Daniel Breslau's essay opens up a valuable space in seeking to align the so
ciologically impure objects explored in science studies with the practice o
f a pure sociology. I challenge Breslau's conclusion that the latter carl s
wallow the former and proceed with business as usual. Contrary to Breslau,
I argue that confronting head-on the impure objects of science studies can
indeed represent a new beginning in sociology as a discipline. I also corre
ct Breslau's misreading of my "symmetrical humanism."
