Realism,Positivism and Reference

Summary  Depending on the realist or instrumentalist twist that is given to positivism, interesting arguments can be made for both causal and classical theories of reference with regard to the use of scientific terms in the language of theory. But my claim is that the rigid foundationalism that supports the theoretical terms via the correspondence rules of the Received View undercuts the notion that it is possible to argue coherently for a causal theory of reference as allied to a positivistic view.     

What Can Causal Claims Mean?

How can Hume account for the meaning of causal claims? The causal realist, I argue, is, on Hume's view, saying something nonsensical. I argue that both realist and agnostic interpretations of Hume are inconsistent with his view of language and intentionality. But what then accounts for this illusion of meaning? And even when we use causal terms in accordance with Hume’s definitions, we seem merely to be making disguised self-reports. I argue that Hume’s view is not as implausible as it sounds by exploring his conception of language.     

In support of content theories of art

A standard view of reference holds that a speaker's use of a name refers to a certain thing in virtue of the speaker's associating a condition with that use that singles the referent out. This view has been criticized by Saul Kripke as empirically inadequate. Recently, however, it has been argued that a version of the standard view, a response-based theory of reference, survives the charge of empirical inadequacy by allowing that associated conditions may be largely or even entirely implicit. This paper argues that response-based theories of reference are prey to a variant of the empirical inadequacy objection, because they are ill-suited to accommodate the successful use of proper names by pre-school children. Further, I argue that there is reason to believe that normal adults are, by and large, no different from children with respect to how the referents of their names are determined. I conclude that speakers typically refer positionally: the referent of a use of a proper name is typically determined by aspects of the speaker's position, rather than by associated conditions present, however implicitly, in her psychology.     

O’Connor’s argument for indeterminism

Timothy O’Connor has recently defended a version of libertarianism that has significant advantages over similar accounts. One of these is an argument that secures indeterminism on the basis of an argument that shows how causal determinism threatens agency in virtue of the nature of the causal relation involved in free acts. In this paper, I argue that while it does turn out that free acts are not causally determined on O’Connor’s view, this fact is merely stipulative and the argument that he presents for this conclusion begs the question.     

A Dilemma for Calibrationism

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution.     

Philosophy, Solipsism and Thought

Wittgenstein's view of philosophy in the Tractatus presupposes that thought may be revealed without remainder in the use of signs. It is commonly held, however, that in the Tractatus he treated thought as logically prior to language. If this view, expressed most lucidly by Norman Malcolm, were correct, Wittgenstein would be inconsistent in holding that thought can be revealed without remainder in the use of signs. I argue that this is not correct. Thought may be prior to language in time but not in logic , for non-verbal symbols must have a logical structure in common with verbal ones. A view comparable with Malcolm's holds that Wittgenstein, under the influence of Schopenhauer, is committed to some form of solipsism. I argue that neither Schopenhauer nor Wittgenstein held any version of solipsism. For both philosophers, subject and object are correlative, so that it is incoherent to affirm the existence of the one without presupposing the existence of the other.     

The location problem for color subjectivism

According to color subjectivism, colors are mental properties, processes, or events of visual experiences of color. I first lay out an argument for subjectivism founded on claims from visual science and show that it also relies on a philosophical assumption. I then argue that subjectivism is untenable because this view cannot provide a plausible account of color perception. I describe three versions of subjectivism, each of which combines subjectivism with a theory of perception, namely sense datum theory, adverbialism, and the virtual color proposal, and argue that each version faces serious objections. Considering these three theories of perception to be exhaustive of those available to the subjectivist, I conclude that subjectivism is untenable and that the scientifically motivated argument for this view is unsound. I then offer the diagnosis that the philosophical assumption on which this argument relies is mistaken.     

The defeater version of Benacerraf’s problem for a priori knowledge

Paul Benacerraf’s argument that mathematical realism is apparently incompatible with mathematical knowledge has been widely thought to also show that a priori knowledge in general is problematic. Although many philosophers have rejected Benacerraf’s argument because it assumes a causal theory of knowledge, some maintain that Benacerraf nevertheless put his finger on a genuine problem, even though he didn’t state the problem in its most challenging form. After diagnosing what went wrong with Benacerraf’s argument, I argue that a new, more challenging, version of Benacerraf’s problem can be constructed. The new version—what I call the Defeater Version—of Benacerraf’s problem makes use of a no-defeater condition on knowledge and justification. I conclude by arguing that the best way to avoid the problem is to construct a theory of how a priori judgments reliably track the facts. I also suggest four different kinds of theories worth pursuing.     

Depicting Depictions

How is it possible for a picture to depict a picture? Proponents of perceptual theories of depiction, who argue that the content of a picture is determined, in part, by the visual state it elicits in suitable viewers, that is, by a state of seeing‐in, have given a plausible answer to this question. They say that a picture depicts a picture, in part, because, under appropriate conditions of observation, a suitable viewer will be able to see a picture in the picture. In this article, I first argue that this answer is in conflict with the way in which some of the most influential perceptual theories of depiction – Robert Hopkins's version of the experienced resemblance theory and Dominic Lopes's version of the recognition theory – construe seeing‐in. I then formulate a version of the recognition theory that avoids this conflict and show how it can explain the depiction of pictures.     

Causal Projectivism,Agency, and Objectivity

This article examines how specific realist and projectivist versions of manipulability theories of causation deal with the problem of objectivity. Does an agent-dependent concept of manipulability (i.e. the agency theory version of causal projectivism) imply that conflicting causal claims made by agents with different capacities can come out as true? In defence of the projectivist stance taken by the agency view, I argue that if the agent’s perspective is shown to be uniform across different agents, then the truth-values of causal claims do not vary arbitrarily and, thus, reach a satisfactory level of objectivity. My argument connects Price’s considerations on the situation of deliberation, whose structure, common to all agents, is the same with respect to both decision making and causal claims on a concept inspired by Douglas’s classification of objectivity of thought processes: the perspective of the detached agent. I further argue that, despite his agent-independent concept of intervention, Woodward’s claim of a stronger objectivity standard (i.e. agent independence) cannot be achieved, as the relativity of causal concepts to a variable set brings about the issue of the agent’s choice of variables. Consequently, a more permissive objectivity standard (admitting of the agent’s perspective) applies to both views.     

Causality and things in themselves

In this paper I examine Kant's use of causal language to characterize things in themselves. Following Nicholas Rescher, I contend that Kant's use of such causal language can only be understood by first coming to grips with the relation of things in themselves to appearances. Unlike Rescher, however, I argue that things in themselves and appearances are not numerically distinct entities. Rather, I claim that it is things in themselves that we are intentionally related to in veridical experience, though of course we know them only as they appear to us via our subjective experiential faculties. In light of this account of the role of things in themselves in Kant's account of experience, I argue that his use of causal locutions to describe things in themselves is simply his attempt to capture the fact that as the objects that we are related to in experience, the existence of things in themselves is presupposed by any account of the nature of our experienceof them.Substantial work on this paper was done while I attended the National Endowment for the Humanities 1986 Summer Seminar given by Hector-Neri Castañeda at Indiana University. I would like to thank the National Endowment for the Humanities for their support, and Professor Castañeda and the other members of the seminar for their many invaluable comments, suggestions, and criticisms.     

Horwich on meaning and use

Paul Horwich claims that theories of meaning ought to accommodate the commonsense intuition that meanings play a part in explaining the use of words. Further, he argues that the view that best does so is that according to which the meaning of a word is constituted by a disposition to accept, in some circumstances, sentences in which it features. I argue that if meanings are construed thus, they will in fact fail to explain the use of words. I also argue that if we insist, as Horwich does, on the commonsense assumption that meanings are a species of entity, all versions of the view that meaning is constituted by our dispositions to use words will have to be rejected. I do not, however, claim that such theories ought to be rejected. My point is that they are incompatible with the requirements of commonsense. Further, I suggest that it is premature to impose such requirements on theories of meaning.     

Practical success and the nature of truth

Philip Kitcher has argued for a causal correspondence view of truth, as against a deflationary view, on the grounds that the former is better poised than the latter to explain systematically successful patterns of action. Though Kitcher is right to focus on systematically successful action, rather than singular practical successes, he is wrong to conclude that causal correspondence theories are capable of explaining systematic success. Rather, I argue, truth bears no explanatory relation to systematic practical success. Consequently, the causal correspondence view is not in a better position to explain success than the deflationary view; theories of truth are the wrong place to look for explanations of systematic practical success.     

Meaning and mind: Wittgenstein's relevance for the ‘Does Language Shape Thought?’ debate

This paper explores the relevance of Wittgenstein's philosophical psychology for the two major contemporary approaches to the relation between language and cognition. As Pinker describes it, on the ‘Standard Social Science Model’ language is ‘an insidious shaper of thought’. According to Pinker's own widely-shared alternative view, ‘Language is the magnificent faculty that we use to get thoughts from one head to another’. I investigate Wittgenstein's powerful challenges to the hypothesis that language is a device for communicating independently constituted (or individuated) thoughts. I argue that Wittgenstein offers instead a subtle version of the thesis that language determines thought.     

Intentional concepts in cognitive neuroscience

In this article, I develop an account of the use of intentional predicates in cognitive neuroscience explanations. As pointed out by Maxwell Bennett and Peter Hacker, intentional language abounds in neuroscience theories. According to Bennett and Hacker, the subpersonal use of intentional predicates results in conceptual confusion. I argue against this overly strong conclusion by evaluating the contested language use in light of its explanatory function. By employing conceptual resources from the contemporary philosophy of science, I show that although the use of intentional predicates in mechanistic explanations sometimes leads to explanatorily inert claims, intentional predicates can also successfully feature in mechanistic explanations as tools for the functional analysis of the explanandum phenomenon. Despite the similarities between my account and Daniel Dennett's intentional-stance approach, I argue that intentional stance should not be understood as a theory of subpersonal causal explanation, and therefore cannot be used to assess the explanatory role of intentional predicates in neuroscience. Finally, I outline a general strategy for answering the question of what kind of language can be employed in mechanistic explanations.     

“I” and the brain

Many philosophers as well as many biological psychologists think that recent experiments in neuropsychology have definitively discredited any notion of freedom of the will. I argue that the arguments mounted against the concept of freedom of the will in the name of natural causal determinism are valuable but not new, and that they leave intact a concept of freedom of the will that is compatible with causal determinism. After explaining this concept, I argue that it is interestingly related to our use of the first person pronoun “I.” I discuss three examples of our use of “I” in thought and language and submit a few questions I would like neuropsychologists to answer concerning the brain processes that might underlie those uses. I suggest answering these questions would support the compatibilist notion of freedom of the will I have offered in part 1.     

Counterfactual epistemic scenarios

In two-dimensional semantics in the tradition of Davies and Humberstone, whether a singular term receives an epistemically shifted reading in the scope of a modal operator depends on whether the world considered as actual is shifted. This means that epistemically shifted readings should be available only in environments where an explicit contrast between the actual world and some counterfactual worlds cannot be made. In this paper, I argue that this is incorrect. Whether a singular term receives an epistemically shifted reading is independent of whether the world treated as actual is shifted. This, I argue, undermines the two-dimensionalist account of epistemic shift. I then turn to the question how a positive view should handle these two phenomena separately. I argue for treating singular terms with a version of counterpart theory in which the difference between epistemically shifted and other readings is determined in the context of utterance.
