What is the symbolism of the fence in Fences?
The idea of the fence has a number of meanings in the play. Fences keep things in and keep things out, both literally and figuratively for the Maxson family.
For Rose, the fence represents an opportunity to define and defend her family.
Rose thinks the partially built fence around the house will keep her loved ones safe inside.
For Troy, the fence has a more symbolic set of meanings.
Unable to open up to those that he loves, Troy keeps much of his emotion inside, building imaginary fences between himself and his family and friends.
Beyond symbolizing the idea of Troy's inability to communicate his emotions and his affection, fences also characterize Troy's view of the challenges he has faced in his life.
He feels restricted by race in his professional life, as he did in his athletic career. Death also represents a significant limitation for Troy, fencing off his potential in an absolute, inevitable and definite way.
Troy's rivalry with death can be seen as indicative of his mindset generally. Where Troy sees limits, he feels that he is being personally challenged to overcome those limits.
When Troy played baseball, he was never content to hit the ball into the stands. His hits always had to go over the fence.
What was true for Troy as a baseball player is true for him as a husband and father as well. When Troy feels powerless or limited, he acts out. We see this in his assertions of power over Cory (demonstrating that he will not be limited in his authority as a parent) and we see it as well in his adultery.
Every limit he perceives, he seeks to defeat somehow, including the limit of death.
In part, the fence symbolizes Troy's futile attempt to keep death and misfortune away from himself and his family. He addresses death in the play and says, "Mr. Death. See now....I'm gonna take and build me a fence around this yard...And then I want you to stay on the other side." He believes that constructing a fence will make him immune to misfortune, but his attempts are not effective. Instead, his mistress, Alberta, dies, as does Troy, eventually. A fence cannot keep death at bay.
Building fences is also Troy's attempt to wall himself away from the outside world and from other people. He believes in his core that the world is a hostile place to an African-American man, and he thinks that his son, Cory, will not be able to play football with whites. He says, "The white man ain't gonna let him get nowhere with that football." Troy even eventually places Cory's things outside the fence when he can no longer get along with his son. Essentially, Troy walls himself off emotionally from most of the outside world, believing it is a place in which he will receive no acceptance. He also walls himself off from his family and lives in a world of emotional isolation.
in my opinion, "fence" in fences plays symbolize of the obstacle in life. like a Bono's statement "some people build fences to keep people out, and some people build fence to keep people in".. so i think that "fences" means if the obstacle could make people stuck in their problem and do 'nothing'.. while we also must be able to disengage from obstacle and struggle to solve the problem itself, so that we can find a happiness by our own way :)
