"Growing up, we experienced minor paradigm shifts — in sights into the principles of geometry, for instance, or a game, or a sudden broadening of our political or religious beliefs. Each insight enlarged the context, brought a fresh way of perceiving connections. The opening up of a new paradigm is humbling and exhilarating; we were not so much wrong as partial, as if we had been seeing with a single eye. It is not more knowledge, but a new knowing."
