Famous quotes containing the words physical and/or probability:
“There are those who believe Black people possess the secret of joy and that it is this that will sustain them through any spiritual or moral or physical devastation.”
—Alice Walker (b. 1944)
“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)
