I guess I don't try to justify climbing or defend it, because I can't. I see climbing as a compulsion that, at its best, is no worse than many other compulsions - golf or stamp collecting or growing world-record pumpkins.

Military investigations are designed not to find anyone guilty.

Why climb? That's a question that baffles me. It perplexes me. I really asked that a lot on Everest. I can't justify it. I can't say it's for a good cause. All I can say is look at the history of exploration: it's full of vainglorious pursuits.

Antarctica has this mythic weight. It resides in the collective unconscious of so many people, and it makes this huge impact, just like outer space. It's like going to the moon.
