“To be ethnocentric is to divide the human race into the people to whom one must justify one’s beliefs and the others. The first group – one’s ethnos – comprises those who share enough of one’s beliefs to make fruitful conversation possible. In this sense, everybody is ethnocentric when engaged in actual debate, no matter how much realist rhetoric about objectivity he produces in his study.” -Rorty, Richard. Objectivity, Relativism, and Truth: Volume 1: Philosophical Papers (pp. 30-31). Cambridge University Press. Kindle Edition.
This, of course, will put a bit of a scare in many of my progressive peers. And at a more nominal level (as well as popular), ethnocentricity is looked at in racial terms. But here Rorty is expanding the term. And it is important to understand how he is doing so. As Voltaire argued:
If you want to talk to me, define your terms.
And it’s not like Rorty is really departing that much from the generally accepted understanding of the term. Even in the more nominal/racial sense of the term, the ethnic is still about a community that shares certain beliefs and understandings of the world (or reality (that community happens to live in together. Therefore, Rorty’s point equally applies at the more nominal level. Neither situation offers hope of totally opposed ethnicities (and “opposed” is an important term here since it involves different realities (being able to productively communicate with each other. Note, for instance, our progressive difference with the right under Trump. Trump and his followers, by Rorty’s understanding of the term, are of a completely different form of ethnocentricism.
I see this all the time (as a progressive in Nebraska (with my dear rightwing friends. From an ethnocentric perspective, on one hand there is no point in us discussing politics since it could not possibly be productive; on the other, and from an ethnocentric perspective as defined by Rorty, we can still interact due to our shared experience in other areas.
Likewise, I can still (as a white heterosexual male( share a kind of ethnocentricity with people of other races, genders, and sexual orientations through whatever shared belief systems and assumptions we happen to have: we can still engage in productive discourse.
