Richard Dawkins: Emotions Depend for their Existence on Brains

What about things like jealousy, joy, happiness and love? Are these not also real? Yes, they are real, but they depend for their existence on brains. Human brains, certainly, and probably the brains of other advanced animal species, such as chimpanzees, dogs and whales too. Rocks don't feel joy or jealousy. And mountains do not love. These emotions are intensely real to those who experience them, but they didn't exist before brains did. It is possible that emotions like these, and perhaps other emotions that we can't begin to dream of, would exist on other planets. But also if those planets also contain brains, or something equivalent to brains. Who knows what weird thinking organs, or feeling machines may lurk elsewhere in the universe?
