Making children sit in a chair - under threat is evil. "Discipline" ? What is that ? Tribal children - never beaten, educate, forced to do something, how come they don't all become lazy or "antisocial" ? Because their nature is not "lazy" or "antisocial" and they do not need "discipline". They need freedom to develop, to test the world around by themselves.

"The Continuum Concept". The author describes some tribe in Venezuela - a child age 11 was free to decide for himself where to go, to stay with her and the crew or whatever. Even if that meant going some 3 days alone with them, nobody forced his will on him. His destiny was his own. That's how you build self trust - by having the freedom to to things on your own. As a child. That's how I know I gained self trust. Later as an "educated", molded, broken , brainwashed adult is much harder. You need psychotherapy and stuff.
How school should be : you have the teacher (who knows something from everything, only at college level you have separate teachers). Children go to school and sit where they like. Nobody says anything if they go outside and play. (A playground somewhere in nature would be best).
But children are curious. So at first the teacher will tell them stories, even teaching them history and stuff about our world - but in the form of a story. Then he can show them other stuff, to read, to calculate, and let them freely experiment with it. They stay at school as long as they like. And I am sure they would want to stay there
They will make friends there, they can play or do interesting stuff. Free.
(By free I mean free to come and go as they chose). All their friends will be at "school" playing - learning new stuff, I am sure the social and curious nature of children will make them want to be there.
Then the teacher starts telling them about everything : math, biology, chemistry and so on. Gives them books to read. Let's them chose what they like.
No grades, no tests, no schedule. Children can compete among themselves - only if they want to.
How long does school last ? As long as a child wants to. Then there will be "college" , after a child has chosen (if he has chosen) something he likes, and after he read some books about it, he goes to the university he wants. Here things are much more specialized - but he has the same freedom. Yes - simple freedom to sit anywhere, go anywhere, and come and go as he pleases. In the middle of the class. This is freedom. This forms character, to be able to decide for yourself. Not freedom like "sit here or there, but sit, do not dare to say you leave !". That is molding, and it's evil. To make the child feel he is too stupid to decide such a simple thing on his own. To make him doubt himself and make him ready to accept whatever he is told by "the
smarter people above"
In the end this "education" will produce anything but the worker consumer of today. Will probably produce a modern tribe, and a gift economy , no boss - servant relations, but that's something else.
