Hunter-gatherers have nothing akin to school. Adults believe that children learn by observing, exploring, and playing, and so they afford them unlimited time to do that.
The Sudbury Valley School and a hunter-gatherer band are very different from one another in many ways, but they are similar in providing what I see as the essential conditions for optimising children’s natural abilities to educate themselves. They share the social expectation (and reality) that education is children’s responsibility, not something that adults do to them, and they provide unlimited freedom for children to play, explore, and pursue their own interests. They also provide ample opportunities to play with the tools of the culture; access to a variety of caring and knowledgeable adults, who are helpers, not judges; and free age-mixing among children and adolescents (age-mixed play is more conducive to learning than play among those who are all at the same level). Finally, in both settings, children are immersed in a stable, moral community, so they acquire the values of the community and a sense of responsibility for others, not just for themselves.
Toys are not really as innocent as they look. Toys and games are preludes to serious ideas
