According to Douglass, the knowledge that was kept from the slaves was the knowledge of their own identity, the knowledge about themselves. They do not know about their parentage, as well as their birthdays. They do not know any knowledge about their personal background and these kept them from acquiring their own education, and learning how to read and write. Hope this answers your question.
Any Republic or Country needs a Constitution which specifies rights of its people for a Govt is based on Rights & Freedom of its Citizens Govt is formed by the people to work for its people!!!
