Science(s) which, when and whose? Probing the metanarrative of scientific knowledge in the social construction of nature

The role of ‘scientific knowledges’ in the social construction of nature(s) and realities has become a focal point of deconstruction and debate in both geography and science and technology studies over the past decades. In this article, I demonstrate that many authors have constructed a metanarrative of ‘science’ as a discursive strategy for their critiques of society. Science is portrayed as a homogenous activity with its ‘products’ implicated in various aspects of poltical-economic-social exploitation/oppression. This metanarrative belies the contempo-rary complexity of scientific endeavor and its diverse epistemic cultures. Suggestions to clarify the epistemologies of scientific knowledges and arbitrate between competing knowledges are presented.
