In reviewing Finocchiaro's book, I argue that Galileo deserved to be found guilty for the charges against him. A measure of Finocchiaro's scrupulously fair-minded presentation of the issues surrounding the Galileo Affair is the fact that a contrary case against his own exculpatory evaluation may be inferred from his meticulous scholarship. Specifically, to acknowledge that the standards of evaluation and judgment have changed since 1633 is not in any way to diminish Galileo's greatness but, on the contrary, to recognize his (...) visionary insights. Even to acknowledge that he was justly condemned by standards that we no longer accept in science or theology is not to detract from his deserved place in the firmament of scientific genius.

Context: The current situation in philosophy of science includes central, ongoing debates about realism and anti-realism. The same question has been central to the theorising of radical constructivism and, in particular, to its implications for educational theory. However the constructivist literature does not make significant contact with the most important, mainstream philosophical discussions. Problem: Despite its overwhelming influence among educationalists, I suggest that the “radical constructivism” of Ernst Glasersfeld is an example of fashionable but thoroughly problematic doctrines that can have (...) little benefit for practical pedagogy or teacher education. My critique has a positive goal: it is important to understand why constructivism has generated such severe polarization and disputation. A symptom of the problem is the concern with the most abstruse and obdurate problems of philosophy that have no conceivable bearing on educational practice or anything else, for that matter. The diagnosis is confirmed by those pedagogical recommendations that are allegedly derived from radical constructivism that are touted as revolutionary but are platitudes of common sense. I suggest that, ironically, this observation itself provides some pedagogical insight. Method: The approach adopted for the topic is critical, philosophical analysis of the various claims and theses of radical constructivism in the light of philosophy of science and psychology. Results: The findings of the paper are that central theoretical claims of constructivism are couched in an unclear and unnecessary jargon that obscures the implausibility or banality of these claims. Implications: The value of the paper lies in providing an analysis and critique of central, influential claims of radical constructivism both in relation to issues in epistemology and also in relation to the alleged bearing of these claims on pedagogy. It is suggested that, contrary to the claims of radical constructivists, there are few if any implications for practice and applications. (shrink)

Kirsten Besheer has recently considered Descartes’ doubting appropriately in the context of his physiological theories in the spirit of recent important re-appraisals of his natural philosophy. However, Besheer does not address the notorious indubitability and its source that Descartes claims to have discovered. David Cunning has remarked that Descartes’ insistence on the indubitability of his existence presents “an intractable problem of interpretation” in the light of passages that suggest his existence is “just as dubitable as anything else”. However, although the (...) cogito argument is widely thought to be central to the force of Descartes’ indubitability, for his part, Cunning does not consider its relevance and force. Accordingly, this article is concerned with the cogito argument and the question central to Hintikka’s seminal contribution, described by Cottingham as “Perhaps the most debated question,” namely, whether or not the cogito can be construed as a logical inference. Clearly, an inferential account has the potential to explain the certainty of Descartes’ conclusion that he exists. Recently, Sarkar offers what he characterizes as “novel and fairly conclusive reasons why the cogito cannot be construed as an argument,” asserting “the discovery of the cogito can only be an intuition not a deduction.” Obviously, it would greatly support the opposing inferential construal if a remotely plausible logical argument could be proposed. Toward this end, I defend the virtues of my ‘Diagonal’ account of Descartes’ cogito Above all, I show how my analysis meets the requirement that any satisfactory solution to the problem of the cogito would reconcile Descartes’ claim that the cogito is a certain inference with his claim that it is an intuitive kind of knowledge. Through a critical discussion of analyses such as that of Gallois , I show that it is possible to provide a textually faithful analysis that permits seeing the cogito as both inference and intuition because it may be seen as an exercise in the mathematical method of Analysis. Above all, as Feldman requires, I show that the Diagonal account is not only textually elegant, but permits crediting Descartes with a worthy insight, thereby resolving the tension between what Howell has termed the Humean and Cartesian problems, namely, the elusiveness and the certainty of the self.

Methodological questions concerning Chomsky’s generative approach to linguistics have been debated without consensus. The status of linguistics as psychology, the psychological reality of grammars, the character of tacit knowledge and the role of intuitions as data remain heatedly disputed today. I argue that the recalcitrance of these disputes is symptomatic of deep misunderstandings. I focus attention on Michael Devitt’s recent extended critique of Chomskyan linguistics and I suggest that his complaints are based on a failure to appreciate the special status (...) of Chomsky’s computational formalisms found elsewhere in cognitive science. Devitt ascribes an intentional conception of representations that Chomsky repudiates and that is independently implausible. I argue that Devitt’s proposed “linguistic reality” as the proper subject matter of linguistics neglects the problems of tokens as opposed to types and he misses the force of Chomsky’s arguments against Behaviourism and nominalism. I suggest that Devitt’s case against intuitions as data misunderstands their standard role throughout perceptual psychology. Finally, of more general interest, I argue that Devitt’s position exemplifies compelling errors concerning mental representation seen throughout cognitive science and philosophy of mind. (shrink)

In seeking to understand the extraordinary persistence and recalcitrance of the problems of intentionality, it is instructive to focus attention on one particular facet of the issue. The question of misrepresentation has been discussed recently as a puzzling aspect of the overall problem of the semantics of mental representation (Fodor 1984, 1994, Dretske 1994) and I propose to explore this issue as a loose thread which may be pulled to unravel the rest of the tangled ball.

I do not think that the world or the sciences would ever have suggested to me any philosophical problems. What has suggested philosophical problems to me is things which other philosophers have said about the world or the sciences. (G.E. Moore, 1942, p. 14).

The imagery debate re-enacts controversies persisting since Descartes. The controversy remains important less for what we can learn about visual imagery than about cognitive science itself. In the tradition of Arnauld, Reid, Bartlett, Austin and Ryle, Pylyshyn’s critique exposes notorious mistakes being unwittingly rehearsed not only regarding imagery but also in several independent domains of research in modern cognitive science.

Robert Cummins [(1996) Representations, targets and attitudes, Cambridge, MA: Bradford/MIT, p. 1] has characterized the vexed problem of mental representation as "the topic in the philosophy of mind for some time now." This remark is something of an understatement. The same topic was central to the famous controversy between Nicolas Malebranche and Antoine Arnauld in the 17th century and remained central to the entire philosophical tradition of "ideas" in the writings of Locke, Berkeley, Hume, Reid and Kant. However, the scholarly, (...) exegetical literature has almost no overlap with that of contemporary cognitive science. I show that the recurrence of certain deep perplexities about the mind is a systematic and pervasive pattern arising not only throughout history, but also in a number of independent domains today such as debates over visual imagery, symbolic systems and others. Such historical and contemporary convergences suggest that the fundamental issues cannot arise essentially from the theoretical guise they take in any particular case. (shrink)

The possible role of language in intermodular communication and non-domain-specific thinking is an empirical issue that is independent of the “vehicle” claim that natural language is “constitutive” of some thoughts. Despite noting objections to various forms of the thesis that we think in language, Carruthers entirely neglects a potentially fatal objection to his own preferred version of this “cognitive conception.”.

The problem of explaining the mind persists essentially unchanged today since the time of Plato and Aristotle. For the ancients, of course, it was not a question of the relation of mind to brain, though the question was fundamentally the same nonetheless. For Plato, the mind was conceived as distinct from the body and was posited in order to explain knowledge which transcends that available to the senses. For his successor, Aristotle, the mind was conceived as intimately related to the (...) body as form is related to substance. On this conception, the mind is an abstract property or condition of the body itself -. (shrink)

The self-advertising, at least, suggests that 'situated cognition' involves the most fundamental conceptual re-organization in AI and cognitive science, even appearing to deny that cognition is to be explained by mental representations. In their defence of the orthodox symbolic representational theory, A. Vera and H. Simon (1993) have rebutted many of these claims, but they overlook an important reading of situated arguments which may, after all, involve a revolutionary insight. I show that the whole debate turns on puzzles familiar (...) from the history of philosophy and psychology and these may serve to clarify the current disputes. (shrink)

In their study of reasoning with diagrammatic and non-diagrammatic representations, Larkin and Simon (1987) are concerned with _external_ representations and explicitly avoid drawing inferences about the bearing of their work on the issue of internal, mental representations. Nonetheless, we may infer the bearing of their work on internal representations from the theories of Kosslyn, Finke and other ‘pictorialists’ who take internal representations to be importantly like external ones regarding their ‘privileged’ spatial properties of depicting and resembling their referents. Thus, Finke (...) (1990) suggests that “perceptual interpretive processes are applied to mental images in much the same way that they are applied to actual physical objects. In this sense, imagined objects can be “interpreted” much like physical objects” (1990, p. 18). Elsewhere he suggests that “The image discoveries which then ‘emerge’ resemble the way perceptual discoveries can follow the active exploration and manipulation of physical objects” (1990, p. 171).

The recent republication of David Bloor's Knowledge and Social Imagery in a second edition provides an occasion to reappraise the celebrated work which launched the so-called Strong Programme in the sociology of scientific knowledge. This work embodies the general outlook and foundational principles in a way that is still characteristic of its descendents. Above all, the recent republication of Bloor's original book is evidence of the continuing interest and importance of the work, but it also provides the clearest evidence of (...) the shortcomings of the enterprise. The arguments presented in the bulk of the book have received relatively little attention by comparison with the principal tenets enunciated in the first few pages. Accordingly, a detailed examination is made of these original arguments which were so influential in establishing the sociology of scientific knowledge. A close analysis reveals their seemingly unnoticed vacuity, as well as a vast discrepancy between the radical tenets of the Strong Programme and the theses that are actually defended in the body of Bloor's text. In this sense, this article serves to complement and reinforce Mario Bunge's recent masterful survey of the field, which he describes as "a grotesque cartoon of scientific research.". (shrink)

The republication of David Bloor's Knowledge and Social Imagery is evidence of the continuing interest and importance of the work but also provides the clearest evidence of the shortcomings of the enterprise. The new Afterword of Bloor's second edition addresses criticisms of the Strong Programme, but the theses which Bloor now defends are substantially weaker claims than the iconoclastic tenets of the original manifesto. Moreover, in a related strategy, Bloor asserts that criticisms made since 1975 have given him no reason (...) to modify the original text, but there are judicious alterations which are revealing. These unacknowledged alterations are documented here. Bloor's Strong Programme was founded on the diametrical opposition between his causal sociological approach and the allegedly a?causal rationalist, psychologist or ?teleological? approach. However, once it was shown that the teleological position is not the straw?man he represented it to be, Bloor's diametrical opposition left him no retreat. Just as Bloor weakens the original claims of the Strong Programme to make them appear compatible with cognitive science, so he eradicates the suggestion that the opposing teleological position was ever as absurd as he had portrayed it. The common rationale of these independent tactics leaves little question about their purpose ? and their futility. (shrink)

are needed on which the contending accounts deliver different predictions. The question of re-interpreting images can be seen.

Abstract The accumulated case studies in the Sociology of Scientific Knowledge have been taken to establish the Strong Programme's thesis that beliefs have social causes in contradistinction to psychological ones. This externalism is essentially a commitment to the stimulus control of behaviour which was the principal tenet of orthodox Skinnerian Behaviorism. Offered as ?straight forward scientific hypotheses? these claims of social determination are asserted to be ?beyond dispute?. However, the causes of beliefs and especially their contents has also been the (...) subject of intense study in the quite different domain of cognitive science where internal states, images, rules, representations and schemas are postulated as explanatory constructs. Such explanations which postulate mental states are described by Bloor as infected by the ?disease? of ?psychologism? and Bloor has defined his Strong Programme in terms of its diametrical opposition to mentalistic theories. For example, Bloor has explicitly endorsed the Behaviourist rejection of mental representations such as images. Accordingly, a direct comparison of these radically divergent approaches to a common subject matter is of considerable interest. The paper attempts to reveal the unnoticed enormity and recidivism of the sociological programme, and how its vulnerability is betrayed in Bloor's response to criticism on central issues. (shrink)

A fully adequate solution to Newcomb’s Problem (Nozick 1969) should reveal the source of its extraordinary elusiveness and persis- tent intractability. Recently, a few accounts have independently sought to meet this criterion of adequacy by exposing the underlying source of the problem’s profound puzzlement. Thus, Sorensen (1987), Slezak (1998), Priest (2002) and Maitzen and Wilson (2003) share the ‘no box’ view according to which the very idea that there is a right choice is mis- conceived since the problem is ill-formed (...) or incoherent in some way. Among proponents of this view, Richard Jeffrey (2004) recently declared that he renounces his earlier position that accepted Newcomb problems as genuine decision problems. Significantly, Jeffrey suggests that “New- comb problems are like Escher’s famous staircase on which an unbroken ascent takes you back where you started” (Jeffrey (2004; 113). Jeffrey’s analogy is apt for a puzzle whose specific logical features can be pre- cisely articulated. Along the lines of these related approaches, I propose to improve and clarify them by providing such a deeper analysis that elucidates their essential, related insights. (shrink)
