It is an old charge against Locke that his commitment to a common substratum for the observable qualities of particular objects and his empiricist theory about the origin of ideas are inconsistent with one another. How could we have an idea of something in which observable qualities inhere if all our ideas are constructed from ideas of observable qualities? In this paper, I propose an interpretation of the crucial passages in Locke, according to which the idea of substratum is formed (...) through an elaborate mental process which he calls “supposition.” It is the same process we use when we form the idea of infinity − another problematic idea for an empiricist. In the end, Locke was more liberal than most empiricists in subscribing to the existence of ideas far removed from experience, because he accepted supposition as a legitimate way of constructing new ideas.

On this, the 97th anniversary of the year of his birth, thoughts turn naturally to Willard Van Orman Quine. Quine, known as ‘Van’ to his friends but ‘That putz with the beret’ to everyone else, was one of the great systematists of the last century. The range of topics he addressed is awesome: epistemology, confirmation, philosophical logic, set theory, analyticity, modality, and, perhaps most familiarly, the indeterminacy of translation. My focus in this, my final and most challenging address as (...) Chair of the Department of Philosophy, will be on this last topic. (shrink)
Last year, as some of you may recall, I took it upon my chairly shoulders to solve the problem of causation, where this problem can be stated this way: What is causation? According to the analysis I offered, C is a cause of E if and only if C makes E happen. I am happy to report that, in the year since delivering this account of causation, no objections have arisen. The critics have been silenced. Indeed, my colleague Dan Hausman, (...) the Herbert Simon Professor of Philosophy, reports that he is no longer satisfied with the view he expressed in his recent book on causation, and I have no doubt that his change of mind is due in no small part to my seminal contribution to this subject. If you would permit me a joke, I think I “made happen” a change in Dan’s mind. I should also mention that we are now fortunate to have amongst us Carolina Sartorio, whose own analysis of causation, arrived at independently (she claims), seems but a stylistic variant of my own. Where I see causes as things that make things happen, she sees them as things that make a difference. I think, but can’t be certain, that our analyses come to the same thing. Perhaps if she hadn’t muddied the waters with all those numbered propositions and ‘ifs’ and ‘thens’ we could settle the matter. (shrink)
A central controversy in philosophy of psychology pits reductionists against, for lack of a better term, autonomists. The reductionist’s burden is to show that psychology is, at best, merely a heuristic device for describing phenomena that are, when speaking more precisely, just physical. I say “at best,” because reductionists are prone to less conciliatory remarks, such as: “psychological property P just is physical property N, so scientific explanation might as well focus exclusively on N,” and “psychological property P is nothing (...) other than N, so generalizations about N suffice to say all that there is to say about P,” and “knowledge of all the N facts suffices for knowledge of all the P facts.”.

Within a decade or so following publication of Barkow, Cosmides and Tooby’s landmark book The Adapted Mind: Evolutionary Psychology and the Generation of Culture (1992), evolutionary psychology had bulldozed its way into the public eye. Its topics were sexy, and not just figuratively. Among them were questions about why men prefer nubile women with large breasts, why women prefer broad-chested men who drive fancy automobiles, why men view sexual infidelity as more serious than emotional infidelity while women show the opposite (...) pattern, why people view incest with revulsion. Evolutionary psychologists also sought to explain why stepfathers abuse their stepchildren more often than their biological children, and why rules of reasoning, such as material implication, are easier to apply when trying to spot a cheater than when deciding whether an odd number would be on one side of a card if a vowel was on the other. And while there were critics (e.g. Stephen Gould, ‘‘Evolution: The Pleasures of Pluralism’’, 1997), evolutionary psychology had built a head of steam and its shibboleths soon became the darlings of the popular media. Of course men prefer nubile women: natural selection would have eliminated men who chose to mate with females too young or old to bear children. Obviously women prefer high status males – women who preferred mates who could not provide for their children would not have spread their genes beyond the next generation. And what else but natural selection could explain why people react with disgust to incest? The most significant bump in the road for evolutionary psychology arose with the publication of David Buller’s exhaustive critique.. (shrink)
In this paper today, I would like to offer a new analysis of causation and of causal claims. It is an unorthodox one, as you will see, but I suspect that in the not too distant future it will be seen as intuitively, perhaps even trivially, true. I hardly need defend the urgency of my project. Ever since Hume, philosophers have wondered whether there are causes. This is a desperate situation. With no causes, it's hard to see how brushing my (...) teeth is likely to prevent tooth decay. Indeed, it would not be unreasonable to read Hume as an advocate of rotten teeth, which might explain the sad state that many British mouths find themselves in today. The attentive listener will have noted that I said Hume's advocacy of rotten teeth might explain the abysmal state of British oral hygiene. Of course, if Hume is right about causation then nothing explains anything, and that explains why I have been tentative in my claim. The account I would like to propose is this. The claim ‘x causes y’ is to be understood in the following way: ‘x makes y happen’. That is, to say that x is the cause of y is just to say that x makes y happen. Or, to put it more succinctly, if x is the cause of y, then x makes y happen. This is no doubt a startling claim, and one in need of further clarification and defense. To begin, I should like to contrast my analysis with another that might, on its surface, appear similar. Suppose one were to claim that 'x is the cause of y' means that x brings y about. But ‘bringing about’ is hardly an informative verbal clause, and does little ampliative work. This way of putting it lacks the opaque transparency that we’ve come to expect of philosophical analyses of causation. Now this new account is not necessarily inconsistent with other, more traditional analyses, such as Lewis and Hausman's analyses of causation in terms of counterfactuals or Eells' probabilistic theory of causation. Consider first counterfactual analyses of causation. These are efforts to account for the meaning of causal dependencies.. (shrink)
In every philosopher’s career, there comes a time to look back on accomplishments, assess achievements, evaluate one’s place in a canon that dates to an era when Ancient Greeks still roamed the Earth. Perhaps many of you have wondered when I’d finally get around to doing this. Sadly, this is not the night for that splendid occasion. Do not pretend to hide your disappointment. Also, do not hesitate to point fingers. Believe me when I tell you that I would take (...) great delight in reporting to you my accomplishments, achievements, and place in the canon. If you don’t believe me, ask anyone who knows me well, or, at any rate, has spent a few minutes in conversation with me, or, maybe, has simply observed me in conversation with someone else. They’ll tell you that I am uniquely suited to fete myself, and take obvious pleasure spreading the good word to others. Alas, I have been enlisted to concentrate my philosophical powers on a topic less interesting than myself. My focus? A woman named Ruth Millikan. For philosophers, mention of the Book of Ruth directs thoughts not to the Old Testament, but to LTOBC. This is a shame, because Ruth’s Old Testament book is quite short, as books go, and tells a heartwarming story of redemption and devotion – virtues that receive hardly any mention in LTOBC. Now that I think about it, Ruth’s later books and articles mark a significant departure from the plot line in that first Book of Ruth’s. Gone are references to Bethlehem and Moab, and in their place lurk hoverflies and push me pull yous, but more on these matters in a moment. I want first to turn my finely tuned and oft picked philosophical nose to LTOBC – unquestionably Professor Millikan’s magnum opus . Here’s a little known fact. Originally, LTOBC had a different title, requiring a different acronym. If she hadn’t taken her editor’s advice, we’d be speaking of BLTOBC, which stood for Bacon, Lettuce, and Tomato on Blueberry Cobbler. There’s something down home and grannyish about this title, and Ruth deserves credit for trying to entice readers with the promise of good old fashioned, feather plucked, farm food, but, as her editor was quick to note, bacon, lettuce, and tomato have no more place on blueberry cobbler than they do on cherry cobbler, and so BLTOBC might as well be BLTOCC, and with no reason to prefer one title to the other, best just to forget about the bacon..

The revisionary approach to semantic paradox is commonly thought to have a somewhat uncomfortable corollary, viz. that, on pain of triviality, we cannot affirm that all valid arguments preserve truth (Beall2007, Beall2009, Field2008, Field2009). We show that the standard arguments for this conclusion all break down once (i) the structural rule of contraction is restricted and (ii) how the premises can be aggregated---so that they can be said to jointly entail a given conclusion---is appropriately understood. In addition, we briefly rehearse (...) some reasons for restricting structural contraction. (shrink)
When philosophers defend epiphenomenalist doctrines, they often do so by way of a priori arguments. Here we suggest an empirical approach that is modeled on August Weismann.
This paper examines the pressures leading two very different Early Modern philosophers, Descartes and Locke, to invoke two ways in which thought is directed at objects. According to both philosophers, I argue, the same idea can simultaneously count as “of” two different objects—in two different senses of the phrase ‘idea of’. One kind of intentional directedness is invoked in answering the question What is it to think that thus-and-so? The other kind is invoked in answering the question What accounts for (...) the success of our proper methods of inquiry? For Descartes as well as Locke, the two kinds of “ofness” come apart as a result of strong rationalist commitments. However, I will suggest that even if we reject such commitments, we go wrong if we assume that a single kind of intentional directedness suffices to address both questions. (shrink)
: McDowell opposes the view that the intentionality of language and thought remains mysterious unless it can be understood ‘from outside the conceptual order’. While he thinks the demand for such a ‘sideways-on’ understanding can be the result of ‘scientistic prejudice’, he points to Sellars's thought as exhibiting a different source: a distortion of our perspective ‘from within the conceptual order’. The distortion involves a failure on Sellars's part to see how descriptions from within the conceptual order can present expressions (...) and mental acts as related to extra-conceptual objects (a failure in turn explained by his failure to see how such relations could have normative import). In this paper, I argue that Sellars's thought suffers from no such distortion. If that is right, McDowell's examination of Sellars has not uncovered a disorder whose treatment might help relieve the desire for a sideways-on view. (shrink)
A statement of the form ‘C caused E’ obeys the requirement of proportionality precisely when C says no more than what is necessary to bring about E. The thesis that causal statements must obey this requirement might be given a semantic or a pragmatic justification. We use the idea that causal claims are contrastive to criticize both.
It is generally assumed that Descartes invokes “objective being in the intellect” in order to explain or describe an idea’s status as being “of something.” I argue that this assumption is mistaken. As emerges in his discussion of “materially false ideas” in the Fourth Replies, Descartes recognizes two senses of ‘idea of’. One, a theoretical sense, is itself introduced in terms of objective being. Hence Descartes can’t be introducing objective being to explain or describe “ofness” understood in this sense. Descartes (...) also appeals to a pretheoretical sense of ‘idea of’. I will argue that the notion of objective being can’t serve to explain or describe this “ofness” either. I conclude by proposing an alternative explanation of the role of objective being, according to which Descartes introduces this notion to explain the mind’s ability to attain clear and distinct ideas.

Christian List and Peter Menzies 2009 have looked to interventionist theories of causation for an answer to Jaegwon Kim's causal exclusion problem. Important to their response is the idea of realization-insensitivity. However, this idea becomes mired in issues concerning multiple realization, leaving it unable to fulfil its promise to block exclusion. After explaining why realization-insensitivity fails as a solution to Kim's problem, I look to interventionism to describe a different kind of solution.
Deflationists about truth seek to undermine debates about the nature of truth by arguing that the truth predicate is merely a device that allows us to express a certain kind of generality. I argue that a parallel approach is available in the case of logical consequence. Just as deflationism about truth offers an alternative to accounts of truth's nature in terms of correspondence or justification, deflationism about consequence promises an alternative to model-theoretic or proof-theoretic accounts of consequence's nature. I then (...) argue, against considerations put forward by Field and Beall, that Curry's paradox no more rules out deflationism about consequence than the liar paradox rules out deflationism about truth.

There is a standard objection against purported explanations of how a language L can express the notion of being a true sentence of L. According to this objection, such explanations avoid one paradox (the Liar) only to succumb to another of the same kind. Even if L can contain its own truth predicate, we can identify another notion it cannot express, on pain of contradiction via Liar-like reasoning. This paper seeks to undermine such ‘revenge’ by arguing that it presupposes a (...) dubious assumption about the linguistic expression of concepts. Successful revenge would require that there be a notion other than truth that plays the same role with respect to concept-expression that truth is naturally thought to play before we are confronted with the Liar paradox.

Jaegwon Kim’s causal exclusion argument has rarely been evaluated from an empirical perspective. This is puzzling because its conclusion seems to be making a testable claim about the world: supervenient properties are causally inefficacious. An empirical perspective, however, reveals Kim’s argument to rest on a mistaken conception about how to test whether a property is causally efficacious. Moreover, the empirical perspective makes visible a metaphysical bias that Kim brings to his argument that involves a principle of non-inclusion.
Prominent defenders of the extended cognition thesis have looked to evolutionary theory for support. Roughly, the idea is that natural selection leads one to expect that cognitive strategies should exploit the environment, and exploitation of the right sort results in a cognitive system that extends beyond the head of the organism. I argue that proper appreciation of evolutionary theory should create no such expectation. This leaves open whether cognitive systems might in fact bear a relationship to the environment that leads (...) to their extension. *Received July 2009; revised January 2010. †To contact the author, please write to: Department of Philosophy, 5185 Helen C.

Ideas play at least two roles in Locke's theory of the understanding. They are constituents of ‘propositions,’ and some of them ‘represent’ the qualities and sorts of surrounding bodies. I argue that each role involves a distinct kind of intentional directedness. The same idea will in general be an ‘idea of’ two different objects, in different senses of the expression. Identifying Locke's scheme of twofold ‘ofness’ reveals a common structure to his accounts of simple ideas and complex ideas of substances. (...) A consequence is a distinction among substance sorts parallel to one of his distinctions between primary and secondary qualities. (shrink)
The discovery of mirror neurons has been hailed as one of the most exciting developments in neuroscience in the past few decades. These neurons discharge in response to the observation of others’ actions. But how are we to understand the function of these neurons? In this paper I defend the idea that mirror neurons are best conceived as components of a sensory system that has the function to perceive action. In short, mirror neurons are part of a hitherto unrecognized “sixth (...) sense”. In this spirit, research should move toward developing a psychophysics of mirror neurons. (shrink)
Andy Clark's Supersizing the Mind begins as a manifesto in which the components of an embodied theory of mind are carefully moved into place, proceeds to a defense of these components from recent critical attacks, and ends with words of caution to those who would seek to extract too much from the embodied perspective. Readers unfamiliar with Clark's earlier works are likely to find the result dazzling -- an exciting, novel, and coherent conception of the mind that dares one to (...) abandon nearly every vestige of a comfortably Cartesian view of mind. Of course, philosophers of mind have, for the most part, already jettisoned the idea that minds are an ethereal sort of non-physical substance. We can now assert with no great temerity that Descartes was wrong about that. Even so, one might still agree with Descartes that minds are in some sense distinct from bodies. They are, as it were, in the head. Yet, if Clark's case for embodiment is on track, minds are not in the head. The supervenience base for a mind (and not simply mental content) can include pieces of the extracranial body and, indeed, objects in the world beyond. (shrink)
Carl Gillett has defended what he calls the “dimensioned” view of the realization relation, which he contrasts with the traditional “flat” view of realization (2003, 2007; see also Gillett 2002). Intuitively, the dimensioned approach characterizes realization in terms of composition whereas the flat approach views realization in terms of occupiers of functional roles. Elsewhere we have argued that the general view of realization and multiple realization that Gillett advances is not able to discharge the theoretical duties of those relations (Shapiro (...) 2004, unpublished manuscript; Polger 2004, 2007, forthcoming). Here we focus on an internal objection to Gillett’s account and then raise some broader reasons to reject it. (shrink)

When conceived as an empirical claim, it is natural to wonder how one might test the hypothesis of multiple realization. I consider general issues of testability, show how they apply specifically to the hypothesis of multiple realization, and propose an auxiliary assumption that, I argue, must be conjoined to the hypothesis of multiple realization to ensure its testability. I argue further that Bechtel and Mundale (1999) go astray because they fail to appreciate the need for this auxiliary assumption. †To (...) contact the author, please write to: Department of Philosophy, University of Wisconsin–Madison, 5185 Helen C.

Critics of attempts to explain meaning in terms of truth-conditions have tended to charge their opponents with misconceptions regarding truth. I shall argue that the 'naïve' version of the truth-conditional theory which best accounts for its resilience fails for a different and more basic reason, namely, circularity arising from the contingency of meaning. One reason why this problem has been overlooked is a tendency (noted by Dummett in a different connection) to assimilate the naïve truth-conditional theory to an idealized verificationism.

Embodied Cognition is an approach to cognition that departs from traditional cognitive science in its reluctance to conceive of cognition as computational and in its emphasis on the significance of an organism’s body in how and what the organism thinks. Three lines of embodied cognition research are described and some thoughts on the future of embodied cognition offered.
Unifying traditional cognitive science is the idea that thinking is a process of symbol manipulation, where symbols lead both a syntactic and a semantic life. The syntax of a symbol comprises those properties in virtue of which the symbol undergoes rule-dictated transformations. The semantics of a symbol constitute the symbolsÕ meaning or representational content. Thought consists in the syntactically determined manipulation of symbols, but in a way that respects their semantics. Thus, for instance, a calculating computer sensitive only to the (...) shape of symbols might produce the symbol Ô5Õ in response to the inputs Ô2Õ, Ô+Õ, and Ô3Õ. As far as the computer is concerned, these symbols have no meaning, but because of its program it will produce outputs that, to the user, Òmake senseÓ given the meanings the user attributes to the symbols.

According to Gupta and Belnap, the “extensional behavior” of ‘true’ matches that of a circularly defined predicate. Besides promising to explain semantic paradoxicality, their general theory of circular predicates significantly liberalizes the framework of truth-conditional semantics. The authors’ discussions of the rationale behind that liberalization invoke two distinct senses in which a circular predicate’s semantic behavior is explained by a “revision rule” carrying hypothetical information about its extension. Neither attempted explanation succeeds. Their theory may however be modified to employ a (...) relativized notion of extension. The resulting contextualist semantics for ‘true’ construes circularity as a pragmatic phenomenon. (shrink)
Jaegwon Kim has argued that if psychological kinds are multiply realizable then no single psychological theory can describe regularities ranging over psychological states. Instead, psychology must be fractured, with human psychology covering states realized in the human way, martian psychology covering states realized in the martian way, and so on. I show that even if one accepts the principles that motivate Kim’s argument, his conclusion does not follow. I then offer a dilemma that forces Kim to concede the possibility of (...) a unified psychology. I close with a discussion of what, according to Jerry Fodor, is “really bugging” Kim. (shrink)

Shapiro tests these hypotheses against two rivals, the mental constraint thesis and the embodied mind thesis. Collecting evidence from a variety of sources (e.g., neuroscience, evolutionary theory, and embodied cognition) he concludes that the multiple realizability thesis, accepted by most philosophers as a virtual truism, is much less obvious than commonly assumed, and that there is even stronger reason to give up the separability thesis. In contrast to views of mind that tempt us to see the mind as simply being (...) resident in a brain or body, Shapiro argues for a far more encompassing integration of mind, brain, and body than philosophers have supposed.

Brandom's "inferentialism"—his theory that contentfulness consists in being governed by inferential norms—proves dubiously compatible with his own deflationary approach to intentional objectivity. This is because a deflationist argument, adapted from the case of truth to that of correct inference, undermines the criterion of adequacy Brandom employs in motivating inferentialism. Once that constraint is abandoned, moreover, the very constitutive-explanatory availability of Brandom's inferential norms becomes suspect. Yet Brandom intertwines inferentialism with a separate explanatory project, one that in explaining the pragmatic significance (...) of meaning-attributions does yield a convincing construal of the claim that the concept of meaning is normative.

In a remarkable series of Critical-period Reflexionen (5611-4, 5616-9), Kant sketches a defense of the possibility of freedom that differs radically from his usual compatibilism by incorporating an indeterministic account of the phenomena. Anticipating Łukasiewicz, Kant reconciles universal causal determination with an open future by positing a lower temporal bound for the infinite regress of prior determining causes issuing in a contingent action. On this account, Kant however concedes, the unity of experience "cannot fully obtain in the case of free (...) beings." The fact that Kant even contemplated the indeterministic theory may carry implications for interpreting the Second Analogy. (shrink)
Ketelaar and Ellis have provided a remarkably clear and succinct statement of Lakatosian philosophy of science and have also argued compellingly that the neo-Darwinian theory of evolution fills the Lakatosian criteria of progressivity. We find ourselves in agreement with much of what Ketelaar and Ellis say about Lakatosian philosophy of science, but have some questions about (1) the place of evolutionary psychology in a Lakatosian framework, and (2) the extent to which evolutionary psychology truly predicts new findings.
Locke's claims about the "inadequacy" of substance-ideas can only be understood once it is recognized that the "sort" represented by such an idea is not wholly determined by the idea's descriptive content. The key to his compromise between classificatory conventionalism and essentialism is his injunction to "perfect" the abstract ideas that serve as "nominal essences." This injunction promotes the pursuit of collections of perceptible qualities that approach ever closer to singling out things that possess some shared explanatory-level constitution. It is (...) in view of this norm regulating natural-historical inquiry that a substance-idea represents a sort for which some such constitution serves as the "real essence," i.e. as that on which all the sort's characteristic "properties" depend.

Quite unexpectedly, cognitive psychologists find their field intimately connected to a whole new intellectual landscape that had previously seemed remote, unfamiliar, and all but irrelevant. Yet the proliferating connections tying together the cognitive and evolutionary communities promise to transform both fields, with each supplying necessary principles, methods, and a species of rigor that the other lacks.

Frances Egan argues that the states of computational theories of vision are individuated individualistically and, as far as the theory is concerned, are not intentional. Her argument depends on equating the goals and explanatory strategies of computational psychology with those of its algorithmic level. However, closer inspection of computational psychology reveals that the computational level plays an essential role in explaining visual processes and that explanations at this level are nonindividualistic and intentional. In conclusion, I sketch an account of content (...) in which content does the sort of explanatory work that Egan denies is possible. (shrink)
Many philosophers and psychologists who approach the issue of representation from a computational or measurement theoretical perspective end up having to deny the possibility of junk representations?representations present in an organism's head but that enter into no psychological processes or produce no behaviour. However, I argue, a more functional perspective makes the possibility of junk representations intuitively quite plausible?so much so that we may wish to question those views of representation that preclude the possibility of junk representations. I explore some (...) of the reasons we should care about the possibility of junk representations and conclude with some speculation about whether junk representations are in fact present in our heads.

While there is controversy over which of several naturalistic theories of the mental is most plausible, there is consensus regarding the desideratum of a naturalistically respectable theory. A naturalistic theory of the mental, it is agreed, must explicate representation in nonintentional terms. I argue that this constraint does not get at the heart of what it is to be natural. On the one hand, it fails to provide us with a meaningful distinction between the natural and the unnatural. On the (...) other hand, it unfairly suggests that we withhold judgment on those successes our sciences of the mind have already achieved until a convincing decomposition of the mental is available. I urge a new conception of naturalism that focuses less upon ontological considerations and more upon methodological ones. (shrink)
Since the founding of psychophysics in the latter half of the nineteenth century, controversy has raged over the subject matter of psychophysical laws. Originally, Fechner characterized psycho physics as the science describing the relation between physical magnitudes and the sensations these magnitudes produce in us. Today many psycho-physicists would deny that sensation is or could be a topic of psycho-physical investigation. I consider Savage's (1970) influential objections to the possibility of such an investigation and argue that they depend upon (i) (...) holding psychophysics to higher standards than those to which we hold other sciences; and (ii) misrepresenting Fechner's stated goals for psychophysics.

Reichenbach's Philosophy of Space and Time (1928) avoids most of the logical positivist pitfalls it is generally held to exemplify, notably both conventionalism and verificationism. To see why, we must appreciate that Reichenbach's interest lies in how mathematical structures can be used to describe reality, not in how words like 'distance' acquire meaning. Examination of his proposed "coordinative definition" of congruence shows that Reichenbach advocates a reductionist analysis of the relations figuring in physical geometry (contrary to common readings that attribute (...) to him a holistic conventionalism), while embracing a thoroughly holistic understanding of empirical confirmation (contrary to rival operationalist readings).

Fodor (1990) argues that the theory of evolution by natural selection will not help to save naturalistic accounts of representation from the disjunction problem. This is because, he claims, the context 'was selected for representing things as F' is transparent to the substitution of predicates coextensive with F. But, I respond, from an evolutionary perspective representational contexts cannot be transparent: only under particular descriptions will a representational state appear as a "solution" to a selection "problem" and so be adaptive. Only (...) when we construe representational states as opaque in this manner are the generalizations of branches of evolutionary theory, like foraging theory, possible. (shrink)
