It teaches you how to think

The classic argument for a liberal arts education is that it teaches you how to think.

Maybe true. But it feels strange to contrast. Does an engineering degree not teach you how to think? Does a earth sciences degree not teach you how to think?

In short, I don’t think knowing how to think has anything to do with the content. I think it has to do with the process of knowledge acquisition and application.

You can teach any content area with a focus on the meta skill of knowing how to think. It’s unfortunate that it isn’t done more.
