"if you found me a culture that did was I just did"
But you don't find that, while you find religious cultures through all of recorded human history. And not just random cultures and random texts, but texts that lead cultures to succeed and replace older texts that offered less to the people and species. Harris isn't appreciating how we got to this point as a species by treating religion in such a manner.
Cuisine serves a purpose to human society. If you think of the concept of meals and family meals, namely the invention of soup,that's group living that takes multiple ingredients and then improves the yeild of that hunting/gathering by putting them in a pot with water and fire. So you get large meal for a group, creating social interaction and unity, while allowing uninterrupted work beyond. Maybe you even increase play time by having that group meal, which benefits you emotionally and socially.
So you can look at food and extract something out of it, but you got to do so sincerely and intelligently. Not that flying spaggheti monster sort of take Harris has there.
