Sorry that was a lazy answer - if you're looking for a simple, easy to understand description honestly Mike Duncan's episode The Three Pillars of Marxism has one of the most concise and simple descriptions that a layperson could understand. You don't have to listen to the whole episode but I think he finished with diamat in the first 15 mins if I remember correctly.
