We travel, in essence, to become young fools again - to slow time down and get taken in, and fall in love once more.

In the past, Ive visited remote places - North Korea, Ethiopia, Easter Island - partly as a way to visit remote states of mind: remote parts of myself that I wouldnt ordinarily explore.

As a member of the mainstream media for many years, I've learned just one thing: never to trust anything I read in the mainstream media - not because of any agenda or deliberate dissimulation, but simply because it's filtered and comes very often from someone whose judgment I might not trust in other circumstances.

I take very seriously the sense of our living these days in a global neighborhood. And the first sensible thing to do in such circumstances, as well as one of the most rewarding things, is to go and meet the neighbors, find out who they are, and what they think and feel. So travel for me is an act of discovery and of responsibility as well a grand adventure and a constant liberation.

Perhaps the greatest danger of our global community is that the person in LA thinks he knows Cambodia because he's seen The Killing Fields on-screen, and the newcomer from Cambodia thinks he knows LA because he's seen City of Angels on video.

In terms of technology and science, tomorrow does know more than yesterday; but when it comes to emotions, living with uncertainty, terror, I'm not sure we know any more than Shakespeare did, or the Buddha. And the power of new things - the iPhone or Facebook - is so strong and intoxicating that we sometimes forget that none of them can fundamentally change our relation to ourselves and to what matters.

Everyone is a Wordsworth in certain moods, and every traveler seeks out places that every traveler has missed.
