Edmond Hamilton,
The knowledge machine
(1948)
“ When our sale of science-subjects began to fall off, we switched our advertising to concentrate on art. We made expert knowledge of art all the rage. Sure enough, people came in by thousands to have their science knowledge erased so they could take on a cargo of art.Carter had worked out advertising that made young people good repeat customers, too. If they didn't feel satisfied in their professions, why not try a new one? ”
