The purpose of a narrative report is to describe something. Many students write narrative reports thinking that these are college essays or papers. While the information in these reports is basic to other forms of writing, narrative reports lack the "higher order thinking" that essays require. Thus narrative reports do not, as a rule, yield high grades for many college courses. A basic example of a narrative report is a "book report" that outlines a book; it includes the characters, their actions, possibly the plot, and, perhaps, some scenes. That is, it is a description of "what happens in the book." But this leaves out an awful lot.
Locke attacks both the view that we have any innate principles (for example, the whole is greater than the part, do unto others as you would have done unto you, etc.) as well as the view that there are any innate singular ideas (for example, God, identity, substance, and so forth). The main thrust of Locke’s argument lies in pointing out that none of the mental content alleged to be innate is universally shared by all humans. He notes that children and the mentally disabled, for example, do not have in their minds an allegedly innate complex thought like “equals taken from equals leave equals”. He also uses evidence from travel literature to point out that many non-Europeans deny what were taken to be innate moral maxims and that some groups even lack the idea of a God. Locke takes the fact that not all humans have these ideas as evidence that they were not implanted by God in humans minds, and that they are therefore acquired rather than innate.
