"Karl Marx said, “The task is not just to understand the world but to change it.” A variant to keep in mind is that if you want to change the world you’d better try to understand it. That doesn’t mean listening to a talk or reading a book, though that’s helpful sometimes. You learn from participating. You learn from others. You learn from the people you’re trying to organize. We all have to gain the understanding and the experience to formulate and implement ideas."
