The Growing Importance of Folklore
For a new perspective on what I call "folk knowledge" or what might be categorized as "folk culture" instead of folklore, since it is more correct and encompassing, we need only look to authors like Adrienne Mayor. Through long, independent research, she discovered that the ancient Greek myths about monsters were actually stories about people finding beds of fossilized bones of ancient creatures. These "geomyths" as they are called convey, real, true, factual information and represent a kind of scientific method even preliterate people engaged in, despite conveying them in a dramatic way.
In Pollan's book, food culture or food ways, as a folklorist would call them, represents knowledge that the best scientific nutritionists failed to see, take advantage of and learn from. The nutritional systems which evolved out of thousands of years of trial and error passed down by mothers through the generations, amounted to a better set of food choices than did a hundred years of scientific rational nutritionism.
In books like Blink, Albion's Seed and Stuff of Thought, we are beginning to see how our unconscious knowledge and folk knowledge shapes our decisions and opinions, sometimes without our knowledge, absorbed by osmosis through our culture. Frequently, this knowledge proves more accurate and useful than scientific rational knowledge, especially when the science is new, incomplete and arrogant, such as nutritional science.
If you don't think you participate in folklore or that it has a place in the modern world, take a look at Sadobabies, a film about urban homeless kids. Or Music District, a film about urban music. Everyone creates folklore, everyone lives in a folk culture, in reality, many folk cultures, for each folk way is a folk culture, you probably practice a food way, a work way, a everything way. You also build new ways out of old ones, from both things learned from your parents and neighbors and scraps of commercial culture. Rap is a folk culture. Commercial rap feeds into rap, and the folk culture cycle goes on. At work, if you are a programmer, you probably learned many things that are not in books on coding. This is "programmer lore" and is a folk culture and represents folk culture, which shapes the software we use in daily life, that controls elevators and space shuttles. If you don't think folklore affects your life, think again the next time you're riding an elevator.
