Famous quotes containing the words proof and/or string:
“The source of Pyrrhonism comes from failing to distinguish between a demonstration, a proof and a probability. A demonstration supposes that the contradictory idea is impossible; a proof of fact is where all the reasons lead to belief, without there being any pretext for doubt; a probability is where the reasons for belief are stronger than those for doubting.”
—Andrew Michael Ramsay (1686–1743)
“Supposing everyone lived at one time what would they say. They would observe that stringing string beans is universal.”
—Gertrude Stein (1874–1946)
