“How to Win Friends and Influence People” is possibly the most famous book of the 20th century, yet it’s also one of the book’s most routinely ridiculed by people who think they’re clever. Why on Earth would an intelligent person need help with something as basic as that? Intellectuals have mocked it down the decades, believing that good people don’t need to win friends, they already have them and they don’t need to influence them, they just need to say important things. However, Dale Carnegie, born in 1888 into a poor farming family in rural Missouri, had a different view. He left school in his teens and rather than attend University, he spent his years selling bacon and soap to people living in isolated ranches. He then got involved in adult education and spent tens of thousands of evenings giving talks to small audiences in out of the way towns. With over prominent ears and a prosaic haircut, Dale Carnegie was almost the anti-type of what we imagine a great and centrally important writer might be like. In 1936, when he was in his late 40s, he summed up his views on being nice in a book that was ridiculed by intellectuals then and now - “How to Win Friends and Influence People”. The issues that Carnegie addresses are utterly basic - we spend vast parts of our lives trying to build relationships, hoping to get others to appreciate who we are, to understand us and grasp what we have to offer them, and yet our efforts are very often far from successful. Carnegie pinpointed things we desperately need to know and get good at, but which have been largely neglected by previous writers. What Carnegie suggests sounds entirely like Common Sense - smile, remember someone’s name, listen to them, think about what they want, don’t make your success come at the price of theirs, don’t tell others they’re wrong, get to understand and appreciate why they think as they do, especially if it strikes you as misguided. Yet, these are precisely the things we generally forget to do. Carnegie recognized with astonishing Clarity how naive sounding the advice we need often really is. Our culture wants us to imagine that what we need to know are very complicated things - a university will make sure its science students understand the theory of relativity or that its Humanities graduates are acquainted with Foucault’s views on 19th century prisons. We’re quite good at abstruse things, and yet we trip up on issues that are diametrically opposite in character, that are simple, emotional and interpersonal. They involve not demonstrating how much we know, but rather showing how much we like other people. Knowledge of the truth is a tiny fraction of what it takes to make the truth effective in the world. What we need in Spades is charm and an ability to persuade others that we are on their side. It’s never enough to feel heartily Superior or as unfortunately pessimistically inferior and simply wait for others to come to us. We have to master the art of winning people over to our side, and will be persuaded to change our minds only by people that we like and who we feel love and understand us, that is, by people who’ve taken Dale Carnegie’s vital lessons to Heart.
