On this day in 1679, dueling was outlawed in England. The satirist Jonathan Swift, today's author, said he regretted this because dueling was a good way to rid the country of bores and fools.
In any event, today's reading is "A Treatise on Good Manners," and Swift observes that "pride, ill nature, and want of sense are the three great sources of ill manners." Thus, "good sense is the principal foundation of good manners." Spot on, I'd say.
