"The sentence 'snow is white' is true if and only if snow is white."

"Logic is the study of the principles governing valid inference."

"Truth is a property of sentences, not of the world itself."

"Mathematics is the art of reducing any problem to previously solved problems."

"Never let fear stop you from chasing your dreams."

"Courage is being afraid but doing it anyway."

"Sometimes you gotta do what you gotta do."

"Sometimes you have to be the monster to stop the monsters."
