Huxley on Subconscious Persuasion

Aldous Huxley in Brave New World Revisited:

Years ago, in Central America, I observed an example of persuasion-by-association which filled me with an appalled admiration for the men who had devised it. In the mountains of Guatemala the only imported art works are the colored calendars, distributed free of charge by the foreign companies whose products are sold to the Indians. The American calendars showed pictures of dogs, of landscapes, of young women in a state of partial nudity. But to the Indian dogs are merely utilitarian objects, landscapes are what he sees only too much of, every day of his life, and half-naked blondes are uninteresting, perhaps a little repulsive. American calendars were, in consequence, far less popular than German calendars; for the German advertisers had taken the trouble to find out what the Indians valued and were interested in. I remember in particular one masterpiece of commercial propaganda. It was a calendar put out by a manufacturer of aspirin. At the bottom of the picture one saw the familiar trademark on the familiar bottle of white tablets. Above it were no snow scenes or autumnal woods, no cocker spaniels or bosomy chorus girls. No—the wily Germans had associated their pain-relievers with a brightly colored and extremely life-like picture of the Holy Trinity sitting on a cumulus cloud and surrounded by St. Joseph, the Virgin Mary, assorted saints and a large number of angels. The miraculous virtues of acetyl salicylic acid were thus guaranteed, in the Indians’ simple and deeply religious minds, by God the Father and the entire heavenly host.
