Famous quotes containing the words probability and/or spaces:
“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 (16861743)
“Though there were numerous vessels at this great distance in the horizon on every side, yet the vast spaces between them, like the spaces between the stars,far as they were distant from us, so were they from one another,nay, some were twice as far from each other as from us,impressed us with a sense of the immensity of the ocean, the unfruitful ocean, as it has been called, and we could see what proportion man and his works bear to the globe.”
—Henry David Thoreau (18171862)
