In the novel Animal Farm by George Orwell, how do the animals show that education is the key for unification?

Following old Major's speech and subsequent death in Chapter 1, the pigs begin organizing old Major's revolutionary thoughts and ideas into a system called Animalism. Several nights per week, the animals secretly assemble in the barn at night, and the pigs expound upon the principles of Animalism, teaching the other animals that there is a better way of life without Mr. Jones. In the beginning, the pigs are met with much resistance from animals loyal to Mr. Jones or worried about the concept of taking care of themselves. However, the pigs continue educating the animals about their dismissal, oppressed lives and they eventually win the support of the majority of the animals.
Before and shortly after the Rebellion, Orwell portrays how education is key to unifying the animals. The pigs' ability to educate the animals during their weekly secret meetings demonstrates how education is fundamental to unification. The animals begin thinking in one accord and eventually rebel against Mr. Jones after he forgets to feed them for several days. Following the Rebellion, the pigs continue to educate the animals by elaborating on the principles of Animalism and creating the Seven Commandments. The pigs even attempt to teach the other animals how to read and write, which stabilizes their community and further unifies the animals.
