How do symbols to enhance plot, character, setting or theme?

Integral setting is when the action, character, or theme are influenced by the time and place, setting. Controlling setting controls characters. If you confine a character to a certain setting it defines the character. Characters, given these circumstances, in this time and place, behave in this way. I got this from some of my notes.
