What is one difference between the schoolmaster and the students?

After the gentleman finishes his speech, the schoolteacher, Mr. M'Choakumchild, begins his instruction. He has been trained in a schoolteacher-factory and has been conditioned to be dry, inflexible and uninspiring‹but full of hard facts. His primary job in these preparatory lessons is to find "Fancy" in the minds of the children and eradicate it. While the students have imagination and creativity Mr. M'Choakumchild is there to destroy it. While the students are not literally danger (M'Choakumchild), their childish imagination has been targeted for annihilation. This completes the archetype of youth vs. age, and foreshadows that whoever is being targeted and singled out (Cecilia Jupe and her imagination) will ultimately escape this tyrant, but other innocents will be less fortunate (Bitzer). But we might expect as much from the same author who had written A Christmas Carol a decade before.

I think the diff is something.
