What is a good thesis for a literary response based on the "Brave New World" book?
Wow! That's a pretty open-ended question.
What you need to do first is come up with something that interests you about the novel. This might be something to do with a class society, how females are treated in the novel, whether you think BNW is a dystopian or an utopian novel, the plight of the individual in a collectivist society, the impact of BNW on today, etc. Once you find that something that interests you you should brainstorm or mind-map out all aspects of that subject on paper. Write down arguments, quotes--anything which pertains to that subject. When you've done all that you can make a thesis statement that reflects your subject matter. It's tough for a teacher to "give" you a thesis statement since you need to write about what interests you and what you see is important in the novel. What interests you about the novel? What themes affect you or today's world? What is important about the novel's characters? What do we learn and take away from the novel? Can you approach the novel using a literary theoretical school such as feminism, Marxism, psychoanalytical criticism, existentialism? These are all avenues for exploration. Let me know what what you see as notable in the novel and i can prompt you further.
