The idea of "human nature" (more specifically, "the human condition") was eviscerated by the post-modernists years ago. We can no longer refer to anything resembling a unified "condition" of our experience because, as the post-modernists aptly point out, we no longer have what can be called a "grand narrative." Our experiences as human beings are too diverse to apply universal ideals to us as humans.
One way to look at it is this: "War" (both semantically and culturally) has a multitude of meanings depending on the individual. For example, my view of the word varied greatly from a former co-worker of mine whose family had fled war-torn Somalia. An insensitive manager of the store I worked at had thought it was a good idea to post a "War Board" (and it was labeled as such) in the staff room as a "cute" way to establish and record our sales targets. I immediately took a pink highlighter and turned it into a "No War" board. The idea was subsequently scrapped.
Also consider that "greed" would likely have varying meanings to the following people:
- A fifty-something, male, Caucasian CEO of a large multi-national based in New York City, who's from an affluent family.
- A recently unemployed single Black mother of three, whose home was destroyed by Hurricane Katrina in New Orleans.
- An Aboriginal in Australia whose family has been fighting fruitlessly to have their native land returned to them by the government.
- A Buddhist monk from Tibet who has been subject to humiliation and physical punishment for eight years in a Chinese prison because of his religion.
There are no grand narratives... only small ones. "The human condition" should not be applicable to this discussion.
