Book excerpt: The rise of technology and ease of spread of information has facilitated the diaspora of new ideas in the community. The penetration of new ideology and new values challenges the status quo of value and morality in our community. While this can be seen as an opportunity to evolve as a nation, the introduction of radical and separatism brings chaos to the community. This issue is not only experienced in Indonesia but also in the whole world. The needs for a solution and academic forum to discuss this postmodernity in society bring us to the The 4th International Conference on Law, Education and Social Sciences (ICLSSE) 2022. This conference is an international forum to disseminate knowledge and research development among researchers, scholars, professionals, and those interested in research interests in Law and Social Sciences and Social Education. This conference was organized by the Faculty of Law and Social Sciences, Universitas Pendidikan Ganesha. The theme of this fourth conference is "Race, Ethnicity, and Nationalism in Postmodern Society: Opportunities and Challenges".
