Does Eating People Is Wrong have a resemblance to George Orwell's novel 1984?
The main resemblance I see between the two is that they are both satires; although whereas Orwell's work is largely a political satire, Bradbury's work is a social satire. Beyond that, Orwell's piece deals in the dangers of a dystopian society, while Bradbury's works deal with a protagonist who is trying to fit in with his society and failing miserably because he cannot adjust and adapt himself to the customs of the time.
Both novels also deal, to an extent, with "future" but in the case of the Bradbury work the future is the present. The problem is that Treece is unable to accommodate himself to it. He is a liberal humanist in an environment that does not support liberal humanists. He does not fit in. In this sense, environment is a factor in both works. In 1984, a totalitarian regime controls all. In Bradbury's work, the norms of academia are in control, and Treece struggles to match his own mores with those of his society.
