everything changes. everything stays the same
'The Renaissance (1350–1600) produced favorable conditions for charlatans. Old ways of thinking were cast aside, and it seemed that anything was possible.
A semiliterate village dweller might have been aware of a new discovery, but he or she was probably not sufficiently educated to distinguish fact from fiction. Charlatans could not have flourished without the support of a willing, naïve audience.
The extraordinary power of impostors is therefore only to be understood after a consideration of the minds and circumstances of their gullible victims, the crowds who sought them out, half convinced before a word was spoken.
If charlatans had not existed, villagers would have invented them.'
