Practice 6　　With a high degree of specialization, the frontiers of knowledge are steadily being pushed back more rapidly than ever before. But this has not been achieved without considerable cost. The scientist, who outside his own particular subject is little more than an idiot, is a modern phenomenon; as is the man of letters who is barely aware of the tremendous strides that have been made in technology. Similarly, specialization has indirectly affected quite ordinary people in every walk of life. Many activities which were once pursued for their own sakes are often given up in despair: they require techniques, the experts tell us, which take a life-time to master. Why learn to play the piano, when you can listen to the world’s greatest pianists in your own drawing-room?
