If I had one this might be it:
From a radio interview with Gertrude Stein in the Fall 1990 issue of The Paris Review. The interview, conducted by NBC reporter William Lundell, was broadcast on November 12, 1934.
Lundell: But how is the reader supposed to know what you are thinking about?
Stein: The reader does know because he enjoys it. If you enjoy you understand and if you understand you enjoy. What you mean by understanding is being able to turn it into other words but that is not necessary.
