The purpose of this forum is to contribute to the ongoing conversation about archaeology as it might be of service beyond its traditional roles. The observation that archaeology plays a role in society beyond its contribution to knowledge is not new; there are increasing numbers of archaeologists determined to use their expertise to make the world a better place. What I hope in this forum is that I and my colleagues make a fruitful contribution to the ongoing dialogue about potential and actual benefits of archaeology related to doing justice, making peace, building community, and restoring ecological balance. In a recent issue of The SAA Archaeological Record, ethnobotanist and archaeologist Paul Minnis initiated a dialogue about "The Skep tic's Question" because he is concerned that archaeologists don't know how to make the case for what we do (Minnis et al. 2006). The skeptic, in this case, is the person who asks, essentially, why spend public money?that is, tax dollars?on archaeology instead of spending the money for more obviously important things such as schools, medical research, or reduc ing poverty. In addition to Minnis, six other archaeologists?five prehistorians and one his torical archaeologist (me)?offered short versions of our answers to why archaeology is relevant today. Our responses ranged from ecological conservation and the diversification of crops, to the encouragement of long-term perspectives on public decision making, to tourism, to promoting heritage and identity, to battling racism. Our responses to the "skeptic's question" assume that the archaeology that will be useful will be competent, scholarly archaeology. The need to ask the question and to "make the case" relates to increasing anxiety about public relevance throughout the sciences and humanities. Generations of archaeologists have felt strongly the need for their work to be useful, not only to justify continued funding, but also to act as responsible scholars. Archaeologists have disagreed, however, about what counts as usefulness, often ridiculing work that falls outside of one's own "camp." Archaeologists too often fight about a basic division presumed to split the discipline. One kind of archaeology is a science, which provides credible and hopefully useful knowledge. One kind of archaeology is a humanity, which provides meaning and perspective on life within the human condition over time and across space. Sometimes we integrate those two identities well, and sometimes we do not. The kinds of benefits we hope to provide depend on how we see the purpose and strengths of our field. It may be that one of the most beneficial things we could do?for ourselves, for the social sciences, for intellectual life, for policy makers, for a broad range of interested publics ?is to do a better job of integrating the values of the humanities and the sciences and making the case, by example, of how to do that. As archaeologists, we know that there are many scholars who could use archaeology to do a better job in their own research and that there are many people who could use archaeology to make their lives richer. One example contribut ing to research impacts outside of archeology is useful data for ecologists and environmental researchers who need a longer-term view than is often available on the ecological effects of industry and globalization. And, for enriching lives, for example, we want teachers and students to learn archaeology, not only so that they'll support it, and not only so that they see the world is diverse in peoples and cultures, but also to learn about how one might make sense of a process deeply imbued with ambiguity, complexity, and uncertainty and to gain the insight that those characteristics apply to life in general no less than to the messy business of archaeology. In addition, we want communities and archaeologists to engage with each other and to use the process and results of
