Superstition begets superstition.
T. M. Luhrmann in The New York Times, here:
LAST month I was in Accra, Ghana, to learn more about the African version of the new charismatic Christian churches that have become so popular in the United States and are now proliferating in sub-Saharan Africa, especially Ghana and Nigeria. What struck me was how much people spoke in tongues: language-like sounds (usually, repeated phonemes from the speaker’s own language) thought by those who use them to be a language God knows but the speaker does not.
I went to services that lasted three hours and for most of which people prayed in tongues. People I interviewed spoke about praying by themselves in tongues for similar stretches of time. They said they did so because it was the one language the devil could not understand, but what I found so striking was how happy it seemed to make them. “We love to speak in tongues,” one young Ghanaian woman told me with a laugh.
