Out with the old, in with the new: in Animal Farm, the animals get rid of an old set of rules just to find themselves oppressed by a new one. At first, new commandments and traditions are supposed to energize and unite the animals. But these rules turn out to be not so much rules as easily changed suggestions—especially because most of the animals don't read so good (and don't remember so good, either). Instead of preserving order, rules are used to deceive and abuse. Gee, it's a good thing that never happens in ourworld.
The shifting rules, customs, and traditions of Animal Farm parallel the decay of Animalism and the ideals of Old Major.
Although the pigs have many ways of oppressing the other animals, their use of rules and order is the most powerful.
