“We have not succeeded in answering all our problems. The answers we have found only serve to raise a whole set of new questions. In some ways we feel we are as confused as ever, but we believe we are confused on a higher level and about more important things.”
I read this quote on a wall on Mark Cane’s office at LDEO (Columbia) many years ago and always wondered where it came from. He found it as an epigram in a book on ‘Stochastic Differential Equations‘ by Bernt Øksendal where it is sourced to a sign outside the mathematics reading room at Tromsø University. The actual source appears to be a 1951 report on an education workshop by Earl C. Kelley, a professor at Wayne University (sleuthing by QI).
