The contributions to Testing Scientific Theories are unified by an in-terest in responding to criticisms directed by Glymour against existing models of confirmation—chiefly H-D and Bayesian schemas—and in assessing and correcting the "bootstrap" model of confirmation that he proposed as an alternative in Theory and Evidence (1980). As such, they provide a representative sample of objections to Glymour's model and of the wide range of new initiatives in thinking about scientific confirmation that it has influenced. The effect is a sense of engagement and focus, and of significant advance at least in articulation of the problems that require solution; as Earman observes, "it is . . . heartening to report that the various opposing camps learned from each other" (p. vi).' In what follows I am concerned to assess what has been learned both critically, about Glymour's model, and constructively about the resources of the alternatives he challenges. My thesis is that while the theories emerging in this debate do deal with a wider range of scientific practice than before, their remaining limitations raise important questions about the ambitions and criteria of adequacy that have traditionally governed philosophical inquiry in this area.

The vagaries of evidential reasoning in archaeology are notorious: the material traces that comprise the archaeological record are fragmentary and profoundly enigmatic, and the inferential gap that archaeologists must cross to constitute them as evidence of the cultural past is a peren­nial source of epistemic anxiety. And yet we know a great deal about the cultural past, including vast reaches of the past for which this material record is our only source of evidence. The contents of this record stand as evidence only under interpretation, but however much a construct it is, archaeological evidence has a striking capacity to disrupt settled assump­tions, redirecting inquiry and expanding interpretive horizons in direc­tions no one could have anticipated. It is this capacity for constraining inference and interpretation that I am concerned to understand. I outline a model of evidential reasoning based on archaeological practice that integrates insights drawn from philosophical theories of confirmation, model building and hypothesis testing. Given growing interest in the uses of material evidence in fields that had been resolutely text-based, the archaeological principles of evidential reasoning may have much wider reach than this particular social/historical discipline.

How do archaeologists make effective use of physical traces and material culture as repositories of evidence? Material Evidence is a collection of 19 essays that take a resolutely case-based approach to this question, exploring key instances of exemplary practice, instructive failures, and innovative developments in the use of archaeological data as evidence. The goal is to bring to the surface the wisdom of practice, teasing out norms of archaeological reasoning from evidence. -/- Archaeologists make compelling use of an enormously diverse range of material evidence, from garbage dumps to monuments, from finely crafted artifacts rich with cultural significance to the inadvertent transformation of landscapes over the long term. Each contributor to Material Evidence identifies a particular type of evidence with which they grapple and considers, with reference to concrete examples, how archaeologists construct evidential claims, critically assess them, and bring them to bear on pivotal questions about the cultural past. -/- Historians, cultural anthropologists, philosophers, and science studies scholars are increasingly interested in working with material "things" as objects of inquiry and as evidence – and they acknowledge on all sides just how challenging this is. One of the central messages of the book is that close analysis of archaeological best practice can yield constructive guidelines for practice that have much to offer practitioners within archaeology and well beyond.

Standpoint theory is an explicitly political as well as social epistemology. It’s distinctive features are commitment to understand the social locations that shape the epistemic capacities and resources of individuals in structural terms, and a recognition that those who are marginalized within hierarchically structured systems of social differentiation are often epistemically advantaged. In some crucial domains they know more and know better as a contingent function of their situated experience and knowledge. This “inversion thesis” counters the alignment of social with epistemic privilege.

In organizing a plenary session to mark the Quincentennial at the 1992 Annual Meeting of the Society for American Archaeology, our aim was not to provide a summary or review of archaeological research bearing on our understanding of "Columbian consequences." Rather, we sought speakers who could raise forward-looking questions about the sociopolitical entanglements and consequences of archaeology considered as, itself, part of the legacy of contact. The papers that follow, by Vine Deloria, Jalil Sued-Badillo, and Brackette F. Williams, all take up these issues and draw out implications for future practice; this introduction provides something of a rationale for the session that brought these authors together.

Solomon has made the case, in Social Empicism (2001) for socially naturalized analysis of the dynamics of scientific inquiry that takes seriously two critical insights: that scientific rationality is contingent, disunified, and socially emergent; and that scientific progress is often fostered by factors traditionally regarded as compromising sources of bias. While elements of this framework are widely shared, Solomon intends it to be more resolutely social, more thoroughly naturalizing, and more ambitiously normative than other contextualizing epistemologies currently on offer. Four focal issues are addressed in the commentaries that follow: Solomon's characterization of empirical success as a goal of science (Clough); her distinction between empirical and non-empirical decision vectors and the viability of the multivariate analysis she proposes for assessing epistemic fairness in their distribution (Clough; Richardson); the plausibility of her thesis that normatively appropriate consensus is a (rare) limiting case rather than an intrinsically desirable outcome of inquiry (Oreskes; Richardson); and her conviction that a socially naturalized analysis of science can ground norms of scientific rationality (Longino; Oreskes).

In this wide-ranging interview with three members of the Department of Philosophy at the University of Sao Paolo (Brazil) Wylie explains how she came to work on philosophical issues raised in and by archaeology, describes the contextualist challenges to ‘received view’ models of confirmation and explanation in archaeology that inform her work on the status of evidence and contextual ideals of objectivity, and discusses the role of non-cognitive values in science. She also is pressed to explain what’s feminist about feminist research and in that connection outlines her account of feminist standpoint theory and the relevance of feminist analysis to science.

Material traces of the past are notoriously inscrutable; they rarely speak with one voice, and what they say is never unmediated. They stand as evidence only given a rich scaffolding of interpretation which is, itself, always open to challenge and revision. And yet archaeological evidence has dramatically expanded what we know of the cultural past, sometimes demonstrating a striking capacity to disrupt settled assumptions. The questions we address in Evidential Reasoning are: How are these successes realized? What gives us confidence in the credibility and robustness, the trustworthiness, of the evidential claims based on archaeological data? And, what constitute best practices in building evidential claims, critically scrutinizing them and putting them to work in archaeological contexts? Rather than retreat to abstractions about how how science operates in the ideal, we approach this question by interrogating a number of close-to-the-ground case studies with the aim of teasing out the wisdom embodied in archaeological practice. The cases we consider – of fieldwork, strategies for working with old evidence, and the role of external resources – illuminate the role of various types of inferential scaffolding and bring into focus practice-grounded epistemic norms that we believe serve archaeologists better than the all-or-nothing ideals of truth and objectivity that dominate programmatic debate.

Several difficulties have been raised concerning applicability of Glymour's model to developing and "un-natural" sciences, those contexts in which he claims it should be most clearly instantiated. An analysis of testing in such a field, archaeology, indicates that while bootstrapping may be realized in general outline, practice necessarily departs from the ideal in at least three important respects 1) it is not strictly theory contained, 2) the theory-mediated inference from evidence to test hypothesis is not exclusively deductive and, 3) structural considerations do not displace or take precedence over substantive considerations. These points of divergence reflect the fact that bootstrapping in developing and exploratory sciences is as much a process of theory construction as of theory testing.

Gender research archaeology has made significant contributions, but its dissociation from the resources of feminist scholarship and feminist activism is a significantly limiting factor in its development. The essays that make up this special issue illustrate what is to be gained by making systematic use of these resources. Their distinctively feminist contributions are characterized in terms of the recommendations for “doing science as a feminist” that have taken shape in the context of the long running “feminist method debate” in the social sciences.

Archaeological facts have a perplexing character; they are often seen as less likely to “lie,” capable of bearing tangible, material witness to actual conditions of life, actions and events, but at the same time they are notoriously fragmentary and enigmatic, and disturbingly vulnerable to dispersal and attrition. As Trouillot (1995) argues for historical inquiry, the identification, selection, interpretation and narration of archaeological facts is a radically constructive process. Rather than conclude on this basis that archaeological facts and fictions are indistinguishable, I identify a number of strategies that archaeologists rely on to make discerning use of “legacy” data – archaeological data recovered and curated over for decades, even centuries, often for very different purposes than those that animate contemporary archaeological inquiry. These include source criticism, secondary retrieval, repositioning and recontextualizing these data in ways that can, sometimes radically shift the “facts” associated with them. The construction of critical genealogies of these facts – the travels and transformations of the material, interpretive and narrative facts of archaeology – is a crucial condition for the successful exploitation of these epistemic possibilities.

The groundwork has long been laid, by feminist and critical race theorists, for recognizing that a robust social epistemology must be centrally concerned with questions of epistemic injustice; it must provide an account of how inequitable social relations inflect what counts as knowledge and who is recognized as a credible knower. The cluster of papers we present here came together serendipitously and represent a striking convergence of interest in exactly these issues. In their different ways, each contributor is concerned both to understand how dominant epistemic norms perpetuate ignorance and injustice and to articulate effective strategies for redressing these inequities.
