The theme of the novel Matched focuses on the importance of freedom in society. In Cassia's society, there isn't much if not any freedom. People follow specific rules, they know when they die, who they love and what their destiny is supposed to be. Cassia believes that the rules are important and should be followed but then starts to later doubt her previous thoughts later in the book. She loves someone other then who she was destined to be with which puts up a huge red flag in her brain because everything she ever thought to believe is now being questioned. I think another important theme shown in this book is the idea of a perfect society. This world that Cassia lives in seems like a "perfect" society, a utopia, but if you look hard enough, you are able to see cracks in the perfection. This utopia then begins to seem like a dystopia, where the government takes away basic human rights like who a person is to fall in love with and the time of their death. No society can ever be truly perfect and taking away a person's rights will not change that.
