Isolation can be frightening because it can distort one's sense of reality and potentially lead to devastation. How does this theme apply to the...

Beyond Harrison's personal isolation, the ordinary members
of society were isolated (via governmental techniques of physical, mental, and aesthetic
equalizers) from any sense of humanity.  By creating a nation in which all people were
equal--and, thus, "ordinary"--the government eradicated any sense of individualism.  The
government did this because they believed that differences between people would cause
society to become disjointed and unmanageable.  Out of this fear, the government
attempted to rid itself of such isolation (as mentioned above, through equalizing all
citizens).  This method backfired, however, as it created a civilization that was
completely stagnant.  Without individualism, the society lacked the ability to progress
and evolve; it became a mere illusion of utopia (hence, the distorted sense of reality)
at a stand still.  Devastation inevitably arrived with the revolt led by Harrison and
his consequent murder by Diana Moon Glampers.
