What is the thesis of this sentence 'All people are born with a dark/evil side' "In Lord of the Flies"?
This statement is the thesis! Now you have to back it up by giving supporting evidence (examples from the text). Jack's natural bent to savagery is not really put to question here (since he's clearly just that way from the start anyway), but what about the others, especially Ralph? How does Jack's bloodthirsty lust for the hunt "contaminate" the other boys? How do the boys degenerate over time? How does Raph oppose this? How does he give in? What is the role of Simon, also somehow caught in the middle? Only Piggy comes out "clean," and he gets himself killed....
The reference below gives three different interpretations of the novel. Check out particulary the Freudian one, which comes the closest to your statement.
Parker Lee is correct. The thesis is that all people are capable of evil and that is part of being a human being. Golding was writing at the end of World War II after all the Nazi atrocities had been discovered. People were questioning how such evil could occur. Golding suggests that evil is part of the make-up of man's personality and it can only be contained by effective laws and good government. In Lord of the Flies, Ralph is not a truly effective leader. He tries to placate Jack, like the British did with Hitler. In the end, Ralph ends up losing his authority and almost his life to someone who is willing to let his "dark side" out.
This thesis states that all people are born with a dark or evil side, thus implying that without the controls of a civilized society, people can regress to savagery or the acceptance of evil as many of the boys do in "Lord of the Flies."
However, in the novel there is at least one character whose intrinsic nature contains no evil. And, since the use of "all" is illogical if there is just one exception, you may wish to disprove (dispute) this thesis.
As most of the others have said, this statement is the thesis. Your teacher probably asked you to give evidence to prove this statement true.
