Famous quotes containing the words john and/or ramsay:
““Our earth is degenerate in these latter days. Bribery and corruption are common. Children no longer obey their parents. . . . The end of the world is evidently approaching.” Sound familiar? It is, in fact, the lament of a scribe in one of the earliest inscriptions to be unearthed in Mesopotamia, where Western civilization was born.”
—C. John Sommerville (20th century)
“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)
