Most dictionaries define a narrative as telling about consecutive events. However i frequently see in philosophical works and discussions, especially postmodernist ones, the use of this word in such way, where it doesn't make sense for me. Examples:
... with his claim that the postmodern was characterised precisely by a mistrust of the grand narratives (Progress, Enlightenment emancipation, Marxism) which had formed an essential part of modernity.
This is the narrative that Drudge is trying to create, especially on slow news weekends when there's nothing real to aggregate and post: The blacks are rising up and attacking the whites. Black people are angry and they're taking over!
I don't understand how is Marxism a narrative, when it is a body of theories, rather than a storytelling, and how somebody's supposition of black people being evil is a narrative too.
What is narrative? How do you define it and why there is a need for such a term in contemporary philosophy?
