In "Brave New World," tyranny and fascism are embodied by what symbol? What symbolizes the heart and soul of humanity?
I would also consider their entire "reproductive" and "education system" to be symbols of fascism. A fascist society has to go to great lengths to "create" the population that they wish. In "Brave New World" they skip some of the difficulty by creating citizens who perfectly fit their plan/use for them (sounds frighteningly like "The Republic"), and before they are able to create "bad" thoughts, they educate them to the "right" ideas. Of course, this all does relate to Ford and his assembly line. The "manufacturing" of people in the opening section of the book mirrors the assembly line, culminating in the somewhat frenetic dialog that discusses the horrors of the "old" life. I don't know if this is techically a symbol ... if you need an object, perhaps it would be bottles in which the young a decanted.
And I would have to agree that Shakespeare is the heart and soul of humanity as WE see it; certainly not as the residents of BNW see it.
In "Brave New World", the drug soma and the Model T both symbolize tyranny and fascism. Soma is a drug that allows the state to totally control its citizens. It gives them an instant feeling of happiness, no matter what the circumstances. In addition, it shows the influence of science and manufactured happiness on the populace. The Model T and the constant mention of Henry Ford also reminds the audience of the assembly line and the unchanging consistency in everything that Ford exemplifies. The heart and soul of humans seems to be represented by John's love of Shakespeare. Shakespeare deals with all of the human emotions in his plays and his intense, powerful language along with his often tragic endings are a model of humanity the Brave New World wants to ignore.
