Conviction

"Convictions are more dangerous foes of truth than lies."

"My religious convictions and scientific views cannot at present be more specifically defined than as those of a believer in creative evolution."

"Patriotism is, fundamentally, a conviction that a particular country is the best in the world because you were born in it."

"A 'no' uttered from the deepest conviction is better than a 'yes' merely uttered to please, or worse, to avoid trouble."
