Not long ago I received an email marketing missive meant for my late mother.
"Dear Amazon.com Customer," it began. "We've noticed that customers who have purchased or rated 'Rolling Away the Stone: Mary Baker Eddy's Challenge to Materialism' have also purchased 'Stone Me: The Wit and Wisdom of Keith Richards.' For this reason, you might like to know that 'Stone Me' is now available in paperback."
I was interested, in fact. But I was also skeptical of the pairing that this algorithm offered. Was there really a massive crossover audience for readers of a 500-page intellectual biography of the woman who founded Christian Science and a sampler of bon mots from the guitarist who co-founded the Rolling Stones? I had to find out.
Sleuthing through works by the woman and man responsible, respectively, for "Science And Health," "With Key To The Scriptures" and "Sticky Fingers," offered some pretty stunning insights, especially when you look at their words line by line. For example:
Mary Baker Eddy: "Divine love always has met, and always will meet, every human need."
