Frank Borman

Capitalism without bankruptcy is like Christianity without hell.

Exploration is really the essence of the human spirit.

It's a vast, lonely, forbidding expanse of nothing rather like clouds and clouds of pumice stone. And it certainly does not appear to be a very inviting place to live or work.

Exploration really is the essence of the human spirit and to pause to falter to turn our back on the quest for knowledge is to perish.
