Fauconnet, 1903) -echoes in curious ways the current absence of influential sociological perspectives on human-nature relations.Representation is now a faded concept in sociology. It figures here and there, such as in Bourdieu's (1989) account of symbolic power, in Latour's (1993: 7) fierce rejection of the concept as depicting a collection of "minds-in-a-vat", or in cultural studies of representations as artifacts (see Calhoun, 1997). In any case, its meaning is often unclear or taken for granted, and its prominence is far from Durkheim's vision of collective representations as the essence of the sociological endeavor (Pickering, 2000: 2).This dissertation is an attempt to breathe new life into the concept of representation and to examine its suitability for studies of human-nature relations. To better understand ongoing knowledge conflicts and the role of social meaning in today's political battles over burning Amazonian forests, the devastating effects of petroleum extraction, melting poles, or the destruction of habitats of one million species (Tollefson, 2019), there is a need for clarification of what we mean by "knowledge conflicts." What is the "stuff" this knowledge is made of, and in what do these conflicts reside? Are they mere reflections of colliding material interests and struggles for control over natural resources, or does the study of representations of nature add something to the equation? If it does, how are culturally shared ideas related to social conflict? 101
