While symmetry and impartiality have become ruling principles in S&TS,
defining its core ideal of a 'value-free relativism', their philosoph
ical anchorage has attracted much less discussion than the issue or:ho
w far their jurisdiction can be extended or generalized. This paper se
eks to argue that symmetry and agnosticism unwarrantably present as ge
neralizable procedure what are in fact contingent knowledge-political
attempts to reposition various fields of controversy. They present a m
ethodological version of what remains a rather exceptional case in a l
arger class of 'third positions: which define various types of situate
d distance and various mixtures of detachment and involvement An inspe
ction of influential symmetrical 'translations' of the dispute between
Hobbes and Boyle, and of recent 'epistemological chicken' and 'captur
ing' debates, reveals some of the epistemological and political hazard
s which afflict S&TS's convulsive forward push of the 'symmetry fronti
er' Given such perils, a case is made for 'weak asymmetry' with regard
to the issues of truth vs error, science vs politics, and culture vs
nature.
