Squealer is a pig who becomes Napoleon's chief propagandist. Manipulating words to achieve a desired effect is his specialty. Much of his writing consists of rewriting previous slogans and rules that had guided the farm animals during the early revolutionary period. Gradually, he switches into bolstering Napoleon's power, which he does largely by discrediting Snowball. He is also skilled at starting and circulating rumors so that the ideas he promotes seem to be expressing popular sentiment.
Squealer's skills become evident in chapter 3 when he delivers a speech justifying the pigs' appropriation of the milk and the windfall apples. Squealer tries to convince the other animals that the pigs are actually making a sacrifice by consuming these things. He relies on the idea that the pigs are using greater brain power, which these foods support, and working on behalf of the others rather than themselves.
"Comrades!" he cried. "You do not imagine, I hope, that we pigs are doing this in a spirit of selfishness and privilege? Many of us actually dislike milk and apples. I dislike them myself …. We pigs are brainworkers …. Day and night we are watching over your welfare. It is for YOUR sake that we drink that milk and eat those apples."
Squealer frequently functions like a press secretary, addressing the animals on behalf of Napoleon. In chapter 9, as food grows scarce in the winter, his persuasive powers are evident in one such address. Squealer explains the principles behind the change in rations, which now favor the pigs. He shows his skill in manipulating facts and figures, in part through repeating dubious claims until the animals believe them.
A too rigid equality in rations, Squealer explained, would have been contrary to the principles of Animalism …. For the time being, certainly, it had been found necessary to make a readjustment of rations (Squealer always spoke of it as a "readjustment," never as a "reduction") …. Reading out the figures in a shrill, rapid voice, he proved to them in detail that they had more oats, more hay, more turnips than they had had in Jones's day ….
