Abstract
The critique of Robert K. Merton in terms of the criteria relevant for the history of methodology is misdirected. Merton has never been a methodologist, and his influential notion of middle-range theories has been merely a polemical position taken both against pure abstract, conceptual constructs, and narrow fact-finding. It helped sociology to sustain fruitful directions of research, free from abuses of "grand theory" as well as pure empiricism. Merton's true and many "arrivals" (read: contributions to sociology) have been substantive and not meta-theoretical. Because of them he is a classic of twentieth-century sociology. Key Words: middle-range theory • history of methodology • sociological theory.
