But arguing itself tends to get a bad rap. It’s blamed for everything from political polarization to marital breakdown. In his 1936 classic, How to Win Friends & Influence People, Dale Carnegie wrote: “I have come to the conclusion that there is only one way under high heaven to get the best of an argument—and that is to avoid it. Avoid it as you would avoid rattlesnakes and earthquakes.” I take issue with Carnegie’s conclusion—if he were still alive, maybe we could debate it.
