This irony reflects the theme of humanity's vulnerability against nature: it is paradoxical that the human intellect, the pinnacle of evolutionary achievement, capable of understanding and measuring the universe, fails to appreciate nature's power.

Discrimination is a serious issue especially during LaNier’s era. The dress may have been suitable for her first school day, yet segregation in schools prevailed.
