What is literature and does it matter?

After reading chapter 2 “what is literature and does it matter,”  Jonathan Culler doesn’t tell us what the definition of literature is, he just makes some examples in some aspects to make readers to know literature. I think the most important aspect of this section of the chapter is to understand literacy and non-literacy correctly. Reflection is a necessary factor in literature. Non-literacy is easy for people to understand, and not to ask questions. “But ‘thing’ in the phrase ‘a curious thing’ is not a physical object but something like a relation or aspect which doesn’t seem to exist in the same way that a stone or a house does”, it indicates that the writer describes the object vaguely that he writes, so that reader can not understand and point out what the object is. People are likely to get more information and want to know more,  they also are curious about implicit meanings of literature.

One question that stays with me is that “What is involved in treating things as literature in our culture?”
