“Anything one man can imagine, other men can make real.”

“The truly free man is the one who can turn down an invitation to dinner without giving an excuse.”

“While there is life there is hope. I beg to assert...that as long as a man's heart beats, as long as a man's flesh quivers, I do not allow that a being gifted with thought and will can allow himself to despair.”

“Why lower oneself to taking pride from being American or British, when you can boast of being man!”

“With time and thought, one can do a good job.”

“And this accident came about...?"Through nature's unpredictability not man's incapacity. No errors were committed in our maneuvers. Nevertheless, we can't prevent a loss of balance from taking its toll. One may defy human laws, but no one can withstand the laws of nature.”
