Quote by Tarski, Alfred

"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."

"I've seen a lot of things in my time."

"That's how we archaeologists tell time."

"We must learn from history or be doomed to repeat it."

"Every artifact tells a story."
