I recall, when writing at white heat, the utter amazement I felt on reading something I had written, and saying, "Now where did that come from?" Thoreau felt somewhat the same when he said, "It is like going fishing. One never knows what one will catch." Writing at its best must come from deep within, for there is where truth and originality lie; none comes entirely from the upper tenth of gray matter. It is when one reaches down into the dark realms of the past that great ideas surge forth.
