Anarchy
If I look at my work from an anthropological angle, as in, a process of thinking about and actively examining questions such as: Authority, optional models for groups organisation, governance modalities, political and social structures, economic models, resources management and so on, the way I would define it then, would be something along these lines:
A commitment, through a choreographic practice, to the idea that it can be possible to have a society based on principles of self organization, voluntary association and mutual aid.
Which, in some ways, is the short and simple definition of Anarchy as a social model.
