Culture can be divided into two types, high culture and low, popular or pop-culture.
However, according to postmodernism (reference needed), the subdivision of culture into high and popular culture is a purely cultural phenomenon. All is culture. Even science is culture. Although someone added that this is postmodernism it is not (yes it is -Reference needed). It is just a rational view on culture, unlike the division of culture into high and low culture which is a typical example of stereotypical thinking.
