. Cross-Cultural understanding dates back to the discovery of the Third world, its peoples, and its religions. Along this, the place of studying other peoples came in view. Demography and Orientalism were two disciplines which first aimed at studying other peoples regardless of their beliefs. After some thirty years, emphasis was laid on their beliefs, too. Today after disproof of the anticipations of sociolgy founding fathers claiming the disappearance of religious, national, and ethnic predilections in the twentieth century, there has raised the issue of infeasibility of cross-cultural understanding. Morever, many people in the postmodernism school claimed that cultures were languages untranslatable to each other. Cross-cultural understanding is indispensible as well as practical for the human community due mainly to getting closer of the global village. In this, prophets, revolutionary leaders, social reformers, supporters of thought traditions, the practitioners of traditions, discoverers, and inventors are all forerunners of this trend.
