A conflict is a struggle between opposing forces. All stories have a conflict,
a major problem that involves characters of some sort. Complications in the
 plot create tension and further conflict.

Every plot is built around conflict in order to create interest and build suspense. Readers want to know how characters react to conflict and how the characters
 resolve their problems.

Conflict in literature can take several forms. Often, more than one conflict is
apparent, usually one is primary.

1. Conflict with others sets one character against another and is the most basic
kind of conflict.

2. Conflict with society sets one character against accepted ways of thinking and behaving. Since society is made up of people, this is conflict between people on a larger scale. Religion falls within this category.

3. Conflict with self involves a struggle that takes place within a character. It occurs when an individual is confronted with a difficult choice or and unpleasant situation.

4. Conflict with nature sets a character against the forces of nature.

5. Conflict with the unknown sets a character against that which is beyond human comprehension: fate, magic, death, or God.

6. Conflict with machines has been added to the mix in the last few years.
