Contemporary sociology is faced by a central problem of conceptualising and
rendering empirically operable the concept of difference without dissoluti
on into perpetual plurality on the one hand, and recourse to fixed hierarch
ical relations on the other. Drawing on attempts to operationalise research
categories within a research project on the health beliefs and behaviours
of South Asian mothers, the paper explores the difficulties of operating co
ncepts of difference at epistemological analytical and methodological level
s. For example, within the research there are difficulties in operationalis
ing concepts of local/global difference and differences between western and
non-western medical systems without fixing one in a privileged position re
lative to the other or without seeing them as necessarily always equal. The
research also raises questions of how to sample across multiple difference
and develop interview and writing strategies which do not fix relations be
tween researcher/researched in either equal or hierarchical relations. The
paper draws on attempts to cope with these problems. It engages with post-m
odern approaches to difference but stops short of complete deconstruction,
developing these approaches instead within a dialectical framework. A diale
ctical approach attempts to contextualise difference, recognising the inter
relationship and contradiction between research categories of difference, t
emporally locating hierarchies between them. Methodologically, it also stri
ves to develop an approach which steers a course in between a position of r
esearcher as 'expert' and a position where our knowledge of others is treat
ed as inconceivable.
