John Cage's Lecture on Nothing was included in his first and most important collection of writings, Silence, in 1961. With its litany of zen-like aphorisms and observations, and increasingly obsessive repetitions that seem to have come straight out of Gertrude Stein, it is a perfect encapsulation of the artistic world Cage invented (he would probably have said found) for himself.
Published as a part of NO PUEDO magazine #1 (coming out on November '16) thanks to the John Cage Trust and the Wesleyan University Press.
