I've written about hilaritas elsewhere, but I thought I'd bring it up here for the benefit of Boing Boing readers who may not be familiar with the concept. I was introduced to the term via the work of Robert Anton Wilson. The more common hilarity springs from the same root. Hilaritas was a Roman goddess of rejoicing and good humor. She appeared on Roman coins from from the time of Hadrian until the late 3rd century AD. Hilaritas was a Roman public virtue, something that people were supposed to strive to exhibit and inspire others with. Wilson was keen on this word as he thought it perfectly expressed a rare quality of being that revealed a special kind of person. He defined hilaritas as “profoundly good natured” and made clear that, for him, it was more than just being happy or having a good sense of humor. I've also seen it defined as “being of pleasant spirits.” There's a kind of cosmic it-factor involved. People possessed of hilaritas are people you're drawn to because they have something indefinable that you want, a kind of playful knowing about the world. They seem to be having just a bit more fun on the slip'n slide flow of the Tao than the rest of us. Santa Claus has hilaritas. Bugs Bunny. Hotei. Mark Frauenfelder. And, of course, our dearly-departed Bob Wilson (Eris playfully unrest his soul) embodied this quality. My life has been a quest to surround myself with as much hilaritas as possible. It's ultimately hard to define, but (as they say) like pornography, you know it when you see it.
