"For indeed my life is a perpetual question mark – my thirst for books, my observations of people, all tend to satisfy a great, overwhelming desire to know, to understand, to find an answer to a million questions. And gradually the answers are revealed, many things are explained, and above all, many things are given names and described, and my restlessness is subdued. Then I become and exclamatory person, clapping my hands to the immense surprises the world holds for me, and falling from one ecstasy into another. I have the habit of peeping and prying and listening and seeking – passionate curiosity and expectation. But I have also the habit of being surprised, the habit of being filled with wonder and satisfaction each time I stumble on some wondrous thing."
