Note: I misread the question - revision next. You have been
given the gift of moving to a new planet with primitive
intelligent life and are in a position to influence the future
of their inhabitants by choosing and taking only one of each of
the following: 1.A philosophers entire work 2.A country's entire
history 3.An artists entire masterpieces 4.A musicians entire
work 5.A writers entire literature.
As always, support your work with reasons.
My answer: A writer's entire literature.
Why?
Stories.
People are more quickly inspired by example, either for or
against and digest more readily things that are relateable.
Even a bad author will teach things about life and give models
for people to form after or against.
Multiple competing philosophies can be embedded within a
characters words and actions. Even non-fiction talks about
people.
I wanted to say music *really* badly. But ... people can make
their own music. They can tell their own stories too, but
experience comes first. If you can short-circuit the need to
experience death by a fictional character dying instead, you can
life vicariously through their experience and understand it
better.
Children have died thousands of times thanks to cartoon and
video game deaths. I believe it helps at some level.
