[1] Recent philosophy of mind and epistemology has seen an important and influential trend towards accounting for at least some features of experiences in content-involving terms. It is a contested point whether ascribing content to experiences can account for all the intrinsic properties of experiences, but on many theories of experiences there are close links between the ascription of content and the ways in which experiences are ascribed and typed. The issues here have both epistemological and psychological dimensions. On the one hand, a theory of experiential content has a fundamental role in explaining how knowledge of the world can be acquired through experience. On the other hand, there are important psychological questions about the phenomenology of experiences and the conditions under which content ascriptions are made.

Externalism holds, and internalism denies, that the individuation of many of an individual's mental states (e.g., thoughts about the physical world) depends necessarily on relations that individual bears to the physical and/or social environment. Many philosophers, externalists and internalists alike, believe that introspection yields knowledge of the contents of our thoughts that is direct and authoritative. It is not obvious, however, that the metaphysical claims of externalism are compatible with this epistemological thesis. Some (e.g., Burge, 1988; Falvey and Owens (F&O), 1994) have sought to dispel the worry that there is a conflict, though they admit that if such a conflict exists, it spells trouble for externalism (see, e.g., F&O, 1994, p. 108). Boghossian has argued that there is indeed a conflict between externalism and introspective knowledge of content. Surprisingly, however, he also argues that there is a conflict between internalism and introspective knowledge of content. I will defend Boghossian's claim that there is a conflict between externalism and knowledge of content, but criticize his claim that there is a conflict between internalism and knowledge of content.

It is close to current orthodoxy that perceptual experience is to be characterized, at least in part, by its representational content, roughly, by the way it represents things as being in the world around the perceiver. Call this basic idea the content view (CV).

Skeptical theses in general claim that we cannot know what we think we know. Content skepticism in particular claims that we cannot know the contents of our own occurrent thoughtsat least not in the way we think we can. I argue that an externalist account of content does engender a mild form of content skepticism but that the condition is no real cause for concern. Content externalism forces us to reevaluate some of our assumptions about introspective knowledge, but it is compatible with privileged access and the distinctive epistemic character of introspective judgments.

0. Relativistic Content In standard semantics, propositional content, whether it be the content of utterances or mental states, has a truth-value relative only to a possible world. For example, the content of my utterance of ‘Jim is sitting now’ is true just in case Jim is sitting at the time of utterance in the actual world, and the content of my belief that Alice will give a talk tomorrow is true just in case Alice will give a talk on the day following the occurrence of my belief state in the actual world. Let us call propositional content which has a truth-value relative only to a possible world ‘non-relativistic content’. Non-relativistic content can be treated as either structured or unstructured. On the unstructured-content view, non-relativistic content is a set of possible worlds and bears the truth-value true just in case the actual world is a member of that set. For example, the content of my utterance of ‘Jim is working now’ at time t is the set of worlds in which Jim is working at t, and this content is true just in case the actual world is among those worlds. On the structured-content view, non-relativistic content is a set or conglomeration of properties and/or objects, where properties are features which objects possess regardless of who considers or observes them and regardless of when they are being considered or observed. Such properties are said to be (or represent) functions from possible worlds to extensions. Relative to a possible world they determine a set of objects instantiating the property. For example, relative to the actual world the property of being human determines the set of actual humans. Not all content is non-relativistic. Let us say that propositional content is relativistic just in case it possesses a truth-value only relative to a centered world. A centered world is a possible world in which an individual and a time are marked, where the marked individual..

Davidson’s epistemology, like Kant’s, features a transcendental argument as its centerpiece. Both philosophers reject any priority, whether epistemological or conceptual, of the subjective over the objective, attempting thus to solve the problem of the external world. For Davidson, three varieties of knowledge are coordinate—knowledge of the self, of other minds, and of the external world. None has priority. Despite the epistemologically coordinate status of the mind and the world, however, the content of the mind can be shown to entail how it is out in the world. More exactly, Davidson argues, we could not possibly have the beliefs we have, with their contents, unless the world around us was pretty much the way we take it to be, at least in its general outline. We are thus offered a way to argue, to all appearances a priori, from how it is in our minds to how it is in the world. The argument is a priori at least in being free of premises or assumptions about contingent particularities concerning the world around us or our relation to it. From premises about the contents of our propositional attitudes, the argument wends its way to a conclusion about the general lines of how the world around us is structured and populated. Before presenting his own account, Davidson rejects received views of meaning and knowledge. What follows will combine themes from his critique of alternatives with his more positive account and how it deals with the skeptic.

In "Externalism, Self-Knowledge and Skepticism,"' Kevin Falvey and Joseph Owens argue that externalism with respect to mental content does not engender skepticism about knowledge of content. They go on to argue that even when externalism is freed from epistemological difficulties, the thesis cannot be used against Cartesian skepticism about knowledge of the external world. I would like to raise some questions about these claims.

"Content and Comportment argues persuasively that the answer to some long-standing questions in epistemology and metaphysics lies in taking up the neglected question of the role of our bodily activity in establishing connections between representational states—knowledge and belief in particular—and their objects in the world. It takes up these ideas from both current mainstream analytic philosophy—Frege, Dummett, Davidson, Evans—and from mainstream continental work—Heidegger and his commentators and critics—and bings them together successfully in a way that should surprise only those who persist in maintaining this barren dichotymization of the field.".
