 Naturalist work on constructionist approaches to representations can be grouped according to the debate the naturalist is addressing. Naturalists addressing the challenge posed by social construction to the authority of science have attempted to respond to this challenge in a variety of ways that pit various versions of realism and empiricism against constructionism (e.g. Boyd 1992; see  Social Dimensions of Scientific Knowledge).  Because naturalists are typically committed to science as a central, if fallible, avenue of knowledge about the world (i.e. some variety of epistemic fundamentalism), naturalists will want to explain how this can be if, as social constructionists about scientific representations note, empirical observation is theory-laden and scientific theories are themselves subject to massive social influences.
