AN OFF-TOPIC ESSAY WILL RECEIVE A SCORE OF ZERO.
Think carefully about the issue presented in the following excerpt and the assignment below.
People who like to think of themselves as tough-minded and realistic tend to take it for granted
that human nature is ?°selfish?± and that life is a struggle in which only the fittest may survive.
According to this view, the basic law by which people must live is the law of the jungle. The
?°fittest?± are those people who can bring to the struggle superior force, superior cunning, and
superior ruthlessness.
