Nobody climbs mountains for scientific reasons. Science is used to raise money for the expeditions, but you really climb for the hell of it.

I like to think of Everest as a great mountaineering challenge, and when you've got people just streaming up the mountain - well, many of them are just climbing it to get their name in the paper, really.

I'm a very, very modest person and with limited abilities. I do have the wish to succeed in anything I undertake, and that does help out, but, in general, there are so many other people who are skilled in their field that I feel very ordinary.

I've often thought about that and the only suitable member to join me on that climb [to Everest] was George Lowe: he was strong, a good man on a mountain, with a great sense of humour, and I liked that. I think George and I could've done that together ... I've probably never told George that.

If the going is tough and the pressure is on, If the reserves of strength have been drained and the summit is still not in sight, then the quality to seek in the person is neither great strength nor quickness of hand, but rather a resolute mind firmly set on its purpose that refuses to let its body slack or rest.

I think that a good mountaineer is usually a sensible mountaineer.

It's not a real adventure when you have to pay for it.
