Woodson reiterates his conviction that education’s power lies specifically in its ability to teach critical thinking, which in turn is the key skill necessary to improve and transform the world. Since critical thinking really just means assessing evidence in order to make judgments and take action, he thinks that Black people have to assess the facts of their own history in order to decide how to improve their situation. Woodson refers his readers to his textbook so that, if they so desire, they can start truly educating themselves about Black life and history.
