Kwame Nkrumah used to say that, "Thought without practice is empty and action without thought is blind." Not sure if a truer statement has ever been uttered. We must be both thinkers and doers. It is not enough to know. We must also act. What good does it do us to have knowledge if we don't act on it? But we must also have a knowledge base from which to base our actions. Frustration and anger and rage are not enough. And being mad at white people is not enough. We must engage in conscious and thoughtful action.
