Snowball is a deep thinker and more visionary leader than Napoleon. Do you agree?

I would agree with that statement. He is more intelligent than Napoleon but lacks Napoleon’s depth of character. He is also a brilliant orator. Snowball, who represents Leon Trotsky, is a progressive politician and aims to improve Animal Farm with a windmill and other technological advances, but Napoleon expels him before he can do so. In his absence, Snowball comes to represent an abstract idea of evil. The animals blame misfortunes on him, including the windmill’s destruction, and entertain the idea that he is lurking on one of the neighboring farms, plotting revenge. Napoleon uses the animals’ fear of Snowball to create new propaganda and changes history to make it seem as though Snowball was always a spy and a traitor. Snowball’s name is symbolic in this way. Napoleon encourages the animals’ fear of him to grow or snowball so that it becomes so great it is almost palpable. Snowball’s name may also refer to Trotsky’s call (following Marx) to encourage a revolution outside the Soviet Union that would “snowball” into an international proletariat revolution. Snowball can more generally be said to represent systems of belief outside of communism, which the government demonizes in order to lionize its own system.
