Would a philosophy class really be good for high school students? Broadly speaking, I mean, not those 1 out of 100 students who are reading Sartre or Nietzsche (or even Dostoyevsky or Kafka) on their own, already, anyway.
A survey course, I mean, a 101-type of course, like you would see at a University. My feeling is that a course in introductory logic is the #1 most useful course that's missing in high school right now.
And again, there are going to be a few students for whom this would be redundant, but something like 99/100 students do not understand the machinery of thinking. If there's one thing my university education taught me, it's the machinery of thinking, carefully and rigorously. Most people never learn this, and I feel like this then precludes any understanding of anything advanced and even slightly abstract--and that includes both philosophy and (of course!) mathematics.
