Perception enables us to think demonstrative thoughts about the world around us, but what must perception be like in order to play this role? Does perception enable demonstrative thought only if it is conscious? This paper examines three accounts of the role of consciousness in demonstrative thought, which agree that consciousness is essential for demonstrative thought, but disagree about why it is. First, I consider and reject the accounts proposed by Gareth Evans in The Varieties of Reference and by John (...) Campbell in Reference and Consciousness before offering an alternative proposal of my own. My proposal is that consciousness plays an essential epistemic role in explaining the capacity for demonstrative thought about an object by enabling the subject to form immediately justified beliefs about the object.

According to an attractive account of belief, our beliefs have centered content. According to an attractive account of communication, we utter sentences to express our beliefs and share them with each other. However, the two accounts are in conflict. In this paper I explore the consequences of holding on to the claim that beliefs have centered content. If we do in fact express the centered content of our beliefs, the content of the belief the hearer acquires cannot in general be (...) identical to the content the speaker expresses. I sketch an alternative account of communication, the Recentering model, that accepts this consequence and explains how expressed and acquired content are related. (shrink)

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

This paper concerns two points of intersection between de se attitudes and the study of natural language: attitude ascription and communication. I first survey some recent work on the semantics of de se attitude ascriptions, with particular attention to ascriptions that are true only if the subject of the ascription has the appropriate de se attitude. I then examine – and attempt to solve – some problems concerning the role of de se attitudes in linguistic communication.

Traditional procedures for rational updating fail when it comes to self-locating opinions, such as your credences about where you are and what time it is. This paper develops an updating procedure for rational agents with self-locating beliefs. In short, I argue that rational updating can be factored into two steps. The first step uses information you recall from your previous self to form a hypothetical credence distribution, and the second step changes this hypothetical distribution to reflect information you have genuinely (...) learned as time has passed. While the second step resembles traditional procedures of updating by conditionalization, the first is best understood by analogy to traditional models of how agents transmit self-locating opinions through ordinary interpersonal communication.

I hear the patter of little feet around the house, I expect Bruce. What I expect is a cat, a particular cat. If I heard such a patter in another house, I might expect a cat but no particular cat. What I expect then seems to be a Meinongian incomplete cat. I expect winter, expect stormy weather, expect to shovel snow, expect fatigue---a season, a phenomenon, an activity, a state. I expect that someday mankind will inhabit at least five planets. (...) This time what I expect is a state of affairs. If we let surface grammar be our guide, the objects of expectation seem quite a miscellany. The same goes for belief, since expectation is one kind of belief. The same goes for desire: I could want Bruce, want a cat but no particular cat, want winter, want stormy weather, want to shovel snow, want fatigue, or want that someday mankind will inhabit at least five planets. The same goes for other attitudes to the extent that they consist partly of beliefs or desires or lacks thereof. But the seeming diversity of objects might be an illusion. Perhaps the objects of attitudes are uniform in category, and it is our ways of speaking elliptically about these uniform objects that are diverse. That indeed is our consensus. We mostly think that the attitudes uniformly have propositions as their objects. That is why we speak habitually of "propositional attitudes.". (shrink)

Perry argues that certain sorts of indexicals are 'essential', in the sense that they cannot be eliminated in favor of descriptions. This paper also introduces the influential idea that certain sorts of indexicals play a special role in thought, and have a special connection to action.

In recent years, several philosophers have defended the idea of phenomenal intentionality : the intrinsic directedness of certain conscious mental events which is inseparable from these events’ phenomenal character. On this conception, phenomenology is usually conceived as narrow, that is, as supervening on the internal states of subjects, and hence phenomenal intentionality is a form of narrow intentionality. However, defenders of this idea usually maintain that there is another kind of, externalistic intentionality, which depends on factors external to the subject. (...) We may ask whether this concession to content externalism is obligatory. In this paper, I shall argue that it isn’t. I shall suggest that if one is convinced that narrow phenomenal intentionality is legitimate, there is nothing stopping one from claiming that all intentionality is narrow. (shrink)

I suggest a way of extending Stalnaker’s account of assertion to allow for centered content. In formulating his account, Stalnaker takes the content of assertion to be uncentered propositions: entities that are evaluated for truth at a possible world. I argue that the content of assertion is sometimes centered: the content is evaluated for truth at something within a possible world. I consider Andy Egan’s proposal for extending Stalnaker’s account to allow for assertions with centered content. I argue that Egan’s (...) account does not succeed. Instead, I propose an account on which the contents of assertion are identified with sets of multi-centered worlds. I argue that such a view not only provides a plausible account of how assertions can have centered content, but also preserves Stalnaker’s original insight that successful assertion involves the reduction of shared possibilities.

There is now a considerable literature that goes under the heading of “phenomenal intentionality.” But it features a number of distinct issues. What they have in common is the claim that intentionality bears a closer relation to phenomenology than had previously been recognized. There is a basic thesis, which is controversial, and there are further arguments attempting to draw more exciting morals from the basic thesis. My purpose in this paper is to survey these issues, see what may be at (...) stake, and adjudicate. (shrink)

The concepts of meaning and mental content resist naturalistic analysis. This is because they are normative: they depend on ideas of how things ought to be.

Inspired by Castañeda, Perry and Lewis argued that, among singular thoughts in general, thoughts about oneself ‘as oneself’ – first-personal thoughts, which Lewis aptly called de se – call for special treatment: we need to abandon one of two traditional assumptions on the contents needed to provide rationalizing explanations, their shareability or their absoluteness. Their arguments have been very influential; one might take them as establishing a new ‘effect’ – new philosophical evidence in need of being accounted for. This is (...) questioned by the skeptical arguments in recent work by Cappelen & Dever and Magidor, along lines that a few discrepant voices had already announced earlier. Skeptics content that the evidence does not really call for revising traditional theories of content. I will discuss their challenges – first and foremost, concerning action explanations – aiming to make the case that the ‘De Se effect’ is no illusion: de se attitudes require us to revise one of the two tenets of traditional views.

Human self-consciousness operates at different levels of complexity and at least comprises five different levels of representational processes. These five levels are nonconceptual representation, conceptual representation, sentential representation, meta-representation, and iterative meta-representation. These different levels of representation can be operationalized by taking a first-person-perspective that is involved in representational processes on different levels of complexity. We refer to experiments that operationalize a first-person-perspective on the level of conceptual and meta-representational self-consciousness. Interestingly, these experiments show converging evidence for a recruitment of (...) medial cortical and parietal regions during taking a first-person-perspective, even when operating on different degrees of complexity. These data lend support for the speculative hypothesis, that there exist a neural signature for human self-consciousness that is recruited independent from the degree of representational complexity to be performed.
