“Nothing makes any difference as long as some one is listening while they are talking. If the same person does the talking and the listening why so much the better there is just by so much the greater concentration. One may really indeed say that that is the essence of genius, of being most intensely alive, that is being one who is at the same time talking and listening. It is really that that makes one a genius. And it is necessary to be at once talking and listening, doing both things, not as if there were one thing, not as if they were two things, but doing them, well if you like, like the motor going inside and the car moving, they are part of the same thing.”
