Gleaning the wisdom of those who have come before us is a practice as old as time, but in quoting the geniuses of the past, we often misattribute their wisdom. Pat O'Connor, author of Woe is I, says that a few people in particular get a disproportionate number of quips attributed to them.
"People who are known to be wits, and if they're famous, often an anonymous quote will be pinned on them," says O'Connor. "For example, Twain is often credited with saying, 'Age is an issue of mind over matter. If you don't mind, it doesn't matter.' Well no, he didn't say that."
