Donald Davidson has two central aims in his celebrated paper ‘Mental Events.’ First, he argues for the impossibility of ‘strict … laws on the basis of which mental events can be predicted and explained’. I shall call the resulting view ‘mental anomalism.’ Second, he argues, based partially on this impossibility, for a version of monism which holds that every mental event is token-identical with some physical event. This second aim puts constraints on how the argument for mental anomalism can plausibly (...) proceed. That argument cannot assume anything that presupposes monism or adversely affects the argument for it. When elaborated, this constraint by itself rules out otherwise attractive conceptions of how the argument for mental anomalism works. More generally, in order to be compelling, the overall argument for anomalous monism ought not to incorporate excessively controversial presuppositions even if they do not themselves beg any questions about monism. The argument needs to be built upon relatively intuitive premises. (shrink)

Jerry Fodor and Ernest Lepore have recently criticized Davidson's methodology of radical interpretation because of its apparent failure to reflect how actual interpretation is achieved. Responding to such complaints, Davidson claims that he is not interested in the empirical issues surrounding actual interpretation but instead focuses on the question of what conditions make interpretation possible. It is argued that this exchange between Fodor and Lepore on one side, and Davidson on the other, cannot be viewed simply as a naturalist reaction (...) to non-naturalist philosophical inquiry. Through a careful excavation of the hidden assumptions and commitments underlying this debate, we recognize a more serious disagreement over the intellectual obligations of naturalism; a position with a firm hold on current philosophical imaginations. In the process, we gain a new appreciation for how such commitments shape these naturalist positions, and recognize that any resolution to this specific debate will require careful attention to the divergent commitments that are its real source.

Alan Turing’s 1950 imitation game has been widely understood as a means for testing if an entity is intelligent. Following a series of papers by Diane Proudfoot, I offer a socio-technological interpretation of Turing’s paper and present an alternative way of understanding both the imitation game and Turing’s concept of intelligence. Turing, I claim, saw intelligence as a social concept, meaning that possession of intelligence is a property determined by society’s attitude toward the entity. He realized that as long as (...) human society held a prejudiced attitude toward machinery—seeing machines a priori as mindless objects—machines could not be said to be intelligent, by definition. He also realized, though, that if humans’ a priori, chauvinistic attitude toward machinery changed, the existence of intelligent machines would become logically possible. Turing thought that such a change would eventually occur: He believed that when scientists overcome the technological challenge of constructing sophisticated machines that could imitate human verbal behavior—i.e., do well in the imitation game—humans’ prejudiced attitude toward machinery will have altered in such a way that machines could be said to be intelligent. The imitation game, for Turing, was not an intelligence test, but a technological aspiration whose realization would likely involve a change in society’s attitude toward machines. (shrink)

In this paper, we will try to confront Quine’s and Davidson’s holistic position through Davidson’s thesis of the mental as a non-ontological category. In this regard, since Davidson came to this position through the thesis of the mental as a decidedly conceptual category, we will try to show how this approach does not, nevertheless, rule out the possibility of its interpretation in ontological terms. However, in what follows we will draw attention to the fact that the mental can be interpreted (...) so that it proves to be immune to ontologizing in Quine’s sense. This would be the evidence of different ways, which are not necessarily compatible, to argue for Davidson’s central thesis - the thesis about holistic character of the mental - as well as, which is closely related, a certain difference that exists between Davidson’s view of the mental as a conceptual category on the one hand, and a holistic category on the other.

Disertační práce se zabývá problematikou připisování myšlení jiným entitám, a to pomocí imitační hry navržené v roce 1950 britským filosofem Alanem Turingem. Jeho kritérium, známé v dějinách filosofie jako Turingův test, je podrobeno detailní analýze. Práce popisuje nejen původní námitky samotného Turinga, ale především pozdější diskuse v druhé polovině 20. století. Největší pozornost je věnována těmto kritikám: Lucasova matematická námitka využívající Gödelovu větu o neúplnosti, Searlův argument čínského pokoje konstatující nedostatečnost syntaxe pro sémantiku, Blockův návrh na použití brutální síly pro (...) řešení imitační hry, Frenchova teorie subkognitivních informací a Michieho skepticismus ohledně možnosti umělého vědomí. Závěr práce zachycuje současný stav recepce Turingova testu a představuje pokusy o jeho praktickou realizaci, například v každoroční soutěži o Loebnerovu cenu. Autor práce zastává názor, že ani po více než šedesáti letech od uveřejnění Turingova paradigmatického eseje stále neexistují žádné vážné důvody pro zamítnutí jeho tvrzení. Tradiční komputační funkcionalismus možná není ideální teorií vysvětlující činnost myslí a jako slibnější se může jevit vývoj v neurálních vědách, ale Turingův test je přesto užitečným a snad i jediným nástrojem pro detekci inteligence u lidmi vytvořených strojů.

This article raises two questions about Robert Myers and Claudine Verheggen's terrific book, Donald Davidson's Triangulation Argument: A Philosophical Inquiry. The first question, concerning the first part of the book, is whether, starting from the assumption that a solitary individual cannot have thought contents, we can show that adding another individual to the picture cannot resolve the problem. The second question, concerning the second part, is whether a more sophisticated, decision-theoretic, Humean about the pro-attitudes can respond to the objections to (...) the simple Humean view, and whether Davidson was not in fact just such a sophisticated decision-theoretic Humean. RÉSUMÉ: Cet article pose deux questions sur le formidable livre de Robert Myers et Claudine Verheggen, Donald Davidson's Triangulation Argument: A Philosophical Inquiry. La première question, qui concerne la première partie du livre, consiste à déterminer si, étant donné la supposition qu'un individu solitaire ne peut pas avoir de contenus mentaux, nous pouvons démontrer qu'ajouter un autre individu ne permet pas de résoudre le problème. La seconde question, qui concerne la deuxième partie du livre, est de savoir si un tenant d'une conception humienne des pro-attitudes plus sophistiquée, adhérant à la théorie de la décision, peut répondre aux objections formulées contre la simple conception humienne, et si Davidson n’était pas en fait un tenant de ce second type de conception humienne.

Quine and Davidson employ proxy functions to demonstrate that the use of language (behaviouristically conceived) is compatible with indefinitely many radically different reference relations. They also believe that the use of language (behaviouristically conceived) is all that determines reference. From this they infer that reference is indeterminate, i.e. that there are no facts of the matter as to what singular terms designate and what predicates apply to. Yet referential indeterminacy yields rather dire consequences. One thus does wonder whether one can (...) hold on to a Quine--Davidson stance in semantics-cum-metaphysics and still avoid embracing referential indeterminacy. I argue that one can. Anyone adhering to the behaviouristic account pivotal to the Quine--Davidson stance is bound to acknowledge certain facts about verbal behaviour -- that some utterances are tied to situations, that some utterances are tied to segments in situations, that some predicates have non-contextualised conditions of application, and that use involves causal dependencies. The restrictions from these facts ensure that only reference relations generated by means of rather exceptional proxy functions are compatible with verbal behaviour. I conclude that this allows one to rebuff the Quine--Davidson argument for the indeterminacy of reference, as it were, from within. I moreover tentatively conclude that the line of thought laid out provides good reason for just about anyone to hold that there are facts about reference after all. (shrink)

The view that the brain is a sort of computer has functioned as a theoretical guideline both in cognitive science and, more recently, in neuroscience. But since we can view every physical system as a computer, it has been less than clear what this view amounts to. By considering in some detail a seminal study in computational neuroscience, I first suggest that neuroscientists invoke the computational outlook to explain regularities that are formulated in terms of the information content of electrical (...) signals. I then indicate why computational theories have explanatory force with respect to these regularities:in a nutshell, they underscore correspondence relations between formal/mathematical properties of the electrical signals and formal/mathematical properties of the represented objects. I finally link my proposal to the philosophical thesis that content plays an essential role in computational taxonomy. (shrink)

Turing does not provide an explanation for substituting the original question of his test – i.e., “Can machines think?” with “Can a machine pass the imitation game?” – resulting in an argumentative gap in his main thesis. In this article, I argue that a positive answer to the second question would mean attributing the ability of linguistic interactions to machines; while a positive answer to the original question would mean attributing the ability of thinking to machines. In such a situation, (...) defending the Turing Test requires establishing a relationship between thought and language. In this regard, Davidson's no-priority theory is presented as an approach for defending the test. (shrink)

I examine in detail the argument vaguely suggested by Davidson to the effect that holism entails the irreducibility of the mental. I defend this argument against two objections often made against arguments that attempt to derive metaphysical theses from premises that concern our ordinary criteria for applying terms. I appeal to two-dimensional semantics to explain the links between these criteria and issues about reference and reduction. I show how the irreducibility of the mental follows from the holistic and flexible character (...) of our criteria for attributing beliefs and intentional states. (shrink)

The Turing Test, originally proposed as a simple operational definition of intelligence, has now been with us for exactly half a century. It is safe to say that no other single article in computer science, and few other articles in science in general, have generated so much discussion. The present article chronicles the comments and controversy surrounding Turing's classic article from its publication to the present. The changing perception of the Turing Test over the last fifty years has paralleled the (...) changing attitudes in the scientific community towards artificial intelligence: from the unbridled optimism of 1960's to the current realization of the immense difficulties that still lie ahead. I conclude with the prediction that the Turing Test will remain important, not only as a landmark in the history of the development of intelligent machines, but also with real relevance to future generations of people living in a world in which the cognitive capacities of machines will be vastly greater than they are now.

Donald Davidson holds that intentional concepts are not reducible to physical or dispositional ones. This is due, he claims, to the constitutive role of normativity in the principles that govern the application of intentional concepts. According to Davidson, the specific way in which norms of rationality and coherence are mobilised by our interpretative principles sets mental concepts off from those of the natural sciences. I agree with Davidson on the irreducibility of the mental. However, I show that irreducibility is due (...) not to the normative character of intentional concepts, but to holism and the flexibility of interpretative principles. I then consider three arguments that Davidson has put forth to support the irreducibility of intentional properties on the basis of their normative character, and show that none of them goes through.

In 1950, Alan Turing proposed his eponymous test based on indistinguishability of verbal behavior as a replacement for the question "Can machines think?" Since then, two mutually contradictory but well-founded attitudes towards the Turing Test have arisen in the philosophical literature. On the one hand is the attitude that has become philosophical conventional wisdom, viz., that the Turing Test is hopelessly flawed as a sufficient condition for intelligence, while on the other hand is the overwhelming sense that were a machine (...) to pass a real live full-fledged Turing Test, it would be a sign of nothing but our orneriness to deny it the attribution of intelligence. The arguments against the sufficiency of the Turing Test for determining intelligence rely on showing that some extra conditions are logically necessary for intelligence beyond the behavioral properties exhibited by an agent under a Turing Test. Therefore, it cannot follow logically from passing a Turing Test that the agent is intelligent. I argue that these extra conditions can be revealed by the Turing Test, so long as we allow a very slight weakening of the criterion from one of logical proof to one of statistical proof under weak realizability assumptions. The argument depends on the notion of interactive proof developed in theoretical computer science, along with some simple physical facts that constrain the information capacity of agents. Crucially, the weakening is so slight as to make no conceivable difference from a practical standpoint. Thus, the Gordian knot between the two opposing views of the sufficiency of the Turing Test can be cut. (shrink)

This article explores the possibility of naturalized theory of action. It distinguishes ontological naturalism from conceptual naturalism, and asks whether a defensible theory of action can be either ontologically or conceptually naturalistic. The distinction between conditions for an ontology and conditions for a concept receives support from Donald Davidson's identification of two modes of explanation for action: rational and physical causal explanation. Davidson's action theory provides a naturalized ontology for action theory, but not a naturalized concept of intentional action. This (...) article raises doubts about Davidson's basis for such one-sided naturalism. It examines some conditions for a mode of explanation, in order to clarify whether an intentional mode of explanation might have ontological significance and thus raise problems for ontological naturalism. The article argues for the central role of certain instrumental factors in explanatory strategies, whether naturalistic or intentional; and it casts doubt on Jaegwon Kim's recent argument that intentional psychology and neuroscience are mutually exclusive as explanatory strategies. A key lesson is that variable end-dependent reasons are our only wherewithal in the evaluation of explanatory strategies. In this sense, our explanatory strategies are ultimately instrumental and perspectival. The article draws out the implications of this lesson for naturalized action theory and for psychological explanation. It opposes any suggested monopoly on explanation from the physical sciences.

The traditional Turing test appeals to an interrogator's judgement to determine whether or not their interlocutor is an intelligent agent. This paper argues that this kind of asymmetric experimental set-up is inappropriate for tracking a property such as intelligence because intelligence is grounded in part by symmetric relations of recognition between agents. In place, it proposes a reciprocal test which takes into account the judgments of both interrogators and competitors to determine if an agent is intelligent. This form of social (...) interaction better tracks both the evolution of natural intelligence and how the concept of intelligence is actually used within our society. This new test is defended against the criticisms that a proof of intelligence requires a demonstration of self-consciousness and that semantic externalism entails that a non-embodied Turing test is inadequate.

Alan Turing advocated a kind of functionalism: A machine M is a thinker provided that it responds in certain ways to certain inputs. Davidson argues that Turing’s functionalism is inconsistent with a cer-tain kind of epistemic externalism, and is therefore false. In Davidson’s view, concepts consist of causal liasons of a certain kind between subject and object. Turing’s machine doesn’t have the right kinds of causal li-asons to its environment. Therefore it doesn’t have concepts. Therefore it doesn’t think. I argue (...) that this reasoning is entirely fallacious. It is true that, in some cases, a causal liason between subject and object is part of one’s concept of that object. Consequently, to grasp certain propositions, one must have certain kids of causal ties to one’s environment. But this means that we must rethink some old views on what rationality is. It does not mean, pace Davidson, that a precondition for being rational is being causally embedded in one’s environment in a certain way. If Tur-ing’s machine isn’t capable of thinking (I leave it open whether it is or is not), that has nothing to do with its lacking certain kinds of causal con-nections to the environment. The larger significance of our discussion is this: rationality consists either in one’s ability to see the bearing of purely existential propositions on one another or rationality is simply not to be understood as the ability see the bearing that propositions have on one another.
