The school system isn’t wrong in the sense that it’s further from the truth than Karl Popper. It’s wrong like the Catholic Church was wrong in refusing to accept Galileo’s heliocentrism and in locking him up so as to protect their worldview.
Overt coercion is less likely to corrupt children’s interpretation of what is happening to them. But given that part of our self respect as parents taking our children seriously comes from being non-coercive, it might well be that the coercion we inadvertently engage in is interpretation-corrupting double binds. So we need to be particularly aware of the subtle mind-messing forms of coercion.
We believe that it possible for human beings, through conjecture, reason and criticism, to come to know and understand truths about the world, including truths about the human condition and about specific people, and including truths about matters that are not experimentally testable. We do not believe that we possess the final truth about any of these matters, but we do believe that our successive theories can become objectively truer—with more true implications and fewer errors.
Once one begins to see how extremely general this notion of conjecture and refutation is, then it begins to seem much more likely that learning always follows that pattern.
Understanding that knowledge grows through creative conjecture and inner criticism facilitates non-coercive interactions.
How you think people learn informs all your interactions with your children. If you view learning as a creative act in a critical-rational process, you will value highly the idea of consent in decision-making. If you believe people learn through divine revelation or by having knowledge poured into them, that will inform your interactions in a different way from if you think that they learn though conjectures and refutations: you may well think coercion necessary.
