I haven't read it, but I have read quite a bit of other things by John Holt.

He is known mainly as a theorist of education (the title of the above-quoted book may be a reference to a teacher trying to plan class activities) but he would probably say that he was interested in learning, and interested in education only inasmuch as it helps or hinders learning. He is the primary initiator of the "unschooling" philosophy of homeschooling.

I have posted some other John Holt quotes elsewhere in this post's thread.
