Blood of Elves (The Witcher, #1)

by Andrzej Sapkowski

Intolerance and superstition has always been the domain of the more stupid amongst the common folk and, I conjecture, will never be uprooted, for they are as eternal as stupidity itself. There, where mountains tower today, one day there will be seas; there where today seas surge, will one day be deserts. But stupidity will remain stupidity.

When you know about something it stops being a nightmare. When you know how to fight something, it stops being so threatening.
