I hope some day I will write a dissertation about Levinas and intercultural contact. I don't have time now, but at least I can express my thoughts on this blog. Levinas says that a relation becomes ethical when I meet another person. The image I create of the other can never coincide with the real person. An individual is unique, he can't be reduced to the (supposed) characteristics of his group. So I should have an open mind for the real person and let go of my prejudices anytime.
