To quote Vijay Prashad paraphrasing Marx: Those who seek to change the world understand it better.

Every cadre should be a theorist, and every theorist should be a cadre; this separation between the proles who actually go and experience reality and the "theorists" who describe it while being alienated from it is bound to go nowhere. You need to have the workers educated in political theory, and you need to have the theorists close to the ground where they can experience history unfolding.
