One of the problems I have faced in preparing my up-coming Columbia lectures is that there is simply not enough time to say everything I want to say in the three remaining seminar meetings devoted to Marx. Obviously one solution is to refer the students to the books I have written, but I was concerned that I might scare them away from the first book, Understanding Marx, if I mentioned that it had math in it.
Well, some years ago when I was working pro bono at Bennett College, an HBCU in Greensboro, I surfed the web until I found the state-wide standards promulgated by the North Carolina State Board of Education for all public schools K-12. There I discovered that the math I use in the body of the text of my book is required to be taught in all North Carolina schools in grade 9.
So I shall say to my Columbia students, by way of encouragement, that if they made it through the Freshman year of high school, they can handle my book.
As teachers, we do what we can.
