With this issue Episteme makes its debut with Cambridge University Press, after eight successful years of publication at Edinburgh University Press. The journal’s new subtitle reflects a significant expansion in scope and mission. Our previous subtitle, ‘A Journal of Social Epistemology’, reflected our earlier focus on the nascent field of social epistemology. The new subtitle, ‘A Journal of Individual and Social Epistemology’, reflects a new self-definition as a full-spectrum journal of epistemology, including the complete remit of analytic epistemology.

One possible aim of epistemology is to advise cognizers on the proper choice of beliefs or other doxastic attitudes. This aim has often been part of scientific methodology: to tell scientists when they should accept a given hypothesis, or give it a certain degree of credence. This regulative function is naturally linked to the notion of epistemic justification. It may well be suggested that a cognizer is justified in believing something just in case the rules of proper epistemic procedure prescribe that belief. Principles that make such doxastic prescriptions might thereby "double" as principles of justification. In the first part of this paper I contrast the regulative conception of justification with another, equally tenable, conception. Then, after noting a fundamental worry about the applicability of the regulative conception, I proceed to lay it out in more detail. The regulative justificational status of a doxastic attitude for person S at time t depends upon (a) the right set of doxastic instructions and (b) the states S is in at (or just before) t.

The ordinary understanding and ascription of mental states is a multiply complex subject. Widely discussed approaches to the subject, such as functionalism and the theory-theory (TT), have many variations and interpretations. No surprise, then, that there are misunderstandings and disagreements, which place many items on the agenda. Unfortunately, the multiplicity of issues raised by the commentators and the limitations of space make it impossible to give a full reply to everyone. My response is divided into five topics: (1) Which version(s) of functionalism are candidates for an account of folk psychology, and is any such version satisfactory? (2) Where does TT stand in light of the two target articles and commentaries? (3) Does a phenomenological story provide a promising account of mental states, and is there special first-person authority about them? (4) What are suitable methodological assumptions for our subject matter? (5) How well does the simulation theory fare as an account of third-person mentalistic ascription?

What is the mission of epistemology, and what is its proper methodology? Such meta-epistemological questions have been prominent in recent years, especially with the emergence of various brands of "naturalistic" epistemology. In this paper, I shall reformulate and expand upon my own meta-epistemological conception (most fully articulated in Goldman, 1986), retaining many of its former ingredients while reconfiguring others. The discussion is by no means confined, though, to the meta-epistemological level. New substantive proposals will also be advanced and defended.

Epistemology has historically focused on individual inquirers conducting their intellectual affairs in total isolation from one another. Methodological solipsism aside, however, it is incontestable that people’s opinions are massively influenced by their community and culture, by the written and spoken words of others, both past and present. This has led recent epistemologists to pay greater attention to the social dimensions of knowledge, especially to the role of testimony as a source of justification. The aim of Knowledge in a Social World is to articulate a more systematic and wide-ranging conception of social epistemology, a conception that forges links with both empirical and policy-oriented disciplines that study the place of knowledge in society. On the one hand, it steers social epistemology along paths continuous with mainstream epistemology and philosophy of science; on the other, it carries epistemology into greater contact than is customary with political philosophy, legal philosophy, and such new or peripheral fields as Internet epistemology and philosophy of education. Although it never abandons the theoretical mission of epistemology, it also makes concerted forays into what may be called “applied epistemology”.

A new class of visuomotor neuron has been recently discovered in the monkey’s premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental evidence suggests that a similar matching system also exists in humans. What might be the functional role of this matching system? One possible function is to enable an organism to detect certain mental states of observed conspecifics. This function might be part of, or a precursor to, a more general mind-reading ability. Two different accounts of mind-reading have been suggested. According to “theory theory‘, mental states are represented as inferred posits of a naive theory. According to “simulation theory‘, other people’s mental states are represented by adopting their perspective: by tracking or matching their states with resonant states of one’s own. The activity of mirror neurons, and the fact that observers undergo motor facilitation in the same muscular groups as those utilized by target agents, are findings that accord well with simulation theory but would not be predicted by theory theory.

This article examines a thesis of interest to social epistemology and some articulations of First Amendment legal theory: that a free market in speech is an optimal institution for promoting true belief. Under our interpretation, the market-for-speech thesis claims that more total truth possession will be achieved if speech is regulatedonlyby free market mechanisms; that is, both government regulation and private sector nonmarket regulation are held to have information-fostering properties that are inferior to the free market. After discussing possible counterexamples to the thesis, the article explores the actual implications of economic theory for the emergence of truth in a free market for speech. When confusions are removed about what is maximized by perfectly competitive markets, and when adequate attention is paid to market imperfections, the failure of the market-for-speech thesis becomes clear. The article closes by comparing the properties of a free market in speech with an adversarial system of discourse.

This paper offers a sizeable menu of approaches to what it means to be an expert. Is it a matter of reputation within a community, or a matter of what one knows independently of reputation? An initial proposal characterizes expertise in dispositional terms—an ability to help other people get answers to difficult questions or execute difficult tasks. What cognitive states, however, ground these abilities? Do the grounds consist in “veritistic” states or in terms of evidence or justifiedness? To what extent is expertise a matter of superior knowledge or other factors? Some authors seek to debunk the notion of expertise entirely. The present approach resists this stance, but doesn’t dispute the variability and fluidness of the concept. Even more challenging is the problem of how laypersons can determine who is the superior expert, especially when experts disagree.

Epistemology has had a strongly individualist orientation, at least since Descartes. Knowledge, for Descartes, starts with the fact of one’s own thinking and with oneself as subject of that thinking. Whatever else can be known, it must be known by inference from one’s own mental contents. Achieving such knowledge is an individual, rather than a collective, enterprise. Descartes’s successors largely followed this lead, so the history of epistemology, down to our own time, has been a predominantly individualist affair.

Knowledge in a Social World offers a philosophy for the information age. Alvin Goldman explores new frontiers by creating a thoroughgoing social epistemology, moving beyond the traditional focus on solitary knowers. Against the tides of postmodernism and social constructionism Goldman defends the integrity of truth and shows how to promote it by well-designed forms of social interaction. From science to education, from law to democracy, he shows why and how public institutions should seek knowledge-enhancing practices. The result is a bold, timely, and systematic treatment of the philosophical foundations of an information society

Consciousness researchers standardly rely on their subjects’ verbal reports to ascertain which conscious states they are in. What justifies this reliance on verbal reports? Does it comport with the third-person approach characteristic of science, or does it ultimately appeal to first-person knowledge of consciousness? If first-person knowledge is required, does this pass scientific muster? Several attempts to rationalize the reliance on verbal reports are considered, beginning with attempts to define consciousness via the higher-order thought approach and functionalism. These approaches are either problematic in their own right, or ultimately based on a first-person access to consciousness. A third approach assumes that scientists can trust verbal reports because subjects reliably monitor or ‘introspect’ their conscious states. This raises the question of whether the reliability of introspection can be validated by independent criteria. Merikle's attempts to validate this reliability are shown to involve some unavoidable circularity. It is conjectured that scientists’ reliance on their subjects’ verbal reports tacitly appeals to their own introspective reliability, which is not independently validatable. Some epistemologists might conclude that this renders scientists’ conclusions about conscious states unjustified, but I argue that this does not contravene the constraints of a proper epistemology.
