"American dreams are strongest in the hearts of those who have seen America only in their dreams." — Pico Iyer

Alas, those six unfortunate souls who have made their way through my books know that every one of them is about Emerson and Thoreau and their dark counters, Melville and Emily Dickinson. Try as I might, I can't get their inspirations, their challenges and sentences and wisdom and questions out of my head.

We all know how we can be turned around by a magic place; that's why we travel, often. And yet we all know, too, that the change cannot be guaranteed. Travel is a fool's paradise, Emerson reminded us, if we think that we can find anything far off that we could not find at home.

Travel, for me, is a little bit like being in love because suddenly, all your senses are at the setting marked 'on.' Suddenly, you're alert to the secret patterns of the world.

'Globalization' has become the great tag phrase, but when we talk about it, it's nearly always in terms of the global marketplace or communications technology - either data or goods that are whizzing around. We forget that people are whizzing around more and more. On them, it takes a toll.
