The paper is examining a fundamental new understanding of interculturality. It does so by starting with a sense of wonder about the stranger / the foreign resulting from a lack of knowledge about him/it, that should not be overcomed, such as the philosophical wonder in Aristotle, but deconstructs the ever culturally preformed "thinking as usual".
In place of a rigid boundary between the familiar and the foreign it enters the model of horizon in which the (temporalized) wonder about the foreign takes place.
