It struck me that comment was excellent and insightful, and was only possible because both the commenter and myself were once taught something that neither of us uses in our day jobs, and may never have learned through any normal self-driven persuit.
The more I hear about this book the more ignorant it sounds. The benefits of having a significant, as large as possible, portion of everyone being at least somewhat educated on a wide range of basic ideas (not facts so much) isn't quantifiable. It's effects are in countless infinite small thimgs that no one can tally.
It's not good enough that some small percent of people would always be educated, because those people still have to interact with everyone else. We already have a bad enough problem of people simply not even understanding what other people say, and therefor not crediting or respecting it at all and going with their feelings on everything.
