Famous quotes containing the words source and/or tree:
“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)
“The wind had seized the tree and ha, and ha,
It held the shivering, the shaken limbs,
Then bathed its body in the leaping lake.”
—Wallace Stevens (1879–1955)
