In the past two decades, many sociologists have denied the usefulness of ge
neral theories in favor of more particularistic approaches to historical ex
planation, which makes it difficult to specify both the causal relations an
d the causal mechanisms that account for social outcomes. This article offe
rs some philosophical and theoretical justifications for the use of general
theory in historical analysis and contends that general theory guides the
selection of facts, provides a source of generalizable causal mechanisms, f
acilitates the cumulation of knowledge across substantive domains, reveals
anomalies that lead to new questions, and creates the conditions under whic
h existing theories can be supplanted by superior ones. The authors further
outline the concrete research practices that flow from their approach and
discuss several empirical studies that exemplify these five advantages.
