In this wonderful talk, Peter Gray talks about education and how modern schools prevent True exploration and natural learning. There is something wrong with the modern world we live in. That sense of wrongness is the most vivid when one observes children behaving in a distorted way. I mean all that whining you hear all the time on the streets form children manifesting "I want ...". The situation when an adult can communicate with a child in a reasonable way is so rare that the whininess of children is perceived as a norm. But as Peter Gray points out it's a norm in our culture only: "After the talk, a graduate student came up and said to me that she was doing her dissertation on whining. She had this view about that there is a universal tone to whining. And she wanted to know what hunter gatherer's whining sounds like. And so I said I don't know, I've never lived in a hunter-gatherer culture but let me ask my friend Gilda Morales. So I went and asked Gilda Morales and she had to stop and think, she said "I lived with these people and interacted with the children for months and months and I don't think I ever heard a child whine. They didn't have anything to whine about"."
