Read the books linked in the other comment.
Or, you can start with the modern commie og.
He taught classes to Marx, but you never hear his name.
Except in connection with doing time for having a barter bank with more money than the gov't of france.
They labeled him a criminal, stole his bank and put him in prison, if you can believe it.
He squared up with his customers after he got out, years later.

Once you have read those 3, you will have gained on the advanced class.
