'golding expresses that anyone, even prepubescent boys, can be capable of murderand anarchy'
Is that a good thesis for a literary essay?
That sounds like a great thesis. You can either stick completely with this novel and refer to the different characters who change into killers--Jack, Roger, even Ralph and Piggy join in during Simon's death, or you can tie in other novels that have similar themes. A Separate Peace fits into this as well. Perhaps even Bob Ewell from To Kill a Mockingbird would fit in as well. Whichever route you take, make sure to use examples from the text to back up your points. Good luck!
Ayana, you are 3/4 there. Your theme is almost outstanding. What you need to add is your plan. That is what an explicit thesis is.
The thesis is your plan or guide on how you are oging to write your essay. An explicit thesis statement lists the controling ideas that will guide your essay. For example: if you added "Golding's use of imagery, ironic diction, and symbolim reveals that anyone, even prepubescent boys, can be capable of murderand anarchy." The controlling ideas are 1) imagery, 2) ironic diction, and 3) symbolism.
By explicitly stating your controlling ideas, your paragrpahs will follow naturally from this. Your next paragrpah should be a topic sentence about imagery, and so on.
Now, on the other hand, if you left your thesis the way it is, that would be an implicit thesis statement. But, the problem for most students have is that an implicit thesis statement leaves them confused and puzzled over what to do next.
They can't focus because the students don't have any controlling ideas or didn't think of any. So if you spend soem time on the controlling ideas, "the paper will organize itslef."
