I love John Holt. He and John Taylor Gatto were so hugely instrumental in our path to unschooling. I came across this quote today - one that I have read before - and wanted to share it. So simple and meaningful at the same time. Love it.
Once when John Holt was speaking to a school audience, describing his views on their structured curriculum, a student asked him, "But surely there must be something important enough that everyone should learn it?" He thought for a moment and replied, "To learn to say 'I'm sorry', 'I don't know', and 'I was wrong'."
