The article makes the case that our "emotional systems" can be understood as an effective way of internalizing and responding to our experiences in a complex world. Maybe this is obvious but I think equally important is the emotional interplay between people, and the dynamics of that larger emotional system. Emotions are like a protocol that humans use to communicate their mental states to each other. If emotions were just about understanding the world, there would be no reason for humans to express them visibly & audibly. A little bit of occasional anger can effectively communicate that someone has crossed a line. Laughter is positive feedback. etc. etc.
