Today, it's my turn to give the weekly oral report. I have been assigned the life of Emily Dickinson. Compared to Walt Whitman whom we discussed last week, I found Emily Dickinson strikingly different. She seems the complete opposite of Whitman in her life and in her work. I will start by sharing with the class some essential facts of her life. Emily Dickinson was born in 1830 in Amherst, Massachusetts, barely a decade after Whitman. In her early twenties, she began to withdraw from ordinary contact with the world. The reasons for this still remain a mystery, although researchers currently believe that she may have suffered an emotional collapse after the loss of her teacher and good friend. For the remaining 30 years of her life, she was seldom seen outside her home. In this respect, she was quite unlike Whitman, who loved the great outdoors. Emily Dickinson spent her lonely days corresponding with friends and writing hundreds of remarkable poems, notably "I Heard a Fly Buzz," and the poem we prepared for class today, "I'm Nobody." Although she showed some of her poems to her family and sent some in letters to her friends, only four were published in her lifetime. Most of them, almost 1200 altogether, were discovered in her room after she died in 1886 at the age of 56. These poems shocked the literary community and established her as a major poet. Several modern critics consider her the greatest female poet in the English language. Uh, that's about all I have. Are there any questions? If not, we should probably begin talking about Dickinson's "I'm Nobody," the poem Prof. Meyer assigned for this week's class discussion.

Why did Emily Dickinson separate herself from the outside world?
