This paper distinguishes two projects in Davidson's theory of meaning, an initial project of providing a compositional meaning theory for a natural language for which a Tarski-style truth theory is pressed into service and an extended project that aims to illuminate the basis of meaning in its relation to the neutrally described behavioral evidence in terms of which an interpretive truth theory for a language can ultimately be confirmed, and then argues that having distinguished the two projects we can see that the goal that the radical interpreter sets himself cannot be achieved given the limits on his data.

Kirk Ludwig develops a novel reductive account of plural discourse about collective action and shared intention. Part I develops the event analysis of action sentences, provides an account of the content of individual intentions, and on that basis an analysis of individual intentional action. Part II shows how to extend the account to collective action, intentional and unintentional, and shared intention, expressed in sentences with plural subjects. On the account developed, collective action is a matter of there being multiple agents of an event and it requires no group agents per se. Shared intention is a matter of agents in a group each intending that they bring about some end in accordance with a shared plan. Thus their participatory intentions differ from individual intentions not in their mode but in their content. Joint intentional action then is a matter of a group of individuals successfully executing a shared intention.

I begin by distinguishing between what I will call a pure Fregean theory of reference and a theory of direct reference. A pure Fregean theory of reference holds that all reference to objects is determined by a sense or content. The kind of theory I have in mind is obviously inspired by Frege, but I will not be concerned with whether it is the theory that Frege himself held.1 A theory of direct reference, as I will understand it, denies that all reference to objects is determined by sense or content. We will also distinguish between a theory of reference for thought, and for language. This gives us a fourfold classification of theories. What is puzzling about direct reference theories is not that the semantics of an expression in a public language should assign as its semantic value just a referent, but how such facts could be understood to reflect an underlying feature of thought. There are two interconnected aspects to this..

This paper is concerned with a recent, clever, and novel argument for the need for genuine collectives in our ontology of agents to accommodate the kinds of normative judgments we make about them. The argument appears in a new paper by David Copp, "On the Agency of Certain Collective Entities: An Argument from 'Normative Autonomy'" (Midwest Studies in Philosophy: Shared Intentions and Collective Responsibility, XXX, 2006, pp. 194-221; henceforth ‘ACE’), and is developed in Copp’s paper for this special journal issue, “The Collective Moral Autonomy Thesis” (henceforth ‘CAT’). The argument goes as follows. (1) We correctly assign blame (or obligations) to collectives in circumstances in which it would be a mistake to assign any (relevantly related) blame (or obligations) to their members. (2) If (1), then collectives are genuine agents over and above their members. (3) Therefore, collectives are genuine agents over and above their members. Following Copp, I call (1) the Collective Moral Autonomy Thesis (CMA). Copp argues for CMA primarily by appeal to cases, but also offers two general arguments for it. In the cases that Copp describes, we are to judge that a collective act is blameworthy, though each member of the group that acts is blameless because he is merely following procedures appropriate for his participation, or because there are excusing factors, or because of overriding personal duties. I argue that the case for CMA has not been made. In particular, I argue that, in each case in which we feel inclined to hold a group responsible for something but not its members, it is because 1. we have accepted a false dilemma, that when no one agent is fully responsible for the action of a group of which he is a member, the only entity that could be responsible is the group as such, or 2. we have directed our attention to the wrong individual or individuals, or 3. we have become confused about the commitments of the individuals, or 4. we have mistaken ameliorating for excusing factors, or 5. we have mistaken moral blameworthiness and all-in rational blameworthiness, or 6. a combination of these things.

Ludwig deals with the relations between language, thought, and rationality, and, especially, the role and status of assumptions about rationality in interpreting another’s speech and assigning contents to her psychological attitudes—her beliefs, desires, intentions, and so on. The chapter is organized around three questions: What is the relation between rationality and thought? What is the relation between rationality and language? What is the relation between thought and language? Ludwig argues that some large degree of rationality is required for thought and consequently that same degree of rationality at least is required for language since language requires thought. Thought, however, does not require language. In answering questions and, Ludwig gives particular attention to Davidson’s arguments for the Principle of Charity, according to which it is constitutive of speakers that they are largely rational and largely right about the world, and to Davidson’s arguments for the thesis that without the power of speech we lack the power of thought.

Our aim in the present paper is to investigate, from the standpoint of truth-theoretic semantics, English tense, temporal designators and quantifiers, and other expressions we use to relate ourselves and other things to the temporal order. Truth-theoretic semantics provides a particularly illuminating standpoint from which to discuss issues about the semantics of tense, and their relation to thoughts at, and about, times. Tense, and temporal modifiers, contribute systematically to conditions under which sentences we utter are true or false. A Tarski-style truth-theoretic semantics, by requiring explicitly represented truth conditions, helps to sharpen questions about the function of tense, and to deepen our insight into the contribution the tenses and temporal modifiers make to what we say by using them.

This chapter reviews interpretations of Davidson's project in the theory of meaning and argues against a variety of views according to which Davidson intended to reduce meaning to some variety of truth conditions or replace the project of giving a theory of meaning with a theory of truth, and in support of interpreting him as offering an indirect way of achieving the goals of the traditional project by appeal to knowledge of facts about a semantic theory of truth for the language, including that it was confirmable from the standpoint of the radical interpreter.

How are we able to perceive the world veridically? If we ask this question as a part of the scientific investigation of perception, then we are not asking for a transcendental guarantee that our perceptions are by and large veridical; we presuppose that they are. Unless we assumed that we perceived the world for the most part veridically, we would not be in a position to investigate our perceptual abilities empirically. We are interested, then, not in how it is possible in general for us to perceive the world veridically, but instead in what the relation is between our environment and its properties, of which we have knowledge, on the one hand, and our perceptual mechanisms, on the other, that results in very many, even most of our perceptions being veridical in everyday life.

Social externalism is the view that the contents of a person's propositional attitudes are logically determined at least in part by her linguistic community's standards for the use of her words. If social externalism is correct, its importance can hardly be overemphasized. The traditional Cartesian view of psychological states as essentially first personal and non-relational in character, which has shaped much theorizing about the nature of psychological explanation, would be shown to be deeply flawed. I argue in this paper that social externalism faces insuperable difficulties. The first difficulty is that if syntax and semantics are independent, then social externalism is committed to the absurd consequence that many people have beliefs with formally inconsistent contents. I argue none of the possible responses to this objection are plausible. The second difficulty is that if syntax and semantics are independent, then social externalists are committed to a contradiction. After raising and defending these objections, I identify what I think is the underlying flaw in the social externalist position, a failure to pay attention to the structure of communication intentions, and briefly indicate how to neutralize the linguistic evidence social externalists advance in favor of their view.

Corporations have often been taken to be the paradigm of an organization whose agency is autonomous from that of the successive waves of people who occupy the pattern of roles that define its structure, which licenses saying that the corporation has attitudes, interests, goals, and beliefs which are not those of the role occupants. In this essay, I sketch a deflationary account of agency-discourse about corporations. I identify institutional roles with a special type of status function, a status role, in which the collectively accepted function is expressed in part through its occupier’s intentional expression of her agency in that role. I identify institutions as systems of status roles and show how this is compatible with seeing the agency of institutions generally, even over time periods in which there is complete change in role occupiers, as a matter of the contributions only of individual agents. I explain how the reduction of the institution to its members is compatible with its potentially having had a completely different membership. I show in the case of the corporation in particular that, once we see its origins and function, the surface features of legal discourse about corporate agency are misleading and are compatible with a deflationary account of corporate agency. I show in connection with this that the corporation is to be identified with its shareholders, and that where a corporation separates ownership and control, its managers and employees are proxy agents of the shareholders doing business under the corporate form. Finally, I canvass the legitimate ways of construing ordinary talk about corporate intention, belief, and so on, in light of this, none of which support the attribution of genuine agency or intentionality to any group per se associated with the corporation.

Radical skepticism about the external world is founded on two assumptions: one is that the mind and the external world are logically independent; the other is that all our evidence for the nature of that world consists of facts about our minds. In this paper, I explore the option of denying the epistemic, rather than the logical assumption. I argue that one can do so only by embracing externalism about justification, or, after all, by rejecting the logical independence assumption. Since (I argue) externalism is not a solution to the problem of skepticism, this means that skepticism is false only if the mind and the world are not logically independent.

This paper evaluates Putnam’s argument in the first chapter of Reason, Truth and History, for the claim that we can know that we are not brains in a vat (of a certain sort). A widespread response to Putnam’s argument has been that if it were successful not only the world but the meanings of our words (and consequently our thoughts) would be beyond the pale of knowledge, because a causal theory of reference is not compatible with our having knowledge of the meanings of our words. I argue that this is not so. I argue also, however, that given how Putnam argues (here) for the causal theory of reference, he cannot after all escape this consequence.

An important objection to sententialist theories of attitude reports is that they cannot accommodate the principle that one cannot know that someone believes that p without knowing what it is that he believes. This paper argues that a parallel problem arises for propositionalist accounts that has gone largely unnoticed, and that, furthermore, the usual resources for the propositionalist do not afford an adequate solution. While non-standard solutions are available for the propositionalist, it turns out that there are parallel solutions that are available for the sententialist. Since the difficulties raised seem to show that the mechanism by which sentential complements serve to inform us about attitudes and about sentence meaning does not depend on their referring to propositions, this casts doubt on whether talk of propositions should retain a significant theoretical role in the enterprise of understanding thought, language and communication.

Let us call a thought or belief whose content would be expressed by a sentence of subject-predicate form (by the thinker or someone attributing the thought to the thinker) an ‘ascription’. Thus, the thought that Madonna is middle-aged is an ascription of the property of being middle-aged to Madonna. To call a thought of this form an ascription is to emphasize the predicate in the sentence that gives its content. Let us call an ‘x-ascription’ an ascription whose subject is x, that is, an ascription such that the subject of the sentence which would express its content is x. Let us call a ‘self-ascription’ an ascription whose subject is identical with the ascriber. Let us call a ‘reflexive ascription’ a selfascription such that either (i) in the sentence the ascriber would use to attribute correctly the ascription to himself he would use the first person pronoun to refer to himself both as the ascriber and as the subject of the ascription, as in a sentence of the form, I believe that I ö

What is the ontology of collective action? I have in mind three connected questions. 1. Do the truth conditions of action sentences about groups require there to be group agents over and above individual agents? 2. Is there a difference, in this connection, between action sentences about informal groups that use plural noun phrases, such as ‘We pushed the car’ and ‘The women left the party early’, and action sentences about formal or institutional groups that use singular noun phrases, such as ‘The United States declared war on Japan on December 8th, 1941’ and ‘The Supreme Court ruled that segregation is unconstitutional in 1954 in Brown vs. Board of Education’? 3. Under what conditions does it make sense to speak of a group doing something together, and what, if anything, is a collective action? In this paper, I argue that a) understanding action sentences about groups does not commit us to the existence of group agents per se, but only to the existence of individual agents; b) there is no difference in this regard between sentences which attribute actions to informal groups on the one hand and institutional groups on the other; c) collective action can be both intentional and unintentional; d) any random group of agents each of whom does something is also a group which does something together; e) while there is a sense in which groups per se perform no primitive collective actions, and therefore no actions at all, f) there is a sensible extension of talk of actions to groups, though it should be treated strictly speaking, like talk of group agents, as a façon de parler, for g) the only agents per se are individuals and the only actions are theirs. -/-

Assertoric sentences are sentences which admit of truth or falsity. Non-assertoric sentences, imperatives and interrogatives, have long been a source of difficulty for the view that a theory of truth for a natural language can serve as the core of a theory of meaning. The trouble for truth-theoretic semantics posed by non-assertoric sentences is that, prima facie, it does not make sense to say that imperatives, such as 'Cut your hair', or interrogatives such as 'What time is it?', are truth or false. Thus, the vehicle for giving the meaning of a sentence by using an interpretive truth theory, the T-sentence, is apparently unavailable for non-assertoric sentences. This paper shows how to incorporate non-assertoric sentences into a theory of meaning that gives central place to an interpretive truth theory for the language, without, however, reducing the non-assertorics to assertorics, or treating their utterances as semantically equivalent to one or more utterances of assertoric sentences. Four proposals for how to incorporate non-assertoric sentences into a broadly truth-theoretic semantics are reviewed. The proposals fall into two classes, those that attempt to explain the meaning of non-assertoric sentences solely by appeal to truth conditions, and those that attempt to explain the meaning of non-assertroic sentences by appeal to compliance conditions, which can be treated as one variety of fulfillment conditions for sentences of which truth conditions are another variety. The paper argues that none of the extant approaches is successful, but develops a version of the generalized fulfillment approach which avoids the difficulties of previous approaches and still exhibits a truth theory as the central component of a compositional meaning theory for all sentences of natural language.

Suppose that a physical duplicate of me, right down to the arrangements of subatomic particles, comes into existence at the time at which I finish this sentence. Suppose that it comes into existence by chance, or at least by a causal process entirely unconnected with me. It might be so situated that it, too, is seated in front of a computer, and finishes this paragraph and paper, or a corresponding one, just as I do. (i) Would it have the same thoughts I do? (ii) Would it speak my language? (iii) Would my duplicate have any thoughts or (iv) speak any language at all? To fix the interpretation of these questions, I will take ‘thought’ to cover any mental state which has a representational content, where ‘representational content’ is intended to be neutral with respect to psychological mode. By 'psychological mode' I mean what distinguishes kinds of thoughts, such as belief, visual perceptual experience, desire, etc. Representational content, or thought content, as I will also say, determines the conditions under which a thought is true or false, veridical or non-veridical, or, more broadly, is satisfied or fails to be satisfied, independently of relativization to circumstances, possible worlds, or the like. Beliefs, desires, hopes, intentions, and perceptual experiences will all count as thoughts on this usage. The question whether one person has the same (type of) thought as another is the question whether both have a mental state with the same representational content in the same psychological mode. I will not count epistemic verbs, however, as picking out or expressing a (pure) psychological mode. Thus, although knowing that the time is ripe, seeing that there is a goldfinch in the garden, and remembering that my wife’s birthday is next Tuesday are all thoughts, they do not pick out the thoughts by using a verb that expresses a psychological mode. Therefore knowing, seeing or remembering the same things is not a requirement on having the same thoughts..

Martine Nida-Rümelin has argued recently for subject-body dualism on the basis of reflections on the possibility of survival in fission cases from the literature on personal identity. The argument focuses on the claim that there is a factual difference between the claims that one or the other of two equally good continuers of a person in a fission case is identical with her. I consider three interpretations of the notion of a factual difference that the argument employs, and I argue that on each of them the argument either begs the question or is unsound.

Donald Davidson has argued that attention to the necessarily public character of language shows that we cannot be massively mistaken about the world around us, and that consequently skeptical doubts about empirical knowledge are misplaced. The arguments Davidson advances rely on taking as the fundamental methodological standpoint for investigating meaning and related concepts the standpoint of the interpreter of another speaker, on the grounds that it is from the interpreter’s standpoint that we discover what constraints are placed on meaning by the public character of language. In this paper, I argue that although Davidson’s arguments reveal important conceptual connections between meaning and belief on the one hand, and truth and interpretation on the other, they do not show that it is impossible that we are massively mistaken about the external world.

This paper advances a general argument, inspired by some remarks of Davidson, to show that appeal to meanings as entities in the theory of meaning is neither necessary nor sufficient for carrying out the tasks of the theory of meaning. The crucial point is that appeal to meaning as entities fails to provide us with an understanding of any expression of a language except insofar as we pick it out with an expression we understand which we tacitly recognize to be a translation of the term whose meaning we want to illuminate by the appeal to assigning to it a meaning. The meaning drops out as irrelevant: the work is done, and can only be done, by matching terms already understood with terms they translate.

The paper rejects the claim that phenomena such as change and inattentional blindness show that perceptual representations are inaccurate or that a radical overhaul of our traditional picture of perception is required. The paper rejects in particular the sensorimotor theory of perception, which denies that there are any perceptual representations. It further argues that the degree of resolution of perceptual experience relevant to assessing its accuracy is determined by our use of it in standard conditions, and that the integration of behavior with perceptual representation shows that it is by and large as accurate as its degree of resolution requires.
