from Emmanuel Levinas, Totality and Infinity:
Free beings alone can be strangers to one another. Their freedom which is common to them is precisely what separates them. As a pure knowledge, language consists in the relationship with a being that in a certain sense is not in relation to me, or, if one likes, that is in a relationship with me only insomuch as he is wholly in relation to himself, [Greek word?, looks like kaOavro], a being that stands beyond every attribute –a being, consequentially, completely naked.
