Thomas Kuhn, Revolutions, Paradigms, and Progress
The Problem of Progress
The question I’m addressing today, is on Thomas Kuhn’s Structure of Scientific Revolutions. It was posed to me recently, in this form: “Is Kuhn right that we cannot speak of progress across scientific paradigms?” This paper will briefly summarize Kuhn’s own definition of progress both within and across paradigms, explore the implications of these definitions, and assess the conclusion Kuhn comes to at the end of Chapter XIII of The Structure of Scientific Revolutions. The overall argument of this paper is that the initial question is misleading when compared to what Kuhn actually argues, but that Kuhn is still mistaken in his rejection of the notion of progress because elsewhere he admits himself that incommensurability does not deny the possibility of measurement, and because the analogy to evolution is fundamentally flawed. The paper will conclude with a few summary remarks about progress, both as it relates to science, and as a general concept.
