History matters because time and place matter and because of path-depe
ndence. Hence only idiographic and not nomothetic statements are possi
ble according to some historical sociologists. Others accuse the forme
r of having abandoned science. It is not sufficiently appreciated that
in understanding the role of both history and necessity, evolutionary
theory has solved this problem. Moreover, methods available for infer
ring what is uniquely related to what, having come via the same path,
and for testing hypotheses controlling for the possibly confounding ef
fects of common histories should be of interest to sociologists on bot
h sides of the history versus science divide.
