Creative self-criticism in science and art (Stolen from Beethoven's sketch books)
I should like first ofall to express my thanks for the kind invitation to give the opening address at the Salzburg Festival. This is a great honour. The invitation came as a complete surprise, and it was even somewhat disturbing. Ever since 1950 my wife and I have led a secluded life in our house in the Chiltem Hills. We have no television and no newspaper, and we are completely absorbed by our work. My work is concerned mainly with an abstract subject: the problem ofhuman knowledge and, in particular, ofscientific knowledge. That hardly qualifies me to give an opening address at the Salzburg Festival.
