Do you believe that we can learn something from Brave New World and Brave New World Revisited and Island?

Since Aldous Huxley's Brave New World Revisited is
essentially a justification of the original novel, Brave New World,
the value of reading it extend from the value of reading the original text. Indeed,
there are valuable lessions that extend from Huxley's
novels:

Technology and science can
desensitize and dehumanize people.

In
Huxley's dystopia, the use of such things as hypnopaedic conditioning programs the
people to have certain attitudes towards other castes, death, nature, etc.  Soma
desensitizes people to anything that might disturb their contentment with their
society.  Entertainment machines generate innocuous leisure and prevent people from
delving into truths or issues that may be disturbing to them.  They do not talk to one
another individually, interacting in a normal social manner; nor do they enjoy and
appreciate nature.

The effort to maintain the
people's happiness prevents them from exposure to the
truth

The government makes life decisions
for the people of the New World; the State censors books and religion because the truths
found in these realms may upset the State's control.  For, it is only when people are
not content, or when they learn the truth about governmental control that people revolt
or disagree with the status quo.  The all-powerful government of the New World with its
World Controllers keeps people in a state of self-delusion.  If anyone demurs, he or she
is banished from society lest he/she disturb the peace.

In
the last chapters of Brave New World, John the Savage says he want disease, he wants
sin, he wants unhappiness.  For, he knows that without these miseries, one is not truly
human.  In order to attain truth and real happiness, one must know
sorrow.
