reference.
Optimal-Design Models and the Strategy of Model Building in Evolutionary Biology
Authors: Beatty John
Published: November 2002

The prevalence of optimality models in the literature of evolutionary biology is testimony to their popularity and importance. Evolutionary biologist R. C. Lewontin, whose criticisms of optimality models are considered here, reflects that “optimality arguments have become extremely popular in the last fifteen years, and at present represent the dominant mode of thought.”

Although optimality models have received little attention in the philosophical literature, these models are very interesting from a philosophical point of view. As will be argued, optimality models are central to evolutionary thought, yet they are not readily accomodated by the traditional view of scientific theories. According to the traditional view, we would expect optimality models to employ general, empirical laws of nature, but they do not. Fortunately, the semantic view of scientific theories, a recent alternative to the traditional view, more readily accomodates optimality models. As we would expect on the semantic view, optimality models can be construed as specifications of ideal systems. These specifications may be used to describe empirical systems—that is, the specifications may have empirical instances. But the specifications are not empirical claims, much less general, empirical laws.

Although philosophers have yet to discuss the general features and uses of optimality models, these topics have stimulated much recent discussion among evolutionary biologists. Their discussions raise a number of precautions concerning the proper use of optimality models. Moreover, many of their caveats can be interpreted as general reminders that 1) optimality models specify ideal systems whose empirical instantiations may be quite restricted, and that 2) optimality models should not be construed as general, empirical laws. As G. F. Oster and E. O. Wilson caution, “the prudent course is to regard optimality models as provisional guides to further empirical research and not necessarily as the key to deeper laws of nature.” It seems, then, that the semantic view of theories is more sensitive to the nature and limitations of optimality models than is the more traditional view of theories.
Strange Expectations
Authors: Hacking Ian
Published: November 2002

A new problem about mathematical expectation: there exists a state of affairs S and options H and T such that in every element of one partition of S, the expectation of H exceeds that of T, while in every element of a different partition of S, the expectation of T exceeds that of H. This problem may be connected with questions about inference in the short and long run, and with questions about confidence intervals and fiducial probability.
Operant Conditioning and Teleology
Authors: Porpora Douglas V.
Published: November 2002

This paper defends the relevance of Taylor's (1964) critique of S-R behaviorism to Skinner's model of operant conditioning. In particular, it is argued against Ringen (1976) that the model of operant conditioning is a nonteleological variety of explanation. Operant conditioning is shown unable, on this account, to provide a parsimonious and predictive explanation of the behavior of higher level organisms. Finally, it is shown that the principle of operant conditioning implicitly assumes a teleological capacity, the admission of which renders the principle of operant conditioning superfluous.
Is There a Dutch Book Argument for Probability Kinematics?
Authors: Armendt Brad
Published: November 2002

Dutch Book arguments have been presented for static belief systems and for belief change by conditionalization. An argument is given here that a rule for belief change which under certain conditions violates probability kinematics will leave the agent open to a Dutch Book.
Induction and Reasoning to the Best Explanation
Authors: Fumerton R. A.
Published: November 2002

In this paper I want to cast doubt on the claim that there is a legitimate process of reasoning to the best explanation which can serve as an alternative to either straightforward inductive reasoning or a combination of inductive and deductive reasoning. I shall argue a) that paradigmatic cases of acceptable arguments to the best explanation must be considered enthymemes and b) that when the suppressed premises are made explicit we have all of the premises we need to present either a straightforward inductive argument or an argument employing both induction and deduction.
Some Problems for “Progress and Its Problems”
Authors: Krips H.
Published: November 2002

In a recent book, Laudan has put forward a new and provocative theory of scientific progress. In this discussion we shall show that some of the claims which Laudan presents as new, are (or at least can be made into) parts of more “traditional” wisdom. In particular (in Section 1) we shall criticize his claim to have uncovered a new class of non-refuting anomalies for theories. We shall also (in section 2) criticize Laudan's view that a theory may have an anomaly because of conflict with non-scientific theories—as long as those theories are perceived of as rational. Laudan's view of theory-assessment—via the assessment of “research traditions”—is also examined in this section. It is found to be a significant departure from both traditional, and more radical (Lakatosian, Kuhnian, Feyerabendian) alternatives. Finally, (in Section 3), we examine Laudan's claim that theories may have anomalies because of conflict with methodological theories.
Minogue on Intensional Reference
Authors: Hesse Mary
Published: November 2002

I am grateful to Brendan Minogue (1978) for his careful and detailed discussion of the concept of “intensional reference” (IR) as it appears in my book The Structure of Scientific Inference (1974). He concludes that my account contains some important inconsistencies that vitiate my attempt to reconcile the idea of cumulative acquisition of scientific knowledge with radically changing theories. He rightly sees that this attempt depends crucially on the account of translatability between theories, and this in turn upon the notion of “identity of intensional reference.” This means that the attempt fails if there are inconsistencies in the concept of IR. Since Minogue's careful analysis nevertheless contains some misunderstandings, I must plead guilty to a number of unclarities, but I do not believe there are basic inconsistencies. Let me try again.
Four Types of Explanation
Authors: Cupples Brian
Published: November 2002

In (Cupples 1977), it was argued that Professor David Kaplan's model of S-explanation could be formulated so as to provide a unified framework for three types of explanation, viz., potential, rationally acceptable, and true. In this note I correct an error in the statement of the conditions for a potential direct S-explanans, show that the corrected version leads to a further simplification in the conditions of the model, and propose a fourth type of explanation which the framework of S-explanation can accommodate.
Turing Machine Arguments
Authors: Nelson R. J.
Published: November 2002

In (Nelson 1976b) I used Turing machine arguments to show that computers can recognize humanly recognizable patterns in principle. In 1978 James D. Heffernan has expressed some doubts about such arguments. He does not question the propositions that I defend in the paper, nor the specific arguments in their support. What he does criticize are certain background assumptions.
On Shames' Experimenter Expectancy Paradox
Authors: Primeaux D.
Published: November 2002

Shames' article (1979) ingeniously attempts to impeach arguments which support the view that a psychologist's experimental results are significantly influenced by the experimenter expectancy effect. This attack is a powerful one in which Shames unveils his “expectancy paradox”: the scientist investigating the influence of the expectancy effect in psychology remains himself subject to any such expectancy effect. Therefore, he argues, “The more substantial is the evidence for the veridicality of experimenter expectancy ... the more suspect it becomes ...” (1979, p. 384). Shames maintains that this paradox is inescapable only if the experimenter expectancy effect is inexorable in any particular research program and is pervasive through the broad spectrum of psychological research. A review of the literature leads him to hold that this effect is neither inexorable nor unquestionably pervasive. “Thus,” Shames concludes, “the expectancy paradox is less pernicious than may have been feared; however, since it is so intimately tied to the experimenter expectancy effect, the spectre of doubt as to the compass of this effect is cast” (1979, p. 387).
A Trivialization of Nagel's Definition of Explanation for Statistical Laws
Authors: Cooke Roger
Published: November 2002

In the theory of explanation it is imperative that self-explanation be excluded; we cannot allow an explanandum to explain itself. This applies to the explanation of events and to the explanation of laws. In Nagel's account the following three features of a valid explanation of a universal law serve as a prophylaxis against self-explanation: “... all the premises are universal statements, there is more than one premise, each of which is essential in the derivation, and the premises, taken singly or conjointly, do not follow logically from the explicandum”).
Jackson and Pargetter on Distant Simultaneity
Authors: Townsend Burke
Published: November 2002

In their article, “Relative Simultaneity in the Special Theory of Relativity,” Jackson and Pargetter (1977) have offered a method to determine distant simultaneity which they claim to be independent of any assumptions concerning one-way velocities and thus a basis for denying the conventionality of distant simultaneity within the framework of the Special Theory. In what follows, I shall argue that the case they make to support the claim to independence is mistaken.
A Confutation of Convergent Realism
Authors: Laudan Larry
Published: November 2002

This essay contains a partial exploration of some key concepts associated with the epistemology of realist philosophies of science. It shows that neither reference nor approximate truth will do the explanatory jobs that realists expect of them. Equally, several widely-held realist theses about the nature of inter-theoretic relations and scientific progress are scrutinized and found wanting. Finally, it is argued that the history of science, far from confirming scientific realism, decisively confutes several extant versions of avowedly ‘naturalistic’ forms of scientific realism.

The positive argument for realism is that it is the only philosophy that doesn't make the success of science a miracle.

Experimental Tests of the Sum Rule
Authors: Redhead M.L.G.
Published: November 2002

Recent discussions of experimental tests of the Sum Rule have been carried out in the context of the special circumstances attending the Cross-Ramsey experiment. A more general analysis of possible tests is presented. A technical mistake of Fine and Glymour concerned with a misunderstanding of the physics of the Cross-Ramsey experiment is explained and a detailed analysis of a thought experiment based on the Einstein-Podolsky-Rosen wave function is given. It is concluded, in agreement with Fine, that scattering experiments do not test the Sum Rule as a principle which supplements standard quantum mechanics.
Causal Explanations in Classical and Statistical Thermodynamics
Authors: Wicken Jeffrey S.
Published: November 2002

This paper considers the problem of causal explanation in classical and statistical thermodynamics. It is argued that the irreversibility of macroscopic processes is explained in both formulations of thermodynamics in a teleological way that appeals to entropic or probabilistic consequences rather than to efficient-causal, antecedental conditions. This explanatory structure of thermodynamics is not taken to imply a teleological orientation to macroscopic processes themselves, but to reflect simply the epistemological limitations of this science, wherein consequences of heat-work asymmetries are either macroscopically measurable (entropy) or calculable (probabilities), while efficient-causal relationships are obscure or indeterminable.
Ambiguities and Pragmatic Factors in the Units of Selection Controversy
Authors: Cassidy John
Published: November 2002

The question “what is (are) the unit(s) of selection” can be interpreted in three different ways. These interpretations are discussed and it is shown that they prompt different answers; such units are shown to be individuals in the context of the given interpretation. One of these interpretations is argued, by examples, not always to have an unambiguously correct answer. An alternative approach to this question is sketched.
Beyond Positivism: A Research Program for Philosophy of History
Authors: Martin Raymond
Published: November 2002

It is argued that the debate over the positivist theory of historical explanation has made only a limited contribution to our understanding of how historians should defend the explanations they propose importantly because both positivists and their critics tacitly accepted two assumptions. The first assumption is that if the positivist analysis of historical explanation is correct, then historians ought to attempt to defend covering laws for each of the explanations they propose. The second is that unless a historian can justify an explanation that he proposes, then his preference for that explanation is not rationally defensible. It is argued that the first assumption is false and that if in order to justify an explanation, one must justify a covering law for it, then the second assumption is also false. A program for investigating how historians should defend their explanations is suggested.
A Note on Quantum Logic and the Uncertainty Principle
Authors: Gibbins Peter
Published: November 2002

It is shown that the uncertainty principle has nothing directly to do with the non-localisability of position and momentum for an individual system on the quantum logical view. The product Δx·Δp for localisation of the ranges of position and momentum of an individual system → ∞, while the quantities ΔX and ΔP in the uncertainty principle ΔX·ΔP ≥ ħ/2, must be given a statistical interpretation on the quantum logical view.
On the Alleged Backwards Referral of Experiences and Its Relevance to the Mind-Body Problem
Authors: Churchland Patricia Smith
Published: November 2002

A remarkable hypothesis has recently been advanced by Libet and promoted by Eccles which claims that there is standardly a backwards referral of conscious experiences in time, and that this constitutes empirical evidence for the failure of identity of brain states and mental states. Libet's neurophysiological data are critically examined and are found insufficient to support the hypothesis. Additionally, it is argued that even if there is a temporal displacement phenomenon to be explained, a neurophysiological explanation is most likely.
The Experimental Evidence for Subjective Referral of a Sensory Experience Backwards in Time: Reply to P. S. Churchland
Authors: Libet Benjamin
Published: November 2002

Evidence that led to the hypothesis of a backwards referral of conscious sensory experiences in time, and the experimental tests of its predictions, is summarized. Criticisms of the data and the conclusion by Churchland that this hypothesis is untenable are analysed and found to be based upon misconceptions and faulty evaluations of facts and theory. Subjective referral in time violates no neurophysiological principles or data and is compatible with the theory of “mental” and “physical” correspondence.
Purpose, Feedback, and Evolution
Authors: Falk Arthur E.
Published: November 2002

This essay develops a theory of natural signs in order to show how evolutionary theory breathes new life into teleology. An argument to the contrary presented by Richard Taylor is refuted. The essay defends the view that the concept of negative feedback explicates purposiveness and that symbiotic evolution explains the occurrence of naturally adapted feedback systems. But evolution itself is not a teleological process, nor is it a negative feedback system. There is an exploration of the nature of the dissatisfaction we feel with an evolutionary account of purposiveness from which the fortuitous cannot be eliminated.
The Problem of Inertia
Authors: Christensen Ferrel
Published: November 2002

Many modern commentators on inertial phenomena hold (or just assume) that there is no “problem of inertia”, on the grounds that either (a) no explanation is needed for such phenomena or (b) the explanation is already at hand. My purpose here is to comment on both views, defending the thesis that the problem is real and still unsolved.
Feasible Inferences
Authors: Cherniak Christopher
Published: November 2002

A philosophically important but largely overlooked cognitive theory is examined, one that provides information on which inferences an agent will make from his beliefs. Such a theory of feasible inferences is indispensable in a complete cognitive psychology, in particular, for predicting the agent's actions on the basis of rationality conditions and attributed beliefs and desires. However, very little of the feasibility theory which applies to a typical human being can be shown a priori to apply to all agents. The logical competence required of a rational agent seems to have a cluster structure: it cannot be the case that an agent is able to make no inferences, but an agent can be unable to make any particular one.
In Defense of the Neyman-Pearson Theory of Confidence Intervals
Authors: Mayo Deborah G.
Published: November 2002

In Philosophical Problems of Statistical Inference, Seidenfeld argues that the Neyman-Pearson (NP) theory of confidence intervals is inadequate for a theory of inductive inference because, for a given situation, the ‘best’ NP confidence interval, [CIλ], sometimes yields intervals which are trivial (i.e., tautologous). I argue that (1) Seidenfeld's criticism of trivial intervals is based upon illegitimately interpreting confidence levels as measures of final precision; (2) for the situation which Seidenfeld considers, the ‘best’ NP confidence interval is not [CIλ] as Seidenfeld suggests, but rather a one-sided interval [CI0]; and since [CI0] never yields trivial intervals, NP theory escapes Seidenfeld's criticism entirely; (3) Seidenfeld's criterion of non-triviality is inadequate, for it leads him to judge an alternative confidence interval, [CIalt.], superior to [CIλ] although [CIalt.] results in counterintuitive inferences. I conclude that Seidenfeld has not shown that the NP theory of confidence intervals is inadequate for a theory of inductive inference.
On After-Trial Properties of Best Neyman-Pearson Confidence Intervals
Authors: Seidenfeld Teddy
Published: November 2002

On pp. 55–58 of Philosophical Problems of Statistical Inference (Seidenfeld 1979), I argue that in light of unsatisfactory after-trial properties of “best” Neyman-Pearson confidence intervals, we can strengthen a traditional criticism of the orthodox N-P theory. The criticism is that, once particular data become available, we see that the pre-trial concern for tests of maximum power (and for their derivative confidence intervals of shortest expected length) may then misrepresent the conclusion of such a test (or interval estimate). Specifically, I offer a statistical example where there exists a Uniformly Most Powerful test (a UMP-test), a test of highest N-P credentials, which generates a system of “best” confidence intervals (the [CIλ] interval system) with exact confidence coefficients. But the [CIλ] intervals have the unsatisfactory feature that, for a recognizable set of outcomes, the interval estimates cover all parameter values consistent with the data, at strictly less than 100% confidence.
Glymour on Confirmation
Authors: Edidin Aron
Published: November 2002

Glymour has developed an account of the confirmation of scientific hypotheses which he advocates as an alternative to the hypothetico-deductive and Bayesian accounts. This account is subject to a counter-example which may be accomodated by a slight modification. So modified it describes an important dimension of confirmation. If the modification of Glymour's account is slightly extended, both the resulting account and the hypothetico-deductive account may be seen as special cases of a Bayesian theory which is immune to Glymour's criticisms.
Information Theory and Redundancy
Authors: Partridge Derek
Published: November 2002

This paper argues that Information Theoretic Redundancy (ITR) is fundamentally a composite concept that has been continually misinterpreted since the very inception of Information Theory.

We view ITR as compounded of true redundancy and partial redundancy. This demarcation of true redundancy illustrates a limiting case phenomenon: the underlying metric (number of alternatives) differs only by degree but the properties of this concept differ in kind from those of partial redundancy.

Several other studies are instanced which also imply the composite nature of ITR. We thus provide broadly based but particular support for earlier generalized suggestions that it is the underlying calculus of Information Theory rather than the ill-named concepts themselves that provides something of a unitary language for the description of phenomena.
What Price Substitutivity? A Note on Probability Theory
Authors: Leblanc Hugues
Published: November 2002

Teddy Seidenfeld recently claimed that Kolmogorov's probability theory transgresses the Substitutivity Law. Underscoring the seriousness of Seidenfeld's charge, the author shows that (Popper's version of) the law, to wit:

If (∀D)(Pr(B,D) = Pr(C,D)), then Pr(A,B) = Pr(A,C),

follows from just

five constraints on Pr of the most elementary and most basic sort.
Jeffrey's Rule of Conditioning
Authors: Shafer Glenn
Published: November 2002

Richard Jeffrey's generalization of Bayes' rule of conditioning follows, within the theory of belief functions, from Dempster's rule of combination and the rule of minimal extension. Both Jeffrey's rule and the theory of belief functions can and should be construed constructively, rather than normatively or descriptively. The theory of belief functions gives a more thorough analysis of how beliefs might be constructed than Jeffrey's rule does. The inadequacy of Bayesian conditioning is much more general than Jeffrey's examples of uncertain perception might suggest. The “parameterα” that Hartry Field has introduced into Jeffrey's rule corresponds to the “weight of evidence” of the theory of belief functions.
John Stuart Mill's Philosophy of Economics
Authors: Hausman Daniel M.
Published: November 2002

John Stuart Mill regards economics as an inexact and separate science which employs a deductive method. This paper analyzes and restates Mill's views and considers whether they help one to understand philosophical peculiarities of contemporary microeconomic theory. The author concludes that it is philosophically enlightening to interpret microeconomics as an inexact and separate science, but that Mill's notion of a deductive method has only a little to contribute.
Natural Necessity and Laws of Nature
Authors: Hochberg Herbert
Published: November 2002

The paper considers recent proposals by Armstrong, Dretske, and Tooley that revive the view that statements of laws of nature are grounded by the existence of higher order facts relating universale. Several objections to such a view are raised and an alternative analysis, recognizing general facts, is considered. Such an alternative is shown to meet a number of the objections raised against the appeal to higher order facts and it is also related to views of Hume and Wittgenstein. Further objections are then raised to all the non-Humean “realist” attempts to provide special facts to ground the laws of nature.
The Nature and Scope of Genetic Epistemology
Authors: Kitchener Richard F.
Published: November 2002

Although the theory of Jean Piaget is correctly characterized as genetic epistemology, its nature and scope remain unclear and controversial. An examination of Piaget's Introduction à l'épistémologie génétique indicates that Piaget relies heavily upon a model of comparative anatomy and, consequently, that genetic epistemology is about both the history of science and individual development. This biological model seems to be the basis for Piaget's view that the history of science can be seen as a (Kantian) history of scientific concepts whereas psychogenetic development is a history of these very same concepts on the individual level. Finally, although there are passages indicating a different interpretation of the scope of genetic epistemology, I give several reasons for preferring the more liberal interpretation.
On the Nature of the Theory of Evolution
Authors: Wassermann Gerhard D.
Published: November 2002

This paper supplements an earlier one (Wassermann 1978b). Its views aim to reinforce those of Lewontin and other prominent evolutionists, but differ significantly from the opinions of some philosophers of science, notably Popper (1957) and Olding (1978). A basic distinction is made between ‘laws’ and ‘theories of mechanisms’. The ‘Theory of Evolution’ is not characterized by laws, but is viewed here as a hypertheory which explains classifiable evolutionary phenomena in terms of subordinate classifiable theories of ‘evolution-specific mechanisms’ (ESMs), each of which could apply to a host of species. Adaptations could result from ESMs that are rooted in molecular complementarities. The status of optimization theories that aim to predict best adapted states of organisms or populations is also discussed.
Atomism and The Illusion of Crisis: The Danger of Applying Kuhnian Categories toCurrentParticle Physics
Authors: Hendrick R. E. , Murphy Anthony
Published: November 2002

This paper responds to a recent claim by Shrader-Frechette that current particle physics, with its essentially atomist paradigm, is in a state of Kuhnian crisis. We respond to Shrader-Frechette's claim in two ways: first, we argue directly against much of the evidence used by Shrader-Frechette as indicators of Kuhnian crisis; second, we question Shrader-Frechette's application of Kuhnian categories to current research in general, pointing out the dangers inherent in such an analysis.
Quantum Logic and the Projection Postulate
Authors: Hellman Geoffrey
Published: November 2002

This paper explores the status of the von Neumann-Lüders state transition rule (the “projection postulate”) within “real-logic” quantum logic. The entire discussion proceeds from a reading of the Lüders rule according to which, although idealized in applying only to “minimally disturbing” measurements, it nevertheless makes empirical claims and is not a purely mathematical theorem. An argument (due to Friedman and Putnam) is examined to the effect that QL has an explanatory advantage over Copenhagen and other interpretations which relativize truth-value assignments to experimental arrangements. Two versions of QL, the lattice-theoretic (LT) and partial-Boolean-algebra (PBA), are considered. It turns out that the projection postulate is intimately connected with the choice of conditional connective for QL. The effect of the projection postulate is obtained with the Sasaki conditional. However, this choice is found to require extra assumptions, on both the LT and PBA versions, which are either just as ad hoc as the projection postulate itself or indefensible from within the real-logic QL framework.
Explanatory Unification
Authors: Kitcher Philip
Published: November 2002

The official model of explanation proposed by the logical empiricists, the covering law model, is subject to familiar objections. The goal of the present paper is to explore an unofficial view of explanation which logical empiricists have sometimes suggested, the view of explanation as unification. I try to show that this view can be developed so as to provide insight into major episodes in the history of science, and that it can overcome some of the most serious difficulties besetting the covering law model.
Direct Inference and Confirmational Conditionalization
Authors: Levi Isaac
Published: November 2002

The article responds to some of the points raised by B. van Fraassen concerning probability kinematics and direct inference within the framework of the approach to the revision of probability judgment proposed by Levi in The Enterprise of Knowledge. In particular, the critical importance of the question of direct inference is emphasized and explained.
The Structure of Mental Disorder
Authors: Muscari Paul G.
Published: November 2002

The present trend towards an atheoretical statistical method of psychiatric classification has prompted many psychiatrists to conceive of “mental disorder”, or for that matter any other psychopathological designation, as an indexical cluster of properties and events more than a distinct psychological impairment. By employing different combinations of inclusion and exclusion criteria, the current American Psychiatric Association's scheme (called DSM-III) hopes to avoid the over-selectivity of more metaphysical systems and thereby provide the clinician with a flexible means of dealing with a wide diversity of cases. In the hope of redirecting future inquiry, the paper will argue: (1) that this recent trend might appear to be clinically beneficial, but in point of fact it is riddled by unsound theoretical conclusions which leave the field without a deeply reaching base for understanding and treating mental disorder, and (2) that, a fortiori, “mental disorder” is best conceived as not a cluster of properties and events, nor a metaphorical reaction to a breakdown in social interpersonal relations, but as a deeply laid condition characterized by the absence of an imaginally integrated system.
Hobbes: Geometrical Objects
Authors: Sacksteder William
Published: November 2002

Hobbes' philosophy of geometry was eccentric to contemporary movements and worsted in specific controversy. But he laid down stipulations defining geometry and its method which might provide a significant and workable alternative “meta-geometry”. Some of these are isolated and reinterpreted here, especially those concerned with describing magnitudes, motions and quantities, and with his use of proportions. Rather than refutation of commentaries and historical rehash, the effort here is to isolate definitive texts and to offer a reinterpretation of their arguments in succinct form showing their coherence and their interdependence with his other philosophic principles.
Causality and Determinism
Authors: Hesslow Germund
Published: November 2002

A previous paper of mine, that criticized Suppes' probabilistic theory of causality, was in turn criticized by Deborah Rosen. This paper is a development of my argument and an answer to Rosen. It is argued that the concept of causation is used in contemporary science in a way that presupposes determinism. It is shown that deterministic assumptions are necessary for inferences from generic to individual causal relations and for various kinds of eliminative arguments.
Approximate Truth and Confirmation
Authors: Schwartz Robert John
Published: November 2002

In this paper I show that Goodman's theory of projectibility, although partly successful, is inadequate since it fails to take into consideration the “approximate” nature of certain scientific hypotheses.
An Unnoticed Flaw in Barker and Achinstein's Solution to Goodman's New Riddle of Induction
Authors: Shirley Edward S.
Published: November 2002

Barker and Achinstein misread Goodman's definitions of ‘grue’ and ‘bleen’. If we stick to Goodman's definition of ‘grue’ as applying “to all things examined before t just in case they are green but to other things just in case they are blue” (my italics), and his parallel definition of ‘bleen’, then Barker and Achinstein's arguments are seen to be irrelevant. The result is to by-pass the question whether Mr. Grue sees things as grue rather than as green while showing that it is possible for human conceptual schemes to employ different sensory terms. These two issues are separate.
