In order to give an impetus to the production of an apparatus of aesthetic concepts, in line with Deleuze and Guattari's claim to create new concepts for a changing world, this volume publishes statements and discussions of ten Concept on the Move workshops, as well as texts and discussions of the concluding Concept on the Move symposium. The integral outcome of the workshops, the symposium and the discussions does not, however, present some sort of blueprint for the future of visual art and aesthetics. If one wished to designate the Concepts on the Move publication in one notion at all that definitively could only be TOOLKIT. A TOOKIT in the sense of a great collection of ideas, topics, issues, notions, and concepts emerging in the 21st-century world of visual art and theory. They indeed could serve as an impetus for the construction and production of a body of theoretical work fit to understand today's technological, theoretical, and artistic developments in the art world. Are concepts on the move? Yes, they are, and they always will be on the great journey visual art takes them.
