In George Orwell's "Animal Farm," Napoleon initially opposes the idea of building a windmill, primarily because he is focused on consolidating his power and does not want to divert resources away from his own interests. However, he eventually uses the windmill as a tool to manipulate the other animals.
To provide specific quotes and pages, I would need the edition of the book you're using, as page numbers can vary between editions.
In general, early in the book, Napoleon disagrees with building the windmill because he believes that it is not a priority and may distract from their current focus on food production and safety from humans. However, once he sees the windmill idea gaining traction with the animals, he decides to support it to gain their loyalty and distract them from their suffering.
If you can specify the edition or if you’d like me to summarize themes or concepts further, let me know!
