Books
Explanation:
In "My Bondage and my Freedom" by Frederick Douglass, Douglass explains how he started forming the belief that people deserved to be free. Douglass first developed this belief when he began reading books. He tells us that the moment he learned how to read, a new world opened up to him. He began to have thoughts that he had never had before, and this inspired him to follow the path of abolition.
