Famous quotes containing the words proof and/or fence:
“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)
“Thus thinne and lean without a fence or friend,
I was blown through with ev’ry storm and winde.”
—George Herbert (1593–1633)
