And in making this attempt I must write from my own experience. No other method would be worthwhile. The mere exposition of a thesis would have little or no value. It is a case in which nothing can be helpful to others which has not been demonstrated for oneself, even though the demonstration be but partial. In writing from my own experience, I must ask the readers pardon if I seem egoistic or autobiographical. Without taking oneself too smugly or too seriously one finds it the only way of reproducing the thing that has happened in ones own life and which one actually knows...FROM THE BOOKS.
