Dr. Stockmann: "They [the young] are the people who are going to stir up the fermenting forces of the future, Peter."
Here we see the contradictory natures of the two brothers. The Doctor is all about progress and change, where as the Mayor is for keeping everything just the way it is. The Mayor sees the Doctor's progressive tendencies as dangerous, because they challenge the established order of things.

Mayor Peter Stockmann: "I am entitled to request most emphatically that all arrangements shall be made in a businesslike manner, through the proper channels, and shall be dealt with by the legally constituted authorities." (1.103)
To the Mayor, rules are everything. They give him power as well as a personal identity. These rules are so important to him that he becomes symbolic of the traditional order, which Dr. Stockmann comes to believe is corrupting all of society.

Morten: "I should like best to be a Viking."
Pagan is the overall term for a person who is not Christian. When Billing encourages the child in this notion, he's being pretty scandalous. In Ibsen's time, Europe and pretty much the entire Western world was strictly Christian. Systems of morality, social conduct, and even government were based on Christian ideals. Many of Ibsen's plays express a longing for Norway's pagan Viking past and harshly critique the strict moral values of the Christian establishment.
