Just kidding! It’s a ridiculously complicated question, to which I’ve only ever seen educated guessing and speculation, and those explanations lack satisfying answers. Really, most of the articles claiming to tackle he question just lead to more questions within.
And why not? We don’t really understand why we do it, why it compels is, why so many of us want to defy the long odds of scarce audiences, fans, and followers to make it a centerpiece of life.
Maybe the questioning is the most important. Answers are necessary for science, explanatory power and evidence for claims and phenomena. They aren’t so important for art, essentially because it’s mysterious and strange.
So here’s a mere guess. What we know is that humans are driven to endlessly reinterpret the world outside our minds and present them to others. We keep returning to the mysterious power of it. And entertaining a mystery is not only fun, it’s rewarding.
It’s not that life on its own isn’t enough. It’s that art gives us the creative power we see around us all the time in nature. We’re the animal who questions, and art reaches questions only dreamed of in other fields.
