'Since the publication of The Philosophy and Methodology of Economics, edited by Bruce Caldwell, the range of topics and of approaches has greatly expanded, and not only in predictable directions. We now have extensive debates about the scope of the subject (and whether that is itself a set of appearances defined by our interpretations), the processes of theory invention, the social, psychological and economic influences on these processes, including the assumptions and boundaries that are appropriate and the kinds of causal explanations that are acceptable, the importance of persuasion and the role of narrative. Exploration of these conceptual issues is now increasingly complemented by investigations of the variety and evolution of economists' practice; these are not only intrinsically welcome, but may engage the interest of those who shun "methodology". This collection offers a substantial and accessible guide to what has been happening, and should encourage readers to watch out for, and even participate in, further developments.'
