Project area C "Concepts" comprises those projects that investigate actions and artefacts which explicitly reflect upon themselves, which seek a specific artistic profile in opposition to other concepts or which are marked by conceptual claims of their own. In comparison to project areas A and B, this area includes projects that are concerned with the most obvious aesthetic statements. Accordinly, in this area projects are working together that focus on actions and artefacts in which aesthetic concepts are dealt with discursively. Research in this area has in common that (developing) concepts can be clearly identified though they may not yet be available to existing terminology. This is why the individual research projects of area C are clearly related to, and connected by, central aesthetic problems, traditions and norms of the autological dimension.
