A scientific theory is successful, according to Stanford (2000), because it is suficiently observationally similar to its corresponding true theory. The Ptolemaic theory, for example, is successful because it is sufficiently similar to the Copernican theory at the observational level. The suggestion meets the scientific realists' request to explain the success of science without committing to the (approximate) truth of successful scientific theories. I argue that Stanford's proposal has a conceptual flaw. A conceptually sound explanation, I claim, respects the ontological (...) order between properties. A dependent property is to be explained in terms of its underlying property, not the other way around. The applicability of this point goes well beyond the realm of the debate between scientific realists and antirealists. Any philosophers should keep the point in mind when they attempt to give an explanation of a property in their field whatever it may be. (shrink)

It has been argued that most truths about macroscopic states of affairs are entailed by a (hypothetical) complete descriptionPof the world in microscopic terms. In principle, micro-reductive explanations of non-microphysical truths could be constructeda priori.Against this claim, I show that reductive explanation requires knowledge about the phenomena to be reduced which cannot bea prioriextracted from microphysical information alone. Such reductions proceed in two steps: a “reductionR0” (“role-occupant”) establishes that a macroproperty M plays a certain causal role (specified in macro-terms), while (...) a “reductionMM” (“micro-macro”) establishes that some microproperty gives rise toM.

A set of hypotheses is formulated for a connectionist approach to cognitive modeling. These hypotheses are shown to be incompatible with the hypotheses underlying traditional cognitive models. The connectionist models considered are massively parallel numerical computational systems that are a kind of continuous dynamical system. The numerical variables in the system correspond semantically to fine-grained features below the level of the concepts consciously used to describe the task domain. The level of analysis is intermediate between those of symbolic cognitive models (...) and neural models. The explanations of behavior provided are like those traditional in the physical sciences, unlike the explanations provided by symbolic models.Higher-level analyses of these connectionist models reveal subtle relations to symbolic models. Parallel connectionist memory and linguistic processes are hypothesized to give rise to processes that are describable at a higher level as sequential rule application. At the lower level, computation has the character of massively parallel satisfaction of soft numerical constraints; at the higher level, this can lead to competence characterizable by hard rules. Performance will typically deviate from this competence since behavior is achieved not by interpreting hard rules but by satisfying soft constraints. The result is a picture in which traditional and connectionist theoretical constructs collaborate intimately to provide an understanding of cognition. (shrink)

I begin by defending condition (i) against five objections (section 2). Following this, I show that the theory that laws obtain contingently encounters three problems that are solved by the theory that laws are metaphysically necessary (section 3). In section 3, I criticize the regularity theory of natural laws and the universals theory of Armstrong, Dretske and Tooley, and also show how the metaphysical theory solves the “inference problem” that Van Fraassen (1989) posed for any theory of natural laws.

The anti?Cartesian idea that a person's thoughts are not entirely fixed by what goes on inside that person's head is suggested by Hegel, and echoed in Wittgenstein and Frege. An argument for the view has recently been given by Tyler Burge. This paper claims that Burge's data can be explained better by an individualistic theory. The basic idea is that an individual's thoughts are specified analogically, in ordinary discourse, through the model of a language. Though the modelling?sentences are public, the (...) thoughts of the individual are inner states whose identity does not depend upon those sentences. They have content naturally, whether or not content happens to be ascribed to them. (shrink)

How should biological behaviour be modelled? A relatively new approach is to investigate problems in neuroethology by building physical robot models of biological sensorimotor systems. The explication and justification of this approach are here placed within a framework for describing and comparing models in the behavioural and biological sciences. First, simulation models – the representation of a hypothesis about a target system – are distinguished from several other relationships also termed “modelling” in discussions of scientific explanation. Seven dimensions on which (...) simulation models can differ are defined and distinctions between them discussed: 1. Relevance: whether the model tests and generates hypotheses applicable to biology. 2. Level: the elemental units of the model in the hierarchy from atoms to societies. 3. Generality: the range of biological systems the model can represent. 4. Abstraction: the complexity, relative to the target, or amount of detail included in the model. 5. Structural accuracy: how well the model represents the actual mechanisms underlying the behaviour. 6. Performance match: to what extent the model behaviour matches the target behaviour. 7. Medium: the physical basis by which the model is implemented. No specific position in the space of models thus defined is the only correct one, but a good modelling methodology should be explicit about its position and the justification for that position. It is argued that in building robot models biological relevance is more effective than loose biological inspiration; multiple levels can be integrated; that generality cannot be assumed but might emerge from studying specific instances; abstraction is better done by simplification than idealisation; accuracy can be approached through iterations of complete systems; that the model should be able to match and predict target behaviour; and that a physical medium can have significant advantages. These arguments reflect the view that biological behaviour needs to be studied and modelled in context, that is, in terms of the real problems faced by real animals in real environments. Key Words: animal behaviour; levels; models; neuroethology; realism; robotics; simulation. (shrink)

According to quasi-empiricism, mathematics is very like a branch of natural science. But if mathematics is like a branch of science, and science studies real objects, then mathematics should study real objects. Thus a quasi-empirical account of mathematics must answer the old epistemological question: How is knowledge of abstract objects possible? This paper attempts to show how it is possible.The second section examines the problem as it was posed by Benacerraf in Mathematical Truth and the next section presents a way (...) of looking at abstract objects that purports to demythologize them. In particular, it shows how we can have empirical knowledge of various abstract objects and even how we might causally interact with them. (shrink)

Some eliminativists have predicted that a developed neuroscience will eradicate the principles and theoretical kinds (belief, desire, etc.) implicit in our ordinary practices of mental state attribution. Prevailing defenses of common-sense psychology infer its basic integrity from its familiarity and instrumental success in everyday social commerce. Such common-sense defenses charge that eliminativist arguments are self-defeating in their folk psychological appeal to the belief that eliminativism is true. I argue that eliminativism is untouched by this simple charge of inconsistency, and introduce (...) a different dialectical strategy for arguing against the eliminativist. In keeping with the naturalistic trend in the sociology and philosophy of science, I show that neuroscientists routinely rely on folk psychological procedures of intentional state attribution in applying epistemically reliable standards of scientific evaluation. These scientific contexts place ordinary procedures of attribution under greater stress, producing evidence of folk psychological success that is less equivocal than the evidence in mundane settings. Therefore, the dependence of science on folk psychology, when combined with an independently plausible explanatory constraint on reduction and an independently motivated notion of theoretical stress, allows us to reconstitute the charge of (neurophilic) eliminativist inconsistency in a more sophisticated form.

Knowledge requires truth, and truth, we suppose, involves unflawed representation. Science does not provide knowledge in this sense but rather provides models, representations that are limited in their accuracy, precision, or, most often, both. Truth as we usually think of it is an idealization, one that serves wonderfully in most ordinary applications, but one that can terribly mislead for certain issues in philosophy. This article sketches how this happens for five important issues, thereby showing how philosophical method must take into (...) account the idealized nature of our familiar conception of truth.

If a parsimony criterion may be used to choose between theories that make different predictions, may the same criterion be used to choose between theories that are predictively equivalent? The work of the statistician H. Akaike (1973) is discussed in connection with this question.

It will be the thesis of this paper that there are among our mental acts some which fall into the category of real material relations. That is: some acts are necessarily such as to involve a plurality of objects as their relata or fundamenta. Suppose Bruno walks into his study and sees a cat. To describe the seeing, here, as a relation, is to affirm that it serves somehow to tie Bruno to the cat. Bruno's act of seeing, unlike his (...) feeling depressed, his putative thinking-about-Santa-Claus or his musing, abstractedly, about the tallest spy, has at least two fundamenta: it is, as a matter of necessity, dependent for its existence upon both Bruno himself and the cat that he sees. This idea will naturally raise echoes of Russell's doctrine of knowledge by acquaintance. 'I am acquainted with an object', Russell tells us, 'when I have a direct cognitive relation to that object, i. e. when I am directly aware of the object itself' (1918, p. 209). And indeed a distinction in many ways like that between acquaintance and description will find a place within the theory here projected, but there are crucial differences. (shrink)

It has been claimed that modern long-standing scientific theories are fertile, in the sense of having been progressively successfully modified to meet new experimental observations or theoretical developments in related areas, and that these modifications arise naturally from each preceding version of the theory. McMullin has advanced this form of fertility as a vindication of scientific realism, since if the theories did not approximate the real, the observation would be inexplicable. In response Nolan has denied the existence of fertility in (...) this sense as an independent virtue. The present paper argues that the rebuttal is flawed.

The principle of charity (“Charity”), in one form or other, is held by many and for various reasons. After cataloging discernible kinds of Charity, I focus on the most familiar versions as found in Davidson, Dennett, Devitt, Lewis, Putnam, Quine, Stich, and others. To begin with, I argue that such versions of Charity are untenable because beliefs cannot be counted, and even if they could be counted there is reason to believe that true beliefs need not outnumber false beliefs. Next (...) I rebut one of the arguments behind Charity, the intelligibility argument. If indeed beliefs are postulated simply as a way to make some system intelligible (predictable and explicable) then a number of theses ensue. First, it would be perfectly intelligible to ascribe mostly false beliefs to an intentional system, or even entirely false beliefs. Second, lower animals would have beliefs. Third, it would sometimes make sense to ascribe beliefs even to inanimate beings. And fourth, the resulting indeterminacy of belief-ascription would suggest a kind of irrealism about belief which may in turn be expressed by the slogan that rejects the container metaphor of the mind.

In the on-going debate between scientific realism and its various opponents, a crucial role in challenging the realist claim that success of scientific theories must be attributed to their approximate truth is played by the so-called pessimistic meta-induction: Arguing that the history of science boils down to a succession of theories which, though successful at a time, were eventually discarded only to be replaced by alternative theories which in turn met with the same fate, it purports to show that the (...) empirical success of scientific theories cannot have any bearing on claims about their truth-likeness. Yet, the same historical record suggests a possible strategy to counter this argument. Far from being a barren wasteland, it contains cases which point to the need of adopting a selective attitude when passing judgments about truth-likeness of theories. In this vein, Psillos has proposed the so-called divide et impera move. It consists in pointing out that responsibility for the success of a theory should be attributed to an indispensable core element in it, acting in unison with other elements reflecting the concrete historical conditions under which the theory was formulated. In what follows it is argued that the discovery of Kepler's first two laws and the transition to Newtonian mechanics provides a notable case to exhibit the divide et impera move. All the more so, since—as will be shown—Kepler himself employs a variant of this move, a fact that sheds light on the philosophical implications of his theories. As a result, it will be argued that the appropriate selective attitude towards theories becomes solidly warranted if wedded to the diachronic element in the process of a theory's development.

One would have thought that Fodor's justly famous computational views about the mind and his covariation approaches to content owed a lot to the twentieth century that he now reviles. On the other hand, a number of lines he pursues in the target article make one wonder whether he hasn’t perhaps changed his mind about those famous views. Specifically, I argue that his own theory of content is open to the very same objections he raises against ‘sorting’ theories, and that (...) the supposed circularity in implicit definitions of logical particles can easily be avoided by the very functional/computational definitions that he fathered decades ago. Fodor's rejection here of sorting and implicit definition does make one worry that he is now opting for what seems the only atomistic alternative that would seem to be left, the first‐person meaning mysticism of the very Cartesian sort he now claims to favor, but from which I would have thought twentieth century role and discrimination views were a welcome relief. Despite all these worries, however, I concede that one could probably do worse than assume for the nonce that meaning is atomic, or, anyway, unanalyzed, and get on with investigating the mind on that basis—but keeping the options open.

I articulate and defend a new theory of what it is for a physical system to implement an abstract computational model. According to my descriptivist theory, a physical system implements a computational model just in case the model accurately describes the system. Specifically, the system must reliably transit between computational states in accord with mechanical instructions encoded by the model. I contrast my theory with an influential approach to computational implementation espoused by Chalmers, Putnam, and others. I deploy my theory (...) to illuminate the relation between computation and representation. I also rebut arguments, propounded by Putnam and Searle, that computational implementation is trivial.

Social thinkers often use the concept of intersubjectivity to mark out a problem of theoretical sociology: If people are unable to look into each others' minds, why do they often understand each other nonetheless? This issue has been debated extensively by philosophers and sociologists in three largely disconnected discourses. The article investigates the three discourses for isolable ideas that can be fitted into a sociological answer to the problem of intersubjectivity. An interactional solution, fully coherent with key insights from the (...) discourses, is offered at the end of the article. Its main point is to identify coordinative interactional mechanisms that compel participants to "make themselves understandable" vis-à-vis their interaction partners. (shrink)

ABSTRACT: The article examines the controversial relation of scientific realism with quantum mechanics. To this end, two distinct discussions are invoked: the discussion about ‘realism’ in the context of quantum mechanics and the discussion about ‘scientific realism’ in the context of the general philosophy of science. The aim is to distinguish them in order, first, to argue that the former—revolving around ‘local realism’ and the theorems of Bell and Kochen–Specker—unjustifiably identifies realism with features of a particular worldview, and thereby fosters (...) the impression that the failure of ‘local realism’ in quantum experiments constitutes a failure of scientific realism too; and, second, in light of the latter discussion, to claim that scientific realism and quantum mechanics can be compatible—there is ground for dealing with quantum measurement simply as a physical mind-independent interaction. Therefore, a realist approach to the theory is possible despite its notorious measurement problem, even if th... (shrink)

Observations from philosophy and psychology heavily favor the Empiricist tenet that many lexical concepts are learned. However, many observations also heavily favor the Nativist tenet that such concepts are representationally atomic. Fodor Representations: Philosophical essays on the foundations of cognitive science, 1981, LOT2: The language of thought revisited, 2008) has famously argued that representationally atomic concepts cannot be learned, at least not learned by hypothesis formation and testing. Concept theorists who want to preserve observations about concept learning have developed acquisition (...) models on which the acquired concepts are either non-atomic or are acquired by a process that doesn’t involve hypothesis formation and testing. I offer a model, Baptizing Meanings for Concepts, in which representationally atomic concepts are learned by hypothesis formation and testing. The concepts are learned by the agent’s hypothesizing the existence of a latent/hidden/imperceptible property in objects to explain the objects’ perceptible similarities. Once a hidden property is hypothesized, a new atomic mental name is assigned to it, and this atomic name becomes the concept. Any connections between the name and the representations involved in linking the name to its referent are stored as contingent. Further experience may give the agent reason to revise its hypotheses about latent properties as explanations for its observations. I discuss a software robot implementation of the BMC process that uses a Bayesian learning network. The implementation provides an existence proof of the possibility of learning representationally atomic concepts by hypothesis formation and testing. (shrink)

A famous essay by Wigner is reexamined in view of more recent developments around its topic, together with some remarks on the metaphysical character of its main question about mathematics and natural sciences.

It is fundamental assumption in nursing theory that it is important for nurses to understand how patients experience states of ill health. This assumption is often related to aims of empathic understanding, but normative principles of social interpretation can have an important action‐guiding role whenever nurses seek to understand patients’ subjective horizons on the basis of active or passive expressions of meaning. The aim of this article is to present a philosophical theory of concept possession and to argue that it (...) can shed light on how nurses should seek to understand patients’ subjective perspectives on the meaning of illness. The two basic ideas in the theory are that patients’ beliefs and thoughts about their experiences involve concepts and that concepts can be communicated on the basis of shared implicit conceptions of what they mean. These conditions of understanding have a striking application: nurse‐patient communication is limited by many contextual factors, but it is often possible for nurses to detect shared implicit conceptions of the meaning of concepts of disease and illness. Furthermore, by acting as sympathetic linguistic experts and creating an atmosphere for dialogue, nurses can make patients feel comfortable about deferring to medical explanations of meaning that can constitute a communicative platform. The last part of the article uses a number of cases studies to show how these implications can be implemented as conceptual tools for securing meaningful communication about illness experiences in patient dialogue.

Influential holistic analyses of patient perspectives assume that the concepts that patients associate with medical terms are formed by their total social and cultural contexts. Holistic analyses presuppose conceptual role semantics in the sense that they imply that a medical term must have the same role for a nurse and a patient in order for them to associate the same concept with the term. In recent philosophy of mind, social externalism has emerged as a non‐holistic alternative to conceptual role theories. (...) According to social externalism, a nurse and a patient express the same concept by a term if they both have a minimal or better understanding of the term. Three arguments in favour of social externalism are presented in connection with nurse–patient interaction. The first concerns successful communication, the second focuses on belief reports made by patients and the third centres on the need for including medical terms in medical discourse. Finally, the practical implications of the arguments are clarified. The most important of these is that, in cases of misunderstanding, a nurse should not conform to a patient's idiosyncratic understanding, but instead correct the mistaken applications of the term in question.

‘Water is H 2 O’ is naturally construed as an equivalence. What are the things to which the two predicates ‘is water’ and ‘is H 2 O’ apply? The equivalence presupposes that substance properties are distinguished from phase properties. A substance like water (H 2 O) exhibits various phases (solid, liquid, gas) under appropriate conditions, and a given (say liquid) phase may comprise several substances. What general features distinguish substance from phase properties? I tackle these questions on the basis of (...) an interpretation of a theorem of thermodynamics known as Gibbs' phase rule which systematically relates these two kinds of feature of matter. The interpretation develops the idea that the things substance and phase predicates apply to are quantities of matter which sustain mereological relations and operations and exploits these mereological features in distinguishing the two kinds of property. Gibbs' phase rule is a macroscopic principle applicable for macroscopic intervals of time. Bringing intervals of time into the picture calls for a more detailed consideration of the relation between macroscopic equilibria and the corresponding dynamic equilibria at the microlevel and throws into question the simple idea that quantities can always be regarded as collections of molecules. The account provides some insight into how the continuous, macroscopic conception of matter (‘gunk’) is reconciled with the discrete microscopic conception and illuminates the interpretation of substances present in mixtures.

According to microessentialism, it is necessary to resort to microstructure in order to adequately characterise chemical substances such as water. But the thesis has never been properly supported by argument. Kripke and Putnam, who originally proposed the thesis, suggest that a so-called stereotypical characterisation is not possible, whereas one in terms of microstructure is. However, the sketchy outlines given of stereotypical descriptions hardly support the impossibility claim. On the other hand, what naturally stands in contrast to microscopic description is description (...) in macroscopic terms, and macroscopic characterisations of water are certainly possible. This suffices to counter the claim that microdescriptions are necessary. Whether it counters the impossibility claim depends on whether all macroscopic descriptions are stereotypical (stereotypical descriptions presumably being macroscopic). In so far as systematic import of “stereotypical” can be determined, it would seem not. But some macroscopic characterisations have definite affinity with everyday knowledge, which presumably stands in conflict with the spirit of the impossibility claim. Since what is characterised are properties expressed by predicates like “is water”, the necessity of identity has no bearing here, and matters of interpretation pose problems for claims to the effect that science fixes the extension of “water” as ordinarily understood.

Abstract: Despite all the critical scrutiny they have received recently, contextualist views in philosophy are still not well understood. Neither contextualists nor their opponents have been entirely clear about what contextualist theses amount to and what they are based on. In this article I show that there are actually two kinds of contextualist view that rest on two very different semantic phenomena, namely, semantic incompleteness and semantic indeterminacy . I explain how contextualist approaches can be used to dissolve certain debates (...) in philosophy. According to such approaches, the same philosophical thesis can be correctly endorsed in some contexts and correctly denied in others: it is thus pointless to seek a context-independent solution to debates about this thesis. My purpose is not to defend particular contextualist views but to lay out the general framework on which they rest: this allows us to see more clearly the similarities and differences among contextualist views defended in various areas of philosophy.

The paper argues that the use of epistemic terms, prominently “… knows” and even “… knows a priori/a posteriori” is context-sensitive along several dimensions. Besides the best known dimension of quality of evidence (lower quality for less demanding context, and higher one for more demanding), there is a dimension of depth (shallow justification for superficial evaluation, and deeper justification for deeper probing evaluation contexts). This claim is illustrated by context-dependent ascription of apriority and aposteriority. The argument proposed here focuses upon (...) the status of propositions that are analytic in empirical concepts (like “Whales are animals”). It is a commonplace in epistemology that any analytic proposition (including e-analytic ones) is a priori. The paper claims that propositions analyzing empirical concepts are an interesting counterexample. It develops the following argument: Many such propositions have empirical counterparts that are expressed by the same form-of-words. (E.g., the form of words “Whales are mammals” can express both an e-analytic proposition and an empirical statement.) They normally derive from their empirical counterparts. Beliefs in such propositions, can be explicitly justified either a priori, by pointing out their conceptual, analytic status, or by reverting to their empirical counterparts. In contexts of very superficial evaluation, one may justify such an analytic belief in the first, conceptual way. In most contexts a belief in a proposition analyzing an empirical concept is being justified by appeal to its empirical counterparts. The empirical justification is normally taken as being ultimate. Empirical counterparts are derivationally deeper than the corresponding analytic propositions, and empirical justification is deeper than a priori one as well. Therefore, propositions analyzing empirical concepts are deeply a posteriori and superficially a priori. (shrink)
