"Our extraordinary evolution is driven by four key agents, which I describe in the following sections: Fire, Word, Beauty, and Time.
Fire describes how we outsource our energy costs to escape our biological limitations and extend our physical capabilities. Word investigates the role of information in our success: the use of language to accurately transmit and store complex cultural knowledge and communicate ideas between minds. Language is a social glue that binds us with joint stories, and enables us to make better predictions and decide who to trust based on their reputations. Beauty encapsulates the importance of meaning in our activities, which enables us to coalesce around shared beliefs and identities. Our artistic expression produces cultural speciation—tribalism between and within our societies—but also enables the trade in resources, genes, and ideas that prevents genetic speciation, while leading to bigger, better-connected societies with fancier technologies. Lastly, Time underlies our quest for objective, rational explanations for natural processes. The combination of knowledge and curiosity has driven us further than any other animal: we’ve developed the science to order the world and our place in it, becoming a connected global humanity."
"Information told through stories is far more memorable —22 times more, according to one study8—because multiple parts of the brain are activated for narratives. A list of facts only activates the language processing areas of the brain (Broca’s area and Wernicke’s area, where words are ascribed meaning). However, the same information conveyed through a story also activates the brain areas relevant to the narrative: if the story involves jumping or running, the motor cortex lights up; whereas if it mentions someone’s satin blouse, the sensory part of the brain is activated. Our brains react as though we were living the story and experiencing it firsthand. In this way, a storyteller can implant emotions, thoughts, and ideas into the minds of the audience, making them feel as though they are experiencing the same events. In fact, scans show that the storyteller and the listeners’ brains actually start to synchronize during storytelling—neurologists describe it as “speaker-listener neural coupling.”9 In other words, our brains have evolved to understand the world through narrative, making stories phenomenally powerful cultural tools—another mutually reinforcing geneculture coevolution. We weave narrative around all of life’s events, we make sense of the world and our own lives through stories, and many of us give authorship of this ongoing saga to supernatural creators."
