This paper proposes “access” as the internal driving principle of ecoart and analyzes cases of ecoart that take the earth as their medium. As a principle running through existing ecological discourse, access finds its analogous conditions—access, network, coupling, connection and relation—in the theories of J. Rifkin, G. Bateson, and H. Maturana and F. Varela, as well as D. Haraway, N. Luhmann, J. Burnham, and N. Bourriaud. From this perspective, Alan Sonfist empirically accesses social and historical realities through physical contact with the earth, while Unmake Lab stages ecological disturbance with the recursive input and output of data. By repeating feedback within their respective media and methodologies, these practices demonstrate that access is both the premise and the operative principle of multiple relations among various subjects. Accordingly, “Access-Aesthetics” attends not to a consequentialist application but to the process of junction and generation among the countless instances of information that produce difference; through this process, it establishes an epistemological and practical foundation for the symbiosis of nature-human-machine-art.
