1. The main point that Johnson is trying to make is you do stuff to build from it
2. 2. One thing he says to support this is the kids in algebra class. He says that over 99% of kids won’t use that stuff in their regular lives but it’s not about learning the math it’s about building up the mental muscles in your brain

3. another rhetoric appeal he is trying to get across is the logical standpoint of things. He is quoting John Dewey saying that, you can only learn from what you’re studying

4. Yes I do, it makes sense to me because people can’t really learn what they don’t know without studying and looking into it more than just a surface knowledge of the topic
