ABSTRACT
This volume, and the workshop on which it draws, reflects the fact that evolutionary economics, or at least bodies of thought and writing that are associated with that term, have become increasingly fashionable. In this chapter, I will discuss the kind of evolutionary theory Sidney Winter and I, and kindred souls both in economics and in other fields of social science, have been trying to develop. However, our particular orientation toward evolutionary theory is only one of several that are impinging on economic analysis. While the different strands have certain things in common, there also are some major differences. It is useful, therefore, to begin by laying out some of the differences as well as the similarities.
