Abstract
This chapter reviews the attempts of sociologists of science such as Parsons and Merton, and philosophers of science such as Kuhn, Lakatos, and Popper, to characterize the norms that guide the scientific community. In addition to positivist values such as logical coherence and empirical adequacy, scientists place a great deal of emphasis on heuristic power, conceptual simplicity, mathematical tractability, and explanatory depth. Popper’s view of science as a problem-solving activity marked by both cooperation and critical debate serves as a good reminder of the qualities that should be encouraged in public deliberations.
