A number of years ago I had some experience with being alone. For two succeeding years I was alone each winter for eight months at a stretch in the Sierra Nevada mountains on Lake Tahoe. I was the caretaker on a summer estate during the winter months when it was snowed in. And I made some observations then. As time went on I found that my reactions thickened. Ordinarily I am a whistler. I stopped whistling. I stopped conversing with my dogs, and I believe that the subtleties of feeling began to disappear until finally I was on a pleasure-pain basis. Then it occurred to me that the delicate shades of feeling, of reaction, are the result of communication, and without such communication they tend to disappear. A man with nothing to say has no words. Can its reverse be true- a man who has no one to say anything to has no words as he has no need for words? ... Only through imitation do we develop toward originality.
