For the first time in her life things are making sense. She grabs her teacher's hand and drags her from the grass, to a tree and then to a doll. Each time she makes the teacher spell it out for her.

One could read any treatise on epistemology, including Rand's, and never fully grasp the important lesson that is taught in this one movie. The producer did not intend to give a lecture on epistemology. But in the end he gave one of the most important lectures on the subject ever given. This film, this myth if you please, makes real the need for rational epistemology. In the same way, Rand's novels presented the alternative myths needed in our culture.
