In the morning, the pigs reveal that they have learned to read and write. How is this announcement typical of their behavior in Animal Farm?
"The pigs now revealed that during the past three months they had taught themselves to read and write from an old spelling book which had belonged to Mr. Jones's children and which had been thrown on the rubbish heap." (Chapter II, Animal Farm)
The pigs pride themselves on being more competent to lead. When they announce that they have taught themselves to read, they are boasting of their abilities. They do feel sure of themselves.
The pigs create a code of ethics for all animals to follow. They create principles or rules and create seven commandments as guidelines:
They also paint the basic principles of Animalism on the wall of the barn:
THE SEVEN COMMANDMENTS
1. Whatever goes upon two legs is an enemy.
2. Whatever goes upon four legs, or has wings, is a friend.
3. No animal shall wear clothes.
4. No animal shall sleep in a bed.
5. No animal shall drink alcohol.
6. No animal shall kill any other animal.
7. All animals are equal.
Over the course of events in the story, the pigs change the commandments by adding a stipulation. For example, the pigs begin sleeping in the beds in the farmhouse. The commandment "No animal shall sleep in a bed" is changed to "No animal shall sleep in a bed with sheets." No doubt, the pigs, Napoleon especially, are changing the commandments to fit their selfish lifestyles.
Truly, the pigs, especially Napoleon, feel superior to the other animals. This all came about by the fact that the pigs taught themselves to read.
Ultimately, the pigs take control of the farm. In fact, they turn on many of the other animals, even breaking the commandment that states, "No animal shall kill any other animal."
