The informational age that we live in today is interesting. We feel (at least I feel) a great urge to share the knowledge we gain from reading, interacting with smart people, and by simply being present in the world. Personally, I have also almost always felt that I was supposed to have some type of an opinion about any given topic. The world, it seemed, always wanted me to say one thing or another and have thoughts about one thing, even if I didn’t know much about it.
In Letters From a Stoic Seneca briefly touches on this same point. He often started many of his letters in a build-up to the advice that he was passing along. One of those sections opening one of his letters read, “Nothing will ever please me, no matter how excellent or beneficial, if I must retain the knowledge of it to myself. And if wisdom were given me under the express condition that it must be kept hidden and not uttered, I should refuse it. No good thing is pleasant to possess, without friends to share it.”
Robin Hanson and Kevin Simler, in their book The Elephant in the Brain, explain why Seneca felt this way 2,000 years ago and why I feel this way today. They explain that communication is not really about sharing valuable information. If it was, we would only want to share our valuable information if someone else shared their valuable information first. In a sense, our society would be kick-ass at listening, and Ted Talks probably wouldn’t be a thing. What is really happening in our social worlds is that we evolved to show off. We want to show people how much useful information we have, what unique insights our experiences have given us about the world, and what new knowledge we have. Possessing new, unique, and helpful information 50,000 years ago meant that we could help ourselves and others survive. Sharing that information freely showed an abundance of knowledge and resources on our part, and made us a useful ally which helped us thrive in social groups.
We probably should not turn against this urge to share useful knowledge. Books, insightful anecdotes, and Ted Talks seem to have worked out pretty good for humans in terms of sharing and passing along useful information. We should recognize, however, that often the desire to share our knowledge is not as altruistic as Seneca might have you think. Our urge is a bit self-serving, so before we post on Facebook about how obviously correct our political views are relative to others, we should recognize the evolutionary forces driving us to have an opinion and encouraging us to blast those ideas out into the world in an attempt to show off. Ultimately, if you are going to share your thoughts, try to spend some time developing them so that they provide real value to the person who may encounter them.
