This article examines the connections among heuristics, the epistemological and ontological presuppositions that underlie theorizing, and substantive explanations in sociology. It develops and contrasts three heuristics: “doing as knowing” (DK), “categorizing as knowing” (CK), and “praxis as knowing” (PK). These are each composed of four dimensions: the theory of knowledge, the theory of reality, the theory of the growth of knowledge, and the theory of knowledge producers. The article then shows the importance of heuristics for empirical work by demonstrating how (...) they shape explanations in the sociological subfield of the historical sociology of knowledge. The essay draws two main conclusions: it argues that PK offers a more useful basis for developing explanations in sociology than either of the two alternatives (DK and CK) that currently shape substantive work; furthermore, it claims that the exposition of heuristic assumptions is an important task for sociology.

In a 1993 paper, I argued that empirical treatments of the epistemologyused by scientists in experimental work are too abstract in practice tocounter relativist efforts to explain the outcome of scientificcontroversies by reference to sociological forces. This was because, atthe rarefied level at which the methodology of scientists is treated byphilosophers, multiple mutually inconsistent instantiations of theprinciples described by philosophers are employed by contestingscientists. These multiple construals change within a scientificcommunity over short time frames, and these different versions ofscientific methodology (...) can determine the outcome of a controversy. Iillustrated with a comparatively detailed analysis of the methodologyused by biologists debating the existence of an entity called thebacterial mesosome between the mid-1950s and the mid-1970s. This 1993piece has drawn several critiques in the philosophical literature. Inthis present piece I respond to these critiques and argue that they failto address the core argument of the original paper, and I reflectfurther on the methodologies of philosophers of science pursuingempirical or `naturalistic' epistemology.
