"Science investigates; religion interprets. Science gives man knowledge, which is power; religion gives man wisdom, which is control. Science deals mainly with facts; religion deals mainly with values. The two are not rivals."
"As my sufferings mounted I soon realized that there were two ways in which I could respond to my situation -- either to react with bitterness or seek to transform the suffering into a creative force. I decided to follow the latter course."
"No one really knows why they are alive until they know what they'd die for."
"If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward."
"On some positions, cowardice asks the question, is it expedient? And then expedience comes along and asks the question, is it politic? Vanity asks the question, is it popular? Conscience asks the question, is it right?There comes a time when one must take the position that is neither safe nor politic nor popular, but he must do it because conscience tells him it is right."
