“My view is this: We teach nothing. We do not teach physics nor do we teach students. (I take physics merely as an example.) What is the same thing: No one is taught anything! Here lies the folly of this business. We try to teach somebody nothing. This is a sorry endeavour for no one can be taught a thing.What we do, if we are successful, is to stir interest in the matter at hand, awaken enthusiasm for it, arouse a curiosity, kindle a feeling, fire up the imagination. To my own teachers who handled me in this way, I owe a great and lasting debt.”
