Helen Keller writes in The Story of My Life about how her teacher, Anne Sullivan, taught her in the outdoors. She writes in Chapter V:
"Long before I learned to do a sum in arithmetic or describe the shape of the earth, Miss Sullivan had taught me to find beauty in the fragrant woods, in every blade of grass."
Sullivan brings her student to nature to learn about the world around her and to teach her the names of objects in nature using sign language.
Nature also helps Keller learn the meaning of abstract ideas. As she is trying to understand what love means, she observes the following in nature:
"The sun had been under a cloud all day, and there had been brief showers; but suddenly the sun broke forth in all its southern splendor."
The natural world allows her to understand more complex concepts such as love, as she equates the appearance of the warmth of the sun after a day of storms with the concept of love. By bringing Keller outside, Sullivan makes her lessons enjoyable. As Keller writes, "The loveliness of things taught me all their use." Keller's early enjoyment of her lessons outside causes her to be eager to learn more, setting her on a path that will take her to Radcliffe College (then the sister school of Harvard) and to a life of learning, speaking, and activism.
