I believe that the lines from Antigone that show a result of Creon's change in fortune, or his peripeteia are:
<em>Thy wife, the mother of thy dead son here,
</em><em>Lies stricken by a fresh inflicted blow.
</em>It shows that both his son and his wife are dead because of his bad decisions.
When their is so much diversity in an environment, differences tend be well-regarded and even nurtured. Conformity and unity is difficult to achieve since the environment is very diverse. Individuals are then motivated to think differently and critically. The result is that critical thinking is cultivated in the environment.
