Abstract: On a literal reading of `Computing Machinery and Intelligence'', Alan Turing presented not one, but two, practical tests to replace the question `Can machines think?'' He presented them as equivalent. I show here that the first test described in that much-discussed paper is in fact not equivalent to the second one, which has since become known as `the Turing Test''. The two tests can yield different results; it is the first, neglected test that provides the more appropriate indication of intelligence. This is because the features of intelligence upon which it relies are resourcefulness and a critical attitude to one''s habitual responses; thus the test''s applicablity is not restricted to any particular species, nor does it presume any particular capacities. This is more appropriate because the question under consideration is what would count as machine intelligence. The first test realizes a possibility that philosophers have overlooked: a test that uses a human''s linguistic performance in setting an empirical test of intelligence, but does not make behavioral similarity to that performance the criterion of intelligence. Consequently, the first test is immune to many of the philosophical criticisms on the basis of which the (so-called) `Turing Test'' has been dismissed.

Abstract: A common argument against explanatory reductionism is that higher-level explanations are sometimes or always preferable because they are more general than reductive explanations. Here I challenge two basic assumptions that are needed for that argument to succeed. It cannot be assumed that higher-level explanations are more general than their lower-level alternatives or that higher-level explanations are general in the right way to be explanatory. I suggest a novel form of pluralism regarding levels of explanation, according to which explanations at different levels are preferable in different circumstances because they offer different types of generality, which are appropriate in different circumstances of explanation.

Abstract: It has recently been argued that the success of the connectionist program in cognitive science would threaten folk psychology. I articulate and defend a "minimalist" construal of folk psychology that comports well with empirical evidence on the folk understanding of belief and is compatible with even the most radical developments in cognitive science.

Abstract: The computational theory of mind construes the mind as an information-processor and cognitive capacities as essentially representational capacities. Proponents of the view claim a central role for representational content in computational models of these capacities. In this paper I argue that the standard view of the role of representational content in computational models is mistaken; I argue that representational content is to be understood as a gloss on the computational characterization of a cognitive process.

Abstract: Representationalism, in its most widely accepted form, is the view that the human mind is an information-using system, and that human cognitive capacities are to be understood as representational capacities. This chapter distinguishes several distinct theses that go by the name "representationalism," focusing on the view that is most prevalent in cogntive science. It also discusses some objections to the view and attempts to clarify the role that representational content plays in cognitive models that make use of the notion of representation.

Abstract: The claim of the multiple realizability of mental states by brain states has been a major feature of the dominant philosophy of mind of the late 20th century. The claim is usually motivated by evidence that mental states are multiply realized, both within humans and between humans and other species. We challenge this contention by focusing on how neuroscientists differentiate brain areas. The fact that they rely centrally on psychological measures in mapping the brain and do so in a comparative fashion undercuts the likelihood that, at least within organic life forms, we are likely to find cases of multiply realized psychological functions.

Abstract: Philosophers and psychologists have often maintained that in order to attribute mental states to other people one must have a 'theory of mind'. This theory facilitates our grasp of other people's mental states. Debate has then focussed on the form this theory should take. Recently a new approach has been suggested, which I call the 'Direct Perception approach to social cognition'. This approach maintains that we can directly perceive other people's mental states. It opposes traditional views on two counts: by claiming that mental states are observable and by claiming that we can attribute them to others without the need for a theory of mind. This paper argues that there are two readings of the direct perception claims: a strong and a weak one. The Theory-theory is compatible with the weak version but not the strong one. The paper argues that the strong version of direct perception is untenable, drawing on evidence from the mirror neuron literature and arguments from the philosophy of science and perception to support this claim. It suggests that one traditional 'theory of mind' view, the 'Theory-theory' view, is compatible with the claim that mental states are observable, and concludes that direct perception views do not offer a viable alternative to theory of mind approaches to social cognition.

Summary: This lucid and wide-ranging volume constitutes a self-contained introduction to the elements and key issues of the philosophy of language. In particular, it focuses on the philosophical foundations of semantics, including the main challenges to and prospects for a truth conditional semantics. Since the book is neither single-mindedly philosophical, nor single-mindedly technical, it is an accessible introduction to the philosophical foundations of semantics, and will provide the ideal basis for a first course in the philosophy of language and philosophical logic.

Abstract: This paper examines and rejects some purported refutations of eliminative materialism in the philosophy of mind: a quasi-transcendental argument due to Jackson and Pettit (1990) to the effect that folk psychology is "peculiarly unlikely" to be radically revised or eliminated in light of the developments of cognitive science and neuroscience; and (b) certain straight-out transcendental arguments to the effect that eliminativism is somehow incoherent (Baker, 1987; Boghossian, 1990). It begins by clarifying the exact topology of the dialectical space in which debates between eliminativist and anti-eliminativist ought to be framed. I claim that both proponents and opponents of eliminativism have been insufficiently attentive to the range of dialectical possibilities. Consequently, the debate has not, in fact, been framed within the correct dialectical setting. I then go onto to show how inattentiveness to the range of dialectical possibilities undermines both transcendental and quasi-transcendental arguments against eliminativism. In particular, I argue that the quasi-transcendentalist overestimates the degree to which folk psychology can be insulated from the advance of neuroscience and cognitive science just in virtue of being a functional theory. I argue further that transcendental arguments are fallacious and do not succeed against even the strongest possible form of eliminativism. Finally, I argue that that transcendental arguments are irrelevant. Even if such arguments do succeed against a certain'very strong form of eliminativism, they remain complete non-starters against certain weaker forms of eliminativism. And I argue that if any of these weaker forms is true, folk psychology is in trouble enough to vindicate Paul Ckurchland's claim that our common sense psychological framework is "a radically false and misleading conception of the causes of human behavior and the nature of cognitive activity".

Summary: Narrow content functionalism claims that the contents of beliefs are determined by their causal profile. If two belief tokens are of the same causal type, they are of the same semantic type. However, Taylor argues that de dicto semantic types do not supervene on causal types, due to multiple realizability. He establishes this with the thought experiment of "fraternal twin earth", where things are functionally identical but molecularily different.
