Nelson Goodman’s work is universally regarded as pioneering and fundamental, and his attempts to clarify the nature of induction, symbol systems, art, theorizing and understanding have received and continue to receive great attention. Central to that work is a view Goodman describes as “radically relativist.” Goodman’s unusual brand of relativism, however, while basic to the entire Goodman corpus, has yet to be carefully delineated and studied. I hope in this paper to begin such a study. I will first briefly review (...) the development of Goodmanian relativism through his earlier books and articles. Then I will develop a more detailed and elaborate account of the relativist position Goodman develops in his most recent book, Ways of Worldmaking. Because Goodman’s relativism is significantly different from more traditional accounts of relativism, I will attempt to shed light on Goodmanian relativism by contrasting it with those more traditional accounts. Finally, I will argue that there is a crucial ambiguity in Goodman’s portrayal and defense of relativism, having to do with the role of “criteria of rightness” in Goodman’s system, and that this ambiguity licenses two quite distinct versions of Goodmanian relativism. I will argue that the weak version of relativism is defensible, and important, but that the strong, or “radical,” relativist position suffers from a fatal flaw. My hope is that the paper will serve to clarify not only Goodman’s position, but epistemological relativism more generally. (shrink)
