How would the revolution in George Orwell's Animal Farm have been different if all the animals were able to read?

Perhaps the animals would have been a little more critical—and therefore willing to resist—many of the pigs' abuses. The pigs' literacy enables them to read Jones's books, some of which give them ideas about how to run the farm and propel them to leadership positions. Their command of language enables them to justify their actions through changing the original commandments on the wall of the barn. It should be noted, though, that the power of the pigs' propaganda confuses even some of the literate animals. When Squealer alters and distorts historical events, the animals struggle to recall whether what he is saying is true, and they eventually, with great confusion, accept what he says. When Muriel reads the newly altered Fourth Commandment, for instance, Clover vaguely thinks it used to read something else, but concludes, "as it was there on the wall," it must have said something about sheets.
