The Aphorisms of Irsee is a collection of definitive statements on the nature of art by the artist Clive Head and the writer Michael Paraskos. The aphorisms were formulated whilst Head and Paraskos were teaching at a summer art camp in Irsee, southern Germany. Sometimes controversial, often funny, the aphorisms are designed to challenge our understanding of art by defining its essential characteristics. Head and Paraskos do this not only in terms of the question what is art? but the equally important question, what are the conditions in which art can appear? With a new introduction for the third edition by Michael Paraskos, the Aphorisms of Irsee are radical, challenging and thought provoking, and a joy to read. They set out a new agenda for art in the twenty-first century.
