Theodore Schatzki’s analysis of dispersed and integrative practises implies that normativity arises, not at the higher order level of rules, or practises, or institutions (at least not exclusively), but at the very basic level of individual interaction with the environment. This view is reinforced by various analyses of know-how and expertise.
What is interesting to note, especially with regard to Davidson and Gadamer, who actually are in the same boat here, is that uninterpreted content then plays a key role. We need such content in order for normativity to have a basis on which the language-based practises may build.
For Gadamer this is anathema: all experience is linguistic and exists only in and through language. For Davidson it presents a problem too, although it may not be immediately obvious that it does. For doesn’t Davidson avail himself of a primitive causal relationship between the world and us? And doesn’t he reject any form of mediation (linguistic or otherwise) between ourselves and the world?
But unmediated content is not the same as uninterpreted content as we use the phrase here. For in Davidson’s view our causal interaction with the world results in beliefs, and beliefs and (sentence) meanings are indistinguishable in terms of structure and content. So Davidson’s unmediated content is highly structured, in such a way that it is immediately expressible (given a suitably expressive language, of course): definitely not the uninterpreted content of everyday expertise. In fact Davidson seems committed to the same kind of linguistic view on experience that Gadamer embraces explicitly.
