I don’t make up marvelous travels. I only try to express –as clearly as possible– the thoughts and feelings many people have. (…) when I sit down with these subjects my aim is clarity. I’m really trying to clear some of the muddle from my own brain –my brain being a very muddled place indeed. Sometimes I think my whole professional life has been based on this hunch I had, early on, that many people feel just as muddled as I do, and might be happy to tag along with me on this search for clarity, for precision. I love that aspect of writing. Nothing makes me happier than to hear a reader say: that’s just what I’ve always felt, but you said it clearly. I feel then that I’ve achieved something useful.
