According to Helen Keller, knowledge is important to set us free. Justify this in light of the novel.

Helen Keller is a prime example of how knowledge can set people free. As a young girl, she was unable to speak or communicate in any way, and her knowledge was extremely limited. The autobiography goes through the terrible prison this was for her. She was unable to express the complex thoughts, and more importantly the feelings, she had.
When she began working with Miss Sullivan, her life radically changed. When she realized that, through physical touch, Miss Sullivan was able to communicate with her and she was able to respond in kind, she became overjoyed and felt free. The ability to convey thoughts and share knowledge, as well as learn about the world, freed her from a self-contained prison of disability.

In her memoir, Helen Keller, who became blind and deaf at the age of 19 months, shows how education changed her life and set her free.
As a growing young girl, Keller became increasingly angry because she had no way to communicate her more and more complex thoughts and desires. She started having daily tantrums and meltdowns. Her parents became so alarmed that they took her to meet with specialists. This resulted in the family hiring a tutor, Miss Sullivan, to work with Helen.
Helen describes Miss Sullivan's arrival as a radically important event, as important as the parting of the Red Sea to freeing the enslaved ancient Israelites. As she puts it:

Thus I came up out of Egypt and stood before Sinai, and a power divine touched my spirit and gave it sight, so that I beheld many wonders. And from the sacred mountain I heard a voice which said, "Knowledge is love and light and vision."

Once Helen realized that the writing Miss Sullivan was doing in her palm corresponded to objects in the real world, Helen's entire world exploded into life. She wanted to learn everything. She knew, from being formerly trapped without any access to education, that knowledge does set you free because it allows you to understand your environment and the larger world and to enter into loving relationships with other people.
