On Rejecting Foss's Image of Van Fraassen
Authors: Bourgeois Warren
Published: November 2002

Foss's critique of van Fraassen's constructive empiricism is shown to be completely wide of the mark (Foss 1984, van Fraassen 1980). Foss misunderstands van Fraassen's use of the terms ‘observable’, ‘phenomena’, ‘empirical adequacy’, and ‘epistemic community’. He misconstrues constructive empiricism as making knowledge, and perhaps existence, dependent on the observer. On the basis of this error, he attempts to reduce constructive empiricism to skepticism. None of his criticisms are to the point.
The Logical Inconsistency of the Old Quantum Theory of Black Body Radiation
Authors: Norton John
Published: November 2002

The old quantum theory of black body radiation was manifestly logically inconsistent. It required the energies of electric resonators to be both quantized and continuous. To show that this manifest inconsistency was inessential to the theory's recovery of the Planck distribution law, I extract a subtheory free of this manifest inconsistency but from which Planck's law still follows.
Competing Units of Selection? A Case of Symbiosis
Authors: Mitchell Sandra D.
Published: November 2002

The controversy regarding the unit of selection is fundamentally a dispute about what is the correct causal structure of the process of evolution by natural selection and its ontological commitments. By characterizing the process as consisting of two essential steps—interaction and transmission—a singular answer to the unit question becomes ambiguous. With such an account on hand, two recent defenses of competing units of selection are considered. Richard Dawkins maintains that the gene is the appropriate unit of selection and Robert Brandon, in response, argues that the individual organism is better suited to the role. This paper argues that by making explicit the underlying questions that each of these views addresses, the apparent conflict can be resolved. Furthermore, such a resolution allows for a more complete and realistic understanding of the process of evolution by natural selection.
Husserl's Later Philosophy of Natural Science
Authors: Heelan Patrick A.
Published: November 2002

Husserl argues in the Crisis that the prevalent tradition of positive science in his time had a philosophical core, called by him “Galilean science”, that mistook the quest for objective theory with the quest for truth. Husserl is here referring to Göttingen science of the Golden Years. For Husserl, theory “grows“ out of the “soil” of the prescientific, that is, pretheoretical, life-world. Scientific truth finally is to be sought not in theory but rather in the pragmatic-perceptual praxes of measurement. Husserl is faulted for taking measuring processes to be “infinitely perfectible“. The dependence of new scientific phenomena on the existence of prior “prescientific” inductive praxis is analyzed, also Husserl's residual objectivism and failure to appreciate the hermeneutic character of measurement. Though not a scientific (theory-)realist, neither was he an instrumentalist, but he was a scientific (phenomena-)realist.
Machine Models for Cognitive Science
Authors: Nelson R. J.
Published: November 2002

Introduction. During the past two decades philosophers of psychology have considered a large variety of computational models for philosophy of mind and more recently for cognitive science. Among the suggested models are computer programs, Turing machines, pushdown automata, linear bounded automata, finite state automata and sequential machines. Many philosophers have found finite state automata models to be the most appealing, for various reasons, although there has been no shortage of defenders of programs and Turing machines. A paper by Arthur Burks (1973) convinced me long ago that “all natural human functions” are, or can be fruitfully modeled to be, finite state automata with output. Further work in the field has reinforced this conviction. There is room, however, for the use of any of the above models in philosophy of mind and in the ongoing development of cognitive science.
Scientific Discovery and Maxwell's Kinetic Theory
Authors: Achinstein Peter
Published: November 2002

By reference to Maxwell's kinetic theory, one feature of hypothetico-deductivism is defended. A scientist need make no inference to a hypothesis when he first proposes it. He may have no reason at all for thinking it is true. Yet it may be worth considering. In developing his kinetic theory there were central assumptions Maxwell made (for example, that molecules are spherical, that they exert contact forces, and that their motion is linear) that he had no reason to believe true. In this paper I develop a position that explains why they were worth considering, and that rejects the retroductive position that a hypothesis is worth considering when, if true, it would explain the observed data.
The Logic of Discovery
Authors: Kelly Kevin T.
Published: November 2002

There is renewed interest in the logic of discovery as well as in the position that there is no reason for philosophers to bother with it. This essay shows that the traditional, philosophical arguments for the latter position are bankrupt. Moreover, no interesting defense of the philosophical irrelevance or impossibility of the logic of discovery can be formulated or defended in isolation from computation-theoretic considerations.
Relevance Logic Brings Hope to Hypothetico-Deductivism
Authors: Waters C. Kenneth
Published: November 2002

Clark Glymour has argued that hypothetico-deductivism, which many take to be an important method of scientific confirmation, is hopeless because it cannot be reconstructed in classical logic. Such reconstructions, as Glymour points out, fail to uphold the condition of relevance between theory and evidence. I argue that the source of the irrelevant confirmations licensed by these reconstructions lies not with hypothetico-deductivism itself, but with the classical logic in which it is typically reconstructed. I present a new reconstruction of hypothetico-deductivism in relevance logic that does maintain the condition of relevance between theory and evidence. Hence, if hypothetico-deductivism is an important rationale in science, we have good reason to believe that the logic underlying scientific discourse is captured better by relevance logic than by its classical counterpart.
Parsimony, Likelihood, and the Principle of the Common Cause
Authors: Sober Elliott
Published: November 2002

The likelihood justification of cladistic parsimony suggested in Sober (1984) is here shown to be incomplete. Even so, cladistic parsimony remains a counterexample to the principle of the common cause formulated by Reichenbach (1956) and Salmon (1975, 1979, 1984).
Causal Modeling: New Directions for Statistical Explanation
Authors: Irzik Gurol , Meyer Eric
Published: November 2002

Causal modeling methods such as path analysis, used in the social and natural sciences, are also highly relevant to philosophical problems of probabilistic causation and statistical explanation. We show how these methods can be effectively used (1) to improve and extend Salmon's S-R basis for statistical explanation, and (2) to repair Cartwright's resolution of Simpson's paradox, clarifying the relationship between statistical and causal claims.
Models of Group Selection
Authors: Mayo Deborah G. , Gilinsky Norman L.
Published: November 2002

The key problem in the controversy over group selection is that of defining a criterion of group selection that identifies a distinct causal process that is irreducible to the causal process of individual selection. We aim to clarify this problem and to formulate an adequate model of irreducible group selection. We distinguish two types of group selection models, labeling them type I and type II models. Type I models are invoked to explain differences among groups in their respective rates of production of contained individuals. Type II models are invoked to explain differences among groups in their respective rates of production of distinct new groups. Taking Elliott Sober's model as an exemplar, we argue that although type I models have some biological importance—they force biologists to consider the role of group properties in influencing the fitness of organisms—they fail to identify a distinct group-level causal selection process. Type II models if properly framed, however, do identify a group-level causal selection process that is not reducible to individual selection. We propose such a type II model and apply it to some of the major candidates for group selection.
Horwich on ‘Semantic’ and ‘Metaphysical’ Realism
Authors: Davies David
Published: November 2002

Horwich argues that we should reject metaphysical realism, but that we can preserve semantic realism by adhering to a redundancy theory of truth and a confirmationist account of linguistic understanding. But the latter will give us semantic realism only if it allows that the truth-values of sentences may transcend our recognitional capacities, and this is possible only insofar as we covertly reintroduce metaphysical realism. In spite of its intuitive appeal, we should not endorse semantic realism, but this need not bear upon the tenability ofscientificrealism.
Epr, Bell, and Collapse: A Route Around “Stochastic” Hidden Variables
Authors: Hellman Geoffrey
Published: November 2002

Two EPR arguments are reviewed, for their own sake, and for the purpose of clarifying the status of “stochastic“ hidden variables. The first is a streamlined version of the EPR argument for the incompleteness of quantum mechanics. The role of an anti-instrumentalist (“realist”) interpretation of certain probability statements is emphasized. The second traces out one horn of a central foundational dilemma, the collapse dilemma; complex modal reasoning, similar to the original EPR, is used to derive determinateness (of all spin components of two spin-½ particles in the singlet state) from just (a form of) weak locality, result definiteness, and an assumption on propensities based on conservation. Theories meeting these conditions are therefore constrained by the Bell inequalities. Neither controversial assumptions of “strong locality” (“factorability”) nor of determinism are employed in the derivation. The categories of “stochastic hidden variables” are then analyzed; one can focus on “quasi-definite” theories, without loss of generality. A means of excluding these is proposed, based on a demand that certain ideal cases be accurately treated. Theorems from quantum measurement theory, sometimes cited as showing that such cases are not physically possible, are found inapplicable.
A Quantum-Mechanical Automaton
Authors: Albert David Z.
Published: November 2002

A Quantum-Mechanical automaton, equipped with mechanisms for the measurement and the recording and the prediction of certain physical properties of the world, is described. It is inquired what sort of empirical description such an automaton would produce of itself. It turns out that this description would be a very novel one, one such as was never imagined in the conventional discussions of measurement.
Indefinite Probability Judgment: A Reply to Levi
Authors: Jeffrey Richard
Published: November 2002

Isaac Levi and I have different views of probability and decision making. Here, without addressing the merits, I will try to answer some questions recently asked by Levi (1985) about what my view is, and how it relates to his.
Comments on “Randomization and the Design of Experiments” by P. Urbach
Authors: Mayo O.
Published: November 2002

Urbach (1985) has concluded that the use of randomization in the design of clinical and agricultural trials is both inappropriate and ineffective. It is argued here that it is appropriate, as it eliminates the dependence of inference on the unknown precise physical model that underlies a set of observations, and effective, in that it is relatively simple to apply in practice compared with any competing method. Furthermore, it has been proven in practice.
Wesley Salmon's Scientific Explanation and the Causal Structure of the World
Authors: Fetzer James H.
Published: November 2002

If the decades of the forties through the sixties were dominated by discussion of Hempel's “covering law“ explication of explanation (and its variants), that of the seventies was preoccupied with Salmon's “statistical relevance” conception, which emerged as the principal alternative to Hempel's enormously influential account. Readers of Wesley C. Salmon's Scientific Explanation and the Causal Structure of the World (Salmon 1984), therefore, ought to find it refreshing to discover that its author has not remained content with a facile defense of his previous investigations; on the contrary, Salmon offers an original account of different kinds of explications, advances additional criticisms of various alternative theories, and elaborates a novel “two-tiered“ analysis of explanation that tacitly depends upon a “two-tiered” account of homogeneity. Indeed, if the considerations that follow are correct, Salmon has not merely refined his statistical relevance account but has actually abandoned it in favor of a “causal/mechanistic“ construction. This striking development suggests that the theory of explanation is likely to remain as lively an arena of debate in the eighties as it has been in the past.
Marr's Computational Theory of Vision
Authors: Kitcher Patricia
Published: November 2002

David Marr's theory of vision has been widely cited by philosophers and psychologists. I have three projects in this paper. First, I try to offer a perspicuous characterization of Marr's theory. Next, I consider the implications of Marr's work for some currently popular philosophies of psychology, specifically, the “hegemony of neurophysiology view”, the theories of Jerry Fodor, Daniel Dennett, and Stephen Stich, and the view that perception is permeated by belief. In the last section, I consider what the phenomenon of vision must be like for Marr's project to succeed.
On the Incommensurability of Theories
Authors: Hintikka Jaakko
Published: November 2002

The commensurability of two theories can be defined (relative to a given set of questions) as the ratio of the total information of their shared answers to the total information of the answers yielded by the two theories combined. Answers should be understood here as model consequences (in the sense of the author's earlier papers), not deductive consequences. This definition is relative to a given model of the joint language of the theories, but can be generalized to sets of models. It turns out to capture also the idea of incommensurability as conceptual alienation. Incommensurability so defined does not imply incomparability.
The Uncaused Beginning of the Universe
Authors: Smith Quentin
Published: November 2002

There is sufficient evidence at present to justify the belief that the universe began to exist without being caused to do so. This evidence includes the Hawking-Penrose singularity theorems that are based on Einstein's General Theory of Relativity, and the recently introduced Quantum Cosmological Models of the early universe. The singularity theorems lead to an explication of the beginning of the universe that involves the notion of a Big Bang singularity, and the Quantum Cosmological Models represent the beginning largely in terms of the notion of a vacuum fluctuation. Theories that represent the universe as infinitely old or as caused to begin are shown to be at odds with or at least unsupported by these and other current cosmological notions.
Zeno's Metrical Paradox Revisited
Authors: Sherry David M.
Published: November 2002

Professor Grünbaum's much-discussed refutation of Zeno's metrical paradox turns out to be ad hoc upon close examination of the relevant portion of measure theory. Although the modern theory of measure is able to defuse Zeno's reasoning, it is not capable of refuting Zeno in the sense of showing his error. I explain why the paradox is not refutable and argue that it is consequently more than a mere sophism.
Some PunctuationistsareWrong About the Modern Synthesis
Authors: Thompson Paul
Published: November 2002

Benton Stidd has defended the position that punctuationists are not wrong about the inadequacy of the synthetic theory of evolution for explaining evolution. The thrust of his defense is that arguments to the contrary by Thompson (1983a) involve a rational reconstruction along logical empiricist lines, which is insensitive to historical and social forces in a way that the KuhnianWeltanschauungview that he espouses is not. I argue in this paper that Stidd has entirely misunderstood my arguments, that the soundness of my arguments does not depend on acceptance of logical empiricism (they are just as sound on a Kuhnian view), and that Stidd fails to establish that punctuated equilibria is a new “paradigm“.
Galileo, Rationality and Explanation
Authors: Pitt Joseph C.
Published: November 2002

It is argued that Galileo's theory of justification was a version of explanationism. Galileo's Dialogue on the Two Chief World Systems is to be read as primarily a defense of his theory of the tides. He shows how, by assuming Copernican motions, he can explain the tides, thereby justifying the endorsement of Copernicus. The crux of the argument rests on Galileo's account of explanation, which is novel in its reliance on the use of geometry. Finally, the consequences of his use of geometry, and his views on the limits of knowledge, force us to conclude that if Galileo was a realist, his realism was so highly constrained as to be irrelevant.
The Philosophical Requirements for an Adequate Conception of Scientific Rationality
Authors: Doppelt Gerald
Published: November 2002

I argue that post-Kuhnian approaches to rational scientific change fail to appreciate several distinct philosophical requirements and relativist challenges that have been assumed to be, and may in fact be essential to any adequate conception of scientific rationality. These separate requirements and relativist challenges are clearly distinguished and motivated. My argument then focuses on Shapere's view that there are typically good reasons for scientific change. I argue: (1) that contrary to his central aim, his account of good reasons ultimately presupposes the requirement of universal standards of scientific reasoning; (2) that the good reasons established by his account underdetermine the rationality of scientific change and allow that other changes would have been equally or even more rational; (3) that as a result, Shapere's approach fails to meet what I characterize as the challenges of moderate, sociological, and cognitive relativism.
Discussion: Doppelt Crossed
Authors: Shapere Dudley
Published: November 2002

The chief objections raised by Doppelt (this issue, “The Philosophical Requirements for an Adequate Conception of Scientific Rationality“) against my views fall into three groups: ones having to do with my concept of “success” (that I have provided no analysis of it, and that therefore my concept of “reason“ in science is likewise unexplained; that it requires appeal to some universal criterion); ones having to do with the role of standards or criteria in science (how they are related to substantive beliefs; the possibility of rejecting them); and ones purporting to show that I have not escaped relativism (underdetermination of beliefs; problem of loss in scientific change). I reply to each of these groups of criticisms in turn, concluding with some remarks on the status and validity of the requirements he lays down for any account of scientific rationality.
Perceptual Plasticity and Theoretical Neutrality: A Reply to Jerry Fodor
Authors: Churchland Paul M.
Published: November 2002

The doctrine that the character of our perceptual knowledge is plastic, and can vary substantially with the theories embraced by the perceiver, has been criticized in a recent paper by Fodor. His arguments are based on certain experimental facts and theoretical approaches in cognitive psychology. My aim in this paper is threefold: (1) to show that Fodor's views on the impenetrability of perceptual processing do not secure a theory-neutral foundation for knowledge; (2) to show that his views on impenetrability are almost certainly false; and (3) to provide some additional arguments for, and illustrations of, the theoretical character of all observation judgments.
A Reply to Churchland's “Perceptual Plasticity and Theoretical Neutrality”
Authors: Fodor Jerry A.
Published: November 2002

Churchland's paper “Perceptual Plasticity and Theoretical Neutrality“ offers empirical, semantical and epistemological arguments intended to show that the cognitive impenetrability of perception “does not establish a theory-neutral foundation for knowledge” and that the psychological account of perceptual encapsulation that I set forth in The Modularity of Mind “[is] almost certainly false“. The present paper considers these arguments in detail and dismisses them.
Must Reasons be Rational?
Authors: Levin Janet
Published: November 2002

This paper challenges some leading views about the conditions under which the ascription of beliefs and desires can make sense of, or provide reasons for, a creature's behavior. I argue that it is unnecessary for behavior to proceed from beliefs and desires according to the principles of logic and decision theory, or even from principles that generally get things right. I also deny that it is necessary for behavior to proceed from principles that, though perhaps subrational, are similar to those that we ourselves use. I then propose some conditions that are considerably weaker, and argue that they fulfill the descriptive and explanatory requirements of intentional ascription.
Rationality, Reliability, and Natural Selection
Authors: Feldman Richard
Published: November 2002

A tempting argument for human rationality goes like this: it is more conducive to survival to have true beliefs than false beliefs, so it is more conducive to survival to use reliable belief-forming strategies than unreliable ones. But reliable strategies are rational strategies, so there is a selective advantage to using rational strategies. Since we have evolved, we must use rational strategies. In this paper I argue that some criticisms of this argument offered by Stephen Stich fail because they rely on unsubstantiated interpretations of some results from experimental psychology. I raise two objections to the argument: (i) even if it is advantageous to use rational strategies, it does not follow that we actually use them; and (ii) natural selection need not favor only or even primarily reliable belief-forming strategies.
Systematics and the Darwinian Revolution
Authors: de Queiroz Kevin
Published: November 2002

Taxonomies of living things and the methods used to produce them changed little with the institutionalization of evolutionary thinking in biology. Instead, the relationships expressed in existing taxonomies were merely reinterpreted as the result of evolution, and evolutionary concepts were developed to justify existing methods. I argue that the delay of the Darwinian Revolution in biological taxonomy has resulted partly from a failure to distinguish between two fundamentally different ways of ordering identified by Griffiths (1974): classification and systematization. Classification consists of ordering entities into classes, groups defined by the attributes of their members; in contrast, systematization consists of ordering entities into systems, more inclusive entities whose existence depends on some natural process through which their parts are related. Evolutionary, or phylogenetic, systematics takes evolutionary descent to be the natural process of interest in biological taxonomy. I outline a general framework for a truly phylogenetic systematics and examine some of its consequences.
Explaining Confirmation Practice
Authors: Wylie Alison
Published: November 2002

The contributions to Testing Scientific Theories are unified by an interest in responding to criticisms directed by Glymour against existing models of confirmation–-chiefly H-D and Bayesian schemas–-and in assessing and correcting the “bootstrap“ model of confirmation that he proposed as an alternative in Theory and Evidence (1980). As such, they provide a representative sample of objections to Glymour's model and of the wide range of new initiatives in thinking about scientific confirmation that it has influenced. The effect is a sense of engagement and focus, and of significant advance at least in articulation of the problems that require solution; as Earman observes, “it is … heartening to report that the various opposing camps learned from each other” (p. vi). In what follows I am concerned to assess what has been learned both critically, about Glymour's model, and constructively about the resources of the alternatives he challenges. My thesis is that while the theories emerging in this debate do deal with a wider range of scientific practice than before, their remaining limitations raise important questions about the ambitions and criteria of adequacy that have traditionally governed philosophical inquiry in this area.
Species and Identity
Authors: Splitter Laurance J.
Published: November 2002

The purpose of this paper is to test the contemporary concept ofbiological speciesagainst some of the problems caused by treating species as spatiotemporally extended entities governed by criteria of persistence, identity, etc. After outlining the general problem of symmetric division in natural objects, I set out some useful distinctions (section 1) and confirm that species are not natural kinds (section 2). Section 3 takes up the separate issue of species definition, focusing on the Biological Species Concept (BSC). Sections 4 and 5 examine the matter of species identity over space and time respectively, as determined by the BSC. Both gradualistic and punctuated equilibrium models of speciation are discussed. In section 6 I argue that the BSC fails to determine adequate criteria for dealing with certain kinds of speciation. Section 7 moves speculatively beyond the BSC to a brief examination of alternatives.
The Concept of Measurement and Time Symmetry in Quantum Mechanics
Authors: Bitbol M.
Published: November 2002

The formal time symmetry of the quantum measurement process is extensively discussed. Then, the origin of the alleged association between a fixed temporal direction and quantum measurements is investigated. It is shown that some features of such an association might arise from epistemological rather than purely physical assumptions. In particular, it is brought out that a sequence of statements bearing on quantum measurements may display intrinsic asymmetric properties, irrespective of the location of corresponding measurements in time t of the Schrödinger equation. The situation of an observer performing two measurements in two opposite directions of t is eventually investigated. Essential differences are found between two descriptions of this situation: the internal one (taking only into account what is recorded in the observer's memory) and the external one (whereby the observer is considered as a quantum system ruled by the Schrödinger equation). Finally, a method allowing several observers to establish a correspondence between their memory sizes is analyzed. The most important facts that usually lead to the associating of a preferential temporal direction with quantum measurements may be inferred from this correspondence.
Syntax, Semantics, and the Problem of the Identity of Mathematical Objects
Authors: Rota Gian-Carlo , Sharp David H. , Sokolowski Robert
Published: November 2002

A plurality of axiomatic systems can be interpreted as referring to one and the same mathematical object. In this paper we examine the relationship between axiomatic systems and their models, the relationships among the various axiomatic systems that refer to the same model, and the role of an intelligent user of an axiomatic system. We ask whether these relationships and this role can themselves be formalized.
Do the Bell Inequalities Require the Existence of Joint Probability Distributions?
Authors: Svetlichny George , Redhead Michael , Brown Harvey , Butterfield Jeremy
Published: November 2002

Fine has recently proved the surprising result that satisfaction of the Bell inequality in a Clauser-Horne experiment implies the existence of joint probabilities for pairs of noncommuting observables in the experiment. In this paper we show that if probabilities are interpreted in the von Mises-Church sense of relative frequencies on random sequences, a proof of the Bell inequality is nonetheless possible in which such joint probabilities are assumed not to exist. We also argue that Fine's theorem and related results do not impugn the common view that local realists are committed to the Bell inequality.
Components of Probabilistic Support: The Two-Proposition Case
Authors: Landsberg P. T. , Wise J.
Published: November 2002

Support functions s(h,e) = p(h|e) – p(h) are widely used in discussion of explanation, causality and, recently, in connection with the possibility or otherwise of probabilistic induction. With this latter application in view, a rather complete analysis of the variety of support functions, their interrelationships and their “non-deductive” and “inductive” components is presented. With the restriction to two propositions, three variable probabilities are enough to discuss such problems. The analysis is illustrated by graphs, a Venn diagram and by using the Laplace Rule of Succession as an illustrative example. It is concluded that within this framework one cannot prove or disprove the possibility of probabilistic induction.
Discussion: Feyerabend and Laymon on Brownian Motion
Authors: George Couvalis Spyridon
Published: November 2002

In this paper, I will defend Paul Feyerabend's claim—that there are some scientific theories that cannot be refuted unless one of their rivals is first confirmed—by criticizing Ronald Laymon's well-known attack on Feyerabend's claim. In particular, I will argue both that the Second Law of Thermodynamics was not refuted before the Kinetic Theory's predictions were confirmed, and that it could not have been refuted without the confirmation of the remarkable predictions of some rival theory.
Discussion: What Does Natural Selection Explain? Correction to Sober
Authors: Neander Karen
Published: November 2002

In this paper I argue against Sober's claim that natural selection does not explain the traits of individuals. Sober argues that natural selection only explains the distribution of traits in a population. My point is that the explanation of an individual's traits involves us in a description of the individual's ancestry, and in an explanation of the distribution of traits in that ancestral population. Thus Sober is wrong, natural selection is part of the explanation of the traits of individuals.
Discussion: Axiomatics and Individuality: A Reply to Williams' “Species are Individuals”
Authors: Ereshefsky Marc
Published: November 2002

In her “Species Are Individuals” (1985), Mary Williams offers informal arguments and a sketched proof which allegedly show that species are individuals with respect to evolutionary theory. In this paper, I suggest that her informal arguments are insufficient for showing that clans are not sets and that species are individuals. I also argue that her sketched proof depends on three questionable assumptions.
Discussion: Siegel on the Rationality of Science
Authors: Baigrie Brian S.
Published: November 2002

Harvey Siegel's (1985) attempts to revive the traditional epistemological formulation of the rationality of science. Contending that “a general commitment to evidence” is constitutive of method and rationality in science, Siegel advances its compatibility with specific, historically attuned formulations of principles of evidential support as a virtue of his aprioristic candidate for science's rationality. In point of fact, this account is compatible with virtually any formulation of evidential support, which runs afoul of Siegel's claim that scientific beliefs must be evaluated with respect to their rationality. The unwelcome consequence of Siegel's view is that most any belief, scientific or pseudoscientific, can be defended as rational. Indeed, if we want to furnish a warrant for rational choice, we must turn to the very historically informed principles of evidential support that are dismissed by Siegel as providing a misleading portrait of science's rationality.
Discussion: Rationality and Anemia (Response To Baigrie)
Authors: Siegel Harvey
Published: November 2002

In his (1988), Brian Baigrie criticizes my earlier discussion of the rationality of science (Siegel 1985). In this response, I argue that (1) Baigrie misses the point of my tripartite distinction between different questions one can ask about science's rationality, (2) Baigrie's argument that the history of the development of methodological principles is crucial to philosophical discussion of the rationality of science is flawed, and (3) Baigrie's charge that my view is “anemic” rests on a failure to appreciate the point of my tripartite distinction.
Discussion: On Harold Jeffreys' Axioms
Authors: Noorbaloochi S.
Published: November 2002

It is argued that models of H. Jeffreys' axioms of probability (Jeffreys [1939] 1967) are not monotone even with I. J. Good's proposed modification (Good 1950). Hence the additivity axiom seems essential to a theory of probability as it is with Kolmogorov's system (Kolmogorov 1950).
Discussion: Quentin Smith on Infinity and the Past
Authors: Eells Ellery
Published: November 2002

In a recent commendable article, Quentin Smith (1987) exposes fatal flaws in several recent attempts to demonstrate that it is logically impossible for the past to be infinite. However, his analysis of one of these flawed arguments—involving an interesting version of Russell's “Tristram Shandy paradox”—is off the mark, as I show in this paper.
Discussion: Special Relativity and the Flow of Time
Authors: Dieks D.
Published: November 2002

N. Maxwell (1985) has claimed that special relativity and “probabilism” are incompatible; “probabilism” he defines as the doctrine that “the universe is such that, at any instant, there is only one past but many alternative possible futures”. Thus defined, the doctrine is evidently prerelativistic as it depends on the notion of a universal instant of the universe. In this note I show, however, that there is a straightforward relativistic generalization, and that therefore Maxwell's conclusion that the special theory of relativity should be amended is unwarranted. I leave open the question whether or not probabilism (or the related doctrine of the flow of time) is true, but argue that the special theory of relativity has no fundamental significance for this question.
Critical Notice: Michael Hallett's Cantorian Set Theory and Limitation of Size
Authors: Bunn Robert
Published: November 2002

The usual objections to infinite numbers, and classes, and series, and the notion that the infinite as such is self-contradictory, may ... be dismissed as groundless. There remains, however, a very grave difficulty, connected with the contradiction [of the class of all classes not members of themselves]. This difficulty does not concern the infinite as such, but only certain very large infinite classes.

Is Essentialism Unscientific?
Authors: Leplin Jarrett
Published: November 2002

This paper defends the Causal Theory of Reference against the recent criticism that it imposes a priori constraints on the aims and practices of science. The metaphysical essentialism of this theory is shown to be compatible with the requirements of naturalistic epistemology. The theory is nevertheless unable to forestall the problem of incommensurability for scientific terms, because it misrepresents the conditions under which their reference is fixed. The resources of the Causal Theory of Reference and of the traditional cluster or “network” theory of meaning for handling problems of commensurability are compared, and an alternative approach is recommended.
The Percept and Vector Function Theories of the Brain
Authors: Foss Jeff
Published: November 2002

Physicalism is anempiricaltheory of the mind and its place in nature. So the physicalist must show that current neuroscience does not falsify physicalism, but instead supports it. Current neuroscience shows that a nervous system is what I call avector function system.I provide a brief outline of the resources that empirical research has made available within the constraints of the vector function approach. Then I argue that these resources are sufficient, indeed apt, for the physicalist enterprise, by offering a vector functional, hence physicalist, theory of thepercept—the perceptual experience itself, a paradigm of phenomenally immediate, introspectively accessible consciousness.
Sober's Principle of Common Cause and The Problem of Comparing Incomplete Hypotheses
Authors: Forster Malcolm R.
Published: November 2002

Sober (1984) has considered the problem of determining the evidential support, in terms of likelihood, for a hypothesis that is incomplete in the sense of not providing a unique probability function over the event space in its domain. Causal hypotheses are typically like this because they do not specify the probability of their initial conditions. Sober's (1984) solution to this problem does not work, as will be shown by examining his own biological examples of common cause explanation. The proposed solution will lead to the conclusion, contra Sober, that common cause hypotheses explain statistical correlations and not matchings between event tokens.
Hierarchical Maximization of Two Kinds of Expected Utility
Authors: Weirich Paul
Published: November 2002

Causal decision theory produces decision instability in cases such as Death in Damascus where a decision itself provides evidence concerning the utility of options. Several authors have proposed ways of handling this instability. William Harper (1985 and 1986) advances one of the most elegant proposals. He recommends maximizing causal expected utility among the options that are causally ratifiable. Unfortunately, Harper's proposal imposes certain restrictions; for instance, the restriction that mixed strategies are freely available. To obtain a completely general method of handling decision instability, I step outside the confines of pure causal decision theory. I introduce a new kind of backtracking expected utility and propose maximizing it among the options that are causally ratifiable. In other words, I propose a hierarchical maximization of (1) conditional causal expected utility and (2) the new backtracking expected utility. I support this proposal with some intuitive considerations concerning the distinction between optimality and conditional optimality. And I prove that the proposal yields a solution in every finite decision problem.
“Truer”
Authors: Goldstick D. , O'Neill B.
Published: November 2002

When can one say that a new theory is truer than the old one it contradicts, even though neither is absolutely true? We are primarily concerned with the case in which the conflicting theories offer answers to the same questions, and so we do not introduce considerations of “logical width”. We propose that part of the new theory is truer than part of the old one when the former part gets right whatever the latter part got right while the former does not make any new mistakes. Pragmatic considerations will determine the relative importance of whatever new mistakes the new theory does make as a whole. To avoid artificial counterexamples, we restrict the parts compared to those that are “convex”. A “convex” theory is one that holds in all cases intermediate between any two cases in which it holds.
Explicating Lawhood
Authors: Vallentyne Peter
Published: November 2002

D. M. Armstrong, Michael Tooley, and Fred Dretske have recently proposed a new realist account of laws of nature, according to which laws of nature are objective relations between universals. After criticizing this account, I develop an alternative realist account, according to which (1) the nomic structure of a world is a relation between initial world-histories and world-histories, and (2) a law of nature is a fact that holds solely in virtue of nomic structure (and not, for example, in virtue of past history).
EPR: The Correlations are Still A Mystery
Authors: Kronz Frederick M.
Published: November 2002

This paper is a critical discussion of a recent article by Bas van Fraassen (1985) in which he suggests the following view: we should admit that we have no explanation of the EPR correlations, but refuse to consider the correlations as mysterious nevertheless (pp. 126–128). We shall focus on just three of the claims made by van Fraassen in support of this view. The three claims are these:

(1)

The EPR correlations cannot be explained by signals being transmitted from one component of an EPR compound to the other (pp. 114–115).

(2)

There is, in the EPR situation, no empirically verifiable action at a distance (pp. 124–126).

(3)

The demand for an explanation of the EPR correlations is similar to the Aristotelian demand of the post-Newtonian proponents of the law of inertia to explain what keeps a body moving if there are no forces impressed on it (pp. 126–128).
Are Probabilism and Special Relativity Compatible?
Authors: Maxwell Nicholas
Published: November 2002

Are probabilism and special relativity compatible? Dieks argues that they are. But the possible universe he specifies, designed to exemplify both probabilism and special relativity, either incorporates a universal “now” (and is thus incompatible with special relativity), or amounts to a many world universe (which I have discussed, and rejected as too ad hoc to be taken seriously), or fails to have any one definite overall Minkowskian-type space-time structure (and thus differs drastically from special relativity as ordinarily understood). Probabilism and special relativity appear to be incompatible after all. What is at issue is not whether “the flow of time” can be reconciled with special relativity, but rather whether explicitly probabilistic versions of quantum theory should be rejected because of incompatibility with special relativity.
Critical Notice: Patrick Suppes' Probabilistic Metaphysics
Authors: Levi Isaac
Published: November 2002

In the introduction to Probabilistic Metaphysics (1984), Patrick Suppes declares his intention to refute each of five central tenets of “neotraditional metaphysics”. These tenets run as follows:

(1)

The future is determined by the past.

(2)

Every event has a sufficient determinant cause.

(3)

Knowledge must be grounded in certainty.

(4)

Scientific knowledge can in principle be made complete.

(5)

Scientific knowledge and method can in principle be unified.
Ideological Critiques and the Philosophy of Science
Authors: Martin Jane Roland
Published: November 2002

An examination of the growing literature on gender and science leads to the conclusion that Richardson (1984) has underestimated the significance for philosophy of science of ideological critique. After describing one segment of this literature, namely, gender-based analyses of particular branches of scientific research, this paper argues that the function of at least gender ideological critique goes beyond explanation and that its explanatory function itself is broader than Richardson suggests. The paper also questions the thesis that the isolation of an ideological component in scientific research never in itself discredits that work. In so doing, it casts doubt on the adequacy of L. Laudan's taxonomy of scientific problems.
Methodological Solipsism and Explanation in Psychology
Authors: Tuomela Raimo
Published: November 2002

This paper is a discussion of the tenability of methodological solipsism, which typically relies on the so-called Explanatory Thesis. The main arguments in the paper are directed against the latter thesis, according to which internal (or autonomous or narrow) psychological states as opposed to noninternal ones suffice for explanation in psychology. Especially, feedback-based actions are argued to require indispensable reference to noninternal explanantia, often to explanatory common causes. Thus, to the extent that methodological solipsism is taken to require the truth of the Explanatory Thesis, it, too, can be regarded as untenable.
Bayesianism without the Black Box
Authors: Kaplan Mark
Published: November 2002

Crucial to bayesian contributions to the philosophy of science has been a characteristic psychology, according to which investigators harbor degree of confidence assignments that (insofar as the agents are rational) obey the axioms of the probability calculus. The rub is that, if the evidence of introspection is to be trusted, this fruitful psychology is false: actual investigators harbor no such assignments. The orthodox bayesian response has been to argue that the evidence of introspection isnotto be trusted here; it is to investigators' dispositions—not to their felt convictions—that the psychology is meant to be (and succeeds in being) faithful. I argue that this response, in both its orthodox and convex-set bayesian forms, should be rejected—as should the regulative ideals that make the response seem so attractive. I offer a different variant of bayesianism, designed to give the evidence of introspection its due and thus realize (as I claim the other forms of bayesianism cannot) the prescriptive mission of the bayesian project.
Partition-Theorems for Causal Decision Theories
Authors: Sobel Jordan Howard
Published: November 2002

Two partition-theorems are proved for a particular causal decision theory. One is restricted to a certain kind of partition of circumstances, and analyzes the utility of an option in terms of its utilities in conjunction with circumstances in this partition. The other analyzes an option's utility in terms of its utilities conditional on circumstances and is quite unrestricted. While the first form seems more useful for applications, the second form may be of theoretical importance in foundational exercises. Comparisons are made with theorems of Richard Jeffrey, Brad Armendt, and Peter Fishburn.
Identifiable Collections of Countable Structures
Authors: Osherson Daniel N. , Weinstein Scott
Published: November 2002

A model of idealized scientific inquiry is presented in which scientists are required to infer the nature of the structure that makes true the data they examine. A necessary and sufficient condition is presented for scientific success within this paradigm.
Reduction, Representation and Commensurability of Theories
Authors: Schroeder-Heister Peter , Schaefer Frank
Published: November 2002

Theories in the usual sense, as characterized by a language and a set of theorems in that language (“statement view”), are related to theories in the structuralist sense, in turn characterized by a set of potential models and a subset thereof as models (“non-statement view”, J. Sneed, W. Stegmüller). It is shown that reductions of theories in the structuralist sense (that is, functions on structures) give rise to so-called “representations” of theories in the statement sense and vice versa, where representations are understood as functions that map sentences of one theory into another theory. It is argued that commensurability between theories should be based on functions on open formulas and open terms so that reducibility does not necessarily imply commensurability. This is in accordance with a central claim by Stegmüller on the compatibility of reducibility and incommensurability that has recently been challenged by D. Pearce.
