From the Nasa website:

Jack Stuster, author of Bold Endeavors: Lessons from Polar and Space Exploration, quoted Norwegian scientist and explorer Fridtjof Nansen as saying “The history of the human race is a continual struggle from darkness toward light. It is therefore to no purpose to discuss the use of knowledge. Man wants to know, and when he ceases to do so, he is no longer man.”

An updated version:
The history of the human race is a continual struggle from darkness toward light. It is therefore to no purpose to discuss the use of knowledge. We want to know, and when we cease to do so, we are no longer human.

I think I like the second one better because it doesn’t set the speaker apart from us. More on the latest addition to my heros list: Fridtjof Nansen
