Lots of philosophers have tackled the question of happiness going back to ancient Greece, and there are two main types of happiness according to ancient Greek philosophers as far as I can tell: hedonic and eudaimonic. Can you explain the difference? Hedonic happiness is what a lot of laypeople mean when they say happiness — just a sense of good feeling. Often when we’re thinking of hedonic pleasure, we’re thinking of the really basic stuff: good food, good sex, a feeling of accomplishment. Eudaimonic happiness is bigger. It’s about living a good life. Happiness that comes not just from your own success, your own pleasure, but from other people and from building character. If you look back at the ancient folks like Aristotle, they knew about both, but when push came to shove they were like, Go for the eudaimonic.
In ancient Greece, the big philosophical debate was also if happiness was nature or nurture. What does science say? Are certain people more predisposed to be happy? The way scientists study this is they do these classic studies with twins, and what they generally find is that happiness is heritable. The important thing to know, though, is that the heritability factor is pretty low. It’s about the same rate as what you’d see for religiosity or risk-taking. If your parents were super religious, maybe you’re more likely to be super religious, but it’s not set in stone. That’s the message of happiness: There’s probably some component that’s a little built in, but so much more of it is under our conscious control.
So we can learn to be happy? That’s the premise of my work...
