I had to pare down the original question, so I hope you can repost some of these questions in a more individualized format. For Old Major quotes, you will be sticking to the first chapter in Orwell's work. I would say that some of Old Major's most significant quotes involve his indictment of how the humans run the farm and the vision he has for a world in which the animals own their own means of production. These quotes involve how the animals suffer and how the humans simply exploit them for a benefit that has little, if anything, to do with the animals. Old Major's bringing up of Boxer's strength and utility only until he is no longer useful at which point he will be taken to the "knacker's" is extremely telling. It foreshadows what the pigs will do to him at the end of the novel. At the same time, Old Major's call to action, in terms of rendering his vision of a world in which Animals control their own political and economic narrative and the teaching of the song, "Beasts of England," would constitute some of the most important quotes from Old Major, as it sets the stage for the novel's development.
